Answer:
a. The embryo would suffocate or dehydrate.
Explanation:
Chorion is one of the four extraembryonic membranes that cover the embryo inside the egg. Chorion develops into the part of placenta-derived from the fetus.
Trophoblast develops into chorion during pre-embryonic development. Once formed, the chorion develops villi that are required for the exchange of material, specifically the respiratory gases, between the mother and fetus.
If an egg had nonfunctional chorion, the developing embryo will not get the supply of gases. In the absence of gas exchange between mother and embryo, the embryo will die of suffocation.
Chorion is also involved in the development of the placenta which in turn is the organ of the exchange of nutrients and gases and removal of toxic material.
Nonfunctional chorion would not support the placenta formation and the embryo will not get the supply of nutrients and water.
<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.

Answer:
The options are
A.Independent assortment
B. Mutation
C. Crossing over
D. Non disjunction
The answer is A.Independent assortment
Explanation:
Independent assortment of genes involves the separation of genes during the formation and development of reproductive cells.
A boy has XY chromosome and a lady has XX chromosomes. This explains why Sue inherited the mother's copy of chromosome 13 but their father's copy of chromosome 14 while her brother Billy inherited their father's copy of both chromosomes 13 and 14. He inherited both due to the presence of XY chromosomes.
No, and the environment also adds on to influencing traits.
