The
kidneys can have a direct influence on blood pH, by pushing hydrogen ions and
bicarbonate into and out of urine.
<span>Regulation
of blood pH or acid-base homeostasis is maintained by kidneys. Kidneys regulate
pH by excreting hydrogen ions (H</span>⁺<span>) into the urine and reabsorbing bicarbonate (HCO3</span>⁻<span>)
from the urine. <span>Acidosis (low blood pH) causes more
bicarbonate to be reabsorbed and in response to alkalosis (high blood pH) kidneys
excrete more bicarbonate.</span></span>
B. They come from other living cells because all living things come from other living things.
<u>Answer:</u>
Humus increases the soil's porosity and water-holding capacity and helps to buffer rapid changes in soil acidity. Humus also helps the soil to hold its nutrients, increasing its fertility. Fertile soils are rich in nitrogen, contain a high percentage of organic materials, and are usually black or dark brown in color.

True. The term hominin refers to modern-day humans and our fossil relatives that are more similar to us than they are to chimpanzees.
<h3>What is hominin?</h3>
- Hominins are our direct predecessors, extinct human species, and modern humans collectively (including members of the genera Homo, Australopithecus, Paranthropus and Ardipithecus).
- A member of the family Hominidae, which includes humans, gorillas, chimpanzees, and orangutans, is referred to as a hominid.
- A member of the subfamily Homininae, which includes humans, gorillas, and chimpanzees, is a hominine (excludes orangutans).
- A hominin is a chimpanzee or human who belongs to the Hominini tribe.
- Three distinct taxonomic levels were established for chimpanzees, gorillas, and humans.
- Humans are a member of the Hominini, sometimes known as hominins.
- The primary distinction between hominid and hominin is that the former refers to the family to which humans belong while the latter refers to the level of the tribe to which humans belong.
