When populations share the environment and interact with the other populations of different living species present in the same are, it is called an ecological community. Thus, the correct option is B.
An ecological community is defined as the group of species which are commonly found together in an area. Ecological communities may include animal or plant assemblages with the similar habitat requirements and contain species which may interact with each other or rely on the similar processes in their particular environment.
An example of ecological community is a forest community which comprises of all the trees, the plant community, birds, deer, squirrels, foxes, fungi, insects, and other local or seasonal species.
Therefore, the correct option is B.

Answer:
A
Explanation:
its an ecosystem; reaction between living things and their environment
Answer:
The Basophils
Explanation:
Basophils are a type of white blood cells that arise from the bone marrow and can be found in most tissues. They respond to inflammatory reaction particularly allergic reaction and hypersensitivity reactions. When activated they degranulate to release histamine and proteolytic enzymes.
They are related to connective tissues because they contain similar granules.
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.
True statements: A (Water is made up of atoms bonded to form molecules) and D (The chemical formula for water is H₂O).
False statements: B (Water contains half as many hydrogen atoms as oxygen atoms) and C (Water molecules tend to push away from each other)
Let's examine each statement to determine its accuracy:
A) Water is made up of atoms bonded to form molecules.
True: Water is indeed composed of molecules. Each water molecule consists of two hydrogen atoms covalently bonded to one oxygen atom, forming the H₂O molecule.
B) Water contains half as many hydrogen atoms as oxygen atoms.
False: The chemical formula for water, H₂O, indicates that there are two hydrogen atoms for every one oxygen atom in a water molecule. Therefore, water contains twice as many hydrogen atoms as oxygen atoms.
C) Water molecules tend to push away from each other.
False: Water molecules exhibit a property called cohesion, where they are attracted to each other due to hydrogen bonding. This attraction causes water molecules to "stick" together rather than push away from each other. It's why water forms droplets and has a relatively high surface tension.
D) The chemical formula for water is H₂O.
True: The chemical formula H₂O accurately represents the composition of water, indicating that each water molecule consists of two hydrogen atoms and one oxygen atom.
The structure of water involves H₂O molecules, with each molecule consisting of two hydrogen atoms and one oxygen atom, and water molecules exhibit cohesion due to hydrogen bonding, causing them to attract and stick together.
