Adaptation through natural selection
Answer: Water can hold an unlimited amount of oxygen.
Explanation:
Water cannot hold an unlimited amount of oxygen because it would get to a point where it is saturated as it needs to hold Hydrogen as well. Air on the other hand, has significantly more space for oxygen as it contains only 21% and can keep taking more.
Underwater organisms need oxygen for respiration and a small decrease in the oxygen available in water affects aquatic life because they rely on it to survive.
What’s the answer choices
Answer: Ascomycota
Explanation:fungi are eukaryotic organisms that lacks chlorophyll,roots ,stems and leaves.they feed by decaying death matter and some exist as symbionts.they are found in trees,soil,burnt grass etc.
Fungi may be Unicellular or multicellular and possess whitish and threadlike filaments called hyphae.these hyphae forms a mass called mycellium,which is the main body.
Fungi reproduce asexually through spores.
The Ascomycota is a group of fungi also called sac fungi.their spores are formed in a sac , called ascus.the spores are eight in one haploid spores as they undergo mitotic Division to produce eight nuclei in the same ascus.
Upon maturity,the spores escape through a hole in the ascus and germinate when the fall on favourable places.
