Answer and explanation:
Sickle cell anemia is a type of anemia that occurs because of a mutation in the HBB gene, which codifies for the beta subunit of hemoglobin, producing an abnormal beta-globin called Hemoglobin S o HbS. This anomalous beta subunit is a product of the replacement of the amino acid glutamic acid by the amino acid valine at position 6, resulting in a beta-globin that forms a long and rigid molecule turning red blood cells shape into a sickle one, condemning erythrocytes to a premature death (which will cause the anemia). Another complication patients with sickle cell anemia can have is the blocking of blood vessels because of the abnormal and rigid shape of their red blood cells.
Calculate the angle of impact for a blood droplet whose width is 6.8 mm and length is 7.2 mm.
1.)94°
2.) 16°
3.) 1°
4.) 71°
Answer:
71°
Explanation:
To obtain the angle of impact :
The length of blood stain = hypotenus
The width = opposite
Hence,
Hypotenus = 7.2 mm ; Opposite = 6.8mm
Angle of impact, θ = sin^-1(opposite /hypotenus)
θ = sin^-1(6.8/7.2)
θ = 70.8°
θ = 71°

A blood bank refused to accept blood from a potential donor who had just had his teeth cleaned by a dental hygienist. Why did they refuse the blood
Answer:
High amounts of fluoride
Explanation:
Teeth cleaning agents can contaminate one's blood with fluoride, something that it is only healthy to accumulate a small amount of.
A blood bank would refuse the blood of the potential donor because the cleaning agents of teeth significantly accumulate heavy metals in the blood of an individual.
Why teeth are required to be cleaned by a dental hygienist?Teeth are required to be cleaned regularly on their own. But if you are facing some problems like tooth decay you must have to consult with a dental hygienist in order to ensure the health of teeth and gums.
According to the context of this question, a dental hygienist uses a variety of cleaning agents while cleaning the teeth of a patient. Due to this, the accumulation of concentration of heavy metals like fluoride and lead is increased in the blood directly or indirectly.
Apart from this, this person also has genetic inheritance of tooth decay and other diseases. So, the blood bank refused to accept blood from a potential donor.

Explanation:
If plants are absorbing and using blue and red light, what must be happening to other colours of light, like green and yellow?
Answer:
If plants are absorbing blue and red light other colors such as green and yellow are being reflected. For example, a green plant absorbs all colors of light and reflects green, which gives it its green color.
Plants absorb and use blue and red lights during the process of photosynthesis, and the electrons get excited which carry out other pathways. While the lights like green and yellow which are not absorbed are reflected which are visible to our eyes.
What is light absorption in plants?Plants contain a pigment in the chloroplast which is known as chlorophyll. This pigment is present in all the green plants, it is responsible for trapping the light energy which comes from the Sun or artificial source.
Chlorophyll absorbs the light of different wavelengths in the visible range of light. This is known as absorption spectrum of the plant. Rest of the other wavelengths of light are reflected from the plant body which are visible to the eyes.
The wavelengths of red and blue lights show maximum rate of photosynthesis in comparison to other lights.

