Answer:
c
Explanation:
There is a ball-and-socket joint in the hip area of the body. So, the correct option is C.
What is Ball-and-socket joint?The hip is home to the ball and socket joint. It is situated where the pelvic bone and femur (the thigh bone) meet. An example of a ball and socket joint is one in which one bone exactly resembles a ball and another bone precisely resembles a hollow or socket into which the first bone would fit.
This facilitates the bone's mobility in all planes. As a result, the hip has a ball and socket joint and can move in all directions. When compared to other joints, which are found in the fingers, knees, elbows, and toes, ball-and-socket joints, such as those in the shoulder and hip, permit only bending and straightening motions.
Therefore, the correct option is C.

How would the coils in the middle of the diagram change
to show a longitudinal wave with higher energy?
They would be farther apart.
They would be closer together.
O They would be shaped like a hill.
O They would be shaped like a valley.
Answer:
They would be shaped like a hill.
Explanation:
A longitudinal wave with higher energy have greater amplitude. Amplitude is the distance between the crust and trough of the wave. Crust is the upper part of the wave while trough is the lower part of the wave. If the distance between crust and trough of the wave is higher so the amplitude is also greater and we can say that the wave contains high amount of energy and vice versa. The shape of the wave just like a hill.

John complains of severe pain in the region of his left cheek which seems to increase when he chews on his food. A tense swelling is seen just anterior to his left ear. Which of the following structures do you think is the most likely cause of the problem?
1) submandibular salivary gland2) lingual tonsil3) palatine tonsil4) parotid salivary gland5) sublingual salivary gland
Answer:
Parotid salivary gland.
Explanation:
John's parotid salivary gland is the major cause of the problem
Parotid salivary gland is the largest of the salivary gland. Parotid salivary gland is found in the mouth, the upper part of the cheek and part of the ear.
This gland help to chew and empty saliva into the mouth.
A viral infection like flu, mumps can cause swelling of the parotid salivary gland.
Other symptoms include ;
Tender , lump cheeks.
Swollen cheeks
Difficulty in opening the mouth and swallowing food.
Pain in the left ear
Fever , chills and general weakness and so on.
Treatment of this depend on the type of infection, drinking hot water with lemon juice can help can help stimulate saliva.
Answer:
parotid salivary gland-parotitis.
Explanation:
This is located in front of and just below each ear.When the duct which drains this gland it blocked,drainage of saliva is prevented, and therefore lack of drainage leads to pain.
its inflammation is due primarily to bacterial infection,among other factors which are HIV,diabetes,etc.
Antibiotic intake is the most effective way of treatment.
In addition,the treatment is based on saliva stimulation to unblock the drainage. Therefore lemon intake either as raw or with water is ideal way.
When glycogen phosphorylase is phosphorylated Group of answer choices its activity decreases. its activity increases. its activity is unaffected. none of these because that enzyme doesn't get phosphorylated.
Answer:
The correct answer is that its activity increases.
Explanation:
Glycogen phosphorylase comes under the category of phosphorylase enzymes. The mentioned enzyme catalyzes the rate-limiting step in the process of glycogenolysis within the animals. The sequential phosphorolysis of glycogen to discharge glucose-1-phosphate is catalyzed by the enzyme glycogen phosphorylase. Therefore, glycogen phosphorylase plays an essential part in the use of liver and muscle reserves of glycogen. After undergoing phosphorylation, the activity of the enzyme increases.

Why is the word "translation" used for protein production? Protein production is the process of:________.
Answer:
Answered below
Explanation:
Translation is the actual process of protein synthesis and it occurs in the cytoplasmic ribosomes. Protein production or protein synthesis is the process in which cells make proteins. This process occurs in two stages called transcription and translation.
Transcription involves the transfer of genetic information in the deoxyribonucleic acid to the messenger ribonucleic acid in the nucleus through the process of initiation, elongation and termination. The messenger ribonucleic acid is processed and carries the information to a ribosome in the cytoplasm where protein production takes place through translation.
During translation, the instructions in the messenger ribonucleic acid are read and transfer ribonucleic acids ensure the correct sequencing of amino acids in the ribosomes. The rRNA is involved in the bonding of the base pairs to produce a polypeptide chain which is a unit of a finished protein.
Answer:
The word translation is use for protein production because it is the process of translating RNA sequence of bases.and thereby producing sequence of encoded amino acids from the RNA
sequence which is a consist of polypeptide chain during protein synthesis.
Protein production is the process of synthesising protein.
Explanation:
Translation is a process that occur in the RIBOSOMES or endoplasmic recticulum after transcription of RNA and it is the process where genetic code in the messenger RNA is decided or translated to a sequence of amino acid.
Protein synthesis is processs by which cells produce protein which occur in the RIBOSOMES.
Protein synthesis occurs in two stages which are Transcription and translation.
Transcription is the process whereby genetic instructions or materials in DNA are transmitted to messenger RNA in the nucleus.
It involves initiation, enlongation and termination.

In a hydropower station, water stored in dams is allowed to fall with force to make a turbine move. The turbine moves and produces electricity. In the diagram, identify the stages of transformation of energy in the hydropower station. Please help!!
Answer:
Stored water - gravitational energy
Water fall - kinetic energy
Turbine - kinetic energy
Powerlines - electric energy
Explanation:
Dams are used to store or hold water for hydroelectric power plants. This stored water which has gravitational energy is a form of potential energy.
When the water is left to fall and run fast through the turbine, the gravitational energy is transformed into kinetic energy which makes the turbine to spin.
As the turbine spins, kinetic energy that is produced also powers the shaft of the engine in the electric generator, which produces electricuty.
Kinetic energy is transformed to electric energy and transmitted along powerlines.
*See attachment below for labelled energy that is being transformed at several points.

These modulation factors are thought to possibly interact with the genetic predisposition for obesity through epigenetic mechanisms.
A farmer plants Bt cotton that is genetically modified to produce its own insecticide. Of the cotton bollworms feeding on these Bt plants, only 8% survive unless they have at least one copy of the dominant resistance allele R that confers resistance to the Bt insecticide. When the farmer first plants Bt cotton, the frequency of the R allele in the cotton bollworm population is 0.4. What will the frequency of the resistance allele be after one generation of cotton bollworms fed on Bt cotton
Answer:
0.6
Explanation:
According to hardy-weinberg principle,
P2+2pq+q2=1
P+q=1
q=1-p
Given that Allele R frequency is 0.4
and p represent the dominant allele
P=0.4
P2=0.4^2 = 0.16 for genotypic frequency
Since p+q=1
q=1-p
where q stands for recessive allele r frequency and q2 stands for genotypic frequency for allele r
q= 1-0.4= 0.6
q2=0.6 ^2
q2=0.36
Hardy-Weinberg principle states that are used to calculate the genetic variation of a population at equilibrium.
The frequency of the resistance allele in the cotton bollworm is 0.6.
Hardy-Weinberg equation can be given as:
P² + 2PQ + Q² = 1
where,
P = dominant allele (R)
Q = recessive allele (r)
Frequency of R allele = 0.4
From the equation:
P + Q = 1
or,
Q = P - 1
Genetic frequency of the R allele = P² = 0.4 x 0.4 = 0.16
Substituting the values:
Q = 1 - 0.4
Q = 0.6
Q² = 0.36
Thus, the frequency of the resistance allele will be 0.6.
