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.

When calcium carbonate is heated, it
decomposes into calcium oxide and carbon
dioxide. If 100 g of calcium carbonate are
decomposed, 56 g of calcium oxide is produced.
What would be the mass of the carbon dioxide
given off by the decomposition?
A. 448
B. 110 g
C. 156 g
Answer:
A. 44 g
Explanation:
First, you need to write a balanced equation:
CaCO₃ -> CaO + CO₂
Then, you need to find the molar mass of CaCO₃:
Ca = 40.078 amu
C = 12.0107 amu
3O = 47.9982 amu
_________________
100.0869 amu
Then, you calculate the moles of CaCO₃:
100 g ÷ 100.0869 amu = 0.9991 moles
In the balanced equation, we can see that the molar ratio of CaCO₃ and CO₂ is 1 : 1, so moles of CaCO₃ = moles of CO₂.
Now you need to find the molar mass of CO₂:
C = 12.0107 amu
2O = 31.9988 amu
________________
44.0095 amu
Finally, you can calculate the mass of CO₂ produced:
0.9991 moles * 44.0095 amu = 43.9698 g = 44 g
wirte 2 slogans on 'need to conserve nature?
Answer:

Answer:
Explanation:
1. Save plants, save nature
2. Don't let mother nature become a "once upon time"
b) Describe two measures each to conserve natural vegetation and wildlife, Class 8 - Geography - Unit 1 betwen 90to100 words
Answer:
Afforestation and national sanctuaries are two measures each to conserve natural vegetation and wildlife.
Explanation:
The natural vegetation and wildlife restoration is one of the main concerns that are essential for the development and growth of a country's biodiversity. Due to human land-use changes and migration of people, from one place to another with their cattle, lands are becoming deserted and grassland and forest land are declining.
So, we need to plant more trees that act as the natural habitat for the wildlife and preserve and conserve them in parks and sanctuaries which will help reduce the impacts of global warming and climate change. We should not kill any animal.We should decrease the use of plastics.Sometimes the most practical way to do an experiment is not to perform it in an animal, but to look at cell responses in culture. Cells from mice, humans, and other mammals have been used to establish cell culture lines that have been very important for research. You are studying a novel water-soluble mouse hormone. You know cell culture can be a practical model to reveal protein function, so you apply the hormone to yeast cells, but nothing happens. What is a likely explanation for why nothing happened in your experiment
Answer:
Yeast cells likely do not have receptors that bind to this specific water-soluble mouse hormone
Explanation:
Receptors are molecules capable of binding specific signaling molecules (i.e., ligands). For example, steroid receptors can only bind to specific steroid hormones (e.g. estrogen, progesterone). Plasma membrane receptors are protein receptors that bind to water-soluble ligands. These receptors are embedded in the cell plasma membrane and usually contain several transmembrane domains. Examples of cell membrane receptors include G protein-coupled receptors (GPCRs), enzyme-linked protein receptors and ion channel receptors.
Question 4
What happens to the host cell at the end of the lytic cycle?
the cell breaks open and releases the new viruses
viral DNA combines with host DNA
the host cell divides normally and reproduces viral DNA along with it's own
new viruses are made inside the bacterial cell
Answer:
In the lytic cycle, a phage acts like a typical virus: it hijacks its host cell and uses the cell's resources to make lots of new phages, causing the cell to lyse (burst) and die in the process.

Equilibrium is when the concentration is the same throughout an entire system. Explain how a cell reaches equilibrium in all three types of solutions (hypertonic, hypotonic, and isotonic).
It is pertinent to understand what hypertonic, hypotonic, and isotonic solution means before setting out to explain how a cell reaches equilibrium in each type of solution.
A hypertonic solution is one whose solute concentration is higher than that of the sap of a cell that is immersed in it.A hypotonic solution is one with the same solute concentration as that of the sap of the cell immersed in it.An isotonic solution has a lower solute concentration than that of the sap of the cell immersed in it.In biological systems, water molecules move by osmosis from the region of higher water potential or lower concentration of solutes to the region of lower water potential or higher concentration of solute. An equilibrium is reached when there is no net movement of water between two sides. Hence;
A cell placed in a hypertonic solution will lose water to the surrounding solution until an equilibrium is reached. This means that such a cell will end up shrinking (wilting) or even dying due to loss of water from the cell sap.A cell placed in a hypotonic solution will gain water from the surrounding solution until there is no net movement of water anymore. Such a cell might become turgid or even burst out its cell content.A cell placed in an isotonic solution will neither gain nor lose water because the cell sap and the surrounding solution have equal solute concentrations.More about osmosis here: https://brainly.in/question/1213189

Explain why your model improves upon the student’s original model. How would your model help someone who was learning about photosynthesis for the first time? Plato question
Answer:
Due to inclusion of more steps of photosynthesis.
Explanation:
My model is more advance than the student's original model which provides more information about the process of photosynthesis to the learners by explaining various parts of photosynthesis. My model presents the various steps of photosynthesis in a very efficient way with the help of including some extra parts. The student's original model is not more advance so it can't provides more information about the process of photosynthesis so that's why my model provides more information about photosynthesis.
Answer:
This model shows all the major molecules involved in the Calvin cycle and how they change at each stage of the process. This added detail would clarify that the Calvin cycle is a series of complex steps. The student’s original model didn’t show this breakdown at all, and it shows only the final products. This model also shows the number of each molecule created, which the original model doesn’t do.

Sheets composed of two layers of amphipathic molecules arranged with the hydrophilic groups on the surface and the hydrophobic groups buried in the center that form in water are called A) micelles. B) liposomes. C) vacuoles. D) bilayer membranes. E) none of the above
Answer:
D) bilayer membranes
Explanation:
Two lipidic bilayers compose the cell membrane. There are also proteins and glucans incrusted in between. Lipids are amphipathic molecules with hydrophilic heads -negatively charged phosphate group- and hydrophobic tails. Lipids are arranged with their hydrophilic polar heads facing the exterior and the interior of the cells, while their hydrophobic tails are against each other, constituting the internal part of the membrane. Membranes are fluid, which means that the composing molecules can move through them.
Lipids can easily change places with other neighboring lipids by lateral diffusion in the same layer. This is passive diffusion, which means that it does not need energy to happen.
Lipids can also diffuse transversally to the other layer but not as easily as lateral diffusion. Jumps between monolayers are infrequent as the lipidic polar heads meet the fatty acid barrier.
There are also other lipidic movements as rotational diffusion that imply the rotation of the molecule.

vascular tissues, which enabled them to pull water from the ground and survive on land. Which is most likely
another adaptation that contributed to the success of land plants?
cell walls?
chloroplasts
waxy cuticle
gametes
Answer:
Waxy Cuticle
Explanation:
Waxy Cuticle retains water. It's the closest in terms of surviving on land. For instance, the plants living in water do not need waxy Cuticle to retain or maintain water. The plants on land requires waxy Cuticle because the temperature is hotter than in the water and they are at higher risk of loosing water during hot seasons and climate. waxy Cuticle aids in their water retention allowing them to adapt to live on land.
