Answer:
A) The main functions of mitosis are growth and repair. Some cells once fully formed do not undergo cell division, such as nerve cells and muscle cells. Since you can never re-grow or repair these types of cells once they are mature, you must take care of the ones you have.
b)The experiment will lack a purpose.
c)The experiment will not be repeatable.
d)The experiment will not have variables.
Answer;
The experiment would lack a control group
Explanation;
-An experiment deliberately imposes a treatment on a group of objects or subjects in the interest of observing the response.
-Experimental design involves taking time and effort to organize the experiment properly to ensure that the right type of data, and enough of it, is available to answer the questions of interest as clearly and efficiently as possible.
-A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable. This increases the reliability of the results, often through a comparison between control measurements and the other measurements.
B. The distribution of sunlight.
C. The oceans' currents.
D. The prevailing winds.
The Earth has three main climate zones because of the differences in latitude and the distribution of sunlight.
Climate is the average weather conditions in an area for over a long period. Three major climate zones on Earth are:
1. Polar zone
The characteristic of this polar climate is cool summer and long extremely cold winter. The polar climate has a freezing climate and most of the time below zero degrees. The farther north of Canada, Europe, and Russia are the area that categorizes in this polar zone.
2. Temperate zone
The temperate climate zone lying between 23.5 degrees and 66.5 degrees north and south latitudes. Temperate climate zones experience warm to hot summers and cool winters, with the greatest temperature variations throughout the year.
3. Tropical zone
The regions between the equator and the tropics are tropical zone. In this zone, the temperature is warm, has the most rain and little temperature variation. The climate is hotter here because the Sun’s light is directly overhead at the equator. An area in this zone has lush plants and trees and varied animals.

The cell membrane is composed of a phospholipid bilayer.
The cell membrane is primarily composed of a mix of proteins and phospholipids
Phospholipids are a major component of cell membranes. They a head and a tail. The head is hydrophilic (attracted to water) and the tail is hydrophobic (repelled by water).
They form a bilayer in which their hydrophilic heads face the aqueous cytosol and extracellular fluid while their hydrophobic tails face away from the cytosol and extracellular fluid.
The lipid bilayer is semi - permeable
b. variables.
c. hypotheses.
d. quantitative data
Answer:
The correct answer would be d. quantitative data.
Quantitative variables refer to the measures of values which can be expressed as numbers.
These include numeric variables such as how much, how many, how often et cetera.
For example, the growth of a plant, that is, a measure of its height over two weeks period.
