Eukuaryotic cells are different from prokaryotic cells because eukaryotic cells
Eukaryotic cells contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts, the cell wall, and the structure of chromosomal DNA.

Practically speaking, how would you determine that Na + influx into a cell underlies the early current? Group of answer choices Remove Na + from the extracellular compartment and assess the early current under new conditions. Use the voltage clamp method to measure the current. Remove K + from the intracellular compartment and assess the early current under the new conditions. Treat the cell with tetraethylammonium. Replace intracellular Na + with its radioactive form and trace its movement across the membrane.
Answer:
Remove Na + from the extracellular compartment and assess the early current under new conditions
Explanation:
Na+ is a critical ion that influences the action potential in nerve cells. During the transmission of an impulse, the cell membrane is open so ions can flow through it, i.e., positively charged ions such as sodium ions (Na +) move within the cell, while negatively charged ions move outside the cell. This process produces a change in the action potential by rapidly increasing the positive charge in the nerve fiber, being thus the impulse propagated when this charge reaches +40 mv. In consequence, the effects of Na + on the single-channel current can be analyzed by removing positive ions and determining the change in the reversal potential of this channel.

Compare mitotic and post-mitotic cells (define, give example of each).
Answer:
Mitosis is a process where a single cell divides into two identical daughter cell.

Whilst bushwalking, Brian begins to feel chafing sensation in his thighs. In order to perceive this chafing, neural impulses must travel in one direction – from his (skeletal muscle, skin, brain, spinal cord) to his (brain, skin, spinal cord, skeletal muscle) This information would travel via (GVE,GVA,GSA,GSE) neurones.
WHICH ONE OF THE OPTIONS IN THE BRACKET
Answer: Skin; Brain, GSA - General Somatic Afferent
Explanation:
Whilst bushwalking, Brian begins to feel chafing sensation in his thighs. In order to perceive this chafing, neural impulses must travel in one direction – from his skin to his brain. This information would travel via GSA neurones.
The peripheral mechanoreceptors which are found on the skin and used to detect movement will detect the chafing and send it to the brain.
This information will be received by the brain through General Somatic Afferent neurons which are spread across the body and have the primary function of detecting touch and temperature.
What kind of display would be the best way to represent the data below? Type of species Critically endangered (%) Endangered or vulnerable (%) Plants 13 70 Invertebrates 0 35 Freshwater fish 9 37 Amphibians 7 30 Reptiles 5 28 Birds 0 12 Mammals 2 21 bar graph pie chart line graph scatter plot
Answer:
The table to this question is unclear, the detailed tabular form of this data has been attached.
The answer is BAR GRAPH
Explanation:
Bar graph or chart is one of the means statistical data is represented or displayed. A bar graph uses bars positioned horizontally or vertically to represent data. A bar chart is used to show comparison between the values of different categories. The length of each bar shows the degree of the measured data.
According to the data provided in the question, a comparison between the critically endangered species and endangered or vulnerable species in % of different types of species is described. Using a BAR GRAPH, the x-axis of the graph will contain the different types of species while the y-axis will contain the quantity in percentage (%) of the endangered or critically endangered species.
Note that, two different bars of different colors will be used to represent whether the species is endangered or critically endangered.

The food web shows the flow of energy through a sagebrush-steppe ecosystem.
Which of these organisms are in a trophic level that receives a larger percentage of the energy captured by the producers than the percentage received at the bats’ trophic level?
Mountain lions
Ground squirrels
Snakes
Hawks
Answer:
D. Ground squirrels
Explanation:
Took the test
Ground squirrels are at a trophic level that receives a larger percentage of the energy they consume as producers than the percentage received at the trophic level of bats. So, the correct option is B.
What is Trophic level?The trophic level of an organism is defined as the position it occupies in a food web where a food chain is a succession of organisms that eat other organisms and are themselves eaten. An organism's trophic level is the number of steps from the beginning of the chain.
Organisms at the lower trophic level have the highest percentage of energy compared to those at the higher trophic level that have the lowest percentage of energy. For the example above, if a ground squirrel has 100% energy, the next trophic level will receive 10% of the total energy from a lower trophic level that only has 10%, other higher trophic levels only receive 1%, then the next level Only 0.1%
Therefore, the correct option is B.

How does gel electrophoresis work? Group of answer choices DNA is negatively charged. When an electrical current is passed through a gel, the DNA is repelled by the nearby negative current and pushed across the gel towards the positively charged side. DNA is positively charged. When an electrical current is passed through a gel, the DNA is repelled by the nearby negative current and pushed across the gel towards the positively charged side. DNA is negatively charged. When an electrical current is passed through a gel, the DNA is repelled by the nearby positive current and pushed across the gel towards the negatively charged side. DNA has no charge. When a current is passed through a gel, the DNA is repelled by the negative current and pushed across the gel towards the positively charged side.
Answer:
DNA is negatively charged. When an electrical current is passed through a gel, the DNA is repelled by the nearby negative current and pushed across the gel towards the positively charged side.
Explanation:
Electrophoresis has become a standard molecular biology technique. This technique is based on the use of a constant-uniform electric field that enables the separation and identification of DNA fragments with different lengths, which form bands in the electrophoresis gel. Electrophoresis can be used to analyze not only DNA, but also RNA and proteins. During electrophoresis, the fragments of DNA that are negatively charged will migrate towards the positively charged electrode, where the duration of this movement will depend on the size of the DNA fragment, as well as of the pore size in the gel.
How did Louis Pasteur help disprove spontaneous generation?

Compound IB. Compound IIC. Compound IIID. Compound IVE. Compound
Answer:
C. Compound III
Explanation:
A metabolic pathway can be defined as a series of linked (successive) chemical reactions that are produced within the cell. In an enzymatic reaction, the reactants, intermediates, and products are referred to as 'metabolites'. These enzymatic products generally act as substrates for the successive chemical reactions. The metabolic pathways can be classified into anabolic (require energy to synthesize molecules) and catabolic (release energy) pathways.
