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.

Describe how enzymes influence metabolic reactions in the cell.
Genrish500 [490]

Answer:

Enzymes are biological catalysts that increase the rate of chemical reactions inside cells by lowering the activation energy required for the reaction to proceed. In nature, exergonic reactions do not require energy beyond activation energy to proceed, and they release energy.

A mutation within a gene that will insert a premature stop codon in mrna would _______
AveGali [126]

A mutation within a gene that will insert a untimely cease codon in mRNA would result in a shortened polypeptide chain.

<h3>What occurs if there is a untimely end codon?</h3>

Thus, nonsense mutations occur when a premature nonsense or end codon is added in the DNA sequence. When the mutated sequence is translated into a protein, the resulting protein is incomplete and shorter than normal. Consequently, most nonsense mutations result in nonfunctional proteins

<h3>What mutation motives untimely cease codon?</h3>

In genetics, a nonsense mutation is a factor mutation in a sequence of DNA that effects in a premature stop codon, or a nonsense codon in the transcribed mRNA, and in a truncated, incomplete, and normally nonfunctional protein product.
