Which do solar flares and coronal mass ejections have in common? Select the two correct responses.
A. They appear as dark spots on the sun's surface.
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.
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.

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.

Which of the following energy transformations occur when humans use energy from food to exercise?
A. Mechanical - thermal - chemical
B. Thermal - electrical - mechanical C.Radiant - mechanical - thermal
D. Chemical - mechanical - thermal
Answer:
D. Chemical - mechanical - thermal
Explanation:
Food contains chemical energy; when our bodies break down and digest food, the bonds that are broken apart release chemical energy. Our bodies convert this to mechanical energy to power movement, from movements as small as blinking or our hearts beating, to bigger movements like running or swimming. When we exercise or move, we also release heat which is thermal energy.
The energy transformations that occur when humans use energy from food to exercise is: D. Chemical - mechanical - thermal.
What is energy?Energy can be defined as the ability to do work. Thus, energy must be possessed or transferred to a physical object (body) before it can be used in doing a work or heating a system.
The forms of energy.In Science, there are different forms of energy and these are;

So according to the scientific explanation of how food from plants provides energy for body processes.
Through the system of mobile respiration, the electricity in meals is modified into electricity that may be utilized by the frame's cells. Initially, the sugars withinside the meals you consume are digested into the easy sugar glucose, a monosaccharide.
Recall that glucose is the sugar produced through the plant for the duration of photosynthesis. The important feature of easy carbohydrates is to offer the frame electricity.
An example is a goat and plant food chain.
What is food energy?Food energy is chemical electricity that animals (such as humans) derive from their meals to maintain their metabolism, such as their muscular activity. Most animals derive maximum in their electricity from cardio respiration, specifically combining the carbohydrates, fats, and proteins with oxygen from air or dissolved in water.
