You and your friends go to the beach for vacation. You all walk down to the beach to go swimming. When you get there, you see the water is murky and green, and there are algae blooms floating on top. If it is excess nutrients which are feeding the algae blooms and lowering the oxygen content in the water, that process is called:_______.a. nutrient cycling.
b. nitrification.
c. eutrophication.
d. hypoxia.
Answers
Answer: The process is called EUTROPHICATION. The correct option is C.
Explanation:
Eutrophication is a type of environmental pollution where by there is an increase in nutrient salts of a water body which can lead to structural changes in the affected aquatic ecosystem. These changes includes:
--> Increase in production of algae: this effect causes algae blooms which makes the water murky, greenish and unpleasant for certain activities such as swimming.
--> Decrease in aquatic life: the presence of excessive growth of algae which are often degraded by microorganisms. When the rate of degradation of the algae by microorganisms is greater than that of oxygen regeneration a hypoxic state occurs which is harmful to aquatic life example fishes.

Answers
Answer:
Protection
Explanation:
The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell. And that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.
In rigor mortis, muscle tissue becomes locked in position because myosin heads are tightly attached to neighboring actin thin filaments. This lock-up is prevented in living muscle because ordinarily myosin is rapidly displaced from the thin filament by:_________.A. binding of a new molecule of ATP B. hydrolysis of ATP C. release of ADP after ATP hydrolysis D. release of phosphate after ATP hyrdolysis
Answers
Answer:
The correct answer is option A. binding of a new molecule of ATP.
Explanation:
Actin and myosin are complementary filaments present in muscle, actin is thin and myosin is a thick filament, these two filaments are responsible for the movement by muscle contraction and relaxation. Actin and myosin head shows great affinity towards one another.
Myosin heads are tightly attached to neighboring actin thin filaments due to its affinity to actin, however, myosin at other pockets also show a huge affinity for ATP. If myosin is bound to actin the affinity for ATP is changed and if new ATP bounds to the empty pockets it changes the conformation of myosin and prevents lockup or binding of the actin-myosin protein.
Discuss how a pathogen causes an infection. Include definitions for primary pathogen, opportunistic pathogen, infection, disease (caused by a living organism), and various stages of pathogenesis. You can choose a specific organism to describe
Answers
Answer:
Infections are generated by pathogens, pathogens that generate a rare invasion triggering an extremely risky condition for the host, opportunistic infections are usually caused by highly pathogenic microorganisms with high resistance mechanisms and are really serious signs and symptoms.
Primary pathogen is one that colonizes in a primary way by forming a biofilm or a microbiological ecosystem.
The great difference between infection and infectious disease is that the infection is the presence of microorganisms that cooperate and live with the host without generating pathology, whereas infectious disease is when these microorganisms generate a pathology or condition in the host.
Explanation:
The pathogenesis are different stages that make up the ability of a microorganism to get sick, an example is prevotella parvula or treponema denticola that during pathogenesis they quickly invade the tissues due to their movements, in addition to the tissues such as the mucosa they generate an immune distraction that release toxins in different areas to the invasion.
These are pathogenicity mechanisms, that is, how the microorganism does to be able to invade the tissues in the most oppressive way.

What is bone?Bone has a connective tissue which has been metabolically active and the main function of the bone has to provide mechanical as well as structural support as well as perform movement, and protect important organs of the body.
The bone has been made up of the bone cells known as the osteocytes and extracellular matrix. The total number of bone of the human body contain has 206 bones including bones of spine, legs, arms, ribs, and skull.
Bones are made up of calcium and carbonate and they have bone marrow in which blood cells are produced. By nature bones came in category of living and they are active tissue .
There are several types of bones such as the flat bones, short bones, sesamoid bones, and long bones. The function of bone has to protect vital organs of the body.

There is a healthy bacterial culture growing in the exponential phase . A technician wants to make a growth curve by making cell counts over the day . She plans to take the samples every 30 minutes during the day , hold the samples at room temperature , and then process all samples together at the end of the day .
A) what is the problem with her plan?
B)can she do anything to improve the accuracy of her results ?
Answers
A) WHAT IS THE PROBLEM WITH HER PLAN?
Binary fission is one of the asexual process by which most bacteria reproduce, the binary fission brings about a doubling of the number in bacterial cells that are viable.
Generation time is that time that it will require for a cell population to divide and double, it is also known as doubling time. This Generation time varies among distinct organisms and also varies among culture conditions.
Take for instance,a fast growing bacterium that is under an ideal culture conditions has a doubling time of 20minutes and for the bacteria that is grown in a condition that is not so ideal,may have a doubling time of hours.
The major challenge/ problem with her plan is that as she takes the bacterial sample every 30minutes, and then hold the sample till the last sampling is done in the day,those bacterial cells that are collected in the initial intervals will then get divided and further gives a result that is false.
However,if those bacteria that are collected aren't stored in a culture environment that is standard,the bacterial cells may die off and thus will further bring about a false result.
2) CAN SHE DO ANYTHING TO IMPROVE THE ACCURACY OF HER RESULT?
Solution for rectifying the error in her plan;
She can go ahead and add 50-100 μl of formaldehyde to all the culture suspensions that she has and has taken every 30minutes.
As the formaldehyde will fix the bacterial cells,The optical density present in all those aliquots can then be retrieved/taken at the end of the day.
Looking at it alternatively, aliquot 1ml of the culture suspension at an interval of every 30 minutes,and then take the optical density that is OD at a wavelength of 600nm making use of spectrophotometer until the reason you get becomes static.

Explanation:
What happens to the actin and myosin during a muscle contraction?
Answers
Answer:
Once the myosin-binding sites are exposed, and if sufficient ATP is present, myosin binds to actin to begin cross-bridge cycling. Then the sarcomere shortens and the muscle contracts. In the absence of calcium, this binding does not occur, so the presence of free calcium is an important regulator of muscle contraction.

You are given a protein with the following amino acid sequence:
methionine (nonpolar)-glycine (nonpolar)-serine (polar)-alanine (nonpolar)-lysine (polar)
If an amino acid substitution occurred in this polypeptide chain, predict which option would have the most
significant impact on the structure and function of the protein.
a. Serine is replaced by lysine (polar)
b. Glycine is replaced by alanine (nonpolar)
c. Alanine is replaced by leucine (nonpolar)
d. Lysine is replaced by tryptophan (nonpolar)
?
Answers
Answer:
d. Lysine is replaced by tryptophan (nonpolar)
Explanation:
Amino acid substitutions can have varying affects on the protein function, depending on the specific substitution and the location of the substitution.
If the substitution occurs in an important region, for example an enzyme active site, then the function of the protein could be destroyed.
Additionally, if the substitution replaces the amino acid with a highly different amino acid with different properties (eg. polarity), it could alter the structure and function of the protein.
Replacing lysine (polar) with a tryptophan (non-polar) changes the properties of the amino acid at that location, whereas the other substitutions do not.
