D. a species that has become too populous and threatens the survival other of species
Answer: I believe it's C
Explanation: edg 2021
The correct option is C.
Why do they call it a right whale?
The right whale got its name because it was the right whale to hunt—it moved slowly and would float after being killed. A North Atlantic right whale mother and calf were spotted off the U.S. southern coast by NOAA researchers during the 2020 breeding season.
How rare is a right whale?North Atlantic right whales have been listed as endangered under the Endangered Species Act since 1970. The latest preliminary estimate suggests there are fewer than 350 remainings, with fewer than 100 breeding females. The number of new calves born in recent years has been below average.

Which type of resources form much more slowly than we use them? A: reusable B: renewable C: nonreusable D: nonrenewable
The type of resources from much more slowly than we use them is non-renewable resource. The correct option is D.
What are nonrenewable resources?A non-renewable resource is a natural resource that cannot be replaced quickly enough by natural means to keep up with consumption.
Carbon-based fossil fuels are one example. With the help of heat and pressure, the original organic matter is converted into a fuel such as oil or gas.
Nonrenewable energy sources are not only affecting our planet's atmosphere by increasing greenhouse gas emissions.
Coal and oil combustion emits particles that can pollute the air, water, and land. Some of these particles are captured and stored, but many are released into the atmosphere.
The use of fossil fuels also disrupts Earth's "carbon budget," which balances carbon in the ocean, earth, and atmosphere.
Thus, the correct option is D.

Place each land feature in the correct category based on the process that causes its formation
•Oxbow lake. Eroison by rivers
•Alluvial fan
•Delta
•Meander. Deposition by rivers
•Waterfall
•Flood plain
Deposition by rivers generates alluvial fans and deltas. Moreover, erosion by rivers generates waterfalls, flood plains, oxbow lakes and meanders.
An oxbow lake is a lake located in a meandering channel, and therefore on a floodplain.
Alluvial fans are accumulations of sediments created as flowing water bodies interact with mountains or hills.
A delta is a formation of land composed of sediments located in the mouth of the river.
A waterfall is a point in a river where water spills suddenly downward.

A drug that affects both divisions of the autonomic system is going to bind to, or block the nicotinic neurotransmitter receptor
A chemical that the body produces to interact with those receptors is called an endogenous chemical, whereas a chemical introduced to the system from outside is an exogenous chemical.
Nicotine is not a drug that is used therapeutically, except for smoking cessation. When it is introduced into the body via products, it has broad effects on the autonomic system.

How would a biomagnification “pyramid compare with an energy pyramid?
Answer:
Energy pyramid depicts flow of energy in the ecosystem: source of all energy in ecosystem is the SUN. Producers are only organisms in ecosystem who can trap the solar enrgy. So base of energy pyramid is always wide. A biomass pyramid shows the total dry mass of all living organisms at each trophic level.
Explanation:
Because the amount of the pollutant increases as it goes up the food chain, the biomagnification pyramid is inverted whereas the energy pyramid is consistently upright.
What is biomagnification?Biomagnification is the amassing of a chemical by an organism as a result of exposure to both food and water, resulting in a concentration that is higher than what would have been expected from equilibrium and higher than what would have occurred with only water exposure.
When dangerous chemicals like DDT that remain in the environment are indirectly absorbed by living things through food, this process is known as biomagnification.
When a higher-order organism consumes a lower-order organism that contains such compounds, the chemicals may accumulate in the higher-order organism.
The biomagnification pyramid is upside down because the amount of the pollutant increases as it moves up the food chain. The energy pyramid, however, is always upright.
Thus, this can be the comparison between the energy pyramid and biomagnification.

Which of the following statements best explains how the redox component of this reaction contributes to the reaction's ability to be reversible under cellular conditions?
A. FAD has no reduction potential when it is enzyme-bound.
B. FAD can be reduced by the sequential addition of one hydrogen at a time.
C. FAD/FADH2 is covalently bound to succinate dehydrogenase.
D. The change in the biochemical standard reduction potential is small.
The statement which best explains how the redox component of this reaction contributes to the reaction's ability to be reversible under cellular conditions is; Choice D: The change in the biochemical standard reduction potential is small.
Discussion:
A reversible process is one in which the system and environment can be restored to exactly the same initial states that they were in prior to when the process occurred, if we go backward along the path of the process.
However, the necessary condition for a reversible process is therefore the quasi-static requirement.The quasi-static requirement in this case is that the change in the biochemical standard reduction potential is small.Read more:
