The sympathetic nervous system releases hormones known as catecholamines which increase the heart rate.
<h3>What is a heart rate? </h3>
it is the number of contractions of the heart per minute.
<h3>What are catecholamines?</h3>
These are the neurotransmitters that have a catechol and a side chain that is an amine.
<h3>Which catecholamines are released by the sympathetic nervous system?</h3>
Epinephrine and norepinephrine are the catecholamines that are released by the sympathetic nervous system to increase the heart rate.
<h3>Where are these hormones released?</h3>
These hormones are released in the blood.
<h3>How does this hormone increase the heart rate?</h3>
- "These hormones are released at the neuromuscular junction of the cardiac nerves."
- "They shorten the repolarization period."
- This speeds up the rate of depolarization and contraction and thus the heart rate is increased.

Since simple sugars follow the Cn(H2O)n formula, if you had 11 oxygen
atoms, this would produce the simple sugar formula of C11H22O11.
Therefore, there should be 22 hydrogen atoms.
Answer:
(b) - False
Explanation:
Prochlorophyte bacteria are photosynthesizers and have the same chlorophyll found in algae and vegetables, studies claim that these bacteria are the most abundant beings on the planet, accounting for half of all photosynthesis performed in the oceans.
Prochlorophyte bacteria can be divided into <em>Prochloron</em>, <em>Prochlotrix</em> and <em>Prochlorococcus</em> genera.
However, <u>prochlorobacteria</u> are not responsible for the production of dairy products, in which the most associated bacterial genera are <em>Lactobacillus</em> and <em>Streptococcus</em>. This last statement implies that alternative b is the correct one.

Answer:
Signal transduction is what allows cells to respond to the influences of the environment around them, providing cells with proper growth and normal cell function.
Explanation:
Living organisms have developed a wide variety of complex processes to transmit signals from the outside to the inside to elicit an adequate cellular response. Defects in these molecular pathways can lead to very different disorders, such as diabetes, cancer, and psychotic illnesses. Signal transduction is the process by which a cell converts a certain signal or external stimulus into another signal or specific response, that is, it is the mechanism by which a cell responds to the stimuli it receives from the environment through diffusion. of those signals to its internal compartments. First, a signaling molecule (also called a ligand) needs to activate a specific receptor on the cell's membrane or cytoplasm. Ligand-receptor binding is very specific; they are recognized as a key and a lock. Second messengers are molecules that allow the received signal to be amplified at the intracellular level. The binding of a ligand to the receptor can generate hundreds of second messenger molecules that, in turn, can modify thousands of effector molecules and give rise to different responses. Cells recognize, integrate, and respond to multiple signals from their environment due to signal transduction, providing cells with a normal cell function.
