Answer: cell wall structure
Explanation:
Answer:
A plant cell have a vacuole, chloroplasts and A cell wall
Vacuole - Gives the cell shape
Chloroplasts - Contain a green pigment (turns the plant green) To do with photosynthesis.
Cell Wall - Holds the cell up and keeps it in a rigid structure.
The correct answer is option C. It causes water molecules to be attracted to other water molecules.
The water is a polar molecule. The polarity of the water is due to the electronegativity of the oxygen. Due to high electronegativity of the oxygen the bond of the hydrogen and oxygen is pulled towards itself, which causes the appearance of slight negative charge on the oxygen and slight positive charge on hydrogen.
Due to this slight charge, the water molecules are attracted towards one another and form hydrogen bonds.
Answer:
B. It contains lymphocytes
Explanation:
Lymph is a clear to white fluid made of white blood cells, especially lymphocytes. The cells that attack bacteria in the blood and body tissues. The lymph is a part of the vascular system of our body.
Lymph, part of the lymphatic system, contains lymphocytes and removes waste from the body. However, contrary to option D, it is not filtered in the kidneys.
The statement which is not a characteristic of lymph is: D. Lymph is filtered in kidney. The lymphatic system collects extracellular fluid and returns it to the bloodstream, moving it in a single direction - from the body's tissues to the heart. It's composed of lymph fluid which contains lymphocytes, a type of white blood cell. Lymphocytes play a key role in the immune response, which marks option B as true. Also, the lymphatic system is involved in waste removal, supporting statement C. However, statement D that lymph is filtered in the kidneys is false. Lymph is not filtered by the kidneys, unlike blood that is directed through the kidneys for filtration.

Answer:
Prokaryotes are the most primitive form of life that exist on earth. They came before eukaryotes.
The main difference is the presence of nucleus which is present in eukaryotes and absent in prokaryotes.
The genetic material of prokaryotes are dissolved in the cytoplasm whereas in case of eukaryotes the genetic material is in-tacked inside a double membrane organelle nucleus.
There are many more membrane bound cell organelles found in eukaryotes that are absent in prokaryotes.
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.
