Prostaglandins are a class of lipid produced from fatty acids that affect arterial smooth muscle cells to change blood pressure.
What function do prostaglandins serve in inflammation?Lipid acetateoids called prostaglandins are produced from arachidonic acid.They both support homeostatic processes and control pathogenic processes, such as the inflammatory reaction.Inflammation, which is accompanied by the signs of redness, swelling, pain, and fever, is brought on by the high amounts of prostaglandins that are created in response to injury or infection. This plays a crucial role in the body's typical healing process.What cause prostaglandins?Prostaglandins cause the muscles in your uterus to contract during your menstruation. These contractions aid in the uterine lining's removal.Prostaglandin levels can make period cramps worse, and hard contractions can narrow the blood arteries surrounding the uterus.

Smoke arising from the ash of the cigarette or cigar is called blank______, which is higher in many carcinogens than is the firsthand smoke delivered to a smoker's lungs.
Sidestream smoke, which is the smoke that emanates from the ash of the cigarette or cigar, contains more carcinogens than directly smoke does when it enters a smoker's lungs.
What effects do carcinogens have on the body?Chemical compounds, viruses, or even cancer-treating drugs or radiation treatments can all be carcinogens. Different ways exist for carcinogenic compounds to cause cancer. Some carcinogens can cause cancer even when they do not directly cause it. Cancer can also be brought on by prolonged, high-level exposure to carcinogens.Can the lungs of smokers recover?Smoking damages your airways and the tiny air sacs (alveoli) in your lungs, which can lead to lung disease. Along with COPD, smoking causes two lung diseases: emphysema and chronic bronchitis.Smoking cigarettes is the primary cause of lung cancer in most cases.When you stop smoking, your lungs start to repair straight immediately, so stopping sooner rather than later can benefit your general health.learn more about carcinogens here

lesson of the kaibab hypothesis?
Relationships between organisms and their physical surroundings as well as forces inside the biotic community have the potential to change the environment. The maximum number of creatures that a region can sustainably support is known as an ecosystem's carrying capacity. When a population is dense, the habitat may undergo such significant changes that the ecosystem is no longer suited for the survival of that species. For instance, excessive grazing on a piece of land may prevent it from supporting the grazing of the animals inhabited there.
Predators were eliminated and the forest service outlawed hunting.According to the graph, by 1924, the population had gotten out of hand; 100,000 people were living on a plateau with a carrying capacity of 30,000.Because the deer destroyed their habitat, there were 100,000 deer where there should have only been 30,000, which caused the population to fall.Due to natural predators and legal hunting, the deer population was much below its carrying capacity.The deer were unable to survive on the range after hunting was once more permitted.

The tails of the core histone proteins can be chemically modified by the covalent addition of what type of chemical group?.
Answer:
The tails of the core of proteins can be chemically modified by the covalent addition of acetyl, methyl and phosphate.
Histone and DNA have complex interface. Every nucleosome has 142 hydrogen bonds have seen between histone core as well as the DNA. An amino acid backbone of both the histones as well as the phosphodiester backbone of the whole DNA is where about half of these linkages are formed. Condensation of chromatin could be facilitated by methylating the histone tails inside the chromatin. DNA can be accessed for transcription by acetylation of histone tails within chromatin. Certain types of chromatin change could be transmitted to the next cell generations. The DNA is coiled more securely all around histone cores when the histone tails are deacetylated, which makes it more difficult for transcriptional to attach to the DNA. This process, termed as gene silencing, results in lower levels of gene expression.

The na glucose symporter is an example of active transport, and it is found only on epithelial cells.
A transmembrane protein known as na glucose symporter is a sort of sodium-driven secondary active transport that occurs in the epithelial cells of the small intestine. The sodium-glucose symporter is found in the apical membrane of epithelial cells. The symporter binds to sodium and glucose, which are subsequently co-transported into the epithelial cells simultaneously. The sodium-driven glucose symporter utilizes the potential free energy stored in the sodium electrochemical gradient (low sodium concentration inside epithelial cells) generated by the Sodium-Keto pump.

Which neurotransmitter stimulates skeletal muscle cells to contract but slows contractions of the heart?.
The neurotransmitter that stimulates skeletal muscle cells to contract but slows contractions of the heart is acetylcholine.
Neurotransmitters are chemical messengers that are produced inside the neuron and play a role in the nervous system to transmit messages from nerve cells to the targetted cells.
Acetylcholine is synthesized from acetyl-CoA and choline by the cholinergic neurons. Acetylcholine stimulates muscle cell contraction by binding to its receptors on muscle fibers which results in the opening of the sodium channels so that sodium ions can enter the cell which eventually results in contraction.
The muscarinic M2 receptors present in the heart slow down the heart rate by decreasing the rate of depolarization. Acetylcholine binds to these receptors and activates them which results in decreased contractions of the heart.

True. People with difficulty seeing objects at a distance are said to have myopia.
What is myopia?Nearsightedness (myopia) is a common vision issue in which you can see items close to you well but objects farther away are indistinct. It happens when the shape of your eye causes light rays to bend (refract) wrongly, focusing images in front of your retina rather than on your retina.
Symptoms of nearsightedness may include:
Blurry vision when looking at faraway objectsThe necessity to squint or partially close one's eyelids in order to see clearlyEye strain causes headachesDifficulty seeing while driving, especially at night (night myopia)A refractive error is what leads to nearsightedness.

In the field of science, a regulator protein can be described as a kind of protein that affects the transcription of a gene by having an influence on particular DNA sites. The rate of synthesis of various proteins is controlled by the regulator proteins.
A repressor is a kind of regulator protein that prevents the transcription of a particular gene. When the rate of a protein in the body has reached normal, the transcription of the protein needs to be stopped in order for more protein of that kind to be formed.

b. In the school pond there were lots of water lilies with large leaves covering the surface. There were not many plants growing below the surface. Suggest a reason for this.
Answer:
because the water lillieswere covering the pond so less light was entering
Answer:
The reason for this because no plant grows in no light area.
Explanation:
In the second answer, we can see that the pond is covered with water lilies which have larger leaves covering the large surface area of water, not allowing sunlight to pass through it. Sunlight is necessary to carryout photosynthesis, which means plant don't grow in no light condition. Hence, no plant grows in no light area.
