Answer:
The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released.
Explanation:
The sun is a natural resource used by people. Why is the sun considered a renewable resource? *
the sun goes away at night and then comes back in the morning
on cloudy days, the sun cannot be used
solar energy from the sun is limited
the sun is an unlimited source of energy that isn't used up as fast as people use it
Answer:
Because the earth continuously receives solar energy from the sun, it is considered a renewable resource.

Explanation:
A paragraph is a series of related sentences developing a central idea, called the topic. Try to think about paragraphs in terms of thematic unity: a paragraph is a sentence or a group of sentences that supports one central, unified idea.
Genetic drift says it is a random selection of a genetic variant that causing a change in allele frequency in a population.
One of the best treatment centers for Spinal Muscular Atrophy is located in North Dakota causing migration of SMA carriers into the area at an abnormally high frequency. Thus option B is correct.
What is spinal muscular atrophy?It is a group of autosomal recessive inherited disorders cause progressive muscle degeneration and weakness. One of the second leading neuromuscular disease.
Three types of SMA affect only children of less than 1 year and , type IV and Finkel type observed in adult, Symptoms in adult include weakness in muscles, tremor etc.
Type 1 SMA seen during birth symptoms include difficulty breathing and swallowing, Type II show muscle weakness between ages 6 and 12 months, Type III is juvenile type unable to stand and walk.

2. simple sugars
3. Fats
4. molecular
In a starch molecule, the energy is stored in the bonds between atoms, and the building blocks of this molecule are simple sugars.
Starch is a carbohydrate and a polysaccharide, this means this molecule is composed of dozens of glucose molecules that have formed a chain and it is used by organisms, especially plants to store energy.
In other words, starch is the result of glucose molecules forming a chain, and glucose is considered a simple sugar. Therefore, starch is made up of simple sugars.
On the other hand, the energy in starch can be found in the bonds between atoms. This implies once the bonds between atoms break energy is released, and this energy is used by organisms for multiple activities.

John Needham, Louis Pasteur, and other scientists all performed experiments to disprove ______.
a) spontaneous generation
b) evolution
c) Koch's postulates
d) binomial nomenclature
Answer:
A) spontaneous generation
Explanation:
Spontaneous Generation theory stated that living organisms could be spontaneously generated from non-living matter. Francesco Redi conducted an experiment similar to the one Louis Pasteur would do nearly 200 years later. The 17th-century Italian developed a spontaneous generation experiment that showed that maggots do not spontaneously emerge from decaying meat.
MARK THIS ANSWER BRAINLIEST PLEASE ❤️
The theory of spontaneous generation is an experiment that tries to prove the possibilities that living organisms can be produced from non-living origins.
This experiment was first done by Francesco Redi in 1668. However, several scientists such as John Needham, Louis Pasteur, John Tyndall amongst other scientist tried to disprove the theory of spontaneous generation.
The theory was later disproved by Louis Pasteur and John Tyndall in the mid-19th century.

Say you had the following DNA sequence: ATGCTGCGAAACTTTGGCTGA Let's say there was a mutation that removed one letter (the first C): ATGCTGCGAAACTTTGGCTGA Provide the 6 DNA codons that would be read following the mutation. Are they the same as the original 6 DNA codons that would have been read
Answer:
Codons after the mutation are not exactly the same as before mutation, because one base was deleted, changing the sequence of codons.
Codons before mutation: ATG TGC GAA ACT TTG GCT
Only the first one (ATG) might coincide with one of the codons before mutation.
Explanation:
Genetic information for the aminoacids assembly during the protein synthesis is stored in short sequences of three nucleotides named codons in the DNI or mRNA. Each of the codons represents one of the 20 amino acids used to build the protein. There are a total of 64 codons. 61 codify amino acids, one of these amino acids is also the start point of protein synthesis, and the left three codons are stopping translation points.
The Sequence before mutation ATGCTGCGAAACTTTGGCTGA
Codons: ATG CTG CGA AAC TTT GGC TGA
The Sequence after mutation ATGTGCGAAACTTTGGCTGA
Codons: ATG TGC GAA ACT TTG GCT
Only the first one (ATG) might coincide with one of the codons before mutation.

Answer:
1) GPP is the energy spent staying alive
Explanation:
Gross primary productivity is the energy that is spent by the organism to staying alive because energy is required by the organism for doing activities that is necessary for the survival. Gross primary productivity refers as the rate at which solar energy is captured in sugar molecules during the process of photosynthesis. Producers such as plants use some of this energy for metabolism and cellular respiration as well as some for growth and building tissues.

Secondary is the type of succession that occurs when all of the usable soil has been destroyed in an ecosystem.
What is a succession?Succession is the process of change and development that occurs in an ecosystem over time. It refers to the gradual replacement of one community of plants and animals with another, as each community modifies the physical and biological environment in which it lives. There are two main types of succession: primary succession and secondary succession.
Primary succession occurs in an ecosystem that has no soil or vegetation, such as on newly formed volcanic islands or in areas where glaciers have retreated. During primary succession, the ecosystem must develop from scratch, with the creation of new soil and the establishment of new plant and animal communities. This process can take a significant amount of time.
Secondary succession occurs when all of the usable soil has been destroyed in an ecosystem. This type of succession can occur after a natural disaster, such as a fire or a flood, or after human activity, such as logging or farming. During secondary succession, the ecosystem must rebuild itself from scratch, with new soil being created and new plant and animal communities establishing themselves. This process can also take a significant amount of time, depending on the severity of the disturbance and the conditions of the ecosystem.

How does your model support the claim that
the Northern and Southern Hemispheres
have different seasons?
Answer:
Due to presence on opposite side of the globe.
Explanation:
My model support the claim that the Northern and Southern Hemispheres have different seasons due to present on different location on the globe. The seasons in the Northern Hemisphere are different and opposite of those in the Southern Hemisphere. Seasons occur because Earth is tilted on its axis. This tilting causes summer in one location whereas winter in other location. The Earth's tilt causes the Southern Hemisphere to lean towards the Sun during summer season of Southern Hemisphere while on the other hand, it is winter season in the Northern Hemisphere which leans away from the Sun.
