Explanation:
they differ because it doesn't hurl multi-cellular organisms if one cell dies but if a single celled organism looses its one cell that organism will die.
One
substance, other than the secretions from nerve cells, that is used in cell
communication are hormones.

To
add, <span>a hormone is any member of a class of signaling
molecules produced by glands in multicellular organisms that are transported by
the circulatory system to target distant organs to regulate physiology and
behaviour.</span></span>
Answer:
D. realize that lethargy in an infant is always an ominous neurological sign and immediately assess him.
Explanation:
Lethargy in infants can be seen in several ways. one of this is that the child may be sluggish and as if he or she has little or no energy. the child may find it difficult to be awake for feeding.

Therefore the last option is the best option for the nurse to take.

Answer:
A. Sexual reproduction
Explanation:
A multicellular organism is made up of more than one cell. Humans, animals, and plants are all examples of multicellular organisms. Groups of cells form tissue, groups of tissue forms organs, groups of organs form systems.
Unicellular organisms receive material directly from their environment. Multicellular organisms have systems for moving materials throughout their body. Unicellular organisms can perform all of life’s functions within a single cell. Multicellular organisms have many cells that each perform a special function. Cells develop into their mature forms through the process of cell differentiation. Cells differ because different combinations of genes are expressed. Organs are groups of tissues that perform a specific or related function. Organ systems are groups of organs that carry out similar functions.
For example, stem cells are classified into three types: totipotent (or growing into any other cell type), pluripotent, or growing into any cell type but a totipotent cell), multipotent (or growing into cells of a closely related cell family).
