Why rhizoids not called roots?

Biology
1 answer:
garik1379 [7]3 years ago
4 0
Most plants have roots, but there are some
exceptions. The exceptions are bryophytes
and the groups of green algae that are
classified as plants. Bryophytes have rootlike
structures called rhizoids for absorbing
water, but because rhizoids lack vascular
tissue they are not considered roots.

The wild-type form of a gene encodes a protein of length 100 amino acids. A mutant allele has a UAA (instead of the wild-type, C
Orlov [11]

Answer:

48 amino acids

Explanation:

The wild type gene codes for a protein with 100 amino acids. One amino acid is encoded by one triplet code of the gene. This means that the wild type gene has a total 100 triplets or 300 nucleotides to code for a protein of 100 amino acid. Mutation in this protein has introduced the code "UAA" at the 49th codon. The code "UAA" is a stop codon. Therefore, the mRNA transcribed from the mutant allele would code for a protein having 48 amino acids as the protein synthesis will be stopped once the stop codon at the 49th position is read.

Suppose a 0.1M solution of a monosaccharide contains 1000 monosaccharide
seropon [69]

0.1 M solution of a disaccharide solution will contain 2000 monosaccharide molecules.

<h3>What are monosaccharides?</h3>

Monosaccharides, also known as simple sugars are the simplest monomers of carbohydrates which may either be 3 carbon, 4 carbon, 5 carbon, 6 carbon or 7 carbo compounds.

There are two types of monosaccharides;

  • aldoses sugars, e.g. glucose, and
  • ketose sugars e.g. fructose.

When two monosaccharides are linked together by glycosidic bonds to form a single compound, the compound formed is called a disaccharide.

Considering the give question:

Suppose a 0.1M solution of a monosaccharide contains 1000 monosaccharide molecules. How many monosaccharide molecules would be in a 0.1 M solution of a disaccharide.

The number of monosaccharides molecules present in the 0.1 M solution of a disaccharide is determined as follows:

1 disaccharide molecule contains 2 monosaccharide molecules

0.1M solution of a monosaccharide contains 1000 monosaccharide molecules.

0.1 M solution of a disaccharide will contain 2 * 1000 monosaccharide molecules

0.1 M solution of a disaccharide will contain = 2000 monosaccharide molecules.
