A science class investigated the relationship between the amount of time
zaharov [31]

Answer:

A. Based on our results, students who do 1 hour of chores per night

have grades that are on average 0.2 points higher than students

who do no chores.

Explanation:

In a scientific experiment that employs the scientific method, series of steps should be followed. The steps involved in the scientific method include; making an observation/asking a question, formulating a hypothesis, testing the hypothesis, analyzing the result, drawing a conclusion etc.

From this step, we would notice that DRAWING CONCLUSION immediately follows the analysis of result, which means the conclusion is based on the result of the experiment. A conclusion in a scientific experiment should be factual and based on the measured result. It should either reject or accept the hypothesis.

The best representation of a conclusion is A. Based on our results, students who do 1 hour of chores per night have grades that are on average 0.2 points higher than students who do no chores. This statement has a conclusive content unlike other options that still seemed unlikely.

Inessa05 [86]

Answer:

intrinsic

Explanation:

Proteins are dynamic molecules that are capable of INTRINSIC motion that can have important functional relevance. The existence of this type of motion has suggested that enzymes are capable - even in the absence of substrate - of many of the same movements that can be detected during their catalytic cycle

One oak tree cell with 14 chromosomes undergoes meiosis. How many cells will result from this process, and what is the chromosom
Alchen [17]

The correct answer is - 4 and 7 chromosomes in each cell.

Explanation:

Meiosis is the cell division in which one parent cell produces four daughter cells with a half number of the chromosome than parent cells.

According to the question oak cell performed meiosis which is reduction division so the number of cell will be four and 7 chromosome will be present in each daughter oak cell.

Thus, the correct answer is - 4 and 7 number of chromosome in each.

if a retrovirus could infect one of any of these kinds of cells, which would amplify it the most within the first 2 hours?
ryzh [129]

Cancer cells are the best target to amplify the most within first 2 hours. Highly oncogenic retroviruses are recombinants of viral and host genes.

Retroviruses are viruses with RNA rather than DNA in their genomes that infect cancer cells. Reverse transcriptase is an enzyme that is used to integrate into the DNA of the host cells. It is enhanced to a greater extent the more cell replication takes place. More retroviruses are then produced by the cell, infecting further cells. Many diseases, including AIDS and various types of cancer, are linked to retroviruses.

Low-incidence cancer-causing retroviruses lack inserted host information. Instead, it seems that they alter the expression of potentially carcinogenic host genes, which in turn results in cancer. Retroviruses incorporate proviral DNA into the chromosomal DNA of their host during the course of their regular life cycle. Integrations take place across numerous locations. Although most integrations are benign, some can cause cancer. Many of these seem to encode tyrosine phosphorylating protein kinases.
