The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body. Your heart has four separate chambers that pump blood, two on the right side and two on the left. How does blood flow through the heart? Blood flows through your heart and lungs in four steps: The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle through the tricuspid valve.
what is the oxygen cycle ?

in phantom limb syndrome, which sensory pathway is responsible for conveying the sensory neuron activities?
The experience of the phantom limb syndrome involves the subjective sensation of the patient, the processes involved in this sensation are: both sensitive activity and the motor pathway.
The somatic nervous system is made up of mixed nerves (mixtures of sensory and motor axons) that emerge from the central nervous system, innervate the somatic effectors (skeletal muscles).Somatic motor pathways begin in the motor areas of the cerebral cortex, the projection neurons in that cortex emit axons that descend through the brain stem until they reach the spinal cord.Patients with this syndrome experience the sensation that the amputated limb is still attached to their body, since the brain continues to receive messages from the nerves that originally carried the impulses from the lost limb.Therefore, we can conclude that Phantom Limb Syndrome is the perception of sensations, which include pain of an amputated limb, where both sensory activity and the motor pathway have an action on said sensations.

What is reactivity and what does is have to do it chemistry
Answer:
In chemistry, reactivity is a measure of how readily a substance undergoes a chemical reaction. The reaction can involve the substance on its own or with other atoms or compounds, generally accompanied by a release of energy. The most reactive elements and compounds may ignite spontaneously or explosively.

What effect does increase salinity have on the density of water?
1. No affect unless temperature also changes
2. Decreases density
3. Increases density
Answer:
3
Explanation:
For example,The density of seawater depends on the content of salt. It is known that the density of salt is 2.165g/cm3, so the more salt, the greater the density of mixed liquid.
Answer:If you know that dissolution of salt only marginally affects the volume of the solution, how would you expect the density to evolve? It should reasonably increase.
Explanation:
at a given temperature, Should salts be dissolved in the water, and the volume remains reasonably constant, the density
. A solute binds water molecules around itself in a coordination sphere, and should a salt be dissolved, both anion and cation must be solvated; hence an increase in solution density with respect to water.
The scientific community disagrees about _______. A. The rate of global climate change b. The occurrence of global warming c. The need for action d. All of the above Please select the best answer from the choices provided A B C D.
The scientific community disagrees about the rate of global climate change (Option A). The occurrence of global warming is widely accepted by the scientific community.
Global climate change refers to the fluctuations in temperatures worldwide.
Global climate change is caused by the use of fossil fuels such as oil, coal and natural gas, which are known to be associated with the increasing concentration of greenhouse gases in the atmosphere.
The greenhouse gases include, among others, carbon dioxide (CO2) and methane (CH4).

Complete this sentence. Excess ____________ from human activities can cause harmful algal blooms (HABs), such as red tide, that produce toxic effects on aquatic species, marine mammals, and birds, as well as on the humans who eat them.
Nitrogen
Carbon
Salt
Heat
Answer: Nitrogen
Explanation:
Harmful algal blooms can occur in lakes, reservoirs, rivers, ponds, bays and coastal waters, and the toxins they produce can be harmful to human health and aquatic life. Harmful algal blooms are mainly the result of a type of algae called cyanobacteria, also known as blue-green algae.
The answer is nitrogen, nitrogen helps algae grow and when it grows in excess it takes away the dissolved oxygen from the water which kills off fish, which puts more nitrogen in the water making algae grow even more until it snowballs and destroys the aforementioned ecosystem.

Where, in terms of an ellipse, is the Sun located with respect to the orbit of each planet? Which
one of Kepler's Laws does your answer support?
Answer:
focus
The Sun is at one focus. The planet follows the ellipse in its orbit, meaning that the planet to Sun distance is constantly changing as the planet goes around its orbit. Kepler's Second Law: the imaginary line joining a planet and the Sun sweeps equal areas of space during equal time intervals as the planet orbits.
What is the metabolic process that breaks down organic molecules to release energy to be used by cells?
A. cellular respiration
B. light dependent cycle
C. light independent cycle
D. photosynthesis
Cellular respiration in living tissues is reduced at low temperatures. The amount of kinetic energy needed for chemical reactions like cellular respiration to occur decreases as temperature rises. Thus, option A is correct.
What importance of cellular respiration in an organism?As oxygen tension dropped, so did breathing rate, which eventually reached nil at low oxygen tensions.
Cell density had no bearing on this outcome. We provide a model to explain the observed impact of oxygen tension on cellular oxygen uptake.
As a result, increased cellular respiration is often associated with warmer temperatures.
Carbon dioxide concentration: The rate of respiration is inversely correlated with carbon dioxide concentration.
Increased carbon dioxide levels and a lack of oxygen have a negative impact on aerobic respiration rate.
Therefore, cellular respiration is the metabolic process that breaks down organic molecules to release energy to be used by cells.

a. Be converted to fructose-2,6-bisphosphate in a liver cell
b. Become a glycerol backbone in a triglyceride in an adipose cell
c. Become part of a fatty acid chain in a triglyceride in an adipose cell
d. Be polymerized into glycogen in a skeletal muscle cell
e. Be phosphorylated and bind allosterically to glycogen synthase
Answer:
e. Be phosphorylated and bind allosterically to glycogen synthase
Explanation:
The initial step in the pathways that utilize glucose is its phosphorylation in C6. Glucose-6-phosphosate
The statement that is true is phosphorylated and binds allosterically to glycogen synthase. The correct option is e.
What is phosphorylation?Phosphorylation is a biological process in which a phosphate group is added to an organic molecule. Phosphorylation processes include the following:
1) phosphate added to glucose to generate glucose monophosphate
2) Phosphate addition to adenosine diphosphate (ADP) to generate adenosine triphosphate (ATP).
Phosphorylation regulates several biological functions, including cell cycle, proliferation, death, and signal transduction pathways.
ADP-phosphate group of a reactive intermediate with the transfer of a chemical reaction in which ATP is created in substrate level phosphorylation.
Therefore, the correct option is e. Be phosphorylated and bind allosterically to glycogen synthase.

Which of these are causes of long-term climate change? Check all that apply.
Answer:
Where are the answers?
Explanation:
Answer: Earths orbit around the sun, solar energy, and volcanic eruptions
Explanation:
Earths orbit: At other times, the ellipse is more pronounced, so that the Earth moves closer and further away from the Sun in its orbit. When the Earth is closer to the Sun, our climate is warmer and this cycle also affects the length of the seasons.
Solar energy: Solar produces less life-cycle GHG emissions than conventional fossil fuel energy sources.
Volcanic eruptions: Volcanic eruptions of this magnitude can impact global climate, reducing the amount of solar radiation reaching the Earth's surface, lowering temperatures in the troposphere, and changing atmospheric circulation patterns.
