<span>The two sentences that accurately describe the girls' experience with heat transfer are "Camille heats a rock in the campfire for 30 minutes, and then removes it with tongs. She greases the rock and lays the bacon strips directly on it." By heating the rocks in the campfire and laying the bacon on the rocks, the girls transferred the heat from the fire to the rocks, and the heat from the rocks to cook the bacon.</span>
Answer: Homologous chromosomes are the pairs of chromosomes that having same gene sequence, equal length of arms and centromere location. Homologous chromosomes have two homolog one come from male parent and other come from female parent.
Explanation:
These chromosomes Are formed for the purpose of genetic variations. They are called homologous because when two same structured exist it form pair together
RNA and DNA-RNA hybrids are more dense than simply DNA if the density of different nucleic acids is tested using a CsCl gradient.
The primary technique employed in molecular biology is the extraction of DNA, RNA, and protein. Scientists can separate materials according to size, shape, and density by using density gradient centrifugation. Isopycnic centrifugation, a sort of density gradient centrifugation that Meselson and Stahl developed, employed a cesium chloride solution to separate DNA molecules solely on the basis of density. Because DNA has hydrogen bonds between its strands, which makes it less dense than RNA, RNA has a far larger density than DNA. RNA can be obtained at the test tube's bottom using a CsCl density gradient and high centrifugation, whereas DNA can be recovered in the middle layer.

Answer:
(B) Energy released from the chemical reaction is used to directly phosphorylate ADP.
(D) Energy released from the chemical reaction is used to directly reduce NAD+
Explanation:
phosphorylation is a addition of phosphoryl group to an organic compound.Substrate level phosphorylation is a process where there is ATP is produced from ADP by transferring a high energy phosphate group from phosphorylated metabolic compound.This process occurs in glycolysis and citric acid cycle.and this pathway is exergonic pathway
