bazaltina [42]

Answer:

a move from the fundamental niche to the realized niche for both species.

Explanation:

The niche of an organism is the functional role of the organism in the community or the ecosystem as a whole. This include the environment an organism lives and all the jobs it does in it.

Fundamental niche refers to all the possible functional roles of an organism in an ecosystem while realized niche refers to the specific roles the organism is limited to as a result of resource limitation, competition or other factors.

Resource partitioning involves the division of limited resources among organisms so as to avoid competition within the niche.

<em>Hence, resource partitioning causes a move from the fundamental niche of an organism to the realized  niche of that organism. </em>

SSSSS [86.1K]

Answer:

The correct answer is option d)"the percentage of pink flowers should increase over time".

Explanation:

In this study it is stated that two factors affect the flower coloration of <em>Claytonia virginica</em>: slugs preference of eating pink-flowering plants and bees preference of pollinating pink-flowering plants as well. If the researcher removes all slugs from the study population we can expect that the percentage of pink flowers should increase over time. The removal of the predator that prefers eating pink-flowering plants will favor the reproduction of this type of plants, which are also favored by bees pollination preference.

EXPLANATION OF PALISADE MESOPHYLL

  • Palisade cells are found in the mesophyll of a leaf and their main function is the absorption of light so that photosynthesis can take place.
  • The palisade mesophyll consists of chloroplasts with chlorophyll that absorb the light energy

1. The following statement is similar to those you might see on exams. Write a paragraph of 3-5 sentences describing 1) whether
yanalaym [24]

Answer:

The oxygen dissociation curve represents the percentage saturation of Hb with oxygen at different partial pressure of oxygen. The different partial pressures gives sigmoid shapes to the curve. When this curves shifts to right, it  indicates  low affinity or binding of oxygen by the Hb. it also indicates the unloading or releases of Oxygen by Hb molecules at condition of low pressure. e,g in the muscles during strenuous exercise.However, when the curve shifts to the left, this indicate high affinity for oxygen, great binding, at high partial pressure of oxygen.e,g in the lungs to take oxygen and releases CO2.

Therefore in this scenario, the statement -. <u>During strenuous exercise, the oxygen-hemoglobin dissociation curve shifts to the right.</u> is correct. because oxygen is needed by the muscles therefore ,oxygen should be less binded by Hb,  decrease affinity and easily unloaded to muscles.

<u>The statement </u>This rightward shift reflects an increase in the affinity of hemoglobin for oxygen and favors loading of O2 into hemoglobin in the lungs is wrong.

As explained above the rightwards shift indicated low affinity of Hb for oxygen(unloading)and  favours unloading at the muscles because during strenuous exercise the partial pressure of oxygen is very low(but that of CO2 high) in the muscles which favours low oxygen molecules  binding by Hb, and easy release to respiring cells.
