Answer: 21%
Explanation:
The atmosphere is the gaseous portion of the planet Earth. It therefore consists of several gases and air particles.
In the atmosphere,
-Nitrogen is the most abundant gas with 78%
- Oxygen takes 21%,
- Carbon dioxide takes 0.03%,
- the remainder is unreactive gases and particles.
Animals will migrate to other regions in search of food
The new species will evolve to survive in the deforested land
It's highly unlikely the animals will immediately adapt and the number of trees is decreasing because they're being cut down. Unless the question explicitly states that trees are being planted to replace those being lost.
Answer:
It's a form of asexual reproduction!
Development of the offspring happens without fertilization in this type of reproduction.
The two main ways in which parthenogenesis happens is by apomixis or automixis. Through apomixis , the egg cells are produced by mitosis. Through In automixis, egg cells are produced by meiosis.
Mitosis = a part of cell cycle: replicated chromosomes are separated into 2 nuclei
Meiosis = type of cell division that reduces the chromosome number by half. So now there is four haploid cells that are genetically distinct from their parent cell.
Example:
An example of an animal that can use this reproduction is a bonnethead shark! Once a shark had a baby in a tank that only had three females!
(read about that on wikipedia)
I believe alleles for the same trait are separated from each other during the process of meiosis.
Answer:
I think Indirect contact with animal feces
hope it helped :)
