The correct option is (c)New inorganic and organic substances are created from energy in the process that occurs in the cells of both self-feeders and other-feeders.
What are Autotrophs(self-feeders) and heterotrophs(other-feeders)?Autotrophs (self-feeders) are organisms that synthesize the biological molecules necessary for life support and digest inorganic substances from their environment using an external energy source. This kind of nutrition is found in plants that prepare their food through photosynthesis.
An organism that consumes other species in a food chain is known as a heterotroph (other-feeders). Heterotrophs cannot transform inorganic materials into organic ones, in contrast to autotrophs. They have to rely on a source of organic carbon that was once a part of a living thing. Heterotrophs depend on autotrophs either directly or indirectly for nutrients and food energy. This kind of nourishment is present in parasites, bacteria, fungi, yeast, humans, and other animals.
Therefore, in the cells of self-feeders and other feeders new inorganic and organic substances are created from energy

What structure seals the space between two cells and makes it impermeable?
The structure that seals the space between two cells and makes it impermeable is; Occluding or Tight Junction
What is the Cell Junction?
The correct answer to the question is called Occluding junctions or tight junctions. This is because Occluding junctions in cell structures are junctions that create a watertight seal that is like an impermeable or semipermeable barrier in between adjacent cells to prevent the escape of water or other liquids.
Thus, the structure is called an Occluding junction or tight junction.

A species with narrow niches that can survive in a small range of environmental conditions are
A. K-selected species
B. r-selected species
C. Generalist species
D. Specialist species
Answer:
D. Specialist Species
What is the advantage for species to be specialists, and how can they survive in the presence of opportunistic/generalist species?
In the setting of specialized habitats or unique situations, specialized species exist. When those conditions and surroundings change, they must adapt or go extinct, thus they must survive while they still exist.
When compared to generalists, they have the benefit of efficiency, which increases the likelihood of survival and, hence, reproduction within certain settings or situations. The generalists, on the other hand, have the benefit of being able to survive in a larger variety of circumstances and have a higher probability of doing so.
Cactuses, which are plants adapted to dry environments, are an example of specialization. More generalist plant species would typically outcompete cacti in most habitats on Earth, but very few of such species could endure the harsh conditions of a desert.
Extreme environmental conditions, competition for limited resources, and "evolutionary arms races" are some of the pressures that cause specialization. Cheetahs sprint quickly both because their prey moves quickly and because quicker cheetahs will be more effective hunters and more likely to procreate. The advantage of specialization is clear when seen from the standpoint of catching the next meal on a daily basis.
My key argument is that specialization's benefits must always be viewed in the context of the environment that generated the selective pressure that resulted in specialization. Although experts are specialists because they must be, their specializations put them in danger.
13. What two sub-processes do NADH and FADH2 cycle between? What do they do at each location?
NADH and FADH2 cycle is responsible for the production of small amount of energy in the form of ATP.
What occur in the NADH and FADH2 cycle?FADH2 and NADH are created through reduction-oxidation reactions in the Krebs cycle. This cycle produces small amounts of energy in the form of adenosine triphosphate (ATP), and also responsible for the production of compounds i.e. FADH2 and NADH. NADH produces 3 ATP whereas FADH2 produces 2 ATP molecules
So we can conclude that NADH and FADH2 cycle is responsible for the production of small amount of energy in the form of ATP.

Why socialist government turn authoritarian
The reason why socialist governments often turn authoritarian are:
Having too much power eventually corrupts the holder. When resistance builds, they try to suppress it because they feel socialism is the best way.Why does socialism sometimes become authoritarianism?Socialist governments tend to have too much power vested in the Executive in order to properly plan the economy.

Options:
A) Dinosaurs killed all other elephant species.
B) Asian and African elephants killed off other species of elephants.
C) Asian and African elephants adapted well to their environments.
Asian and African elephants adapted well to their environments. Thus, the correct option is C.
Environment of Antarctica is not suitable for elephants why?
The world's coldest location is Antarctica. Additionally, it is the windiest and driest. Almost the entire year, the continent is covered in snow. Due to the extremely harsh temperatures and lack of healthy soil, Antarctica is therefore unsuitable for raising elephants and cultivating crops. Elephants eat grass, while the entire continent of Antarctica is covered in snow. In this database, there are currently 25 (8,17) living elephants located in Australia.

B. Biodiversity has no effect on stability
C. More biodiversity increases stability
D. More biodiversity decreases stability
The ecology is absolutely necessary for biodiversity. Ecosystem stability also rises as a result of increased biodiversity.
What do you mean by biodiversity?
The term "biodiversity" is used to describe the variety of species that can be found on earth. It can include things like plants, animals, bacteria, fungi, and microbes. The diversity of life on earth is immense; while many species are still waiting to be discovered, many more have already gone extinct. The ecosystem is composed of every single living thing. It also covers their surrounding environment and how people interact with them.
