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.

The correct option to this question will be 'C' i.e., Gorilla Gorilla.
As the number of Differences of the amino acids representing for the beta-haemoglobin is less than other 5 species from humans, so we can say that Gorilla is closely related on the basis of molecular data given in the question. The beta Haemoglobin Gene is responsible for coding a protein which is called beta-globin. Each cell present in humans contains two genes of beta-globin.
Answer:
healthy diet prevents and protects from diseases like obesity, heart disease, diabetes, cancer and stroke. constantly eating junk food can lead to obesity and chronic diseases like cardiovascular disease, type 2 diabetes, non-alcoholic fatty liver disease and some cancers.
Explanation:
The correct answer is the one that shows a bone having the most porous appearance inside.
Osteoporosis is a disease of the different types of bone tissue that make up bone ("cortical bone" and "trabecular bone").
It is a disease that is related to a decrease in the amount of bone tissue in the bones and / or an alteration of its structure: thinning of the cortex and bone trabeculae that become porous.
The cause is an imbalance between the deficit activity of osteoblasts and normal osteoclastic bone resorption.
Answer:
Bioarchaeology is a discipline that studies human skeletal remains in an archaeological investigation; while forensic anthropology refers to the study of human skeletal remains in a criminal case
Explanation:
Bioarchaeology is a discipline centered on the study of skeletal remains in order to obtain useful information about past societies/civilizations such as, for example, health conditions. On the other hand, forensic anthropology investigates human skeletal remains within a legal and/or criminal investigation. This information may result useful to identify a dead person, find the cause of death, and estimate time since death.
Similarities:
-Both disciplines have a strong biology background (especially in zoology)
-Both disciplines are focused on skeletal analysis
Differences:
-Bioarchaeology is associated with the anthropological study of human societies, while forensic anthropology associated with legal investigations
