4. Divergent evolution: A pattern of evolution in which very different species evolve from one common ancestor.

5. Gradualism:  A theory of evolution that states that a species evolves by consistent, small, steps.

Why is the ability of the cell membrane to be "picky" important?
Yuliya22 [10]

Answer:

Hi there!

Your answer is:

It is very important for the cell membrane to be <em>semi-permeable</em> because the ability to pick and choose what comes in and out of the cell keeps the cell safe! The membrane can choose to block out nasty germs and can also choose to get rid of internal waste.

An example of when this is important is in this scenario:

Let's say the cells are in a really salty solution. Naturally, salt will want to pull the water out of the cell. If the membrane <u>wasn't</u><u> </u> semi permeable, the water would listen to the salt and leave the cell. This would cause cell death. <u>BECAU</u><u>SE</u> the membrane is semi permeable, they can choose <em>not</em> to give the salt any water, keeping them alive

Hope this helps

Why do we want to turn genes off or on?
Dmitrij [34]

The process of turning off and on of genes is known as gene regulation.

Explanation:

When the gene is turned on, it instructs the cells to construct a particular protein. The proteins are the molecules that build your body with collagen, tendons, and bones or keratin in your hair.

The gene regulatory proteins allow the individual genes of an organism to be turned on or off . in different cell types there are different selections of gene regulatory proteins. The patterns of the gene expression gives each cell its unique characteristics.

Each cell produces or turns on only a fraction of its genes. the remaining genes are repressed or turned off. this process is known as gene regulation. The signals from the environment or from other cells activate proteins called transcription factors.

How does the feild that surrounds the electromagnet differ from the Earths magnetic field
tino4ka555 [31]

The differences between the geomagnetism and electromagnetism are given below.

<h3><u>Explanation</u>:</h3>

Geomagnetism is defined as the magnetic field that is located all around the earth. Whereas electromagnetism is defined as the magnetic field that is produced due to passing of electricity through a conductor.

The geomagnetism is formed because of the molten elements of iron etc which are present inside Earth's core, and are continuously moving. It mostly resembles the solid block magnet in its field characteristics. But electromagnetism is different. It can be changed according to the current input which isn't possible for Earth’s magnetic field.
