A molecule that is important for cell functioning cannot diffuse through the plasma membrane, but needs a protein that can open and close to allow the molecule to diffuse. What is this protein called?

Answer:

A cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm. Within the cytoplasm lie intricate arrangements of fine fibers and hundreds or even thousands of miniscule but distinct structures called organelles.

Explanation:

Only 10% of calories will be transfered to the next higher level.

5000 * 0.1 = 500.

500 calories will transfer to the secondary consumers.

The number of calories that will be transferred to secondary consumers will be-

10% of 5000 = 500 and

10% of 500 =50 calories.

The ten percent law explains the energy transfer among the trophic levels in a food chain. It was given by Raymond Lindemann.

According to this law, when the energy is transferred from one trophic level to the next, ninety percent of the energy is lost in the form of heat and only ten percent of the energy is received by the next trophic level.

For example, if an energy level or a trophic level has 10,000 calories, only ten percent will be received by the next energy level which is 1000 calories.

In an ecosystem, energy is produced by primary producers. If the primary producers start with 5000 calories of energy, the energy received by the next trophic level, i.e by the primary consumers will be ten percent of 5000. This will be equal to 500.

Therefore the energy received by secondary consumers will be ten percent of 500, which will be equal to 50 calories.

Explanation:

1. Collection (a big body of water or an area in which water is gathered)

2. Evaporation, the sun causes the water to vaporize into a gas

3. Condensation, the cold temperatures in our atmosphere changes the gas into a liquid or solid ice

4. Precipitation, when the ice (or water) droplets get too heavy, they fall and create rain or other precipitation like snow, hail, sleet, etc.

5. Runoff, water on the ground runs off to gather into a big body of water.

And then the cycle repeats.

Answer:

i think it might be carbon dioxide, but sorry if i'm wrong

Explanation:

Answer:

It's Glucose ([tex]C_{6}H_{12}O_{6}[/tex])

Explanation:

This is how you should remember it. Synthesis in photosynthesis mean to make and usually plants are the ones using photosynthesis, and what do plants eat? They eat sugar that they made by using Carbon Dioxide and water, and the sugar's name is glucose. Anything that ends with -ose means it's a name of a type of sugar.

Chlorophyll is the green pigment inside the chloroplasts. They help the plant convert the energy taken into glucose. More specifically they absorb light which is the energy that converts the carbon and the water into glucose.

Answer:

Well, you will need to see how this fungus looks like. I would say it is a green, black, and brown color and it would be classified as an mold type fungus.

oo, The Big Bang theory predicts how much of each element should have been made in the early universe, and what we see in very distant galaxies and old stars is just right. You cannot look in new stars, like the Sun, for this evidence, because they contain elements that were created in previous generations of stars.

Explanation:

Angiosperms are categorized into three different forms. Seen attributes such as color, leaf form, or fruit size are used by the artificial classification scheme to group plants. The natural classification scheme uses more scientific means to classify plants, such as chemistry, morphology and desired growth locations.

3 general ways that angiosperms may differ from one another-

Angiosperms are flowering plants, which are characterized by the production of reproductive structures called flowers. There are three ways to categorize angiosperm on the basis of difference.

On the basis of seed coats or leaves, these can be either monocot or dicot. The other difference is that they have soft stems or woody stems. The third major difference is if these are annuals or perennials.

Answer:

C) Iron and oxygen combine to form iron oxide

Explanation:

Iron react with oxygen to form iron oxide in the rusting of iron nails.

The nails of iron is made up of iron that is unstable which reacts with oxygen that is present in the air that lead to rusting of iron nails. This reaction can be prevented by painting the metal that covers the surface and prevent the reaction of iron and oxygen which results in the long life of iron materials. The rusting of iron deteriorates the metals which causes in the reduction in the life of iron materials so we can conclude that iron reacts with oxygen results in the rusting of iron nails.
