Answer:

Yes.

Explanation:

I will put the enzymes of the citric acid cycle in this organism so that in the absence of sunlight, it also produces energy to grow quickly. Citric acid cycle is a series of chemical reactions which release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins. This cycle is also called Krebs cycle so incorporation of this cycle is good for the organism.

Answer:

If the gamete will get either G or g, the probability will be 1/2 of getting G.

Explanation:

all question 3 answer is that. Because all 3 of question are same. only repeated three times

In a parent pea plant with the allele pair Gg, the probability that one gamete will contain the G allele is 0.5. This is because there are two possible outcomes in which one must definitely fall. So, it is 1/2.

Alleles may be characterized as the alternative form or versions of a gene that are responsible for particular traits in living organisms. They carry a code of genetic sequences within generations.

In a parent pea plant with the allele pair GG, the probability that the gamete will contain the g allele is zero. This is because there is no presence of allele g that can be determined within any gametes. So, it is not possible to get g in the pair allele of GG.

In a parent pea plant with the allele pair gg, the probability that one gamete will contain the g allele is 1 or 100%. This is because both carry g alleles. So, the probability is 100%.

The sympathetic nervous system is responsible for the mouse's physiological state.

The nervous system divides into the central nervous system and peripheral nervous system.

In the central nervous system, we have the brain and the spinal cord.

The peripherical nervous system, which is all the nerves that are not in the spinal cord or the brain, is divided into:

-Sympathetic nervous system. It is the one that works under stress. It gives the fight or flight response preparing the body for a dangerous situation. It increases the heart rate and epinephrine's release. Epinephrine is a hormone that helps in this response stimulating the sympathetic system.

-Parasympathetic nervous system. It is the one that works in calm situations, like after we ate, regulating digestion, and trying to save energy for any upcoming event.

In conclusion, as there is an increase in epinephrine and heart rate, and the mouse is "fighting" against a scorpion, the nervous system division responsible for this physiological state is the sympathetic nervous system.

Vitamins and minerals boost the immune system, support normal growth and development, and help cells and organs do their jobs. For example, you've probably heard that carrots are good for your eyes. It's true! Carrots are full of substances called carotenoids (pronounced: kuh-RAH-teh-noydz) that your body converts into vitamin A, which helps prevent eye problems.

Vitamin K helps blood to clot, so cuts and scrapes stop bleeding quickly. You'll find vitamin K in green leafy vegetables, broccoli, and soybeans. And to have strong bones, you need to eat foods such as milk, yogurt, and green leafy vegetables, which are rich in the mineral calcium.

The answer is D, The U.S Public Health Service Policy. Its main purpose was providing protection for human subjects for research work which was conducted by federal agencies. You can read more about it on HHS.gov, as it is a very interesting regulation.

I hope this helps! :)

Issued in 1974, 45 CFR 46 raised to regulatory status US Public Health Service Policy. Option D

The restrictions known as the Common Rule for the protection of human subjects in research done by or supported by federal agencies are outlined in Title 45 of the Code of Federal restrictions, Part 46. These laws define moral principles and requirements for the protection of research subjects who are being used as human subjects.

The US Public Health Service (PHS) published the policy that would eventually become 45 CFR 46 in 1974. This policy established standards for the examination and approval of research involving human subjects as well as the legal foundation for the protection of those individuals. Informed consent, weighing risks and benefits, and the creation of Institutional Review Boards (IRBs) to regulate research techniques were all adopted.

