Answer:
Xylem transports only minerals and waters from the roots. Phloem transports food materials that are prepared by the green parts of the plants to other parts of the plant. ... Xylem is the dead tissues at maturity, but no cell contents. Phloem is the living tissue, but not with the nucleus.
Answer:
There is a 50% chance of getting Huntingdon's disease.
Explanation:
Assume the affected parent is Hh, where H is the Huntingdon's disease allele and h is the unaffected allele. One parent is unaffected, or hh. You have a 50% chance of getting the H allele from the affected parent.
If I had the choice to get tested, for Huntingdon's disease, I would do it. I would want to know so that I wouldn't live my life worrying about it everyday.

Answer:
The correct option is B) adaptation
Explanation:
The features and properties of an organism that make it favourable to live in an environment are termed as the adaptations of that organism. Over time, evolution occurs and organisms with better adaptations survive as they are better suited to live in a particular environment. The light-coloured moths were adapted to live on Earth when the colour of the trees had not gone dark. With time, as the colour of trees got darker, the moth had to change colour to be better adapted to live on Earth.
Answer:
The structure and function of the chromosome are different in both the prokaryotic chromosome and eukaryotic chromosome. They differ in their size as the genetic information they carry is different from one another.
Eukaryotic chromosome have a different shape from the prokaryotic chromosome as the bacterial chromosome is circular and less complex due to no histone found in prokaryotes as we see in the eukaryotic chromosome. SIze of the bacterial or prokaryotic chromosome is also small and not found in condensed form as these cells carry less genetic information than eukaryotic cells.
