What types of materials are expelled from cells during exocytosis?
alex41 [277]

Large molecules such as hormones materials are expelled from cells during exocytosis

<u>Explanation:</u>

The materials inside the cells are transferred to the outside of the cell and this manner is termed as  Exocytosis. This method is termed as a kind of active transport since it needs energy for this transformation process. One of the major purposes of this process is to discharge trash matters like hormones and proteins.

For a cell to cell transmission and chemical signal messaging these methods are essential. Proteins that are newly generated are transferred to the peak of the plasma membrane by exocytosis. There are three general pathways of exocytosis.

Explain Mercury is the planet closest to the Sun. Why does it get so cold at night?
alexdok [17]

Answer/Explanation: On Mercury temperatures can get as hot as 430 degrees Celsius during the day and as cold as -180 degrees Celsius at night.

Mercury is the planet in our solar system that sits closest to the sun. The distance between Mercury and the sun ranges from 46 million kilometers to 69.8 million kilometers. The earth sits at a comfy 150 million kilometers. This is one reason why it gets so hot on Mercury during the day.

The other reason is that Mercury has a very thin and unstable atmosphere. At a size about a third of the earth and with a mass (what we on earth see as ‘weight’) that is 0.05 times as much as the earth, Mercury just doesn’t have the gravity to keep gases trapped around it, creating an atmosphere. Due to the high temperature, solar winds, and the low gravity (about a third of earth’s gravity), gases keep escaping the planet, quite literally just blowing away.

Atmospheres can trap heat, that’s why it can still be nice and warm at night here on earth.

Mercury’s atmosphere is too thin, unstable and close to the sun to make any notable difference in the temperature.

Space is cold. Space is very cold. So cold in fact, that it can almost reach absolute zero, the point where molecules stop moving (and they always move). In space, the coldest temperature you can get is 2.7 Kelvin, about -270 degrees Celsius.

Sunlight reflected from other planets and moons, gases that move through space, the very thin atmosphere and the surface of Mercury itself are the main reasons that temperatures on Mercury don’t get lower than about -180 °C at night.

One oak tree cell with 14 chromosomes undergoes meiosis. How many cells will result from this process,???
Tomtit [17]

Answer:

Four (4) cells

Explanation:

Meiosis is the type of cell division in which four daughter cells that are genetically different is produced. The daughter cells are gametes that have undergone a reduction in their chromosome number (by half).

For example, one cell of an oak tree with 14 chromosomes is said to undergo meiosis. This means that, based on the explanation of meiosis above, the oak cell will give rise to four (4) daughter cells containing 7 chromosomes each.
