Answer:
i think the answer is B
Explanation:
Specialized means they preform a specific task.
Answer:
The correct answer will be option E.
Explanation:
The features given in the question are the characteristics features of the group of bacteria belonging to Cyanobacteria.
These Cyanobacteria are the prokaryotes which are capable of synthesizing the food through a process called photosynthesis. These bacteria use sunlight as their energy, use water and air to synthesize food. They under anaerobic condition synthesize the nitrogen in special structures called heterocyst, a characteristic feature of cyanobacteria.
Thus, the features given in the question are:
1. contain photosystems to carry out photosynthesis.
2. producing oxygen
4. contain phycobilins
6. Hetrocysts: nitrogen-fixing structures.
7. The ancestor of plant chloroplasts.
Thus, option E is the correct answer.
Plant cells have cell wall but animal cells don't have any cell wall.
The process which produces an exact copy of the parent organism is asexual.
A rainforest ecosystem would have a more high species riches. There are vast resources such as trees and plants that contribute to animal life. More animals live in these ecosystems because of the environment itself.
A dessert ecosystem would have a low species riches. There is little plant life and low resources for survival. Only animals that have adapted to this environment have a high species rate.
