Answer:
<h3>Molisch’s test is a chemical test which is used to check for the presence of carbohydrates in a given analyte. This test is named after Czech-Austrian botanist Hans Molisch, who is credited with its discovery. Molisch’s test involves the addition of Molisch’s reagent (a solution of ∝-naphthol in ethanol) to the analyte and the subsequent addition of a few drops of concentrated H2SO4 (sulphuric acid) to the mixture.</h3>

Answer:
No it would not be useful for cell.
Explanation:
RNA polymerase uses only one strand of DNA which is called the template strand for the synthesis of mRNA. The other strand which is not used to make mRNA is called the coding strand.
If an RNA polymerase is designed which transcribe both the strand than two different strands of mRNA will be generated that will have different nucleotide sequences and will code for different proteins. So one strands will generate a protein which have different amino acids sequence that will complicate the overall process for the cell.
Another problem is if two RNA strands are formed then they can form a double helix and the ribosome might not be able to bind on them and translation might stop. Therefore it would not be useful for cell.
Answer:
They will have a large amount of genetic variation.
Explanation:
Scrapping pollens obtained from one plant to the flower of another plant (different variety but same species) would lead to increase in the genetic pool. The new hybrid plant would carry genetic features from both plants varieties. This process is also used to develop new varieties and have been recognized as cross-pollination. This process is generally preferred over genetic modification (GM) because of more nature friendly.
Answer:
C) they lack lignified vascular tissue. (
Since they do not have vascular tissues, they are not able to develop vertically like the trees we know.)
Explanation:
A)
Plants do not have "sperm". They have sporophytes or gametophytes.
B) No specific parasitic bacteria of bryophytes are known.
D) In fact, they have. Although they require water for their reproduction, some species of bryophytes are found in deserts.
E) Rhizoids are not weak, otherwise they would not have the ability to keep bryophytes attached (mosses).
