Answer
Use Mitosis to divide and create daughter cells.
Explanations
Single-celled organisms use mitosis to reproduce. Both growth and reproduction in unicellular organisms are mutually inclusive. When the cell’s volume grows, the ratio of surface area to volume decreases creating challenges in acquisition of nutrients because there will be too much cytoplasm for a given amount of nuclear material , thus the cell divides by mitosis to reproduce daughter cells and the process begins again.
Answer:
b) convolutions
Explanation:
The part that makes the outer rim of the cerebrum is the cerebral cortex. It is composed of gray matter. The billions of neurons of the cerebral cortex are organized in distinct layers. During embryonic development, enlargement of the brain is accompanied by even more enlargement in the gray matter of the cerebral cortex. However, it fits into the skull due to its folds which are also called convolutions or gyri. The cortical region rolls and folds on itself.
Answer:
Anthropoids lived for approximately 0.86% of the total time.
Explanation:
- Anthropoids are the higher developed organisms that includes apes and ape mans.
- The age of earth is 3500 million and anthropoids lived for about 30 million years.
- By the simple calculations we can find out the data in percent which gives us the result nearest to 0.86%.
- That means 0.86% of 3.5 billion year is equivalent to 30 million years (time that was lived by anthropoids).
