Alex Ar [27]
This is a typical example of R selection life strategy. These species, including the Atlantic cod, produce a large number of offspring with a low chance of surviving to adulthood. This strategy is particularly successful in environments that are unstable. The main advantage of this strategy in changing environments is that the ''cost'' of making offspring is very low, so you the species can produce large numbers offspring, ensuring that at least some of them will survive into adulthood and continue the species.
Natural selection, in this case, favors the individuals that are able to adapt the fastest to the changing conditions.

You examine an epithelial cell (skin cell) and notice the chromosomes are visible however it appears there are two nuclei in the
krek1111 [17]

Answer:

The best explanation if we observe an epithelial cell with chromosomes are visible and two cell nuclei is that the cell has just gone through telophase but not cytokinesis (option b).

Explanation:

A somatic cell, when found in mitosis, exhibits the chromosomes distributed in both poles and the outline of two nuclei in the telophase phase, just before cytokinesis.

In mitotic telophase:

  • Chromatids, which are chromosomes, are found in the cell poles.
  • It initiates the formation of the nucleus membrane.
  • The chromosomes begin to turn into chromatin.
  • Disappearance of the mitotic spindle, duplication of organelles and cytoplasmic invagination.

The division and differentiation of the nuclei in telophase is called karyokinesis. Later, cytokinesis occurs, where the daughter cells are separated.

The other options are not correct because:

<em>     a and d. In the other phases described, </em><em><u>S and G1,</u></em><em> no chromosome distribution is observed at the poles.</em>

<em>     c. A somatic cell does not experience </em><em><u>meiosis</u></em><em>.</em>

<u>The four types of interactions in communities are:</u>

  • Mutualism
  • Parasitism
  • Commensalism
  • Competition

<u>Definition of each interaction:</u>

<em>Mutualism: </em>

The type of interaction in which both the species involved are benefited, it is called mutualism.

<em>Parasitism:</em>

The type of interaction in which one species is benefited, whereas the other is harmed, it is called parasitism.

<em>Commensalism:</em>

The type of interaction in which one species gets benefited without harming or providing benefits to others is called commensalism.

<em>Competition:</em>

The type of interaction in which both species lose is called competition. It is opposite of mutualism.

<u>Symbiotic relationship:</u>

It refers to the type of interaction in which lastly one species gets benefited. The type of interactions such as <em>mutualism, commensalism, and Parasitism </em>are considered as symbiotic relationship.
