According to the CDC, tooth decay
affects more than one-fourth of U.S. children aged 2 to 5.Tooth decay is the
damage of the structure of the tooth which is caused by acids that are produced
when sugar is being broken down by plaque bacteria in the mouth. Tooth decay is the primary cause of tooth loss in children in the United
States.
<u>Answer:</u>
The evidence comes from fossils.
<u>Explanation:</u>
Paleontology is the study of the history of life on Earth as based on fossils. Fossils are the remains of plants, animals, fungi, bacteria, and single-celled living things that have been replaced by rock material or impressions of organisms preserved in rock.
I hope this helps!
I think there’s some data missing! Is it possible to have the graphs with the reaction rate please?
The average gene in the human genome is approximately <u>27,000 base pairs</u> base pairs in length.
<h3>What does human nuclear genome contain?</h3>
- One gene. The trypsinogen protein, an inactive precursor to the digestive enzyme trypsin, is synthesized using information from the TRY4 gene.
- Two parts of a gene: These two genes, designated V28 and V29-1, each code for a particular region of the T-cell receptor protein, for which the locus is called.
- Pseudogene one. A pseudogene is a replica of a gene that is not functional and often one whose nucleotide sequence has altered, rendering its biological information unintelligible.
- These are sequences that appear often across the genome.
- The terms LINEs (long interspersed nuclear elements), SINEs (short interspersed nuclear elements), LTR (long terminal repeat) elements, and DNA transposons refer to the four main categories of genome-wide repeats.
- Two microsatellites—sequences in which a brief motif is repeated twice—are involved. The sequence: is found in one of the microsatellites that has the pattern GA repeated 16 times.
5′- GGGGGGGGGGGGGGGGGGGGGGGG
3′-CTCTCTCTCTCTCTCTCTCTCTCTCTCTCTCT-5′
- The TATT sequence is repeated six times on the second microsatellite.
- Last but not least, almost 50% of the 50 kb portion of the human genome that we are interested in is made up of lengths of non-genic, non-repetitive, single-copy DNA that have no known meaning or function.

Answer:
Answer: A and B.
Explanation:
Bulk flow can be described or explained as the movement of molecules or fluids through organisms, i.e plants and animals due to pressure differences. It can also be explained as the combined movement of water and solute due to pressure gradients.
Examples of bulk flow include , the movement of phloem sap in plant, circulatory system in animals.
The importance of bulk flow is that, it makes the movement of molecules possible at the pressure gradient that is beyond that of diffusion.
Note that, bulk flow is also known as the mass transfer or mass flow.
