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.

Cohesion. Cohesion is the property of water that attracts other water molecules so they can stick together. Water is sticky because it has positive and negative charge in the oxygen and hydrogen ends that attracts one water molecule to another. Adhesion is also a property of water that attracts it from other substances, making it easy for water to travel upwards through transpiration.
The answer is nonvascular plants.
The plants that are similar to algae are
called nonvascular plants. They are the plants small plants with the absence of
vascular system. They do not have roots. They have small hair likes that insert
to substrate to keep the plants in place instead of roots. These are called
rhizoids.
Answer:
Explanation:
After having a carbohydrate rich meal concentration of some hormones, especially insulin change in your body. Insulin promotes the uptake of glucose by cells(particularly muscle cells, adipocytes, liver cells). It also increases the rate of glycolysis and glycogenesis and decreases the rate of gluconeogenesis and glycogenolysis.
These important metabolic pathways cause burning up glucose to make ATP that all cells in our body need and also storing it in the form of glycogen in the liver which is a very important food storage. Metabolism of carbohydrates also causes fat to be deposited in adipocytes which is basically why we have stuff like keto diets(no or very little carbohydrates and mainly fats consumed) for losing weight!
