Answer:
The speed at which the reactants change to products over a given time.
Explanation:
A chemical's <u>reaction rate</u><u> is the change in the concentration of a reactant or a product with time (in moles per second)</u>.
Remember that during a chemical reaction, reactants are converted to products. Or what is the same, products are formed at the expense of reactants. This can be represented:
reactants → products
Therefore,<u> the progress of a reaction can be followed measuring the decrease in concentration of the reactants or the increase in concentration of the products.</u>
According to the temperature and other parameters, the reaction rate can increase or decrease.
Answer:
The correct answer will be option- B and C.
Explanation:
The cellular respiration is the process of forming energy molecules through oxidation of food. The cellular respiration takes place in four stages: glycolysis, link reaction, Krebs cycle and electron transport chain.
The glycolysis converts the glucose molecules to form two molecules of pyruvate and two ATP molecules but the total number of molecules formed in cellular respiration is between 36-38 ATP molecules. The electron flow takes place in the electron transport chain which helps in the generation of the proton motive force used to produce ATP molecules.
Thus, Option-B and C is the correct answer.
Answer:
t(n) = 3·5^(n-1)
Explanation:
The recursive formula describes a sequence in which each term is 5 times the one before it. This is a geometric sequence with common ratio 5 and a first term that is said to be 3.
As you know, the generic formula for a geometric sequence is ...
an = a1·r^(n-1)
For a1 = 3, r = 5, and a sequence named "t", this is ...
t(n) = 3·5^(n-1)
Once energy from the Sun gets to Earth, several things can happen to it: Energy can be scattered or absorbed by aerosols in the atmosphere. ... Light colored surfaces are more likely to reflect sunlight, while dark surfaces typically absorb the energy, warming the planet.
Answer:
1. Evolution can be defined as the gradual development of an organism creating diversity.
2. A common misconception is that Homosapiens are descendants of Apes.
3. analogous structures are features of different species that are similar in function, but not necessarily in structure; such as bird wings and insect wings. homologous structures, however, is an organ or bone with similar underlying anatomical features found in different animals; such as the arms of primates.
4. vestigial structures are structures that have no apparent function and appear to be residual parts from a past ancestor, such as wings of flightless birds.
5. Embryology supports the theory that organisms have a common ancestor in accordance to the theory of evolution.
