Theories may change over time. Unversal laws are supposed to not change.

Most theories and laws cannot not be definetly proved and they are constantly tested.

Consensus is not necessary. Many theories were discarded by the majority of scientific community before been accepted.  

Both theories and laws must be based on scientific method and observations are a key part of it. Then, in my opinion, the true statement is that both are supported by observartios.

Which structure receives sperm from the efferent ductules and sends it on to the vas deferens
yawa3891 [41]

Epididymis receives sperm from the efferent ductules and sends it on to the Vas deferens.

Epididymis is a structure that forms a connection between the efferent ductules and vas deferens.

Epididymis is a structure that helps in the maturation of sperm and make it functionally mature to carry out fertilization in the human female body. It stores the sperm cells. It matures the immature cells from the testis.

Epididymis is divided into three parts namely:

  • Caput Epididymis: Part where sperm enters from testis directly
  • Corpus Epididymis: Part where sperm gain motility
  • Cauda Epididymis: Part where sperms are stored

Epididymis is an important region of the ductules present in the transportation of sperm out of the testis and towards the urethra of the male body.

Imagine you do a version of the Beadle-Tatum experiment in which you attempt to test the one-gene, one-enzyme hypothesis, but us
AysviL [449]

Answer:

They would be the enzymes that assimilate the presence of Q to generate a metabolism that encourages growth.

And also those that are X-forming, which is what is always present in cells.

Explanation:

Therefore, all the enzymes that assimilate the amino acid Q continue to function.

In simple words, in this situation, amino acid Q went from being a non-essential amino acid (because it was manufactured in-house) to being an essential amino acid (which, if or if, must be administered by the medium due to lack of own production in order to generate growth) .

The virus introduced to the island in 1982 that reduced the wolf population is an example of ________.
KengaRu [80]

The virus introduced to the island in 1982 that reduced the wolf population is an example of a density dependent factor.

In ecology, a density-dependent factor, also known as a regulatory factor, is any force that modifies the size of a population of living creatures in response to population density.

Because of their propensity to maintain population densities, density-dependent factors are also known as regulating factors.

Population size and a density-dependent factor's level of control are correlated, therefore an increase in population will increase the influence of the limitation. Density-dependent factors involve biotic factors such as availability of food , predation, competition,  parasitism and disease.
