Answer:
The microbes thriving in acidic environments are termed as acidophiles, and these range from eukaryotes to bacteria and archaea, which are mainly found in diverse acidic surroundings like sulfuric geysers and pools, in the human stomach, and in the regions that get polluted by acid mine drainage.
The mentioned case is not entirely correct as the protons found in the acidic surroundings are not utilized for the generation of ATP as they are not originating from within the cell. In order to sustain their internal acidic pH, the acidophiles exhibit adaptations like the presence of the negatively charged proteins on the surfaces of their membranes so that they can prevent deterioration due to acidic surroundings.
Answer:
Its cells have thick, hard walls.
Explanation:
Answer:
Type I curve
Explanation:
The K-strategist are species characterized by relatively stable populations that fluctuate at the carrying capacity of the habitat or niche in which organisms reside. Elephants are considered as K-strategists because they have a low population growth rate and relatively stable populations. There are three different types of survivorship curves. The Type I curve (also referred to as A curve) is characteristic of k-strategist organisms. Humans and elephants exhibit a Type I survivorship curve in which organisms tend to die when they become elderly. These species have a small number of offspring and provide parental care to ensure their survival. In a Type II survivorship curve, species produce many offspring and only some offspring survive (e.g., birds), while in Type III survivorship curve organisms produce many more offspring and most do not survive (i.e., r-strategists such as frogs or insects).
I was debating this question for the longest time and I came up with a conclusion.
No
Answer:
The regulation of the cell cycle helps in wound healing as well as replacing the lost cells by division. Thus, options B and C are correct.
Explanation:
The cell cycle can be described as the process of division and reproduction. The events result in the formation of multiple cells that have been able to deal with the repair mechanism of the body.
With the regulation of the cell cycle, the division process of the cell has been initiated and helps in the formation of multiple cells. The formed daughter cells have been able to heal the wounds effectively by accumulating and removing the dead cell.
The cell cycle has also been responsible for the replacement of lost cells, with the formation of new cells. Thus, options B and C are correct.
