Answer:

Asthma is a chronic, inflammatory disease of the airways with permanent hypersensitivity. In those with a corresponding disposition (with an overly sensitive bronchial system), the inflammation leads to attacks of breathlessness as a result of acute narrowing of the airways - a so-called bronchial obstruction. This narrowing of the airways is caused by increased secretion of mucus, spasms of the bronchial muscles and the formation of edema of the bronchial mucous membrane; it is reversible through treatment. About 1 of every 10 individuals has or had asthma at least once.

The organisms that feed on dead and decaying matter are called Saprotrophs.

An organism that feeds on dead and decaying organic matter is called a saprotroph. These organisms are heterotrophic, which means that they obtain their food from other sources. They are important in the ecosystem because they break down dead organic matter and recycle it back into the soil, making nutrients available to other living organisms

Answer:

A. Saprotrophs

Explanation:

Saprotrophs are organisms that obtain their nutrients by feeding on dead and decaying matter. They play a crucial role in the ecosystem by decomposing organic material and recycling nutrients back into the environment.

These organisms secrete enzymes that break down complex organic compounds into simpler substances, such as sugars and amino acids, which they can absorb and utilize for their own growth and energy needs. Examples of saprotrophs include fungi (such as mushrooms and molds) and certain bacteria.

Unlike autotrophs, which can produce their own food through photosynthesis or chemosynthesis, saprotrophs rely on external sources of organic matter for their nutrition. They actively decompose dead plants, animals, and other organic materials, aiding in the process of nutrient recycling and decomposition.

Heterotrophs, on the other hand, are a broader category of organisms that obtain their nutrients by consuming other living or dead organisms. This includes saprotrophs, as well as other types of organisms such as herbivores, carnivores, and omnivores.

Parasites, meanwhile, are organisms that live in or on other organisms, known as hosts, and obtain their nutrients from the host while causing harm or damage to it. Unlike saprotrophs, parasites typically rely on a living host for their sustenance rather than feeding on dead and decaying matter.

Continental crust, Oceanic Crust,  Lithospheric Plate The age of material on a tectonic plate depends in part on what type of crust it is composed .

What is Oceanic Crust?

Oceanic crust is the outermost layer of the Earth's lithosphere which forms the ocean floor. It is composed of mafic igneous rocks such as basalt and gabbro. It is typically 5 to 10 km thick and is the youngest layer of the Earth's lithosphere.

Oceanic crust is formed by seafloor spreading at mid-ocean ridges, which occur when two tectonic plates are pulling apart from each other. This causes molten material from the mantle to rise up and cool, forming new oceanic crust. The newly formed crust then moves away from the mid-ocean ridge in both directions, forming a diverging boundary. As it moves away from the ridge, the oceanic crust cools and becomes denser and denser.

Answer:

Here are four traits that would make it hard for a vaccine to be used:

1. Rapid mutation rate. If a pathogen mutates rapidly, it will be able to evade the immune system's defenses, including the antibodies produced by a vaccine. This is a particular problem with viruses, which can mutate very quickly.

2. Ability to evade the immune system. Some pathogens are able to evade the immune system by hiding inside cells or by changing their surface proteins so that they are no longer recognized by the immune system. This makes it difficult for the immune system to mount an effective response to the infection.

3. Ability to spread easily. If a pathogen is easily spread from person to person, it will be more difficult to prevent infection through vaccination. This is a particular problem with respiratory viruses, which can be spread through coughing and sneezing.

4. Lack of animal reservoirs. If a pathogen does not have animal reservoirs, it will be more difficult to develop a vaccine against it. This is because vaccines are typically developed using weakened or killed versions of the pathogen. If there are no animal reservoirs, there will be no source of the pathogen to use for vaccine development.

It is important to note that these are just a few of the traits that can make it difficult to develop a vaccine against a pathogen. There are many other factors that can contribute to the difficulty of vaccine development, such as the cost of vaccine development, the availability of funding, and the political will to support vaccine development.

Answer

A. The decrease in predators will cause prey populations to

increase rapidly, disrupting both biotic and abiotic factors

in the ecosystem.

Explanation

If the keystone predator is removed, no other species would be able to fill its ecological niche. The ecosystem would be forced to radically change, allowing new and possibly invasive species to populate the habitat. A keystone species that is a predator controls the herbivore populations, which in turn maintains the plant populations and keeps balance.

Although removal of a keystone species will alter the food web on an ecosystem, some parts will persist.

Most articles pass right through the atom, this means that most of the atom is an empty space.

An atom is described as a particle that consists of a nucleus of protons and neutrons surrounded by a cloud of electrons.

Protons and neutrons make up the core nucleus of an atom, which is encircled by an electron cloud. In relation to the size of the atom as a whole, the nucleus is exceedingly small.

As a result, the electrons surrounding the nucleus are the primary target of interactions when particles or even light pass through an atom. The majority of the atom's remaining space, which includes the nucleus, is vacant.

You will find the model of the cell cycle in the attached files

Answer:

A. Arrow 1 represents interphase, and Arrow 2 represents mitosis.

Explanation:

When we talk about the cell cycle, we refer to the interphase and the cell division (mitosis or meiosis).

Interphase: Represented by arrow 1.

The interphase is the previous step before mitosis occurs. The interphase is conformed of the G1, S, and G2 stages.

