Answer:
Greenhouse effect
Explanation:
Carbon-dioxide, methane and water vapor are green house gases, these gases absorb a large proportion of sunlight been reflected by the surface of the Earth. These absorption of sunlight leads to gradual increase in the annual temperature of the Earth. This phenomenon is known as greenhouse effect.
Answer:
Mitosis and meiosis are similar at the level of writing, and possess a very close mechanism; however, they do not achieve the same result!
Mitosis corresponds to a single "asexual" cell division of somatic cells (almost all cells in the body), and clones two daughter cells from a mother cell, which will be identical, and inherit exactly the same heritage genetic, indeed these two daughter cells will each have an identical karyotype (same chromosomes) and an identical genotype (same alleles) to that of the mother cell.
Meiosis corresponds to two successive "sexual" cell divisions affecting only germ cells; starting from a diploid cell (chromosomes present in pairs), meiosis leads to the formation of four gametes (haploid sexual cells, spermatozoa or oocytes) (a single copy of the chromosomes). Then, during fertilization, two gametes (each from meiosis, in the male and female) come together to form a zygote, in which diploidy will be restored.
The right answers are:
create two identical cells ==> mitosis
create four non-identical cells ==> meiosis
create haploid cells ==> meiosis
creates diploid cells ==> mitosis
occurs in all cels other tha gametes ==> mitosis
occurs in all cells related to sexual reproduction ==> meiosis

Explanation:
Answer:
True.
Explanation:
Red blood cells or erythrocytes carry oxygen to the cells of the body so that they can have energy and function properly. This is not the only function of red blood cells. Also, they carry dioxide, which is a waste product that needs to be out of our body. Erythrocytes carry the dioxide to the lungs, specifically to the alveoli. In the alveoli due to the inhalation, oxygen enters our body traveling up to the lungs, specifically to the alveoli, where thanks to the thin wall of it as well as the one on the capillaries that are in contact with it, the dioxide enters the lungs to be expelled in the exhalation, and the oxygen is taken by the red blood cells to be used in the cellular respiration and generate energy to keep the vital functions of our body.
The answer will be B. It is common sense
Vitamin A because of the nutrient value per serving is 40% (the highest).
