The hypothesis that all modern humans descended from an African lineage is supported by the mitochondrial DNA evidence. The Eve hypothesis is the hypothesis that is based on the study of mirtochodrial DNA; that modern humans have a common female ancestor who lived in Africa around 200,000 years ago.

Recovery from the 2008-2009 recession was agonizingly slow. what factors might have constrained faster growth?
Ann [662]
<span>Recovery from the 2008-2009 recession was agonizingly slow due to the following factors:
</span>

1. The recession had an impact on most of the industrialized West, not only the United States. As the recession spread to Europe, the United States's biggest market, it had a 360 degree impact on America's exports as well.


2. The US was spending a lot on the Iraq and Afghanistan wars. While this was theoretically supporting millions of jobs in the war industry, for the average person, there was no benefit. Billions that could have been used to help people, were used elsewhere.

3. Rising debt was also a problem. The recession opened up the hidden truth behind America's prosperity, the debt problem. Most people and institutions were spending war more than what they had and when the debt started to mount up, there was very little flexibility left.

4. We also have to admit that the response for the recession was too late. Firstly, the government should not have let a recession happen. However, once it did, they waited for Lehman brothers to completely fail before taking concrete actions.

Red blood cells,carrying dioxide(a waste product of cellular respiration) travel in the blood vessel to the lung; to get rid of
alexandr1967 [171]

Answer:

True.

Explanation:

Red blood cells or erythrocytes carry oxygen to the cells of the body so that they can have energy and function properly. This is not the only function of red blood cells. Also, they carry dioxide, which is a waste product that needs to be out of our body. Erythrocytes carry the dioxide to the lungs, specifically to the alveoli. In the alveoli due to the inhalation, oxygen enters our body traveling up to the lungs, specifically to the alveoli, where thanks to the thin wall of it as well as the one on the capillaries that are in contact with it, the dioxide enters the lungs to be expelled in the exhalation, and the oxygen is taken by the red blood cells to be used in the cellular respiration and generate energy to keep the vital functions of our body.
