Environmental factors are more likely to affect phenotype than genotype.
Phenotype refers to the observable physical characteristics of an organism, a product of the genetic information contained in the genotype, in accordance with the conditions of the determined environment in which the organism lives.
The phenotype supposes the manifestation of the genotype based on the environmental factors, the traits expressed by the phenotype are behavioral and physical.Regardless of the genotypic information manifested, environmental factors will also shape the phenotype of an organism, since it can suffer accidents, changes or adaptations that a genetically similar individual but in another environment would not suffer.Therefore, we can conclude that the phenotype is the variable expression of a genotype in accordance with the environmental factors.

Which hormone is responsible for the development of the male secondary sex characteristics? estrogen progestin progesterone testosterone.
Answer:
It is Testosterone
Explanation:
The hormone responsible for the development of the male secondary sex characteristics is testosterone. Hence option D is correct.
What is testosterone?Testosterone is a hormone primarily produced in the testes of males and to a lesser extent in the ovaries of females and the adrenal glands of both sexes. It is an androgen, or a hormone that promotes the development of male characteristics.
Testosterone plays a crucial role in the development of male reproductive tissues, such as the testes and prostate, as well as in the growth of muscle mass and bone density.
It is also responsible for the development of secondary sex characteristics in males, such as facial hair growth, a deepening of the voice, and the growth of Adam's apple. Testosterone also regulates sex drive (libido) and sperm production.
In females, testosterone is produced in smaller amounts and helps regulate the menstrual cycle and promote bone density.
An imbalance of testosterone levels in either males or females can lead to various health issues, including infertility, osteoporosis, and disorders of sexual development.
Hence option D testosterone is correct.

soil is the largest terrestrial pool of carbon , containing about 2,200 gigatons. the primary reason that soil is such a large pool of carbon is which of its characteristic?
A) formation from weathering of rocks
B) organic content, including microbes
C) pore spaces allowing the flow of water
D high surface area increasing oxidation
The characteristic of soil that makes it the largest pool of carbon is its organic content, including microbes.
Soil is defined as the outermost portion of the earth's crust on which plants grow. The soil is the part of the earth that supports plant growth because it is rich in nutrients and organic matter.
Plants and animals die and decompose. The carbon content of these organisms are thereby returned to the soil. Also, many microbes are found in soil. Therefore, the characteristic of soil that makes it the largest pool of carbon is its organic content, including microbes.

HELP NEEDED ASAP! 30 POINTS AND BRAINLYEST TO WHOEVER ANSWERS WITH THE BEST ANSWER! What are 3 examples of gene therapies that are used to treat diseases?
Answer:
Viruses used in gene therapy are retroviruses, adenoviruses, adeno-associated virus, herpes simplex, and vaccinia. Retroviruses are most commonly used because they can incorporate their genetic material into the host cell’s DNA, thus changing the genetic component of that cell.
Explanation:
Gene therapy is a medical field which focuses on the genetic modification of cells to produce a therapeutic effect or the treatment of disease by repairing or reconstructing defective genetic material. The first attempt at modifying human DNA was performed in 1980 by Martin Cline, but the first successful nuclear gene transfer in humans, approved by the National Institutes of Health, was performed in May 1989. The first therapeutic use of gene transfer as well as the first direct insertion of human DNA into the nuclear genome was performed by French Anderson in a trial starting in September 1990. It is thought to be able to cure many genetic disorders or treat them over time.

What molecule is the source of information for transcription.
DNA is the molecule, which is the source of information for transcription.
• During the process of transcription, RNA polymerase is an enzyme, which is accountable for copying a sequence of DNA into a sequence of RNA.
• The RNA polymerase monitors the phenomenon of transcription.
• At the time of transcription, the information is stored within a molecule of DNA, which is further copied into a new molecule of messenger RNA.
Thus, the correct answer is DNA.

which of the examples are considered anabolism? select all that apply.
Anabolism is for the synthesis of complex molecules essential in the building up of organs and tissues. It is therefore responsible for the increase in body size. Examples of anabolism are bone growth and mineralization, and muscle mass build-up.
Answer:
DNA nucleotide synthesis or polymerisation or condensation reactions;
Catabolism is breaking down of a larger molecule, so 1 large will become 2 or more smaller molecules;
Anabolism is the opposite, 2 or more smaller molecules will join together to form 1 larger molecules

the major way that meiosis ii differs from mitosis is that
Meiosis and mitosis are forms of cell divisions that occurs in cells in eukaryotes. This forms of division enables growth and development.
The major way meiosis ii differ from mitosis is that in meiosis II, the daughter cells formed are haploid cells.
Mitosis is also termed as an equational division meaning that the end result yields the same number as the beginning, there is no reduction and resulting cells are still diploid.
In meiosis, there is the reduction in half first in meiosis I then the homologous chromosomes separates at the centromeres in meiosis II resulting in haploid cells.
