The theory of endosymbiosis and the history of life on earth allows one to predict that the gene sequences that are responsible for encoding functional, mitochondrial ribosomes in a particular tree likely share many similar nucleotides in the sequences from the ribosomal genes of other bacterial species (Option II).

The theory of endosymbiosis is a model to explain the origin of eukaryotic cells, which postulates that these types of organisms evolved as a consequence of symbiotic relationships between primitive bacterial cells that converted into mitochondria and chloroplasts in animals and plants.

Therefore, with this data, we can see that the theory of endosymbiosis is based on the scientific idea that eukaryotic cells as observed in plants and animals generated due to symbiosis with primitive bacterial cells that entered into the cell and performed cellular respiration and photosynthesis.

What is equational division?

Chromosome replication and equal distribution between the two daughter cells occur during the cell division process known as mitosis. Each daughter cell has the same number of chromosomes as the parent cell, making them diploid. Thus, mitosis is also referred to as equational division.

Unequal division will result if the cell didn't replicate prior to actually cell division. As a result of the checkpoints, it won't move on to the next step. The checkpoint will later start the apoptosis process, which results in programmed cell death.

Initiation, elongation, and termination are the three steps of transcription that are depicted here. Initiation, elongation, and termination are the three stages of transcription.

The process of copying DNA to create a complementary strand of RNA is called transcription. After that, RNA is translated to become proteins. Initiation, promoter removal, elongation, and termination are the four main phases of transcription.

Transcription takes place in the cell's nucleus since the genes are bound there, but the mRNA transcript needs to be delivered to the cytoplasm. In prokaryotes, which include bacteria and archaea, transcription takes place in the cytoplasm of the cell since these organisms lack organelles and membrane-bound nuclei.

Multipolar neurons are the ones that have a single axon and several dendrites.

These neurons are usually located in the central nervous system and integrate information coming from other nerve cells.

Every neuron forms connections with other neurons. These connections are known as synapsis.

As it happens in every synapsis between neurons when a presynaptic neuron sends information, a neurotransmitter is released.

Neurotransmitters are chemical substances that travel through the synaptic cleft to the junctional area of the other neuron and bind to its receptors in the postsynaptic membrane.

This binding produces a depolarization of the cell called an excitatory postsynaptic potential.

A beneficial mutation is one that has a good effect on an organism. These mutations are uncommon yet important. The benefit that a beneficial mutation provides the organism is passed down from generation to generation, increasing the chances of survival for the offspring.

Neutral mutations:

Neutral mutations are changes in DNA sequence that are neither beneficial nor harmful to an organism's ability to survive and reproduce. In population genetics, neutral mutations are mutations in which natural selection has no effect on the spread of the mutation in a species.

Harmful mutations: Mutations that are harmful can result in genetic diseases or cancer. A genetic condition is an illness that results from a mutation in one or more genes. Cystic fibrosis is a human example. A single gene mutation causes the body to produce thick, sticky mucus, which clogs the lungs and blocks ducts in digestive organs.
