The correct answer is mentioned as follows:-

<h3>GYMNOSPERM</h3>
  • The less developed plant which does not bear flowers and has covered less seed is called gymnosperm.

According to the question, the diagram is not mentioned in the question hence we can not able to tell the characteristics of the area marked as X. The plants do not look like palm trees.

Hence, provide it with the diagram for better assessment.

Whats the difference between genotype and phenotype.
Olegator [25]

\huge{\green}\fcolorbox{blue}{cyan}{\bf{\underline{\red{\color{red}Answer}}}}

  • The genotype is a set of genes in the DNA which are responsible for the unique trait or characteristics.
  • Whereas the phenotype is the physical appearance or characteristic of the organism.
  • Thus, we can find the human genetic code with the help of their genotype.
  • Organisms may look the same but still may not have the same genotype.
  • One can determine the genotype by the biological tests.
  • On the other hand, the phenotype is determined by an individual’s genotype and can be expressed as genes or by the visible traits.
  • Such traits are hair color or type, eye color body shape, and height, and many such more.
  • It will depend on the genotype but also influenced by the factors existing in the surrounding.

What information could cancer researchers gain from using DNA microarrays?
Evgen [1.6K]

DNA microarrays allow scientists to determine the genotype of a chunk of our genome and also measure the how the genes in that chunk are expressed. Using this technique has been essential in isolating genes that predispose people to cancers, and therefore allowing physicians to preemptively identify and monitor at-risk individuals. For instance, the genes BRCA1, BRCA2, and PALB2 have all been identified (using DNA microarrays) and linked to breast cancer. Knowing this allows individuals to seek out testing and take appropriate measures to prevent cancer/monitor the possible onset of cancer, which has proven to be life-saving.
