Can someone explain?

Answer:

Without genetic variation, natural selection is only able to grow the number of allelomorphs that previously exited in the population. Natural selection occurs through an interaction between the environment and the variability of the individual organisms making up a population. If every giraffe had the same neck length, there would be nothing to change and they would never have a long neck by now.

Answer:

Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. ... During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.

Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. ... Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome.

Mitosis is a process where a single cell divides into two identical daughter cells (cell division). During mitosis one cell? divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.

Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.

Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.

Answer:

The allelic frequency for pointed ears is 0.5 (50%).

Explanation:

The frequency of alleles in a population must add up to 1 (100%).

The allelic frequency for pointed ears is 0.5 (50%).

The allele frequency represents the incidence of a gene variant in a population. Alleles are variant forms of a gene that are located at the same position, or genetic locus, on a chromosome.

Gene frequency, which more or less refers to the allele frequency, is the measurement where the number of repeats of the same allele is measured over a certain period of time.

Explanation:

Answer:

This question lacks options, the complete question is: What do you think would have the greatest effect on the body—a harmful mutation in a pluripotent embryonic stem cell, or a harmful mutation in an adult multipotent stem cell?The correct answer is a harmful mutation in a pluripotent embryonic stem cell.

Explanation:

Pluripotent Stem Cells can self-renew and differentiate into any of the three germ layers, which are: the ectoderm, the endoderm and the mesoderm. These three germ layers subsequently differentiate to form all the tissues and organs within a human being. If during embryonic development, genetic mutations - alterations in genes - occur in the embryonic stem cell, they pass to daughter cells as a consequence of cell division, and an individual is generated whose cells differ at the genetic level. Multipotent stem cells are organospecific cells, that is, they can give rise to any type of cells but from a specific organ (a lung, a kidney or the brain). Their differentiation ends the moment they specialize and become a cell with a specific function within a specific tissue or organ. If there were a mutation in these cells, it would damage a specific designed tissue or organ.

Answer:

Sedimentary Rock

Explanation:

Sedimentary rocks are formed from pieces of sediments or other existing organic matter or rock.

The sedimentary rock formation process begins with weathering which involves the breakdown of the sediments into small fragments. The next process is erosion, where water like the Nile River carries them to other places -  in this case, the Ocean.

Over time, the sediments settle and become compressed as more sediments are deposited on top of them.

This leads to the formation of Sedimentary Rocks.

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

Heredity refers to the transfer of traits (specific characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, handedness, freckles, curly hair, color blindness, height, etc.

According to Mendel's Law of Dominance, if a gene has two alleles, there are three (3) possible genotypes.

The three (3) possible genotypes are;

III. A recessive combination such as aa.

Answer:

5 Facts

Explanation:

1. When it comes to chemical weathering, it’s all about chemistry. By looking at the term “chemical weathering,” you can see that a chemical reaction causes something to break down or “weather.” That “something” is rocks and minerals.

2. In chemical weathering, rocks and minerals are reacting to acids, oxygen, carbon and water. That’s why no two rocks ever look exactly the same. It’s also the reason that we have those awesome looking caves and unique rock formations all over the world.

3. While chemical weathering creates nifty formations, the way it breaks down rocks also causes fractures in ancient structures like the Great Sphinx of Egypt. It also causes the surface to break down on gravestones.

4. Chemical weathering types can work separately, but they often work together to create landforms and break down minerals.

5.  Acid rain caused by pollution such as factory and car exhaust is another agent of chemical weathering.
