Answer:39 chromosomes
Explanation; meiosis is a form of nuclear division that produces gametes with half the number of chromosomes in the parent cell.it involves two successive divisions to produce four daughter cells.meiosis occurs only in reproductive cells.
In this case,the dog has 39 pairs of chromosomes,which is 78 chromosomes.it would undergo meiotic division to produce the half number of chromosomes,which is 39 chromosomes.this 39 haploid chromosomes are contained in the sperm cells or in the egg cells.
When the egg and sperm fuses,the diploid number of chromosomes is restored.
4 because if you have a infection it causes you not to breath properly
Answer: C. is less likely to be eaten by a predator.
Explanation:
The adult seven-spotted cockroach is the prey of various other insects including beetles so mimicking the pattern of a beetle would send a message that it is a beetle and because the chemical irritant that the beetle has makes it get avoided by others, the cockroach gets avoided by other insects too who don't want to be sprayed.
Of course this does not always work but it works for the most part and ensures the cockroach's survival.
Answer:
Le châtelier's principle states that if a stress is applied to a system in dynamic equilibrium, the system changes to relieve the stress.
Explanation:
This principle shows that when we change a system in equilibrium, it will seek to acquire a new state that nullifies this disturbance. Thus, there is a displacement of equilibrium, that is, a search for a new equilibrium situation, favoring one of the senses of the reaction. If it favors the direct reaction, with formation of more product, we say that the equilibrium has shifted to the right. However, it is said that it shifted to the left if the reverse reaction was favored, with formation of reagents.
