Answer: N. pubens has found a place within the existing food web in its new environment.

Explanation:

The statement that best explains the impact that N. pubens has on its environment is that "N. pubens has found a place within the existing food web in its new environment".

From the information given, it's stated that the Rasberry crazy ant (Nylanderia pubens) was accidentally introduced in Texas and it attacks livestock, displace existing species, and damage electrical equipment.

It's further stated that it consumes "honeydew," a sugary liquid substance secreted as a waste product by aphids, which suck the sap out of plants.

This shows that it has found a place within the existing food web in its new environment.

Several organisms have a homologous protein (inherited from a common ancestor) that is highly similar at the amino acid level. Y
8_murik_8 [283]

Answer:

The correct answer is: C. third nucleotide position.

Explanation:

  • Genes located on the chromosomes encodes for proteins.
  • A Gene is made up of a  Deoxyribonucleotide (DNA) sequence which is transcribed into the messenger Ribonucleotide (mRNA) sequence by the help of RNA polymerase.
  • This mRNA sequence is further translated into the amino acid sequence, that folds to form the functional protein, by the help of the Ribosome.
  • The Ribosome reads the mRNA sequence in the form of triplets (three nucleotide together) and each such triplet nucleotide codes for an amino acid.
  • Each such triplet nucleotide is known as a Codon.
  • The Genetic Code is a table which represents the  amino acid encoded by each codon.
  • However, the Genetic Code is degenerate in nature. This means that one amino acid can be coded by more than one codon.
  • This is because, among the the three nucleotide positions in a codon only the first two determine the specificity of the amino acid while the third nucleotide, also called the wobble nucleotide, is not specific. Presence of any nucleotide in the third position of the codon will not alter the amino acid encoded by the codon.
  • In the given question, organisms producing homologous protein have similar amino acid sequence but they vary in the corresponding nucleotide sequence of the gene which codes for the homologous protein.
  • This is because at the nucleotide level the variation lies in the wobble nucleotide position that occupies the third position in the codon.

Goryan [66]

The bulldog ant has a diploid number of two chromosomes. Therefore, following meiosis, each daughter cell will have a single chromosome. In addition to mutations, genetic diversity might be generated in this species due to (C) crossing over and random fertilization.

There are some points during sexual reproduction which might increase the chances of a genetic diversity.

During meiosis I, crossing over during prophase produces sets of chromosomes having new combinations of alleles.

Genetic diversity might also generated by random fertilization of the gametes created through meiosis. Any of the genetically distinctive sperm produced by a male might fertilize the genetically distinctive egg produced by a female.

How do enzymes act as catalysts to help maintain homeostasis for the cell.
Alenkasestr [34]
Enzymes are the things in our bodies that facilitates reactions.  They break down bonds in carbohydrates, lipids and proteins.  When the food is being broken down, it is easier for the body to use.  When the body is conducting cellular respiration, it uses monosaccharides (singular carbohydrate), to form ATP which is useable energy for the body.  The body uses ATP everywhere for all bodily functions, which maintains homeostasis. <span />
