Name two types of pathways that help a body maintain homeostasis, and an example of each.
Answer:
Explanation:
The cardiovascular and lymphatic systems transport fluids throughout the body and help sense both solute and water levels and regulate pressure. If the water level gets too high, the urinary system produces more dilute urine (urine with a higher water content) to help eliminate the excess water.
Answer:
The receptor and afferent pathway are pathways that help the body stay n homeostasis. An example of the receptor is like temperatures in your skin. An example of Afferent pathways are sensory neutrons.

How are isobars used by meteorologists?
Answer:
Isobars are lines of constant or equal pressure on a weather map. They can be used to find areas of low or high pressure over a broad area (like the U.S.), and they can tell us how intense the system may be.

Which of the following statements explains the importance of enzymes that check for and repair mistakes during DNA replication?
A
The enzymes replace the DNA with RNA
B
The enzymes speed up the rate of RNA synthesis.
C
The enzymes prevent many genetic mutations from being expressed
D
The enzymes remove many recessive gene copies from the nucleus.
Answer:
C!!
Explanation:
The statement explains the importance of enzymes that check for and repair mistakes during DNA replication is the enzymes prevent many genetic mutations from being expressed. Thus, the option C is correct.
What is RNA polymerase?RNA polymerase is an enzyme that aids in the transcription of DNA into RNA during transcript in the nucleus. The enzymes prevent many genetic mutations from being expressed.
Primase is an enzyme that synthesizes short RNA sequences called primers. These primers serve as a starting point for DNA synthesis during replication as the DNA polymerases cannot begin the synthesis of the new strand, they only extend it after primase begins it and primase produces RNA molecules, the enzyme can be said to be a type of RNA polymerase.
Therefore, The statement explains the importance of enzymes that check for and repair mistakes during DNA replication is the enzymes prevent many genetic mutations from being expressed. Thus, the option C is correct.

Use your knowledge of osmosis to explain why the mass of each cube increased.
Osmosis passes from a medium with a high concentration of water molecules to another with a low concentration of water molecules and since the potato has low water concentration so the water transfers to it increasing its mass
The mass of each potato cube increased because they have gained water by osmosis.
Recall that: osmosis is the movement of water molecules from the region of high water concentration (high water potential) to the region of low water concentration (low water potential) through a semipermeable membrane.
A solution with a high solute concentration will have low water potential and vice versa. They are also said to be hypertonic when compared to a solution with a low solute concentration (hypotonic).
Thus, the potato cubes increased in size because the cells of the potato have low water potential when compared to the distilled water in which they were thrown. In other words, the cell sap of the potato cubes is hypertonic while the distilled water is hypotonic.

Pepsin is an enzyme produced in the stomach. Pepsin has an optimum pH that is very acidic, between a pH of 1.0 and 2.0. In an
experiment involving the enzyme pepsin, the pH is raised from 2 to 11. What will be the MOST LIKELY effect of this on the reaction?
Explanation:
the pepsin enzyme will not be able to work in a basic medium when ph raised from 2 to 11 it's efficiency will be affected and will not be in a condition of digesting protein .
plz mark my answer as brainlist plzzzz.
hope this will be helpful to you .
When the pH is raised from 2 to 11 the most likely effect on the reaction is ;
The rate of reaction will decrease/delayed
Given that Pepsin enzyme has an optimum pH of 1.0 to 2.0, it will perform efficiently as a catalyst in an experiment whose pH levels fall within the range of the optimum pH of Pepsin.
Pepsin enzyme accelerates the digestion of proteins therefore when the pH levels are raised above 2.0 the efficiency of Pepsin enzyme will be negatively affected and the digestion of protein will require a higher activation energy.
Hence we can conclude that When the pH is raised from 2 to 11 the most likely effect on the reaction is The rate of reaction will decrease/delayed.

1.(a) (i) Explain why small organisms such as this amoeba can obtain sufficient oxygen for respiration without a
specialized gas-exchange system.?
fi)explain why the method of gas exchange in (a)i above is only possible in very small organisms.?
Answer:
In single celled organisms surface area to volume ratio is optimum for diffusion/exchange of substances between the cell and its exterior and this rate of exchange suffices the requirement of a unicellular organism. However, in multicellular organisms the surface area to volume ratio is low, the exchange that takes place with the exterior or the environment occurs only through the body surface with the help of a specific structure/organ, example (Skin),However, this exchange does not compensate for millions of cells in a multicellular organism, which have distinct requirements based on their function
Explanation:
i) Amoeba gets oxygen gas dissolved in surrounding water through its plasma membrane by the process of diffusion.
ii)The oxygen gas diffused inside the body is used up by amoeba. carbon dioxide gas is also liberated in the surrounding water through the same process of diffusion.

When measuring the brightness of a star, what is a limitation of using apparent magnitude rather than absolute brightness?
Apparent magnitude does not use the star's color or temperature.
Apparent magnitude is only theoretical, thus its value cannot be directly measured with equipment.
Apparent magnitude does not take into account the fact that not all stars are the same distance from Earth.
Apparent magnitude is only on a comparative scale that determines how bright a star looks from a theoretical distance of 32 light-years from Earth.
Answer:
D. Apparent magnitude is only on a comparative scale that determines how bright a star looks from a theoretical distance of 32 light-years from Earth.

How did the temperature relate to the “recommended temperature limit” (solid horizontal red line)?
Will give extra points for right answer or explanation
Answer:
The “recommended temperature limit” represents limit of the temperature that is good for our world.
Explanation:
The temperature related to the “recommended temperature limit” means that in the graph there is a limit of temperature for our world's environment. if the temperature is between this limit, there is less or no adverse effect on our environment while on the hand, if the temperature exceeds from this limit, then it adversely affected our world because the emission of carbondioxide gas in the atmosphere increases due to this increase temperature..
