Answer:
D) He should get the data peer reviewed and published so other scientists can try to reproduce his results
Explanation:
just did the assignment
The right answer is A) lower the activation energy of chemical reactions.
The enzyme accelerates the reaction without changing the steady state.
Enzymes lower the activation energy of the substrate.
Activation energy or free activation energy is the energy that must be absorbed by the reagents to break their bonds.
The reagents must reach an unstable transition state in which the bonds are more fragile and easier to break.
Even an exergonic reaction requires the absorption of energy to reach the transition state.
Answer:
Evolution
Explanation:
Natural selection is usually defined as a process by which an organism or a specific type of living species adapts to a new environment in order to grow, develop, reproduce and protect themselves from the predators. During this time of migration, evolutionary changes occur in organisms over a specific period of time. It occurs naturally and there are several factors that affect these changes occurring in an organism.
Evolution simply refers to the growth, development, and expansion of an organism that occurs over a definite time period.
Answer:
Embryonic period
Explanation:
The time period of the growth of the baby in the womb of the mother of human is 38 weeks or 9 months.
The time period of 38 weeks is divided into three phases related to the events taking place in that period which are: the germinal period, embryonic period and the fetal period.
- The germinal period lasts from the implantation to the gastrula phase during which the germ layer begins to form that is in the first and second week.
- The embryonic phase begins after the second week and lasts about the eighth week which is marked by the phase of embryonic and differentiation.
Therefore, in the fifth week she is in the embryonic phase of prenatal development.
Answer:
alveoli
Explanation:
They are the smallest structures in our lungs where capillaries exchange O2 and CO2 in blood.
