Describe the structure and the function of the stomach. Be sure to include cells and tissues relating to this organ.
Connective tissues support the tissues of the mucosa and connect it to the muscularis layer.
The blood supply of the submucosa provides nutrients to the wall of the stomach. Nervous tissue in the submucosa monitors the contents of the stomach and controls smooth muscle contraction and secretion of digestive substances.
What is the function of the stomach?The stomach secretes acid and enzymes that digest food. Ridges of muscle tissue called rugae line the stomach.
The stomach muscles contract periodically, churning food to enhance digestion. The pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
Thus, this could be the answer.

b. xylem
What are Vascular tissues?Vascular tissues in plants are specialised tissues which transport nutrients and water through the plant. They are made up of two distinct kinds of tissues: xylem and phloem.
Xylem is in charge of carrying water and minerals that are dissolved from the plant's roots to its leaves. It is made up of many cell types, such as tracheids, vessel components, and fibres. Tracheids and vessel elements are long, hollow structures that create lengthy tubes when stacked end to end.
Sugars and other organic compounds are transported from the leaves to the remainder of the plant by phloem. There are two sorts of cells in it: sieve tube elements and cell companions. Sieve tube components are long, narrow cells that run end to end.
Therefore, the vascular tissues identify as:
a. phloem

Explanation:
Here's a quote: "The colon secretes mucus to bind and lubricate the food waste to help it pass through smoothly as it is dehydrated." -the Cleveland Clinic
A student carried out an experiment to model the digestion of starch by the enzyme amylase in the small intestine.
Visking tubing is a selectively permeable membrane that has small holes in it to allow small molecules to pass through. At regular intervals, the student tested the liquid inside and outside the Visking tube.
How could the student test for the presence of starch inside the Visking tubing?
Answer:
Put one drop on the dimple tile, and the rest in a test tube. Then put the teat pipette back in the water outside the Visking tubing. Test the drops of liquid in the dimple tile by adding one drop of iodine solution from the dropper bottle. If they turn blue-black, the liquid contains starch.

Which action has a positive effect on air resources?
using fossil fuels
building new homes
walking to work or school
removing vegetation such as trees
Answer:
Person above me or below me is correct :)
Explanation:
The answer is C !!
- Have a good summer :)
Utilising fossil fuels has a detrimental impact on air quality because they produce dangerous pollutants like carbon dioxide and nitrogen oxides when they are burned.
What are the contaminants linking to the air pollution ?These contaminants are linked to higher air pollution levels, which can lead to a variety of health problems, such as heart disease and respiratory disorders. The effects of new house construction on air resources are complex.
On the one hand, since burning fossil fuels for energy and releasing building materials can result in the emission of hazardous chemicals, construction may increase air pollution. On the other side, if new homes are constructed in places with fewer air pollution, as in rural regions, they may result in better air quality.
A benefit of walking to work or school an advantage for air resources. Walking does not emit any pollutants into the air, making it a zero-emission mode of transportation.
Additionally, walking lessens traffic on the roadways, which can lessen vehicle-related air pollution. Air resources may suffer if trees or other vegetation are removed. By providing shade, trees not only assist to filter airborne pollutants, but they also help to chill the air. Because air pollutants are not being filtered out as well when trees are cut down, this might result in higher air pollution levels.

The process in which mRNA copies of a gene are made and then transported to ribosomes and translated
into polypeptide chains is called _____
a. translation
b. protein synthesis
c. genetic sequencing
d. transcription
The central dogma is the process of the formation of the protein from DNA. The polypeptide chains formed from mRNA are produced through translation. Thus, option a is correct.
What is translation?The translation is the central dogma process that translates the transcripted mRNA copy into amino acids that interlink with peptide bonds to produce polypeptide chains. Translation occurs outside the nucleus.
The duplicated DNA undergoes transcription to produce an mRNA copy that gets transported to the ribosome that translates the mRNA with the help of the tRNA and rRNA to yield chains of amino acids that produce proteins.
Therefore, the mRNA is transported to the ribosome and gets translated to proteins through the process of translation.

Rabbits were introduced to Australia by humans and have caused severe disruptions to the natural ecosystem. How would you classify these rabbits?
The rabbits would be classified as exotic invasive species.

Invasive attributes include the ability to spread or multiply at a fast rate, sometimes secreting biological chemicals to inhibit the growth of other species.
Exotic invasive species are invasive species that are introduced, rather than being native to the ecosystem.
