If the magnification of the microscope is increased, then the visibility of the cell organelles under a microscope would be clearer and more distinct
Answer:
An endospore may survive a drought because it is protected by a THICK WALL
Explanation:
An endospore is a structure that is produced by some bacteria. This structure possesses characteristics such as:
a. Endospores have thick walls
b. They are very resistant and resilient to changes in temperature.
c. They are resistant as well to the action or activity of some chemicals.
d. Endospores serves as a means of protection for microorganisms such as Bacteria.
e. Endospores do not reproduce.
f. Endospores can be dormant or Inactive for a very long period of time.
Endospores may survive drought, activity of chemicals, extreme weather conditions, extreme temperatures due to the presence of thick walls in their structure.
Answer:
Latitude on the equator is 0 degrees and longitude is 180 degrees.
If this helps, please give me brainliest.
Answer:
a) The response indicates that a pH below or above this range will most likely cause enolase to denature/change its shape and be less efficient or unable to catalyze the reaction.
b)The response indicates that the appropriate negative control is to measure the reaction rate (at the varying substrate concentrations) without any enzyme present.
c)The response indicated that the enolase has a more stable/functional/correct/normal protein structure at the higher temperature of 55°C than at 37°C because the enzyme is from an organism that is adapted to growth at 55°C.
Explanation:
Enolase catalyzes the conversion of 2-phosphoglycerate to phosphoenolpyruvate during both glycolysis and gluconeogenesis.In bacteria, enolases are highly conserved enzymes and commonly exist as homodimers.
The temperature optimum for enolase catalysis was 80°C, close to the measured thermal stability of the protein which was determined to be 75°C, while the pH optimum for enzyme activity was 6.5. The specific activities of purified enolase determined at 25 and 80°C were 147 and 300 U mg−1 of protein, respectively. Km values for the 2-phosphoglycerate/phosphoenolpyruvate reaction determined at 25 and 80°C were 0.16 and 0.03 mM, respectively. The Km values for Mg2+ binding at these temperatures were 2.5 and 1.9 mM, respectively.
Enolase-1 from Chloroflexus aurantiacus (EnoCa), a thermophilic green non-sulfur bacterium that grows photosynthetically under anaerobic conditions. The biochemical and structural properties of enolase from C. aurantiacus are consistent with this being thermally adapted.
Answer:
Play Therapy
Explanation:
Play therapy is a type of psychotherapeutic orientation by which play is used as a medium to help an individual, most especially children, to express their feelings. This therapy helps with the brain development of a child and enables a play therapist respond to the needs of a child, most especially the metal health needs.
Through play therapy, a child is naturally able to communicate his feelings as he is guided, and this helps children to become aware of themselves ad accept who they are.
