Answer: One advantage is, well, the water. There’s plenty of it and it’s all around. Therefore, most aquatic plants do not need adaptations for absorbing, transporting, and conserving water. They can save energy and matter by not growing extensive root systems, vascular tissues, or thick cuticles on leaves. Support is also less of a problem because of the buoyancy of water. As a result, adaptations such as strong woody stems and deep anchoring roots are not necessary for most aquatic plants.
Answer&Explanation:
Most of water become absorbed and transpired(process by which plant loose water through leaves) or by guttation(loss of water inform of drops especially during night which appears as dew through hydathodes)
PEA stands for Phenylethyl Alcohol Agar medium. It is a selective solid medium that is used to culture Gram Positive bacteria. In this medium, phenylethyl alcohol is an active ingredient that inhibits the growth of Gram Negative bacteria. It causes leakage in the cell membrane of Gram Negative bacteria. It is also used for the growth of obligate anaerobic bacteria.
Answer:
Yes, the protein is found on the surface of the red blood cell which is represented by a positive or negative sign.

Rh factor refers to the class of antigen or protein found on the red blood cell.
If the protein is present, then the person is said to be Rh positive and when the protein is absent the person is said to be Rh negative.
It is imperative to use aseptic techniques whe handling microbial cultures because aseptic techniques:
1. reduce contamination of your cultures from enviornment
2. reduce contamination/transfer of bacteria between different culture smears
3. helps to isolate a single microorganism to get a culture smear of
