This is the unequal distribution of ions across a cell membrane.
Nady [450]

Answer:

Concentration gradient

Explanation:

Concentration gradient of the ions across the membrane generates the membrane resting potential.

Concentration gradient means that there is unequal distribution of the ions on different sides of membrane. For example, the concentration of K ions is much higher within the cell then out of the cell. Opposite is with the Na ions. When ions move from the area of their higher concentration to the are with the lower concentration, we say they move down the gradient or diffuse (no energy required). On the other hand, movement of ions against their gradient means that this process requires energy and involves protein pumps.

2. Members of this kingdom secrete enzymes into their food then absorb the digested matter
Fudgin [204]

Answer:

Fungi

Explanation:

Fungi are an example of saprotrophs i.e. organisms who live and feed on dead organic matter. Saprotrophic nutrition is described as chemoheterotrophic extracellular digestion. It involves the extracellular release of digestive enzymes on the organic matter. The enzymes break down the organic matter into a simpler form, which is then absorbed by the fungus.

nevsk [136]
Follicle stimulating hormone (FSH) and Luteinizing hormone (LH) are Gonadotropins stimulated in the gonads. In females, they are located in the ovaries. They are not needed for life yet important for reproduction. Progesterone which is being secreted in corpus luteum is needed for maintenance of pregnancy thus if a female has a low FSH and LH it will affect the chance of her be pregnant.
