<span>The control group is as similar as possible to the experimental group except that it is not exposed to the independent variable. The independent variable is the variable the researchers manipulate to determine its effect on the dependent variable. The dependent variable is not changed. The other group is exposed to the independent variable.</span>
Answer:
chlorophyll
Explanation:
Most plants contain a special colored chemical or pigment called chlorophyll that is used in photosynthesis. Chlorophyll is what absorbs the sun's energy and turns it into chemical energy. Not all the light energy from the sun is absorbed. Sunlight has many different colors in it.
Answer:
For cells in the body that replicate, they undergo mitosis to produce two identical daughter cells from one stem cell. These cells are going through a cycle, called the cell cycle, with several stages leading to the formation of daughter cells. The longest stage, and the one in which most cells are found, is called interface
Answer: Wind Turbines
Explanation:
A wind turbine is a device which is used to transform the kinetic energy from wind into electrical energy. It is useful in generating electrical energy from an alternative renewable source of energy that is wind. It is affected by the speed of the air currents.
A wind turbine efficiency is affected by the air column and the sea surface but it is not affected by the water column or the seafloor.
<span>Crossover is the first way that genes are shuffled to give rise to genetic diversity. Crossover takes place in sexual reproduction. Chromosomes line up side by side and break off pieces of themselves, then trade those pieces with each other. When they break at the same place (locus) in the sequence of base pairs, the result is an exchange of genes called genetic recombination. That is the normal way for crossover to occur. Genetic recombination ensures that the daughter cells produced have a different genetic makeup from the parent cell and thus diversity is created.</span>
