Answer:

Arthropods make up almost 80% of all animals; they are jointed legged animals that belong to the Animalia kingdom that include centipedes, millipedes, insects, and spiders. The success of arthropods can mainly be attributed by the following characteristics;

Presence of Exoskeleton.

The presence of exoskeleton that hardens due to the presence of chitin offers a protective cover for arthropods with different environment against advance conditions and also it protects against dehydration.

Varied habitats.

Arthropods can be found in all types of habitats from the soil, water, and land. This feature is the key to their survival since they are widely distributed hence increasing chances of survival.

Bilateral Symmetry.

Arthropods exhibit bilateral symmetry whereby a different portion of their bodies are mirror images, this form is exhibited in higher animals such as humans and dogs, and it facilitates advanced body functioning.

Jointed Legs.

Arthropods exhibit segmented legs that are jointed to allow the development of hard exoskeleton for protection. The jointed legs are specialized for grasping, jumping and running.

Short generation time.

Arthropods exhibit short generation time, which allows for faster adaptation to the environment and survival.

Reproduction strategy.

Arthropods have exhibited a sexual form of reproduction that is more successful in the growth and survival of offspring.

Segmented body.

Arthropods have a segmented body that allows for specialization of body organs and tissues, and this has promoted their success by specializing body organs to different functions.

The result of mitosis is two identical daughter cells, genetically identical to the original cell, all having 2N chromosomes. ... A chromatid, then, is a single chromosomal DNA molecule. In contrast to a mitotic division, which yields two identical diploid daughter cells, the end result of meiosis is haploid daughter cells with chromosomal combinations different from those originally present in the parent. In sperm cells, four haploid gametes are produced.

Explanation:

Biodiversity can be regarded as biological variety as well as variability of life on the Earth. It can be explained as term that gives measurement of variation, as regards to level of species,

ecosystem as well as genetic. Example of biodiversity can be found in ocean whereby different varieties as well as different types of animals and plants live in a particular ocean. It should be noted that biodiversity is defined as the diversity of forms of life in an area and within a species; not equivalent to the number of species.

Answer:

3.1.1 Division of the cytoplasm - Cytokinesis

3.1.2 Uncontrolled cell growth - Cancer

3.1.3 Chromatids lined up at equator of cell - Metaphase

3.1.4 Chromatids joined at this point - Centromere

3.1.5 Mass of cancerous cells - Tumor

3.1.6 Skin cancer - Carcinoma

3.1.7 Growth and mitosis - Meristematic

3.1.8 Cancer causing factors - Carcinogens

3.1.9 Cancer cells that do not spread - Benign

3.1.10 Replicated half of a chromosome - Chromatid

Explanation:

The division of the cytoplasm is known as Cytokinesis. It occurs during the later part of the division of the nucleus in both mitosis and meiosis. In Cytokinesis, the cytoplasm of a single parent cell divides in two to produce two daughter cells.

Cancer is a disease condition that results when the growth and division of cells is uncontrolled. It occurs as a result of changes to the DNA either due to environmental factors or heredity factors.

Metaphase is one of the four stages in mitosis. During mitosis, the chromatids which are joined at the centelomere line up at the middle or equator of the cell.

Centromere is a region in the chromosome in which sister chromatids are joined together to form a short and a long arm of the chromosome.

A tumour is a swelling of a part of the body due to the abnormal growth of cells in that part of the body. A tumour may have the ability to spread or not.

Cancers that originate in the skin or tissues lining organs is known as carcinomas.

In plants, meristematic tissues are responsible for growth as they consist of actively dividing or mitotic cells. Meristematic cells are present at the tips of roots,stem and branches.

Carcinogens are agents or factors that are able to cause cancers. They include such agents like chemicals, electromagnetic radiations, some viruses, lifestyle factors, etc.

Benign tumours refers to growths in tissues or organs of the body which are non-cancerous as they do not spread to other tissues or organs in the body.

A chromatid is one-half of a replicated chromosome present in the nucleus of the cell. Two chromatids are joined together at the centromere to form the chromosome.

Answer:

67%

Explanation:

When taking random samples from a population, the observed numbers are not always as the expected ones. The difference is by chance, instead of 50% heter0zyg0us, the sample included 67%.  

--------------------------

Available data:

-  Moths' color ⇒ diallelic gene

- f(G) 1960 = 0.8

- f(G) 1965 = 0.7

- f(G) 1970 = 0.6

- f(G) 1975 and 1980 = 0.5

-  1980 ⇒ N = 2000 pupae

-  Population in H-W equilibrium

Hardy-Weinberr equilibrium,  

In this problem we assume that the population is under H-W equilibrium, and we know that p = 0.5.

Considering that p + q = 1, then by clearing the equation, we get the value of q = 0.5    

Finally, we know that the genotypic frequency of the heter0zygous genotype is 2pq, so,

F(Gg) = 2pq = 2 x 0.5 x 0.5 = 0.5 = 50%

Now, among the options in the problem, there is not 50% but others. One of them, and the closest to 50%, is 67%.

The chart reflects that through the years, the moth's populations stabilized. Both alleles were favored, and their frequencies got to be equal to each other -0.5-. So there is a high probability of getting heter0zyg0us individuals in the population -50%-, more than any of the h0mzyg0us ones -25%-.  

However, in a natural population, the amount of h0m0zyg0us and heter0zygous individuals observed is not always the same as the expected ones. This fact happens especially when there are random samples.

In this experiment, the researcher took 2000 pupae, but they did not know their genotype. They just took them randomly. Even though the population is in H-W equilibrium, when sampling, the researcher took more heter0zyg0us individuals than the expected ones. It does not mean that the population is not under H-W equilibrium. It just means that by chance, more heter0zyg0us were selected.

So what you need to do in these situations, is to analyze your problem and the provided information, and think about the most feasible answer.

In this case, the expected number is 50% heter0zyg0us. The closest option is 67% and the most feasible. So that would be the answer.

Answer:

The brain controls what you think and feel, how you learn and remember, and the way you move and talk. But it also controls things you're less aware of — like the beating of your heart and the digestion of your food.

Think of the brain as a central computer that controls all the body's functions. The rest of the nervous system is like a network that relays messages back and forth from the brain to different parts of the body. It does this via the spinal cord, which runs from the brain down through the back. It contains threadlike nerves that branch out to every organ and body part.

Explanation:

If you brain does not, or is unable to perform multiple tasks automatically, you could have trouble breathing on your own, your heart could have problems, even your thought process, movement, and digestion could malfunction. Which could cause a multitude of complications.
