Answer:
The sun gets its energy from the process of nuclear fusion. This process occurs in the sun's core or interior, where temperature and pressure are extremely high. During most of the sun's life, energy comes from the fusion of hydrogen nuclei
Explanation:
<u>Answer:</u>
<em>16 kinds of gametes can be expected from an individual with the genotype ppccttrr. </em>
<u>Explanation:</u>
<em>Gametes are the haploid mature germ cells which can be both male and female.</em> They have the ability to unite to opposite sex in the reproduction phase to form a zygote.
<em>The example of gamete is the sperm that is ready to fertilize the egg during reproduction. </em>so there will be 16 types of reproductive cell with single <em>set of unpaired chromosomes with the genotype ppccttrr.</em>
That is the cell membrane. Think of it as a gate around a city, that is how I remember it. The city is the cell, and the cell membrane is the gate that "protects" the city, and controls what can enter and exit.
Answer: B. Water molecules slow down until they begin to bond together.
Explanation: When water is cooled, energy is removed from the system, and the molecules begin to slow down. When the molecules have slowed suciently, their collisions are no longer energetic enough to overcome their electrostatic attraction, and they begin to bond together. The other answer choices are inaccurate. Since ice is less dense than water, high pressure compresses the ice and actually causes it to melt. (Compression has no effect on water volume.) Cooling has no effect on the shape of individual water molecules.
