Answer:
Types of variation in genetics
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring)
other answer
There are three sources of genetic variation: mutation, gene flow, and sexual reproduction. A mutation is simply a change in the DNA. Mutations themselves are not very common and are usually harmful to a population. Because of this, mutations are usually selected against through evolutionary processes
gravity
B.
temperature
C.
air pressure
D.
clouds
You have to choose 2.
if you want to know what describes weather, you have to think about it and eliminate the one that are obviously not correct.
So, gravity is obviously wrong.
Temperature is definatly one because you need temperature to calculate how cold/hot it is. Air pressure and clouds are the ones im not sure about. Clouds dont really describe weather but they could if you say cloudy. I think air pressure is needed to find out how strong the wind is but im not sure
Hope I helped a bit

Answer: The correct answer for the fill in the blank is A) Circulatory, immune.
Circulatory system also called cardiovascular system is a vast network of organs and vessels that allow the circulation of blood so as to transport nutrients, oxygen, other gases, and hormones to different parts of the body.
Blood contains different cells like white blood cells, red blood cells, platelets.
White blood cells ( also called leukocytes) work closely with immune system. They provide defense against pathogen ( disease causing organisms) through various ways ( like ingesting foreign material, producing antibodies to clear the antigens). By doing so, they protect us from infection and disease.
