In this image, there is a representation of the antigenic shift or change takes place to evolve to a new strain of influenza virus from the original virus that has a different antigen on the surface of the virus than the new strain. In this image it is shown that the surface H antigens went through a shift to form a new strain while N antigen remain the same.
This is important to adapt and evolve according the internal environment of the host show this type of mutation requires if moving from one host to another (human to pigs).
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 insulin and why do people with Type 1 diabetes need it to survive?
Answers
Answer:
Insulin is needed to move blood sugar (glucose) into cells. Inside the cells, glucose is stored and later used for energy. With type 1 diabetes, beta cells produce little or no insulin.
Stand and let your hands hang next to your sides for a few minutes. Then, look at the backs of your hands. Do you see any bumps on the surface on top of your veins? What might those be, and what are their function?
Answers
When you stand and let your hands hang next to your sides for a few minutes, the bumps you see on your veins are the valves that help move blood to the larger veins.
What we know about vein valves.There are valves located throughout the veins in our bodies. Most of these are located in points where smaller venules fuse with the larger veins.
Their function is to prevent blood from flowing back into the smaller veins, thus helping with the normal blood flow of the body.
Given that the veins in our bodies are littered with small valves to help the blood return to the heart correctly, we can confirm that these are the small bumps that we can see when letting our hands down for a few mins, as they fill with the blood they try not to let flow back into the smaller veins.

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.

The most basic definition of cellular respiration is that it is cells breaking down food to make energy. True or false?
Answers
Answer:
True
Explanation:
In cells, energy is obtained from food through the process of cellular respiration. In mitochondria, this occurs through aerobic respiration- here, cells breakdown sugars like glucose into carbon dioxide and water and energy in the form of ATP or adenosine triphosphate.
In cellular aerobic respiration:
C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
