What is Diagnostic Process?
Diagnostic Process is the process of determining the disease or condition which explains a person's symptoms and signs. It is commonly called as diagnosis with the medical context being implicit.
Several steps are followed in diagnostic process:-
1. History of symptoms and collecting data.
2. Physical examination.
3. Generating a provisional diagnosis.
4. Testing
5. Reaching a final diagnosis.
6. Consultation
It is a complex transition process which begins with the patient's individual illness history and culminates in a result which can be categorized.

In a nucleic acid polymer, the hydrogen bonds that help to hold regions of double-strandedness together occur between what parts of the nucleotide monomers?.
Answer:
Between opposite nitrogenous base in the complementary strand[tex].[/tex]
Explanation:
The hydrogen bonds, hydrophobic interaction and stacking found in the DNA helps in providing stability to the structure of DNA. Hydrogen bonds are found between the opposite nitrogenous bases of two complementary strands. There are two hydrogen bonds between A and T and three between C and G.
Vasoconstriction is caused by ______ stimulation of vascular smooth muscle and ______ stimulation of vascular smooth muscle causes vasodilation.
Vasoconstriction is caused by sympathetic stimulation of vascular smooth muscle and parasympathetic stimulation of vascular smooth muscle causes vasodilation.
The narrowing (constriction) of blood arteries by tiny muscles in their walls is known as vasoconstriction. Blood flow is delayed or halted as blood vessels close. Vasoconstriction can range from mild to severe. It might be brought on by a sickness, medication, or psychological issues.Norepinephrine's interaction with postsynaptic -adrenergic receptors is the main mechanism by which sympathetic innervation of the peripheral vasculature promotes vasoconstriction. The majority of the body's blood arteries lack parasympathetic innervation. However, salivary glands, gastrointestinal glands, and vaginal erectile tissue are all innervated by parasympathetic neurons, which results in vasodilation. The parasympathetic division causes the body to go into "rest or digest" mode, typically lowering blood pressure and heart rate.Blood arteries often expand in response to parasympathetic stimulation, increasing blood flow but decreasing pressure.learn more about Vasoconstriction here: https://brainly.com/question/4359984

What organelles would a nonphotosynthesis alga need to obtain in order to carry out photosynthesis?
chloroplast organelles would a nonphotosynthesis alga need to obtain in order to carry out photosynthesis
What organelles are required for photosynthesis in an algal cell?Photosynthesis takes place in the chloroplast, a specialised intracellular organelle found in plants and algae, which emerged considerably later. During the day, photosynthesis is carried out by chloroplasts. The photosynthetic cells employ the immediate results of photosynthesis, NADPH and ATP, to create a variety of chemical compounds.
Non-photosynthetic species must rely solely on photosynthesis to obtain the energy they require to exist, which highlights the significance of photosynthesis to them. To continue to exist, all living things must use energy, which ultimately originates from the sun.

How does water having high specific heat capacity and high heat of vaporization help life on earth?.
Having high specific heat capacity and high heat of vaporization helps to sustain life on Earth as heat is absorbed by the water and released slowly, which helps to sustain life.
Water has a specific heat of vaporization. Around 40,000 Joules of energy are required for vaporizing one mole of water. It is due to this heat of vaporization, that water has the ability to store excess heat and release it slowly. Such an effect causes the Earth to tolerate the temperature changes caused by heat from the Sun.
The high specific heat capacity of water helps life on Earth by maintaining ocean temperatures so that aquatic life can survive. As a major part of the Earth is water, hence the specific heat capacity of water absorbs sunlight hence protecting the Earth from high-temperature changes.

Explain how free fatty acid mobilization from the adipose cell decreases during maximal work in spite of the cell being stimulated by all the hormones to break down triglycerides.
Here are the reasons how free fatty acid mobilization from the adipose cell decreases during maximal work in spite of the cell being stimulated by all the hormones to break down triglycerides:
1) The higher H+ concentration, which may inhibit hormone sensitive lipase.
2) The high levels of lactate during heavy exercise.
3) Inadequate blood flow to adipose tissue
4) Insufficient albumin needed to transport the FFA in the plasma
It could be brought on by increased H+ levels, which could inhibit HSL, high lactate levels during vigorous activity, which encourage the re-synthesis of triglycerides, appropriate blood supply to the adipose tissue, or a lack of albumin, which is required to carry FFA in the plasma.

Biology: The purpose of a wetland is to decrease the impact of farm animal waste and nitrogen- and phosphorus-rich fertilizers on the nutrient cycles in water ecosystems. When constructing a wetland, what factors should farmers consider?
In the wetland, ammonia is absorbed by plants or converted to nitrogen gas through volatilization. Nitrification can also occur changing ammonia into nitrites and nitrates. The nitrate form of nitrogen is more readily removed from surface water by wetland plants than the ammonium form.
Wetlands are able to remove nitrogen and phosphorus through a combination of physical, chemical, and biological processes. These naturally occurring processes adsorb/absorb, transform, sequester, and remove the nutrients and other chemicals as water slowly flows through the wetland.
On average, created and restored wetlands significantly reduce the transport of TN and TP in treated wastewater and urban and agricultural runoff, and may thus be effective in efforts to counteract eutrophication.

Choanoflagellates diatoms from kingdom Protista is most closely related to animals.
The choanoflagellates are a class of unicellular and colonial flagellate eukaryotes that live in free-living environments and are thought to be the closest living relatives of animals. Choanoflagellates are collared flagellates; at the base of each flagellum, they have a funnel-shaped collar of intertwined microvilli.The Choanoflagellates are not a varied group of protists, with only 150 species in total. The name "collar-flagellates" comes from the ring of densely grouped microvilli, or thin fingerlike projections, that surrounds the single flagellum by which choanoflagellates both move and take in food. They are tiny single-celled protists that can be found in both freshwater and ocean environments. The collar appears as a single transparent unit in light microscopy because the microvilli are so closely packed, as shown in these illustrations.Therefore, option (b) is correct.
