If animal cells are placed in hypotonic, hypertonic, and isotonic concentrations, then:
Hypotonic → experience hemolysis or ruptureHypertonic → experience crenation or shrinkage.Isotonic → will remain normal and stable.What happens if animal and plant cells are placed in hypertonic and hypotonic solutions:
In a hypertonic solution (high solution concentration)
Animal cells will experience crenation or shrink because the concentration outside the cell is high.Plant cells will undergo plasmolysis due to the detachment of the membrane from the cell wall.In a hypotonic solution (low solute concentration)
Animal cells will undergo lysis or rupture because water enters the cell which causes the cell volume to increase.Plant cells will experience turgid or swelling because these cells have a cell wall that can maintain their condition.Learn more about hypertonic and hypotonic solutions https://brainly.com/question/4237735

some species of insect are thermogenic and capable of producing their own heat using the same organelle that we use. if a physiologist wanted to study the mechanism of heat production, what cellular component should she focus on?
The cellular organelle that should be focused while studying about the mechanism of heat production is: mitochondria.
Cell organelles are the sub-cellular components of the cell that work in order to make the cell alive and functional. There are various cell organelles like nucleus, mitochondria, ribosomes, chloroplast, Golgi body, etc.
Mitochondria is the cell organelle involved in the formation of ATP for the life processes to be performed. Thus, mitochondria is actively involved with energy transduction and therefore contributes the maximum in heat production. Mitochondria is a double membranous cell organelle where ATP is produced in the inner mitochondrial membrane.

sediments along the coast are moved in and out of littoral cells (as part of a sediment budget) primarily by
Littoral cells are the areas of the coastline where sediment is constantly being moved in and out. This is usually done by waves and currents. The main reason for this is to keep the coastline from eroding away.
The movement of sediment along the coast is primarily controlled by the processes of erosion and deposition. Erosion is the process by which wave action and other agents break down and wear away rocks and other materials. This process typically occurs along the shoreline, where waves crash against the land.
Deposition is the process by which eroded materials are transported and deposited elsewhere. This can occur either offshore, where materials are carried by currents and then deposited on the seafloor, or onshore, where materials are transported by currents and then deposited along the shoreline.
The movement of sediment in and out of littoral cells is an important part of the sediment budget. The sediment budget is the balance between the amount of sediment that is being eroded and the amount that is being deposited. Littoral cells are areas of the coast where sediment is constantly being moved in and out. These areas are usually located near river mouths or along the shoreline.

A depolarization is when the inside of a neuron becomes _______________ the resting membrane potential.
When the resting membrane potential becomes less negative (more positive), that is called depolarization.
What is depolarization?
Depolarization is also known as hypopolarization, also called rising phase. Depolarization is nothing but loss of polarization. More specifically, it is the loss of differences in charge inbetween the inside and outside of a muscle or nerve cells’ plasma membrane. This occurs due to changes in permeability and also migration of Na+ ions to the interior.
The gated sodium (Na+) ion channels present on the neuron's membrane open up suddenly and allow sodium ions (Na+) present outside the membrane in order to rush inside the cell. The internal charge of the nerve changes from -70 mV to -55 mV as the sodium (Na+) ions quickly enter the cell.
So therefore, depolarization is nothing but resting membrane potential becoming less negative (more positive)

how the structure of dna determines the structure of proteins which carry out the essential functions of life through systems of specialized cells.
The structure of DNA determines the structure of proteins because proteins are made by the central dogma process where DNA is the initial component.
In the process of the central dogma, transcription is the process through which the DNA is transcribed into the mRNA. Through the information in the mRNA, proteins are produced by the translation process.
Hence, the structure of proteins as well its function etc are all determined by the DNA whose information is transcribed and translated for the formation of that particular protein.

The rate of transcription for a gene is found to be affected by a mutation. Where would you expect the mutation to appear on the dna?.
If the rate of transcription is affected by the mutation, the mutation is found in the exons region of the template DNA strand. This is the reason why transcription rates are affected.
How is the transcription affected?The transcription is a process by which the mRNA is formed from the DNA, and the mature mRNA consists of exons from the gene. These exons can form polypeptide chains during the protein synthesis process.
If the mutation happens in the promoter region of the mRNA or inside any sequence of mRNA, then it slows down the process, and as a result, the rate of transcription is slowed. The mutation changes the structure of the mRNA; as a result, the RNA polymerase can't cross it and carry out transcription at the slow rate.
Hence, the exons region of the gene that is present in the DNA should be mutated in order to slow the rate of transcription.

Plants have the capacity to respond to light, phototropism, and gravity, gravitropism.
Response of plants to the environmentPlants have the capacity to respond to their environment just like every other living organism. They respond to light, gravity, touch, water, and so on.
The response of plants to light is called phototropism. Responses can be positive or negative. Most plant's shoots are positively phototrophic while their roots are mostly negatively phototrophic.
In other words, the shoots of plants will always move toward light sources while their roots always tend to move away from sources of light. This fact has been demonstrated in several experiments.
The response of plants to the force of gravity is known as gravitropism. This response, just like response to light, can be positive or negative. The force of gravity acts vertically downward. As a rule of thumb, plants root respond positively to gravity while their shoots are always negatively gravitrophic.
