Answer:
a = increased temperature increases the kinetic energy of the gas molecules.
b = higher temperatures will increase the energy and therefore the movement of the molecules, increasing the rate of diffusion.
Answer:
<u><em>The correct option is C) Meiosis produces 4 daughter cells each with half the number of chromosomes of the original cell.</em></u>
Explanation:
There are two main processes by which cell divides:
1) Mitosis
2) Meiosis
All the cells of the body divide by the process of mitosis except the sex cells.<em> Sex cells divide by the process of meiosis.</em>
Meiosis can e described as a type of cell division in which four daughter cells are formed each having half the number of chromosomes as the parent cell. This is because the cell has to attain half of the maternal and half of the paternal chromosomes at the time of fertilization.
Crossing over and independent assortment are the phenomenon of meiosis which bring genetic diversity among parent and children.
The phenotype is the physical appearance of an organism, while the Genotype is the genetic composition of an organism. Phenotype is observable and are the expression of the genes of an individual. So even the organism with the same species may differ, with a minute difference in their genotype. This is the main difference between the two.
We can notice one’s hair colour, eye colour, height, weight, skin colour, etc. but cannot look at genes responsible for these characters, so the observable physical look is the phenotype while the unnoticed genes responsible for such characters present in the DNA of cell of the individual is genotype.
To explain the above lines, here is the simple example of a pure red colour flowering plant (RR) is crossed with the white colour flowering plant (rr). The result of the Genotype of the F1 generation will be – Rr (Hybrid red colour), and the Phenotype of the F1 generation will be the – Red colour flowering plant.
Genotype and phenotype are the two very closely related and similar-sounding words, but their meaning is different. Our earth has a dynamic variety of organisms, present in soil, water and on land. But as the genome of each organism is different, and so there phenotypes also whether it’s their colour, height, weight or other morphological features.
