Answer:

C. 1 and 2 only

Explanation:

Volcano and geyser is not a geologic indicator of building geothermal power plant, hence option C. I and II only is correct.

Geothermal power plants rely on heat that resides a few kilometers beneath the surface of the Earth to collect enough energy to generate electricity.

The heat may naturally exist underground in some places as pockets of steam or hot water. But in order to generate steam, the majority of places need to be "enriched" with water injection.

By boring deep wells into the earth and bringing hot water or steam to the surface, people can make use of these resources. An electric turbine is propelled by hot water or steam.

Therefore, some geothermal wells reach a depth of up to two miles. To turn generator turbines, dry steam plants employ steam that is extracted directly from geothermal reservoirs.

A gamete is a haploid germinal cell that fertilizes to produce a zygote. It contains only one copy of the chromosomes in the form of the allele. Thus, option C is correct.

An allele is a variety or the alternative of the part of the gene that is said to be get inherited by the progenies from the parent cells through the process of reproduction and fertilization.

The allele carries half the copy of the genetic material and is haploid as they result from the meiotic cell division that occurs in the reproductive or the germinal cells of the males and the females.

The meiotic division reduces the number of chromosomes in the daughter cells that combine with the other half of the other gamete to produce a diploid zygote.

Therefore, the version of the trait in the gamete is an allele.

Over a 1/3 of the air was oxygen in the Carboniferous.

During the Carboniferous period, which lasted from approximately 359 to 299 million years ago, the Earth experienced high levels of atmospheric oxygen. The lush vegetation that thrived during this period played a crucial role in increasing oxygen levels through photosynthesis, as plants release oxygen as a byproduct. The accumulation of plant material, particularly large forests of ferns, horsetails, and early trees, led to the formation of extensive coal deposits that we see today.

The high oxygen content in the atmosphere during the Carboniferous had significant impacts on both terrestrial and aquatic ecosystems. It provided an environment conducive to the evolution of a diverse range of organisms, including giant insects and early amphibians. The availability of oxygen also supported the development of larger body sizes, such as the presence of extra-large embryos in some marine organisms adapted to deep ocean depths.

Furthermore, the higher oxygen levels likely influenced the evolution of certain reproductive adaptations in various species. For example, the development of hard casing in eggs allowed them to be laid on land, providing protection and preventing desiccation. Soft-shelled eggs under intense water pressure may have been advantageous for organisms adapted to the depths of the ocean.

Overall, the elevated oxygen levels in the Carboniferous had profound effects on the ecology and evolutionary history of life, shaping the characteristics and adaptations of organisms during this time.

Explanation:

The second order neurons in the spinothalamic tract decussate from the posterior horn of the spinal cord.

In the spinothalamic tract, the second order neurons decussate from the posterior horn of the spinal cord. This occurs at the level of the spinal cord where the second order neurons of the spinothalamic tract cross from the contralateral side to the ipsilateral side of the cord. This decussation occurs in the anterior white commissure, which is a bundle of nerve fibers located in the anterior portion of the spinal cord. The axons of the second order neurons travel up the contralateral side of the spinal cord, forming the spinothalamic tract. This tract carries information from the body to the thalamus, where the information is further processed and sent to the cortex.

A neuron is a specialized cell that transmits information throughout the body. Neurons are found in the brain, spinal cord, and other parts of the nervous system. They are responsible for processing and transmitting signals between the body and the brain. Neurons are made up of dendrites, a cell body, and axons. Dendrites are branches of the neuron that receive signals from other neurons. The cell body contains the nucleus and is the control center of the neuron. Axons are the output of the neuron, sending signals to other neurons. Neurons communicate with each other through chemical and electrical signals. These signals are passed from one neuron to another through synapses.

Answer:

first quarter and neap tide

Explanation:

Answer: Biomagnification refers to the process by which the concentration of a contaminant increases as you move to higher trophic levels in a food chain or food web. In other words, as organisms consume other organisms, the contaminants present in the prey accumulate and become more concentrated in the bodies of the predators.

