21. When looking at the effect of pH on sucrase activity, what was the wavelength of light
used in the spectrophotometer?
Answer:
540nm
Explanation:
Sucrase is one of the digestive enzymes responsible for the digestion of sucrose containing foods. Its major function is the catalysis of the hydrolysis of sucrose into its subunits; fructose and glucose.
Enzymes, as biochemical catalysts always function maximally at an optimum pH. As the pH of the system departs from the ideal pH for any enzyme, the activity of that enzyme decreases accordingly.
The activity of sucrose is studied using a spectrophotometer of wavelength about 540nm. As the pH of the solution departs from the specific ideal pH of sucrase, its activity decreases as stated above.
What growth information leads to your answer? The colonies are able to grow on minimal medium containing no additional supplements. The colonies are able to grow on complete medium.
Answer:
A growth medium or culture medium is a solid, liquid or semi-solid designed to support the growth of a population of microorganisms or cells via the process of cell proliferation,[1] or small plants like the moss Physcomitrella patens.[2] Different types of media are used for growing different types of cells.[3]
The two major types of growth media are those used for cell culture, which use specific cell types derived from plants or animals, and microbiological culture, which are used for growing microorganisms, such as bacteria or fungi. The most common growth media for microorganisms are nutrient broths and agar plates; specialized media are sometimes required for microorganism and cell culture growth.[1] Some organisms, termed fastidious organisms, require specialized environments due to complex nutritional requirements. Viruses, for example, are obligate intracellular parasites and require a growth medium containing living cells.

10. Write the two likely errors carried out while using ruler during measuring length of anywhy did to like me process carried out while using a ruler during measuring length of any object
Answer:
positive error and negative error.
Explanation:
There are two types of error which is possible when measuring of a length with the help of ruler. Positive error occurs if the calculated value is larger than actual value while negative error occurs when the calculated value is smaller than actual value. To avoid positive error, the increased value should be subtracted from calculated value while negative error can be corrected by adding the value with the reading.

Which two layers are approximately the same age?
core sample 1
core sample 2
Complete question:
Examine the following diagrams. Columns I and II contain rock layers A, B, C, D, E, and F. Both columns were taken from the same dig site at different locations. Which two layers are of approximately the same age? (Note: The diagrams are attached).
Answer:
C and D
Explanation:
Layers C and D apparently contain the same fossilized organisms in the same substrate. Their appearance is very similar. By knowing that certain organisms used to live in a certain period of time, if we find two strata that show the same fossilized organisms, then we can estimate that these two strata are the same age. Fossilized organisms are used to estimate the age of a rocky stratum.
Life history can be illustrated through fossilized organisms trapped or converted into rocks. These fossils are known as index or guide fossils, of animal or vegetal nature, and they can apport information about the rocky stratum in which they are located or incrusted. These fossils are used to determine the age of the rocky sediments or the environmental conditions under which they were deposited.

A research team discovered that a novel hormone X stimulates an enzyme that hydrolyzes proteins in the small intestine. However, when hormone X was added to a test-tube mixture containing the enzyme and proteins, no breakdown occurred.
Required:
a. Why is this the case?
b. Name ONE signal transduction pathway that hormone X is using to transfuse its signal. (write all the steps and intermediates)
Answer:
a. It is a hormone that acts upstream in the signaling pathway (i.e., acting as a ligand by binding to cell receptors)
b. Dopamine-mediated pathways
Explanation:
It is well known that many cellular transduction pathways are activated via binding of signaling molecules (ligands) to receptors capable of triggering signaling cascades into the cell. For example, dopamine is a signaling hormone (neurotransmitter) involved in diverse brain processes (i.e., motor control, emotional response, etc). It is a neurotransmitter that binds to dopamine receptors and then stimulates the enzyme adenylate cyclase in a process that subsequently activates the production of the second messenger cyclic adenosine monophosphate (cAMP). Finally, cAMP acts as an intracellular signal transductor that play roles in many biological processes by transferring into the cell the effects of dopamine.

What is Ependymal cell?
Answer:
Explanation: Ependymal cell is a type of neuronal support cell the forms the epithelial lining of the brain ventricles in the brain and the central canal of the spinal cord ependymal cells similar to all other neuroglia, are derived from a layer of embryonic tissue known as neuroectoderm.
Ependymal cells are ciliated-epithelial glial cells. It develops from radial glia alongside the surface of the ventricles of the brain and spinal canal.
What is the function of Ependymal cells?The main role of Ependymal cells is formation of CSF.
The CSF refers to cerebrospinal fluid. It is done by movement of sodium ion, chlorine ion and bicarbonate ion from blood to ventricles of brain.
Inside ventricles of the brain, collection of ependymal cells and capillaries together i.e., the tela choroidea form choroid plexus, which produces the CSF.
Thus, Ependymal cells are involved in formation of CSF.

In the image, the arrow Is pointing to a celestial object. Which attribute disqualifies the object from being a planet?
A. It appears to have no moons.
B. It is spherical in shape.
C. Its neighborhood is not clear.
D. It has horizontal bands on its surface.
The correct answer is C. Its neighborhood is not clear.
Explanation:
One of the key features of a planet is that it clears its neighborhood; this means the planet gravitational force is strong enough that there are no other celestial bodies on its orbit or next to it except by its moons or satellites. This does not occur in the image presented because there are smaller celestial bodies near to the main or bigger celestial body. This likely occurs if the celestial body is not big enough to clear its neighborhood, and therefore it is not a planet.

When an enzymatic reaction is in progress, do you expect to see an increase, decrease or no change in each of following: (i) substrate (ii) product (iii) enzyme
Answer:
During Enzymatic reaction, enzymes binds to a substrate to form a which then forms the product.
Substrate: A reactant in an enzymatic or chemical reaction is called substrate. Product: The final outcome or substance after completion of reaction is called product.Enzyme: Enzyme helps to increase the rate of reaction and act as a catalyst.Change in shape of substrate, product and enzymes depends on the temperature outside the optimal range which affect bonding between enzyme and substrate. Enzymes definitely changes their size when bind to substrat and the process is called induced fit which increases the rate of reaction.
During an enzymatic reaction, their is an decrease in the concentration of substrate, an increase in the concentration of product, and no change in the concentration of the enzyme.
What is enzymatic reaction?A reaction, which is mediated with the help of an enzyme is termed as enzymatic reaction. A substance, which functions as a catalyst in living organisms and regulate the rate at which the chemical reactions takes place is known as an enzyme.
The enzymatic reactions follows the lock and key model, in which the free enzyme combines with the substrate and forms the enzyme-substrate complex, this is further catalyzed into the enzyme-product complex, from which the free enzyme and product get discharged. The product never further binds with the free enzyme.
In the reaction, the substrate get used up thus its concentration decreases, while the formation of product takes place thus its concentration increases. However, there is no change in the concentration of the enzyme as it does not get used up in the process.
Thus, in enzymatic reaction, substrate decreases, product increases, and enzyme concentration remains the same.
