Mutation are two types somatic and germ cell mutation...as there is mutation in germ cell it will alter the normal behavior and produce variation !
random fertilization also causes variation as different setup of genes meets with another different...so chances of variation increases !
and third crossing over is in meiosis when chiasmata forms....so in this two homologous chromosome attach to each other and on separation ... some part exchange so leads to variation !
Abiotic factors are things in an ecosystem that aren't alive.
Here are a few examples of abiotic factors in a rain forest:
1. Sunlight
2. Water
3. Soil
4. Rocks

During exercise there is an increase in physical activity and muscle cells respire more than they do when the body is at rest. The heart rate increases during exercise. The rate and depth of breathing increases - this makes sure that more oxygen is absorbed into the blood, and more carbon dioxide is removed from it.
Bacterial translation is initiated in three steps. In the final step, the large ribosomal subunit binds to the mRNA.
The ribosome's translation of an mRNA molecule occurs in three stages: initiation, elongation, and termination. The small ribosomal subunit binds to the beginning of the mRNA sequence during initiation. Most eukaryotic mRNAs initiate translation by binding Met-tRNAiMet to a 40S subunit, followed by ribosomal attachment at the 5′ end of an mRNA, scanning to the initiation codon, and joining with a 60S subunit to form an 80S ribosome. The stages of translation should be completed in the following order: Initiation, Elongation, and Termination.

Answer:
1. Food (or other animals that are their prey),
and the other blank would be:
2. Causing them to choke, digestive issues, or even death.
Explanation:
Plastic waste should not be littered around because of the dangers it brings to animals. For example, balloons and plastic bags pose a threat to sea turtles because if they float into the ocean, the turtles may assume they're jellyfish from their appearance and attempt to eat them.
