Answer:

Vacuole

Explanation:

Apart from cell wall, vacuole plays an important role in maintaining rigidity of plant cells. It is a membrane bound fluid filled sac. Vacuole can expand in size greatly.

When the outside environment is hypotonic, plant cell takes in excess of water. This water is taken up by vacuole and it can stretch to fill out around 90% of cell without losing its integrity. The cell is said to be turgid and all other organelles press against the cell wall without facing any damage. The development of this hydrostatic pressure helps to maintain the rigidity of the cell along with cell wall.

Simone is creating a model to track the movement of carbon atoms in an ecosystem. Which statement best explains the role of plan
Mademuasel [1]

Although I cannot see the model for Simone's experiment, I can offer the insight that the most likely role of plants in the model is that they consume the carbon atoms and produce oxygen.

<h3>How do plants affect the carbon in the atmosphere?</h3>
  • Plants are known to have a<u> great effect</u> on the carbon levels of the atmosphere.
  • The correlation is that the more plants are present, the less carbon is free in the air.
  • The reason for this is that plants use carbon dioxide as a substrate to manage the process of photosynthesis.
  • As a by-product, after consuming carbon dioxide and completing photosynthesis, plants release oxygen into the atmosphere.

Therefore, we can confirm that the most likely role of plants in the model created by Simone, is that they will consume carbon atoms in the form of carbon dioxide in order to sustain photosynthesis, which releases oxygen.

lianna [129]

If you turned a frog egg upside down, you would expect it to reorient relative to gravity because the dense yolk granules concentrated in the vegetal hemisphere of the egg respond to gravity.

The frog egg is very large as compared to the normal egg cell. It is unevenly distributed with a top dark colored pole called animal pole and a light yolky pole called a vegetal pole.

The vegetal pole is concentrated with the yolk that is present for providing the nourishment to the growing embryo. The animal pole is the one from where the sperm enters and the development of embryo take place.

As the vegetal pole is denser as compared to animal pole so it will respond to the gravity and reorient along the direction of gravity.

An average number of eggs a bird lays is based on natural selection. If a bird lays too many eggs, there a high chance that she
mr_godi [17]

The correct answer is stabilizing selection.

Stabilizing selection is a kind of natural selection in which the mean of the population steadies on a specific non-extreme trait value. This is considered to be the most general process of action for natural selection as the majority of the traits do not seem to vary radically with time.

Stabilizing selection is the reverse of disruptive selection. In spite of preferring individuals with extreme phenotypes, it favors the transitional variants. Stabilizing selection seems to eradicate the more extreme phenotypes, resulting in the reproductive success of the average or norm phenotypes.

This signifies that the most general phenotype in the population is chosen and continues to govern in the coming generations. As the majority of the traits vary slightly with time, stabilizing selection is considered to be the most usual kind of selection in the majority of the populations.
