Answer:

Fungi most fungi produce cellulases.

Explanation:

Fungi are eukaryotic microorganisms, however unlike other eukaryotes. Their cell wall is made up of chitin instead of cellulose.

Chitin is a fibrous polysaccharide found in the exoskeleton of arthropods and the cell wall of fungi.  where as cellulose is also a polysaccharide which is an important structural component of plant cell wall.

Since fungi are saprophytic they produce enzymes such as cellulases that will help in breakdown of cellulose for food.

They cannot have a cell wall made of cellulose.

Which pollution type resulted in the most hypoxic waters? Support this with evidence from your data.
KengaRu [80]

The pollution types that will result in most hypoxic waters is :

  • Fossil fuel burning and
  • Agricultural runoff

<h3>Hypoxic water </h3>

Hypoxic waters are waters with low concentration of oxygen and this can be caused by the presence of excessive nutrients such as nitrogen. and also can be caused by layering. These are caused by saline gradients.

The excessive nutrients present in hypoxic water support the growth algal and eutrophication.

Hence we can conclude that The pollution types that will result in most hypoxic waters is : Fossil fuel burning and Agricultural runoff

A mutation occurs in an original DNA template that changes the DNA, changes the RNA, but does not change the protein sequence. W
jonny [76]

Answer:

<h2>The changes that do not affect the function of a protein are called silent mutations.</h2>

Explanation:

As given here as a mutation occurs in an original DNA template that changes the DNA, by transcription this mutation passes into RNA and changes the RNA, but it does not change the protein sequence, it means that this mutation could be silent mutation.

Silent mutation is the mutation which cause the change of a base in that, after the mutation the codon codes for the same amino acid, or the amino acid which do no cause any change in the protein, hence these changes do not affect the function of a protein.

When a person drinks alcohol, the rate of urination increases. This suggest that antidiuretic hormone (ADH) may be affected by a
Ulleksa [173]

Answer:

d. alcohol inhibits the release of ADH

Explanation:

Alcohol play an opposite role in water reabsorption. ADH is made in supraoptic nuclues of hypothalamus and transfers fby neuron to posterior pituatry where it gets stored and secreted. Alcohol stops the release of ADH from posterior pituatry which decreases the serum level of ADH. As the ADH level lowers it wont be able to reabsorb water from the distal/collecting tubules of kidneys leading to increase in urine volume and urination.
