Answer:

Explanation: Diffusion is a process that allows particles to move from areas of high concentration to areas of lower concentration. The process requires that particles are moving. As long as particles are not at a temperature of 0K (absolute zero) they have kinetic energy (energy of movement)

Answer:

The net force is the vector sum of all the forces that act upon an object. That is to say, the net force is the sum of all the forces, taking into account the fact that a force is a vector and two forces of equal magnitude and opposite direction will cancel each other out.

Answer:

Formula of Net Force

FN is the force acting on a body. When the body is at rest, the net force formula is given by, FNet = Fa + Fg.

Answer:

Explanation:

just A, I remember doing this in like 4th or 3rd grade don't really remember but I makes sense

Answer:

Order, Sensitivity and response to stimuli, Reproduction, Growth and developement, Regulation, Homeostasis. Hope that helps!

Reproduction is the process in making more of the same species. we won't get into that. Order is the food chain, and what the animal kingdom should cisist of. In sensitivity and response to stimuli,  organisms respond to diverse stimuli. For example, plants can bend toward a source of light, climb on fences and walls, or respond to touch. Regulation is kinda like the ability to adapt. Animals come from all over, so they need to adapt to the climate, resources, and other animals around.    

Answer: How might it be possible for you to show a trait when neither of your parents show the same trait. It can be carried to you when the chromosomes combine even if the parents don't possess the same trait  It can skip and be dominant for you so you would be able to see it in your genetic make up.

Explanation:

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?

Answer:

here is the answer key

Explanation:

Answer:

5.0 x 10-4 g/kg

Explanation:

This is because

I mrad is equivalent to 1/100,000j/kg

Therefore,

To convert 50 mrad to j/kg

= 50/100,000

= 5 × 10^-4j/kg.

Millirad is a decimal unit or rad which is the unit for measuring absorbed ionization radiation.

Answer:

Metamorphism is the answer

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.

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.

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.

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:

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 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.

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.
