Answer:

Option B, a generation

Explanation:

A pedigree is a tree diagram that represents the relationships between different individuals based on certain facts and medical(genetic evolutionary) histories. Basically , the branches of the tree represents the generations which allows the researcher understand how certain genetic characteristics or traits are transmitted with in a family

Such as transmission of any genetic diseases from one generation to the other.

Hence, option B is correct

What is a major difference between facilitated diffusion and active transport?

xenn [34]

Answer:

The correct option is<em> A. Active transport moves substances against the concentration gradient.</em>

Explanation:

Active transport can be described as a transport mechanism in which molecules tend to move against the concentration gradient i.e from an area of lower concentration to an area of higher concentration. Energy is needed for this process to occur.

Facilitated diffusion can be described as a phenomenon is which molecules move along the concentration gradient i.e from a higher concentration to a lower concentration with the help of trans- membrane integral proteins

A 100 kg box is initially at rest on a level surface. One 10 N force acts on the box , directed toward the right. A second 10 N

Paladinen [302]

Answer:

The box will not move because balanced forces are acting on it.

Explanation:

According to Newton's first law of motion, an object will remain in its state of rest or motion along a straight line unless acted upon by an unbalanced force.

An unbalanced force is an individual force acting on any side of an object which is not balanced by a force of equal magnitude acting in the opposite direction.

From the image, two forces of equal magnitude of 10 N are pulling the 100 kg box in opposite directions. Since the two forces, 10 N each are pulling the object in opposite directions, they are balanced forces. Therefore, the box will not move because balanced forces are acting on it.
