Answer:
3) passive transport
Explanation:
Passive transport is a type of cellular transport that does not require the use of energy to move substances (i.e., ions and molecules) across biological membranes. Passive transport uses concentration gradients to move substances across cell membranes, thereby transporting them from regions of high concentration to regions of low concentration. Passive transport can be divided into 1-osmosis (i.e., movement of solvents), 2-diffusion (i.e., movement of solutes), and 3-facilitated diffusion (i.e., movement of molecules with help of protein channels or carriers), and 4-filtration (i.e., movement of water by using a pressure gradient).
Bacteria is not included as an abiotic factor in an ecosystem.
Answer:
Graafian follicle
Explanation:
Ovulation is the process observed in the females during which the females release the oocyte or the female egg cell. The process of ovulation takes place every month during the 14th day of the menstrual cycle.
The primary follicle is formed in the females before birth but after the puberty, each month the primary follicle matures into the secondary and then tertiary follicle called the Graafian follicle. This Graafian follicle releases the secondary oocyte.
Thus, Graafian follicle is the correct answer.
E. coli is a micro-organism while is mobile, and possess flagella for the same It has the ability to ferment both glucose and lactose. But it can not utilize citrate. It is a common food-borne pathogen, and can be present due to poor hygienic conditions, or water contaminations.
