All of the white-tail deer living in an ecosystem are considered as a population. Thus, the correct option is C.
A population is the complete set group of individuals, a nation or a group of people with some common characteristics. A population is the pool of individuals from which a statistical sample can be drawn for a study.
A population consist of individuals which can interbreed with each other and produce fertile offspring. Thus, can maintain their number in an ecosystem such as all the white-tail deer organisms living in an ecosystem make a population. Many different population form a community.
The characteristics of a population include population density, natality, mortality, population growth, age distribution, and population fluctuations.
Therefore, the correct option is C.

Nutrients from fertilizers, such as nitrogen and phosphorus, can be harmful to aquatic ecosystems primarily because they promote excessive growth of algae and aquatic plants. Hence option b "The increase in algae population reduces oxygen in the water" is correct.
This excessive growth is known as eutrophication. The process unfolds as follows:
Nutrient Input: Fertilizers with nitrogen and phosphorus are often utilized in residential and agricultural settings. These nutrients may be introduced into surrounding water bodies by runoff from these locations.
Algal Blooms: Nutrients function as fertilisers for algae and aquatic plants, causing algal blooms. Algal blooms are therefore created as a result of the fast growth in the population of algae. These blooms can completely cover the water's surface, turning it green or murky.
Oxygen Depletion: The process of decomposition consumes oxygen when the algae and aquatic plants die and degrade. An higher need for oxygen results from the large amount of organic material from the deceased organisms. As a result, the amount of dissolved oxygen in the water may decrease.

Answer:
It is involved in the process of conjugation-exchange of genetic material between two bacteria
Explanation:
Conjugation is one of the ways by which bacteria exchange their genetic material (horizontal gene transfer). Two bacterial cells must physically connect in order to perform the conjugation. The linking occurs through a pilus.
Pilus is an appendage on the surface of bacteria cell and it is also called fimbria. Pilus is filamentous, tubular and composed of oligomeric proteins-pilin.
Donor cell contain pilus that will attach to the recipient bacterial cell and induce the transfer.
Answer:
This hierarchy comprises eons, eras, periods, epochs, and ages from the largest to the smallest
Explanation:
This hierarchy comprises eons, eras, periods, epochs, and ages from the largest to the smallest. All of these are shown in the geological time scale page.
Eon Era Period Epoch Age
Phanerozoic Cenozoic Paleogene Oligocene Chattian Rupelian
The Phanerozoic Eon reflects the period that most macroscopic species — bacteria, fungi, plants, and animals — lived through.
______ describes the average conditions of our atmosphere over a long period
of time.
Answer:
The answer is Climate.
Answer: JUST A COUPLE OF OIL DROPS
Explanation:
If we´re assuming that you´re talking about homemade popcorn, the trick is simple: 2- 5 drops of oil (depending on how much corn you want to pop).
Another secret that I´ve acquired wiht several failures, is that you count 15 seconds after the last popping and if you don´t hear another popping, then your popcorn are ready! (I know, it sounds redundant).
b. increased populations of fish
c. decreased levels of carbonate
d. all of the above
