1. Because they are unstable and can share electrons in their outer energy levels.
2. Polar molecules occur when there is an electronegativity difference between the bonded atoms. Nonpolar molecules occur when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out.
Answer:
(A)
Explanation:
In question number one, it is important to understand that during exercise, the oxygen hemoglobin dissociation curve shifts to the right. This is also confirmed by the fact that the patient, Kira is also breathing slowly. CO2 builds up in the both as patients begin to hypo ventilating. Most likely this patient in in a state of respiratory acidosis. But, it is important to understand that when the curve shifts to the right in this situation, you have decrease affinity of Hb for O2, meaning that the O2 does not want to bind to the hemoglobin. It instead is gonna wanna go straight to the tissues so that the tissues can get oxygen during high exercise states like this one. If the tissues don't get oxygen then you would have elevated lactic acid production in the tissue and the body would go into a sever state of lactic acidosis. So during excercise and increased CO2 content in the blood due to hypoventilation post excercise, our body's natural mechanism is to dump all the oxygen we get directly to our tissues and bypass the hemoglobin that is circulating in our vessels. So that being said you should be able to answer the question above. The hemoglobin would be less saturated with o2 in this case.

1. The answer depends on your picture.
DNA is packed and condensed with proteins in the form of chromosomes.
Since the process of division is going to start that means each chromosome will have an X shape. They had the DNA content copied once (in the S phase). The original, plus the copy created, form the X.
You just have to count the number of X's in the picture.
2. The answer is 4 nuclei.
Since the process of division happening is meiosis, that means that four new cells will be originated from a cell that's dividing.
So, four new cells each one with a nucleus, that means 4 nuclei in total.
If this was mitosis, only 2 new cells would be formed which means 2 nuclei
3. The number of chromosomes depends on your picture/exercise.
The answer would be half of the number of chromosomes that you started in the meiosis 1.
This time, chromosomes won't have an X shape since the copies were separated. At the end of the process, each chromosome has just one chromatid.
Answer:
0% or 100%
Explanation:
Because when you put it out onto a table you only get the combination black and white so there could be a chance of either
