Answer:
Solar and geothermal energy are both considered renewable energy sources. ... Nuclear energy produces nuclear waste, while solar and geothermal energy do not produce a significant amount of waste.
In Sanger sequencing, once a modified nucleotide is incorporated into the DNA, there is no free 3'OH group to attach the next nucleotide being added. This phenomenon is useful to sequence a polynucleotide chain.
Dideoxynucleotides (ddNTPs) are nucleotide inhibitors of the DNA polymerase, it is for that reason that they are used in Sanger sequencing.
The ddNTPs are similar to natural deoxynucleotides used by cells during ADN replication; however, ddNTPs lack a hydroxyl (OH) group on the 3’ carbon of the deoxyribose.
In consequence, once a ddNTP is added, DNA synthesis cannot progress, thereby this phenomenon can be used to determine the order of nucleotides during the elongation of a polynucleotide DNA chain.

Answer:
<h2> Saving
the Green Sea Turtle</h2><h3> Cheyanne Faith Ybarra</h3>
The green sea turtle, also known as the green turtle, black turtle, or Pacific green turtle, is a species of large sea turtle found in warm subtropical and tropical ocean waters. The green sea turtle is an endangered species and its population number decreases every year. Recent estimates show us that there are 1.5 million green sea turtles worldwide, and only 300,000 remaining in the Caribbean. Researchers estimate that 4,600 green sea turtles perish each year because of fishing gear, poachers, vessel strikes, loss of foraging habitat, entanglement in or ingestion of marine debris, and the harvesting of their eggs. We can stop the green sea turtles from going extinct by making fishing gear safe for the turtles, staying away from their nesting areas, protect them from poachers, stop the harvesting of their eggs, and keeping the oceans and beaches clean so there is nothing to strangle or poison them. These are just a few ways people can help save the green sea turtles from going extinct.

This statement - some forms of chromatin modification can be passed on to future generations of cells about the modification of chromatin structure in eukaryotes is true
Eukaryotes are organisms whose cells have membrane-bound organelles in addition to a nucleus. Eukaryotic creatures come in a great variety, including most algae, all animals, plants, fungus, and protists. Eukaryotes can have a single cell or many cells.
Prokaryotes are organisms consisting of cells that don't have cell nuclei or any organelles that are enclosed in membranes. Eukaryotes are organisms composed of cells with membrane-bound organelles and a nucleus that contains genetic material.
Since prokaryotic cells lack a membrane-bound nucleus, eukaryotic cells are the main difference between these two types of creatures. Eukaryotes store their genetic material in their nuclei.
