Environmental factors can influence natural selection because they can increase or decrease
olchik [2.2K]

Answer:

Environmental factors can influence natural selection because they can increase or decrease the amount of genetic variation in a population.

Explanation:

Natural selection is a process that involves the survival of species through changes in the expression of their genes, making possible the process of adaptation to environmental changes. It is one of the explanations for the biological evolution of species.

The second premise, necessary for natural selection to be possible, implies the existence of a variability (genetics) of traits among individuals in a population.

The other premises of natural selection are the faculty of traits to be inheritable and that genetic variability should lead to reproductive success and survival.

  • <em>The other options are not related to the process of natural selection, since it is not possible for natural selection to increase or decrease the number of chromosomes, in addition to the fact that genetic variability must be observed in a population, not in a single individual, to be considered natural selection </em>

A mutation in a polypeptide with the original amino acid sequence of: Met-Ala-Gln-Arg-Glu-Leu results in a mutant with the seque
Nezavi [6.7K]

Answer:

This question lacks options, however, it can be answered based on general understanding of the topic

The answer is SUBSTITUTION MUTATION

Explanation:

A mutation is any change that occurs in the nucleotide sequence of a gene. Mutation can be of different types depending on how it occurs. One type of mutation is SUBSTITUTION MUTATION, which is a mutation in which one or more nucleotide base is replaced by another in the sequence.

Nucleotide bases are read in a group of three called CODON. Each of these codons specify amino acid. Hence, if the nucleotide base sequence is altered during mutation, the amino acid sequence is altered likewise. In this case where the original amino acid sequence is: Met-Ala-Gln-Arg-Glu-Leu, the mutation affected the nucleotide bases coding for Arginine (Arg), hence changing it to Glycine (Gly).

This means that a base substitution mutation occured, replacing the amino acid Arginine with Glycine in the mutated sequence.

The theory of plate tectonics:
sertanlavr [38]

A) .was immediately accepted

Explanation:

The theory of plate tectonics was immediately recognized as the explanation for the moving continents. It provided a more scientific background as why continents drift apart and the seafloor keeps spreading.

  • The theory explains that the earth is broken up into series of slabs called lithosphere which moves on the weak, ductile and fluid asthenosphere.
  • The movement of part of the earth mantle provided the mechanism through which the lithosphere moves. This is now known as the mantle convection.
  • This theory provided a scientific mechanism through which the plate moves and seafloor spreads.
  • It was immediately accepted when the theory was propounded by Alfred Holmes in the 1930s
