Answer:
1. 128
2. 16,384
Explanation:
Imagine there were two pairs of chromosomes:
A paired with B
C paired with D
A gamete could have the following combinations:
A + C
A + D
B + C
B + D
Therefore, with two pairs of chromosomes, there are 4 (2²) possibilities
With seven pairs of chromosomes, there are (2⁷) possibilities. 2⁷ = 128
For a zygote produced by two barley parents, there are two gametes fused. So we must multiply the number of combinations for each gamete. Therefore, number of possible genetic combinations is 128 x 128 = 16,384
When assessing a client's fluid and electrolyte status, the nurse recalls that the regulator of extracellular osmolarity is sodium.
<h3>What is osmolarity?</h3>
- Osmolarity is the measure of the amount of solute present in a solution.
- It is also known as osmotic concentration.
- It is expressed as Osmol/liter or OsmL.
- Osmolarity determines the extent to which a particular solution is concentrated.
Thus, when assessing a client's fluid and electrolyte status, the nurse recalls that the regulator of extracellular osmolarity is sodium.

The four factors that affect evolution are mutations, natural selection, genetic drift and the gene flow, In the case, if the ground finches that Grants studied, we can observe the working of the natural selection. Due to change in the conditions in the environment, the large beak was an advantageous trait that was favored by the natural selection. The result of this process was an increase in numbers of large beaked finches and decrease in small-beaked finches compared to the initial numbers in the population.
I think it’s the first one
1. Oxidized
2. Reduced
3. Glucose
4. Pyruvate
5. NAD+
6. NADH
An acronym for understanding gain and loss of electrons is OIL RIG (Oxidation is Loss of electrons, Reduction is Gain of electrons).
