Answer:

In biology, the active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction. The active site consists of amino acid residues that form temporary bonds with the substrate (binding site) and residues that catalyse a reaction of that substrate (catalytic site).

Explanation:

Enzyme Active Site and Substrate Specificity

Enzymes bind with chemical reactants called substrates. There may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. In some reactions, a single-reactant substrate is broken down into multiple products.

1. Name the two major divisions of the nervous system; list the organs/tissues found in each.

Jet001 [13]

Answer:

1.Structural Divisions of the Nervous System. The nervous system can be divided into two major regions: the central and peripheral nervous systems. The central nervous system (CNS) is the brain and spinal cord, and the peripheral nervous system (PNS) is everything else.

2.Like the nervous system as a whole, the peripheral nervous system also has two divisions: the sensory division and the motor division. The sensory division of the PNS carries sensory information from the body to the central nervous system.

3.Sensory receptors with corresponding stimuli to which they respond.

Receptor Stimulus

Apmullae of Lorenzini (primarily function as electroreceptors) Electric fields, salinity, and temperature

Baroreceptors Pressure in blood vessels

Chemo receptors Chemical stimuli

Electromagnetic radiation receptors Electromagnetic radiation

Electroreceptors Electrofields

Hydroreceptors Humidity

Infrared receptors Infrared radiation

Magnetoreceptors Magnetic fields

Mechanoreceptors Mechanical stress or strain

Nociceptors Damage or threat of damage to body tissues (leads to pain perception)

Osmoreceptors Osmolarity of fluids

Photoreceptors Visible light

Proprioceptors Sense of position

Thermoreceptors Temperature

Ultraviolet receptors Ultraviolet radiation

The burning of solid waste is a major source of energy in industrialized countries.a. Trueb. False

Artemon [7]

Answer:

The statement is false.

Explanation:

Industrialized countries are developed countries which have various sources of energy. In these countries 85% of commercial energy comes from burning fossil fuels, hydropower constitute about 6% of total commercial energy, nuclear power constitutes 5%, biomass, and other sources contribute up to 4%.

In developing countries 58% of commercial energy comes from fossil fuels, biomass contributes 35%, and hydropower contributes 6%. There burning of solid waste is not a major source of energy in industrialized countries.
