Answer:
When recombination occurs during meiosis, the cell's homologous chromosomes line up extremely close to one another. Then, the DNA strand within each chromosome breaks in the exact same location, leaving two free ends. Each end then crosses over into the other chromosome and forms a connection called a chiasma.
Explanation:
This blockage will likely increase the resistance to flow in his circulatory system, and as a result will decrease the rate of blood flow.
Blood vessels in the circulatory system transport blood away from and towards the heart. Arteries transport blood away from the heart, while veins transport blood back to the heart. The circulatory system transports oxygen, nutrients, and hormones to cells while also removing waste products such as carbon dioxide.
Vascular disease (vasculopathy) affects the blood vessels that transport oxygen and nutrients throughout your body and remove waste. Plaque (made of fat and cholesterol) slows or blocks blood flow inside your arteries or veins, causing common vascular problems. When there is too much cholesterol in the blood, the cholesterol and other substances can combine to form deposits (plaques) on the artery walls. Plaques can cause an artery to narrow or become blocked.

Answer:
1. warm blooded, 2. breast feed its young
Explanation:
Whales are warm blooded, which means they keep a high body temperature that does not change in the cold water. Fish are cold-blooded, so their body temperature changes depending on the temperature of their environment. AND hales are other mammals that feed their young milk too, although it takes plenty more to feed them than human babies
Answer:
Scientists have long known that rocks naturally absorb carbon dioxide over thousands of years by binding it with minerals to form solids like calcium carbonate, a common substance found in rocks and the main component of snail shells and eggshells.
