Answer:
Blood plasma is a 'yellowish liquid' component of blood that holds the blood cells in whole blood in suspension. It is the liquid part of the blood that carries cells and proteins throughout the body. It makes up about 55% of the body's total blood volume. It is the intravascular fluid part of extracellular fluid. It is mostly water, and contains important dissolved proteins, glucose, clotting factors, electrolytes, hormones, carbon dioxide, and oxygen. It plays a vital role in an intravascular osmotic effect that keeps electrolyte concentration balanced and protects the body from infection and other blood disorders.

Will heterozygous genotypes have the same phenotypes as homozygous dominant alleles?
Answer:
For a gene that is expressed in a dominant and recessive pattern, homozygous dominant and heterozygous organisms will look identical (that is, they will have different genotypes but the same phenotype), and the recessive allele will only be observed in homozygous recessive individuals.

The host is neither helped nor hurt by the relationship and interaction with the parasitic organism. D. Both the parasite and the host are helped by the relationship and interaction with the parasitic organism.
Answer:
B. The parasite must utilize a host organiam that may or may not die as a result of the relationship
Explanation:
The reason it is B is because a parasite usually has to feed off the host this can vary from taking nutients to Something more severe like controlling the organizim to make more of the parasite.

In your OWN words, describe the cardiac cycle
Answer:
The cardiac cycle is defined as a sequence of alternating contraction and relaxation of the atria and ventricles in order to pump blood throughout the body. ... In other words, when the atria are in diastole, the ventricles are in systole and vice versa.The cardiac cycle describes all the activities of the heart through one complete heartbeat—that is, through one contraction and relaxation of both the atria and ventricles. ... The volume of the ventricles remains unchanged (isovolumetric) during this period.

Yes, the percent daily value (% DV) is a useful tool, even for people who don't consume a 2,000-calorie diet.
What is the percent daily value?The percent daily value may be defined as the value which is usually calculated by dividing the amount in a serving by the total recommended daily amount.
It indicates the value of each nutrient in a serving of the food specifically. It gives an idea to the person how more he/she is already taken in terms of calories or may be short with respect to daily recommendation limits.
Therefore, it is well described above.

WHY IS OXYGEN CLASSIFIED AS PURE SUBSTANCE AND AIR IS CLASSIFIED AS A MIXTURE?
CAN ANYBODY PLEASE HELP?
Answer:
I'm pretty sure it is because oxygen is a single atom and air has multiple atoms
Answer:
Here-
Explanation:
Air is a mixture of gases, 78% nitrogen and 21% oxygen with traces of water vapor, carbon dioxide, argon, and various other components.
Air isn't exactly pure its got all the gases mixed together, but when we breathe oxygen is pure because nothing else can make oxygen, its just O.
Air can still be air if it doesn't have carbon dioxide in it. It can still be air without water vapor. Also oxygen is a pure element on the periodic table.
Hope this helped. :))

Which of the following is a disadvantage of using solar energy?
A. Solar and angels are expensive
B. Solar energy is available only during summer
C. Solar panels do not work very well
D. Solar energy produces greenhouse gases
Answer:
a
Explanation:
Solar energy is expensive and solar energy works during every season, however the productivity drops, hence option A is correct.
What is the use of solar energy?The fact that solar energy might be temporarily disrupted by weather is one of its drawbacks. The amount of electricity you create is less on cloudy days. However, the cold has little impact on output.
Any energy produced by the Sun is referred to as solar energy. Direct or indirect human usage of solar energy is possible.
Solar energy is captured and transformed into power by these solar panels, which are installed on a roof. Solar water heaters and home heating are two common uses for solar energy.
Therefore, solar energy can also be used for cooking and as a source of power for technological equipment.

Should the FDA should give Aquabounty permission to grow and sell transgenic salmon? Why or why not?
Answer:
Yes it should be approved
Explanation:
The FDA should give Aquabounty permission to grow and sell transgenic salmon because studies have shown that transgenic salmons which are genetically modified are harmless. This finding has allayed the fears of the people. Permission to grow and sell this type of salmons will make it easier for transportation to other parts of the country because it doesn’t necessarily have to come from the sea. It also ensures there is increased availability of the products all over the country.

List ways that you can reduce, reuse, and recycle waste that you typically generate
Answer:
I typically generate a lot of paper as waste while using paper to write. I can follow the following ways to reduce, reuse, and recycle the paper waste.
When I photocopy a large document, I could reduce my use of paper by making double-sided photocopies, or I could only copy the portion of the document that I would actually use.
When I am done with a single-sided document, I can reuse the other side as scrap paper for working on math problems.
Finally, when I am done with my paper, I can recycle it instead of throwing it into the garbage. Many recycling centers accept paper. Moreover, there are bins for recycling near my school.

Answer:
To provide an experimental foundation for the theoretical concepts introduced in the lectures. It is important that students have an opportunity to verify some of the ideas for themselves.
2. To familiarize students with experimental apparatus, the scientific method, and methods of data analysis so that they will have some idea of the inductive process by which the ideas were originated. To teach how to make careful experimental observations and how to think about and draw conclusions from such data.
3. To introduce the methods used for estimating and dealing with experimental uncertainties, including simple ideas in probability theory and the distinctions between random (statistical) and systematic "errors." This is essential in understanding what valid conclusions can be deduced from experimental data and that, properly obtained, these conclusions are valid, notwithstanding the uncertainty of the data.
4. To learn how to write a technical report which communicates scientific information in a clear and concise manner.
5. To introduce new concepts and techniques which have a wide application in experimental science, but have not been introduced in the standard courses. These may require that the student consult additional textbooks.

What effects genetic variation and environmental factors have on organisms
Answer:
Explanation:
Evolutionary psychology seeks to understand the adaptive, evolved nature of humans by considering the forces of natural selection that gave rise to it. Individual humans also exhibit maladaptation, however, and some of the variation in maladaptive conditions is heritable. An evolutionary perspective can shed light on these phenomena too. Recent work suggests that developmental imprecision importantly affects the fitness of organisms and some of the genetic influences have been identified. Both theory and evidence that developmental imprecision underlies human cognitive maladaptation has begun to accumulate, although the manner in which the developing brain is affected remains largely unknown.

The muscles begin shivering on a cold, snowy day is n example of homeostasis. So, the correct option is (D).
What is Homeostasis?Homeostasis is defined as a state of stable internal, physical, and chemical conditions maintained by living systems that are optimal functioning conditions for the organism and includes many variables, such as body temperature and fluid balance, some being kept within pre-determined limits.
Homeostasis is the maintenance of optimal conditions for enzyme action throughout the body, as well as all cell functions which is the maintenance of a constant internal environment despite changes in internal and external conditions. In the human body, homeostasis include the control of: Blood glucose concentration. Some example of homeostasis is the muscles begin shivering on a cold, snowy day.
