It is important to note that such animals living in desert conditions do not waste water by sweating to control body temperature. They mostly try burrowing during the day time to avoid getting dehydrated. Their urine is highly concentrated and it is mostly in the form of uric acid. These means help the desert animals to survive in such harsh conditions.
a. parsimony; simplest; fewest
When selecting among multiple possible phylogenetic trees that fit our data, we commonly use the principle of <u>parsimony</u>, which means we choose the <u>simplest</u> possible hypothesis. In phylogenetic analysis, that means selecting the tree that represents the <u>fewest</u> evolutionary changes or mutations.
Explanation:
Phylogeny describes the evolutionary history of on organism or group of organisms.
A phylogenetic tree structure is used to describe the relationship between various organisms which have originated from common ancestors.
The Principle of Parsimony is best applied while constructing phylogenetic tree.
This principle emphasizes on simple observations on a phylogeny which requires only few changes or variations which explain for the difference between the phylogenic sequences.
This tree structure will only have few specific genetic variations or mutations or evolutionary changes which took place through new appearance of a trait or disappearance of an existing trait.
- "This energy is usually in the form of low-level thermal energy. It is only possible to extract work when there is a temperature difference, so low-level thermal velocity; this means that the force of friction and the applied force are equal in magnitude."
- "An energy transformation is the change of energy from one form to another. Energy transformations occur everywhere every second of the day. There are many different forms of energy such as electrical, thermal, nuclear, mechanical, electromagnetic, sound, and chemical."
Answer:
Allosteric inhibition can be reversed.
The allosteric inhibitor binds to a site distinct from the active site resulting in decreased affinity of the enzyme for the substrate.
Allosteric inhibition can be irreversible
Answer:
In which phase of mitosis do chromosomes align at the center and spindle fibers become visible? Explanation: Mitosis involves four distinct stages: prophase, metaphase, anaphase, and telophase. Prophase is the first step of mitosis, during which chromosomes condense and the nuclear envelope dissolves.
