MITOSIS:
Mitosis is the process by which a single cell produces two daughter cells that are genetically identical to one another. Mitosis is employed by cells for growth and repair. It is the process by which cells are multiplied in the body of an organism. However, mitosis is not involved in the production of gametes or sexual reproduction.

What are the sources of energy for the processes that affect Earth?
Answer: ok so Most of the energy in the Earth system comes from just a few sources: solar energy, gravity, radioactive decay, and the rotation of the Earth. Solar energy drives many surface processes such as winds, currents, the hydrologic cycle, and the overall climate system. Gravity makes rivers and other materials flow downhill and creates tides (from the Moon's gravitational pull). Radioactive decay creates heat in the Earth's interior, while Earth's rotational forces influence currents of air and water.

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.

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.

When working with bacteria, you will --
O only culture known, nonpathogenic bacteria
O only culture pathogenic bacteria.
O dispose of the bacteria by taking them home with you.
O contaminate all cultures.
Answer:
Only culture known, nonpathogenic bacteria.
Explanation:
Pathogenic Bacteria is bacteria that can cause diseases, so if you culture a pathogenic bacteria you could cause an out-break of a disease or illness.
Culturing is the process of basically expanding a bacteria, or making a family that reproduces itself, so you would want a disease or fatal bacteria to reproduce, causing an outbreak.

Which scenario would most likely result in cooperative hunting?
Finches eat grass seeds, but grass seeds are not found in an area during winter months.
A shark eats a certain kind of fish, and the fish swim together when the shark comes close.
Wolves eat rabbits, and the number of rabbits in an area is low.
Lions eat zebra, and there are a lot of zebra and lions living in an area.
Answer:
C. Wolves eat rabbits, and the number of rabbits in an area is low.
Explanation:
Cooperative hunting is a form of animal social behavior that is found common among predators mostly faced with a challenge of effectively finding prey to prey on easily. It involves the cooperation of a group of an animal species that cooperate together to effectively increase their chances of catching preys as well as increase their survival chances in such territories.
A scenario that would most likely result into cooperative hunting is where there are few and limited number of rabbits in an area, and as such, it is difficult to hunt rabbits due to scarcity. In order to increase their chances of catching rabbits, wolves in that area would cooperate together and hunt in packs. This will increase the number of kills they'd make when compared to hunting individually. This ensures there is availability of food to eat and also ensures their survival as a group.

A worm would stand a poor chance of being fossilized because ________.
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.

She wanted to know if there was cotton she could put in her ears because everything was so loud. Where was Julie hit? What is the function of this part of the brain?
Answer:
cerebellum
Explanation:
cerebellum is concerned with the balance and positioning of the body, it receives impulses from the semi circular canals of the ears through the vestibular nerve fibre
I HOPE THIS HELPS.
Cerebellum is the most probable part of the brain which was affected. Julie got hit on the cerebellum which affected her hearing capacity and movements.
What is Cerebellum?
Cerebellum is the part of brain which is located at the back of the head, just above and behind the point where spinal cord connects to your brain itself. Cerebellum is also known as the little brain. It was believed since a long time that cerebellum's job was to coordinate the muscle movements.
The cerebellum is important part of the brain as it adjusts postural adjustments in order to maintain balance. It modulates commands to motor neurons to compensate for shifts in body position or changes in load upon muscles.
The cerebellum is located at the back of brain. Damage to the cerebellum can lead to loss of coordination of motor movement, inability to judge distance and when to stop, inability to perform rapid alternating movements, movement tremors, and staggering.

Explanation:
Portuguese sailors around the southern tip of Africa in 1488 because his voyage showed that the Indian and Atlantic oceans flowed into each other.
Why southern tip of Africa named the cape of good hope?The Portuguese navigator Bartolomeu Dias gave the Cape its original name, the Cape of Storms, in the early 1500s. Later, it was changed to Good Hope to draw more travelers to the southern African coast-passing Cape Sea Route.
The Flying Dutchman supposedly resides at the Cape of Good Hope. The ship is crewed by tortured and ghostly sailors, and according to mythology, it is destined to endlessly beat its way across the nearby waters without ever succeeding in reaching the peninsula.
