option-A if there is a change in the oxidation states of atoms from reactants to products, the reaction in an oxidation reduction reaction describes the oxidation-reduction .
We know that oxidation is a process that increases the oxidation number, whereas reduction is a process that decreases the oxidation number. An oxidation-reduction (redox) is a type of chemical reaction wherein the electrons are exchanged among distinct strains Any chain reaction that occurs when the oxidation number of the a molecule, atom, or ion modifications by acquiring or losing an electron is an oxidation-reduction reaction. Reduction-oxidation reaction any chemical reaction in which one species oxidizes (loses electrons) while another species reduces (gains electrons) Oxidized. defines an element that has lost electrons and increased its oxidation number

the complete question is:
Which best describes oxidation-reduction reactions?
A- if there is a change in the oxidation states of atoms from reactants to products, the reaction in an oxidation reduction reaction
B-If there is formation of salt and water, the reaction is an oxidation-reduction reaction.
C-If there is formation of a precipitate, the reaction is an oxidation-reduction reaction.
D-If there is no change in the oxidation states of atoms from reactants to products, the reaction is an oxidation-reduction reaction.
Answer:
They are similar because they both produce energy but in two different forms.
Photosynthesis- It produces oxygen and G3P, simple carbohydrate molecules that are high in energy and can be converted into glucose, sucrose, or other sugar molecules.
cellular respiration-During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water.
Answer:
pituitary gland-growth hormone
thyroid gland- thyroxine
adrenal gland- adrenalin
pancrease- insulin
ovary-estrogen
testis-testosterone
Explanation:
Answer:
Nyctophobia
Explanation:
Nyctophobia is known as the fear of darkness
Answer:
The correct answer will be- primary motor cortex
Explanation:
The motor cortex is the portion of the brain present in the precentral gyrus of the frontal lobe of the brain. The motor cortex is thought to be involved in the planning actions and control voluntary actions.
The motor cortex is divided into three regions: premotor cortex, primary motor cortex and supplementary motor area.
The primary motor cortex is the region of the motor cortex which controls the voluntary movements in the human body by generating the impulse.
Thus, the primary motor cortex is the correct answer.
