There are four naturally occurring nitrogenous bases, there are four different types of DNA nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C). This sequence is broken into a series of three-nucleotide units known as codons. Each DNA sequence that contains instructions to make a protein is known as a gene.
Sequencing DNA means determining the order of the four chemical building blocks - called "bases" - that make up the DNA molecule. The sequence tells scientists the kind of genetic information that is carried in a particular DNA segment.
DNA sequencing was built upon earlier knowledge of DNA polymerases and cell-free systems for replicating DNA. The chain-termination method, which makes clever use of a "defective" DNA nucleotide, now dominates DNA sequencing technology.

#SPJ4
Wastewater from power plants are usually dirty and infected with bacteria.
Answer:
cell wall) function:protects and holds the structure of the cell
X for plant cell
chloroplast) absorbs energy from sun through photosyn. to make nutrients
plant cell-x
cytoplasm) a gel like substance in which most of the cell's processes take place
x for plant&animal
ER) packages & transports proteins made by ribosome to the golgi apparatus
GA) transports proteins to their destined location throughout the cell
found in plant and animal cells
Mitch) converts energy in nutrients to usable energy
found in plant and animal cell
nucleus: stores and protects DNA
found in plant and animal cells
vacuole: stores food and water
found in plant and animal cells
HOPE THIS HELPS
Explanation:
Because every second they reproduce
3 examples would be touch, light and chemical.
and the most common signal would be chemical.
