Research and identify a vestigial structure of an organism of your choosing.
Mariana [72]

Answer:

The one of best example would be appendix in humans.

Explanation:

In the past, the appendix may have helped in the digestion of the plants by producing mucus and prevent any type of infection. Plants with a high content of cellulose are digested with the help of the appendix as reported.

It is not a part of the human digestive system and considers as a vestigial organ. Vestigial organs are the organs that are present in an organism with no particular function and their removal will not lead to any harm. Humans do not need it because our digestive system is more efficient and works better in the first stages of digestion than they used to.

Thus, the correct answer is - appendix in humans.

Crossing over between non sister chromatids during meiosis is significant in heredity
suter [353]

Crossing over is the main event in meiosis and heredity as it leads to genetic variation.

<h3>What is genetic variation?</h3>

Genetic variation is the changes that take place in the genes of individuals that can lead to the formation of new characters.

it generally occurs in meiosis specifically during crossing over.

Thus, it can be concluded that crossing over between non-sister chromatids during meiosis is significant in heredity as it leads to genetic variation.

What is the determining factor for the transcription of structural genes of the trp operon?
padilas [110]

The right answer is 3. the availability of tryptophan in the environment

The TRP operon regulation depends on the availability of the tryptophan molecule (it depends if the cell need tryptophan or already has it).

There are two modes of regulation of the trp operon: Suppression and Mitigation

*Repression

The synthesis of operon mRNA is controlled by a repressor that blocks transcription when bound by tryptophan, which acts as a co-repressor.

The repressor, a 108 aa homodimer (ie 2 apo-repressor), has helix-turn-helix domains that interact with inverted repeats at the major groove of the operator, thus allowing its fixation.

In the absence of trp, the repressor is inactive and does not attach to the operator. The RNA polymerase can bind to the promoter and transcribe the trp E, D, C, B, A structural genes.

In the presence of trp, the repressor changes conformation and becomes active, so it binds to the operator, preventing RNA polymerase from accessing the promoter so transcription will not occur.

* The Attenuation

This is a premature termination of transcription that is a function of Trp concentration. It takes place at a late moment of transcription while regulation by repression is done during the initiation.

1st Case: Low Trp Rate, Continuous Transcription, → Formation of the Anti-attenuator in the absence of trp, and therefore the synthesis of tryptophan is continued.

2nd case: High rate of trp, stop transcription, → Formation of the attenuator in the presence of trp. This one will attenuate the synthesis of tryptophan.

alexgriva [62]

Answer:

What is the main advantage to using satellites to measure climate change?

Explanation:

answer A...Satellites in a low earth orbit can directly monitor the climate from their position within or just above the atmosphere, and can provide near-global coverage as they scan over different swathes of ground with each orbit.
