Answer:
abiogenesis
Explanation:
a (not) biogenesis (coming from other life forms)
Biogenesis would mean that it's coming from other life forms,
Natural selection is a part of evolution (what is there to select?)
Variation is also a part of evolution (not related)
Which is true about enzymes is: enzymes increase the rate of reactions by lowering the activation energy barrier.
Enzymes are chemical compounds in the form of proteins that act as biocatalysts which function to speed up reactions.
Enzymes work specifically, that is, they can only work on certain substrates by adjusting the shape of the substrate. Enzymes sensor with molecules for substrates to produce compounds through organic chemical reactions that require energy. Some of the reactions assisted by enzymes such as the breaking of large molecules into small ones or the binding of molecules into new molecules. Enzymes can do that because of the influence of the activation energy that every chemical reaction has.
Activation energy is the energy required to break down the reactants. The role of enzymes is to lower the activation energy limit needed to start reactions.

The most widely known HR certifications are the PHR (Professional in Human Resources) and the SPHR (Senior Professional in Human Resources, both sponsored by the Human Resource Certification Institute (HRCI). Visit the HRCI website [https://www.hrci.org/], and answer the following question about the PHR and SPHR certifications.
Which of the following areas of content knowledge is MORE heavily tested (as a percentage of the total certification) in the SPHR (Senior Professional in Human Resources) than in the PHR (Professional in Human Resources)?
Answer:
Business Management and Strategy.
Explanation:
PHR (Professional in Human Resources) and SPHR (Senior Professional in Human Resources) are the human resource management profession. This includes the particular training course period and computer based exam occurs in the world.
This profession mainly teaches about the different strategic approach for the effective Business management and the employees. This helps the business to get advantage in the market. The SPHR demonstrates the mastery in the HR knowledge and provide heavy knowledge of teh business development strategy.
Answer: Cell Membrane, Ribosomes, and Cell wall.
Explanation:
Answer:
<u>All the substrates are bound to the enzyme</u>, thats why the reaction rate stopped increasing.
Explanation:
Actually an enzyme works by binding a substrate molecule to its active site, producing a product , resulting in an increase in the rate of reaction.
Enzyme + substrate = Enzyme + product
Whenever enzymes are added , reaction rate increases as the substrates are being bound to the enzyme's active sites but then occurs a stage where further addition of enzyme cannot increase the reaction rate because all the substrates have bound to the enzyme and <u>there are no substrates left.</u> Hence the reaction rate stopped increasing.
