Which of the following statements concerning ribosomes is true?
A. Several ribosomes are often attached to and translating the same MRNA.
B. Ribosomes join amino acids together to form a polypeptide.
C. Ribosomes have one binding site for MRNA and three binding sites for 1RNA molecules.
D. Ribosomes are the organelles responsible for protein synthesis.
E. All of the above statements are true.
Answer:
E. All of the above statements are
Explanation:
Ribosomes are organelles found free floating in the cytoplasm or attached to endoplasmic reticulum (RER). They are the site of protein synthesis in a cell. Ribosomes initiate the translation process by binding to the mRNA molecule using their mRNA binding site. Several ribosomes called POLYSOMES are often attached to and translating the same MRNA molecule.
A ribosome contains four (4) binding sites; one for the mRNA and three (P-site, A-site and E-site) for tRNA, which are small RNA molecules that carry and add amino acid to the growing polypeptide chain during the process. In a nutshell, the ribosome via the aid of tRNA is responsible for joining amino acids together to form a polypeptide chain (future protein).
Ribosomes are complicated macro molecules composed up of nucleic acids and proteins. They are important as they perform a major role in protein assembly and transportation.
The correct answer is:
Option E. All of the above statements is true.
The explanation for the above option is:
The ribosome is located either free or is connected to the endoplasmic reticulum(RER).Ribosomes assist in the translation of the information from mRNA.Polysomes are numerous ribosomes connected to a single mRNA molecule.Ribosomes have one binding position for mRNA and three binding positions for tRNA molecules.The three binding sites for tRNA is (A- site) amino acyl site, (P-site) peptidyl site and (E site) the exit site.Ribosome assembles amino acids to form a polypeptide chain. These polypeptides get transported to the cytoplasm.Therefore all the above statements are true for ribosomes.

Water has the property of having a high specific heat. This trait has a great influence on maintaining homeostasis within the body. Which of the following accurately explains what it means to have a high specific heat
Answer:
We can write the specific heat as:
C = (dU/dT)
Where C is the specific heat, U is the internal energy and T is the temperature.
This is:
"How much does change the internal energy when the temperature changes".
Having a high specific heat (and positive) means that for every little increase in the temperature we will have a large change in the internal energy.
What does this mean?
Think in the inverse way:
A larger specific heat means that we need a large amount of heat (the heat is energy) to change a little the temperature.
Then this is good, because even when receiving a lot of heat, the body temperature will remain about the same.

Nicholas has been biting his nails since he was a kid. He wants to break the habit so he puts bitter-tasting nail polish on his left hand and leaves his right hand without polish. After 3 days he notices his nails on his left hand have grown but he continued to bite his right-hand nails.
A. Independent Variable=
B. Dependent Variable=
C. Control=
Answer:
Independent: Putting the nail polish
Dependent: nail growth
Control: right hand, without polish
The experiments are known to have various variables. In Nicholas's case, nail polish is an independent variable, nail growth is a dependent, and right nails without polish are a control.
What are independent variables?Independent variables are defined as the test variables that in an experiment are not constant but are kept varied and manipulative causing various effects on the result of the hypothesis. Putting the bitter nail polish on the nails of the left hand is a test variable.
The dependent variable (outcome variables) along with independent results in cause and effect and are conditional on the independent factors. The length of nails is dependent as it is affected by the nail-biting.
On the other hand, the control variables are constant in that the factors are limited so that they do not interfere with other factors that affect the outcome. Fingernails on the right hand with no polish are controlled.
Therefore, nail polish is an independent variable.

In aquatic ecosystems, phytoplankton and other photosynthetic organisms appear in the upper layer of the water, but not deeper layers. Which statement explains this distribution?
ANSWER :
The deeper layers are too dark for photosynthesis to occur.
Explanation:
Photosynthesis is a unique process to autotophic organisms. It involves the use of light energy from the sun to manufacture organic molecules (food). As the phenomenon implies i.e. PHOTO - LiGHT, light is an unnegotiable requirement for photosynthesis to take place. Autotrophs are able to perform this process because they contain pigments (Chlorophyll) that can trap energy from sunlight.
In an aquatic ecosystem, phytoplanktons and other photosynthetic organisms like aquatic plants are the autotophic organisms. They are found in the upper layer of the water so that they can reach light from the sun. The light from the sun cannot travel deep down the water making the deep parts of the ocean be deprived of light.
This is the reason why photosynthetic organisms cannot be found in the deep parts of the water as they will be unable to have access to the light from the sun in order to perform photosynthesis.

If you removed the lens from an eye and looked through it at an upright tree, how would the tree appear?
upright
upside down
the top of the tree would be pointing to the left
the top of the tree would be pointing to the right
If you removed the lens from an eye and looked through it at an upright tree, the tree appear upside down. Thus, the correct option for this question is B.
What is the function of the lens?The function of the lens in the eyes is to focus light rays onto the retina. Then the retina converts this light into electrical signals which send messages to your brain and creates the image that you observe.
The lens of the eye is the translucent biconvex structure that dangled behind the Iris of the eye. If you eliminate the lens from an eye and looked through it at an upright tree, then the perception of light is not made and cannot stimulate electrical signals by the retina, and the tree will appear upside down or an inverted image is formed.
Therefore, the tree will appear upside down, if you removed the lens from an eye and looked through it at an upright tree. Thus, the correct option for this question is B.

Explanation:
A bar graph
You want to show that there is no connection between one species and another.
The line graph will do exactly the opposite. It will imply that the line joining 2 points gives some connection between one point and the next point.
The Pie chart is usually used to compare one number size with a another, like the total number of Covus 19 by state each state close to the other. It is not a good choice because California (for example) might have the most number of cases of the virus but it also has the largest population.
