Two populations of frog species are separated by a group of mountains. A tunnel is built through the mountains, through which some of the frogs are able to safely navigate, and attempt mating with frogs on the other side of the tunnel. However, their heroic feat is for nothing, because their offspring all produce sterile young. This scenario is an example of
Answers
Answer:
Post reproductive isolation → Hybrid sterility
Explanation:
The biological concept of species states that individuals of a species can not mate and reproduce with individuals of another species. But if they get to reproduce, the progeny will not be viable or fertile. There will not be any reproductive success.
There are different reproductive isolation mechanisms, which are barriers that inhibit or interrupt the genetic flow between different species.
Reproductive barriers are isolation mechanisms that prevent mating between two or more species. The prezygotic mechanism avoids fertilization between individuals of different species, while the postzygotic mechanism impedes the zygote to develop and reach the adult stage.
Postzygotic mechanisms or barriers include
Hybrid inviability, Hybrid sterility, Hybrid decreased viability or fertility, Cytoplasmic interactions.In the exposed example, it seems that the mountains separating the frogs´ populations made a place for the development of postzygotic barriers, specifically hybrid sterility. Frogs from one population get to mate and produce offspring with the frogs of the other population, but their progeny is sterile.

Earth's population over the centuries has risen at an increasing rate. So, the correct option is C.
How the population of Earth is increasing?This sharp increase in population has been primarily caused by an increase in the proportion of individuals reaching breeding age, the gradual extension of human life expectancy, growing urbanization, and quickening migration. This expansion has been accompanied by significant changes in the fertility rate.
One of the key reasons for India's population expansion is a drop in death rates brought on by better medical services and a steady birth rate. The widespread illiteracy in India makes people believe that "children are god's blessings," which makes them opposed to the idea of "family planning."

Answers
Answer:
a. amount of a pesticide that can be applied to a food and how much of the pesticide that is permitted to remain on the food in the marketplace.
Explanation:
Pesticides are chemical substances used to get rid of or kill pests that attack crops on farmlands. These pesticides, although help the farmer to get rid of his pest problem and likely have an increase in yield, are dangerous to human and animal health if consumed.
As set up by the Environmental Protection Agency (EPA), pesticide tolerance is the amount or quantity of pesticide chemical that can be applied to a food and how much of the pesticide that is permitted to remain on the food in the marketplace.
Give the functions of the following parts of the respiratory system - Nostril - trachea - bronchiole - alveoli - pharynx - larynx - lungs - ribs - diaphragm
Answers
Answer:
Respiratory System: The respiratory system's main job is to move fresh air into your body while removing waste gases.
Nostril: To warm air on inhalation and remove moisture on exhalation.
trachea: Serves as passage for air, moistens and warms it while it passes into the lungs, and protects the respiratory surface from an accumulation of foreign particles.
bronchiole: To deliver air to a diffuse network of around 300 million alveoli in the lungs.
alveoli: To exchange oxygen and carbon dioxide molecules to and from the bloodstream during breathing.
pharynx: Helps the respiratory system by allowing air to make its way to the respiratory tract.
larynx: Produces vocal sounds and prevents the passage of food and other foreign particles into the lower respiratory tracts.
lungs: To help oxygen from the air we breathe enter the red cells in the blood.
ribs: To aid respiration and help protect the lungs.
diaphragm: Contracts and flattens when you inhale. Creates a vacuum effect that pulls air into the lungs, and relaxes when exhaling.

A common genetic mutation that lowers levels of the enzyme cathepsin C severely reduces a person’s ability to ward off periodontitis, or gum disease. The enzyme triggers immunological reactions that destroy diseased cells and eliminate infections
in the mouth. But researchers are developing ways to restore the enzyme to normal levels. Once that happens, we will be able to eliminate periodontitis.
Which one of the following is an assumption on which the argument depends?
(A) Restoring cathepsin C to normal levels is the only way to eliminate periodontitis.
(B) Genetic mutation is the only cause of lowered levels of cathepsin C.
(C) Researchers will soon succeed in finding means of restoring cathepsin C to normal levels.
(D) Persons who do not have the genetic mutation that lowers levels of cathepsin C do not get gum disease.
(E) A person whose cathepsin C level has been restored to normal will not suffer from periodontitis.
Answers
Answer:
(E) A person whose cathepsin C level has been restored to normal will not suffer from periodontitis.
Explanation:
Considering the fact that there may be some other causes of periodontitis aside from the lowered levels of the enzyme.
Therefore, should there be some other causes of periodontitis, hence, it can be concluded the process of restoring the enzyme to normal levels might not be sufficient for eliminating periodontitis.
Hence, the author's argument is solely based on this assumption, and option. Hence, option (E) is the correct answer.
