DNA is the genetic material found in all living organisms. It is composed of four nucleotides: adenine (A), cytosine (C), guanine (G) and thymine (T). These nucleotides are the building blocks of DNA and provide the genetic code that determines the structure and function of an organism.
A nucleotide is composed of three parts: a five-carbon sugar molecule, a nitrogenous base, and a phosphate group. The five-carbon sugar molecule is the same for each nucleotide, but the nitrogenous base is different for each nucleotide. For example, adenine has a nitrogenous base of adenine, cytosine has a nitrogenous base of cytosine, and so on. The nitrogenous base is the part of the nucleotide that is used to determine one nucleotide from another.
The nitrogenous bases are classified into two groups: purines and pyrimidines. Purines are larger molecules with two nitrogenous bases, adenine and guanine, while pyrimidines contain one nitrogenous base, cytosine and thymine. Each nucleotide is unique because of the specific nitrogenous base that it contains. For example, adenine is only found with thymine, and guanine is only found with cytosine. This is known as complementary base pairing and is essential for DNA replication.

Can someone explain to me about how the pereodic table is used
Answer:
So basically the rows are called periods, and the columns are called groups. The groups show that those elements have similar characteristics. There are also different families such as the noble gases and alkali earth metals. The elements are placed where they are because of the atomic number which is directly equal to the number of protons there are. The atomic mass is the number of both protons and neutrons. Also, even though the number of protons can be equal to the number of electrons, that isn't always the case. It could be an isotope which is basically for when an element or atom isn't neutral.

In class your professor shows you an MRI scan of a primate brain. The professor points out the relatively large size of the olfactory bulb beneath the frontal lobe. This suggests to you that Group of answer choices this primate shows a derived trait for an enhanced sense of smell as this trait is not commonly observed in mammal species this is a species of prosimian because it has an increased reliance on vision this is a species of anthropoid because it has an increased reliance on vision this primate must be a species of prosimian, as that suborder of primates still relies heavily on the sense of smell for many aspects of daily life
Answer:
this primate must be a species of prosimian, as that suborder of primates still relies heavily on the sense of smell for many aspects of daily life
Explanation:
The suborder prosimian belongs to primate mammals and is at a level inferior to the real monkeys.
Prosimians characterize as having an elongated head that culminates in the snout. They have big eyes with modifications in the retina that improve sight during the night. They are quadrupeds with a svelte body and soft hair. Their tail is long but not prehensile. They move from tree to tree by making use of their extremities. They have a dental comb to clean themselves and others.
Their snout is humid, and the sense of smell is much more developed than in other primates. They are the primates with the greatest sense of smell. Their olfactory bulb and glands are remarkably developed in concern with other primates. With their tree and nocturnal habits, they depend a lot in this sense to move, relate, be aware, and feed.

Chromosomes are made of DNA.
DNA is made of chromosomes.
DNA manufactures chromosomes.
Answer:
(B) Chromosomes are made of DNA.
Explanation:
i took the test <3
Chromosomes are made of DNA which shows the relationship between a chromosome and DNA. So, the correct option is B.
What are Chromosomes?A chromosome is indeed a lengthy DNA molecule that contains all or a portion of an organism's genetic code. The very long, thin DNA fibres in most chromosomes are covered with packing proteins; in eukaryotic cells, the histones are the most significant of these proteins.
Each cell's nucleus contains chromosomes, which are structures that resemble threads and contain the DNA molecule. Each chromosome is constructed from DNA that has been tightly wound around proteins called histones numerous times to support its structure. The fact that DNA is a component of chromosomes demonstrates the connection between chromosomes and DNA.
Therefore, the correct option is B.

The brown-colored bones in each animal help to connect their limbs to a specific joint in the torso, or middle of their body. What type of structure do these bones represent, and what is their significance in terms of evolutionary relationships?
Answer: These structures connect their limbs to a specific joint in the torso or in the middle of their body. These structures can be identified as homologous, they are morphologically similar or possibly they derive from a common ancestral structure.
Explanation:
The brown color bones in animal help to connect limb homologous structures that connect their limb to the specific joint in the torso, this and having an evolutionary relationship.
What are bones?If two bones split where they meet at a joint, it is termed a dislocation. The place where two bones connect and therefore can move is called a joint.
A displaced joint is one where the bones are out of alignment with each other having a significant role in evolution.
Despite their similar arrangements and being formed in a similar way throughout embryonic development, these structures have slightly different shapes and purposes, they refer to them as homologous structures.
Therefore homologous structures have an evolutionary relationship to connect brown-colored bones connect limbs to joint torso.
