Answer:
0.08, because for an X-linked trait the genotype frequencies among males are the same as the allele frequencies. Therefore, you would expect about q2 = 0.0064 (or 0.64%) of the female population to be affected and 2pq =0.147 (or 14.7%) of the female population to be carriers.

A rabbit breeder has rabbits that exhibit three different coat colors: dark gray, chinchilla (a lighter gray), and albino. When cross breeding rabbits with these different coat colors, he finds that dark gray is dominant to chinchilla and albino, whereas chinchilla is dominant to albino. These phenotypic outcomes indicate that there are more than two alleles of rabbit coat-color genes and that they exhibit
Answer:
Multiple allelism
Explanation:
Multiple alleles occur whereby three or more alternative form of a gene which in this case study are dark gray, chinchilla (a lighter gray), and albino; are all present at a locus but only two of the alleles can be present in just one organism.
Process at the nephron
Answer:
The concentration of solutes is different in glomerulus, glomerular filtrate and urine is different because with time to time, the useful solutes are absorbed to the blood thus the concentration of useful solutes (that can be used by the body) goes on decresing in the glomerulus. After that, the unwanted solutes (most of which is Urea) remain at the end and are expelled out of the body.

B. A one-celled organism that does not have a cell wall.
C. An organism whose cells each have a cell wall.
D. A one-celled organism that does not have a membrane-bound nucleus.
Answer:
d
Explanation:
prokaryotes are characterized by not having a membrane bound nucleus and vise versa for eukaryotes.
Answer:
D. A one-celled organism that does not have a membrane-bound nucleus.
Explanation:
Prokaryotes are unicellular organisms that have a cell wall that surrounds the plasma membrane and gives the organism shape. It also does not have a membrane-bound nucleus to hold its chromosomes. The chromosomes of a prokaryote is found in a nucleoid, which is a part of the cytoplasm.

The air behind a cold front is cold and dry.
Please select the best answer from the choices provided
OT
OF
Answer:
True
Explanation:
The air behind a cold front is cold and dry. This is true because the cold front has a cooler mass of air which is usually cold and dry and it replaces at ground level a warmer mass of air.
This cycle continues and results in evaporation and precipitation and helps in balancing the atmosphere.
Gastroparesis is a condition that causes a partial paralysis of the stomach. The stomach has reduced ability to contract to move food through the digestive system. Some common symptoms of gastroparesis are abdominal pain, nausea, and feeling full after eating a small amount of food. What would be the most likely cause of this condition? A. damage to nerves that control the stomach B. lack of pancreatic juices and bile C. lack of enzymes in the small intestine D. damage to the mucus lining of the stomach
Symptoms of this condition include paralysis of the stomach muscles. Muscles are controlled by nerve impulses, therefore the most likely cause for this condition is (A.) damage to nerves that control the stomach
B. lack of pancreatic juices and bile -> this will lead to food not being chemically brokend down properly in the stomach and oils not mixing with water leading to malnutirion
C. Lack of enzymes in the small intestine -> this will also lead to food not being chemically digested and malnutrition

Which describes an effect that ocean currents have on short-term climate change?
A)Ocean currents increase the strength of prevailing winds, which can cool the air and land.
B)Ocean currents can carry cold water, which can cool the air and land.
C)Ocean currents increase hurricane activity, which can raise the temperature of the air and land.
D)Ocean currents can carry warm water, which causes hurricane activity and raises the temperature of the air and land.
Answer:B)
Explanation: Our oceans cover more than 70 per cent of the Earth's surface And can do much more things.
In an ecosystem, ocean currents carrying cold water, which can cool the air and land describes an effect which has a short-term climate change.The correct option is B.
An ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact with each other. The abiotic and biotic components are linked to each other through the nutrient cycles and flow of energy.
Energy enters the ecosystem by the process of photosynthesis .Animals play an important role in energy transfer by feeding on each other.As a result of this transfer of matter and energy takes place through the system .Within an ecosystem, climate changes are greatly influenced by the ocean currents carrying cold water, which are able to cool the air and land.
Thus, the correct option is B.

What happens to the molecules of a substance when heat is added to it ?
Answer:
The molecules start to energize.
Explanation:
When you heat up any molecule, the atoms and molecules start to vibrate more energetically. When this happens, it increases the space in-between the atoms. The substance expands and takes up more space as atoms move faster and farther away.

The researchers participating in the experiments described above were assigned to conduct new experimentation, also on Leigh syndrome-positive mouse specimens. As a precursor step, it was decided to create a new population of Leigh syndrome-positive mice. What would be the option most likely to be successful in creating this population
Answer:
Induction of intentional mutations in the mitochondria of pre-fertilization ova
Explanation:
Leigh syndrome is a neurological disorder which affects the motor and mental state of organisms. The Mitochondria is known as the power house of the cell due to its production of energy for use by various cells in the body. Most neurological problems affect the motor and mental state as a result of a mutated mitochondrion. This explains why Induction of intentional mutations in the mitochondria of pre-fertilization ova Is correct.

A population of fish has 11,140 individuals. They have a death rate of 100 per year and a birth rate of 120 per year. Assuming 50 fish migrate into the population and 25 migrate out of the population per year, how many individuals would there be after the first year
Answer:
11,185 individuals
Explanation:
The number of individuals after the first year would be 11,185.
The change in the number of individuals in a population or population size is determined by the equation:
(B - D) + (I - E), where B = birth rate, D = death rate, I = immigration, and E = emigration.
In this case, B = 120, D = 100, I = 50, E = 25. Hence, change in the population size;
= (120 - 100) + (50 - 25) = 45
This thus means that the population would have increased by 45 individuals after the first year. Since there were 11,140 individuals initially, the total number of individuals after the first year would be;
11,140 + 45 = 11,185 individuals.

Which statement best describes the cycling of carbon between the atmosphere and geosphere? Precipitation and condensation increasing the groundwater supply Glaciers melting due to an increase in global climate temperatures Volcanic activity releasing carbon into the atmosphere Trees and plants releasing carbon through respiration
Answer:
Volcanic activity releasing carbon into the atmosphere
Explanation:
In the geosphere, carbon enters when the dead and decaying matter takes the form of fossil fuels. From the biosphere, the carbon enters into the geosphere through these sources. A carbon reservoir is maintained in the geosphere through these sources. The process of weathering, erosion, and volcanic eruption exposes the carbon content of the geosphere into the atmosphere. Volcanic eruptions upturn the carbon content of the geosphere and expose them.

Volcanic like the answer above

A population of 40 killer whales lives in a bay that measures 2000 square miles. What is the population density of killer whales?
Answer:
.02
Explanation:
When finding population density, divide the amount of people, animals or things in the region by the total square miles. 40/2000 is .02.
A population is the size of the group of individuals residing at a place. A population of 40 killer whales has a population density of 0.02.
What is population density?Population density is the individual's concentration of a specific species at a particular geographical location. It allows the establishment of the ecosystem and health.
Given,
Number of individulas = 40
Size of the area = 2000
Density = Number of individuals ÷ Size of the area
= 40 ÷ 2000
= 0.02
Therefore, 0.02 is the population density of killer whales.
