Give a brief explanation of why food webs are preferred over food chains for representing the flow of energy in an ecosystem.
olga nikolaevna [1]
<h3><u>The Food webs are preferred over food chains for representing the flow of energy in an ecosystem for the following reasons: </u></h3>
  • The food webs are higher in complexity when compared to food chains and also, in food web, more than one primary producers is present which increases the 'flow of energy' in the ecosystem.
  • Food web represents the real life better than the food chains do.
  • Food web shows many different paths through which the organisms can be connected.

If a hemoglobin molecule comes into close contact with a respiring cell, the presence of CO2 in the environment will cause hemog
lapo4ka [179]

Answer:

No, when the concentration of carbon dioxide is high, such as in peripheral tissues, CO2 binds to hemoglobin and the affinity for O2 decreases, causing it to release.

Explanation:

The O2 molecule is reversibly combined with the heme portion of the hemoglobin. When the partial pressure of O2 is high, as in the case of pulmonary capillaries, for example, the binding of O2 to hemoglobin and the release of carbon dioxide are favored, this is known as the Haldane effect. If, on the contrary, when the concentration of carbon dioxide is high, such as in peripheral tissues, CO2 is bound to hemoglobin and the affinity for O2 decreases, causing it to release, this is known as the effect Bohr.

The image shows a magnified view of a leaf's surface with the stomata visible. What’s the significance of these structures in th
Deffense [45]

The correct answer is option (d) They allow the exchange of gases between cells in the leaf and the external environment.

Stomata are the tiny openings present in the epidermis (outer layer of cells) of the leaf. They have a pore which is guarded by the guard cells which controls the opening and closing of the stomata. Air enters and exits through the stomata.

The main funtion of stomata is to facilitate the gaseous exchange. The gas exchange that occurs when the stomata are open helps in the process of photosynthesis. During photosynthesis, carbon dioxide is taken in from the atmosphere and oxygen is released as a by-product of photosynthesis. The glucose produced is converted into the starch and stored in the leaves.

Also, water vapour diffuses through the stomata into the atmosphere by a process called the transpiration.

Thus, stomata are the structures that are mainly involved in the gaseous exchange between the cells of the leaf and the atmosphere.

bulgar [2K]

Answer:

Inbreeding leaves animals susceptible to genetic disease, and populations to reduced fitness. This family of three would not be able to sustain a population given their a) group dynamics and b) genetic variation

Explanation:

In small populations, the variation in genetic material is likely to be low. The consequence of this is that there is increased homozygosity. That means less members of the population carry two different alleles of a gene for any given trait. This increases the chance of the appearance of recessive traits, which could be disease causing or otherwise reduce fitness.

With only three related individuals left, the chances of generating a new and thriving population with the limited genetic material is almost non existent, especially considering the animals are a male, female and their pup
