Answer:

A mutation that causes a single letter change in the DNA sequence can affect your protein structure and function because the sequence of letters in a gene determines the sequence of amino acids in the protein that it encodes. A single letter change in the DNA alters the mRNA which alters the amino acid sequence of the resulting protein and sometimes that can cause serious results if it changes the way a protein works.

ex. sickle cell disease - a single letter swap in the gene that encodes the hemoglobin molecule results in deformed red blood cells

Hope that helps.

Cortisol hormones are stress hormones that increase blood glucose levels. When the level of happiness increases the level of cortisol does not increase.

<h3>What are cortisol and its function?</h3>

Cortisol is the steroidal hormone that is produced in the cortex of the adrenal glands and is discharged in the blood vessels when in stress or danger.

It has a variety of functions including regulation of the blood pressure, response to the stressful condition and increase of the metabolism of the body.

It also acts as happiness hormones along with adrenaline and oxytocin but is a major flight or fight hormone and increases the heart rate in dangerous conditions.

Therefore, the statement is false.

Elza [17]

The journey of the food through the digestive system will actually digest the food. The rest will be given out as feces.

<h3><u>Explanation:</u></h3>

The digestive system actually consists of digestive tract and Digestive glands. The processes that are associated with digestive system is - ingestion, digestion, absorption, assimilation and egestion.

The food that is taken is first smashed and chewed into a rough bolus by mixing with saliva. The salivary amylase slightly digests the starch into dextrin.

Then the food is engulfed through the oesophagus into stomach. Inside stomach, the food is mixed with an enzyme pepsin and HCl. Pepsin digests the proteins into peptones and peptides. The food is converted into a bolus and transported into duodenum.

In duodenum, there are several enzymes from small intestine and pancreas breaks the fats into fatty acids, proteins into peptides and starch into carbohydrates like glucose. They are absorbed and the undigested substances are left over ad feces.
