Imagine that you are Gregor Mendel and you want to assure yourself that the F1 generation plants you generated from crossing true-breeding plantsactuallyare heterozygotes. You perform a testcross by mating all of your F1 smooth pea plants with plants that are homozygous recessive (wrinkled pea plants).

Answers

Answer 1
Answer: You should find another homozygous recessive if it it a homozygous dominate then you will not receive any recessive plants

The cambium produces xylem toward the center of a tree and phloem toward the outside. do you think it would make any difference if the positions of the xylem and phloem were reversed? why?

Answers

The wood is xylem, and the bark is phloem. So, if you reverse the two, the tree is unlikely to be able to support its own weight.

What is are vascular tissues?

Vasculartissue is an intricate conductingtissue found in vascular plants that is made up of multiple cell types.

The xylem and phloem are the primary components of vascular tissue. From within, those same two tissues transport fluid as well as nutrients.

In plants, cambium is a layer of actively dividing cells that exists between xylem (wood) and phloem tissues and is responsible for the secondary growth of stems and roots.

A cambium is a tissue layer in plants that provides partiallyundifferentiated cells for plant growth.

It is found between the xylem and the phloem. A cambium is also a cellular plant tissue that grows phloem, xylem, or cork by division, resulting in secondarythickening.

The wood is called xylem, as well as the bark is called phloem. If the two are reversed, the tree is very unlikely to be able to endorse its own weight.

Thus, this can be the consequence of reversing the xylem and phloem.

Which characteristics of DNA polymerase I raised doubts that its in vivo function is the synthesis of DNA leading to complete replication?

Answers

The question is incomplete. The complete question is as follows:

Which characteristics of DNA polymerase I raised doubts that its in vivo function is the synthesis of DNA leading to complete replication?

its composition of a single polypeptide chain.

deficiency of enzyme in some organisms that are still capable of DNA synthesis.

requirement of Mg2+ presence in order for the enzyme to work.

low stability under normal physiological conditions.

Answer:

Deficiency of enzyme in some organisms that are still capable of DNA synthesis

Explanation:

The DNA polymerase I may be defined as the important enzyme that play an important role in the DNA replication of prokaryotes. DNA pol I is the replicating enzyme, DNA repair enzyme and can also acts as the exonuclease.

DNA pol I has been studied invitro and Arthur Korenberg explain the discovery of the DNA pol I. This DNA pol I plays an important role in DNA repair rather than the replication process. This explained invivo by the fact that some in some organisms the deficiency of this enzyme do not halt the process of replication. If the DNA pol I acts as the main replaicating enzyme, the DNA synthesis must be stopped in the organisms that lack DNA synthesis.

Thus, the correct answer is option (2).

SNP is an acronym for:A. simple Northern probe
B. sample in situ probe
C. simple nucleotide probe
D. single nucleotide polymorphism polypeptide
E. sequence normal

Answers

Answer:

single nucleotide polymorphism

Explanation:

A SNP (above) is a mutation in DNA at exactly one nucleotide (A, T, C, or G) that is present in at least 1% of the population.

For instance, let's say a certain protein relies on the sequence -TTG- at a certain position in a gene. If the sequence -ATG- is seen in that exact position in the gene (the A residue replacing the first T residue) in at least one percent of the population, this would be a SNP. If this replacement were in less than one percent of the population, it would just be a mutation.

Suppose that you began a one-year study of tuberculosis (TB) in St. Petersburg on January 1st, 2018. You enrolled 200 residents in your study and checked on their TB status on a monthly basis. At the start of your study on January 1st, you screened all 200 residents. Upon screening, you found that 10 of the healthy residents were immigrants who were vaccinated for TB and so were not at risk. Another 10 residents already had existing cases of TB on January 1st. On February 1st, two residents developed TB. On April 1st, three more residents developed TB. On July 1st, three of the residents who had existing TB on January 1st died from their disease. The study ended on December 31, 2018. Assume that once a person gets TB, they have it for the duration of the study, and assume that all remaining residents stayed healthy and were not lost to follow-up.What was the prevalence of TB in the screened community on January 1st?
