Electric fish is a part of the group of animals which are responsible for producing charge. These organisms pump positively charged sodium ions from inside themselves to the outside environment.
What is electric fish?
An electric fish is an fish that can generate electric fields and transfer current through themselves. Most of the electric fishes are electroreceptive, which means that these fishes can sense the electric fields present in the environment. The only exception here is the stargazer family which is not electroreceptive.
The examples of electric fish includes Electric eel, that belongs to the genus Electrophorus, South American knifefishes responsible for the production of powerful electric shocks to stun prey.
If the electric fishes are supplied with the negative charge always then they will pump positive charge to neutralize the effect of that charge.

Water that falls onto land surfaces is either soaked into the ground or flows downhill into a body of water. The water that soaks into the ground is called groundwater.
Soil and rock that allow this water to pass through them are called ________.
A. aquifers
B. compacted
C. permeable
D. runoff
The capacity of a rock or other substance to let the passage of water is known as permeability, hence option c is correct.
What is groundwater?Groundwater may readily flow through permeable materials because the pore space is linked throughout the rock or sediment. Mud and clay are examples of materials with great porosity yet very limited permeability.
An aquifer is a water-bearing rock that easily transfers water to wells and springs, the aquifers may be dug into and water pumped out.
Therefore, water that falls onto land surfaces flows into water bodies or it may be soaked in the ground, this water flows through the soil and rock which are permeable, hence option c is correct.

Summarize cell division in prokaryotes
According to the research, the correct answer is that unicellular living beings like prokaryotes have their cell division by binary fission, forming two identical individuals (daughter cells).
What is binary fission?It refers to the process of cell division where first the deoxyribonucleic acid (DNA) is duplicated and then cytonesis occurs, which involves the separation of the cytoplasm.
In this sense, it gives rise to two daughter cells with identical genetic material, this is the reproduction method shared by certain yeasts, algae, bacteria and other prokaryotic organisms.
Therefore, we can conclude that the cell division mechanism of prokaryotes is through binary fission where two daughter cells arise.

Answer:
Yes and no
Explanation:
Natural Selection is the process of organisms adapting to the environment around them so yes individuals are effected through them adapting to the changes and they later pass their good traits to their offspring, and eventually the individuals who don't adapt die off, but the natural selection as a whole is just the process.

Joe is experimenting to determine which liquid will cause bean plants to grow faster. He watered the plants with equal amounts of liquid and measured their height every other day. The plants are in the same pots with different soils and placed in the same location. Will Joe be able to obtain reliable data to write a supported conclusion?
Yes, because he is only observing the height of the plant.
Yes, because he is consistent with watering the plants.
No, because he used different soils.
No, because he uses only one type of plant.
Answer:
No, because he used different soils.
Explanation:
which liquid will cause bean plants to grow faster.
He watered the plants with equal amounts of liquid and measured their height every other day.
The plants are in the same pots with different soils and placed in the same location.
Ok so last statement made the experiment wrong.
As a constant variable the soil should be the same for all plants only the liquid should change

Answer:

Explanation:

Hope this helps ;)
The process that expresses the information encoded by DNA and RNA is Transcription and translation, so option A is correct. Transcription is the process by which the genetic information stored in DNA is transcribed into RNA.
Transcription is the process by which the genetic information stored in DNA is transcribed into RNA. It involves the synthesis of an RNA molecule using one strand of DNA as a template. The resulting RNA molecule, known as messenger RNA (mRNA), carries the genetic information from the DNA to the site of protein synthesis. Translation, on the other hand, is the process by which the information encoded in mRNA is used to synthesize a specific protein. It takes place in ribosomes, where transfer RNA (tRNA) molecules interpret the genetic code on the mRNA and bring the corresponding amino acids to assemble the protein chain.
