Explain the importance of gene regulation in prokaryotic cells.
-Explain the importance of gene regulation in eukaryotic cells.
Answer:
Prokaryotic cells can only regulate gene expression by controlling the amount of transcription. As eukaryotic cells evolved, the complexity of the control of gene expression increased. For example, with the evolution of eukaryotic cells came compartmentalization of important cellular components and cellular processes.

How does an atom become a positive ion?
O A. It loses an electron.
O B. It gains a neutron.
O C. It gains an electron.
D. It loses a neutron.
Answer:
The answer is C
Explanation:
Mark the brainly
Answer:
A. It loses an electron
Explanation:
An atom becomes a positive ion when it loses an electron (then there are more protons than electrons in the atom) when it is trying to reach stability. This is called a Cation. The opposite of this is an Anion, when an atom gains an electron to reach stability and becomes a negative ion (because the number of electrons are higher than the number of protons).

A student placed 20 ml of different sweet drinks in seven identical flasks She then added 5 grams of yeast to each flask Each flask was then covered with identical balloons as shown below
Balloon size increases as the sugar increases in the solution.
As the yeast feeds on the sugar or sugar solution which produces carbon dioxide gas. Due to presence of balloon, there is no place to go so gas slowly fills the balloon. Carbon dioxide gas produces from yeast fills thousands of balloon.
That solution which have high amount of sugar in it will leads to higher concentration of carbondioxide gas in the balloon so we can conclude that balloon size increases as the sugar solution increases.

Glucose molecules bond together in a process known as dehydration synthesis. What
happens in this process?
The reaction uses water molecules to break the bonds in each glucose.
O4 water molecules are lost from each bond broken
O 4 Water molecules are used for every
O 1 water molecule is lost (OH + H) for every bond formed
Glucose molecules bond together in a process known as dehydration synthesis, and in this process, 1 water molecule is lost (OH + H) for every bond formed. The last option is correcting the glucose dehydration reaction.
What is glucose dehydration?The macromolecules, such as the polysaccharides and proteins, are formed by the dehydration reaction, and in this reaction, the water is lost to make the polymer. The single glucose molecules unite with each other and release a single unit of water to form the polymers, and in this way the polymers such as glycogen, starch, and cellulose are formed.
In the case of proteins, each amino acid dehydrates and releases one molecule of water, forming the polypeptide chain. As a result of the dehydration process, the monomers combine to form the polymer, which can be structural or functional.
Hence, for every bond formed, one water molecule (OH+H) is lost. The last option is correct regarding the glucose dehydration reaction.

neutron
proton
(PLEASE HELP IF U CAN , 50 POINTS : NEED IT BY 11:59)
Answer:
Atomic Models Of Elements: Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). ... Atoms are made up of protons and neutrons located within the nucleus, with electrons in orbitals surrounding the nucleus.
Lithium:Lithium is a chemical element with the symbol Li and atomic number 3. It is a soft, silvery-white alkali metal. Under standard conditions, it is the lightest metal and the lightest solid element. because it is present in trace amounts in virtually all rocks.
Florine:Fluorine is a chemical element with the symbol F and atomic number 9. It is the lightest halogen and exists at standard conditions as a highly toxic, pale yellow diatomic gas. As the most electronegative element, it is extremely reactive, as it reacts with all other elements, except for argon, neon, and helium.
Electron:Electron is a free and open-source software framework developed and maintained by GitHub. It allows for the development of desktop GUI applications using web technologies: it combines the Chromium rendering engine and the Node.js runtime.
Neutron:The neutron is a subatomic particle, symbol n or n⁰ , which has a neutral charge, and a mass slightly greater than that of a proton. Protons and neutrons constitute the nuclei of atoms.
Proton:A proton is a subatomic particle, symbol p or p⁺ , with a positive electric charge of +1e elementary charge and a mass slightly less than that of a neutron. Protons and neutrons, each with masses of approximately one atomic mass unit, are jointly referred to as "nucleons".
