Which of the following terms means a group of connected or related objects or materials

Which of the following statements is FALSE?

Delvig [45]

Answer:

c. Damage to the primary (somatic) motor cortex results in the loss of both voluntary muscle control and all reflexive contractions.

Explanation:

The primary motor cortex is an area in the brain that is responsible for the control and regulation of activities that involves movement of the body as well as the postures they body takes which we also refer to as motor skills.

The primary motor cortex sends signals in the form of nerve impulses to the brain and this in turn helps in the maintenance of the motor skills that is carried out by the body.

Not only does the damage to the primary (somatic) motor cortex results in the loss of both voluntary muscle control and all reflexive contractions, it also causes other losses such as constant contraction of the muscles also know as spasticity, involuntary muscle contraction also referred to as clonus.

How is enthalpy used to predict whether a reaction is endothermic or exothermic?

Radda [10]

Answer:

$329.48 KJ/mol$ heat is released by the combustion of $2 mol$ of methane

Explanation:

The value of enthalpy determines whether the reaction is exothermic or endothermic. If the enthalpy change is positive, then the reaction is endothermic (heat or energy released) and if the enthalpy change is negative then the reaction is exothermic (heat or energy absorbed).

$2CH_4(g)+4O_2(g) => 2CO_2(g)+4H_2O(g)$

$\Delta H \ reaction=[ 2(\Delta HfCO_2)+ 4(\Delta HfH_2O)]-[2(\Delta HfCH_4)+4(\Delta HfO_2)]$

= $2 ( -(393.5 KJ)/mol)-[2( -74.6 KJ/mol)+4(-241.82 KJ/mol)]$

$= -787 KJ/mol-[ -149.2 KJ/mol-967.28 KJ/mol]$

$= -787 KJ/mol+1116.48 KJ/mol$

$=329.48 KJ/mol$

In this question, the enthalpy of formation has positive value and hence the reaction is endothermic in which the heat is released.

What is the chemical reaction used to study enzyme activity in the lab (lactase breaking down lactose into its monomers). Know t

Bas_tet [7]

Answer: The chemical reaction in this example is Called hydrolysis in the presence of Lactase

Here is a word equation for the hydrolysis of lactose:

lactose + water → galactose + glucose

Explanation: The equation is called <hydro> + <lysis) of these terms refer to water and splitting respectively. So hydrolysis means splitting with water. Enzymes pull out a monomer by examining where the monomers are connected, and placing a water molecule in between them, resulting in the breakage of the bond between the monomers. Here are two picture to represent it.
