Ras is a g-protein that is activated when a growth factor attaches to egfr. its activation results in the in the exchange of gtp
Artist 52 [7]
RAS is a very important protein that belongs to a class of protein referred to as GTPases and plays a crucial role in switching on pathways that control cell growth, proliferation, apoptosis and differentiation and migration. For RAS to become inactive it must hydrolyze GTP to GDP which slows down the process of cell proliferation. Mutation in one copies of RAS will result to cancer because the mutated copy will permanently attach to GTP and remain in activated form which will lead to uncontrollable cell division and hence development of cancer.

Which question is testable?
Nuetrik [128]

The correct answer is: A. How does changing the amount of water affect the growth of corn?

While options B, C & D are not impossible to test, option A is the only question that can be tested using quantitative methods, such as statistical analysis. The question in option A states: "How does changing the amount of water affect the growth of corn?". This question is easily testable using scientific investigation, because controlled or measured amounts of water can be added to corn, and the consequent growth rate of corn can be easily measured and recorded. However, the questions in options B, C & D cannot be precisely measured using quantitative tools, since they aim to measure qualitative (subjective) factors, such as: ethics, happiness and disappointment.

What aspect of chromosome behavior most clearly accounts for Mendel's law of segregation?
svetlana [45]

The given question is incomplete as the group of choices lack the correct answer, however, the correct group of choices are as follows:

A. Movement of sister chromatids to opposite poles at anaphase II of meiosis.

B. Movement of homologous chromosomes to opposite poles at anaphase I of meiosis.

C. Crossing over between homologous chromosomes during prophase I of meiosis.

D.  Replication of chromosomes prior to meiosis.

E. Independent alignment of different homologous pairs on the metaphase I spindle.

Answer:

The correct answer is :  Movement of homologous chromosomes to opposite poles at anaphase I of meiosis.

Explanation:

The Mendel's law of segregation says that during formation of gametes the copies of genes segregate from each other so each gamete has equal and only one allele of the gene.

This behavior of homologous chromosome can be seen in anaphase I in meiosis, responsible for the segregation of copies of allele into different copies.

Thus, the correct answer is :  Movement of homologous chromosomes to opposite poles at anaphase I of meiosis.
