Answer:

C. The pond experienced an algae bloom.

Explanation:

From the graph we see that the fish population continue to decrease with time. As time passed on, the fish population keeps suffering a decline. In retrospect, the population of the algae continued to increase.

  • We can ascribe this to the pond experiencing an algae bloom.
  • It could be due to condition called eutrophication.
  • When nutrients become very much in water and more algae is produced.
  • This leads to dissolve oxygen amount reducing in the water body.
  • Therefore, fishes will die off.

When Mendel’s first generation pea plants were allowed to self-pollinate, the ratio of tall (dominant) to short (recessive) plan
Katyanochek1 [597]
The ratio of tall to short in the second or the F2 generation was 3:1. Because the resulting genotype of the F1 generation would be Pp. If you test cross that and put in into a Punnet square, you would have three blocks that have the dominant trait and one block without. Remember that the dominant trait is always expressed. So three of them would be tall and one would be short. 

You answer is then D.

How are monotremes different from other groups of mammals?
fredd [130]

Answer:

The correct answer will be -they lay eggs

Explanation:

Monotremes are the animals which belong to the group of mammals. There are only five species of monotremes known today which are found in New Guinea and Australia.

The monotremes differ from other mammals which is that they lay eggs instead of giving birth to the young ones. This shows that these mammals are closely related to the reptiles and amphibians and are thus the primitive mammals.

Thus, they lay eggs is the correct answer.

What does maintaining structure mean for organisms and reproduction​
OlgaM077 [116]
All organisms consist of structural units called cells; some contain a single cell (unicellular) and others contain many units (multicellular). Multicellular organisms are able to specialize cells to perform specific functions. Organisms have both internal and external macroscopic structures that allow for growth, survival, behavior, and reproduction.. All living things are made up of cells. In organisms, cells work together to form tissues and organs that are specialized for particular body functions.
