The image shows the femur bone of the leg and part of skull . Identify the various bone markings in the image
Answer: A fossa is a shadow depression in the bones of the skull. A firearm is a hole in a bone. In the image of the skull, the hole at the base is the opening through which the spinal cord passes. A tubercle is a small nodualr projection, which is visible in the image of the femur bone of the leg.
Explanation: Edmentum
There are two species of freshwater shrimp that are introduced to a pond. The first species, Caridina cantonensis, is brightly colored with red and white stripes. The second species, Caridina multidentata, is more mottled drab in coloration. Fish have an easier time finding and eating Caridina cantonensis due to their bright colors. When each of these species reproduce they produce about 100 offspring, but only 30% Caridina cantonensis offspring survive to reproductive age, while 75% Caridina multidentata offspring survive to reproductive age.
A. In this situation what is natural selection selecting for?
B. In this situation what is natural selection selecting against?
C. How do you predict this population will evolve?
D. Identify how each of the listed conditions from the above scenario that influence natural selection. Population must have variation. Some variations are favorable More offspring are produced than survive Those that survive have favorable traits Differential reproductive success
Answer:
A. Colour of the freshwater shrimp
B. Predator fish problem
C. Based on the number of offsprings that has survived
D. Differential reproductive success
Explanation:
A. The freshwater shrimp species C. cantonensis is brightly coloured which is easy to find by fish whereas C. multidentata is mottled drab in colour which can hide in the environment. Therefore the natural selection will select for the mottled drab of the shrimp.
B. The mottled drab colour of the shrimp will be selected against the predator species which feeds on the shrimp population as the predator species can find the brightly coloured species easily but the mottled drab colour will not be found.
C. The population is evolving can be identified based on the number of population found in that area as 75% of C. multidentata species reach reproductive stage while only 30% of C. cantonensis reach the reproductive rate.
D. The condition will be known as Differential reproductive success.

Calculate pH a decrease of one unit on the pH scale means a solution is ten times more acidic. a decrease of two units means the solution is 100 times more acidic. how much more acidic is acid precipitation( pH = 4.0) than pure water (PH= 7.0 )
Answer:
Each unit of decrease has an exponential increase. So if you are looking at an item that has a Ph of 4 and water has a Ph of 7 —-that means it is 10 to the 3rd power more acidic or 1000 times more acidic than water.
Explanation:
A decrease of one unit on the pH scale means a solution is ten times more acidic; a decrease of two units means the solution is 100 times more acidic; so pH 4 means the solution is thousands of times more acidic than normal water.
What is the effect of pH on the cell?The pH scale shows the pH from 1 to 14, where pH 7 is taken as neutral, below which the solution is more acidic, and above which the solution is more basic. The pH has an important role in the organism as it regulates the blood and maintains enzymatic function.
Hence, a decrease of one unit on the pH scale means a solution is ten times more acidic; a decrease of two units means the solution is 100 times more acidic; so pH 4 means the solution is thousands of times more acidic than normal water.

Yersinia pestis, the organism that causes the bubonic plague, led to the deaths of approximately 75 million people is the 1300's. This was known as the Black Death. Which type of organism caused the bubonic plague?
Answer:
Yersinia pests
Explanation:
it is a bacterium. its vectors is infected flea from an animal. The plague can also results from contact with contaminated fluid from dead infected animal from bubonic plague.
when the flea bites, the bacterium enters the blood stream and through the lymphatic systems it finds it way into the lymph nodes of the armpit and pubic region.
it localized in the nodes leading to swelling, enlarged nodes-buboe, with painful sensation.
chills, high fever, seizures, are some of the symptoms.
proper hygiene is the best preventive methods.
Which resource is a non-renewable resources? A.fresh water B.Maple trees C.Solar Energy B.Precious metal
Answer:
Precious Metal, bc nature will not renew it and there's just a limited amount on any given planet.
Technically true for the sum of all water on the planet too, but fresh water gets renewed by cyclical processes in nature.
and solar energy (and trees for that matter) are also just renewed from our earthly perspective of space and time. stars do nuclear fusion, and this is a one-way process, single use basically.
so nothing is truly renewable, but we can't use up some things and get new supply for any given time, at least in time spans we can grasp.

Choose the true statements about amyloid fibrils. 3 options are correct:a) An amyloid fibril typically forms from aggregates of misfolded peptides resulting from frameshift mutations. b) An amyloid fibril is stabilized by hydrophobic interactions between aromatic residues. c) Soluble proteins that misfold and form amyloid fibrils become insoluble. d) Because most newly synthesized proteins fold correctly, the accumulation of misfolded proteins (or fragments) tends to occur slowly, thus explaining the slow onset of disease. e) Proteins that convert to an amyloid fibril structure tend to have low solubility in their native form.
Answer:
The correct answers are: b) "An amyloid fibril is stabilized by hydrophobic interactions between aromatic residues", c) "Soluble proteins that misfold and form amyloid fibrils become insoluble", and d) "Because most newly synthesized proteins fold correctly, the accumulation of misfolded proteins (or fragments) tends to occur slowly, thus explaining the slow onset of disease".
Explanation:
Amyloid fibrils are protein aggregates that can cause pathological conditions, for instance, they are found in brain tissue in people with Alzheimer disease. This disease, and other relates diseases, have a slow onset because most newly synthesized proteins fold correctly and the protein aggregates are made up misfolded proteins. This newly synthesized proteins are soluble, but once the proteins are misfolded, they form amyloid fibrils that are insoluble. The amyloid fibrils are stabilized by hydrophobic interactions between aromatic residues, which are formed within the complex of insoluble misfolded proteins.

Thymidine is a nucleoside made up of pentose sugar, pyrimidine base tymine and deoxyribose, it is one of the the four nucleoside found in exclusively DNA as well as T-loop of tRNA.
Tetrahydrofolate also known as tetrahydrofolic acid can be described as part of folic acid that function as a coenzyme which aid metabolic reactions that includes nucleic acid and amino acids. It is also reffered to as one-carbon metabolism, and it's oone-carbon mechanism is associated to the histidine, serine of amino acid.

Will change in ocean salinity cause a change in climate overall? Why or why not?
Answer:
Yes
Explanation:
Ocean play very important role in climate change. Change in the salinity of ocean definitely going to affect climate because changes in salinity have effect on water density.
Change in density allows changes in the movement of seawater and shift in climate pattern. if salinity will increase, water will become heavier and sink deep in ocean, which joins the currents that circulate all over the world. These currents affects the transport of heat and affect the rainfall pattern, example of such currents is gulf stream.
So, stable salt densities or salinity in the oceans keep the earth’s climate in balance.
