Answer:
Explanation:
The percentage of adenine will equal the percentage of thymine, and the percentage of cytosine will equal the percentage of guanine. Together, these percentages will add to 100%. We know that the sample is 35% adenine, which tells us that it is also 35% thymine.
Answer:
The percentage of thymine would also be 35%.

Answer:
Feedback loop
Explanation:
A feedback loop is a process in which the body tends to return to homeostasis if it deviates from normal conditions.
A feedback loop consists o three components a receptor, a control center and an effector.
There are two types of feedback loops namely, positive feedback loop and negative feedback loop.
In a negative feedback loop, the effect of the stimulus is to shut off the original stimulus or reduce its intensity, while in positive feedback loop, intensifies a change in the body's physiological condition.

At first the Solar radiation hits the earth~ The sun's energy is then absorbed~ Head radiates into space from Earth~ This traps the heat and makes Earths Temperature hotter~ are the correct arrangement of green house effects. Hence, option A is correct.
What is green house effects?Green house effects are the rays in which heat are taken hold close to earth surface that is near to the earth. These effects have covered the earth like a blanket and keeps the planet toaster and warmer than it could be without them.
Greenhouse gases on Earth trap heat in the atmosphere, warming the whole globe. The primary gases that cause the greenhouse effect are fluorinated gases, as well as naturally occurring gases such carbon dioxide, methane, nitrous oxide, and water vapour which are synthetic.
Thus, option A is correct.

A.Complete Dominance
B. Codominance
C. Incomplete dominance
D. Polygenenic
Answer:
I will give you an explanation, and try to figure it out!!
Explanation:
Incomplete dominance can occur because neither of the two alleles is fully dominant over the other, or because the dominant allele does not fully dominate the recessive allele. This results in a phenotype that is different from both the dominant and recessive alleles, and appears to be a mixture of both.

to assist other lymphocytesto kill cells infected with a virus or cancerto help in the body's immune responseWhat are T-lymphocytes?
T-lymphocytes, also known as T cells, are a type of white blood cell that plays a key role in the immune system. They are produced in the bone marrow and mature in the thymus gland.
One of the main functions of T-lymphocytes is to assist other lymphocytes, such as B cells, in the immune response. They do this by releasing chemicals that help to activate and coordinate the immune response, and by directly attacking infected cells.
T-lymphocytes also have the ability to kill cells that are infected with a virus or cancerous cells. They do this through a process called cell-mediated immunity, in which they recognize and bind to specific proteins on the surface of infected cells. Once they have bound to the infected cells, they release chemicals that kill the cells, helping to prevent the spread of the infection or cancer.
T-lymphocytes are an important part of the body's immune system and play a vital role in helping to protect the body against infections and disease.

Sea turtles lay a large number of eggs in the sand. When the eggs hatch, the baby sea
turtles make their way back to the ocean water. How does laying a large number of
eggs help the sea turtles survive?
Answer:
It helps the sea turtles to survive because there are seagulls and other predators at the beach, so they will eat at least some of the baby turtles. But, when there are a large amount, the predators will be distracted with another baby turtle and hopefully at least some will make it to the ocean.
Answer:
C. It increases the chance that more sea turtles will survive and become adults.
