The diagram below shows two locations where fossils of Mesosaurus have been found. Mesosaurus was a fresh water reptile that existed on Earth about 250 million years ago. Which statement best explains why these freshwater Mesosaurus fossils are found today in some rock layers in both South America and Africa?
Answers
Answer:
they was together at one point but because of the plants under the Continent they were separated and moved
The statement which best explains why these freshwater Mesosaurus fossils are found today in some rock layers in both South America and Africa is The remains of the Mesosaurus were carried across by predators.
Where have Mesosaurus fossils been found?
Remains of Mesosaurus, a freshwater crocodile-like reptile that lived during the early Permian (between 286 and 258 million years ago), are found solely in Southern Africa and Eastern South America. It would have been physiologically impossible for Mesosaurus to swim between the continents.
How do we know Mesosaurus was freshwater?For years, mesosaurs have been considered aquatic (water-living) animals, because they have several characteristics of species that are adapted to aquatic life, like webbed hands and feet and the presence of thickened and compact bones.

The antibiotic susceptibility testing result of Staphylococcus aureus showed absence of growth on the zones of penicillin, ampicillin, tetracycline, chloramphenicol disk. Interpret the result.
Answers
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.

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°
Answers
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°

is 0.5 mm². The area of particle
1 is how many times as big as
the area of particle 2?
Answers
Answer:
The correct answer is - 5 times
Explanation:
Given:
area of P1 = 2.5
area of P2 = 0.5
Solution:
Let assume:
area of P1 is x times of the area of P2
then the equation would be:
=> 2.5 = x*0.5
=> 2.5/0.5 = x
=> 5 = x
Thus, area of P1 is 5 times to the area of P2
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.
Answers
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.

a. Antibody, complement C5-9
b. Circulating immune complexes; complement C5a, neutrophils
c. Cytotoxic T lymphocytes
d. IgE, mast cells, histamine, cytokines
e. Lymphocytes, cytokines, macrophages
Answers
Answer:
The correct answer is: E) Lymphocytes, cytokines, macrophages.
Explanation:
Given the symptoms and how much time they took to appear, the 14-year-old boy seems to be having delayed-type hypersensitivity (also called Type 4 hypersensitivity), causing a reaction called Contact Dermatitis. Type 4 is the only type of hypersensitivity that does not require the intervening of an antibody to occur as it happens because of hapten-specific T cells that will generate inflammation and the tissue damage that is usually accompanied by it.
Delayed-type hypersensitivity is characterized for happening at least 48 hours after the contact with the antigen, and will involve activated T lymphocytes (specifically CD4+ Th1), which will secrete cytokines (most importantly Interferon Gamma and IL-2) thus attracting macrophages to the tissue to phagocyte the antigen and produce inflammation.

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?
Answers
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!!).
