Answer: Receptor
Explanation: A virus can latch onto a receptor, which gives it access to attach and inject their genetic material.
The substance is required by all living things and is involved in many processes that occur in all living things.
Answer:
The equation represents a biological process that is Photosynthesis. This process is done by plant cell in their chloroplast.
Expanation:
Plants contain Chlorophyll Pigment that helps in the process of photosynthesis( a biological process through which plants can produce their own food with the help of sun light, Carbon dioxide and water and form glucose and oxygen).
This process takes place in chloroplast which contain double membrane with many folds. The double membrane encloses a structure called thylakoid that contain pigment chlorophyll. The function of chloroplast is to capture light that is required in the process of photosynthesis.
Waters Lower density while in a solid form is due to how the hydrogen bonds are formed as it freezes, water molecules are apart compared to liquid water. The structure of ice makes it less dense than free flowing molecules in the liquid water, giving it the ability to float on water.
Ribosomes produce the proteins
