The correct answer is A. Sunspots

Explanation:

The Sun is the star that is the center of the Solar system where Earth is located and that is mainly composed of hydrogen, helium and other elements such as oxygen, carbon or iron. In terms of the photosphere or the outer shell of the Sun this is a plasma layer that is mainly observed as uniform in color, but also presents dark areas that are called sunspots, these are cooler areas in the surface of the sun that exist as a result of the magnetic field of the sun; additionally, this can appear individually or in groups which are called Sunspot Groups. Therefore, the dark, cooler areas on the sun's surface are called Sunspots.

What would happen if we didn't have photosynthesis and cellular respiration?
gayaneshka [121]
1)Without photosynthesis: If we didn't have plants, algae and bacteria  to do the photosynthesis, CO2, a air pollutant wouldn't be converted in to glucose for those organisms and there would be no more Oxygen released to the atmosphere. Less photosynthesis  means less oxygen production and many organisms, like us, would die.
2)Without cellular respiration: Without this process we couldn't convert our food into the energy, ATP, necessary for the cells to function properly. Plus, this process also forms water, and without it, it would be another reason for the death of the cells.
Ultimately, will cause the death of the aerobic organism.

Two nuclei now form, followed by cytokinesis. how many chromosomes are in each nucleus
tangare [24]

<span>It depends upon what type of cell which underwent the division. If it is a somatic cell and it underwent mitosis, the number of chromosomes remains unchanged at 46 in each cell. On the other hand, if it is a sex cell, the number of chromosomes is halved (23) after meiosis. By the way, mitosis is the term for cell division among somatic cells and meiosis is for the sex cells.</span>

If the mass of a material is 41 grams and the volume of the material is 15 cm^3, what would the density of the material be?
lukranit [14]

The answer would be

2.7 g/cm³

For those who need the complete solution to this, you can refer to my answer.

The formula for density is:

D = \dfrac{M}{V}

Where:

D = Density

M = Mass

V = Volume

The trick to problem solving is to fill in what you know and derive/solve for what you don't know.

Given in the problem:

M = 41 grams (g)

V = 15 cm³

So with that just fill in the formula:

D = \dfrac{M}{V}

D = \dfrac{41g}{15cm^{3}}

D = 2.733333... g/cm^{3}

Round it off and you get 2.7 g/cm³.
