Some antibiotics work by disrupting ATP production in bacteria. Which of the following will the bacteria lack when ATP production is disrupted?
A. genetic material for reproduction
B. energy to perform life processes
C. nucleic acids to make proteins
D. cytoplasm to diffuse oxygen
When there is a lack of bacteria at the time when ATP production is disrupted so here the energy is performed. Hence the option b is correct.
Reason of lacking bacteria:At the time when there is some kind of antibiotics work is done by disrupting ATP production in bacteria.
So the lacking of bacteria at the time when ATP production is disrupted so it is because of the energy to perform the life processes.
hence, the option b is correct.

(PLEASE HELP!!!) Suppose scientists genetically modified a species of algae to produce more oil. This algal species reproduces asexually. Will all of the offspring of the genetically-modified algae also produce more oil? How do you know?
Answer:
Yes all of the offspring of the genetically-modified algae would produce more oil.
Explanation:
When an organism is genetically-modified to reproduce asexually, it makes exact copies of itself since it is the only one passing genes whereas if normal sex were to occur and both parents would pass 50%-50% of their genes down to the child.

Answer:
Hemoglobin F has a different composition from the adult forms of hemoglobin, which allows it to bind (or attach to) oxygen more strongly. This way, the developing fetus is able to retrieve oxygen from the mother's bloodstream, which occurs through the placenta found in the mother's uterus.

Earth's core is the source of the energy that drives the movement of tectonic plates. Which two processes help transfer this energy outward to earth's crust?
Answer:The two processes are CONDUCTION and CONVECTION
Explanation:
The Energy produced in the Earth core is generated by Sun, gravitational force , radioactive decay, and the Earth' rotation, To maintain balance in the earth, The processes of CONDUCTION and CONVECTION transfer energy (HEAT) to Earth's interior, which also helps the movement of tectonic plates at a constant rate.
Now, inside the earth mantle is made up of hot solid rock and because Conduction occurs more in solids, Its currents helps the continuous transfer of heat energy from the warmer mantle at the bottom to the cooler mantle at the top While Convection currents in the core move thermal energy causing the rising and sinking of warm and cooler molten rock inside Earth, thereby maintaining the motion of tectonic plates and creating a balance in the earth.
Answer:
Conduction and Convection

As a result of the experiment scientists did with Mexican tetras, it seems likely that their first hypothesis about blindness in the tetras is right. Explain how the result of the experiment supports their first hypothesis.
The scientists' first hypothesis is that blindness gives the fish some sort of evolutionary advantage, but not directly.
The experiment was: The scientists transplanted a lens from the eye of a surface tetra embryo into the eye of a cave tetra embryo. The result was striking—the surface tetra lens into the cave tetra caused all of the surrounding tissues to develop into a healthy eye.
A result that supports the hypothesis 'blindness gives the fish some evolutionary advantage, but not directly' may be a higher fitness in close relatives of fish.
What is a hypothesis?An scientific hypothesis is a given explanation to a scientific observation from the real world.
A hypothesis must be verifiable, which means that it can be confirmed or rejected by using the scientific method.
In conclusion, a result that supports the hypothesis 'blindness gives the fish some evolutionary advantage, but not directly' may be a higher fitness in close relatives of fish.

Why are organisms in lower parts of the food chain not affected but organisms at the top of the food chain are?
Answer:
the organisms at the top of the food chain are effected because theyre bigger and the need more food and prey to survive. for example sharks, if fish arent thriving because they arent eating enough from the bottom of the food chain, the sharks cant eat them and the sharks will starve.
Explanation:
Answer:
The organisms at the bottom of the food chain have a tendency of reproducing faster. (unlike the top of the food chain). Don't think that the the organisms at the bottom of the food chain are not as important though! Everything is important in any food chain!
