Answer:
<u>Too much heat can disrupt subcellular structures such as membrane proteins, and enzymes while damaging the integrity of the plasma membrane.</u>
Explanation:
Proteins are macromolecules made up of amino acids. These fold and bond to form several biologically important molecules. For instance, enzymes, a special type of protein functions by <em>providing alternative reaction pathways. They work best at a specific pH and </em><em>optimal temperature range</em><em>, beyond which they become non-functional or denatured entirely. </em>
The denaturing of proteins occur at high temperatures, and alter protein folding, bonding and other types of behavior. Furthermore, membrane proteins are important for regulating cell function. If these are disrupted, the system cannot maintain homeostasis i.e a constant internal environment.
The answer is; C
This phenomenon is called bottleneck effect and drastically affects small populations in comparison to large ones. The mudslide wipes off most of the population B at the base of the hill base. Due to their small population, a large proportion of the population is lost and the pollution loses most of its alleles leaving a small proportion to continue the population succession. Its diversity is hence reduced as it repopulates. The larger population is not greatly affected because it covers much of the hillside.
Answer:
A scientist discovers a new organism in run-off from the Rio Tinto River in Spain (the river runs through a copper mine and the water has a pH of 2.0). On basic microscopic examination and after conducting a few simple experiments, she finds that this single-celled species is heterotrophic, has no cell wall, uses a flagellum for motion, and contains a variety of internal structures that are bound by plasma membranes. Given this information, this new species is most likely a <u>eukaryotic</u> cell in the <u>protozoan</u> subcategory
Explanation:
Eukaryotic cells contain nucleus and organelles and are enclosed by a plasma membrane. Organism that have these cells are protozoa, fungy, plants and animals.
Protozoan are single-celled eukaryotic.
