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:
Dissaster like meteorite impacted all type of living forms, however, animals are impacted the most and plants are impacted least. It is possible due to ability of plants to prepare their food on their own as they are autotrophic and use photosynthesis. The raw material for preparing these are easily available that are sunlight, CO2 and water.
They are not depende on other for their cellular respiration. The other major reason is that the Plant seeds can remain dormant in unfavorable conditions for many years in the soil. The roots always provide nutrition even the stems get effected.
Answer:
Because sickled cells restrict blood flow, individuals can periodically experience swelling and extreme pain in any body organ or joint. This can last for hours or weeks. Sometimes permanent damage can occur to organs deprived of oxygen and nutrients
Explanation:
Red blood cells are designed to pick up oxygen in the lungs and transport it throughout the body via the circulatory system. Their donut-like shape and water-balloon-like flexibility allows them to pass through even the tiniest blood vessels.
Sickle cell anemia is a hereditary condition that causes some red blood cells to distort into rigid crescent moon shapes.
Normal red blood cells can flow freely through blood vessels. Sickled cells get stuck in the blood vessels and cause blockages.
Answer:
ten to fifteen, I just took the test.
Explanation:
Answer:
water provides the electron that binds the hydrogen atom (of a water molecule) to the carbon (of carbon dioxide) to give sugar (glucose). Water acts as a reducing agent by providing H+ ions that convert NADP to NADPH
