Answer: carbohydrates,lipids , protein and nucleic acids.
Explanation:
Answer:
1. every organism on the food chain will be affected. the ones below it will have a higher population, and the ones above it will have a lower population.
2. biodiversity is the idea, that all life is different, and environments thrive with it.
3. biodiversity is important in an ecosystem because if you take out biodiversity, you essentially take out all the animals in the given ecosystem.
Explanation:
1. when you remove lets say a spider from a food chain, the bugs that it would've eaten will start growing in population from not being eaten by the spiders. the birds that wouldve eaten the spiders, will decrease from the lack of that food source.
2. is self explanatory
3. if you only had one type of bird in one ecosystem, and that was the only animal in that ecosystem, the birds would all die, because they wouldn't have anything to eat, and nothing would eat it, so they might resort to cannibalism, or, as earlier stated, they would die off, from lack of food. the ecosystem would not be sustainable.
The DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones
Answer:
The correct answer would be - 1/2 ft.
Explanation:
if the scale is 1:4,000
It shows that the model plane will fly 1ft above the ground., the original plane flyes 4,000ft above the ground,
Now, if the plane flies 2,000ft above the ground, this is half times as the scale given, then the model plane will also fly half times as the number from the scale.
1/2*1ft = 1/2ft.
Now, we also can do it as:
4000 ft equivalent to 1 ft.
2000ft equivalent to x
x = 1ft*(2000ft/4000ft) = 1ft*1/2 = 1/2ft.
