It might pollute the air and water so most animals have to go, and the animals who are completely fine, they won't have any food so they'll end up dying. The ones who left, there's a 95% chance they won't survive. They had to leave because mostly everything (Water, air, food, and plants) was polluted.

The images represent sexual and asexual reproduction. These methods of reproduction vary in terms of the genetic
sattari [20]

Asexual reproduction

Sexual reproduction

Explanation:

In asexual reproduction the offspring are genetically identical to the parents.  Asexual reproduction include binary fission, fragmentation and vegetative propagation.

It involves direct inheritance of the genetic copy of the parent without any alteration. The parent gives rise to the offspring without any intermediary process.

In binary fission, the parent simply divides into two to form a new ones.

For sexual reproduction, there is fusion of gametes which carries genetic materials contributed by both parents. The offspring is an offshoot of the genetic combination of the traits of two parents.

Therefore, genetically, offspring produced by sexual reproduction have a distinct copy of the genotypes they posses. They are different from those of the parents.

In which part of the cell do ribosomes complete protein synthesis?​
olga nikolaevna [1]

Answer: nucleus

Explanation:  In eukaryotes, ribosomes get their orders for protein synthesis from the nucleus, where portions of DNA (genes) are transcribed to make messenger RNAs (mRNAs). An mRNA travels to the ribosome, which uses the information it contains to build a protein with a specific amino acid sequence.
