Answer:
D
Explanation:
Pollutants tend to an increase in concentration in the fatty tissues of animals compared to the concentration of the same pollutant in the environment.
Also, tend to increase in the fatty tissues of organisms at each trophic level.
Hence, as a result of this, the highest concentration of the insecticide is accumulated by the organisms at the highest level of the food chain. So, the tertiary consumers accumulate the highest concentration of the insecticide.

Explanation:
High altitude adaptation is a complex physiological process that involves an increase in both the number of Hb molecules per erythrocyte and the total number of erythrocytes. It normally requires several weeks to complete. However, even after one day at high altitude, there is a significant degree of adaptation. This effect results from a rapid increase in the erythrocyte BPG concentration.
a. Try to do this without looking at the graphs. If oxygen-binding curves for both high altitude adapted hemoglobin and normal, unadapted Hb were plotted together, would the curve for high altitude adapted Hb be to the left of, to the right of or the same as the curve for unadapted Hb? Explain.
b. Is the oxygen binding affinity of high-altitude adapted Hb higher, lower, or the same as that of unadapted Hb? Explain.
Answers
Answer:
a. To the right
b. higher
Explanation:
From the information given:
a.
The oxygen-adsorption curve of the elevated high altitude modified the hemoglobin and this will move to the right because there is a reduced amount of oxygen available at high altitude, as well as an increase in carbon dioxide and H+ ion concentration, temperature, and all of which raise pH and shifts the curve towards the right.
b.
As there is a low relative partial pressure of oxygen at high altitude, the oxygen-binding attraction of high altitude adaptable hemoglobin is greater and higher than that of unadapted hemoglobin under pulmonary oxygen loading. This is important to optimize the oxygen concentration levels in blood circulation and blood tissues.

I will give brainly if your argument is convencing
Answers
Answer:
ok so like i think they do but it also makes things really complicated
Explanation:
becauuuuseeeee its the fact that for me i always think that maybe thats how the world birthed orrrrrrrr that all of this is a made up concept of life cause everything you think about is just another concept. anddddd it could just be like the matrix and its like hard to think about how everything we know couldd just be made up or pointless to the point where there is a point of living ykkkkk.
My argument runs like this. I’ll construe “science” as the set of tools we use to find truth about the universe, with the understanding that these truths are provisional rather than absolute. These tools include observing nature, framing and testing hypotheses, trying your hardest to prove that your hypothesis is wrong to test your confidence that it’s right, doing experiments and above all replicating your and others’ results to increase confidence in your inference.
And I’ll define religion as does philosopher Daniel Dennett: “Social systems whose participants avow belief in a supernatural agent or agents whose approval is to be sought.” Of course many religions don’t fit that definition, but the ones whose compatibility with science is touted most often – the Abrahamic faiths of Judaism, Christianity and Islam – fill the bill.
Next, realize that both religion and science rest on “truth statements” about the universe – claims about reality. The edifice of religion differs from science by additionally dealing with morality, purpose and meaning, but even those areas rest on a foundation of empirical claims. You can hardly call yourself a Christian if you don’t believe in the Resurrection of Christ, a Muslim if you don’t believe the angel Gabriel dictated the Qur’an to Muhammad, or a Mormon if you don’t believe that the angel Moroni showed Joseph Smith the golden plates that became the Book of Mormon. After all, why accept a faith’s authoritative teachings if you reject its truth claims?
Indeed, even the Bible notes this: “But if there be no resurrection of the dead, then is Christ not risen: And if Christ be not risen, then is our preaching vain, and your faith is also vain.”
Many theologians emphasize religion’s empirical foundations, agreeing with the physicist and Anglican priest John Polkinghorne:
“The question of truth is as central to [religion’s] concern as it is in science. Religious belief can guide one in life or strengthen one at the approach of death, but unless it is actually true it can do neither of these things and so would amount to no more than an illusory exercise in comforting fantasy.”
The conflict between science and faith, then, rests on the methods they use to decide what is true, and what truths result: These are conflicts of both methodology and outcome.
In contrast to the methods of science, religion adjudicates truth not empirically, but via dogma, scripture and authority – in other words, through faith, defined in Hebrews 11 as “the substance of things hoped for, the evidence of things not seen.” In science, faith without evidence is a vice, while in religion it’s a virtue. Recall what Jesus said to “doubting Thomas,” who insisted in poking his fingers into the resurrected Savior’s wounds: “Thomas, because thou hast seen me, thou hast believed: blessed are they that have not seen, and yet have believed.”
Two ways to look at the same thing, never the twain shall meet. Gabriel Lamza/Unsplash
And yet, without supporting evidence, Americans believe a number of religious claims: 74 percent of us believe in God, 68 percent in the divinity of Jesus, 68 percent in Heaven, 57 percent in the virgin birth, and 58 percent in the Devil and Hell. Why do they think these are true? Faith.
But different religions make different – and often conflicting – claims, and there’s no way to judge which claims are right. There are over 4,000 religions on this planet, and their “truths” are quite different. (Muslims and Jews, for instance, absolutely reject the Christian belief that Jesus was the son of God.) Indeed, new sects often arise when some believers reject what others see as true. Lutherans split over the truth of evolution, while Unitarians rejected other Protestants’ belief that Jesus was part of God.
And while science has had success after success in understanding the universe, the “method” of using faith has led to no proof of the divine. How many gods are there? What are their natures and moral creeds? Is there an afterlife? Why is there moral and physical evil? There is no one answer to any of these questions. All is mystery, for all rests on faith.
The “war” between science and religion, then, is a conflict about whether you have good reasons for believing what you do: whether you see faith as a vice or a virtue.
Compartmentalizing realms is irrational
So how do the faithful reconcile science and religion? Often they point to the existence of religious scientists, like NIH Director Francis Collins, or to the many religious people who accept science. But I’d argue that this is compartmentalization, not compatibility, for how can you reject the divine in your laboratory but accept that the wine you sip on Sunday is the blood of Jesus?

