Answer: The statement is TRUE.
Explanation:
Gram negative bacteria is a type of bacteria that possesses, from the interior to the exterior, a cytoplasmic membrane, a thin peptidoglycan layer, and an outer membrane containing lipopolysaccharide. The lipid portion of the lipopolysaccharide complex of the outer layer acts as an ENDOTOXIN.
The endotoxin of the gram negative bacteria can be detected in research or biomedical laboratories through a technique called LIMULUS AMEBOCYTE LYSATE test.
The test procedure follows a principle that the endotoxin of these gram negative bacteria are capable of forming gel clots (coagulation) of blood cell (amoebocytes) lysates of the Limulus polyphemus crab.
Therefore, If LAL (limulus amebocyte lysate) turns into a gel when exposed to a sample, it
means the sample is contaminated with endotoxins of gram-negative bacteria.

What is another term for the responding variable?
O primary variable
dependent variable
independent variable
uncontrolled variable
The answer is DEPENDENT VARIABLE
-edgy 2021
Answer:
B. Dependent variable.
Explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
Hence, an experiment is used by scientists or psychologists to illustrate how a change in variable affects behavior.
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
In an experiment, there are two (2) main types of variables and these are;
I. Independent variable: this is the variable that is being manipulated or alters and as such it is the cause of a behavior. This variable stands alone.
II. Dependent variable: this variable is the direct effect of the actions of the researcher in an experiment.
Basically, the dependent variable is the variable that is being measured and tested by an experimentalist.
Hence, dependent variable is another term for the responding variable because it responds to an action.

Your treatment choices are saline solutions with different amounts of salt (NaCl) that can be added to
Clark's blood and affect osmosis in the brain.
In medicine and veterinary medicine, saline solutions are compared with the normal concentration of
sodium (~143 mmol/L) in healthy blood. Three saline solutions are available: isotonic, hypotonic, and
hypertonic.
Concentration of Sodium
Interpret each as higher, lower, or equal to
normal blood Nat concentration.
Lower
Equal Higher
Isotonic Saline
Hypotonic Saline
000
Hypertonic Saline
Answer: isotonic saline is equal
Hypotonic saline is lower
Hypertonic saline is higher
Explanation:
Here, three saline solutions are available: the isotonic saline solution has an equal sodium concentration, the hypotonic solution has a lesser sodium concentration, and the hypertonic solution has a high sodium concentration.
What is the significance of the saline solution in the medications?It is critical in the medication because the solution is made up of a mixture of salt and water through which the drugs are delivered and because it is given in intravenous (IV) therapy or to rehydrate patients when there is a need for it. The saline concentration should be regulated here in this solution, or else it may change the blood cells' structure.
Hence, here, three saline solutions are available: the isotonic saline solution has an equal sodium concentration, the hypotonic solution has a lesser sodium concentration, and the hypertonic solution has a high sodium concentration.

Mentoring is considered as a mechanism, which assists in transmitting the standards and values of professional conduct.
• A mentor is an individual who advise, support, and guide the person.
• Mentoring is a process or an act of guiding and helping another person to support their personal development.
• The main objective of mentoring is to assist one to grow as a person and become the best version of oneself.
• This helps one in attaining the personal or career goals, presenting one to novel ways of thinking, sharing valuable life lessons, challenging one limiting assumptions, and much more. In short, mentoring helps an individual to attain the values and standards of professional conduct.
Thus, mentoring helps one to attain the values and standards of professional conduct.

Your friend is an avid swimmer and wants to burn the most calories in her 20 minute daily swim. She has a choice of swimming in a pool with a water temperature of 80°F (26.7°C) or one with a water temperature of 72°F (22.2°C).
Which pool should your friend choose to achieve her goal? Explain why.
Answer:72
Explanation:
The water is colder so you would burn more calories.
Far more calories are burned during cold water swimming than swimming in warmer water. The main idea behind this is a fact that cold water decreases the body temperature so much that the body must act to maintain temperature homeostasis.
What is Swimming?Swimming is a preferred sports activity for burning of calories faster. It is because the resistance of water is so much higher and consistent than that of air, it becomes easier to burn calories by swimming than running. Swimming is a full body workout, that results in more calories burned.
When the temperature of water drops, the metabolism increases up to keep the body warm and people starts shiver, etc. Swimming in cold water will make the body work twice as hard to keep warm and burn more calories in the process. This is one reason why people lose more weight when swimming regularly in cold water than warmer water.

What process occurs at the boundary between the capillaries and the alveoli?
A.
Nitrogen enters the alveoli, and oxygen enters the capillaries.
B.
Oxygen enters the alveoli, and carbon dioxide enters the capillaries.
C.
Oxygen enters the alveoli, and nitrogen enters the capillaries.
D.
Carbon dioxide enters the alveoli, and oxygen enters the capillaries.
Answer: D. Carbon dioxide enters the alveoli, and oxygen enters the capillaries.
Explanation:
This describes the exchange of gases in the lungs. When blood from the rest of the body gets to the lungs through the capillaries, oxygen flows from the alveoli which are tiny air sacs in the lungs, into the blood in the capillaries.
Carbon dioxide from the blood brought to the lungs will then flow into the alveoli which will then expel it through the nose. This repeated process ensures that the body keeps getting oxygen and expelling carbon dioxide.

The two ways in which white blood cells fight pathogens that have entered the body are "they produce antibodies that work against the pathogens and they surround and destroy the pathogens".
What are pathogens?Any organism as well as an agent that could cause the disease would be a pathogen in the widest and oldest sense.
What are antibodies?Whenever the immune system of the body recognizes dangerous compounds, known as antibodies, it produces a protein designated an antibody.
Therefore, the two ways in which white blood cells fight pathogens that have entered the body are "they produce antibodies that work against the pathogens and they surround and destroy the pathogens".

Suppose that a cytoplasmic protein (a protein that will function in the cytoplasm inside of the cell) is synthesized by a particular cell type. Describe the route that this protein will take from the moment its synthesis starts in the nucleus until it makes it into the cytoplasm.
Answer:
A specific gene that contains the information to encode the target protein is transcribed as a primary transcript (pre-mRNA). Subsequently, the pre-mRNA is processed to form a mature mRNA. Finally, this mRNA then moves through a nuclear pore from the nucleus to the cytoplasm where proteins are translated in the ribosomes
Explanation:
The cell nucleus contains the majority of the cell's genetic material localized on linear molecules called chromosomes. During transcription, genes (specific chromosome segments) are used to synthesize primary transcripts (pre-mRNAs) which are then proceeded to produce mature messenger RNAs (mRNAs). RNA processing involves the removal of non-coding intron regions and the joining of coding exon regions (RNA splicing) in order to form a mature mRNA sequence. Subsequently, the mature mRNA leaves the nucleus through the nuclear pores of the nuclear membrane and travels to the ribosomes where is decoded (translated) to produce a specific polypeptide chain (i.e., a protein). Within the ribosome, the mRNA strand binds to multiple transfer ribonucleic acids (tRNAs) via complementary and consecutive three-nucleotide mRNA sequences called triplets or codons, and tRNAs deliver specific amino acids that are consecutively added to the polypeptide chain.
