I can’t help you with the first two questions, as I do not have a reference, but I can help you with the last two. Cystic fibrosis is a recessive trait. It is caused when specific sections of both copies of chromosome 8 are deleted, which in other words mean that it is not a sex-linked disorder because it isn’t inherited from the mother and father of the offspring.
No, all mutations are not bad. Only a small amount of mutations cause genetic disorder. Some in fact are good mutations. There is actually one mutation that is found roughly in 10% of Europeans which affects the CCR5 protein and it prevents HIV from entering the cell!
Answer:
The correct answer will be- 30 percent
Explanation:
Pregnancy loss or miscarriage is the natural death of the fetus or the embryo due to which the growing embryo is unable to survive.
About 70-80% of the miscarriage occurs between the first trimester or first 12 weeks of the pregnancy.
About 30-40% of all fertilized eggs get miscarried before pregnancy is known that is before implantation, 30% following implantation but prior to the missed period and 10% due to clinical miscarriage.
Thus, 30 per cent is the correct answer.
<span>D. There would be much less precipitation and evaporation.
Much of the precipitation comes from the evaporation of water from the ocean and posterior condensations into clouds that go over the mountains. If the mountains were to be far from the ocean, there would be much less precipitation and, therefore, evaporation also. </span>
Answer:
Hydrolysis reactions use water to breakdown polymers into monomers and is the opposite of dehydration synthesis, which forms water when synthesizing a polymer from monomers. Hydrolysis reactions break bonds and release energy.
Answer:
Animals, plants, fungi, and protists
Explanation:
Animals, plants, fungi, and protists are examples of Eukaryota organisms. Animal and plant cells contain many of the same kinds or organelles. There are also certain organelles found in plant cells that are not found in animal cells and vice versa.
