''A bear sharpening its claws on a tree is a good example of a bear adapting to its environment''. The given statement is false.

Explanation:

The wild bear's most noteworthy adjustment is its capacity to eat a wide range of things. Their preferred food are leafy foods, grasses, twigs, and nectar. They eat grubs, creepy crawlies, fish, and little warm blooded creatures.

Bears who discover little sustenance in their living space will come into regions where people live and will search for nourishment in junk jars or dumpsters. Dark colored bears have long, threatening claws.

These bears are inconceivably solid, ready to break the necks of numerous enormous prey with one amazing blow. Mearly, possisng the claw is not considered as adaptive feature for the bear.

Answer:

Horizontal Gene transfer

Explanation:

The phenomenon that accounts for the movement of these genes is Horizontal Gene transfer. Also known as Lateral gene transfer is the movement of genetic material between unicellular organism other than by vertical transmission of DNA from parent to offspring. Horizontal gene transfer(HGT) is very important for the evolution of organism.

What is the principle for dating materials using radioactive isotopes

nevsk [136]

It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.

<h3>How are isotopes used in radioactive dating?</h3>

These isotopes decay within the rocks according to their half-life rates, and by choosing the fit minerals and measuring the relative amounts of parent and daughter isotopes in them, the date at which the rock crystallized can be determined.

Thus, It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope.

Can you guys help me out with some honors bio questions I have? I will give brainliest thanks in advance!!

Answer:

1. When using a codon chart, the mRNA sequence (option B) is used to determine the amino acid .

2. The amino acid that is represented by the UUA codon is leucine (Option A).

Explanation:

Messenger RNA (mRNA) is the molecule that contains the genetic code that must be translated by the ribosome for protein synthesis to be possible.

The nitrogenous bases in mRNA are adenine, guanine, uracil and cytosine, which form specific sequences in the molecule. The sequence of bases in the MRA can be organized into triplets of bases, called codons, which code for:

Initiation of protein synthesis.
Number and position of amino acids in the protein.
The stop of protein synthesis.

From this information it can be stated that the mRNA contains the sequence used to synthesize amino acids and UUA codon codes for the amino acid leucine (Leu).

The other options are not correct because:

1. A) DNA contains the genetic information, and its molecule must be transcribed into mRNA to be translated into amino acids.

C) tRNA is in charge of conducting the amino acids to the ribosome during protein synthesis, matching its anticodon to the mRNA codon.

2. UUA does not code for:

B) Serine, which is coded by UCU, UCA, UCG and UCC.

C) STOP. The three STOP codons are UAA, UAG and UGA.
