As the Earth warms, scientists worry that some of the carbon in permafrost could escape to the atmosphere as carbon dioxide or methane. Increasing the amount of these gases in the atmosphere could make Earth's climate & more
Explanation:yw
The third one is the right answer.
Mutations appear randomly and these mutations can either have possitive, negative or neutral impact on the individual's survival. The environment of the individual amongst other factor determine the net effect of the mutation. For example:
A mutation on a shade plant for bigger leaves would have a possitive impact on the plants survival due to the increase of the photosynthetic tissue area. On the other hand the same mutation on a desert plant would have a negative impact on the plant's survival due to the increase of the leaf area which leads to increased water evaporation off the plant.
<span>Lamarck believed that organisms could acquire characteristics during their lifetime, that they could pass down to their offspring, but Darwin did not believe these traits could be passed down. Darwin proved that the species adapted to their environment through natural selection. Meaning only the one that could adapt to the changes would survive. </span>
Answer:
Power is measured at three different levels pertinent to flapping flight. The first level is metabolic power input (P met) to the muscles, directly of interest to a flying, foraging bird, and generally a realm of study for respiratory, thermal and chemical physiologists.P met is the rate the bird expends chemical energy to supply the flight muscles, and it may be measured using double-labeled ...
