Answer:
The correct answer is Glycogen and Fat.
Explanation:
When there is a calorie intake that is more than the burned calories, the short term solution our bodies execute is to turn glucose into glycogen and store it in the liver. And in the long term glucose is turned into fat which is then stored in cells named adipose. I hope this answer helps.
1. The correct answer is: The viral envelope proteins interact with CD4 and a co-receptor on the cell membrane.
Binding and entering the host cell are the first steps of the HIV virus infection. So, these steps play a major role in determining the ability of HIV to degrade the human immune system. Binding of HIV to CD4+ T lymphocytes (express chemokine receptors CCR5 and CXCR4 called co-receptors) triggers the fusion of the viral and host cell membranes, initiating infection (viral core gets into the cytoplasm).
Attachment of the virion can be:
• Nonspecific-envelop protein of the virus (Env) binds to cell-surface heparan sulfate proteoglycans
• Specific-Env binds to integrin.
2. The correct answer is: Activation of the host cell by cytokines, growth factors, or antigens.
After the viral capsid enters the cell, single-stranded RNA genome is released from the attached viral proteins and copied it into a complementary DNA (cDNA) molecule thanks to an enzyme called reverse transcriptase. Next step is the integration of the viral DNA into the host cell's genome. This process is done by another viral enzyme called integrase. The integrated DNA is transcribed into RNA and then translated into proteins that will help the package of new viruse particles.
3. The answer is: false
Reverse transcriptase is an enzyme that catalyzes the formation of DNA from an RNA template. Since the genome of the virus (HIV) is single stranded RNA, reverse transcriptase copies it into a complementary DNA (cDNA) molecule. Thanks to this enzyme, formed cDNA can be integrated into host’s genome. Because of this proprety, antiretroviral drugs used to treat HIV infection work as reverse-transcriptase inhibitors.
Answer: Like fats, they are typically composed of fatty acid chains attached to a backbone of glycerol. Instead having three fatty acid tails, however, phospholipids generally have just two, and the third carbon of the glycerol backbone is occupied by a modified phosphate group.
If one parent has been affected by sickle cell anemia, while the other parent does not and is homozygous, the chances that a child will have this disorder is 0%. Thus, the correct option is C.
<h3>What is Sickle Cell anemia?</h3>
Sickle Cell anemia may be defined as a genetic disorder that is caused by a recessive allele. It is an inherited disease in which the red blood cells have an irregular crescent shape, obstruct small blood vessels, etc.
This disease is inherited when both genes of each parent are supposed to be defective or carriers. While in this case, only parents are affected by the disorder while the other is homozygous for the normal allele.
In this condition, all the offspring produced by both parents remain as carriers but not affected ones.
Thus, the correct option is C.

Answer: A protoplanetary disk.
Explanation:
The first thing that was formed, is the Sun, where most of the mass collapsed by the gravitational force and formed the star in the center.
After that, the rest formed something called a "protoplanetary disk", which is a rotating disk (as the name implies) of dust and dense gas which rotates around a newly generated star (in this case, there are protoplanetary disks formed around other types of stars, like a T Tauri Star).
Now, this protoplanetary disk will evolve into a planetary system, (planets, asteroids, moons, etc)
