The three evidence that support the existence of plants on Antarctica are:
- Climate;
- Pollen;
- Herbivorous animals;
Apart from the plant fossils found on Antarctica, there are few other evidence that suggest that plants existed in the past on the now frozen continent. Some of those evidence for the existence of plants on Antarctica are the pollen found in the rocks and fossils of organisms, the climate records, as well as the herbivorous animals.
The pollen is only released by the plants, thus that is a sure indicator that plants were occupying this part of the world.
The climate records on Antarctica that can be seen in the rock layers, suggest that for most of its existence, Antarctica had a warm and wet climate, which is perfect conditions for the plants to thrive.
The herbivorous animals are feeding themselves on plant material, so since there's fossils of herbivores in Antarctica, it for sure is an evidence that there were plants existing in order for them to feed and be able to live in there.
Answer:
As air pressure decreases oxygen continues to account for about 21% of the gasses in the air as it does at sea level. But, there is less oxygen because there is less of all of the air's gasses
Answer:the part of the brain that has most likely been damaged in this experiment is the suprachiasmatic nucleus (SCN) found in the hypothalamus of the brain.
Explanation:
circadian rhythms are behavioural changes that respond to light and darkness in an organisms environment. The sleep-inducing wake cycle is a good example of a circadian rhythm. In the experiment, the disruption of the mouse SCN led to development of imbalances in the circadian rhythm of sleep and wake cycle leading to falling asleep and waking up at random times of the day and night. I hope this helps. Thanks

Explanation:
DNA is a double helix molecule composed of two complementary DNA strands which are in turn composed of four different nucleotide bases: Adenine (A), Guanine (G), Cytosine (C) and Thymine (T). In the DNA molecule, G and C are bound together as a base pair, while A and T are bound together as another base pair. This complementary base pairing structure means that both DNA strands are complementary to each other. In this case, since the sequence of one strand is "TCGAACTCA", the complementary DNA strand would have the sequence "AGCTTGAGT".
The outcome of the gram stain is based on differences in the cell's cell wall(different composition of the cell wall
