djyliett [7]3 years ago

After sensing a drop in calcium levels in the body,parathyroid hormone from the parathyroid glands will be secreted in a negative feedback mechanism of homeostasis
first the parathyroid hormone stimulates release of calcium ions from the bone through the process of bone reorption
then the parathyroid hormone will reduce urinary excretion of calcium by increasing its re absorption in the nephron
finally , the parathyroid hormone will increase the rate of vitamin d synthesis in the small intestine to yield more calcium

Which two codons in the mRNA represent the amino acid phenylalanine
Trava [24]

Answer:

UUU and UUC

Explanation:

Information that encodes certain functional products called PROTEIN are present in the DNA molecule. However, the information needs to be expressed via the processes of transcription and translation. Transcription is the synthesis of a mRNA using a DNA template.

The mRNA then undergoes translation, where it is read in a group of three nucleotides called CODON. Each CODON specifies a particular amino acid. Due to the degenerate nature of the genetic code, more than one codon can specify one amino acid.

Hence, in the case of phenylalanine amino acid, codons UUU and UUC both specify it. This means that whenever UUU and UUC are read during translation, a phenylalanine is added to the peptide chain.

Some peeled pieces of apple were placed in distilled water and some in very salty water. The cells in the apple pieces will
QveST [7]
I think that they will g<span>ain water in the distilled water and lose water in salty water. I think water will be lost because salt is used as an drying agent, it is why when it snow they will put salt on ice to keep the ice from being slippery because it dries things up. Distill just means to purify something.</span>

What is a complex sugar
storchak [24]

Answer:

Complex Carbohydrates: Also know as polysaccharides (poly = many), these carbohydrates have more than two units of glucose (sugar) linked together. Polysaccharides are generally not sweet and are not water soluble. Starches and dietary fiber are complex carbohydrates.

Complex carbs pack in more nutrients than simple carbs. They're higher in fiber and digest more slowly. This also makes them more filling, which means they're a good option for weight control. They're also ideal for people with type 2 diabetes because they help manage blood sugar spikes after meals.

Simple carbs — also known as simple sugars — contain one or two sugar molecules, whereas complex carbs have three or more. A simple sugar may be a mono- or disaccharide.
