what do you think causes different phenotypes in organisms how does the phenotype depend on its genes (genotype)​

Answers

Answer:

They difference in phenotypes is dependent on the genes. The more dominant gene will overpower a recessive gene, or if there are two recessive genes together, that will be the phenotype. When things are cross breaded they introduce different genotypes that allow for different looking phenotypes.

Example: Dominant blue flower (Bb)  mixed with recessive yellow flower (bb)

        B            b

b       Bb          bb

b       Bb          bb

There is a 50/50 chance the offspring will be either blue or yellow

The differences in phenotypes are determined by genes. The more dominant gene will completely overwhelm a recessive gene, or if two recessive genes coexist, the phenotype will be that. When things are crossbred, unique genotypes are introduced, allowing for different-looking phenotypes.

What is phenotype?

A "phenotype" is simply an observable trait. "Pheno" simply means "observe," and it derives from the same root as "phenomenon."

The differences in phenotypes are determined by genes. The more dominant gene will completely overwhelm a recessive gene, or if two recessive genes coexist, the phenotype will be that.

When things are crossbred, unique genotypes are introduced, allowing for different-looking phenotypes.

Thus, in this way, phenotype is dependent on genotype of the organism.

Which of the following shows a correct base pairing in DNA?
A and G
T and G
C and A
Gand C

Answers

I think it is G and C

Answer: G and C

Explanation:  DNA carries the hereditary information for organisms. W ithout DNA, our species would be unable to pass traits from generation to generation. DNA controls all aspects of an organism. It tells spiders how to spin webs, birds to lay eggs, and what color to make your eyes. The genetic information in DNA is stored as special chemical sequences, called chemical bases. The chemicals bases are adenine (A), guanine (G), cytosine (C), and thymine (T). Each base connects with another to form base pairs. Adenine always pairs up with thymine. Cytosine always pairs up with guanine

Recall what you know about nervous tissue to answer the following questions. Nervous tissue can generate and conduct ____ signals that control the body.
answer choices are:
chemical
electrical
thermal

Answers

Answer:

Nervous tissue can generate and conduct electrical signals that control the body.

Explanation:

The neuron is the specialized cell that provides function to nerve tissue. Given the structure of the neuron, this cell is capable of creating and conducting information in the form of electrical impulses or signals, by depolarizing its cell membrane and generating action potentials.

The information generated and transmitted by the neurons allows the nervous system to obtain internal and external information of the organism, as well as to control all the body functions.

    The other options are not true because nerve tissue does not generate or conduct thermal or chemical signals to perform its function.

Answers

Answer:

C. The salt is dissolved by the water

Explanation:

When ionic compounds dissolve in water, the individual ions separate and get surrounded by water molecules—a process called solvation. Because the salt ions are charged, they dissolve much better in a polar solvent, which is also slightly more charged than a nonpolar solvent

how do skin cells replace itself after an injury?

a) skin cells go through the process of budding to make new identical cells.
b) skin cells go through the procces of mitosis to make new identical cells.
c) skin cells go through the process og photosynthesis to make new identical cells.
d) skin cells go through the process of cellular respiration to make new identical cells.

Answers

Answer:

d

Explanation:

as a result of accumulation of waste products in the body , these substances are removed from the body via the skin hence they undergo cellular respiration

Answer:

b) skin cells go through the process of mitosis to make new identical cells.

Explanation:

The skin is the largest organ in the human body; it forms a protective barrier that keeps out external pathogens, and is integral to waste removal. When the organ is injured, damaged cells initiate an immune response, while healthy cells nearby begin to replicate.

This type of cell replication involves somatic cells and results in the diploid number of chromosomes called mitosis. Skin cells are somatic- they contain all 24 pairs of human chromosomes. During replication, the chromosomes are unwound, and copied- then, the newly copied chromosomes separate into two identical daughter cells with the same chromosome number.

What is the source of oxygen as a reactant in cellular respiration?

Answers

Answer:

The Reactants

What goes into the cell? Oxygen and glucose are both reactants of cellular respiration. Oxygen enters the body when an organism breathes. Glucose enters the body when an organism eats.

Explanation:

Hope this helped, Thanks :)

Cellular respiration has been the chemical process that uses glucose to produce energy. Oxygen is the reactant of the process that comes from the air (breathing) produced by photosynthesis.

What is cellular respiration?

Cellular respiration has been defined as the process vital for living organisms that use oxygen and sugar molecules to produce energy to drive the activities and functions of the body. The reactant of the process includes glucose and oxygen gas.

Oxygen and sugar are known to be the product of the photosynthetic reaction that uses carbon dioxide and water. The oxygen gas is present in the atmosphere and enters the body through breathing.

Therefore, oxygen acts as a reactant in cellular respiration that comes from the breathing process.

2. Where are red blood cells produced?

3. What type of cells help blood to clot?

4. What makes the human circulatory system efficiently carry oxygen to the tissues?

5. Describe the role of blood plasma.

6. Explain the role of lymph in our body

Answers

1. Erythrocytes is red blood cells, and anemia means a lack of red blood cells in the blood. So erythrocyte count in a patient diagnosed with anemia such as pernicious anemia is going to be significantly lower than normal.

2. RBC’s (red blood cells) are produced in the bone marrow
3. Platelets help with clotting as well as clotting proteins produced in the liver
4. The human circulatory system is designed specifically to transport oxygen as well as nutrients to all parts of the body through blood vessels. Humans in the womb have blood vessels and a beating heart developed by the 1-2 months in the womb, and the heart immediately begins work. The human circulatory system is efficient because we were created with a system to be as efficient as possible. The circulatory system is basically a highway made of tunnels that allows RBC’s and WBC’s to pass through to every part of the body including major organs. Unfortunately unhealthy eating habits and poor exercise cause this circulatory system to become less and less effective till the point of heart attack, stroke, or major cardiovascular disease.
5. Blood plasma is very important in the transfer of nutrients as well as hormones to the major organs of the body.
6. Lymph is a clear watery substance that carries proteins and other substances throughout the body in order to maintain fluid balance. Lymph is part of the lymphatic system which is a tiny constituent of the immune system.
