Which part of the cell membrane does not mix with water?

Biology

It’s c the phosphate groups

So the phospholipids are arranged in a double layer (a bilayer) to keep the cell separate from its environment. Lipids do not mix with water (recall that oil is a lipid), so the phospholipid bilayer of the cell membrane acts as a barrier, keeping water out of the cell, and keeping the cytoplasm inside the cell.

When a horse and a donkey have an offspring, it is called a mule--a hybrid that cannot reproduce itself. Why are horses and donk
RUDIKE [14]

Answer:

Horses and donkeys are two different species but belong to the same family Equidae and the genus Equus. They both have different numbers of chromosomes.

Although they look quite similar in appearance, there are many dissimilarities.

The physical differences between horses and donkeys include:

Donkeys backs are flatter than horses.

Donkeys have smaller hoofs than horses.

Donkeys have longer and thicker ears than horses.

Horses tend to have a long face than Donkeys.

Horses have six vertebrates, while donkeys have only five.

Tails of horses and donkey differ. Horses have long tails, whereas donkey’s tail looks like a cow’s tail.

On the genetic level, the total number of chromosomes in the horse is 64 and donkey have 62 number of chromosomes. Mule is a hybrid of a female horse and a male donkey. Hinny is a hybrid of a female donkey and a male horse. Both the offspring (hybrid offspring) produced by donkeys and horses are infertile, sterile, cannot have its own offspring and both have 31 pairs of chromosomes each.

If the produced offspring is fertile then the animals are of the same species and if the produced offspring is sterile then they are of different species. Because of this, both horses and donkeys are considered as a separate species. A species is generally defined as a group of organisms, which are capable of interbreeding and creating viable offspring. In this case, mule and the hinny are not really a new species and are produced by two different species.

If you measure the rate of respiration of plant root hair cells, would you expect it to be the same as, more than, or less than
DaniilM [7]

Answer:

The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. In many ways, respiration is the opposite of photosynthesis. In the natural environment, plants produce their own food to survive.As with photosynthesis, plants get oxygen from the air through the stomata. Respiration takes place in the mitochondria of the cell in the presence of oxygen, which is called "aerobic respiration".

In plants, there are two types of respiration: dark respiration and photo respiration. The first kind occurs in the presence or absence of light, while the second occurs exclusively in the presence of light.<em>Plant respiration occurs 24 hours per day</em>, but <em>night respiration is more evident since the photosynthesis process ceases.</em> During the night, it is very important that the <em>temperature is cooler than during the day</em> because plants can experience stress. Imagine a runner in a marathon.

roots respire too!

One of the functions of the substrate is <em>to serve as a site for air exchange between the root zone and atmosphere</em>. In other words, <em>roots breathe oxygen like we do</em>. Different plants have different oxygen requirements for their root systems.

For example,

<em><u>the root system of a poinsettia requires a lot of oxygen, so it is best to use a substrate with high air porosity, while hostas can live well in a substrate with a high water holding capacity. </u></em>
