According to Newton’s second law of motion, applied force is directly proportional to the rate of change of momentum.
Momentum is basically the product of mass (m) and speed (v) of an object.
To Newton, this simply meant that if he pushes his triangular prism its speed will vary. Why speed and not mass? Because mass is constant, duh! At least that’s what everyone believed.
So far so good?
Now I ask you a question
What if I go on applying some force on an object?
Using Newton’s second law, the answer is: it’s speed goes on increasing;
which is absolutely correct!
And this result did not hurt anyone until Special Relativity came onto the main stage of Physics:
You see, the problem here is that according to Special Relativity the speed of light is the universal speed limit. No object can ever travel faster than light.
So what do we do now? We know for sure that Newton’s second law is correct.
As we know that force changes momentum: a product of mass and velocity. If velocity cannot be increased beyond “c” let’s increase the mass.
I’ll introduce something called the Lorentz factor here:
γ=11−v2c2√
applying this factor to mass:
m=m01−v2c2√
m0: is the rest mass
m = mass when the object is moving at velocity v
For v<<<c, the denominator is approximately equal to 1. However, if the speed starts getting really close to the speed of light (let's say 0.9c) the value of m gets huge.
Simply put, if the velocity increases, the object gets heavier thus making it difficult to increase its speed further.
And so, the object is never able to achieve the speed of light.

The artichoke is a huge, thistle-like perennial plant of the aster family (Asteraceae), often known as the globe artichoke or the French artichoke, and its flower buds are farmed for their gastronomic qualities.
The young bloom bud of a thistle is an artichoke. It is considered a vegetable in cuisine and is consumed as such. The plant, an aster, is plucked for its buds rather than its flowers. It takes some effort to get to the edible sections of an artichoke, which makes it a difficult vegetable to prepare.
What are some examples of UCS, UCR, and CS?
The chemotherapy medications are the unconditioned stimulus (UCS) in this scenario, the vomiting is the unconditioned response (UCR), and the doctor's office is the conditioned stimulus (CS) after being matched with the UCS and UCR.

II. The chemical formula is C36H62O31
III. The monomers of glucose were joined via hydrolysis
IV. The monomers of glucose were joined via dehydration synthesis
Answers
Answer:
Statement 'IV' is correct
Explanation:
Glucose molecules are joined together through condenstation/ dehydration (loss of water) reactions.
The statement that is true with regard to a polymer of 6 glucose molecules is as follows:
The monomers of glucose were joined via dehydration synthesis.Thus, the correct option for this question is D.
What is Glucose?Glucose may be defined as a type of simple sugar known as monosaccharides. It bears a chemical formula [tex]C_6H_1_2O_6[/tex]. It is considered the main type of sugar in the blood and is the major source of energy for the body's cells.
Dehydration synthesis involves the reaction between two or more molecules of glucose with the continuous liberation or loss of water molecules. The chemical formula of glucose remains the same when there are six or more polymers that take place, the chemical formula never changes.
Therefore, the correct option for this question is D.

DNA in eukaryotic cells lie within the nucleus. This DNA has a membrane protecting it from the outside. This means that the virus would have a harder time getting to the DNA to insert its DNA in a Eukaryotic Cell.

Unlike eukaryotic cells, prokaryotic cells do not have a nucleus.
What are prokaryotic cells and eukaryotic cells?Prokaryotes are organisms whose cells lack a nucleus and other organelles. Eukaryotic cells have a membrane-bound nucleus.
Eukaryotic cells have a separate organelle named nucleus (plural: nuclei) which is a double membranous structure meant for the storage of genetic material i.e. chromosomes (DNA). Prokaryotes on the other hand have an irregularly shaped structure named nucleoid instead of nucleus. All the genetic material of the prokaryotes is within the nucleoid. Unlike nucleus, nucleoid does not have any nuclear membrane & it is spread in the cytosol freely.
Hence, option D is the correct answer.
