2)DNA is pivotal to our growth, reproduction, and health. It contains the instructions necessary for your cells to produce proteins that affect many different processes and functions in your body.

3)DNA is found inside a special area of the cell called the nucleus

Explanation:

Have a great day!

Answer:

1) It is a chemical in which genes are made up of. It is the chemical that is the basis of inheritance in nearly all organisms.

2) The DNA is very important as it contains the information required for protein production.

3) DNA is found in the nucleus of the cell.

Explanation:

The circulatory system is your heart and blood vessels, and it’s essential to keeping your body functioning. This finely tuned system carries oxygen, nutrients, electrolytes, and hormones throughout your body. Interruptions, blockage, or diseases that affect how your heart or blood vessels pump blood can cause complications such as heart disease or stroke.

These complications can arise due to a variety of factors, from genetics to lifestyle. Read on to learn more about the types circulatory system diseases and disorders and what their symptoms are.

Answer:

Infrared images also show thermal, or heat, radiation. While a visible-light image from this vantage point would simply show the face of the planet as dimly lit by sunlight reflected off the rings, Saturn glows brightly in this view because of heat from Saturn's interior.

In a second version of the image, scientists "stretched" or exaggerated the contrast of the data, which brings out subtleties not initially visible.

When these small particles are lit from behind, they show up like fog in the headlights of an oncoming vehicle.

• The C ring also appears relatively bright here; not because it is made of dust, but because the material in it -- mostly dirty water ice -- is translucent. In fact, in the 18th and 19th centuries, it was known as the "crepe ring" because of its supposed similarity to crepe paper.

• The wide, middle ring known as the B ring -- one of the easiest to see from Earth through telescopes because it is densely packed with chunks of bright water ice -- looks dark in these images because it is so thick that it blocks almost all of the sunlight shining behind it.

Answer:

blood

Explanation:

beacause it distrubites materials throoutght your body

Answer:

C is the answer

Explanation:

Answer:

50

Explanation:

Answer:

A great example is the peppered moths evolution. Since the Industrial Revolution the birch trees started to turn black from the soot. This casued all the white moths to be eaten from birds. The ones that were left to mate were black moths which favored the black gene. So overtime black moths became more common. They were naturaly selected based on color to survived and pass down their black colored genes.  

Explanation:

A population of moths might evolve if only a few members can blend in with their environment, and those who cannot blend in would be chosen by the predator. Through natural selection, the blended population will grow.

Natural selection is the force that selects the organism in the ecosystem that can fit best in the environment. In the case of the peppered moth, the light-colored moth was earlier camouflaged with the light color of the bark, so the dark moths were chosen by the predator. Later, after industrialization, the bark became black from pollution, allowing light moths to be seen and eaten by the predator, demonstrating how natural selection varies depending on environmental conditions.

Hence, the population of moths might evolve if only a few members can blend in with their environment, and those who cannot blend in would be chosen by the predator. Through natural selection, the blended population will grow.

Explanation:

Answer:

Its wavelength decreases

Explanation:

There is an inverse relationship between distance and light intensity - as the distance increases, light intensity decreases. This is because as the distance away from a light source increases, photons of light become spread over a wider area.

Answer:

"Fat cell, yellow bone marrow, femur, nervous system."

Explanation:

Via process of elimination, we can eliminate the first and last answers, as the biggest unit of a single organ system would be the entirety of the system, and those have the system itself jumbled in between the list.

That leaves us with the center-two answers. I believe "bone" is too vague, meaning that bone, in some cases, may be smaller than cartilage, thus, leaving you with the above answer.

Answer:

Water evaporates and ends up in clouds high up in the atmosphere. Since it is colder in the upper atmosphere, the clouds condense.

Answer:

Condensation generally occurs in the atmosphere when warm air rises, cools and looses its capacity to hold water vapor. As a result, excess water vapor condenses to form cloud droplets.
