An environmental scientist might study the effect of soil pollution on plant growth.
Elena L [17]
  • <u><em>True.</em></u>

As...Environmental scientist studies the interaction of the living components of the ecosystem with the non living components.

The contamination in the soil will affect the growth of plants, this will also be studied by the environmental scientist.

The Growth of the plant depend on the quality of soil in which it is grown so it will also be a concern for the environmental scientist.

A group of cells is assayed for DNA content immediately following mitosis and is found to have an average of 4 picograms of DNA
damaskus [11]

Answer:

b: 8;8

Explanation:

Mitotic or meiotic cell division constitute the m phase of the cell cycle. At the end of the m phase, the new cells enter the interphase stage of the cell cycle. The interphase is further sub-divided into;

  • <em>the G_0 phase,</em>
  • <em>the G_1 phase,</em>
  • <em>the S phase; and</em>
  • <em>the G_2 phase</em>.

The G_0 phase is essentially a resting phase. Cells that do not need to divide except when necessary move into this phase after exiting the m phase.

Actively dividing cells enter the G_1 phase after exiting the m phase. Cell development and growth takes place. From there, the cells enter the S phase where DNA replication/synthesis takes place. The cells then enter the G_2 phase where proteins are synthesized in preparation for division or m phase.

At the S phase, the amount of DNA a cell carries is doubled but the chromosome number remains the same. For example, if a cell enters the S phase with 2 g of DNA containing 10 chromosomes, at the end of S phase, the amount of DNA would have come 4 g while the number of chromosomes will remain 10.

Hence, if the average amount of DNA in the assayed cells immediately after mitosis is 4 picograms, the amount would be 8 picograms at the end of S phase and will still remains 8 picograms at the end of G_2 phase.

The correct option is b.

What is true about translation? Choose ALL that apply.
Licemer1 [7]

<u>In the process of translation, the statement stands correct and applies are as follows:</u>

  • The ribosome has two sub-units that work together.
  • Amino acids are joined by peptide bonds.
  • Each tRNA brings in exactly one amino acid that corresponds to the anti-codon.
  • The order of the amino acids is determined by the mRNA which is transcribed from DNA.

Answer: Options A, B, C, and E

<u>Explanation:</u>

In the process of translation, ribosomes are the structural unit where the translation is being performed and it has the two sub-units which enact together the translational process.

Any two amino acids are bonded together by peptide bond and tRNA brings one amino acid at a time which corresponds to the anti codon. The order of amino acids is determined by mRNA transcribed from the DNA, and not from the ribosome. Thereby, all given options are correct except the option D.
