Rama09 [41]

Answer:

Wildfire

Explanation:

The wildfires are one very devastating occurrence that can appear both naturally and be caused by humans. Naturally these fires occur because of high temperatures and drought, and because of thunders. When they occur, they spread out very quickly and it is an uncontrolled fire. It manages to burn down very large areas of grasslands or forests, moving very quickly and being extremely difficult to put it under control. While the wildfires are very destructive, there's also a positive from them, as they leave behind lot of ashes, and the ashes fertilize the soil, providing the basis for the growth of new vegetation.

TRNA molecules bring a specific ________________ to the ribosome, according to the ______________. *
Veronika [31]

Answer:

tRNA molecules bring a specific <u>amino acid</u> to the ribosome, according to the <u>mRNA codon</u>.

Explanation:

In the context of protein synthesis, an mRNA molecule contains the specific codons that encode the amino acids that will be part of the protein. The tRNA is in charge of bringing the amino acids to the ribosome, according to the specific information of the mRNA codons.

The function of tRNA depends on the complementarity that exists between the mRNA codon and the anti-codon tRNA, in such a way that :

  • <em>The pattern in the amino acid sequence of a protein is indicated by mRNA </em>
  • <em>tRNA has a complementary anticodon, so it will only bring the specific amino acid that the codon encodes.</em>

In general terms, each mRNA molecule possesses the genetic code that indicates the amino acid sequence of a protein, and tRNA helps bring those amino acids to the ribosome for synthesis to occur.

A parent with the blood type A (genotype AO) and a parent with blood type B (genotype BO) have children with blood types A, B, a
garik1379 [7]

Answer:

Co-dominance because he expresses both of the alleles simultaneously

Explanation:

The ABO blood group system is used by humans. This blood group type is controlled by multiple alleles. Alleles A and B are both dominant over allele O but are co-dominant. Co-dominance is a type of inheritance pattern in which two alleles of a gene both express themselves i.e. neither is recessive.

This is the case of this family whose parents have a genotype of AO (blood type A) and BO (blood type B) respectively. The children have blood types A, B, and AB. However, the child with genotype AB possesses both the A and B allele, which are both expressed in his blood group (phenotype), hence, it can be said that the child is exhibiting CO-DOMINANCE for the blood group trait.
