Answer:
D. 4 times as great
Explanation:
The inertia of an object is the resistance offered by the object to change in its motion or position.
Then concept of inertia is obtained from Newton's first law of motion which states that an object which is not subjected to any net external force will remain its position of rest or constant velocity of motion until some net external force acts on it. The object at rest will then start to move whereas the object moving at constant velocity will experience a change in its speed or direction of motion.
This reluctance to change position is greater, the more massive an object is as well as the higher the speed of motion of the object. Thus, inertia is directly proportional to the mass of the object as well to the velocity of an object in motion.
From Newton's first law, inertia can be calculated as the force to be overcome to mobile an object, i.e. Inertia = F = ma
Where m is mass of object, a = acceleration of the object.
Objects on the earth's surface experience a constant acceleration, g.
Thus for a 1 kg mass, Inertia = 1 × g
For a 4 kg mass, inertia = 4 × g
The inertia of a 4 kg mass is four times as great as a 1 kg mass.
Biogeographic isolation refers to the separation of the members of the similar species, or a group of organisms, which breed and generate offspring that can further give rise to young ones.
The separation can be achieved by the geographical forces like oceans, rivers, and mountains, and by the biological forces, like hunting times, and spring or fall mating.
Answer:
The correct answer is - 75% or 3/4.
Explanation:
In the given question, there is a cross between III-6 and III-7 that produced two double eyes monsters and expected one more. As given in the image that the A or single eye is dominant over the a or double eye then both parents must be heterozygous as they produced double eye offspring (aa) and they do have only one eye.
then chances of single eye offspring would be -
cross: Aa and Aa
gametes: A, a and A, a
Punnett square:
A a
A AA Aa
a Aa aa
so there are 75% chances to have a single eye and 25% chances for a double eye.
Answer: diffusion
Explanation:
Diffusion is the over all movement of molecules from one region where it is in high concentration to another another region where it is in lower concentration.
This movement continues until the concentration of both regions are equal. Smaller non polar molecules are able to diffuse through the lipid bilayer of the membrane .
Movement through the membrane is dependent on the concentration gradient, that is the difference in concentration between the two areas.
It is also dependent on the size of the molecule
