Which of the following is not a step in the process of natural selection
Paraphin [41]

Answer:

A step that is not part of natural selection is people select which individuals breed and which ones do not.

Explanation:

Natural selection is a process in which favorable or unfavorable environmental conditions determine the evolution of species, producing differences in their genotype over a long period of time.

As its name indicates, it is a natural selection, in which no intervention by people is contemplated, so that <u>people cannot determine which individuals breed</u>.

Natural selection implies that the characteristics on which the environment influences are inheritable, that there is genetic variability in the population and that the variability of these characteristics implies the ease of reproduction and survival capacity.

<em>The other options do form part of natural selection, since they are based on the three premises of this process: </em>

  • <em>Inheritable characteristics. </em>
  • <em>Genetic variability. </em>
  • <em>The variability of characteristics influences reproduction and survival.</em>

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.

According to some botanists, invasive plants are the second most serious threat, after habitat loss, to native species of plants
Nataliya [291]

Answer: option A - threat, after habitat loss, to native species of plants and animals and to the maintenance of biologically diverse ecosystems

Explanation:

Invasive species refers to organisms that appears at a particular habitat that has just undergone an environmental unfavorable condition.

These INVASIVE SPECIES poses THREAT to the native organisms, because they usually possess:

better resistance to disease,

higher reproductive rate, etc.

So, even when native organisms migrate or dies, Invasive species REMAINS. As a result, they threaten the maintenance of a biologically diverse ecosystem
