Explanation:
Animal cells are considered eukaryotic and bacteria cells prokaryotic. This is because -
1. animal cells grow at a much slower rate than bacteria cells..
2.the cell membrane on an animal cell is much more rigid.
3.animal cells require energy from outside food sources.
4 .the genetic material of animal cells is stored in a nucleus.

Which statement is a false statement about a hydrothermal vent?
A.
Cold water flows from hydrothermal vents and is warmed by the surrounding water.
B.
Eight-foot long worms and blind fish may live near a hydrothermal vent.
C.
Hydrothermal vents can eventually close up.
D.
Minerals and gases may cause black smoke to flow from a hydrothermal vent.
Answer:
"Extremophiles" are organisms with the ability to thrive in extreme environments such as hydrothermal vents. Since they live in “extreme environments” (under high pressure and temperature), they can tell us under which range of conditions life is possible.
Through advances in engineering and technology, scientists have been able to explore new habitats and
discover new life forms and metabolic strategies. Most ecosystems on Earth are sustained by photosynthesis at the base of the food chain. Hydrothermal vent
ecosystems are powered by a process called chemosynthesis that produces energy from chemical reactions.
Like photosynthesis, chemosynthesis results in the production of sugar and other organic compounds through
the fixation of CO2, but it uses chemicals like H2S as the energy source rather than sunlight.
Symbiosis is a close, long-term interaction between two or more different species of organisms. In some
cases, both species benefit from the symbiotic relationship.

Write 3 Examples of Chemical weathering and Physical weathering
Answer:
Physical Weathering-
Swiftly moving water. Rapidly moving water can lift, for short periods of time, rocks from the stream bottom. Ice wedging. Ice wedging causes many rocks to break. Plant roots. Plant roots can grow in cracks.
Chemical Weathering-
The reaction of carbon dioxide gas in rainwater can produce carbonic acid that dissolves some minerals, especially limestone. Acid rain caused by pollution such as factory and car exhaust is another agent of chemical weathering. Chemical weathering also occurs when iron in rock oxidizes or rusts.

Weathering can be defined as breaking down rocks into smaller rocks by the effects of agents of erosion, chemical agents, and physical agents.
Examples of chemical weathering: Carbonation, Hydrolysis, and Oxidation
Examples of physical weathering: Expansion due to the effects of heat, Abrasion, Freezing
Chemical weathering can be defined as the breaking down of rocks due to chemical reactions. This affects the chemical composition of the rocks.
Physical weathering can be defined as the effects of physical agents on rocks such as wind, temperature e.t.c that result in the breaking down of rocks. In Physical weathering, the chemical components of the rocks do not change.
Examples of chemical weathering are:
Oxidation: The breaking down of rocks due to the effects of oxidationHydrolysis: The dissolving of the mineral components of a rock due to its interaction with water.Carbonation: This is the reaction between the rock and acidic rain which contains carbonic acid.Examples of physical weathering are:
Expansion due to the effects of heatAbrasion: When rocks come in contact with other rocks, this can lead to physical weathering.Freezing thawing: When water gets frozen in rocks, when the ice starts to melt(thaw) the results in the breaking down of rocks as well.To learn more, visit the link below:

False
Answer:
true
Explanation:
Seamounts occur when magma breaks through the Earth's crust.
True
or
False
Answer:
true
Explanation:
Pick TRUE or FALSE for the following statements:
1. There is a chemical difference between the gaseous and liquid state of the same substance
2. Liquids have a fixed temperature, but no fixed shape
3. Molecules of ice have less mass than molecules of water
4. A plasma is a gas with an electrical charge
all false except for the last one
The phases of matter include liquids, solids, and gases. The last phase of the matter called plasma contains charged particles. Thus, statements 2, 3, and 4 are true, but 1 is false.
What are phases of matter?The matter is made of particles that are arranged differently to form the various states of matter. The gases, solids, and liquids differ in their physical arrangement and not the chemical that makes them different from each other. Thus, statement 1 is false.
Liquids have no fixed shape but definite volume due to the free particle arrangement. The mass of the water is more than that of the ice as they have high density than a solid substance. Thus, statements 2 and 3 are true.
The other form of matter called plasma is said to carry charges in the form of electrons and ions that make it different from the other states and has a form similar to the gases. Thus, statement 4 is true.

Heat transfers from an area of ____temperature to an area of ___ temperature.
Answers:
A. low to high
B. high to low
C. high to high
D. it can travel high to low and low to high
Answer:
b. high to low.
heat dissipates, spreads out.
The transfer of heat takes place from the region of high temperature to the region of low temperature.
What is heat transfer?It is a mechanism or phenomenon, which convey entropy and energy from one location to another. In order to attain thermodynamic equilibrium, the transferring of heat takes place from the warmer object to the cooler object.
The transferring of heat always takes place from the object at the higher temperature to the object with the lower temperature. The heat transfer in case of a gas is associated with a change in temperature.
Thus, the correct answer is option B, that is, high to low.

1. What is the main function of the skeletal system and how is itstructured?
2.What are the main organs in this system
Answer:
1.The skeletal system works as a support structure for your body. It gives the body its shape, allows movement, makes blood cells, provides protection for organs and stores minerals
The skeletal system includes the bones of the skeleton and the cartilages, ligaments, and other connective tissue that stabilize or connect the bones. In addition to supporting the weight of the body, bones work together with muscles to maintain body position and to produce controlled, precise movements.
