The repolarization of cardiac muscle cells involves  c. exit of potassium through voltage-gated channels

In cardiac muscle cells, repolarization after an action potential is initiated by the opening of voltage-gated potassium channels, which allows potassium ions to exit the cell. This outward flow of positively charged potassium ions causes the membrane potential to become more negative, or to repolarize, after it has depolarized during the action potential. The exit of potassium ions is the main factor responsible for the repolarization phase of the action potential in cardiac muscle cells.

Option a, e and d are incorrect as they involve either the opening of sodium channels or the binding of acetylcholine, which are not involved in repolarization of cardiac muscle cells. Option b is incorrect as calcium is involved in the plateau phase of the cardiac muscle action potential, not in the repolarization phase.

Genetics is the branch of biology that studies how traits are passed down from one generation to the next.

Here are the definitions and examples of the three types of dominance in genetics:1) Complete dominant: This occurs when one allele completely dominates over the other. In a heterozygous genotype, the dominant allele will always be expressed. For example, if a pea plant with the genotype Rr (where R is the dominant allele for round seeds and r is the recessive allele for wrinkled seeds) is crossed with a homozygous dominant pea plant (RR), all of the offspring will have round seeds because the dominant R allele completely masks the recessive r allele.2) Incomplete dominant: This occurs when neither allele is completely dominant over the other, resulting in a blending of the two traits. In a heterozygous genotype, a third phenotype is expressed which is a combination of the two alleles. For example, if a red flower (RR) is crossed with a white flower (WW), the F1 generation will all be pink (RW).3) Co-dominant: This occurs when both alleles are equally dominant and both traits are expressed in the phenotype. In a heterozygous genotype, both alleles are expressed without one dominating the other. For example, in the human blood type, the A and B alleles are co-dominant. If a person has both A and B alleles, they will have the AB blood type.

Explanation:

Answer:

Bears and lizards are more closely related.

Explanation:

The chart shows the branches of the species. The relativity of each species to each other shows how closely related they are.

organisms that are placed close to each other and have a nearly common ancestor have some similarities, so the bear and the lizard are closer to each other than the newt because they are closely present in the cladogram.

The cladogram is the diagrammatic representation of the animals and shows how the organisms have evolved and their special traits. This cladogram explains how the species show commonness and difference, such as the bear and the chimpanzee, which are both derived from the common mammal ancestor.

From the common amneote ancestor, the lizard, bear, and chimpanzee are descended, so they all have the traits of the amneote. From a common tetrapod ancestor, the newt, the lizard, the bear, and the chimpanzee are derived, and all have some characteristic of the tetrapoda.

Hence, the bear and the lizard are closer to each other than the newt because they are both present closely in the cladogram.

Explanation:

Greater productivity is NOT present for communities with high species diversity. When discussing a community's diversity, the term "species diversity" is used to describe the number and abundance of different species that are present in an area.

The presence of a variety of species in a community is beneficial in numerous ways, and as a result, communities with high species diversity are able to exhibit certain traits such as resistance to invasive species and the ability to withstand stressors. However, greater productivity is not one of these traits. Greater productivity is related to the number of organisms present in a given area. In ecosystems with high species diversity, species can compete for resources, resulting in a lower number of individuals per species. As a result, these ecosystems may exhibit lower productivity rates than those with a smaller number of species. Communities with high species diversity are more resilient to disturbances than those with low species diversity. Because a wide variety of species are present in communities with high species diversity, it is less likely that a disturbance or invasive species will completely decimate the entire community. As a result, these communities are better able to withstand stressors than those with low species diversity.

Explanation:

Its like each step up in the food web/pyramid.

Trophic level is a living organism's position in the flow of energy through an ecosystem. The correct option is D.

A biological organism's place or function in the movement of energy through an ecosystem is referred to as its trophic level. It symbolises the ecological community's hierarchy of feeding.

A trophic level's inhabitants have comparable feeding habits and occupy a certain place in the food chain.

The first trophic level is occupied by the primary producers, including plants and algae, which use photosynthesis to transform sunlight into energy.

The second trophic level is occupied by herbivores that consume producers directly, followed by primary carnivores (predators that consume herbivores) on the third level, and so forth.

A complex network of energy flow and nutrient cycling occurs within an ecosystem at each trophic level as creatures consume and are consumed by one another.

Thus, the correct option is D.

Answer: it's better to do a small area at a time other than doing large areas where it will be hard to find specific species throughout the huge amount of land

A quadrat is a small, designated portion of the entire area to be sampled that is marked off so that the population within it can be counted by hand or by a similar method, like by taking an aerial photograph.

Quadrat sampling provide an accurate estimate of a population size within a defined area:

Quadrats allow researchers to study plant and animal populations spread out over large areas. They are inexpensive, relatively easy to design and adaptable for studying unevenly distributed populations.

Quadrats work well for observing changes to whole populations over time, including distribution patterns, nesting and overall health.

Quadrat sampling is a classic tool for the study of ecology, especially biodiversity. It is an important method by which organisms in a certain proportion (sample) of the habitat are counted directly.

It is used to estimate population abundance (number), density, frequency and distributions.

A quadrat is a small, designated portion of the entire area to be sampled that is marked off so that the population within it can be counted by hand or by a similar method, like by taking an aerial photograph.

Quadrat sampling methods are time-tested sampling techniques that are best suited for areas where access to a habitat is relatively easy.

Advantages:

- It sampling is easy to use and is inexpensive.

- It is suitable for studying plants, slow-moving animals and faster-moving animals with a small range.

- It requires the researcher to perform the work in the field and, without care.

- It measures abundance and needed cheap equipment.

Disadvantages:

- There exists biasness in favor of slow moving taxa.

- Collect only taxa that are present in the sampling time and not buried too deeper in sediment.

