The temperatures on land change more rapidly than temperatures on water.
1-The air above sand warms up and rises during the day because the land heats up more quickly than the sea, while the cool air above the water travels towards the land to take its place.
2- During the night, the land cools more quickly than the sea, which causes hot air above the sea to rise and be replaced by cool air above the land. Therefore, the temperature on land changes more quickly than temperature on water

Does the ability of chiromantis frogs to resist water loss most likely represent acclimatization or adaptation?
The ability of chiromantis frogs to resist water loss most likely represent Adaptation.
Most frogs sweat at the same rate that water evaporates from a surface of free water. Despite this, there is a remarkable variety of terrestrial settings where frogs can be found, including deserts. Most frogs have not evolved a resistance to cutaneous water loss due to the significance of moist skin for respiration is adaptation.
The rate of water loss in arboreal species, such as the genus Chiromantis, is extremely low and comparable to that of desert reptiles. The "water-proof" frogs are a phrase used to describe this species. It even consists of specialized guanine-rich chromatophores.

High frequency vibration is sensed by muscle spindles which initiates a contraction in the surrounding muscle tissue. why?
High frequency vibration is sensed by muscle spindles which initiates a contraction in the surrounding muscle tissue because muscle spindles are falsely detecting a change in length.
Functionally, muscle spindles are stretch detectors. Vibration can cause muscle lengthening and shortening, potentially resulting in increased muscle tension due to a stretch reflex.
When a muscle is stretched, this change in length is transmitted to the spindles and their intrafusal fibers which are subsequently similarly stretched.
The responses of muscle spindles regulate the contraction of muscles, by activating motor neurons via the stretch reflex to resist muscle stretch.

Polysaccharide digestion and glycogen breakdown involve sequential cleavage from ________ ends of glucose polymers.
Sequential cleavage from the non-reducing terminals of glucose molecules is required for both glycogen degradation and polysaccharides hydrolysis.
Why non-reducing end is selected for digestion?
A polysaccharide's non-reducing end is the one where an anomeric carbon participates in the glycosidic connection. The elimination of carbohydrate remnants one at a time out from the non-reducing terminal occurs during glycogenolysis and polysaccharides hydrolysis.
For example, several enzymes are involved in glycogenolysis in the liver and muscle. An example of such an enzyme is glycogen phosphorylase, which catalyzes the successive dissociation of the alpha 1->4 glycosidic bond that connects two glucose molecules at a non-reducing terminal of glycogen. The last glucose residue is eliminated as alpha-D-glucose 1-phosphate.That is why non-reducing end of glucose is chosen for digestion or breakdown of the carbohydrate polymer.

Any cell's DNA can be changed by radiation. Somatic or nonheritable effects refer to cell damage and death brought on by mutations in somatic cells that solely affect the organism in which the mutation occurred.In the event that ionizing radiation contacts with a DNA macromolecule, the energy released may cause a chemical bond to be broken and may even sever one of the sugar-phosphate chain side rails, or strands, of the molecular structure that resembles a ladder (single-strand break). A point mutation is the term used to describe this kind of DNA damage.By causing DNA breaks, especially double-strand breaks (DSBs), ionizing radiation directly changes DNA structure.
