Answer: States of matter; increases
Several factors influence the rate of diffusion and among these factors are temperature, STATES OF MATTER, electrical currents, and molecular size. For example, as temperature INCREASES, the rate of diffusion increases.
Explanation:
Factors influencing the rate of diffusion include:
- Temperature: High temperature increases the speed at which molecules move. Thus, as temperature increases, the rate of diffusion increases
- States of matter: Diffusion varies within the three states of matter. The diffusion of gases is much faster than that of liquids and solids, because the gas molecules are freer and therefore faster than the rest.
- Molecular size: The smaller the molecules, the faster the rate of diffusion while the larger the molecules, the slower the rate of diffusion.
Other factors include electrical currents.
Food Chains: Food chain is a model that shows flow of energy and nutrients from one organism to another organism in an ecosystem. ... A food also shows the relation between organisms as who they are related with each other by the food they eat. Plants and animals requires some type of food for survival.
The two system that is being described above is the nervous
system and endocrine system for they are the ones who are responsible in
providing the body long distance coordination with the use of homeostasis and
their role of maintaining it, in order to play their roles in the body.
Answer:
The correct answer would be Y-chromosome analysis.
Y-chromosome analysis is technique used to search the parental line of a boy on his father's side.
Gender of a person is determined by 
chromosome in humans. XX is present in females and XY is present in males.
Mother always passes X chromosome to her progeny but father passes both X and Y chromosomes. If X is passed from the father then the offspring will be a girl and if Y is passed from the father then the offspring will be the son.
The sons (F₂) of this son (F₁) will also bear the same Y chromosome as that of grand father (P).
Thus, Y chromosome always passes from father to son and hence, Y-chromosome analysis can help in identification of father of this young boy.
