We are given with 2 genes homozygous tall plants (TT) with homozygous short plants (tt). The ensuing offspring are tall, which implies the dominant attribute is tallness. this can be true since the chance of various height like all are short or some are tall and short could also be doable. answer is a
allele for tall plant height was dominant
Explanation:
Gregor Johann Mendel, called the "father of recent biology," was born in European country in 1822. His experiments showed that the inheritance of bound traits in pea plants follows explicit patterns, later turning into the inspiration of recent biology and resulting in the study of heredity.

Answer:
a) withheld information from test subjects about their condition
Explanation:
The Tuskegee syphilis study which was carried between 1932-1972 in the Macon County, Alabama on the African-Americans infected from syphilis.
The U.S. Public Health Service started the study promising the infected persons that they will receive the benefits from the studies like a healthy meal, proper antibiotic medication and other benefits.
But the U.S Public Health Service failed to provide the services mainly the medication in which antibiotic penicillin which could treat the disease was not provided to the patient. As a result of this, syphilis continued in their generations also and people and about 100 subjects died.
They were told that they had bad blood which cannot be treated and thus in 1972, this raised a question over this issue related to ethics as to why the penicillin was not provided as well why the person was kept away from the reality.
Thus, Option-A is the correct answer.
Answer:
Artery : carries blood away from the heart, largest blood vessel in diameter
Vein : carries blood to the heart, has a thin endothelial layer.
capillary : exchanges nutrients with tissues, single walled.
Explanation:
Arteries are blood vessels that transport blood away from the heart to the body. They are the largest blood vessels in the body and have thick elastic walls.
Capillaries are blood vessels that carry blood away from body and exchange waste, nutrients, and oxygen with cells or tissues. Capillaries are smallest blood vessels and their walls contain only a single layer of tissues.
Veins are blood vessels that transport the blood from the body to the heart. Veins have less connective and smooth muscle tissue that make veins' walls thinner that walls of arteries.
