Answer:
plasma membrane of the target cell
Explanation:
There are two main types of acetylcholine (ACh)receptors:
- muscarinic ACh receptors (because muscarin as agonist) which are G-protein coupled receptors that initiate slow response. Mostly, they are located in the central nervous system-CNS (involved in the release of neurotransmitters), heart (control of the heart rate), smooth muscles (contraction).
- nicotinic ACh receptors (nicotin is agonist) which are ligand-gated ion channels involved in the fast response. They are located at neuromuscular junctions but also in CNS (involved in synaptic transmission between two neurons).
Answer:
Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
Explanation:
It is spelled photosynthesis not fotosintesi.
Answer:
D. cell growth
Explanation:
I learned this in the beginning of my biology class. Here is a piece from my notes.
Interphase
Interphase - the stage that will prep a cell for division
Is the stage that a cell will spend it's life in the most
G1 - immature cells will grow and mature cells will prepare to copy DNA
Growth
S - cells will copy DNA
Coping DNA
G2 - cells wait to start dividing
Answer:
C. altering blood volume
Explanation:
Systemic blood pressure has a number of controls, both nervous and hormonal in nature. Nerve control is said to be short term and is basically done by the sympathetic and parasympathetic autonomic nervous system which, as a balance, seeks to balance systemic blood pressure to values considered stable.
This type of control works through chemoreceptors, reflex arcs associated with vasomotor fibers, and reflex arcs involving baroreceptors. The goal of short-term pressure control is to maintain balance.
Answer:
CO2 and H2O are the reactant in the given formula.
Explanation:
The chemical equation that is mentioned in the question is the reaction of photosynthesis. During photosynthesis process the atmospheric CO2 reacts with H2O or water to generate glucose(C6H12O6) along with the liberation of oxygen gas(O2)
We all know that the substances those are present in the left side of a chemical or biochemical reaction are termed as reactant.
From that point of view it can be stated that in the given reaction CO2 and H2O act as reactant.
