Answer:
<h3>Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. Unicellular organisms include bacteria, protists, and yeast</h3>
Answer:
Glycerol!
Explanation:
Triglyceride is an Ester, that is formed by the reaction between 1 glycerol and 3 fatty acid molecules, it's commonly known as fat. It act as storage for energy in the human body and as well as provides insulation. It also absorbs fat - absorbing vitamins in the body. When body needs more energy , it breaks down fat by the process of lipolysis into fatty acids and glycerol and release them in the blood.
Answer:
The organisms have a common ancestor
Explanation:
Homologues structyres conclude that organisms of different species share structures, making them all have some sort of common ancestor
9. A mesoderm is a germ layer that arises during gastrulation and is the middle layer of the embryo. An example of inverterbrate with mesoderm is
an earthworm

For unicellular organisms, cell division is important for the reproduction of the population, Unicellular organism mainly use cell division, also called binary fission, for pollution growth. This is because unicellular organisms are only composed of one cell.
Multicellular organisms use cell division for growth and reproduction. Cell division causes increase in the number of cells composing the organism hence its growth in size. Cell division is also used to create gametes that are used in reproduction by fertilization.
(2)
Even in fully developed organisms, cell division is important in tissue repair. In tissue homeostasis, there is a balanced rate of cell division and cell death . An example in muscles. Due to the stress experienced by muscle cells, they usually have a lower life span and therefore the damaged cells are often replaced with new ones by cell division. This prevents tissue wastage.
(3)
Growth factors signal the growth of a cell. They usually bind receptors on the cell surface and indicate how the cell should grow and divide base don environmental stimuli. An example is during regular exercises. Growth factors indicate that the muscle cells should divide regularly and grow bigger to accommodate the higher stress in the muscles from the workout. This is how your muscles grow bigger and stronger with more exercise.
(4)
Differentiation of cells occurs through the silencing of some gene allowing the cell to produce particular proteins (and other biomolecules) that align with its functions in the body. This especially critical in multicellular organisms. An example is that while al the cells in your body have the same DNA, some cells differentiate into liver cells while others into lungs, stomach, heart, and etcetera.
