Answer:
<h2>Striated, smooth, and cardiac muscle cells contain vast numbers of cytoplasmic filaments that function during the contraction of these cells. ... The contraction of striated muscle cells shortens the muscle, which then moves the skeleton.</h2>
Answer:
Dogs shown in this picture belongs to the secondary consumer trophic level which consumes primary consumer herbivores. These primary consumer herbivores are dependent on grass for food which is a primary producer. If all dogs die, the population of primary consumer herbivores will increase. This increase will lead to decrease in grass at a drastic rate. Therefore, primary producers (grass) will be affected.
The answer to the biology question being presented above would be 'sexual reproduction'. Genetic variability is the most important result of sexual reproduction. In this variability, the genes are varied through sexual union and reproduction.
Answer:
C
Explanation
biodiversity adds variety to a habitat.
Answer:
In an aquatic ecosystem, the plants are present both on the subsurface and bottom bed rock of the aquatic body. These are the producers of the ecosystem because they provide food to the living organism in the lake. In day plants growing on the surface of the water takes up carbon dioxide from the atmosphere which is being absorbed in the water, to conduct the process of photosynthesis. These plants release oxygen, which supports the life of aquatic animals. In this way plants limit the abundance of carbon dioxide in water. But in night plants undergo a process of respiration, which releases carbon dioxide. The abundance of carbon dioxide increases in night along with the carbon dioxide being absorbed from the atmosphere. Therefore, concentration of carbon dioxide increases considerably in night as compared to day.
