1 AU means 1 astronomical unit or the aproximate distance from the earth to the sun
1AU=<span>149597870.7 kiometers
1 billion=1,000,000,000
600 billion=600,000,000,000
</span>
<span>x times 1AU=600,000,000,000
x times </span>149597870.7=<span>600,000,000,000
solve for x
divide both sides by </span><span>149597870.7
</span>x=4010.75
so aprox 4011 AU's
Teens need protein for many reasons, including building and repairing muscles, promoting hair and skin health, fighting off infections and carrying oxygen in the blood. Proteins also help with building enzymes, hormones and vitamins, especially important for adolescents. Proteins are made up of building blocks called amino acids, most of which your body can naturally produce. However, there are nine essential amino acids that your body cannot make, but that you can get through foods you eat. It is important for teenagers to consume a variety of proteins so their bodies get proper nutrients for growth and development.

Answer:
Explanation:
The primates have a hand feature which increases their fitness in the tree environment are the opposable thumbs. The thumbs are the broadest digit of the hand. The thumb can move in different directions in comparison to the other digits of the hand. This is an advantage in primates to hold and grasp the objects with their hands.
The monkeys climbing on the trees grasp the branches of trees to move from one tree to another.
Answer:
A. S phase
Explanation:
The cell cycle involves all the series of division events that occurs to an organism. Cell division, which can be meiosis or mitosis, involves two main stages viz: Interphase and M phase.
Interphase describes the resting stage of the cell i.e. when the cell is not dividing. The cell uses this time to prepare itself for the next round of division. Interphase stage further consists of three main phases viz: G1, S and G2 phases.
In the S phase or synthesis phase of Interphase, the cell duplicates its genetic material (DNA). Hence, an onion cell observed by a student to have loosely coiled chromatin depicting DNA duplication is in the S-PHASE.
