Explanation:

Its stomach was filled eith 30 plastic bags, and many smaller pieces of plastic. ... The whale was emaciated, and scientists believe that the plastic had gathered in such an amount in its stomach that it had created a plug, stopping the digestive process.

The cause of death appears to be starvation, though that's under investigation. Many of the stranded whales in 2019 have been malnourished, said David Weller, a research wildlife biologist with NOAA's Southwest Fisheries Science Center in La Jolla, California.

Answer:

It's because whales do not naturally chew and swallow they suck in their food.

Which statement about positive feedback regulation is accurate?
GenaCL600 [577]

Answer:

Answer is B. Positive feedback regulation can generate an abrupt, all-or-none response in which the cell moves from ignoring a signal to responding to it very strongly.

Explanation:

Positive feedback can be described as an example of feedback, which is a natural mechanism that amplifies the action of a system.

It can be better be explained further, as a situation whereby the blood pressure decreases and the response of the body also makes or causes the blood pressure to decrease the more.

Other examples of a positive feedback also include blood clotting, ripening of fruits , uterus muscle contraction, resulting to the stretching of the uterus during pregnancy.

A zonkey comes from a zebra(46 diploid chromosomes) and a donkey (62 diploid chromosomes).
MAVERICK [17]
Q1. The answer is 53 chromosomes

Zebra has 44 diploid chromosomes (2n = 44). Zebra's gametes are haploid, so they will have 22 chromosomes (n = 22).
Donkey has 62 diploid chromosomes (2n = 62). Zebra's gametes are haploid, so they will have 31 chromosomes (n = 31).
After fusion of zebra's gamete (n = 22) and donkey's gamete (n = 31), the zonkey's zygote will have 22 + 31 = 53 chromosomes


Q2 and Q3. In the meiosis, the number of chromosomes is reduced by half. Since zonkey has 53 chromosomes, after meiosis it should have 53/2 chromosomes, which is not the whole number. This is the reason why they cannot produce normal gametes that will result, after the fusion, in the production of normal diploid zygote
