Compare and contrast the esophagus with the small intestine pls. How are they similar?

Biology

r-ruslan [8.4K]3 years ago
3 0

Answer:

that connects to the small intestine. This region includes the pyloric sphincter, which is a thick ring of muscle that acts as a valve to control the emptying of stomach contents (chyme) into the duodenum (first part of the small intestine).

schepotkina [342]
Gross motor skills involve large muscles in the arms legs and torso. The general guidelines for gross motor development for children 4 years of age include running, jumping and climbing well and control their direction. They can hop on one foot and they start to skip at this age. At this stage, they are also able to ride a tricycle and reliably catch a ball.

How do the hormones of the pancreas maintain homeostasis?
faust18 [17]
Hormones glucagon and insulin are produced in the alpha and beta cells respectively in the Islet of Langerhan in the pancreas. They are involved in the negative feedback system of blood glucose regulation in homeostasis.

GLUCAGON: when there is a low blood glucose concentration, the pancreas detect this and alpha cells produce and release glucagon. Glucagon causes the cells of the body to absorb less glucose from the blood. It also inhibits the process of converting glucose into glycogen (glycogenesis) and cause gluconeogenesis (process of converting amino acids/proteins and lipids/fats into glucose) and glycogenolysis (conversion of glycogen to glucose). Finally, glucagon decreases the rate of respiration so less glucose is required.

INSULIN: when blood glucose is high, insulin is released. Insulin binds with cell surface receptors of cells and activates the enzymes attached to the receptor. The enzymes cause a conformational change in the structural proteins that surround glucose transport protein containing vesicles, causing them to move out of the way so the vesicles migrate up to the cell membrane and glucose transport proteins can fuse with it. Thus, more glucose can be taken in by cells. Insulin also cause glycogenesis (converting glucose into glycogen) and inhibits gluconeogenesis and glycogenolysis.

Basically insulin decreases blood glucose concentration (eg. after eating) and glucagon increases it (eg. skipping breakfast in the morning)

the eyeless gene is required for eye formation in drosophila. it encodes a homeodomain. a. what would you predict about the bioc
Arte-miy333 [17]
<h3>Briefing:</h3>

In Drosophila, the eyeless gene is necessary for the development of eyes. Given that it encodes for a homeodomain, its protein may have a role as a transcription factor that binds DNA in a specific sequence. In situ hybridization can be used to study the gene's mRNA expression pattern, and immunological methods can be used to study the protein.

A. Since the eyeless gene in Drosophila encodes for a homeodomain, one potential use for its protein is as a DNA-binding transcription factor that binds to specific DNA sequences.

B. As implied by its function, the eyeless gene should be expressed in the Drosophila cells in charge of eye formation. In situ hybridization of the gene's mRNA expression is one potential test to find the gene. The protein can also be seen via a variety of immunological and staining methods. It is possible to do gene deletion experiments to see if Drosophila will retain its eyes or go blind. Additionally, genetic engineering can determine whether the eyeless gene expressed in other organs can result in the creation of eyes.

C. Transgenic tests can be used to determine whether the Small eye and Aniridia genes function similarly to the fly eyeless gene. Since both of these function as master switches for the genes that create eyes, it is possible to transfer the mouse Small eye gene into Drosophila to observe whether it is expressed. These, however, are simply Drosophila eyes and not comparable to mouse eyes.

<h3>Describe DNA:</h3>

All known organisms, including many viruses, require deoxyribonucleic acid, a polymer comprised of two polynucleotide chains that coil around one another to create a double helix, to develop, function, grow, and reproduce. DNA and ribonucleic acid are examples of nucleic acids.