You are testing a new antibiotic in the microbiology lab. After treating Salmonella cells with the antibiotic, you wanted to see how many viable cells remain. Which of the following methods will provide the most accurate count of viable cells?
A. Fluorescence-activated cell sorting of unstained cells.B. Serial dilution followed by an optical density measurement.C. Counting cells directly using a hemocytometer.D. Serial dilution followed by a colony forming units calculation.
Answers
Answer:
D. Serial dilution followed by a colony forming units calculation.
Explanation:
The best way to count bacterial cells such as Salmonella accurately is through serial dilution and calculation of colony forming units.
Serial dilution is made using a petri dish containing appropriate culture medium for Salmonella growth. In this petri dish, with the help of an inoculation loop, the suspension containing the Salmonella will be scratched in the middle of the petri dish. Then, the inoculation loop will be passed over the salmonella streaks and will be dragged to the other side of the plate, where the loop will be scratched halfway through this space. The inoculation loop should again pass over the new salmonella streaks and be dragged through the rest of the petri dish. Then one must wait for the bacterial colonies to grow inside the plate.
Once these colonies are grown, those that appear in isolation will be counted through a specific calculation for the count of salmonella colonies.
In a Nitrogen metabolism study, the following data were obtained over the test period:
Nitrogen consumed 175 grams
Total Fecal N 35 grams
Metabolic Fecal N 10 grams
Total Urinary N 80 grams
Endogenous Urinary N 10 grams
Calculate:
a. Apparent Nitrogen digestibility (%)
b. True Nitrogen digestibility (%)
c. Nitrogen Balance (g)
d. Apparent Nitrogen Retention (%)
Answers
Answer:
a. 80%
b. 86%
c. 60 g
d. 34.29%
Explanation:
From the given information:
The apparent nitrogen digestibility (AD) is the ratio of the difference between the consumed nitrogen and fecal nitrogen to the consumed nitrogen.
Mathematically:
[tex]AD = \dfrac{consumed \ nitrogen - fecal \ nitrogen }{consumed \ nitrogen }[/tex]
[tex]AD = \dfrac{175 -35 }{175}[/tex]
AD = 0.8
To percentage, the apparent Nitrogen digestibility = 80%
b. True Nitrogen digestibility is calculated by the formula:
[tex]=\dfrac{consumed \ nitrogen - (fecal \ nitrogen -metabolic \ fecal)}{consumed \ nitrogen}[/tex]
[tex]= \dfrac{175 -(35-10)}{175}[/tex]
[tex]= \dfrac{175 -25}{175}[/tex]
= 0.86
= 86%
c. Nitrogen Balance = consumed Nitrogen - Fecal nitrogen - total uninary
Nitrogen Balance = (175 - 35 - 80) grams
Nitrogen Balance = 60 g
d. Apparent Nitrogen Retention (ANR) is computed as follows:
[tex]ANR = \dfrac{(consumed \ nitrogen-fecal\ nitrogen - total \ uninary )}{nitrogen \consumed }\times 100\%[/tex]
[tex]ANR = \dfrac{(175-35- 80 )}{175 }\times 100\%[/tex]
[tex]ANR = \dfrac{(60 )}{175 }\times 100\%[/tex]
ANR = 34.29%

Muscles are required in breathing, talking, running, walking, and any body movement. Actin and myosins are protein filaments present in muscle cells that help to contract and relax or change the shape of muscles. Muscles are responsible for the movement or motion of organisms. Joints are the connection between two or more bones. Most joints are mobile.
Muscle strength is determined by several factors. Some of those are the physical shape, size, and innervation of the muscles.

Answers
Answer:
Mechanoreceptors would be activated
Explanation:
The skin is a complex organ that is found covering the entire surface of the human body. The mechanoreceptors are responsible for the sense of touch, that is, the capture of pressure on the skin. They are the Meissner corpuscles and the Vater-Pacini corpuscles, which are made up of nerve endings and connective tissue, in other words, they are receptors that are stimulated by muscle contraction and pressure on the joint elements. It allows to know the position of the body and the degree of contraction of the muscles.

d. The occurrence of opportunistic infections ___________ in immunocompromised patients.
1. Higher
2. Lower
Answers
Answer:
a. lower
b.higher
c.lower
1.Higher
Explanation
Moisture is a great environment for bacteria to grow, the moister the environment is the more the bacteria will thrive, thinking about this lower moisture levels will result in lower microbial diversity.
The small intestine has higher ph than the stomach, this means that the bacteria there thrive in higher ph than the stomach bacteria.
Normal microbia in the skin usually acts as the first barrier against pathogens, while we have normal microbia it will protect us and will be less likely to get skin pathogens.
Immunocompromised patients are people that have received treatment to reduce their immunological system capacity, this means that even though this is done to battle a disease, another opportunistic infection can appear and take advantage of the fact that the defenses are low.
