Which two extinction risks may be a direct result of the pet trade?

Biology
1 answer:
irga5000 [103]3 years ago
4 0

Answer:

overharvesting and exotic species introduction

Explanation:

The pet trade is one of the main threats to biodiversity on the planet and can cause the extinction of several species in the medium and long term. Trade in extinction animals often involves wild species being removed from their natural habitat to another habitat entirely different from yours.

This trade, in addition to causing the species to shrink in their natural habitat, can lead to the introduction of exotic species that can become a pest and end up with the extinction of another species.

Suppose only one gene with 2 alleles determines a particular trait but the alleles are codominant. how mant different phenotypes
Leona [35]

The answer is one trait. In Codominant alleles, neither allele is dominant over the other. Both alleles are expressed equally hence no recessive or dominant phenotypes. An example of that of fur color in rabbits where one  parent with black fur color and the other with white fur color will produce offspring of black and white fur color. This should not be confused with incomplete dominance  whre the two alleles blend in phenotype.Example of incomplete dominance is a parent with straight hair in humans and another with curled hair will produce wavy hair offsprings.

A genetic engineer wants to isolate a gene from a scorpion that encodes the deadly toxin found in its stinger, with the ultimate
slamgirl [31]

Answer:

The correct answer is - Yes, the genetic engineer should create a genomic library or a cDNA library.

Explanation:

mRNA isolated from the toxin extracted from the venom gland of the scorpion to create a cDNA library. The cDNA sequence is reverse transcribed by the mRNA that lacks the introns as prokaryotic organisms such as bacteria cannot splice introns.

If the engineer wants to express the toxin in bacteria then he required a cDNA sequence as a genomic clone can not use to clone for making proteins.  mRNA should be isolated from the venom gland so it can synthesize cDNA library enriched with toxin protein sequence.

what is the function of vesicles in the synthesis of proteins and the release or those proteins outside the cell?
Zina [86]

Vesicles transport newly synthesized proteins to the Golgi apparatus. After the Golgi apparatus modifies the proteins, vesicles transport the modified proteins to the cell membrane, where they are released.

Hope this helps!
