PLEASE ANSWER QUICK>>>>>Explain how enherited traits are determined
Answer:An inherited trait is one that is genetically determined. Inherited traits are passed from parent to offspring according to the rules of Mendelian genetics. Most traits are not strictly determined by genes, but rather are influenced by both genes and environment.

A student is presented with a model of a digestive system and is asked to remove one structure (small or large organ) that will have the largest impact on decreasing chemical digestion. Which structure should the student remove
Answer:
Small intestine
Explanation:
Digestion is the process of breaking down food molecules into simpler and usable forms by the body cells. The process of digestion involved the mechanical aspect and chemical aspect. The mechanical one deals with using physical means like chewing to break down the food particles.
However, the chemical one deals with the usage of chemically-secreted enzymes to work on the food molecules. Lots of digestive organs are involved in this chemical digestion, but, the most of chemical digestion takes place in the SMALL INTESTINE. The small intestine is where most of the chemical digestion occurs including absorption.
Hence, according to this question, the student should remove the SMALL INTESTINE because it will have the largest impact on decreasing chemical digestion.

1. What is the overall purpose of mitosis and meiosis?
2. Why is it important that DNA is replicated prior to cell division?
3. How are normal cells and cancer cells different from each other?
4. Describe mistakes that can occur during the cell cycle and cause human disorders.
Mitosis aims to create daughter cells that are completely genetically similar to their mothers, with no extra or less chromosomes. In contrast, meiosis serves a single function in the human body that is the creation of gametes.
What is cell division?The process by which a parent cell divides into two daughter cells is known as cell division. Cell growth and chromosome replication precede cell division, which often happens as part of a longer cell cycle.
Before dividing, cells must copy their DNA. This promotes successful inheritance of genetic features by giving each daughter cell a copy of the genome.
Grow in the absence of signals instructing them to do so in cancer cells. Only when they get such signals do normal cells expand. Disregard cues that would typically instruct cells to cease dividing or die.
Aneuploidy is a condition when there are either too many or too few chromosomes in the daughter cells produced during mitosis.
Thus, this is the overall purpose of mitosis and meiosis.

1. The overarching goal of mitosis is to ensure cell division and the transfer of genetic material to daughter cells for tissue repair, growth and development.
2. To maintain genetic integrity, DNA replication is necessary prior to cell division.
3. Cancer cells have uncontrolled growth, escape cell death and lack contact inhibition, whereas normal cells have controlled cell division, experience programmed cell death and show contact inhibition.
4. The disorders in humans can result from errors in the cell cycle. Diseases such as Down syndrome are caused by abnormal chromosomes. Gene changes can affect the development of cancer.
Meiosis produces gametes for sexual reproduction, while mitosis assures cell division for growth, development, and tissue repair. Accurate transmission of genetic information and preservation of genetic integrity in daughter cells depend on DNA replication prior to cell division.
Whereas cancer cells have uncontrolled proliferation, escape from cell death, and lack contact inhibition, normal cells have regulated division, programmed cell death, and appear to have contact inhibition. Human disorders such as chromosomal abnormalities (such as Down syndrome), gene mutations that cause cancer, errors in DNA replication or repair that cause genetic disorders, and cell cycle control that leads to uncontrolled cell division and tumor formation, all of which Mistakes made during this can have consequences. cell cycle.

Explanation:
Why does the body produce more urine on a cold day rather than a hot day if the same amount of
water is consumed?
Explanation:
During summer when the surrounding temperature is high, we lose water in the form of sweat, direct evaporation considerably. Hence kidneys retain water for maintaining fluidity of the blood and less urine is formed.
But during winter, the surrounding temperature will be very low. There will not be any sweating, no evaporation losses. Moreover to keep the body temperature constant, the blood capillaries in the skin get constricted and the blood pressure is increased. The result is that our body gets warmed up. In order to maintain the blood pressure normal, the excess water along with the wastes is excreted mostly in the form of urine. This is the reason for more urine out put and frequent urination under very cool conditions and in winter.
Describe the movement of water if cells are in a hypertonic solution, hypotonic solution, and isotonic solution.

Explanation:
In silkworms,yellow cocoon (B) is dominat over white cocoon(b). If the mom is BB and the dad is bb, what are the chances they have offspring with yellow cocoons?
Answer:
100 %
Explanation:
Dominance is a genetic phenomenon where a gene variant or allele masks the effects of another allele (of the same gene) in heterozygous individuals. This last gene variant is referred to as the recessive allele. In this case, the silkworm mother can produce only one type of gamete carrying the dominant gene (B) form, while the silkworm father can produce only one type of gamete carrying the recessive gene (b) form. In consequence, from this cross, all offspring (100 %) will be heterozygous (Bb) and therefore they will express the dominant trait (i.e., yellow cocoon).

Which of the following characteristics of a population will make it better able to adapt to environmental changes?
A.Rapid production of many offspring.
B.Specialization in one type of food source.
C.Large amount of inherited genetic variation.
D.Isolation to a limited geographic range.
Answer:
C
Explanation:
Answer: C. Large amount of inherited genetic variation.
If you had a population where the genetic variation wasn't as high or practically non-existent, then that population is likely suited to that very narrow specific environment. If the environment doesn't change, then the population wouldn't have a problem. However, the environment isn't likely to stay static. Things change all the time and this change will bring challenges to the population that was suited for the old environmental conditions.
Populations with high genetic variability will have some individuals thrive while some unfortunate members will perish. The members that die off are likely the ones who cannot adapt to the changes. As the environment changes, the individuals who survive will pass on their DNA to their offspring, allowing for natural selection to reinforce those favorable traits. Since the environment is constantly changing, whether that change is slow or fast, this means the process is continued indefinitely. So that's why high genetic variability is favored.

Some genes are important enough to be called "molecular switch" or "master" genes. What is the purpose of these genes?
A. They control when other genes are expressed
B. They determine the organization of the genome
C. They regulate cell metabolism
D. They modulate the rate of translation
Answer:
Genes called "molecular switch" or master genes have the purpose of control when other genes are expressed (option A).
Explanation:
Master gene is so named because it has the function of controlling the behavior of other genes, organizing their functions and regulating when they can be expressed.
The name of molecular switch is synonymous with the master gene, since its activation determines the genetic regulation necessary to establish cell differentiation and even the determination of the sex of some species.
The other options are not correct because:
B. Master genes do not determine the organization of the genome .
C. Regulation of cell metabolism depends of substances as hormones and enzymes.
D. The rate of translation does not depend on the activity of master genes.
