Answer:

I think it's C, sorry if I'm wrong. I just took this class.

Answer:

C. help the cell interact with its external environment

Explanation:

A transmembrane protein (TP) is a type of integral membrane protein that spans the entirety of the cell membrane. Many transmembrane proteins function as gateways to permit the transport of specific substances across the membrane.

Although transmembrane proteins have different specific functions, they always HELP the cell interact with its external environment.

Transmembrane proteins are a broad category of membrane proteins that act as carriers and/or transporters in order to allow the movement of specific substances across cell membranes.

After binding to their specific ligands, the three-dimensional (3D) shape of transmembrane proteins changes in order to allow the movement of molecules and ions through the cell membrane.

For example, aquaporins are a type of transmembrane protein that regulates the entry of water (H2O) molecules into and out of cells.

In conclusion, although transmembrane proteins have different specific functions, they always HELP the cell interact with its external environment.

Answer:

a transform fault boundary, where both plates are oceanic

Explanation:

A volcano is formed when hot molten rock, ash and gases escape from an opening in the Earth's surface. The molten rock and ash solidify as they cool, forming the distinctive volcano shape shown here. As a volcano erupts, it spills lava that flows downslope.

Answer and Explanation:

Answer:

Fertilization would result in a zygote with twice as many chromosomes as the parents.

Explanation:

Meiosis creates four haploid cells from a diploid parent cell. These haploid cells are the sex cells - sperm cells and egg cells.

Since these cells are haploid (containing 23 chromosomes, half the amount of chromosomes as the parent diploid cells), when they fuse during fertilization, they form a diploid zygote containing 46 chromosomes.

Answer:

B) Fertilization would result in a zygote with half as many chromosomes as the parents.

Explanation:

Answer:

the conclusion should be... depending on the amount of fertilizer you use it will have more or fewer flowers on each plant due to a lot of fertilizer or less. hope this helps have a good day.

Answer:

18 m/s^2 A newton is defined as kg*m/s^2 and you want to accelerate a mass in kg, getting a result of m/s^2. So what you need to do is cancel out the kg unit in the newtons. You can do that by dividing the newtons by kg. So let's do the math. 10.8 kg*m/s^2 / 0.60 kg = 18 m/s^2 So the ball has an acceleration of 18 m/s^2. Remember, look at the units you have and the units you desire. By doing so, the math operations become obvious.

Answer:

B. Egg and sperm cells must only have the number of chromosomes so that when they combine the number will equal 46.

Explanation:

The purpose of meiosis is to shuffle genetic information and cut the cellular chromosome number in half, from 46 chromosomes to 23 chromosomes. In this way, when an egg and sperm cell combine during fertilization, the resulting embryo will inherit the appropriate amount of unique genetic information from each parent.

Explanation:

Answer/Explanation:

Because the journal is peer-reviewed, it means their report is assessed and critiqued by experts in the field. This means the data is more reliable and  more likely to be trusted by other scientists in the field.

Additionally, the journal is likely to be specialized and used to accepting scientific reports, meaning they will have certain regulations and criteria for publishing.

PLEASE GIVE ME AS BRAINLIEST

Answer:

D

Explanation: D. The process is cellular respiration which chemical energy from food sources is released in

the form of ATP.

Answer:

Oxygen and carbon dioxide move across cell membranes via simple diffusion, a process that requires no energy input and is driven by differences in concentration on either side of the cell membrane.

Explanation:

Simple diffusion is responsible for the spread of an air freshener through a room, or of a few drops of dye to eventually turn a glass of water a uniform color. Molecules naturally disperse from areas of higher concentration to lower concentration.

As oxygen-rich (and carbon dioxide-poor) blood travels by a cell the oxygen diffuses through the cell membrane to the area of lower concentration inside the cell. It can do this easily because the oxygen molecule (O2) is very small and has no charge or polarity. The oxygen is used up rapidly by mitochondria. This rapid consumption causes oxygen to constantly move into the cell from the blood.

The mitochondria creates carbon dioxide (CO2) as a waste product of cellular respiration (the process that makes energy for your body). Because the CO2 is of a higher concentration in the cell than in the blood passing by, this gas continually diffuses out of the cell. It too is small and uncharged so it can pass through cell membranes easily.

These movements require no energy (in the form of ATP) on behalf of the cell.

a technique that visualizes how specific

genes are used within a cell

Explanation:

Explanation:

Two oxygen atoms bonds with each other via covalent bonding.

In the formation of covalent bonds, two atoms with little to no electronegativity difference combines by sharing of the valence electrons. This why homonuclear molecules can be formed.

For the oxygen atom with 6 valence electrons;

   two electrons are shared by each atoms to make a complete octet and a stable molecule.
