Answer:
b
Explanation:
Genetic Organization of Prokaryotes Aids Fast Generation Times. Compared to eukaryotes, prokaryotes usually have much smaller genomes. On average, a eukaryotic cell has 1000 times more DNA than a prokaryote. This means that less DNA must be replicated (copied) with each cell division in prokaryotes
Answer:
Experiment 4. Relaxed, the drug will stop the calcium so that it does not act on the troponin
Experiment 5. Contraction: In order for the muscle to relax, the actin and tropomyosin union must occur.
Experiment 6. Relaxation: the release of the actin-myosin complex occurs with consumption of ATP, thus it slides and generates contraction, by adding a hydrolyzable analog, this reaction is avoided giving rise to a prolonged actin-myosin binding which leads to relaxation while last effect.
Experiment 7. Ca2 + Contraction is very necessary so that during muscle contraction troponin can be extracted.
Biotic factors of an ecosystem are all the living organisms that affect other organisms in an ecosystem and include animals, plants, microorganisms, dead organisms, and even animal waste. Example of biotic factors include: Grass as producers (autotrophs).
Answer:
Category D
Explanation:
In the USA, the Federal Animal Welfare Regulations require that research laboratories report animal use according to the species as well as the number of individuals subject to experimentation procedures. Moreover, animal use for research/teaching purposes is also reported according to the classification by pain and distress categories. Basically, this classification has four categories (B,C, D and E) in increasing order according to the pain level suffered by research animals. Animals within Category D include those subjected to potentially painful or stressful procedures. In consequence, in this category, it is imperative the utilization of proper anesthetics and/or analgesics in order to diminish the pain and suffering of these animals at the lower level possible.
Answer:
They are located in the same region
They all border the state of Kentucky
They are Virginia's westernmost watersheds
Explanation:
Big Sandy, Clinch-Powell and Holston watersheds are all located in Virginia.
These watersheds are located in the west region of Virginia alongside the border with the state of Kentucky
They are located next to each other and all tree connect with Kentucky.
With their area they are not the smallest nor the largest watersheds in Virginia.
Big Sandy's area is 990 sq miles, Clinch-Powell's is 1.811 sq miles, while Holston watershed's area is 1322 sq.miles
