a human organ is being prepared for transplant. in what type of solution must it be bathed?
A. A hypertonic solution
B. A hypotonic solution
C. Pure water containing solutes
D. A solution with the same osmolarity as the organ tissue
Answers
it must be bathed in a solution with the same osmolarity as the organ tissue.. inorder for it not to gain or lose its solute concentration.
I it is placed in a hypotonic solution it will gain water and eventually burst and if placed in a hypertonic solution it will lose water and shrink.
it must be bathed in solution with the same osmolarity as the organ tissue.
Osmosis allows for the diffusion of water from the region of higher concentration to the region of lower concentration.
Osmolarity measures the amount of solute concentration
For an organ place in a hypertonic solution i.e solution that has a higher solute
organ bathed in a hypertonic solution will continue to absorb in more water which can eventually burst the organ when it is too muchFor organ in hypotonic solution i.e solution that has a lower solute concentration
organ bathed will have to lose more solution because itself has more solute than the solution and can lead to shrinkagebut when the osmolarity is the same the Organ will have the same solute concentration as the solution and will help keep the organ in its original form, it will not absorb or lose any solution.

1. Alpha-gamma coactivation
A. is critical for preventing contraction of an antagonist muscle when the other muscle is contracting during voluntary
movement
B. is critical for maintaining the appropriate tension on the spindle organ during contraction of extrafusal fibers.
C. is the process by which Ca2+ is released from the sarcolemma when nicotinic acetylcholine receptors are activated
at the neuromuscular junction
none of the above
Answers
The correct option is B.
Alpha gamma coactivation is critical for maintaining the appropriate tension on the spindle organ during contraction of extrafusal fiber.
Alpha‐gamma coactivation is a process that the muscle use to keep or maintains it's length. It works in a way that when the muscle contracts or relaxes , the sensory neuron send the information to the central nervous system about what happen to the muscle. This lead the intrafusal and extrafusal fibers to contract.
Alpha-gamma coactivation enhance the muscle spindles ensure its sensitivity to stretch the muscle lengths.
Therefore, Alpha gamma coactivation is critical for maintaining the appropriate tension on the spindle organ during contraction of extrafusal fiber.

Under dehydration circumstances in the winter, stomata may close to reduce water loss for the tree. Predict what would result from the closing of stomata. es ) A This would provide more water, increasing photosynthesis. B) This would also stop gas exchange and further limit photosynthesis. This would trap the oxygen produced in photosynthesis and kill the plant. D) This would help the needles gather more sunlight energy, increasing photosynthesis. Energy Transfer
Answers
Answer:this would also stop gas exchange and further limit photosynthesis
Explanation: did this on USA test prep and got it right
This would also stop gas exchange and further limit photosynthesis. Therefore, option B is correct.
What is the mechanism of opening and closing of stomata?The content of cell sap is reduced as a result of the conversion of the organic acids into starch. This causes water to exit hard cells, and a decline in their turgor causes the stomata to close. Stomata therefore open throughout the day and close at night.
The pH of the guard cells controls stomatal opening, according to the starch sugar interconversion theory of stomatal opening. In neutral or alkaline pH, stomata open. When the guard cells are open during the day and closed at night, they contain starch during the day.
Under dehydration circumstances in the winter, stomata may close to reduce water loss for the tree. This would also stop gas exchange and further limit photosynthesis. Therefore, option B is correct.

Membrane-bound organelles are cellular structures that are bound by biological membrane. Examples of membrane-bound organelles are nucleus, endoplasmic reticulum, Golgi apparatus, mitochondria, plastids, lysosomes and vacuoles.
Have a great day friend! :D
Answer:
Organelles play an important role in a variety of cell processes. The nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, vesicles, and vacuoles are all organelles found in animal cells. Although ribosomes are not surrounded by a membrane, they are nonetheless referred to as organelles in eukaryotic cells.
Explanation:
ORGANELLESAn organelle is a specialized subunit of a cell that has a defined role in cell biology. The name organelle stems from the idea that these structures are sections of cells, similar to how organs are parts of the body, therefore the diminutive suffix -elle. Organelles are either independent lipid bilayer-enclosed functional units (also known as membrane-bound organelles) or spatially distinct functional units without a lipid bilayer surrounding them (non-membrane bound organelles). Although most organelles are functional units within cells, some functional units that extend outside of cells, such as cilia, the flagellum and archaellum, and the trichocyst, are often referred to as organelles.Learn more about Organelles here

