What is the name of the green stuff in leaves?
Answer:
THE NAME OF THE GREEN STUFF IN LEAVES ARE ChlorophyllA 43-year-old Caucasian man with a 20-year history of bipolar disorder presents for the first time with long-term polyuria and polydipsia. He previously took lithium for mood stabilization for 15 years before initiating divalproex sodium therapy. He stopped using lithium because of the polyuria, but he felt that the polyuria never fully subsided. His weight is stable, and he has no other urinary complaints. His blood pressure is 115/80 mmHg and his physical exam is normal. His urinalysis shows no blood, cells, protein, glucose, nitrate, casts, or crystals.
What is the most likely cause of his polyuria?
1 Central diabetes insipidus
2 Nephrogenic diabetes insipidus
3 Polyuria secondary to hyperglycemia
4 Polyuria following acute kidney injury
5 Polyuria secondary to polydipsia
Answer:
The correct option is 2 Nephrogenic diabetes insipidus.
Explanation:
Nephrogenic diabetes insipidus (NDI) occurs when the renal tubule response to vasopressin (ADH) is weakened, resulting in the excretion of large volumes of dilute urine.
As the renal tubules do not respond to vasopressin (antidiuretic hormone) and are unable to reabsorb filtered water back into the body, the kidneys create a high volume of dilute urine in nephrogenic diabetes insipidus.
Nephrogenic diabetes insipidus (NDI) can be inherited or develop as a result of disorders that impede the ability of the kidneys to concentrate.
Therefore, the correct option is 2 Nephrogenic diabetes insipidus.
That is, the most likely cause of his polyuria is nephrogenic diabetes insipidus.

The pancreas contains exocrine cells that secrete digestive enzymes into the ____________ , and clusters of endocrine cells called pancreatic islets, which secrete insulin and ____________ , to regulate blood glucose levels. When blood glucose levels are high, the pancreas secretes the hormone insulin, which causes the liver to remove excess glucose from the blood and to store it in the liver as ____________ . When this stored form of glucose is low, the liver converts ____________ from fats and amino acids to glucose molecules. Most pancreatic cells produce pancreatic juice, which contains ____________ , to help neutralize the stomach acid. Pancreatic amylase digests ____________ , trypsin digests protein, and lipase digests fat. The major functions of the liver include: removing or detoxifying harmful substances from the blood; storing glycogen, ____________ , and several vitamins; synthesizing many proteins found in the blood ____________ ; and regulating blood cholesterol. Another function of the liver is to produce bile, which is a yellowish-green color because it contains bilirubin, a breakdown product of ____________ . Bile also contains bile salts, which serve to emulsify ____________ in the small intestine.
Answer:
The correct answer is - small intestine; glucagon, glycogen; glycerol, sodium bicarbonate; starch, iron, plasma, hemoglobin; fats.
Explanation:
The digestive enzymes are released in the small intestine by pancreatic cell, the cluster of these pancreatic exocrine cells called pancreatic islets that release insulin and glucagon hormones for controlling blood sugar level.
Insulin stores the excess amount of blood glucose in the liver as glycogen and in the case of low sugar glycerol is converted to glucose from fats. Pancreatic juice contains sodium bicarbonate to regulate acidity and the amylase enzyme helps in digesting starch. The liver stores various nutritional substances such as vitamins and iron and others and release them in blood plasma.

What is Pacific ocean?The Pacific Ocean is a body of salt water that stretches from the 60° S parallel in the south to the Arctic in the north, sandwiched between North America and South America on the east and the continents of Asia and Australia on the west.
The Pacific Ocean, which makes up nearly one-third of the earth's surface, is by far the largest of the three major oceans.
Without the South China Sea, it covers over 62.5 million square miles (161.76 million square km). Its area exceeds that of the entire earth's land surface and has twice the area and twice as much water as the Atlantic Ocean, the hydrosphere's next greatest division.

Female mosquitoes need a meal of blood from a person or other animal in order to produce eggs. It has been discovered that mosquitoes have cells on their antennae that can detect the insect repellent known as DEET. The repellent is not harmful to mosquitoes, but when mosquitoes detect DEET, they will not land on the surface where the DEET has been applied. This protects people from being bitten by mosquitoes. Recently, scientists found some mosquitoes that are resistant to DEET because they do not detect its presence. They bred these mosquitoes and eventually produced a population consisting of about 50% DEET- resistant insects. Identify the process most likely responsible for a mosquito initially becoming resistant to DEET.
Answer:
Mutation followed by natural selection made mosquitos resistant to DEET
Explanation:
Natural selection selects beneficial alleles, which increase their frequency in the population, resulting in adaptation. Aptitude, which is the contribution of each genotype to the next generation, increases too.
In many cases adaptations, resulting from the natural selection process can be correlated to environmental factors or selective pressures applied by other organisms or habitats.
Let us remember that, a mutation is a change or alteration in DNI sequences that introduce new variants. Many of these are eliminated, but some of them might succeed and be incorporated into each individual. These mutations are the ones that have been selected by natural selection.
So, in the exposed mosquitos´ example,
The selective pressure or modeling environmental factor is the DEET repellent.Some of the mosquitos mutated changing their behavior. The new mosquito´s response is not-detection of the repellent presence -only in those individuals carrying the mutations-. Natural selection benefits these mutations. Mosquitos survive and become more resistantProbably some of the mosquitos in the population suffered a mutation that favored them in not detecting repellent DEET. These individuals developed resistance to the chemical and were able to survive and reproduce, enhancing population sizes again. Natural selection benefited the mutation that gave them resistance.
Let us remember that the term resistance refers to an inheritable change in the population sensitivity, reflected through the consecutive failure of the chemical effects, correctly used in order to cause an effect on the insect population.
Repellents might produce a genetic modification in the insects, leading them to not detect the chemical. Insects evolve with the capability of tolerating the DEET dose that normally is used to repel mosquitos
The excessive use of DEET leads to the fixation of new genes -by natural selection- that result from mutations in the mosquito genetic material, which makes them become even more resistant to the chemical.

what are the three main particles of soil are? How do these shape and influence the type of soil we observe and its uses?
Answer:
Soil particles vary greatly in size, and soil scientists classify soil particles into sand, silt, and clay. Texture indicates the relative content of particles of various sizes, such as sand, silt and clay in the soil. Texture influences the ease with which soil can be worked, the amount of water and air it holds, and the rate at which water can enter and move through soil. Soil provides plants with foothold for their roots and holds the necessary nutrients for plants to grow; it filters the rainwater and regulates the discharge of excess rainwater, preventing flooding; it is capable of storing large amounts of organic carbon; it buffers against pollutants, thus protecting groundwater.
