A. They lean towards the light.
Answer:
Magenta paints
Explanation:
Magenta paints absorb green light. Cyan paints absorb red light. Yellow paints absorb blue light.
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.
<h2>
Answer:</h2>
Option A) Dark moths had a survival disadvantage in industrial Dorset. is wrong and all other options are correct
<h2>
Explanation:</h2>
Dr. Henry Bernard Davis Kettlewell was a the scientist who demonstrated that if natural selection caused the change in the moth population, the following must be true:
- Heavily polluted forests will have mostly dark peppered moths.
- The majority of light peppered moth will be present in clean forests.
- The birds will eat dark moths present on light trees more likely than light moths. And visa versa.
- The dark moths present in polluted forests will live longer, but in case of clean forest light peppered moth will live longer than dark moth.
Result: option A) "Dark moths had a survival disadvantage in industrial Dorset" is wrong statement.
The higher biodiversity in an ecosystem means that there is a greater variety of genes and species in that ecosystem. A great variety of genes and species means that the ecosystem is better able to carry out natural processes in the face of external stress. Thus, the ecosystem is more sustainable.
