2. Effect: Earth has a powerful magnetic field- Cause: Iron in earths outer core swirls due to convection currents.
3. Effect: Tectonic plates move- Cause: unstable isotopes in earth release energy.
What is Convection current?Convection currents are defined as the result of differential heating where lighter, less dense, warmer materials rise while heavier, more dense, cooler materials sink. This is the movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the Earth's mantle.
Convection currents arise from differences in fluid density that arise due to a temperature gradient, resulting from the continuous replacement of the hot fluid in the region of the heat source with the nearby cold fluid which is known as the natural convection currents.
Thus, Radiogenic heat released- Cause: convection currents cycle through magma.

Scientific knowledge is always changing. At one time, the kingdom was the
highest level of
classification. Today, the highest level of classification is the domain. Two of
the domains, Bacteria and Archaea both contain microscopic prokaryotic
organisms. What would be the best reason for scientists to separate the
prokaryotes?
A)There were too many species of prokaryotes to only have 1 domain for them.
B)It was determined that neither have chloroplasts.
C)Both organisms do not contain organelles.
D)Research showed differences in living environments.
Answer:
d
Explanation:whater
Research showed differences in living environments is the best reason for scientists to separate the prokaryotes. Therefore, option (D) is correct.
What are prokaryotes?The organisms known as prokaryotes lack a nucleus and other organelles in their cells. There are two distinct groups of prokaryotes: the archaea and bacteria, both of which are thought to have evolved along distinct evolutionary lines.
Prokaryotic organisms or prokaryotes are organisms that lack a true nucleus and membrane-bound cell organelles. Mycoplasma, cyanobacteria, and bacteria are all examples of prokaryotes.
A prokaryotic cell carries out every one of the fundamental roles that an ordinary cell performs. Reproduction, respiration, digestion, and other biological processes are among their capabilities.

Answer:
Condensation is a process in which water vapors changed into liquid state.
Explanation:
Condensation is a process in which water that is present in the vapors form changed into liquid state. Condensation greatly affect Earth systems because this process is responsible for the precipitation on the earth. Condensation occurs in the atmosphere when warm air rises in the atmosphere, cools and unable to hold water vapor. As a result, water vapors condenses to form cloud droplets that falls in the form of rainfall.
why is this conversion of energy from one molecule to another necessary for all cells?
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the energy conversion
=> ATP can be used to store energy for future reactions or be withdrawn to pay for reactions when energy is required by the cell.
=> When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP).

6. Potential energy converts to Kinetic energy and Kinetic energy will convert to
Potential energy. Why does the total energy stay the same? *
The energy is not being created or destroyed: only transformed.
Total energy does not stay the same as some is always lost as heat.
Ο Ο
Energy stays the same because the energy has no where to go but in a system.
Answer:
The total amount of energy and matter in the Universe remains constant, merely changing from one form to another. ... Once the potential energy locked in carbohydrates is converted into kinetic energy (energy in use or motion), the organism will get no more until energy is input again.

What type of energy makes heat
transfer by conduction possible?
A. chemical
B. mechanical
C. kinetic
Answer: C. kinetic
Explanation: On a microscopic scale, conduction occurs as rapidly moving or vibrating atoms and molecules interact with neighboring particles, transferring some of their kinetic energy. Heat is transferred by conduction when adjacent atoms vibrate against one another, or as electrons move from one atom to another.

d) Based on your above answers, do all substitutions cause a change in the amino acid sequence of a
protein? Explain
Answer:
No, they do not all cause a change in amino acid sequence of a protein.
Explanation:
Substitution mutation is the type of mutation that results when the nucleotide base of a gene is replaced by another base in the sequence. A substitution mutation can result into three different types of mutation namely; silent mutation, missense mutation, and nonsense mutation.
- In silent mutation, the nucleotide base that gets replaced by another still forms a codon that encodes the same amino acid as in the original sequence. e.g if guanine replaces adenine in the sequence, TTA to form a mutated sequence, TTG. This mutated codon (TTG) still encodes LEUCINE amino acid just as TTA does. Hence, there is no effect on the resulting amino acid sequence. This portrays that NOT ALL SUBSTITUTIONS cause a change in amino acid sequence of a protein.

What effect does burning fossil fuels during manufacturing and energy production have on outdoor air pollution?
Answer:
It causes global warming as well as air pollution.
Explanation:
Burning of fossil fuels has adverse effect on outdoor air pollution because when the fossil fuels burns carbondioxide gas is released in the atmosphere. Carbondioxide gas is a greenhouse gas which is released in the atmosphere through burning of fossil fuels and is responsible for increasing air pollution. This increase in carbondioxide gas leads to global warming due to blockage of solar radiation that is reflected from the earth surface.
