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:
Cell wall, chloroplast, and central vacuole
Explanation:
Cell wall, chloroplast, and central vacuole are present in a plant cell but not in the animal cell.
Nucleus, cell membrane, and cytoplasm present in both plant and animal cells.
Oxygen is the answer for this question.
Olds and Milner showed that electrical stimulation of particular brain regions could have a reinforcing effect.
<h3>Electrical brain stimulation</h3>
it is commonly known as focal brain stimulation (FBS), is a type of electrotherapy used in clinical neurobiology and research to activate a neuron or neural network in the brain by either directly or indirectly stimulating its cell membrane with an electric current.
<h3>What is the purpose of brain electrical stimulation?</h3>
- Electrical stimulation can be used to alter how the brain functions because electrical charges are what cause brain activity.
- Brain stimulation has been used to treat stress and mood disorders, and it can even make it easier for people to remember things, solve puzzles, and pay attention.

Answer:
The marine clamworm, Nereis, is carnivorous therefore its digestive system differs from that of the herbivorous earthworm, Lumbricus. The mouth and jaws are retractable (Figure 8, 9). If the jaws are retracted, cut along the midline of the pharynx and pull the jaws out with a pair of forceps.
