Archaebacteria look much alike organisms from what other kingdom due to their similar shapes?.

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.

Phylogenetic order from the largest most inclusive group to the smallest and most exclusive group: Protostomes > Ecdysozoa > Arthropods > Insects.

Phylogeny is a classification description that shows the kinship relationship of a species with its ancestors and the evolutionary relationship between organisms.

Protostomes are divided into two groups:

Arthropods are triploblastic protostomes. They also have a nervous system with a dorsal "brain", an oropharyngeal nerve, and a pair of ventral nerves. Like annelids, their bodies are segmented both internally and externally. This is taken as evidence that annelids and arthropods are closely related. We now believe that segmentation is a convergent property.

Insects are the most successful group of organisms on the planet. Every third species of organism is an insect. During its development, the insect acquires several features that contribute to its success. The earliest insects lacked wings: The evolution of insect wings was a milestone - the first creatures to soar into the sky ruled the skies for 100 million years.

Answer:

Parathyroid hormone regulates calcium levels in the blood, largely by increasing the levels when they are too low. It does this through its actions on the kidneys, bones and intestine: Bones – parathyroid hormone stimulates the release of calcium from large calcium stores in the bones into the bloodstream.

The hormone that aids in regulating intestinal calcium and phosphorus absorption is Adrenal glucocorticoids. The correct option is a.

The adrenal cortex creates steroid hormones known as glucocorticoids. They have pleiotropic actions and significantly support the preservation of homeostasis at rest and in response to stress.

By increasing or lowering protein metabolism, adrenal glucocorticoids assist in controlling intestinal calcium and phosphorus absorption.

Your adrenal glands create the glucocorticoid hormone cortisol, which is then released into the body. Hormones are substances that communicate with your organs, skin, muscles, and other tissues through your blood to coordinate various bodily functions. These signals advise your body on what to do and when.

Homoplasy in biological systematics is when a trait has been gained or lost independently in separate lineages during evolution.

What is Homoplasy?

A shared trait between two or more animals that did not develop from a common ancestor is known as homoplasy. The opposite of a homology, in which two or more creatures share a common origin and the genes that gave rise to the trait, is a homoplasy. When two very distinct animal groups evolve to do the same activity, it is known as homoplasy. This is referred to as convergence or convergent evolution. An analogous characteristic is another name for a homoplasy trait. Examining some examples is the most effective technique to grasp what constitutes and does not constitute a homoplasy.

The characteristic of wings makes homoplasy the simplest to comprehend. Although wings have developed in many different forms and materials throughout the animal kingdom, flight remains their primary purpose. Wings have evolved in a variety of insects, birds, and bats. Every time, the feature developed apart from the other groups. Without a doubt, the closest living relative of birds, bats, and insects lacked wings. All lineages developed flight as a result of a comparable pressure that resulted from the lineages' diverging, or moving in different directions.

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.

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.
