Answer:
1.
•After the left ventricle contracts, the aortic valve closes and the mitral valve opens, to allow blood to flow from the left atrium into the left ventricle.
•As the left atrium contracts, more blood flows into the left ventricle.
•When the left ventricle contracts again, the mitral valve closes and the aortic valve opens, so blood flows into the aorta.
2.
•Diffusion is defined as the movement of individual molecules of a substance through a semipermeable barrier from an area of higher concentration to an area of lower concentration.
Explanation:
Dinoflagellates are a type of algae that live in a symbiotic relationship with the coral. The algae are autotrophic, meaning they can convert the energy of the sun into chemical energy that organisms can use. The algae share some of the nutrients they produce with the coral in exchange for coral's protection.
if the algae die off, the coral loses an important source of nutrients and dies too.
The ATP is then used throughout the cell and through the body for all of its needs. Carbon atom starts out in photosynthesis as part of a carbon dioxide molecule. Carbon dioxide is broken down into oxygen and carbon.
Answer:
The correct answer is option a.
Explanation:
Sanschool will prevent potassium channels and are utilized as analgesic, as the normal resting membrane potential is going to get upsurged, that is, from -70mV to -25mV. Due to the inhibition of the K+ channels, it will eventually stimulate the action potential to generate the false sensation of pain, that is, proprioception. This sensation will travel to the brain because of the exciting sensory neurons, in the meantime activation of TRPV1 and TRPA1 takes place.
Respiration is a process of exchanging gas.
