What are some possible short and long-term medical concerns for crewmembers on longer space exploration ships
Answer:
Human travel to Mars and beyond is no longer science fiction.
Through shuttle research we know how the body changes, what we
need to do to fix some of the problems or—better yet—prevent them,
the importance of monitoring health, and how to determine the
human body’s performance through the various sequences of launch,
spaceflight, and landing. Basically, we understand how astronauts
keep their performance high so they can be explorers, scientists,
and operators.
Astronauts change physically during spaceflight, from their brain,
heart, blood vessels, eyes, and ears and on down to their cells.
Many types of research studies validated these changes and
demonstrated how best to prevent health problems and care for the
astronauts before, during, and after spaceflight.
During a shuttle flight, astronauts experienced a multitude of
gravitational forces. Earth is 1 gravitational force (1g); however,
during launch, the forces varied from 1 to 3g. During a shuttle’s
return to Earth, the forces varied from nearly zero to 1.6g, over
approximately 33 minutes, during the maneuvers to return. In all,
the shuttle provided rather low gravitational forces compared with
other rocket-type launches and landings.
The most pervasive physiological human factor in all spaceflight,
however, is microgravity. An astronaut perceives weightlessness and
floats along with any object, large or small. The microgravity
physiological changes affect the human body, the functions within the
space vehicle, and all the fluids, foods, water, and contaminants.
We learned how to perform well in this environment through the
Space Shuttle Program. This information led to improvements in
astronauts’ health care not only during shuttle flights but also for the
International Space Station (ISS) and future missions beyond
low-Earth orbit. Shuttle research and medical care led directly to
improved countermeasures used by ISS crew members. No shuttle
mission was terminated due to health concerns.

Answer:how am i supposed to answer?
correct answers are:
Salad dressing is an example of a homogeneous mixture. - False
The simplest type of substance is a compound. - False
When elements combine to form compounds, their properties do not change. - False
The chemical symbol for water is H20. - False
Substances in a mixture keep their own properties. - True
The substances in a heterogeneous mixture can usually be seen and are easily separated. - True
Salad dressing is typically a heterogeneous mixture. It consists of various ingredients, such as oil, vinegar, herbs, spices, and sometimes other additives. The simplest type of substance is an element, not a compound. An element consists of only one type of atom and cannot be broken down into simpler substances by ordinary chemical means. When elements combine to form compounds, their properties often change. Compounds have unique chemical and physical properties that are different from the properties of the individual elements that compose them.The chemical symbol for water is H2O, not H20. In a mixture, the substances retain their individual properties. They do not chemically combine or react with each other. In a heterogeneous mixture, the components are not uniformly distributed and can often be seen as distinct phases or particles.

What is the net ATP gain at this stage of cellular respiration?
Answer: ok since i dont know specifics heres what i can give u
Most biochemists agree that in prokaryotic microorganisms, a total of 36 molecules of ATP can be produced during cellular respiration. In eukaryotic cells, the number is 34 molecules of ATP. Two molecules of ATP are produced as the net gain of glycolysis, so the grand total is 38 molecules of ATP (36 in eukaryotes).
Krebs cycle
The Krebs cycle takes place inside the mitochondria. The Krebs cycle produces the CO2 that you breath out. This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle).
2 ATP
The net energy gain in fermentation is 2 ATP molecules/glucose molecule. In both lactic acid and alcoholic fermentation, all the NADH produced in glycolysis is consumed in fermentation, so there is no net NADH production, and no NADH to enter the ETC and form more ATP.
Glycolysis breaks down glucose (6-C) into two molecules of pyruvate (3C), and also produces: Hydrogen carriers (NADH) from an oxidised precursor (NAD+) A small yield of ATP (net gain of 2 molecules)
this is what i can give u their are so many stages of cellular respiration i cant give all the details
2 ATP, 2 NADH, and 2 pyruvate are produced. Pyruvate digestion and the citric acid cycle produce more ATP and high-energy electron carriers.
What is cellular respiration?ATP, which can be utilized as a source of energy to fuel many different reactions throughout the body, is produced as a byproduct of cellular respiration, which is a sequence of chemical events that breaks down glucose. Glycolysis, the citric acid cycle, and oxidative phosphorylation are the three primary stages that are involved in the process of cellular respiration.
The end result is two molecules of ATP, two molecules of NADH, and two molecules of pyruvate. The later steps of the metabolic pathway, such as the digestion of pyruvate and the citric acid cycle, result in an increase in the amount of ATP and high-energy electron carriers that are created.

How many water molecules would be needed to break amylose down into four glucose molecules?
Answer: 3 molecules of water to break down whatever sugar it is into four glucose molecules
Explanation: Amylose does not break down into four glucose molecules. Amylose acts on some sugar (which is four times larger than glucose, stachyose for example) and produces four glucose molecules.

Explain why a change in extracellular Na did not alter the membrane potential in the resting neuron.
Answer:
Explanation:
A change in extracellular Na did not alter the membrane potential in the resting neuron because the plasma membrane of a neuron is composed of little Na+ leakage channels and it is slightly permeable to few Na, thus lead to reduction in diffusion if Na inside and outside the cells.

Describe the pulmonary circulation by detailing the flow of blood from the right ventricle to the left atrium. Include the names of the blood vessels. Nadia
Answer:
Explanation:
Pulmonary circulation refers to a part of the circulatory system involve in carrying deoxygenated blood away from the right ventricle to the lungs and then carries oxygenated blood to the left atrium and ventricle of the heart.
Deoxygenated blood leave through the right ventricle by passing the pulmonary atrium. At the right atrium,the blood us pumped and move into the tricuspid valve into the right ventricle. The blood is then pumped from the right ventricle from the pulmonary artery. The pulmonary arteries carry deoxygenated blood into the lungs and here carbondioxide is removed and oxygen is use for respiration. Oxygenated blood is carried away from the lungs through the pulmonary veins which then return the blood to the left chamber of the heart completing the pulmonary cycle. Tye blood flow to the left atrium which is pumped to the left ventricle through mitral valve. From the left ventricle, the blood flow through the aorta through the aortic valve which distribute the blood to all part of the body and pulmonary circulation begins again.

Intracellular pathogens sometimes produce ________ that can kill phagocytes. Intracellular pathogens sometimes produce ________ that can kill phagocytes. PRRs leukocidins PAMPs lipopolysaccharides
Answer:
Leukocidins.
Explanation:
Intracellular pathogens sometimes produce leukocidins that can kill phagoctytes because leukocidins is a type of cytotoxin that is produced by pathogens which kill the phagocytes producing pathogens. The phagocytes destroy pathogens by engulfing the pathogens and destroying it by chemical toxins present inside the phagolysosome which is by a process called phagocytosis. The leukocidin kill phagocytes that engulf the pathogens making the pathogens to be able to affect the organism in which it invade.
