Answer:
Biotic factors such as the presence of autotrophs or self-nourishing organisms such as plants, and the diversity of consumers also affect an entire ecosystem. Abiotic factors affect the ability of organisms to survive and reproduce. Abiotic limiting factors restrict the growth of populations.
Explanation:
Proteins that assist in the movement of substances across can be classified into two types which are:
<h3>What are Proteins?</h3>
These are biological molecule which consists of amino acid sequences and are involved in metabolic activities in the body.
They are also found in cells and help in the selective movement of molecules in and out of the cell.

The correct answer is B. Ribosome
Explanation:
In biology, cells are mainly classified as eukaryotic or prokaryotic. Each of these types of cells has different features, to begin with, eukaryotic cells are those that contain a defined nucleus and are part of both unicellular and multicellular organisms. On the opposite, prokaryotic cells do not have a defined nucleus or a nuclear envelope and are mainly present in unicellular organisms, besides this, they lack mitochondrion, Golgi apparatus or chloroplasts that are present in eukaryotic cells. However, prokaryotic cells still contain DNA, ribosomes, vesicles, and vacuoles. According to this, the one that is present in a prokaryotic cell is ribosome.
Answer:
32 mm
Explanation:
The field of view is the total area visible through the microscope
. The diameter of the field of view can be measured.
There is an inverse relationship between the magnification and the field diameter. As magnifications decreases, the field diameter increases by the same proportion, and as magnifications increases, the field diameter decreases by the same proportion.
The relationship between field diameter and magnification is:
magnification of A * field diameter of A = magnification of B * field diameter of B
120X * 8 mm = 30X * B
B = 120X / 30X * 8 mm
B = 32 mm = 32000 μm
The field diameter of 30X magnification is 32 mm (32000 μm)
