djverab [1.8K]

The nutrient is phosphorus

<h3>The phosphorus cycle</h3>

Phosphorus cycles between living components of the earth (biosphere) and the soil (geosphere).

The element's reservoir is mainly the sediments of the ocean and rocks. Phosphorus gets into the soil by weathering of rocks.

Plants are able to pick the element up from the soil and animals are able to get their phosphorus by consuming plants.

When plants and animal die, their body decomposes and the phosphorus in them enters the soil.

Thus, the cycle being referred to in the illustration is the phosphorus cycle.

Answer:

There is no cure for cystic fibrosis, but treatment can ease symptoms and reduce complications.

Explanation:

1). For those with cystic fibrosis who have certain gene mutations, doctors may recommend a newer medication called ivacaftor. This medication may improve lung function and weight, increases the activity of Cystic fibrosis transmembrane conductance regulator (CFTR)protein and reduce the amount of salt in sweat. It has been approved by the Food and Drug Administration for people with cystic fibrosis who are age 6 and older. The dose depends on your weight and age.

2). For people with a certain gene mutation who are age 12 and older, another drug is available that combines ivacaftor with a medication called lumacaftor. This drug is called orkambi.

The use of Orkambi may improve lung function and reduce the risk of exacerbations.

As part of a purification technique, a mixture of small-protein hormones and peptides are placed in a gel and exposed to an elec
lidiya [134]

Answer:

The correct answer is "negative".

Explanation:

At pH 2 the net charge of the R groups of all the amino acids that comprise the peptide in question would be positive. This happens because of the high content of protons in a solution of pH 2, a value that is below the isoelectric point of all the amino acids. Since the peptide would have a positive net charge, it would migrate to the negative terminal of the gel because opposite charges attract each other.
