Ascientist wants to grow human cells to use in an experiment. what should the scientist do to grow and maintain cells in the laboratory? apex

The scientist should prepare a culture of the cells

Explanation:

The scientists should prepare a culture of the human cells. It also requires special ingredients like subtrate or medium that will supply essential nutrients like amino acids, vitamins, minerals and carbohydrates to the cells. Growth factors, hormones, important gases like carbon dioxide and oxygen are also required. A regulated environment supported by appropriate pH, temperature and osmotic pressure is also desired for the growth of cells.

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !
