Answer:

   As per my full understanding,

There are two main modes of nutrition:

    Autotrophic – Plants exhibit autotrophic nutrition and are called primary producers. Plants synthesis their food by using light, carbon dioxide and water.

   Heterotrophic – Both animals and human beings are called heterotrophs, as they depend on plants for their food.

              WHEREBY: TERMS IN THIS TWO SETS ARE:

   Chemohetrotroph. Gets energy from chemicals and carbon from other sources.

   Photohetrotroph. Gets energy from light and carbon from other sources.

   Chemoautotroph. Gets energy from chemicals and produces its own carbon.

   Photoautotroph. Gets energy from light and produces its own carbon.

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.

Answer:

like DNA, RNA is made up of nucleotides.There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.

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.

Answer: carbon fixation. Rubisco, by its full name ribulose-1,5-bisphosphate carboxylase / oxygenase, is the key enzyme for the fixation of carbon dioxide CO2 in plant biomass by initiating the Calvin cycle, in relation to the solar energy captured.

Answer:

chloroplasts is the site of photosynthesis in plants ✔️✔️

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:

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities

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:

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.

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)

Amino acids

Explanation:

Since enzymes are proteins, they are made from amino acids. Amino acids are organic compounds.

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.

Answer:

The respiratory epithelium in trachea and bronchi is pseudostratified and primarily consists of three main cell types – cilia cells, goblet cells, and basal cells. The ciliated cells are located across the apical surface and facilitate the movement of mucus across the airway tract.

1) Acid

2) Base

3) Experiment 2

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.
