Answer: Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
Explanation:
Coal is produced from wood through decayed animals that burry down the earth and also start to deteriorate and behind millions of years they become coal.

If the DNA molecule is only composed of four possible nitrogen bases, how can thousands of different proteins be formed from such a limited set of fixed shapes?
Answer:
nucleotides are only building blocks whose combinations determine different codons which subsequently associate in a sequential manner in order to create different amino acid combinations
Explanation:
A gene is a specific segment of DNA whose (nucleotide) sequence is copied into an RNA during the process of transcription, typically a messenger RNA (mRNA) molecule which is subsequently used to synthesize a protein. During translation, each triplet of nucleotides, i.e., each codon, corresponds to a specific amino acid. There are 64 possible codons (4³: 64), which can combine in different ways to create different amino acid combinations, and thus they are responsible for the generation of a huge amount of proteins coded by a given genome.

What step in photosynthesis may occur during day and night? A.Light independant reactions B.Light dependant reactions c. Photolysis
Answer:
a is the answer
Explanation:
Light independent reactions of photosynthesis may occur during day and night.
STAGES OF PHOTOSYNTHESIS:
Photosynthesis is a metabolic reaction undergone by green plants to obtain their food using energy from sunlight. Photosynthesis is a process that involves two major stages: light independent reactions and light reactions. Light dependent reactions occur strictly under light conditions because light is needed to break down water molecules in a process called photolysis. In the light dependent reactions, water is broken down by light to give oxygen gas. In the light independent reactions, carbon dioxide is required.However, light independent reactions may occur during day and night. This is because light independent reactions does not require light to occur.

Why does sexual reproduction process create offspring with genetic variation (different genes between parents and siblings)?
Answer:
Sexual reproduction process creates offspring with genetic variation because their are 2 parents unlike in asexual reproduction where there's only 1 parent. Since, there are 2 parents with difference in their DNA & genes the offspring too will have a variation.

When an action potential is generated within a motor neuron, ________. When an action potential is generated within a motor neuron, ________. all of the muscle cells within the motor unit are stimulated to relax the muscle cells from a neighboring motor unit will contract every muscle cell of the motor unit is stimulated to contract only select muscle cells within the motor unit are stimulated to contract the muscle cells of the motor unit will occasionally contract
Answer:
every muscle cell of the motor unit is stimulated to contract.
Explanation:
Stimulus in biology can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.
In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ. Therefore, the senses are necessary for behavior because stimuli must be sensed in order to respond.
Stimulus control can be defined as a phenomenon that arises when a living organism responds or behaves in the presence of a stimulus and in another way in the absence of a stimulus.
For example, opening the door of a microwave oven as soon as its timer beeps.
Example II; When your body touches a hot object, you quickly move away and feel some pain subsequently.
Action potentials generates the nerve impulse in a motor neuron.
When an action potential is generated within a motor neuron, every muscle cell of the motor unit is stimulated to contract.
which processes beings the formation of sedimentary rock?
Answer:
clastic sedimentary rock are made up of pieces of pre-existing rocks. pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. if the sediment is very deeply, it becomes compacted and cemented, forming sedimentary rock.
Explanation:
Hope this helped Mark BRAINLEST!!!!
Answer:
Sedimentary rocks are the product of 1) weathering of preexisting rocks, 2) transport of the weathering products, 3) deposition of the material, followed by 4) compaction, and 5) cementation of the sediment to form a rock. The latter two steps are called lithification. A sediment is a particle of solid, loose pieces of rocks (in the form of sand, silt, clay, and gravel), or the remains of living organisms. Sediment is material that has been eroded, transported and deposited by wind, running water, waves, and ice in a place.
These rocks can also form from by the evaporation of seawater, or the settling of the remains of organisms in a water body. Sediment can become compacted, cemented and are foundin layers. Sedimentary rock is often found in layers.
Sedimentary rocks are formed on or near the Earth's surface, in contrast to metamorphic and igneous rocks, which are formed deep within the Earth. The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification.

What is the repeating monomer of a DNA molecule?
triglyceride
O dipeptide
nucleotide
phospholipid
Answer:
3. Nucleotide
Explanation:
The repeating monomer of a DNA molecule is basically called as nucleotide. The correct option is C.
A nucleotide is the DNA molecule's repeating monomer. The building blocks of DNA are called nucleotides.
They are made up of three primary elements: a nitrogenous base (such as adenine, thymine, cytosine, or guanine), a sugar molecule (deoxyribose), and a phosphate group.
Covalent interactions between these nucleotides allow them to join together to form a lengthy chain or strand of DNA. The genetic information is encoded in the nitrogenous nucleotide sequence throughout the DNA strand.
DNA is able to carry and transmit genetic information from one generation to the next due to the specific nucleotide configuration.
Instead of being repeating monomers of DNA, triglycerides, dipeptides, and phospholipids are parts of other macromolecules.
Thus, the correct option is C.
