Answer:

the one with no humidity is going to be taller

The experiments are set to observe and conclude the hypothesis. The level of the humidity is an independent variable, the height of the trees are dependent variable, and the greenhouse is a controlled variable.

The data or the fact that are changed and varied to the need of the experiment is called variable. An independent variable is said to be self-subsistent and results in a cause that affects the other variables. The humidity levels affect the growth.

The dependent variables are not self-sufficient and result in an effect that is varied based on the other variables like the height of the trees is conditional on the humidity level.

The control is constant and does not vary and is independent of the other factors and including the greenhouse which is a factor that is held constant throughout the experiment.

Therefore, the level of humidity is an independent variable.

Solar energy is energy that comes from the sun and is captured by solar cells. These cells transform the energy of photons of light into electrical energy. One mechanism is the energization of electrons, here the energy of the photons is transferred to the electrons, which can already be considered electric energy.

As for the hydroelectric energy, here the waterfalls or rivers flow driving a turbine, which will transform the movement into usable electric energy as it rotates.

Explanation:

40 chromosomes would be found in the sperm produced by heat same squirrel

40 chromosomes would be found in the sperm produced by heat same squirrel.

A chromosome is a lengthy DNA molecule that contains all or a portion of an organism's genetic code. The very long, thin DNA fibres in most chromosomes are covered with packing proteins; in eukaryotic cells, the histones are the most significant of these proteins.

The highest possible level of DNA and protein organisation is seen in chromosomes. Chromosomes' primary job is to carry DNA and pass genetic material from one generation to the next. Cell division involves the critical function of chromosomes. They guard against tangles and damage to the DNA.

For above given example, if 20 chromosomes are present in skin cells, then the squirrel will have 40 chromosomes in the sperm cells.

Thus, 40 chromosomes would be found in the sperm produced by heat same squirrel.

Ammonium sulfate precipitation is commonly used before affinity chromatography to remove contaminants. Blue dextran is used as a non-specific binding control in affinity chromatography. The salt is used to dislodge LDH from the column. There are several possible methods to elute LDH like Changing pH, Gradient elution etc.

a. Ammonium sulfate precipitation is commonly used before affinity chromatography to remove contaminants and impurities from the sample. Ammonium sulfate is a salt that can selectively precipitate proteins based on their solubility. By adding ammonium sulfate to the solution containing LDH, it can cause proteins other than LDH to precipitate out, leaving behind a more purified LDH sample.

b. Blue dextran is used as a non-specific binding control in affinity chromatography. It is not a substrate for LDH, meaning LDH does not bind to it specifically. The binding of LDH to the affinity matrix (BioSepra Blue Trisacryl MR) is achieved through a specific interaction between LDH and ligands immobilized on the matrix. The specific binding properties of LDH to the affinity matrix are usually determined by the choice of ligands that have high affinity and specificity for LDH. These ligands can be antibodies, enzymes, or other molecules that have a high binding affinity for LDH.

To elicit similar binding, other molecules with high affinity and specificity for LDH could be added to the column matrix. For example, specific antibodies against LDH could be immobilized on the matrix to selectively bind LDH.

c. The salt is used to dislodge LDH from the column by disrupting the specific binding interaction between LDH and the ligands on the affinity matrix. The high salt concentration competes with LDH for binding to the ligands, effectively displacing LDH from the matrix. This allows LDH to be eluted from the column and collected in the elution fraction.

d. There are several possible methods to elute LDH from the column in addition to using high salt concentrations. Some common elution methods include:

- Changing pH: Adjusting the pH of the elution buffer to a value that disrupts the LDH-ligand interaction can facilitate LDH elution.

- Competitive elution: Introducing a competing ligand that has a higher affinity for the matrix-bound ligands than LDH can displace LDH and elute it from the column.

- Using chaotropic agents: Chaotropic agents, such as urea or guanidine hydrochloride, can disrupt the LDH-ligand interaction and facilitate LDH elution.

- Gradient elution: Gradually increasing the concentration of a specific eluent (e.g., a salt or organic solvent) in the elution buffer can gradually weaken the LDH-ligand interaction and elute LDH from the column.

The choice of elution method depends on the specific characteristics of the affinity system and the desired purity and activity of the eluted LDH.

Here is a possible plan for investigating the effect of temperature on the rate of digestion of starch by the enzyme amylase:

Hypothesis: Increasing the temperature will increase the rate of digestion of starch by the enzyme amylase.

Equipment and techniques:

1. Microscope and microscope slides

2. Hot plate or incubator to control temperature

3. Stopwatch or timer

4. Starch solution

5. Amylase enzyme solution

6. Water bath to maintain temperature

Justification: The microscope and microscope slides will be used to observe the digestion of starch by amylase. The hot plate or incubator will be used to control the temperature of the reaction. The stopwatch or timer will be used to measure the time required for the starch to be digested. The starch solution and amylase enzyme solution will be used to carry out the reaction. The water bath will be used to maintain the temperature of the reaction.

Health and safety:

1. Wear protective goggles to protect the eyes from splashes

2. Handle the solutions and enzymes carefully to avoid spills or splashes

3. Follow proper laboratory safety guidelines, such as not eating or drinking in the lab

Step-by-step method for data collection and analysis:

1. Set up the microscope and prepare the microscope slides.

2. Prepare several starch solutions with different temperatures, using the hot plate or incubator to control the temperature.

Thyroid hormones are principally concerned with the increase in metabolic rate of tissues that can result in certain effects such as:

A) Increased heart rate

C) Increased body temperature

D) Increased cardiac output.

This is referred to as a chemical messenger which are produced by different types of glands and they are released directly into the bloodstream for action.

They control metabolic reactions and an example is the thyroid hormone which is located in the front of the neck. It controls growth and has other effects on the body such as increase in temperature and heart rate of the individual.

Divergent plate boundaries are formed due to the movement of the tectonic plates. It justifies the formation of the oceanic floors by the plate tectonic theory.

Plate tectonic theory explains the formation of the landforms by the divergent, convergent, and transformation in the plate boundaries.  

The divergent plate tectonic movement causes the formation of the basin ranges as the tectonic moves away from each other and supports the formation of the oceans.

Therefore, the plate tectonic theory supports ocean formation by the divergent plate boundaries.
