New algorithms for estimating chlorophyll-a in the Spanish waters of the Western Mediterranean Sea from multiplatform imagery This manuscript proposes a set of multi-sensor chlorophyll-a empirical algorithms for improving current estimates of chlorophyll-a concentration in two distinct regions in the Mediterranean Sea.

Many studies in the area of cancer research are opening up new possibilities for cures and prevention measures.  One area of research is directed at the effects that chlorophyll may have on cancer cells within the human body.  Research is being conducted to investigate whether chlorophyll has important cancer fighting factors that may play a role in the destruction of cancer cells or whether it is an effective preventive agent.  

Daily supplements of the chlorophyll derivative, chlorophyllin (CHL) can provide a way to prevent cancer by reducing DNA damage  (Arbogast, 1995).   The chlorophyllin copper complex (CHL) is a water-soluble version of chlorophyll and is a semi-synthetic prepared substance.  CHL is the most common chlorophyll derivative used for cancer related studies  (Chernomorsky, 1999).  Most research was done using chlorophyllin because chlorophyll is chemically modified to chlorophyllin in the body during digestion. Chlorophyllin given in amounts to that of chlorophyll were equally effective in the studies  (Sarkar, 1994).  CHL can be added to the diet very easily and may be safe and useful for effective prevention of cancer  (Arbogast, 1995).

Answer:

It is quite difficult to picture a pseudoscientist—really picture him or her over the course of a day, a year, or a whole career. What kind or research does he or she actually do, what differentiates him or her from a carpenter, or a historian, or a working scientist? In short, what do such people think they are up to?

… it is a significant point for reflection that all individuals who have been called “pseudoscientists” have considered themselves to be “scientists”, with no prefix.

The answer might surprise you. When they find time after the obligation of supporting themselves, they read papers in specific areas, propose theories, gather data, write articles, and, maybe, publish them. What they imagine they are doing is, in a word, “science”. They might be wrong about that—many of us hold incorrect judgments about the true nature of our activities—but surely it is a significant point for reflection that all individuals who have been called “pseudoscientists” have considered themselves to be “scientists”, with no prefix.

Answer:

Explanation:

A girl can increase the total energy of this system by standing on a table while swinging the yo-yo. Thus, the correct option is B.

Yo-yo may be defined as a type of toy that consists of a pair of joined discs with a deep furrow between them in which thread is attached and wound.

By reversing the direction of the swing, swinging the yo-yo at a lower speed, and sitting on the ground while swinging the yo-yo decrease the total energy of the system. This is because the system does not have the momentum that is required to increase its overall energy.

Therefore, a girl can increase the total energy of this system by standing on a table while swinging the yo-yo. Thus, the correct option is B.

Answer:

The law of segregation states that the two alleles of a single trait will separate randomly, meaning that there is a 50% either allele will end up in either gamete. This has to do with 1 gene. The law of independent assortment states that the allele of one gene separates independently of an allele of another gene.

The force is by putting the two same objects on both sides and the motion is the scale

The force is by putting the two same objects on both sides and the motion is the scale.

In physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull.

The normal force acts in a direction normal to the surface interaction between objects. Friction is a force that opposes motion on surfaces. Other examples of non-fundamental forces include the elastic force, tension.

Force is the fundamental result of an interaction between two objects, while power is an expression of energy consumed over time (work), of which force is an element.

The applied force and the force of friction are balanced in the picture because of which the person is standing still. Therefore option (A) is correct.

A change in the force that is applied to an item with mass will cause that thing to move at a different speed. A body's state of rest or motion can be altered by the application of an external agent known as force. It is significant in both magnitude and direction.

The term "frictional force" refers to the force that is produced when two surfaces come into contact with one another and then slide against one another. A few factors that affect the force of friction are as follows: These forces are primarily influenced by the surface texture as well as the amount of force that is drawing them closer together.
