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

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.
Construct a cladogram using the multiple alignment of a protein sequence found below.

Distinguish between Diet and Nutrition
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.#CarryOnLearning

Most diving birds have (relatively) long necks and shorts legs, although their necks aren't as long as say herons, storks or egrets. Take the common loon for instance. Their necks can be up to half as long as their bodies but their legs are so short and set so far back that they are very awkward on land.

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.
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 lungGaseous 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.

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
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.

For what cellular function does the breathing rate help regulate?
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?

Why is it important for soil to contain nitrogen, phosphorus, magnesium, and potassium??
Answer:
Soil is one of the main sources of nutrients needed by plants in order for them to grow. Nitrogen is used by plants for lots of leaf growth and good green color. Phosphorous is used by plants to help form new roots, make seeds, fruit and flowers. Potassium helps plants make strong stems and keep growing fast. It's also used to help fight disease. Magnesium is the central core of the chlorophyll molecule in plant tissue.
Explanation:
Hope this helped a little bit.
Answer:
Explanation:
1.Without enough nitrogen in the soil the plant cannot grow taller, or produce enough food.
2.phosphorus results in higher grain production, improved crop quality, greater stalk strength, increased root growth, and earlier crop maturity. That is important because crops take up phosphorus only from the soil solution.
3.The role of Magnesium in the soil is the central core of the chlorophyll molecule in plant tissue. Thus, if Mg is deficient, the shortage of chlorophyll results in poor and stunted plant growth. Magnesium also helps to activate specific enzyme systems.
4. Potassium is a critical nutrient that plants absorb from the soil, and from fertilizer. It increases disease resistance, helps stalks to grow upright and sturdy, improves drought tolerance and helps plants get through the winter. Potassium triggers activation of enzymes and is essential for production of (ATP).Both uptake of water through plant roots and its loss through the stomata are affected by potassium.
