Eukaryotes are organisms whose cells have a nucleus enclosed within a nuclear envelope.
Earth's mantle plays an important role in the evolution of the crust and provides the thermal and mechanical driving forces for plate tectonics. Heat liberated by the core is transferred into the mantle where most of it (> 90%) is convected through the mantle to the base of the lithosphere.
Answer:
The correct answer is - B. Lichens.
Explanation:
Lichens are one of the pioneer species that can grow on bare rock such as moraine and help make soil for further ecological succession and making ground for other species.
Breaking the bare rocks to convert into the soil is part of the primary succession. Lichens are colonized over these rocks and they contain acid which leads to the breakdown of the moraine and other rocks.
Answer:
2, only the moose with the largest feet
Explanation:
If the moose species developed larger feet, then the cause of it has to be for their survival. So the ecosystem they lived in had to make it so the larger feet were helpful. That crosses out 1 and 3. The problem said nothing about the moose having smaller feet so, the answer has to be 2.
I hope this helps :)
Answer:
The phrase "eating like a bird” is inaccurate because the eating habits of birds and the amount of food they consume are a function of their size, activity and metabolism, amount of food that would be insufficient for one person.
Explanation:
The phrase "eating like a bird" establishes a comparison between the feeding of a bird and that of a person, referring to the small amount of food that birds consume.
In fact, birds consume food according to the high energy demand of flying, its weight, size, activity and metabolism. A real comparison would establish that birds even eat more than people.
The feeding of each species is different, and the phrase is inaccurate because it only states that a person who eats little food (less than their requirements) is consuming what would really be enough for a bird.
