Explanation:

Multiple sequence alignment is a method that can be used to compare three or more biological sequences to determine homology and evolutionary relationships between species. This is done by selecting a target protein or DNA sequence (consensus) and comparing it across other species’ sequences. Conservation is a statistical analysis that describes how much the target sequence is observed across the selected group of species. A higher conservation score indicates that the protein or gene is more ancient or more critical across species.

Your lungs take in air through the mouth and nose. Explain how the lungs function in the human body.

A) They coordinate the movement of the heart.
B) They pass oxygen from the air into the blood.
C) They pump the blood throughout the body.
D) They remove carbon dioxide from the air.

Answers

Answer:

Your answer would be "B) They pass oxygen from the air into the blood."

Explanation:

They certainly don't coordinate the movement of the heart, so A isn't an option.

The lungs also don't pump blood through the body, that's the hearts job.

And the lungs do not filter carbon out of the air, which eliminates D.

Therefore your answer is B.

The lungs function in the human body by passing oxygen from the air into the blood.

Gaseous exchange in the lung

Gaseous exchange happens in the lung of humans. Oxygen is exchanged for carbon dioxide.

A mixture of air is taken through the mouth and the nose into the lung. On getting to the lung, the oxygen in the air dissolves on the surface of the lung and enters the blood by diffusion.

In exchange, carbon dioxide in the blood diffuses in the opposite direction and is breathed out.

Distinguish between Diet and Nutrition

Answers

Answer:

Diet is limiting oneself in foods and calories for several days or weeks. As a result, overweight is rapidly leaving, but once you return to your previous lifestyle, as extra pounds return, and getting rid of them becomes more difficult.

Proper nutrition is a complete balanced everyday diet, in which all necessary products must be present: meat, cereals, dairy products, fruits, vegetables. Eating healthy and balanced all the time not only strengthens the body but also helps to lose weight. It is known that an organism that does not regularly receive all the necessary substances begins to "junk".

please mark as brainliest ..... thank you!

[tex]\huge{\mathbb{\tt { What \: is \: Diet?}}}[/tex]

In nutrition, diet is the sum of food consumed by a person or other organism. The word diet often implies the use of specific intake of nutrition for health or weight-management reasons. Although humans are omnivores, each culture and each person holds some food preferences or some food taboos.

[tex]\huge{\mathbb{\tt { What \: is \: Nutrition?}}}[/tex]

Nutrition is the biochemical and physiological process by which an organism uses food to support its life. It includes ingestion, absorption, assimilation, biosynthesis, catabolism and excretion. The science that studies the physiological process of nutrition is called nutritional science.

[tex]{\boxed{\boxed{\tt { Difference \: between \: Diet \: and \: Nutrition}}}}[/tex]

The main way of getting nutrition is by having a proper diet. Diet comprises of different foods, which contain nutrients. When the foods are ingested, nutrients are absorbed by the body. Body uses them in different metabolic activities. A poor diet will result in a poor metabolic efficiency. Finally, it may lead to nutrient disorders or unbalance nutritional conditions in human body.

In pea plants, peas can be green or yellow in color. Assume that green peas are dominant to yellow peas. Is it possible for two plants with green peas to produce any offspring with yellow peas?
vocabulary words to use in response: dominant allele, recessive allele, , heterozygous, genotype, phenotype

Answers

Answer:

No.

Explanation:

Turns out they have yellow peas because the yellow version, Y, is dominant over the recessive green version, y. Y always wins out over y: When a pea plant makes seeds, only one of its two copies of the color gene goes into the seed. So if you have two green pea plants, each can only pass a green version.

Answer:

No.

Explanation:

Turns out they have yellow peas because the yellow version, Y, is dominant over the recessive green version, y. Y always wins out over y: When a pea plant makes seeds, only one of its two copies of the color gene goes into the seed. So if you have two green pea plants, each can only pass a green version.

Determine if the following statement is true or false, and why. “Everyone who
carries a faulty allele develops a disease."
A. False, it should read, "No one who carries a faulty allele develops a disease."
B. False, it should read, "Some people who carry a faulty allele develop a disease, some
are carriers."
C. True
D. False, it should read, "No one who carries a faulty allele becomes a carrier."

Answers

B.False. it should read, “Some people who carry a faulty allele develop a disease, some are carriers “

The statement "Everyone who carries a faulty allele develops a disease" is absolutely false. This is because some people who carry a faulty allele develop a disease, some are carriers. Thus, the correct option is B.

What is an Allele?

An allele may be defined as one or two or more alternative forms of a gene. An individual always inherits two alleles, one from each parent that shows characteristic traits for any given genomic location where such variation exists.

If the two alleles are the same, the individual is homozygous for that allele. While, if the two alleles are non-identical, the individual is heterozygous for that allele.

It is not possible that everyone who carries a faulty allele develops a disease because it depends on the expression of the disease, whether it is dominant or recessive, sexual or autosomal, etc.

Depending on the same principle, some are affected by the disease when both alleles have the same traits while some are carriers.

Therefore, the correct option for this question is B.

Which ACTN3 genotype (RR, RX, or XX) would provide these Olympic marathon athletes with an advantage, and why?

Answers

Answer:

XX

Explanation:

ACTN3 genotype i.e. XX provides advantage to the Olympic marathon athletes because it strengthens the fiber of the muscles. This gene is also called the gene of speed. This ACTN3 gene has a great influence on the type of fiber that makes body muscles, and they are also linked to strength and endurance so we can conclude that this gene provides benefits to the Olympic marathon athletes by giving strength to the fiber of muscles.

ACTN3 genotype is the gene encoding for the actinin of the skeletal muscle fibres.  XX of the ACTN3 genotype will be advantageous for marathon athletes.

What is ACTN3 genotype and XX?

ACTN3 genotype is the gene encoding for the protein of the skeletal muscles fibres that are associated with muscular performance.  This protein is expressed in the myofibers with a high twitching ability and result in a high-velocity force.

The XX genotype provides strength to the muscles and is the gene coding for the proteins that give speed. They are also responsible for endurance and are beneficial for athletes.

Therefore, XX of the ACTN3 genotype is advantageous for athletes.

explain the differences between the particles of a pure substance and the particles of a mechanical mixture

Answers

Answer:

A substance is pure if it is a single substance, and it is made up of only one type of particle. If there is more than one substance, and therefore more than one type of particle, it is a mechanical mixture, the particles can be easily distinguished, due to their non-uniform composition. The composition of a mechanical mixture is variable and their components may be separated by physical or mechanical means because they are not chemically bound.

Explanation:

A pure substance is one that has a composition and characteristic properties that do not change, whatever the physical conditions in which it is found; that is, the physical transformations do not affect it. In other words, pure substances will be made up of particles that are identical to each other. Mechanical mixture are the result of the physical union of two or more substances which are called components, these can be elements or compounds, whose particles do not mix uniformly. The components of the mixtures have different properties, such as the state of aggregation, the density or the solubility. These properties allow substances to be identified and facilitate the separation of the components of a mixture, that is, through physical or mechanical processes we can isolate and obtain the components that make up the mechanical mixtures.

For what cellular function does the breathing rate help regulate?

Answers

Answer: The respiratory system works with the circulatory system to provide this oxygen and to remove the waste products of metabolism. It also helps to regulate pH of the blood. Respiration is the sequence of events that results in the exchange of oxygen and carbon dioxide between the atmosphere and the body cells. The main purpose of respiration is to provide oxygen to the cells at a rate adequate to satisfy their metabolic needs. This involves transport of oxygen from the lung to the tissues by means of the circulation of blood. brainliest?
