a laborer is someone who constantly does physical work which exerts more energy then doing paper work or just work in general in an office so the laborer needs more energy to do the hard physical work then the office worker
Answer:
A labor requires more energy to continuously do work whereas an office worker does work from a single place, the sedentary work environment of an office worker requires less energy and hence less carbohydrates.

Draw a flowchart that explains how Tom’s nervous system controls his actions. As part of the flowchart, write one or two sentences describing how the nervous system is involved in each of these steps:
Tom steps into the haunted house.
Tom feels his heart pumping and his breathing speed up.
Tom jumps when he sees the costumed character.
Tom runs out of the haunted house.
Answer:
Tom’s brain makes a voluntary decision to walk into the haunted house. His brain communicates this message to his skeletal muscles, so he can step inside.
Tom’s sympathetic nervous system causes a fight or flight response, resulting in his increased heart rate and breathing.
Tom is startled when a costumed character jumps out at him. His reaction is a reflex caused by his nervous system.
Tom’s brain makes a voluntary decision to run out of the haunted house. His brain communicates this message to his skeletal muscles.

Protons have a positive charge, electrons have a negative charge, and neutrons have no change. Given
information, if an atom is comprised of 5 protons, 4 electrons, and 5 neutrons, what is the charge (if any)
on this molecule?
A.It does not have a charge because there are equal amounts of neutrons and protons
It needs to lose a neutron and a proton so that all parts of the atom are equal
It has a positive charge because there are more protons than electrons
It has a negative charge because there are more neutrons and electrons than protons

According to US Energy Information Administration data, urban U.S. households own an average of 1.8 vehicles each, compared with 2.2 for each rural household. Urban families also drive about 7,000 fewer miles annually than their rural counterparts, saving more than 400 gallons of gasoline and roughly $1500 at current gas prices. What is one reason for these differences?
Answer:
transportation
Explanation:
looking at nighttime satellite photos that show dark landscapes illuminated by glowing urban dots. On the surface, these seem like clear evidence of city dwellers' oversized energy footprints.
And when comparing big cities and small towns directly, a Philadelphia, Pennsylvania, obviously dwarfs the power consumption of a Philadelphia, Tennessee Urban and rural populations use energy differently, though, which complicates such broad comparisons.
Despite hosting regular traffic jams, cities win the head-to-head efficiency matchup in transportation thanks to their mass transit systems and denser layouts, which promote walking and bicycling. Small-town and suburban residents usually have to drive themselves to get around, which isn't cheap.
According to EIA data, urban U.S. households own an average of 1.8 vehicles each, compared with 2.2 for each rural household. Urban families also drive about 7,000 fewer miles annually than their rural counterparts, saving more than 400 gallons of gasoline and roughly $1,300-$1,400 at current gas prices.

A) worms have been rare during the geologic past
B) worms have no hard parts
C) worms contain no carbon-14
D) all of these
A worm would stand a poor chance of being fossilized because worms have no hard parts.
What is fossil?
An animal or plant from a previous geologic era that has been preserved in the Earth's crust as a fossil, remnant, impression, or trace. The main repository for knowledge regarding the evolution of life on Earth is the complex of information preserved in fossils found all across the world.
Only a small percentage of extinct species have been preserved as fossils, and often only those with a sturdy skeleton are capable of doing so. A calcareous skeleton or shell is present in the majority of major groups of invertebrate creatures (e.g., corals, mollusks, brachiopods, bryozoans).
Other types have silicon dioxide or calcium phosphate shells (both of which are found in the bones of vertebrates). A fast burial following deposition may leave these in a shell or bone.
Therefore, A worm would stand a poor chance of being fossilized because worms have no hard parts.
