Orchids are a recently evolved plant that have a novel feature known as aerial roots. What is the most likely function of an orc

hid's specialized roots? Aerial roots preserve water in the orchid. Aerial roots allow the orchid to attach itself to trees. Aerial roots produce food for the orchid through photosynthesis. Aerial roots anchor the orchid to the ground.

<u>Answer</u>: Aerial roots allow the orchid to attach itself to trees.

<u>Explanation</u>:

  • The roots of the plant that grow above the ground are known as aerial roots.
  • These aerial roots are found in orchids to attach to the tree.
  • The plant may or may not retain its terrestrial root.
  • Examples of the orchids with aerial roots are climbing orchids and epiphytic orchids.
  • These roots help the plant to firmly stay on the branches of the trees and compete with others for sunlight .

Elden [556K]
The correct answer for the question that is being presented above is this one: "Synthesized." A scientist isolates a gene from a human cell that codes for a specific protein. The gene is inserted into a bacterial plasmid in order to mass produce the protein for medical purposes. The next step in mass production of the protein would be synthesized of the bacterium containing the modified plasmid.<span>

In humans, methylation of chromosomal DNA is a signal that often leads to
Ulleksa [173]

Answer:

The correct answer will be option-formation of heterochromatin

Explanation:

Methylation of DNA is the epigenetic mechanism which controls the expression of a gene by adding a methyl group to the cytosine bases in eukaryotic DNA.

The methylation of DNA converts the cytosine residues to the  5-methylcytosine catalysed by DNA methyltransferase enzyme. This results in the silencing of the gene and transcription get switched off.

Studies have shown that DNA methylation is involved in the formation and maintenance of the heterochromatin structure which is the condensed form of the chromatin in which transcription is switched off.

Thus, the formation of heterochromatin is the correct answer.

8. Two rabbits are bred together. One is heterozygous for agouti coat
dusya [7]

Answer:

- Parental cross = Cch  x chch  

- F1 = 1/2 Cch (agouti coat); 1/2 chch (albino coat) >> 1:1 phenotypic ratio

Punnett  square:  

          ch         ch

C       Cch       Cch

ch    chch      chch

 

Explanation:

A heterozygous individual is an individual who has two different gene variants (i.e., alleles) at a particular <em>locus</em>. In this case, individuals having the "agouti coat" trait are heterozygous carrying both 'C' and 'ch' alleles. On the other hand, a homo-zygous individual has the same allele at a given <em>locus</em> (here, the 'chch' genotype associated with the albino phenotype). Therefore, as observed in the Punnett Square above, when a heterozygous parent is crossed with a homo-zygous recessive parent for a single gene, alleles segregate in the gametes of both parents so an expected 1:1 phenotypic ratio will be observed.
