6 0

Answer:

75%

Explanation:

The mom only carries the gene for blue eyes. The dad carries the gene for blue eyes, and the gene for brown eyes.  So hypothetically speaking (because Punnet squares are only guesses/predictions) 75% of the kids could have blue eyes

Which molecule prevents a muscle contraction from occurring when the muscle is at rest?
AysviL [449]

Troponin-tropomyosin molecules prevents a muscle contraction from occurring when the muscle is at rest.

<h3>What is muscle contraction?</h3>

The activation of tension-producing regions within muscle cells results in muscular contraction. Because muscle tension can be created without changes in muscle length, such as when holding something heavy in the same position, muscle contraction does not always imply muscle shortening in physiology. Muscle relaxation, or the return of the muscular fibers to their low tension-generating state, occurs after a muscle contraction has finished.

Both length and tension can be used to characterize muscle contractions. If the muscle tension varies but the muscle length doesn't, the muscle contraction is said to be isometric. A muscle contraction is isotonic, however, if the tension in the muscle remains constant during the contraction.

Two species of similar-looking insects have the same coloration, although one is poisonous and the other is not. This is likely
Vadim26 [7]

Answer:

The correct answer is option d, that is, mimicry.

Explanation:

Mimicry in evolutionary biology refers to an evolved similarity between the organism and another organism of other species. The phenomenon may take place between the individuals of a similar species or between the individuals of distinct species. The main objective of mimicry is to safeguard the species from predators, resulting in an antipredator adaptation.  

The evolution of mimicry takes place when the predator witnesses a similarity between the model and the mimic and as a consequence modifies its behavior in a manner, which offers a selective benefit to the mimic.

As a ribosome translocates along an mrna molecule by one codon, what happens after it?
erastova [34]

Answer:

The tRNA is released from the E site of the ribosome and the elongation process finishes while the termination process starts.

Explanation:

When the translocation process is finished the tRNA that is in the E site  of the ribosome is released and the A site of the ribosome reads a stop codon in the mRNA in order to finish the elongation process and start with the termination process.  In the termination process  a termination factor joins the stop codon, the ribosomal subunits split apart, the protein and the tRNA dissociate from one another and the tARN is not in the P site of the ribosome anymore.
