Answer: the answer is (d)
Explanation:
For a chemical reaction to occur, activation energy is required. Using the activation energy, reactants form products by breaking bonds which require energy. This type of reaction is an endothermic reaction. When products are formed, bonds are formed back by releasing energy. This type of reaction is an exothermic reaction. When activation energy is used for a reaction, a catalyst is not required. Adding a catalyst to the reaction causes the rate of reaction to increase.
A lion and a leopard have almost the same characteristics in terms of feeding habitat and behavior. because the lion rules the wild. The lion is the forest's king, and he is feared by every animal that lives there. Additionally, lions hunt other large or small animals in packs.
Leopards and lions differ significantly in terms of their physical characteristics, size, and socialization. The majority of lion species have manes, and they are exceptionally huge quadrupedal cats that live in groups called prides. Leopards lack manes, are more solitary than lions, have spotted fur, and are smaller than lions.
The hybrid offspring of a male leopard and a female lion is known as a leopon. The animal resembles lions in the head, whereas leopards are more likened to in the rest of the body. These hybrids are created in facilities; they are not expected to appear naturally. The Leopard's greatest foe is undoubtedly the Lion, with whom it will engage in a fight to the death. Leopards, especially the young cubs, have been known to be attacked and killed by baboons and hyenas.

Base substitutions, deletions, and insertions are the three different forms of DNA mutations.
A mutation is a long-lasting alteration to the DNA's nucleotide sequence that can occur during replication and/or recombination. Damaged DNA can change by base pair replacement, deletion, or insertion. The majority of the time, mutations are benign, unless they result in tumor growth or cell death. Cells have developed systems for repairing damaged DNA due to the deadly potential of DNA mutations.
Different Mutations
Base substitutions, deletions, and insertions are the three different forms of DNA mutations.
1. Base Replacements
Point mutations are single nucleotide replacements; you may recall the point mutation Glu ——-> Val is the culprit of sickle cell anemia. There are two types of point mutations, the most prevalent of which are.
Transition and Transversion.