Answer:

1) The purpose of mitosis is growth and repair of cells

Explanation:

Prophase:

-DNA condenses (supercoiled, chromatids are visible under light microscope);

-Nuclear membrane begins to disintegrate (by the end of prophase  it is completely gone)

-Centrioles move to opposite ends of the cell

-Splinde fibers start to form from the centrioles and grow

Metaphase:

-Spindle fibers, departing from both poles, are attached to each centromere, on opposite sides

-The spindle fibers pull the chromosomes back and forth until they align in a plane along the equator of the cell, which is called the equatorial plane

Anaphase:

-The spindle fibers shorten

-The centromeres of sister chromatids split

-Chromatids move apart, pulled by the spindle fibers

-Chromatids become chromosomes

-Half of the chromosomes move to one cell pole, half to the other

Telophase:

-The chromosomes reach the cell pole

-Nuclear membrane reforms

-Spindle fibers break down and disappear

-The chromosomes begin to uncoil, which makes them diffuse and less compact

Cytokinesis:

-The cell membrane pinches inward until the cell divides in two;

-There are two daughter cells with the same structures and number of chromosomes as the parent cell

-Chromosomes decondense

Carbohydrates may be defined as energy-rich foods such as sugars and starches. if consumed in excess or not properly metabolized in the body, carbohydrates may lead to obesity and which may also lead a person to severe number of diseases.

Chitins are components of the exoskeletons of foods such as shrimps, crabs and snails, and insects.

Chitin's use as a component in healthy foods is based on its health benefits.

For example it promotes weight loss , prevents obesity, relieving constipation and preventing inflammation associated with refined carbohydrates, cookies and candies

Answer:

When certain large molecules are unable to move through the membrane without the help of channel proteins

Explanation:

Facilitated diffusion occurs when large molecules that are unable to pass through a membrane on their own make use of channel proteins to move from one side of the membrane to the other. Facilitated diffusion can occur when a liquid on one side of a membrane has a higher osmotic pressure than a liquid on the other side of the membrane, but it isn’t a required feature of facilitated diffusion. Similarly, facilitated diffusion can occur when there’s a large membrane potential present, but it isn’t a required feature of facilitated diffusion. Facilitated diffusion doesn’t require the use of energy, so the presence of ATP is irrelevant to facilitated diffusion occurring.

Answer:give me brainliest

Explanation:

A combination of the Q wave, R wave and S wave, the “QRS complex” represents ventricular depolarization. Ventricular depolarization occurs in part via an accessory pathway (AP) directly connecting the atrium and ventricle and thus capable of conducting electrical impulses into the ventricle bypassing the AV-His Purkinje conduction system.This term can be confusing, as not all ECG leads contain all three of these waves; yet a “QRS complex” is said to be present regardless.

Answer:

28 × 10⁶ colonies/ml

Explanation:

Let C be the concentration of bacterial in the initial stock. When it is diluted by a factor of 10⁶, the new concentration is C' = C/10⁶.

When 2 ml of this concentration is spread on a Petri dish of solidified media, 56 colonies were produced. The number of colonies, n after spreading the 2 ml of C' is C' × 2 ml = 2C' = 2C/10⁶.

So, n = 2C/10⁶.

Since the number of colonies after spreading on a Petri dish of solidified media is 56, n = 56 colonies.

So, 2C/10⁶ = 56

Making C subject of the formula, we have

C = 56 × 10⁶/2

C = 28 × 10⁶ colonies/ml

So, the initial concentration of bacteria is 28 × 10⁶ colonies/ml

From left to right, the correct order of the minerals from the least hard to the hardest is ⇒ Graphite, Talc, Gypsum, Calcite, Fluorite, Apatite, Magnetite, Pyrithe, Feldespat, Quartz.

Theoretical frame:

Hardness is one of the physical properties of minerals and is a significant one when identifying and recognizing them.

Hardness measures the resistance level of a surface to abrasion. In the specific case of minerals, it measures how minerals resist being scratched or penetrated.

The hardness level is determined by an attempt to scratch or produce a mark on an unmarked surface using sharp elements, such as nails, copper coin, glass, or a steal knife. Notice that these elements also vary in their hardness.

There are different methods used to define hardness, and they are not comparable to each other. The Mohs hardness method defines an ordinary qualitative scale that characterizes the mineral according to their resistance to being scratched by a harder element.

According to the Mohs hardness scale, the level in which the given minerals are placed is as follows,
