The ileum ends and the large intestine begins at the ileocecal valve. The vermiform, “worm-like,” appendix is located at the ileocecal valve. The appendix of humans secretes no enzymes and has an insignificant role in immunity.
True or false compared with the other substances water requires a lot of heat to increase its temperature
True. Water has a high specific heat capacity (4.18J/g/K) compared to other substances, thus more heat is required to raise its temperature. This can be explained by water's strong hydrogen bonds.

during the experiment measuring energy production in plants, the highest rate of cellular respiration occurred in
Inferring that the experiment in question seeks to measure the rate of energy production in various stages of plant life, we can conclude that the highest rate will be measured in germinating seeds.
The way in which plants produce energy can vary between the species of plants as well as the stage in the plant's life cycle. In broad terms, plants produce energy through cellular respiration.
Cellular respiration is the process by which cells use oxygen or other nutrients and turn it into an energy molecule known as ATP through a series of metabolic reactions. In plants, this occurs in the chloroplasts.
Once the required environmental conditions are met a seed begins to germinate. When this occurs, the seed begins to:
Absorb increased amounts of waterMobilize nutrient reservesGrow rapidly.All of these will require energy molecules to complete. This rapid and sudden increase in the amount of energy required explains why the highest rate of energy production will be measured in germinating seeds.

Explanation:
The figure below shows what happens to the pH of two solutions when an acid is added. Use the key above the image to answer the questions about the image.
1) Acid
2) Base
3) Experiment 2
Explanation:1) In Experiment 1, when the acid is added, the color of the solution goes from light (suggesting base) to dark (suggesting acid). As such in this case, adding the acid resulted in an ACIDIC solution.
2)The opposite is true in Experiment 2. When the acid is added, the color remains light (suggesting base). As such in this case, the resulting solution is BASIC.
3) Experiment 2 is when the acid is added to buffer the base. A buffer solution, as you remember, is a solution the resists changes to pH when an acid or base is added. Since the addition of the acid in Experiment 2 was done so the pH doesn't change as drastically as in Experiment 1, then we can conclude that it was done to create a buffer solution.
I hope this helps. Let me know if you need any clarification. I am happy to provide it.
A buffer solution is one that can resist changes in pH when an acid or base is added to it.
In Experiment 1, adding an acid to a basic solution would likely result in the solution moving closer to neutral or becoming less basic. So, it might still be slightly basic but less so.
In Experiment 2, adding an acid to a basic solution would likely result in the solution moving closer to neutral or becoming less basic, similar to Experiment 1.
From the information given, it's not possible to definitively determine in which experiment the acid is added to a buffered base. However, a buffer solution is one that can resist changes in pH when an acid or base is added to it. If either of the experiments involves a solution that shows a relatively small change in pH upon adding the acid (compared to what would be expected without buffering), that could be an indication that the acid is being added to a buffered base.

Is the carbon used in photosynthesis balanced by carbon given off by cellular respiration?
Answer:
Yes.
Explanation:
Plants absorb the CO2 from the air (which we breathe out CO2) and break it into carbon and oxygen. They use that carbon as well as water from the soil to create glucose and ATP and release the oxygen for us to breathe and then we breath the oxygen in and use cellular respiration to create CO2 and energy from the oxygen and our food. It then goes back through the cycle.

Answer:
nucleolus
Explanation:
The nucleolus is a region found within the cell nucleus that is concerned with producing and assembling the cell's ribosomes. Following assembly, ribosomes are transported to the cell cytoplasm where they serve as the sites for protein synthesis. Within the cell nucleus there's a very specific part called the nucleolus. This does not contain the chromosomes. What this contains is the machinery necessary to assemble the cell's ribosomal RNAs.

A spring with a spring constant of 5 N/m is stretched by John until extended by 1 m. How much elastic potential energy is stored by the spring?
Answer:
0.719m
Explanation:
if the load/ deflection curve of the spring has Force (N) on the y axis and Deflection (m) on the x axis then the slope of the curve is 85 N/m
The energy is the area under the curve ie Base x Height/2
Area (22) = Deflection x (Deflection x 85) /2
Therefore, Def = Sqrt(22 x 2 /85)
Answer:
2.5J
Explanation:
Elastic potential energy = ½ ke²
½ x 5 x 1² = 2.5

The solute potential of a plant cell is -10 bar, and its pressure potential is 3. The plant cell is placed into a solution with a water potential of -10 bar.
What is the water potential of the cell, and in which way will water move?
The water potential of the cell would be -7 bar and thus, water will move from the cell to the surrounding solution.
Recall that:
Water potential = pressure potential + solute potential
For the plant cell, solute potential = -10, pressure potential = 3
Water potential of the cell = 3-10
= -7 bar
The water potential of the cell is -7 bar while that of the surrounding solution is -10 bar. Thus, the cell has a higher water potential than the surrounding solution.
Recall that water usually moves from the region of high to the region of low water potential. Therefore, water will move from the cell to the surrounding solution.

2. How does the structure of DNA
help account for the way in which DNA copies itself?
Answer:
What happens during each stage of the cell cycle?
The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.
