What is difference between acid and bases?
Definition. A substance, mostly liquid that donates a proton or accepts an electron pair in reactions. An acid increases the concentration of H+ ions. A base is a substance that releases hydroxide (OH-) ions in aqueous solution, donates electrons and accepts protons.
(just if someone needs this i guess)
Answer:
Acids are sour, gives burning sensation, generally sticky, reacts with metals to produce hydrogen gas. Although bases are opposite as they are bitter, generally odorless (except ammonia), they are slippery; bases react with fats and oils. In phenolphthalein, indicator acids remain colorless, and base gives pink color.

What are the 4 nitrogen bases in a DNA nucleotide, and how to they pair together?
Answer:
Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guani

Explanation:
True or false, Water contains half as many hydrogen atoms as oxygen atoms.
Answer:true
Water is made up of 2 atoms of hydrogens and 1 atom of oxygen to form a molecule. Water contains half as many hydrogen atoms as oxygen atoms. Water is a polar molecule which means it has slightly charged ends. ... This means it bonds to like molecules and ionic molecules.
Explanation:
Stoichiometry must be multiplied by the number that is printed on the element's foot in order to determine how many atoms of a certain element there are in a given molecule. Therefore, the given statement is false.
What is atom?The smallest component of any element, molecule, or compound is called an atom. Atoms have a central nucleus and electrons that move in a set orbit around it.
In the nucleus, proton and neutron are present. Electron has -1 charge while proton has +1 charge. Neutron is neutral that is it has no charge. Overall, only the proton—not the neutron—is responsible for the nucleus' charge.
Two hydrogen atoms and one oxygen atom combine to produce the molecule of water. Hydrogen atoms make up 50% of the oxygen atoms in water.
Therefore, the given statement is false.

Which of the following statements tells how facilitated diffusion differs from
simple diffusion?
A. Particles move through cell membranes without the use of energy by cells.
B. Particles tend to move from high concentration to lower concentration.
C. Particles move within channel proteins that pass through cell membranes.
D. Particles tend to move more slowly than they would be expected to move.
Answer:
I think its C but I am not sure, I hope this helps :)
Explanation:
The statement 'particles move within channel proteins that pass through cell membranes' indicates the reason for which facilitated diffusion differs from simple diffusion (Option C).
Diffusion (both facilitated diffusion and simple diffusion) refers to the movement of substances across biological membranes from an area of high concentration to an area of low concentration.
Facilitated diffusion and simple diffusion are two types of passive transport that do not require energy to move molecules/ions in favor of a concentration gradient.
In facilitated diffusion, specific membrane proteins known as carriers or channels help to the movement of substances in favor of a concentration gradient.
Conversely, in simple diffusion, small molecules (e.g. CO2 and oxygen) freely diffuse across a selectively permeable membrane in favor of a concentration gradient.
In conclusion, the statement 'particles move within channel proteins that pass through cell membranes' indicates the reason for which facilitated diffusion differs from simple diffusion (Option C).

Describe the following types of cell signaling:
Autocrine:
Juxtacrine:
Endocrine:
Paracrine:
Answer:
Autocrine:Autocrine signaling means the production and secretion of an extracellular mediator by a cell followed by the binding of that mediator to receptors on the same cell to initiate signal transduction. A well-characterized form of autocrine signaling is the secretion of IL-1 by macrophages.
Juxtacrine:In biology, juxtacrine signalling (or contact-dependent signalling) is a type of cell–cell or cell–extracellular matrix signalling in multicellular organisms that requires close contact. ... A membrane ligand (protein, oligosaccharide, lipid) and a membrane protein of two adjacent cells interact.
Endocrine:The endocrine system is the collection of glands that produce hormones that regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep, and mood, among other things.
Paracrine:Paracrine signaling is a form of cell signaling or cell-to-cell communication in which a cell produces a signal to induce changes in nearby cells, altering the behaviour of those cells. ... However, the exact distance that paracrine factors can travel is not certain.

Why are epithelial cells in membranes
packed tightly?
to keep organs connected
to protect organs
to form different layers
Answer:
to protect organs
Explanation:
Epithelial cells are cells found in the human skin. They are tightly packed cells which helps to protect organs in the human body.
The cells are divided into different layers with an inner part and the outermost layer.
The skin is the largest organ of the human body. It protects all organs from the external environment.