• During the G1 stage, it occurs a high intense biochemical activity. The cell duplicates its size, and the organelles and other molecules and cytoplasmatic structures also double. Some structures, such as microtubules and actin filaments, are synthesized from zero. The endoplasmic reticulum increases in size and produces a membrane for the Golgi complex and vacuoles, lysosomes, and vesicles. During this stage, the pair of centrioles separate, and each centriole duplicates. Mitochondria and chloroplasts also replicate.

• During the S stage, the DNI replication process occurs. This is the only stage in which the DNI molecule replicates. The synthesis of histones and other associated proteins also occurs.

• G2 stage is the interphase last step. DNI molecule begins to slowly condensate. The centrioles duplication process completes. The spindle fibers get assembled.

Once the whole interphase is completed, mitosis occurs.

Mitosis: Represented in the cycle by arrow 2.

Mitosis is a process by which, from a diploid somatic cell (2n), two daughter diploid cells (2n) are produced. During mitosis, the whole-cell first duplicates and then separates. Mitosis is divided into four phases (these phases are shown in the cycle with different gray color tones). During prophase, chromosomes condensate, and the nuclear membrane breaks. During the metaphase, fibers of the spindle apparatus take chromosomes toward the equatorial cell plane, where they line up. Sister chromatids are holden together until they reach the Anaphase, during which specialized enzymes break the bonds between chromatids and separate them. Each chromatid migrates to one of the poles. In telophase, the new chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole. Finally, cytokinesis occurs.

Drop each ball from the platform three more times . Reliability or precision means how much the measured values vary from each other when measured by performing the same experiment repeatedly.  When measuring values by observation in physical experiments of this nature, it is best to perform the experiment and measure the values at least three times. The more the better.  In such measurements there is always a margin of error, e.g., how at exact time you start and stop the stopwatch. There may also be a bit harder or softer side of ball (tennis ball strip) touching the ground. In order to minimize such and some other margin of errors, it is advisable to measure the values more than 3-4 times, and then take their mean. The value now obtained would be would reliable or precise.  Second and third options are incorrect because they will have no effect on improving the reliability.  In order for the fourth option to be correct, the other people need to do the same (not similar) experiment, with the same balls and same conditions/instruments. That would be equivalent to repeating the experiment 3-4 times, which is already covered by first option.

Answer: the development of the enzyme Rubisco and evolution of oxygenic photosynthesis.

Explanation: One can pick many key steps in early evolution: the development of the first cells, oxygenic photosynthesis, endosymbiosis leading to eukaryote organisms.

One important step was the mutation to the enzyme ribulose bisphospate carboxylase oxygenase (Rubisco) which enabled oxygenic photosynthesis.

The cyanobacteria that had Rubisco changed the planet’s atmosphere by producing oxygen as a by-product of photosynthesis. They were the most successful organisms of the time and have continued as a successful and ubiquitous group of organisms for billions of years.

The production of oxygen changed the direction of evolution profoundly. Later endosymbiosis led to the evolution of plants, with cyanobacteria the ancestors of chloroplasts, making Rubisco one of the most common enzymes on the planet.

DNA is composed of two strands of nucleotides. The bases of these nucleotides form pairs: Adenine with thymine and cytosine with guanine. The complementary strand is 3' - GCTAATCA - 5' .

DNA is the molecule in charge of carrying genetic information needed for the correct cell functioning.

This polymer is composed of several monomers joined by their extremes. Each monomer has a phosphate group, a sugar, and a base (adenine, guanine, thymine, or cytosine).

DNA is composed of a double, coiled monomeric strand. One of the strand's bases pairs the bases of the other strand (adenine must always pair thymine, while guanine must pair cytosine).

These strands are known as the coding strand and the template strand. During DNA replication, the molecule unwinds to separate the strands, and two new chains are synthesized.

So, what we need to know to answer this question is that bases pairing is as follows,

Adenine (A) ⇔ Thymine (T)

Guanine (G) ⇔ Cytosine (C)

Answer:

1. ATP

2. Inorganic phosphate (Pi)

Explanation:

Adenosine triphosphate (ATP) is the usable form of energy by the cells of living organisms. During the light reaction of photosynthesis, energy from sunlight (solar energy) is converted to ATP in order to power the Calvin cycle stage. Also during cellular respiration, energy stored in glucose molecule is transferred to ATP.

The processes by which this synthesis of ATP from ADP (Adenosine diphosphate) occurs is called oxidative phosphorylation and chemiosmosis. Energy is stored in the ATP molecule when ADP combines with inorganic phosphate (Pi).

The best summary of the outcome of Redi's experiment is that the experiment provided evidence against spontaneous generation by demonstrating that maggots do not spontaneously generate from decaying meat when it is isolated from flies.

Francesco Redi conducted an experiment in the 17th century to challenge the prevailing belief in spontaneous generation, which proposed that living organisms could arise spontaneously from non-living matter.

In his experiment, Redi set up two groups of jars containing meat. One group was covered with gauze to prevent flies from accessing the meat, while the other group was left uncovered.

Over time, Redi observed that maggots appeared only in the uncovered jars where flies had access to the meat, while the covered jars remained free of maggots.

This led Redi to conclude that maggots were the offspring of flies and did not arise spontaneously from the meat.

His experiment provided empirical evidence against the theory of spontaneous generation and contributed to the development of the concept of biogenesis, which states that living organisms come from pre-existing living organisms.
