Answer:
a) Ribosomes
b) Please find the justification for the answer in (a) below.
Explanation:
According to this question, Hepatitis C is a virus that causes liver disease by attacking the liver. However, a REDUCTION IN ALBUMIN, which is a protein that regulates oncotic pressure of blood in humans- a process necessary for the regulation of fluids in vessels of the body and tissue repair, has been found to have to do with liver disease.
Since ALBUMIN is a protein produced by the liver, which when diseased causes a reduction to the blood-albumin level, the organelle in liver cells that is most likely being affected by hepatitis C is the RIBOSOME. This is because the RIBOSOME is the organelle/site for PROTEIN SYNTHESIS in any cell. Hence, the ribosome organelle of the liver cells are responsible for synthesis of Albumin protein.
Hence, a diseased liver due to attack by Hepatitis C virus means an attack on the RIBOSOMES of the liver cells producing the protein.
1. Kinetic Energy is the energy of mass in motion. In a rescue mission, kinetic energy is the most used energy to carry out the rescue operation successfully.Anything that moves and has a role in rescuing the victims can be termed as the kinetic energy involved in rescue team missions
2. You may be saving someone from a rock slide, where the rocks will fall at any time, before they fall they have potential energy.
Answer:
The right answer to this question is option A) island forms and mainland forms descended from common ancestors.
It's known in science that a long time ago, all the continents were only one, united all together in a bigger one. This can be observed by the way every continent can fit another one.
A proof of that too, is evolution, when we find organisms in an island that share some characteristics with organisms from another island, that can mean some things, they come from the same place, or these islands share characteristics that lead these organisms to be this way through evolution.
Answer:
The type of natural selection that occur when intermediate phenotype is favored is called STABILIZING SELECTION.
Explanation:
There are 3 major types of natural selection, these are: stabilizing, directional and diversifying selection.
A stabilizing selection is said to occur when natural selection favors average phenotype by selecting against extreme variations. Stabilizing selection usually leads to decrease in genetic variation of the population concerned.
A good example of stabilizing selection is that of snakes, which have deep green color that blend completely with their environment. This set of snakes will escape from predators more than others in the population, which have color that slightly differ from deep green and which do not blend very well with the environment. Those snakes, whose colour do not blend very well with their environment will get killed more easily by the predators and with time will become extinct while those with colour that blend with the enviroment will survive and produce more offspring.
The extinction of snakes from the population will lead to decrease in genetic variation.
<u>ANSWER:</u>
The correct option is B- Qualitative.
<u>EXPLANATION:</u>
When the growth of corn has to be recorded, the quality of the corn grown in different soils needs to be recorded. Qualitative methods are best used to classify quality of anything.
Qualitative data basically is non-numerical data which in the case of corns can be the length of the corn plant, the sweetness of the corn kernel or the hardness or softness of the corn. This data cannot be recorded using numerical values and so other methods of data recording cannot be used.
