what is digestion? Starting from mouth, state the various steps involved in digestion

Answers

Mouth. Food starts to move through your GI tract when you eat. When you swallow, your tongue pushes the food into your throat. A small flap of tissue, called the epiglottis, folds over your windpipe to prevent choking and the food passes into your esophagus.

Esophagus. Once you begin swallowing, the process becomes automatic. Your brain signals the muscles of the esophagus and peristalsis begins.

Lower esophageal sphincter. When food reaches the end of your esophagus, a ringlike muscle—called the lower esophageal sphincter —relaxes and lets food pass into your stomach. This sphincter usually stays closed to keep what’s in your stomach from flowing back into your esophagus.

Stomach. After food enters your stomach, the stomach muscles mix the food and liquid with digestive juices. The stomach slowly empties its contents, called chyme, into your small intestine.

Small intestine. The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine, and push the mixture forward for further digestion. The walls of the small intestine absorb water and the digested nutrients into your bloodstream. As peristalsis continues, the waste products of the digestive process move into the large intestine.

Large intestine. Waste products from the digestive process include undigested parts of food, fluid, and older cells from the lining of your GI tract. The large intestine absorbs water and changes the waste from liquid into stool. Peristalsis helps move the stool into your rectum.

Rectum. The lower end of your large intestine, the rectum, stores stool until it pushes stool out of your anus during a bowel movement

Answer:

The gastrointestinal system starts in the mouth. In reality, as soon as you eat the first bite, digestion begins here. Chewing splits the meal into sections that are easier to eat, and saliva combines with food to start breaking down the body into a shape that you can consume and use.

Explanation:

The mechanism of digestion can be divided into various phases, such as mouth, stomach, small and large intestine.

A complicated mixture of mechanical and chemical processes are used in digestion. The mechanism includes food intake and push, mechanical or physical digestion, chemical digestion, absorption, and defeat.

A sequence of bases on DNA that code for a specific protein

4) A sequence of bases on DNA that code for a specific protein.

Gene:A gene is the basic physical and functional unit of heredity.Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. Alleles are forms of the same gene with small differences in their sequence of DNA bases.Every person has two copies of each gene, one inherited from each parent.

Thus, option 4 is correct.

how lond does it take harry to go 0.7 miles if he can run 12 miles in 6 minutes

Answers

Answer:

Harry will take 21 seconds.

Explanation:

Speed of Harry = [tex]\frac{\text{Distance covered}}{\text{Time taken}}[/tex]

Since, Harry covers 12 miles in 6 minutes,

Then the speed of Harry = [tex]\frac{12}{6}[/tex]

                                          = 2 miles per minute

If he covers 0.7 miles then time taken by him will be,

Time taken = [tex]\frac{\text{Distance covered}}{\text{Speed}}[/tex]

                   = [tex]\frac{0.7}{2}[/tex]

                   = 0.35 minutes

                   ≈ 0.35 × 60 seconds

                   = 21 seconds

A farmer grows several crops on a farm that has mostly shallow, sandy soil, meaning they have
a low water storage capacity and a high infiltration rate. Which of the following irrigation
methods would be the best suited for this farm?
Select one:
O a. Drip irrigation
O b. Surface irrigation
O c. Flood irrigation
O d. Furrow irrigation

Answers

..............C...............

For a sandy soil farmer should use drip irrigation method over surface irrigation.

Sandy soils have a low water storage capacity and a high infiltration rate.  Therefore they need frequent but small irrigation methods, drip irrigation is most suitable method than surface irrigation.

In other irrigation methods such as Surface irrigation, Flood irrigation, Furrow irrigation water is discharged in quite large amounts but the soil lost it due to the high infiltration rate.

Therefore, for a sandy soil farmer should use drip irrigation method over surface irrigation.

What are the DNA base pairs?

Need asap

Answers

Answer:

I hope i helped

Explanation:

A base pair (bp) is a fundamental unit of double-stranded nucleic acids consisting of two nucleobases bound to each other by hydrogen bonds. They form the building blocks of the DNA double helix and contribute to the folded structure of both DNA and RNA. Dictated by specific hydrogen bonding patterns, "Watson–Crick" base pairs (guanine–cytosine and adenine–thymine) allow the DNA helix to maintain a regular helical structure that is subtly dependent on its nucleotide sequence. The complementary nature of this based-paired structure provides a redundant copy of the genetic information encoded within each strand of DNA. The regular structure and data redundancy provided by the DNA double helix make DNA well suited to the storage of genetic information, while base-pairing between DNA and incoming nucleotides provides the mechanism through which DNA polymerase replicates DNA and RNA polymerase transcribes DNA into RNA. Many DNA-binding proteins can recognize specific base-pairing patterns that identify particular regulatory regions of genes.

All frameshift mutations are equal

Answers

Answer:

All frameshift mutations are equal

Explanation:

Frameshift mutation is a type of mutation caused by insertion or deletion of nucleotide base(s) in a genetic sequence causing that sequence to be read in a different way from what was originally planned.

The bases in the sequence of a gene is read in three's (codon), however, when one or more bases is added (insertion) or removed (deleted), the reading frame is altered causing the sequence to be read in a completely different order that can result in a protein that is non-functional.

However, FRAMESHIFT MUTATION is so potent that it affects the sequence no matter where it occurs. In other words, the effect of all frameshift mutations are equal.
