I believe when DNA is denatured by heat, hydrogen bonds are separated to create single stranded DNA. When the DNA solution is heated enough, The double stranded DNA unwinds, and the Hydrogen bonds that hold the two strands together weaken and finally break. The process of breaking a double-stranded DNA into single strands is known as DNA denaturation, or DNA melting.
Answer:
In bees, The males (drones) genes are 100% the queen's genes (develops from the unfertilized egg), this is haplodiploid, but the females (workers and queens) have 100% of the father's gene but 50% of the mothers (queen)
Explanation:
In relatedness or diploid, both parents share and pass on a complete set of genes to the offsprings, but for haplodiploidy, all the genes of one parent are passed to the offspring excluding the other parent as in the case of drones to queen bees.
Answer:
Okay so start with diagramming the phases of Mitosis (interphase, prophase, metaphase, anaphase, telophase, cytokinesis) then draw what all the phases would look like for a plant cell. You can search what a plant cell looks like in mitosis and use it as a reference.
Explanation:
the color coding is for drawing each thing in the phases of mitosis

Question :</h2>
Which of the following is not a function of cerebrospinal fluid?
A) acts as a transport medium for waste products
B) provides cushioning for delicate neural tissues
C) provides buoyant support for the brain
D) produces ATP for impulse transmission
E) acts as a transport medium for nutrients
Answer:
D) produces ATP for impulse transmission
Explanation:
CSF doesn't produce ATP for the impulse transmission hence option D is the right option.
Cerebrospinal fluid (CSF) performs following functions :
1) Protects the brain and spinal cord from trauma
2) It supplies nutrients to the nervous tissues
3) It removes the waste products from cerebral metabolism.
For number one, the shadows are longest at sunrise and sunset, and these are different from the ones cast at noon because they are longest and darkest. Hope this helped! I'll probably come back to help with the second one after I do more research :)
