Answer:
A. CRISPR sequences in bacteria resemble those from bacteriophage and plasmid DNA. (The CRISPR sequences are derived from previously invading bacteriophages and pladmids.)
B. For reverse genetic studies, CRISPR /CAS can be used to replace wild type alleles with mutant alleles which can knock out the function of target genes. (CAS 9 introduces double strand break (DSB) in the target sequence which is then repaired by non homologous end joining (NHEJ). NHEJ causes deletion, insertion or frame shift mutation leading to knock out of the target genes.)
C. CRISPR is a bacterial sequence in the bacterial chromosome. ( The sequences are derived from bacteriophages that had infected the bacteria defore.)
D. The guide RNA guides CAS to specific DNA sequences. ( The guide RNA directs CAS nuclease to the target sequences for editing.)
E. The CRISPR/CAS system was discovered in bacteria, and it's natural function is the equivalent of an immune system in bacteria for remembering viral infections and for attacking viral DNA in future infections. (The CRISPR/CAS system provides acquired immunity to bacteria.)

Answer:
With the inhibition of cyclic AMP phosphodiesterase in that cell, Kinase A will not be inactivated, so phosphorylase kinase will remain active.
Explanation:
Phosphodiesterase is an enzyme that has the function of hydrolyzing cAMP by converting it to AMP. As a result, a protein called kinase is inactivated and lipids break down in fat metabolizing cells. CAMP is a cellular messenger.
Cyclic AMP phosphodiesterase, in turn, is an enzyme that catalyzes the conversion of cyclic AMP into a different molecule. as a result, a molecule called kinase A is deactivated. However, if inhibition of cyclic phosphodiesterase AMP in a muscle cell stimulated by adrenaline, Kinase A will not be deactivated, so phosphorylase kinase will remain active.
Answer:
for a fossil to form, an organism must be buried quickly so that any oxygen is cut off and its decay slows down or stops. ... Fossil formation begins when an organism or part of an organism falls into soft sediment, such as mud.
Explanation:
<span>Firstly, producers get their energy energy from the sun through photosynthesis, creating or producing nutrients in the plant. A herbivore consumer can then eat it getting it's nutrients so, consumers rely on producers for their food but decomposers rely on a carnivore or omnivore (consumer) to eat some species of a consumer. The decomposer, lets say a earth worm eats and consumes the rest of the animal breaking it down to it's core nutrients. So I guess you could say decomposers rely on carnivores/omnivores to kill each other and herbivores, and herbivores/omnivores rely on producers for nutrients to eat</span>
