In certain rats, black fur is dominant over white fur, If two rats that are both heterozygous for fur colored are mated, what would their offspring be expected to have?

Answers

Answer:

Three different genotypes and two different  colors

Explanation:

Because both rats have heterozygous genes, meaning they have 2 different alleles, ex: "Yy") The offspring can have different genotypes and colors because the parents have heterozygous genes.

hope this helps!

The offsprings of the cross between two heterozygous rats will have the following genotypes: BB (black), Bb (black) and bb (white).

According to this question, a gene coding for fur color in rats is involved. The allele coding for black fur (B) is dominant over the allele for white fur (b).

If two rats that are both heterozygous for fur are crossed i.e. Bb × Bb, gametes B and b will be produced by both rats. Using this gamete in a punnet square (see image), the following offsprings will be produced: BB, Bb and bb.

BB - black offspringBb - black offspringbb - white offspring

Therefore, the offsprings of the cross between two heterozygous rats will have the following genotypes: BB (black), Bb (black) and bb (white).

Once pollen lands on the stigma, it forms a pollen ____________________ down through the long_____of the pistil [the female reproductive part] into the flower's ______– which contains ovules. fill in the blank

Answers

Answer:

1. Pollen tube

2. Style

3. Ovary

Explanation:

This process is describing the process of POLLINATION, which is the transfer of pollen grains from the anther of a male flower (androecium) to the stigma of the female flower (gymnoecium). After pollination i.e. the pollen has landed on the sticky stigma, the pollen grows out a tube called POLLEN TUBE.

The pollen tube extends through the STYLE of the female flower called PISTIL to the OVARY. The ovary is the reproductive part of the female flower that produces the ovules, which the sperm in the pollen is about to fertilize.

Glucose in the blood is taken up into your body's cells and used to produce a fuel molecule called adenosine triphosphate (ATP) through a series of complex processes known as cellular respiration.

2. Fats are known as being a long term energy source, and the fat on your body is used a "cushioning" for your bones.

how does the nervous system help the excretory system maintain homeostasis?

Answers

Answer:

The nervous system maintains homeostasis by controlling and regulating the other parts of the body. A deviation from a normal set point acts as a stimulus to a receptor, which sends nerve impulses to a regulating center in the brain.

Explanation:

The nervous system keeps the body in a state of homeostasis by controlling and regulating excretory system.

What is Homeostasis?In a broad sense, homeostasis refers to a system's stability or balance. It's the body's endeavor to keep its internal environment consistent. Internal environment stability necessitates regular monitoring and modifications as conditions change. Homeostatic control refers to the balancing of physiological systems within the body.

How does nervous system regulates homeostasis?Because the nervous system does not store nutrients, it must get them from the bloodstream on a regular basis. Any disruption in blood flow might result in brain injury or death.The nervous system keeps the body in a state of homeostasis by controlling and regulating the other organs. A variation from a regular set point stimulates a receptor, which transmits nerve impulses to a brain regulating area.

b. Photosynthesis uses light energy to convert glucose and carbon dioxide to oxygen and water.
c. Photosynthesis uses light energy to convert carbon dioxide and oxygen to glucose and water.
d. Photosynthesis uses light energy to convert carbon dioxide and water to glucose and oxygen.

Answers

Answer:- D

Photosynthesis used light energy to convert carbon dioxide and water into glucose and oxygen

The statement that best describes photosynthesis is statement d. As it converts carbon dioxide to glucose and oxygen.

Photosynthesis uses light energy to convert carbon dioxide and water to glucose and oxygen.During photosynthesis, plants, algae, and some bacteria convert light energy into chemical energy, stored in the bonds of glucose molecules.

The process involves the absorption of light by pigments called chlorophyll, which are present in the chloroplasts of plant cells and other photosynthetic organisms. Chlorophyll uses the light energy to drive the conversion of carbon dioxide and water into glucose and oxygen in a process called the Calvin cycle.

Thus, the correct option is statement D.

what was the problem with reusing contaminated water from other parts of the mill to extinguish the coke fires? From the book ‘When smoke ran like water’

Answers

Answer:

1. The problem with that was that the already poisonous water was made worse after using it to quench the flames from coke production.

2. It contaminated the soil, making it difficult for plants to grow.

Explanation:

As the author described the last stages of coke production, she explained that water was needed to quench the very hot flames from coke production. A 'bright fellow' suggested using dirty water from other parts of the mill to quench the flames from the coke production. The problems with this were;

1. The already contaminated water was made worse after it was used to quench the flames from coke.

2. Mrs. LaMendola noted that she was unable to grow her tomatoes in the path where the plumes from the oven ran. So the contaminated water negatively affected the soil.

The problem that should be already poisonous water is also made worse when it quenches the flames at the time when the production of the coke should be done.

Also, it contaminated the soil also it is difficult for growing the plants.

The problem of reusing contaminated water:

Since the author explained the last coke production stage so here the water required to quench that it should be very hot flames arise from the coke production. Also, the contaminated water should be worse whenever it is used for quenching the flames. Also, the contaminated water does not positively impact the soil.

A. Find test subjects for the new heart valve.
B. Conduct research on existing artificial heart valves.
C. Determine how to manufacture the new heart valve.
D. Evaluate the performance of the artificial heart valve.​

Answers

Answer:

C. Determine how to manufacture the new heart valve.

I think it seems a little obvious (I'm probably wrong)because obviously before doing something important your going to think about how to do it first.

The step in the design process that should the company perform before building a prototype of the heart valve is to determine how to manufacture the new heart valve. Thus, the correct option for this question is C.

What is meant by a Prototype?

A prototype may be defined as a sample, model, or liberation of a product that is significantly built in order to test a concept or process. This term is used in a variety of contexts, including semantics, design, electronics, and software programming.

A prototype is typically utilized in order to determine a new design to increase precision by system analysts and users. If an organization or individual wants to design any type of structural and functional unit, they must require to know its actual mechanism of it.

Then they are allowed to manufacture the concept with regard to their discovery. So, a research company requires to demonstrate how to manufacture the new heart valve with the help of a prototype.

Therefore, the correct option for this question is C.
