An electron transport chain pumps protons across a membrane while transferring electrons from one chemical to another.
Answer:
Because offspring with two parents will share half of each parent's DNA.
Explanation:
Sex cells contain half of the genetic information of an organism's regular cells. This is because a sexually-produced organism will be unique; it will share genetic information with both of its parents, rather than be identical to its bearer (like an asexual organism would be). When a sex cell meets another sex cell, their DNA will meet as well and change/adapt to suit the organism. If a sex cell had all the information needed to create an embyro, instead of half, which requires another cell's information to fill the DNA void.... well, it would just do it.
Atoms are the smallest unit of matter. Atoms of isotopes of the same element contain the same number of protons.
<h3>What are isotopes?</h3>
Isotopes are atoms of the same element which have different numbers of neutrons but the number of protons and electrons remains same.
As the isotopes of the atom have the same number of protons, so, their atomic number will also be the same.
Thus, it can be concluded that atoms of isotopes of the same element contain the same number of protons.
