What renal actions does angiotensin II have that are not related to its ability to produce vasoconstriction
Answer:
Angiotensin II is a main effector of RAS and is produced due to the release of the renin that forms in the kidney, angiotensin in turn stimulates the release of aldosterone from the adrenal cortex.
Angiotensin II serves various roles other than vasoconstriction to maintain blood pressure that are:
1. Autoregulation of GFR
2. Reduction of salt excretion through direct and indirect actions on renal tubular cells,
3. Growth modulation of renal cells - these express AT1 receptors.
Chang wants to build a circuit that will light up a bulb from a flashlight, and has a battery, switch, wire, and a light bulb.
Which component would Chang use as the source of energy?
the battery
the switch
the wire
the light bulb
The battery component would Chang use as the source of energy.
What is Battery?Batteries consist of one or more cells, each of which undergoes chemical processes to produce an electron flow in a circuit.
Each battery has three primary components: an anode (the "-" side), a cathode (the "+" side), and an electrolyte of some sort.
When the cathode and anode of a battery are connected to a circuit, a chemical reaction takes place between the anode and the electrolyte. Following this reaction, electrons return to the cathode and experience a second chemical change.
Therefore, The battery component would Chang use as the source of energy.

Explanation:
How are all fungi and all protists alike?
Explanation:
Since plants and fungi are both derived from protists, they share similar cell structures. Unlike animal cells, both plant and fungal cells are enclosed by a cell wall. As eukaryotes, both fungi and plants have membrane-bound nuclei, which contain DNA condensed with the help of histone proteins.

2 difference between pupa of honey bee and pupa of silkworm??
The larvae of a silk moth secrete the silk thread which is used to make clothes. Honey bees produce and store honey which is nutritious food. Silkworm is a creamy white colored insect which is about 2-3 cm long and shining in nature. Bee larvae have been shown to be an excellent food source for rearing insects

How do superantigens enable pathogens to hide from the immune system if they actually stimulate the immune system? They cause the immune system to produce an exaggerated response, distracting it from the actual pathogen. They cause fever, which destroys the complement proteins. They cause the immune system to destroy IgA antibodies. They cause the immune system to turn on itself.
Answer: They cause the immune system to produce an exaggerated response, distracting it from the actual pathogen.
Explanation:
Superantigens are a type of bacteria that suppress the immune system by excessively activating it. They cause the creation of non-specific T-cells which then causes the body to look for other organisms apart from the pathogen.
With the immune system distracted, the pathogen then infects the body thereby making these pathogens particularly dangerous.
Why do you think sea otters are important in the kelp forest?
Answer:
It controls the population of sea urchins.
Explanation:
Sea otters are very important in maintaining the balance of ecosystems present near the sea or ocean, such as kelp forests etc. In the absence of sea otters, sea urchins can increase in population i.e. overpopulate the sea floor and feed all vegetation of the kelp forests that provide cover and food for many other marine animals which leads to imbalance of an ecosystem so that's why we can say that sea otters are important in the kelp forest.

As you know, coronaviruses, influenza viruses, measles viruses, and rhinoviruses all encode RNA-
dependent RNA polymerases. All four of them introduce this gene into host cells. Two of them
ALSO introduce the RdRp enzyme. Which two? Why MUST they carry the polymerase protein in the
virus particle?
Answer:
In order to form more DNA molecules.
Explanation:
These viruses carry the polymerase protein in the virus particle because this protein synthesizes DNA molecules from deoxyribonucleotides. This formation of DNA molecule enables the virus cell to increase in their population. Each and every new cell of virus requires DNA molecules so we can say that this polymerase protein is very important and necessary for virus.

Allosteric effectors: Question 1 options: can lead to a decrease in the availability of a protien alter enzyme activity by binding to the active site of an enzyme can cause large changes in enzymatic activity decrease the sensitivity of the enzyme at nearly all concentrations of substrate do not alter the sensitivity of a metabolic pathway
Answer:
can cause large changes in enzymatic activity
Explanation:
An enzyme refers to a biological catalyst that is typically used to speed up (accelerate) the rate of a chemical reaction by lowering the activation energy of its reactants.
An allosteric effector can be defined as an agent, organ or molecule that is being binded to an enzyme at a site, thereby causing a reduction (negative effect) or an increase (positive effect) in an enzyme activity.
When the activation energy of a reaction is low, the rate of the reaction would be faster. Therefore, an enzyme speeds or catalyzes the rate of a reaction by lowering its activation energy.
Additionally, if the conditions are not optimal for an enzyme, it limits the ability of an enzyme to bind or be joined with its substrates.
Furthermore, an increase in temperature increases or speeds up the rate of a reaction while low temperature limits or reduces the rate of a reaction.
In the human body, the optimal temperature for enzymes is around 37 degrees celsius (°C).
In conclusion, an allosteric effector can cause large changes in enzymatic activity because it acts as an intermediary and mediates specific effect in a metabolic pathway.