To understand this process, let's consider an example involving a water ecosystem. Suppose a pollutant is released into the water, such as a pesticide or heavy metal. The primary producers, such as algae or aquatic plants, absorb small amounts of the contaminant from the water. As herbivorous organisms consume these primary producers, they ingest the contaminants along with their food.

Since the contaminant is not easily broken down or eliminated from the organisms' bodies, it accumulates over time. As a result, the concentration of the contaminant becomes higher in the herbivores than in the primary producers. Now, when carnivorous organisms consume the herbivores, they not only accumulate the contaminant from their own food but also from all the prey they have consumed. This leads to an even higher concentration of the contaminant in the carnivores.

Therefore, biomagnification describes the phenomenon where the concentration of a contaminant increases significantly as you move up the food chain or trophic levels. The highest concentration of contaminants is often found in top predators, such as large fish, birds of prey, or mammals, which can have adverse effects on their health and reproductive capabilities.

It's important to note that biomagnification primarily occurs for persistent and non-biodegradable contaminants that cannot be easily metabolized or excreted by organisms. These contaminants are often lipophilic (fat-soluble), which allows them to accumulate in fatty tissues and remain in the organism's body for long periods, leading to biomagnification.

Explanation:

 options a, b, and c are not accurate conclusions based on the given information.

The correct answer is d) They will be haploid (2n). Gametes are haploid cells, meaning they contain half the number of chromosomes as somatic cells. Since the insect's gamete contains 4 chromosomes, the somatic cells would have a diploid number of 8 chromosomes (2n = 8). The amount of DNA in the gamete is not necessarily indicative of the amount of DNA in the somatic cells, as somatic cells can undergo DNA replication and have varying amounts of DNA depending on the stage of the cell cycle.

Natural selection is the process by which organisms that possess favorable qualities are more likely to endure and reproduce, passing those traits on to their progeny. Natural selection can cause changes in the qualities and characteristics of a population over time. New species may eventually arise as a result of these changes.

Anatomical features with a similar function but a distinct evolutionary origin is referred to as analogous structures. These features have independently developed in many lineages, frequently in response to similar selection pressures or environmental constraints. As an illustration, the wings of birds and bats are homologous structures since they both serve the same purpose (flying), although having different evolutionary origins.

When you put water in a glass, it stays there until you tip the glass. (Cohesion)Cohesion is an intermolecular force that causes similar molecules to stick together. The molecules in a glass of water are cohesive, which means they stick together. Water molecules like to be close together and the forces of cohesion draw them together into a spherical shape.2. Rain collects on a leaf instead of running off. (Adhesion)Adhesion is a type of attraction between molecules that causes them to stick together. Water molecules adhere to the surfaces of objects that are more polar than themselves. Leaves, for example, have a high degree of polarity, which allows water molecules to adhere to them.3. Water forms a dome shape when it is on a surface. (Surface tension)Surface tension is the property of the surface of a liquid that allows it to resist an external force. Water molecules at the surface of a liquid are more strongly attracted to each other than to air molecules, causing the surface of the liquid to be more stable.

Explanation:

Demography is usually defined as the science of vital and social statistics, as of births, deaths, diseases, marriages etc. of populations.

This means that a demographer study both birth and death rates as they focus on human characteristics.

In demography, fertility is the birthrate of a population. Or in other words, the ability to produce offspring in a population. Mortality is the opposite of fertility; the death rate of a population. Both of these things are something that a demographer would study as they relate to the continuation of human society. Migration though, is a demographic process in which people migrate between different locations or places, resulting in a contribution to a population. So to explain the demographic terms, international migration takes an impact on a population with its age and size structure resulting in an indirect influence on the rate of future births in a population. This means that a overall, fertility, mortality, and migration all are therefore things that a demographer would study.
