Answer:
None of these.
Explanation: The plants like cycads and ginkgos have swimming sperms. they need water to complete their life cycle.
There are many adaptations seen in the plants like liveworts, ferns and mosses in which they require water to complete its life cycle. This adaptation is not only restricted upto cyptograms. This can also be seen in the plants like ginkgos and cycads. Their sperms are very strange.
Answer:
The chemical reaction that represents the process of aerobic cell respiration is oxygen + glucose → water + carbon dioxide + energy
Explanation:
Cell respiration occurs in the mitochondria of eukaryotic cells and consists of a series of chemical reactions in which energy in the form of ATP molecules is obtained from a glucose molecule in the presence of oxygen.
<u>Glucose is the main energetic substrate</u> to be able to synthesize energy in the form of ATP, through oxidative phosphorylation. At the end of the process ATP is obtained as products, and as waste compounds water and carbon dioxide, which can be schematized in the following chemical reaction:
<em> C₆H₁₂O₆ + 6O₂ → 6H₂O + 6CO₂ + ATP ↑</em>
<em> Glucose + Oxygen → Water + Carbon dioxide + Energy ↑</em>
This reaction summarizes what happens in aerobic cellular breathing, which is necessary to synthesize energy for cellular functions.
The other reactions:
- <em>oxygen + water </em><em>→</em><em> glucose + lactose
</em>
- <em>glucose + lactose </em><em>→</em><em> oxygen + water
</em>
- <em>water + carbon dioxide + energy </em><em>→</em><em> oxygen + glucose</em>
<em>do not represent the components or the order of the reactions that occur in aerobic cell respiration</em>
A great amount of Antarctic animals feed on them. Whales, penguins, fish, birds, etc. They eat phytoplankton.
