3. The mechanism in which organisms best suited for their environment survive<br> and reproduce.
lys-0071 [83]

The mechanism in which organisms best suited for their environment survive

and reproduce <u>NATURAL SELECTION.</u>

<u></u>

Explanation:

When individuals in a population compete for resources or live in their environment, the individuals with the slightest advantage over the others have an increased chance of reaching maturity and  reproducing to passing down their genes to the next generations.

Natural selection works on the variations of the population to ‘select’ the best alleles of genes in the population that offer an advantage in ‘survival for the fittest’. This how natural selection fits a population to its environment. The greater the variation within a population, the higher its capacity to adapt to changes in the environment.

A pharmacist has two vitamin-supplement powders. The first powder is 10% vitamin B1 and 30% vitamin B2. The second is 15% vitami
Basile [38]

Answer:

560 mg of powder 1 and 160 mg of powder 2

Explanation:

Let "X" denotes weight of powder 1 added to the new mixture and  "Y" denotes weight of powder 2 added to the new mixture

Total weight of vitamin B1 in the mixture is equal to 80 mg

Total weight of vitamin B2 in the mixture is equal to 200 mg

Equation 1

0.1 X + 0.15 Y= 80

Equation 2

0.3 X + 0.2 Y= 200

Let us simplify the above two equations, we will get

10 X + 15 Y = 8000\\3X + 2Y = 2000

2 (10 X + 15 Y = 8000), 20X + 30 Y = 1600015(3X + 2Y = 2000), 45X +30Y = 30000\\25 X = 14000\\X = 560

Substituting value of X in equation 2 we get

0.3 * 560 + 0.2 Y = 200\\0.2 Y = 200 - 168\\Y = 160

Which of the chains of amino acids corresponds to the nucleotide sequence AAUGGCUAC?
masha68 [24]
The correct answer is d - asparagine - glycine - tyrosine. The genetic code found in DNA is responsible for defining amino acids. It is the triplet of bases in DNA and RNA that define and direct which amino acid is used in the synthesis of a particular protein. The genetic code is expressed in 64 different triplet combinations that code for different amino acids. Of these, three triplets or codons do not code for any amino acid and are thus called non sense codons. The remaining 61 codons are called sense codons.
