What is a cell?

The smallest unit of life is a cell. There are biomolecules in it. Every living thing is composed of several cell units. Different sorts of creatures contain various types of cells.

Prokaryotic cells are the most basic types of cells; they are only seen in unicellular organisms, do not engage in cell division, and lack real cell organelles and a nucleus, instead having DNA coiling up in the cytoplasm.

Eukaryotic cells are higher cells that contain cell organelles and have the capacity to carry out a variety of intricate tasks required by big organisms.

Thus, Cell signaling is a method of communication between or within cells, and a change in a cell's activity is conveyed as a signal that may set off a chain of events so that the body can respond appropriately.

B. They tend to occur during minimum points in the solar cycle.
C. They are caused by the sun's changing magnetic field.
D. They are explosive events that can affect Earth.

Answers

C. They are caused by the sun's changing magnetic field.

D. They are explosive events that can affect Earth.

Explanation:

I'm sorry if it is wrong but I am almost 100% that it is correct!

Have a good one!

The  solar flares and coronal mass ejections are caused by the sun's changing magnetic field. Also they are explosive events that can affect Earth. The correct options are C and D.

What is solar flare?

A solar flare is a massive explosion on the Sun caused by the sudden release of energy stored in 'twisted' magnetic fields.

However, not all solar flares are safe. While the Earth's magnetic field protects us from solar radiation, the sheer electromagnetic power of a flare disrupts power grids, internet connections, and other communication devices.

Ejections occur at varying rates depending on the phase of the solar cycle, ranging from about 0.2 per day near the solar minimum to 3.5 per day near the solar maximum.

Coronal Mass Ejections are large plasma and magnetic field expulsions from the Sun's corona.

The sun's changing magnetic field causes solar flares and coronal mass ejections. They are also explosive events that can have an impact on Earth.

Thus, the correct options are C and D as per the given scenario.
