Answer:
Population studies look at factors for one individual species.
Explanation:
In a garden, there are multiple species of plants growing. You could study different factors of each population, which is just all the individuals of one species in an area. For example, you could study how adding fertilizer affects the growth of tomato plants. To do this, you would have some tomato plants in the garden that have fertilizer added to the soil and some that don't. At the end of a certain period of time, maybe a month, measure the plants, find the average height and compare their growth. This is just one example, but there are lots of different things you could study.
Answer:
<h2>Form cellular extensions</h2>
Explanation:
Actin filaments are linear chain of globular actin (G-actin) subunits.
Actin filaments occur as microfilaments in the cytoskeleton inside the cell membrane, which are part of the contractile apparatus in muscle and non-muscle cells and various other type of cells.
Actin filaments are particularly abundant beneath the plasma membrane, they form a network that provides mechanical support, they determines cell shape, enabling cells to migrate, engulf particles, and divide.

Answer:
nearly one million tons per year
Explanation:
Midgely would receive the Society of Chemical Industry’s Perkin Medal for this research in 1937; in 1941, he was awarded the Priestley Medal, the American Chemical Society’s highest award, for his contributions to chemistry.
By the early 1970s, CFCs were in widespread use, and worldwide production of the compounds had reached nearly one million tons per year, representing roughly a $500 million slice of the chemical industry.