1. Imagine that you collected a worker ant from an ant colony, and you found that it was positive for Wolbachia. Would you expect the ant queen from that colony to also be positive for Wolbachia
Answer:
Yes.
Explanation:
Yes, the ant queen from that colony to also be positive for Wolbachia because Wolbachia also cause infection in the ant queen. This bacteria lives in the cell of their host and cause infections. This bacteria specie is responsible for the reproductive and developmental changes in the invertebrates so we can conclude that Wolbachia also affect the ant queen of that colony.
The passage indicates that compared with other functions of coloration in plants, camouflage in plants has A) provided scientists with a deeper understanding of potential food sources. B) made use of a wider variety of distinctive shades of colors. C) proved to be a less effective defense against predators. D) been the subject of a smaller number of scientific investigations.
Question passage: This PASSAGE is adapted from “Rare Woodland Plant Uses‘Cryptic Coloration’ to Hide from Predators.” ©2009 byAmerican Journal of Botany, Inc.It is well known that some animal species usecamouflage to hide from predators. Individuals thatare able to blend in to their surroundings and avoidbeing eaten are able to survive longer, reproduce, andthus increase their fitness (pass along their genes tothe next generation) compared to those who standout more. This may seem like a good strategy, andfairly common in the animal kingdom, but who everheard of a plant doing the same thing?In plants, the use of coloration or pigmentation asa vital component of acquiring food (e.g.,photosynthesis) or as a means of attractingpollinators (e.g., flowers) has been well studied.However, variation in pigmentation as a means ofescaping predation has received little attention.Matthew Klooster from Harvard University andcolleagues empirically investigated whether the driedbracts (specialized leaves) on a rare woodland plant,Monotropsis odorata, might serve a similar purposeas the stripes on a tiger or the grey coloration of thewings of the peppered moth: namely, to hide.
The PASSAGE indicates that compared with other functions of coloration in plants, camouflage in plants has A) provided scientists with a deeper understanding of potential food sources. B) made use of a wider variety of distinctive shades of colors. C) proved to be a less effective defense against predators. D) been the subject of a smaller number of scientific investigations.
Answer: The correct option is C(proved to be a less effective defense against predators).
Explanation:
Adaptation is a means by which plants or animals modify their forms, structures, functions and behaviour in order to escape being harmed and survive in their environment. The special adaptations of organisms in a habitat enables them to live there successfully and reproduce. There are 3 types of adaptation which include:
--> structural adaptation,
--> adaptive coloration and
--> behavioural adaptations.
From the passage, the plant under study shows ADAPTIVE COLOURATION. Colour and colour pattern plays an important role in adaptations of plants. These occur due to the presence of pigments in cells of plants. Common pigments responsible for coloration in plants are:
--> chlorophyll: this gives green colour to plants that has chloroplasts in their cells.
--> Carotene and xanthophyll: this gives yellow to orange colour to plants that has chromoplasts in their cells.
From the passage, the use of coloration or pigmentation in the plant as a vital component of acquiring food (e.g.,photosynthesis) or as a means of attracting pollinators (e.g., flowers) has been well studied but it's use to escape from predation has received little attention. Therefore camouflage in plants has proved to be a less effective defense against predators.
King Penguins and Fur Seals King Penguins and Fur Seals are both designed for swimming, and thus are very clumsy on land. With that in mind, answer these questions: Why do the penguins come onto land at all
Answer:
The correct answer is - chicks will not be able to survive in water.
Explanation:
Penguins spend the majority of their life in the water and for mating and moult they move to land and also lay their eggs on land. The wings or flippers of the chicks of these penguins are not as efficient as the wings of the adult penguins.
This makes it tough to survive on the waters for the chicks of penguins. Therefore they move to land even they are very clumsy on the land. The mating, molt and raising the chicks to few weeks are the prime reason.

Answer:
What Darwin Never Knew”, is a stunning time line that details the theory of evolution formed by Charles Darwin, and the recent advancements made that answers some of the questions he simply could not. Darwin 's theory explained why today there are 9,000 kinds of birds, 350,000 kinds of beetles, 28,000 kinds of fish, and at least 2 million kinds of living species and counting. Darwin figured out that all species are connected, and he also realized that species evolved and adapted, but he did not know how. Darwin made a five year voyage on The HMS Beagle that would change his life, and all life as a matter of fact, forever.
When one glucose molecule travels through the glycolysis processes, four molecules of ATP are generated. Is it accurate to suggest that glycolysis produces two ATP molecules?
Answer:
No
Explanation:
Technically, this is inaccurate. To say that glycolysis produces two ATP molecules strays from the input of ATP needed. Overall, 4 ATP molecules are produced during glycolysis. However, there is an input of 2 ATP molecules at the beginning. Therefore, the correct statement would be that glycolysis produces 2 net ATP molecules, not that glycolysis produces 2 ATP molecules. (The word net makes a big difference!!).

The antibiotic susceptibility testing result of Staphylococcus aureus showed absence of growth on the zones of penicillin, ampicillin, tetracycline, chloramphenicol disk. Interpret the result.
Answer:
See Explanation
Explanation:
We define antibiotic susceptibility testing as an evaluation of the ability of antibiotics to inhibit bacterial growth. This test is necessary because certain bacteria may have developed resistance to certain antibiotics.
Hence, if the antibiotic susceptibility testing result of Staphylococcus aureus showed absence of growth on the zones of penicillin, ampicillin, tetracycline and chloramphenicol disk, then it implies that these antibiotics are all largely effective against Staphylococcus aureus and could be used for treatment of Staphylococcus aureus infection.
