Answer:

1. Circulatory System

2. Respiratory System

3. Endocrine System

4. Nervous System

5. Urinary/ Excretory System

Explanation:

1. Circulatory System- The heart pumps blood and blood vessels such as arteries and veins, transports the blood to every part of our body providing organs and muscles with nourishment.

2. Respiratory System- This system maintains our breathing. It supplies the body with oxygen for cellular respiration.

3. Endocrine System- The glands of the endocrine system secrete chemicals called hormones that regulate most of the processes in our bodies like growth, reproduction, metabolism, etc...

4. Nervous System- The entire nervous system controls all of the other systems of the body and it also transmits information to the brain, such as pain and external sensations.

5. Urinary/Excretory System- This system is responsible for eliminating waste products of metabolism and other materials from the body that are of no use.

How does adding more substrate effect an enzyme reaction<br><br>PLEASEEEE HELPPPP :(

marusya05 [52]

Increasing substrate concentration also increases the rate of reaction to a certain point. Once all of the enzymes have bound, any substrate increase will have no effect on the rate of reaction, as the available enzymes will be saturated and working at their maximum rate.

Genetic Mutations: Mastery Test: Which situation would be most likely to cause a DNA mutation? biology

frozen [14]

Answer:

B is correct. Production of PEP, glucose, and fructose 6-phosphate by gluconeogenesis-specific enzymes that bypass irreversible steps of glycolysis push the equilibrium of reversible enzymes that function both in glycolysis and gluconeogenesis in the direction of glucose production.

The Aye-Aye exhibits incomplete dominance for eye color. In a population of Aye-Ayes there are red-eyed individuals exhibiting t

VMariaS [17]

Answer:

196.8

Explanation:

In a population of Aye-Ayes there are red-eyed individuals exhibiting the dominant phenotype -----i.e RR

yellow-eyed individuals exhibiting the recessive phenotype ----- i.e rr

in the next generation, we will have the following offspring

R R

r Rr Rr

All the offspring are heterozygous in nature.

Now, the question goes further by saying, if there are 66 yellow-eyed individuals in the current population of 459, i.e (q² =66)

How many would be expected to exhibit the heterozygous phenotype in the next generation which will consist of 410 total individuals.

In solving Hardy-Weinberg question, we use the following equation below.

p + q = 1

p² + 2pq + q² = 1

where;

p = the frequency of the dominant allele

q = the frequency of the recessive allele

p² = the frequency of individuals with homozygous dominant phenotype

2pq = the frequency of individuals with heterozygous phenotype

q² = frequency of individuals with the homozygous recessive phenotype

Now, If In the next generation, the total population = 410

and q² (yellow-eyed individuals that are recessive in nature) = 66

then; q²= $\frac{individuals with recessive phenotype}{total population}$

q² = $\frac{66}{410}$

q² = 0.16

q = $\sqrt{0.16}$

q = 0.4

Since q = 0.4, we can easily get p by using the formula above:

p + q = 1

p = 1 - q

p = 1 - 0.4

p = 0.6

∴ Since we've known our p and q , we can easily determine how many would be expected to exhibit the heterozygous phenotype in the next generation.

2pq = 2 ( 0.6 × 0.4)

= 2 ( 0.24)

= 0.48

2pq = $\frac{individuals with heterozygous phenotype}{total population}$

0.48 = $\frac{x}{410}$

x = 0.48 × 410

x = 196.8 individuals
