3) Hormones which are proteins play important role in the regulation of metabolic reactions inside the cell

4)  Regulation of cell division is performed by DNA-associated proteins  

5)  Proteins plays important role in storage of iron inside the cells

How are babies born describe in order?
Alex Ar [27]
The mother and father will have intercourse, and run the chance of the sperm reaching the egg.

The mother will go through a period of around 9 months (The time varies with each person), but at least 8 months. There are three trimesters of pregnancy and they all about 13 weeks long each.

By around week 5, the baby is already developing rapidly, and by week 16, the weight of the baby will skyrocket, nearly doubling its size and weight. Week 20 and your baby will begin to move a lot more than usual and has already developed to the point where it can make expressions and move its arms and legs by week 40, your baby is almost completely developed, has started practicing breathing, and the mother will be suffering through mood swings, cravings, and cramps. 

Labor consists of three stages. There is no real starting point for labor, but you will know when it starts at the beginning of contractions, and your cervix starts to dilate. That is Early Labor.

Active Labor is more painful, and the dilation of your cervix is more rapid, this is around the end of the first stage and the beginning of the second stage, or the pushing phase. You will begin to push the baby out. This phase ends with the delivery of the baby. The final stage, the third stage, is the delivery of the placenta. After that, you are done. 

Something to keep in mind: Your water "breaking" is the rupture of your <span>fluid-filled amniotic sac. It may rupture before labor and will give you a warning of the start of your labor, OR you are so far underway into labor, that you don't feel it break.</span>

Suppose that you performed a cross of a wild type strain of Neurospora to a strain with a defective synthesis of the amino acid
o-na [289]

Answer:

<h2> 1/2</h2>

Explanation:

Given;

Cross between a wild type stain of Neurospora  and mutant stain.

Wild type can grow on minimal medium too.

Mutant strain is defective in synthesis of tryptophane amino acid. So, mutant strain can grow only in complete medium, and it can not grow on minimal medium, while wild type can grow in both mediums.

So after crossing both stains, half spores get defective gene while half get normal gene, so 1/2 or 50% proportion can  grow on minimal medium.
