Spreading out a wave over a larger area just causes the wave strength to weaken, but does not cause gaps to form. Therefore, if you look at photons as waves, spatial gaps never form in light as it travels through free space, no matter how dim it gets.
Answer:
Hormonal effects in newborns occur because in the womb, babies are exposed to many chemicals (hormones) that are in the mother's bloodstream. After birth, the infants are no longer exposed to these hormones
Explanation:
Answer:
The correct answer would be - 16 chromosomes or 8 chromosome pairs per cell.
Explanation:
In the body of an organism, all the somatic cells have the same number of chromosomes irrespective of their location in the body which is 2n or diploid. Liver cells would also have 2n number of chromosomes. The diploid number of cells are produced by the mitosis type of cell division or by fusing the sex cell that are egg cells and sperm cells. These sex cells are haploid of n number of cells or haploid.
If a sex cell as given in question sperm cells have 8 chromosomes then the liver cell would be 2n because sex cells after forming a zygote develooped to all other somatic cells including liver cells.
Sex cell = n = 8 chromosomes
liver cell - 2n = 2×8 = 16 chromosomes.
Respiration is the chemical reaction that break down nutrient molecules in living cells to release energy .
in humans and other living organisms except plants, our cells need energy ATP for muscle contraction and for cell division to repair damaged tissues and growth ,also for active transport which involves movement of molecules across a cell membrane against a concentration gradient.
la ósmosis, la difusión simple, la difusión facilitada y el transporte activo son mecanismos que permiten la entrada y salida de sustancias a través de la membrana celular
