b. enzymes increase the activation energy of reaction.
c. Temperature and pH can affect how enzymes Work .
d. Many different types of substrates with different shapes can bind to a single enzyme
The best answer is c - temperature and pH can affect how enzymes work.
Enzymes are active only within a narrow pH range. The most favorable pH , the point where the enzyme is most active is called the optimum pH. Extremely high or low pH outside the optimum generally results in complete loss of activity for most enzymes.
Enzymes are also most active at a specific temperature called optimum temperature.
Temperatures significantly below the optimum slow down enzyme activity while those significantly above the optimum may denature the enzyme, causing permanent and irreversible damage.

A) Inconsistent units of measure
B) Insufficient amount of data
C) Duration of the study
D) Number of samples
Answer: A. Inconsistent units of measure
Explanation:
When taking data such as measurements, it is very important that the results are reported in the same unit of measure. Failure to do so will eventually affect your analysed result.
Answer:
A) Inconsistent units of measure
Explanation:
Since Courtney measured the same variable in all the tagged tendrils, the unit of measurement is supposed to be the same. Before any further processing or analysis of the data, she will need to use the appropriate conversion factors to convert all the variates to the same unit.
The research lasted for a whole year and data were collected weekly, the issue of insufficient data or duration of study does not arise in this case. Also since, the size of study population was not indicated, it will be be difficult to point out the sample size as an issue.
The correct option is A.
Answer:
The correct answer would be the virus envelope.
Viral envelope is a protective covering present around the capsid proteins in some viruses.
It is usually derived from the cell membrane of the host and thus it is composed of lipid and viral proteins.
It provides stability to the viral particle, helps in protecting the viral genome, and aids in the fusion of the virus with the membrane of the host.
Examples of viruses in which envelope is present: herpesviruses, poxviruses, flavivirus, hepatitis D et cetera.
Examples of viruses in which envelope is absent: adenoviridae , papillomaviridae , picornaviridae , caliciviridae et cetera.
