They are kind of. Octopus are kind of related to arthropods, and have 8 tentacles/legs, so I guess you called call it that? Not really, though.

You perform an experiment in which you take 16 pots of strawberry plants and give half of them 1 gm of ammonium nitrate per lite

svetlana [45]

Answer:

homeostasis.

Explanation:

Homeostasis is the process whereby living systems maintain a stable internal environment despite changes in environmental conditions. Plants, like every other living organisms also perform this process to keep their internal environment in a stable state.

According to the question, some plants were exposed to ammonium nitrate, which serves as a nutrient, and 16 hours of sunlight needed for photosynthesis to take place. The plants exposed to ammonium nitrate and 16 hours sunlight grew taller because they had access to nutrients needed to bring about the process of photosynthesis, which provides the plant with energy source (Glucose).

The uptake of nutrients like ammonium nitrate by the plants is done in order to maintain a homeostatic internal environment. Without nutrients, which is the purpose of the ammonium nitrate, plants cannot grow. Hence, the plants exposed to ammonium nitrate, take it in to keep their internal environment functioning.

Sort the different barriers into their modes of reproductive isolation. A snail with a flat disc-like shell will not be able to

Stella [2.4K]

Answer/Explanation:

Types of reproductive isolation include: temporal, ecological, mechanical, and behavioural.

A snail with a flat disc-like shell will not be able to mate with a snail having a conical shell - this is an example of mechanical isolation, where the animals are physically unable to mate due to incompatible body shapes and sizes.

The reproductive organs of male bush babies do not match with the reproductive organs of females of other bush baby species. - this is another example of mechanical isolation, as the sexual organs will physically not allow reproduction between these species

The mating call of a cricket is not recognized by a cricket of other species - this is an example of behavioural isolation, which results from incompatible mating rituals. I.e. the animals do not respond to each others mating behaviours

The signals sent by a male firefly are not recognized by the female firefly of other species. - this is also an example of behavioural isolation.

Temporal isolation is where species cannot interact because they do not have the same mating seasons or are not active at the same type of day. ?Ecological isolation occurs when two species do not come into physical contact to one another because they access different areas of the habitat. E.g. mating zones, food sources or nesting sites.

A particular protein largely lacks both secondary and tertiary structure. which factor, if any, is mainly responsible for the re

NemiM [27]

Entropy, is mainly responsible for the resting state of this protein.

Hydrogen bonds, disulfide bonds, and dipole-dipole interactions produce the complicated folding styles seen in secondary and tertiary structure. however, if a protein does not have these elements of structure, it'll undertake a kingdom in which its entropy is maximized.

Secondary shape is determined through hydrogen bonding within the amino acid chain backbone. Tertiary structure is the entire protein's form, decided Entropy Interplay and hydrophobic forces. The tertiary shape of a protein is the 3 dimensional shape of the protein. Disulfide bonds, hydrogen bonds, ionic bonds, and hydrophobic interactions all affect the form a protein takes.

The nonpolar amino acids have formed the nonpolar center of the protein, weak van der Waals forces stabilize the protein. furthermore, hydrogen bonds and ionic interactions between the polar, charged amino acids make a contribution to the tertiary structure.

A. Entropy

B. Hydrogen bonds between amino acid residues

C. Dipole-dipole interactions

D. None of the above
