These genes could have arisen by gene duplication.

<h3>What is gene duplication?</h3>

Gene duplication is the process of copying a section of DNA that codes for a gene. A retro transposition event or a recombination mistake are both potential causes of gene duplication. As a result, the duplicate gene coding may experience a significant number of modifications throughout time. This might prevent the gene from functioning or, in other situations, give the creature a benefit.

Gene duplication is a phenomenon that can happen through a variety of ways:

  • Ectopic Recombination: Uneven crossing-over between misaligned homologous chromosomes during meiosis might result in duplications. A duplication at the exchange site and a reciprocal deletion are the results of this recombination.
  • Replication Slippage: Short genomic sequences can be duplicated as a result of the replication error known as replication slippage. DNA polymerase starts copying the DNA during replication, but eventually the polymerase separates from the DNA, causing replication to stall. The replicating strand is incorrectly aligned when the polymerase reattaches to the DNA strand, which accidentally results in several copies of the same portion.
  • Aneuploidy: When a single chromosome's nondisjunction causes an abnormally high number of chromosomes, this condition is known as aneuploidy. Aneuploidy is frequently damaging and frequently causes spontaneous miscarriages in mammals. Some aneuploid people can survive. For instance, human trisomy 21 causes Down syndrome but is not lethal.

Answer:

The correct option is A

Explanation:

To determine if water temperature has an effect on weathering of sedimentary rocks, different number (perhaps three) of identical sedimentary rocks should be obtained and then individually placed in different water temperatures (with at least one of the "water volumes" used for each having a temperature close to the room temperature so as to be used as the control).

Thus, each of the identical sedimentary rock can be broken into three and placed individually; as in one part of the rock in 20 °C of water (control), another part of the rock in 40 °C and another in 60 °C of water.

This above procedure should be repeated for the remaining two other identical sedimentary rock to confirm if there is any effect.

Sunny_sXe [5.5K]

A special group of chemical substances that are used to treat diseases caused by microbes are called antibiotics.

An antibiotic is a chemical compound that is toxic to other bacteria and is produced by a living thing, usually a bacterium. In a complex environment like soil, organisms undoubtedly use antibiotics to regulate the growth of competing microbes. Soil microorganisms frequently produce antibiotics.

Bacteria and fungi are microorganisms that produce antibiotics that help prevent or treat disease. With the invention of penicillin in 1941, antibiotics gained widespread recognition. Since then, they have fundamentally changed how bacterial infections in humans and other animals are treated.
