Answer:

Chromosomes were first named by cytologists viewing dividing cells through a microscope. The modern definition of a chromosome now includes the function of heredity and the chemical composition. A chromosome is a DNA molecule that carries all or part of the hereditary information of an organism. In eukaryotic cells, the DNA is packaged with proteins in the nucleus, and varies in structure and appearance at different parts of the cell cycle.

Explanation:

Cells reproduce genetically identical copies of themselves by cycles of cell growth and division. The cell cycle diagram on the left shows that a cell division cycle consists of 4 stages:

G1 is the period after cell division, and before the start of DNA replication. Cells grow and monitor their environment to determine whether they should initiate another round of cell division.

S is the period of DNA synthesis, where cells replicate their chromosomes.

G2 is the period between the end of DNA replication and the start of cell division. Cells check to make sure DNA replication has successfully completed, and make any necessary repairs.

M is the actual period of cell division, consisting of prophase, metaphase, anaphase, telophase, and cytokinesis.

Rudik [331]

According to the given statement:

The amino acids in fish protein must be released in hydrolyzed and integrated into other polypeptides in dehydration reactions, according to the declaration.

<h3>What exactly is a dehydration reaction?</h3>

A dehydration reaction is a reaction in which water is lost from the responding molecule or ion. Dehydration reactions, the inverse of hydration reactions, are common processes.

<h3>What is a typical hydrolysis reaction?</h3>

A hydrolysis reaction is the dissolution of a salt of a sluggish acid or base in water. Strong acids can be hydrolyzed as well. When sulfuric acid is dissolved in water, it produces hydronium and produces high.

Why are archaea in a different domain from bacteria apex?

mariarad [96]

The archaea are in a different domain from bacteria due to certain differences in their morphology and habitats, the Archaea are the separate domain of life in prokaryotes. For example; unlike bacteria, archaea cell walls do not contain peptidoglycan, they have different membrane lipid bonding from bacteria and eukarya.
Archaea is considered as the different domain of life in prokaryotes, as they are the most primitive type and known as the ancient microbes found in extreme niches such as hydrothermal vents, higher salt concentration, high temperature, and pressure etc

olchik [2.2K]

Answer:

Animal ; prokaryote ; plant ; virus

Explanation:

Animal: An animal cell possesses cell membrane, ribosomes, lysosomes and nuclear membrane.

Prokaryote: In a prokaryotic cell, cell wall is present such as bacteria, ribosomes are present but nuclear membrane is absent

Plant: A plant cell possesses cell wall, ribosomes, nucleus and a large vacuole.

Virus: Viruses reproduces inside a cell because they do not have their own energy producing system, nucleus is absent but nucleic acid ( DNA or RNA) is present