Coronary heart disease is the main cause of death in our country. The following factors can increase the risk of an individual contracting this disease:
-smoking
-unbalanced diet
-unhealthy lifestyle
Explain how these factors can contribute to coronary heart disease.
Answers
Smoking :-
The coronary arteries inside us are responsible for supplying our heart muscles with O₂ rich blood. When people smoke, plaque builds up in the arteries & the O₂ rich blood will not get supplied to the hear muscles causing atherosclerosis / coronary heart disease.
Unbalanced Diet :-
Eating an unhealthy diet which is high in cholesterol & fats also causes atherosclerosis (coronary heart disease). Too much salt in the diet can also raise blood pressure which is another factor responsible for this disease.
Unhealthy Lifestyle :-
Unhealthy lifestyles like not exercising at all & being obese lead to atherosclerosis (coronary heart disease).

5. Why do you think it's important to look at the impact on the ecosystem as a whole, instead of just the individual"?
Answers
Answer:
Ecosystem Services are the benefits nature provides to human well-being. The term is frequently thrown around in academic circles, but why should you care about them?
Although the term is quite new, our connection to nature is not. We depend on nature for our survival - without healthy ecosystems, our drinking water isn’t clean nor is the air we breathe. We also enjoy nature... studies show that people who spend time in nature tend to be happier than those that don’t. It can even act as a natural anti-depressant. With industry and urban sprawl expanding at unprecedented rates, Ecosystem Services attempt to translate the benefits we receive from nature into economic terms so we can better understand the trade-offs we are making between nature and industrial development.
This brings us to the reasons why we feel Ecosystem Services are important to each and every person:
1. Boundless Benefits
Understanding nature in economic terms, while not perfect, allows us to put everything into the same comparison unit. Despite nature being such an integral part of the human existence, it is sometimes an afterthought in today’s economy. Nature and money are often on competing terms, so to make a more level playing field, environmental economists have tried to bridge this gap by placing a monetary value on the benefits nature provides.
A recent study estimated the combined benefits of nature to people at well over $100 USD trillion per year. To put this in perspective, the top 50 most profitable companies globally combine to make just under $10 USD trillion per year.
Valuing nature in a way that can speak to decision makers, may help promote conservation efforts in the future. It brings nature back into the cost-benefit discussion in a way that can be easily understood.
2. The Foundation For Sustainable Development
Ecosystem Services help measure the true cost of industrial development. Often, the impact industrial development has on the economy and job creation overshadows the cost it will have on surrounding lakes, forests, keystone species, and so on. Assigning a dollar value to these lakes and forests, and the Ecosystem Services they provide, helps adjust the cost benefit analysis by evaluating the negative effects development will have on the natural environment.
Companies have also started to use Ecosystem Services in conservation offset planning, where they can buy and sell credits to offset a development or set aside land to meet a specific offset. Sustainable development supports the maintenance of a healthy economy while also protecting the ecological process for future generations.
3. Essential For Our Survival
Whether you live in rural Newfoundland or downtown Los Angeles, your dependence on Ecosystem Services is the same. As a society, we depend on healthy ecosystems to do many things; to purify the air so we can breathe properly, sequester carbon for climate regulation, cycle nutrients so we have access to clean drinking water without costly infrastructure, and pollinate our crops so we don’t go hungry. As the world’s population continues to grow, so too does our dependence on healthy ecosystems to provide the necessities essential to our survival.
Don’t we all want to leave the planet in a good condition for our successors? Ecosystem Services valuation and assessment is one way to help make this happen. By clearly understanding their value, we can make the best and most informed decisions about how to manage our landscape to ensure this value isn’t lost.
