Answer:
Carotenoids and Anthocyanins
Explanation:
During the winter the sunlight is limited for a long period of time. Plants will lose their leaves but first they will turn bright colors. The reason for this is as follows:
Plants' leaves appear green because of the presence of chlorophyll. During the fall the plants attempt to save energy. So, before they drop the leaves they first break down the chlorophyll into smaller molecules so they do not have to make the molecules from scratch all over again when spring comes. What is left behind is the Carotenoids that appear yellow and orange and Anthocyanins that appear purple.
Organisms whose cells do not contain a well-defined nucleus are placed in the kingdom Fungi is false.
False.
<u>Explanation:</u>
Fungi are eukaryotes that contain many membrane-bound organelles and a nucleus. The Fungi kingdom consists of many living organisms though fungi are more plant-like organisms but are closely related to animals.
Fungi are generally heterotrophic because they use the organic compound for a source of energy.
Many fungi produce haploid cells that undergo mitosis to become multicellular. They play an important role in the ecosystem because they break down organic plus inorganic materials into molecules.
Answer:
Option-A
Explanation:
In the given question, the person predicts that if CO₂ level in the atmosphere will be increased then the phytoplanktons will grow more and the atmospheric carbon will be absorbed and will be fixed.
This statement juts seem like assumptions and if we consider this as a hypothesis then the facts will not be in favour of this hypothesis.
In the present day, the CO₂ level has already increased but the plants are not been able to utilise the Carbon dioxide and reduce global warming as the carbon uses free carbon from the atmosphere only and not bound carbon.
Thus, Option-A is correct.
a glacier made of ice can erode a landscape made of rock because there can be water held within the rock that gets frozen, and because water expands when it is frozen the rock breaks apart and the glacier grinds its' way 'downhill' (down a mountain range, a good example of this is the Appalachian mountain range) and carves out a significant amount of material that is below it, as well as the materials frozen inside of the glacier. so glaciers can freeze the rocks, and then scrape away any material that is softer than rock.
reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population.
