Answer:
In some communities, the phenomenon of competition can easily be depicted as compared to other communities. In some communities, there will be enough resources available and hence, these communities will have a fewer competition to be recognized. In other cases, some communities might require evolutionary changes to occur for the depiction of a competition. In such scenarios, it will be difficult to recognize competition at the time of its existence.
flagella for movement
distinct nucleus
membrane-bound organelles
Prokaryotes are single-celled organisms that use flagella for movement. They do not have a distinct nucleus or membrane-bound organelles, unlike eukaryotes. Their DNA is often circular and not organized in chromosomes.
The characteristics of prokaryotes listed include their being single-celled and their use of flagella for movement. However, prokaryotes don't have a distinct nucleus, rather they have a region known as nucleoid where their DNA is located. Also, they lack membrane-bound organelles. They are simpler in structure compared to eukaryotic cells. Their DNA is often circular and not organized in chromosomes as in eukaryotes.

A habitat contains biotic and abiotic factors.
Most organisms can survive if they are taken away from their habitat.
A habitat has specific characteristics that an organism needs to live there.
An organism's habitat is the place where it lives and contains both biotic and abiotic factors. Removing an organism from its habitat can disrupt its ability to survive.
The statement 'Most organisms can survive if they are taken away from their habitat' is not true.
An organism's habitat is the place where it lives and it contains both biotic (living) and abiotic (non-living) factors. A habitat has specific characteristics that an organism needs to live there, so removing an organism from its habitat can disrupt its ability to survive.
For example, a polar bear relies on its Arctic habitat for food (seals) and shelter (icebergs). If it was taken away from its habitat and placed in a desert habitat, it would not be able to find its usual food source or endure the extreme heat.

hydrophillic head, hydrophobic tail, hydrophobic tail, hydrophillic head
Answer:
The correct order would be a hydrophilic head, hydrophobic tail, hydrophobic tail, and hydrophilic head.
The plasma membrane is a lipid bilayer, that is, a layer formed of two layers of phospholipids.
A phospholipid is made up of two parts; hydrophilic polar heads and hydrophobic lipid tail.
The two layers are arranged in such a way that the hydrophilic parts are present outwards and the hydrophobic tails are sandwiched between the polar heads of two layers.
Thus, the order would be a hydrophilic head, hydrophobic tail, hydrophobic tail, and hydrophilic head.
The exchange of genetic material between organisms living at the same time in the same environment is known as horizontal gene tratransfer. This process, along with gene flow, contributes to genetic diversity and reduces the risk of extinction.
Genetic exchange between organisms living at the same time in the same environment is considered to be Horizontal gene transfer. This concept involves the introduction of genetic material from one organism to another within the same generation. It is different from vertical gene transfer, which is the transmission of genetic information from generation to generation. Horizontal gene transfer allows even distantly related species to exchange genes, impacting their phenotypes. Gene flow is another related concept, which involves the exchange of genetic material between populations, contributing to genetic diversity and reducing the risk of extinction.

As a galaxy gets farther away from Earth it gets faster.
Explanation:
First, moving away “from the Earth”. They certainly aren’t going away from the Earth. Everything is moving apart from everything else. No matter where you are in this expanding world, everything else will seem to be dropping from you. The space in within the galaxies is expanding! And the farther away a universe is the more space there is to increase so the faster the galaxy appears to move away from us.