- It is a low estimate of taxonomic richness and assemblage composition.

- It is also a low detectability of among-site differences in assemblage composition.

- Some animals may experience harm if the scientist collects the population within the quadrat rather than studying it in the field.

Applications:

1. Quadrat sampling is broadly used in plant studies.

2. It is applied in ecology especially in biodiversity.

3. It is used to find the taxonomic richness of slow-moving taxa in a certain area.

4. It is the best measure of finding taxonomic richness in costal area.

5. It can be also used to evaluate the impact of weathering, trampling or erosion in an ecosystem or at a cliff or rock face.

Answer:

The earth system is itself an integrated system, but it can be subdivided into four main components, sub-systems or spheres: the geosphere, atmosphere, hydrosphere and biosphere. ... The atmosphere receives energy from solar radiation which warms the earth's surface and is re-emitted and conducted to the atmosphere.

Answer:

When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle, and a solid crust. Our home planet Earth is a rocky, terrestrial planet. It has a solid and active surface with mountains, valleys, canyons, plains and so much more. Earth is special because it is an ocean planet. Water covers 70% of Earth's surface.

Earth's atmosphere is made mostly of nitrogen and has plenty of oxygen for us to breathe. The atmosphere also protects us from incoming meteoroids, most of which break up before they can hit the surface. Near the surface, Earth has an atmosphere that consists of 78 percent nitrogen, 21 percent oxygen, and 1 percent other gases such as argon, carbon dioxide, and neon.

The atmosphere affects Earth's long-term climate and short-term local weather and shields us from much of the harmful radiation coming from the Sun. It also protects us from meteoroids, most of which burn up in the atmosphere, seen as meteors in the night sky, before they can strike the surface as meteorites. Our planet's rapid rotation and molten nickel-iron core give rise to a magnetic field, which the solar wind distorts into a teardrop shape in space. (The solar wind is a stream of charged particles continuously ejected from the Sun.)

When charged particles from the solar wind become trapped in Earth's magnetic field, they collide with air molecules above our planet's magnetic poles. These air molecules then begin to glow and cause aurorae, or the northern and southern lights.   The magnetic field is what causes compass needles to point to the North Pole regardless of which way you turn. But the magnetic polarity of Earth can change, flipping the direction of the magnetic field. The geologic record tells scientists that a magnetic reversal takes place about every 400,000 years on average, but the timing is very irregular. As far as we know, such a magnetic reversal doesn't cause any harm to life on Earth, and a reversal is very unlikely to happen for at least another thousand years. But when it does happen, compass needles are likely to point in many different directions for a few centuries while the switch is being made. And after the switch is completed, they will all point south instead of north.​

Explanation:

Our home planet is the third planet from the Sun, and the only place we know of so far that’s inhabited by living things. While Earth is only the fifth largest planet in the solar system, it is the only world in our solar system with liquid water on the surface. Just slightly larger than nearby Venus, Earth is the biggest of the four planets closest to the Sun, all of which are made of rock and metal. The name Earth is at least 1,000 years old. All of the planets, except for Earth, were named after Greek and Roman gods and goddesses. However, the name Earth is a Germanic word, which simply means “the ground.” Earth is the only planet that has a single moon. Our Moon is the brightest and most familiar object in the night sky. In many ways, the Moon is responsible for making Earth such a great home. It stabilizes our planet's wobble, which has made the climate less variable over thousands of years.

Earth sometimes temporarily hosts orbiting asteroids or large rocks. They are typically trapped by Earth's gravity for a few months or years before returning to an orbit around the Sun. Some asteroids will be in a long “dance” with Earth as both orbit the Sun.

Some moons are bits of rock that were captured by a planet's gravity, but our Moon is likely the result of a collision billions of years ago. When Earth was a young planet, a large chunk of rock smashed into it, displacing a portion of Earth's interior. The resulting chunks clumped together and formed our Moon. With a radius of 1,080 miles (1,738 kilometers), the Moon is the fifth largest moon in our solar system (after Ganymede, Titan, Callisto, and Io).

The Moon is an average of 238,855 miles (384,400 kilometers) away from Earth. That means 30 Earth-sized planets could fit in between Earth and its Moon.

The processes that require additional energy to occur are B, D, and G. When a ball is thrown into the air, energy is required to overcome the force of gravity and to give the ball its kinetic energy.

When KI dissolves in H2O, energy is required to break the bonds between the ions and the water molecules. Similarly, during photosynthesis, green plants use energy from sunlight to convert carbon dioxide and water into glucose. This process is crucial for the survival of plants and other organisms that rely on them for food. Iron metal corrodes over time without requiring additional energy, while the mixing of a small amount of colored gas into a clear container is a spontaneous process that does not require additional energy. Finally, building a car is a human-made process that requires energy input, but it is not a natural process like photosynthesis or the falling of rain.

4. A goiter refers to an abnormal enlargement of the thyroid gland, causing a visible swelling in the neck. It is typically associated with thyroid disorders. A goiter can occur in both hyperthyroidism and hypothyroidism.

In hyperthyroidism, the goiter is usually caused by conditions such as Graves' disease or toxic multinodular goiter. In these cases, the thyroid gland becomes overactive and produces excessive amounts of thyroid hormones, leading to glandular enlargement.

In hypothyroidism, the goiter can develop due to iodine deficiency, Hashimoto's thyroiditis (an autoimmune disease that attacks the thyroid gland), or other factors. In hypothyroidism-related goiters, the thyroid gland may enlarge in an attempt to compensate for the decreased hormone production.

It's worth noting that the presence of a goiter does not necessarily indicate a specific thyroid disorder; rather, it signals an abnormal enlargement of the thyroid gland that requires further evaluation to determine the underlying cause.
