All cells have a cell membrane. its basically what protects the cells from getting toxins that are sometimes entering your body. without a membrane on all cells, you would get sick a lot!!
Gametes are the cells in human body used for reproduction, such as sperms or eggs, and somatic cells are the other body cells, such as muscle cells, skin cells and all other.
First, they have different number of chromosomes. Gametes have only one set of chromosomes, while somatic cells have a complete 2 set of chromosomes. This is because fertilization requires 2 gametes joining together and this will help maintain the correct amount of chromosomes at last.
Second difference between them is that gametes are products of meiosis, while somatic cells are products from mitosis. Both are types of cell divisions but meiosis produces 4 genetically different cells while mitosis produces 2 genetically indentical daughter cells.
The statement above is TRUE.
The electrochemical gradient in the chloroplast is a gradient of electrochemical potential of ions which move across the membrane of the chloroplast during the photosynthesis process. The proton gradient across the thylakoid membrane drives the ATP synthesis during photosynthesis.
Friction always opposes motion.
<span>Whether it be through air resistance, or simple surface friction, the speed of a moving body always decreases when some frictional force acts on it. For objects sliding on a surface, friction is less than for objects at rest on the same surface

Answer: c.composition, temperature, and function.
Atmosphere can be classified into composition, temperature, and function. The composition has two region, heterosphere and homosphere. The temperature will be divided into thermosphere, mesosphere
, stratosphere, troposphere
. The function will be divided into ozonosphere and ionosphere
