Answer:
Biotic: <em>Food availability</em>
Abiotic: <em>Temperature</em>
Explanation:
There are two types of limiting factors for biodiversity: biotic and abiotic. Biotic refers to living things, for example, organisms that are an important food source. <u>Most animal life forms in the ocean highly depend on the availability of a food source</u>. If food is limited or scarce, the populations of a given species could face significant declines.
On the other hand, there are abiotic factors, which refer to factors that are not alive, such as physical factors. For instance, temperature and light. <u>For marine organisms, temperature is a critical factor.</u> Even an increase of 'only' 1 ºC could make a huge difference in the survival of a species as it could disrupt their ability to forage, hunt, or perform physiological processes, <em>e.g.</em> metabolism.
Therefore, <u>if we refer to a biotic factor, food availability is a limiting factor for most animal life in the open ocean, whereas, if the refer to an abiotic factor, temperature (and light) are limiting factors for pelagic life.</u>
Answer:
The correct answer will be- epimysium
Explanation:
Epimysium is the fibrous connective tissue envelope which surrounds the muscle fibers of the muscle as a whole.
The epimysium plays an important role in maintaining the muscle structure as it protects the muscle from the friction caused by the associated bones and the muscles.
The epimysium is continuous with other layers called the endomysium, perimysium, tendons and the fascia.
Thus, epimysium is the correct answers.
Answer:
The light is shifted to the red end of the spectrum, as the wavelengths get longer.<em> </em>
Answer:
C. The enzyme with mutation 1 has decreased affinity for pyridoxal phosphate, whereas the enzyme with mutation 2 has lost the ability to bind to the substrates.
Explanation:
A coenzyme is an organic cofactor that binds with an enzyme in order to initiate or aid the function of the enzyme. A coenzyme binds to the active site of the enzyme (where the reaction occurs), thereby triggering its activation by modifying protein structure during the reaction. Some examples of coenzymes include Coenzyme A and Adenosine triphosphate (ATP). Pyridoxal phosphate is a coenzyme (it is the active form of vitamin B6) that is required for the function of cystathionase. Moreover, cystathionase is an enzyme that enables cells the synthesis of cysteine from methionine (transsulfuration pathway). The binding of pyridoxal phosphate to the enzyme increases the binding affinity of the enzyme for the substrate, thereby influencing its activity. In this case, it is expected that mutation 1 reduces the binding affinity of the enzyme to the cofactor, and thereby the cofactor is required at a higher concentration to restore normal enzyme activity.
