Explanation:

The diagram below shows a portion of a chromosome during meiosis. Meiosis is a process of cellular division that produces haploid gametes from diploid cells. The process of meiosis involves two rounds of nuclear division.

During the first round, homologous chromosomes pair up and exchange genetic material. This process is known as crossing over.

The diagram below shows a section of the chromosome during the first meiotic division. The chromosome is composed of two sister chromatids, which are identical copies of each other.

These sister chromatids are held together by a centromere. At this stage, the sister chromatids are in the process of separating from each other. The arrows indicate the direction of movement of the chromatids as they separate. The diagram also shows a section of the chromosome where the two sister chromatids have already separated.

This section is known as a chiasma, and it is the result of crossing over. During crossing over, segments of DNA from the two homologous chromosomes exchange places. This process creates genetic variation in the gametes, which is important for evolution.

In conclusion, the diagram shows sister chromatids separating, alleles independently assorting, segments of DNA crossing over, but not genes replicating. The correct answer is A. Sister chromatids are separating.

Answer:

Parasitism

Explanation:

Example: Mosquitoes feed off the blood of a human and is benefitted, the human is harmed because the mosquitoe exposed he/she to malaria.

A symbiotic relationship in which one species benefits and the other is harmed is called parasitism. The parasite lives on the food of the host. Fourth option is correct.

In symbiosis, two organisms are present in close contact. There are different types of relationships seen in nature, such as mutualism, commensalism, parasitism, etc.

Mutualism occurs when two organisms, such as lichen, benefit from one another. Lichen is an association of algae and fungi. Algae makes food that is consumed by fungi, and fungi provide algae for a place to live.

In parasitism, one is the host, and the other is the parasite. An example is the tapeworm in the human intestine. Tape worms consume digested human food and harm humans by spreading their population. Here, the host is negatively impacted by the presence of parasites.

In predation, both are harmed as both are involved in the fighting. In commensalism, one party gets benefits while the other is not harmed by the association.

Hence, the fourth option is the correct answer, which is parasitism.

Answer:

The correct answer is -

Adult body symmetry

The embryological formation of body cavities

Gene sequences

The number of tissue layers

Explanation:

Scientists and taxonomists use different criteria to assign different animals to particular phyla. The various systematic criteria that are used more frequently by systematists are as follows:

1. Adult body symmetry

Body symmetry is one of the criteria used to assign an organism or animal to a particular phylum. There is two symmetry found in animals radial and bilateral.  If any plane passes through the middle axis and divides into two identical segments called radial symmetry and Bilateral symmetry is where only a single plane divides the body into halves. However, there are many animals that do not have any symmetry and called assymetrical.

2. The embryological formation of body cavities

Other than layers body cavities also helps in assigning the animals that depend on coelom -  body cavity between the body wall and gut wall

Animals could be - coelomate(coelom present), pseudocoelomate -(not lined with mesoderm) and acoelomate(coelom absent).

Gene sequences

Genetic similarities also consider and how close an organism to their organism of the phylum or species.

 The number of tissue layers

Different body parts, tissues, muscles, and organs developed from the different cell layers that are formed during embryo, therefore, called embryonic layers.

Animals on the basis of these embryonic layers could be diploblastic or triploblastic. Diploblastic animals form 2 embryonic layers the outer and inner layers called the ectoderm and the endoderm respectively. Triploblastic animals have an extra middle layer known mesoderm.

Answer:

Reproduction, heredity, variation in fitness or organisms.

Explanation:

Evolution occurs in organisms due to natural selection process because natural resources are limited. Evolution is the change in the characteristics of a species over several generations. If evolution occurs in the organisms so these evoluted organisms can survive rate more than those organisms where no evolution occurs because the evoluted organisms can adopt successfully the features of environment. Reproduction, heredity, variation in fitness or organisms are the four factors needed for natural selection to act.

Answer:

Meiosis also produces genetic variation by way of the process of recombination. Later, this variation is increased even further when two gametes unite during fertilization, thereby creating offspring with unique combinations of DNA.

Exponential growth is a type of population growth pattern in which a population size increases at an accelerating rate, with each generation or time period adding a larger number of individuals than the one before it. This type of growth results in a population having a higher total number of members than it did in the previous generation.

To put it another way, the rate of population growth picks up steam over the course of time, producing a J-shaped curve when the data is plotted on a graph. This pattern can emerge when there is an abundance of resources available to a population but only a moderate amount of competition for those resources. This results in rapid reproduction and population growth as a result.

Hello. You have not shown the neighborhoods to which the question relates, which makes it impossible for your question to be answered accurately. However, I will try to help you in the best possible way.

The best way to reduce spending on carbon dioxide and increase biodiversity in a neighborhood is to provide tree planting through urban afforestation. A well-wooded neighborhood, it has a lower concentration of carbon dioxide because the plants absorb this gas releasing oxygen in place. In addition, some animals such as birds would attract them, in addition to promoting fruit and shade for the neighborhood.

Answer:

The most ideal way to lessen spending on carbon dioxide and increment biodiversity in an area is to give tree establishing through metropolitan afforestation. A well-lush area, it has a lower centralization of carbon dioxide in light of the fact that the plants assimilate this gas delivering oxygen set up. Likewise, a few creatures, for example, birds would draw in them, as well as advancing products of the soil for the area.

Secondary succession.

Explanation:

Clearcutting leaves an area barren. It is a  horrible practice and is opposed by every environmental group. There are better ways of logging without destroying the plant life present there.  This is secondary succession because plant life did exist in the area that clear cut and will again if the logging company or the government will replant the area.

Multicellular is a cellular classification where the organism is made of more than one cell. The multicellular organism that absorbs nutrients best fits in the kingdom of Fungi. Thus, option C is correct.

Fungi is one of the five kingdoms that are characterized by eukaryotic organisms with multicellular structures. They contain microorganisms that are heterotrophs and cannot make their own food. They absorb the nutrients from decaying organic materials.

The fungal mycelia and filaments called hyphae allow fungi like mushrooms and molds to absorb nutrients and minerals from the surrounding. They digest the nutrients with the help of enzymes.

Answer:

Miller and Urey's research showed that it was possible for organic molecules to be developed from inorganic molecules, which contributed to the hypotheses about the origin of the earth.

Explanation:

Stanley L. Miller and Harold C. Urey developed a series of research and experiments that showed that the planet earth, even in its primitive state, promoted a series of chemical reactions that used inorganic substances as a reagent, to create organic substances as a product and these organic compounds were the precursors of life on earth.

To reach this conclusion, they used a closed system, without the presence of oxygen, but with the presence of hydrogen, ammonia, methane and water vapor. They subjected this system to various cycles of electrical discharges, heating and condensation of the page, to create environments in which chemical reactions could happen. After some time, it was possible to observe the presence of organic molecules.
