What is hypertension AND how is it prevented?

Answers

Answer:

Hypertension is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. Blood pressure is determined both by the amount of blood your heart pumps and the amount of resistance to blood flow in your arteries. The more blood your heart pumps and the narrower your arteries, the higher your blood pressure.For most adults, there's no identifiable cause of high blood pressure. This type of high blood pressure, called primary (essential) hypertension, tends to develop gradually over many years. Some people have high blood pressure caused by an underlying condition. This type of high blood pressure, called secondary hypertension, tends to appear suddenly and cause higher blood pressure than does primary hypertension. Various conditions and medications can lead to secondary hypertension, including:

   Obstructive sleep apnea

   Kidney disease

   Adrenal gland tumors

   Thyroid problems

   Certain defects you're born with (congenital) in blood vessels

   Certain medications, such as birth control pills, cold remedies, decongestants, over-the-counter pain relievers and some prescription drugs

   Illegal drugs, such as cocaine and amphetamines

Answer:

Hypertension is when blood pressure is too high. It can be prevented by doing things such as eating healthier foods, not doing any smoking, being physically active, getting enough sleep, and maintaining a healthy weight.

Answers

According to the research, most of the carbon quickly enters back into the atmosphere in the form of carbon dioxide.

What is the carbon cycle?

It is the process that describes the flow of carbon (in the form, for example, of carbon dioxide) in the atmosphere, the ocean, the terrestrial biosphere.

Thus, the CO2 in the atmosphere passes through photosynthesis to the plants, also the cycles of respiration and microbial decomposition intervene, which release new CO2 in gaseous form into the atmosphere.

Therefore, we can conclude that according to the research, most of the carbon quickly enters back into the atmosphere in the form of carbon dioxide.

total saturation of protein transporters for a given solute in the renal tubules would result in __________.

Answers

Answer:

absence of that solute from the urine

Explanation:

A protein transporter is involved in the transportation of the ions and the molecules. If a membrane protein transporter gets totally saturated in the renal tubules, then that solute will appear in the urine.

What are transport proteins?

Transport proteins are the transporters that move the molecules, ions, and macromolecules in and out of the cell. They carry the molecules and substances across the biological membrane and allow their diffusion.

If a transport protein saturates a solute totally in the renal tubules, then that solute will get secreted in the urine as they are easily soluble in the water and the fluid of the excretion system.

Therefore, the solute will get excreted in the urine.

A) Top carnivores obtain the maximum energy from the ecosystem.
B) Herbivores have more energy available to them than carnivores.
C) There should be fewer tertiary consumers than secondary consumers.
D) Soil organisms recycle nutrients but not energy back into the ecosystem.
E) Of the energy that is available to the producer level, only ten percent is available to the tertiary consumers.

Answers

In a typical energy pyramid, herbivores have more energy available to them than carnivores, tertiary consumers are fewer than secondary consumers, and soil organisms recycle nutrients.

Energy pyramid in the ecosystem

The producer forms the bases of the energy pyramid of any ecosystem. this is followed by the primary consumers, secondary consumers, tertiary consumers, and quaternary consumers respectively.

The population at each trophic level decreases as we move up, resulting in a form of a pyramid. Also, the amount of energy obtained at each trophic level decreases as we move upward.

Thus, one can effectively conclude that:

Herbivores have more energy available to them than carnivores.There are fewer tertiary consumers than secondary consumers.Soil organisms recycle nutrients but not energy back into the ecosystem.

How and why do water and carbon dioxide function as raw materials during photosynthesis?

Review how sunlight provides the energy to carry out reactions to release oxygen and produce energy-rich carbohydrates.

Answers

Answer:

plants take in carbon dioxide (CO2) and water (H2O) from the air and soil.

Explanation:

During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

(if this isnt what your asking just let me know and i do it again)

Explanation:

photosynthesis is the process in which plant make their own food with the help of sunlight,water and carbon dioxide. water and carbon dioxide are raw materials in photosynthesis because they help to prepare their food.During photosynthesis, plants take in carbon dioxideand water from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

sunlight, water and carbon dioxide helps to produce energy storing carbohydrates.The energy from sunlight drives the reaction of carbon dioxide and water molecules to produce sugar and oxygen, as seen in the chemical equation for photosynthesis.

Explain the DNA Replication diagram above with all the great terms from this chapter. This is a BIG ANSWER.​

Answers

DNA replication or duplication is the process of making copies of DNA by the cell. It involves a series of steps and various enzymes required for the completion of the process.

What is the process of DNA replication?

DNA replication has several steps along with some proteins called replication enzymes as well as RNA.

The process of replication is as follows:

Replication fork: It is made by unzipping DNA into two strands. It is done by break of the purine and pyrimidine bond accomplished by an enzyme called DNA helicase.

Primer binding: After this unzipping, a short piece of RNA which is called as a primer binds to the 3' end of the DNA strand. The primer bound is the starting point for replication. Primers are generated by the enzyme referred to as DNA primase.

Elongation: DNA polymerase aids in the elongation process in DNA replication. As the replication moves in the 5' to 3' direction on the leading strand, the newly formed strand will be continuous. But in the case of the lagging strand replication starts by binding with multiple primers which involve DNA polymerase and then adds pieces of DNA, called Okazaki fragments, to the strand between primers.

Termination: On the formation of both the strands, Exonuclease removes all RNA primers followed by proofreading and then the adhesion of the Okazaki fragments by enzyme DNA ligase.

Thus, these were the steps involved in the process of DNA replication.
