One way in which the DNA structures of prokaryotic and eukaryotic cells are similar is that both have sugar-phosphate backbones.
The DNAs of all living organisms, be it prokaryotes or eukaryotes, are similar and consists of 3 major chemical groups:
5-carbon deoxyribose sugarsnitrogenous purine or pyrimidine basesphosphate groupThe pentose deoxyribose sugar and the phosphate group form the backbone of the structure of DNA. The sugars are linked together by phosphodiester bonds formed between the carbon 4 of each sugar and the methyl group attached to the phosphate.
The similarity in the structure of DNA of all living organisms is one evidence being used to support the evolution of living organisms from a common ancestor.

Answer:
Covalent bond
Explanation:
The answer is covalent bond
A molecule of octane which is a component of gasoline contains covalent bonds.
Octane is a hydrocarbon compound, specifically an alkane, with the molecular formula C8H18. The structure you've provided illustrates the arrangement of carbon (C) and hydrogen (H) atoms in octane.
In octane, each carbon atom forms four single covalent bonds with other atoms (either carbon or hydrogen). Covalent bonds are formed when atoms share electrons to achieve a stable electron configuration. In the case of octane, carbon atoms share electrons with other carbon and hydrogen atoms to fill their valence electron shells, resulting in a stable and energetically favorable arrangement.
The structure of octane is a straight-chain alkane, with carbon atoms forming a chain and hydrogen atoms attached to the carbon atoms. The single covalent bonds between the atoms are represented by lines in the structural formula.
The shape of the molecule is determined by the arrangement of atoms and the types of bonds between them. In the case of octane, the single covalent bonds allow the carbon atoms to form a linear chain.
In conclusion, octane molecules are held together by covalent bonds, specifically single covalent bonds between carbon and hydrogen atoms. This type of bonding contributes to the stability and structure of the octane molecule, making it a major component of gasoline and contributing to its combustible properties.

Answer:
Four haploid cells.
Explanation:
These reproductive cells are produced through a type of cell division called meiosis. During meiosis, a diploid parent cell, which has two copies of each chromosome, undergoes one round of DNA replication followed by two separate cycles of nuclear division to produce four haploid cells.

what is metaphase and what does it do?
Answer:
Metaphase is the second stage of cell division, between prophase and anaphase, during which the chromosomes become attached to spindle fibers. A metaphase separates duplicated genetic material that is carried in the nucleus of a parent cell and then converts it into two identical daughter cells.
Answer:
Metaphase is a stage in the cell cycle where all the genetic material is condensing into chromosomes. These chromosomes then become visible. During this stage, the nucleus disappears and the chromosomes appear in the cytoplasm of the cell. As metaphase continues, the cells partition into the two daughter cells.

which part of electromagnetic spectrum drives the photosynthetic process in plants?
Answer:
visible ligth
Explanation:
Visible light ranges from low blue to far-red light and is described as the wavelengths between 380 nm and 750 nm, although this varies between individuals. The region between 400 nm and 700 nm is what plants use to drive photosynthesis and is typically referred to as Photosynthetically Active Radiation (PAR).

in terms of structure, how do channel proteins differ from carrier proteins?
Answer:
Moreover, carrier proteins can carry out both active and passive transportation of solutes, whereas channel proteins bring about passive transport only. Both carrier proteins and channels proteins also differ in their chemical composition - whilst the former are glycoproteins, the latter are lipoproteins.
Explanation:
hope this helped you if it did please mark brainiest
Carrier proteins can carry out both active and passive transportation of solutes, whereas channel proteins bring about passive transport only.
What are the functions of carrier proteins?Carrier protein is a type of cell membrane protein involved in facilitated diffusion and active transport of substances out of or into the cell. Carrier proteins are responsible for the diffusion of sugars, amino acids, and nucleosides.
Moreover, carrier proteins bind specific solutes and transfer them across the lipid bilayer by undergoing conformational changes that expose the solute-binding site sequentially on one side of the membrane and then on the other.
Membrane carrier proteins are important transmembrane polypeptide molecules which facilitate the movement of charged and polar molecules and ions across the lipid bilayer structure of the cell membranes.

Answer:
Organ system
Explanation:

The organization level of the body involves simple and complex arrangements. The level of the brain in the body can be described by organ. Thus, option b is correct.
What is the level of organization?The arrangement of the various structures based on their complexity to form a whole organism and biosphere is called the level of organization. It starts with chemicals that make atoms and molecules.
The molecular aggregate makes the cells that bind together to form a tissue. The structurally similar tissues make the organ. The nerve, endothelial, and glial cells make the tissue of the brain.
The brain is an organ that together with the spinal cord makes the organ system called the central nervous system, or CNS. This organ system together with others makes the organism.
