A student attaches a rope to the handle of a chest loaded with few books , books while the other end of the rope is tied to a sc

ale. The student pulls the scale with just enough force to set the chest in motion and records the force applied on the spring scale. The student repeats the experiment with more books in the chest and records the data in a table.

Answer:

B. As the mass of the chest increases, more force is required to pull it.

Explanation:

Option B is the correct that can be concluded from the data.

From the data, we can see that the mass of the chest is on the increase; it increases from 50, 75, 100, 150 and to 175. Also, in the force column, we can see an increment in the force also; from 0.25, 0.50, 1.15, 1.50 and to 1.70. So, from this data, we discover that as the mass increases, the force needed to pull it increases also.  

Moreover, this is true even logically. If you want to pull an object with a heavy, more force will be required to pull it. Therefore, Option B is the correct answer.

A certain eukaryotic organism has multiple, distinct genes with highly similar sequences that are expressed at different times i

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.
