Choose the correct order for the formation of a recombinant organism and the expresssion of the
desired product.
I’m stuck on this one any advice?
The order for rDNA is to identify a target gene, select a plasmid, use a restriction enzyme, gene insertion, use ligase, introduce the recombinant DNA and detect recombinant cells. rDNA involves genetic recombination.
Recombinant DNA (rDNA) technologies are used in molecular biology laboratories to create chimeric DNA molecules containing nucleotide sequences from different species.
Recombinant DNA techniques can be used to identify and sequence genes, as well as to discover gene function.
The sequential steps of rDNA technologies are as follow:
Identify a gene of interest.Select a DNA plasmid to be used.Use restriction enzymes to cleave the plasmid DNA.Introduce the gene of interest in the plasmid.Use ligase enzymes to join both nucleotide sequences.Introduce the recombinant DNA molecule into the host cell.Detect and replicate the cells containing the desired recombinant DNA molecule.Learn more in:

Deer are herbivores. What effects do you think a high deer population would have on Wesselman Woods?
Answer & Explanation:
Overly large population of any herbivore = them eating large amounts of any type of vegetation. Which means that for the woods there are less grasses/vegetation and it will end up causing other animals to starve therefor messing with the food chain.
Is that what you're lookin for? :)
A high deer population can have several negative effects on Wesselman Woods. These effects include a decrease in plant diversity, damage to trees, increased erosion, and a high risk of disease.
Decreased plant diversity: Deer are selective feeders, and they prefer to eat certain types of plants. This can lead to a decrease in plant diversity in the forest, as deer will eat the most palatable plants and leave the less palatable ones.
Damage to trees: Deer will browse on young trees, which can stunt their growth or even kill them. This can lead to a decrease in the number of mature trees in the forest, which can hurt the forest's overall health.
Increased erosion: Deer can trample on the ground, which can lead to increased erosion. This can damage the forest's soil and make it more difficult for plants to grow.
Increased risk of disease: Deer can carry diseases that can be transmitted to humans and other animals. A high deer population can increase the risk of these diseases spreading.
In addition to these direct effects, a high deer population can also have indirect effects on Wesselman Woods. For example, a decrease in plant diversity can lead to a decrease in the number of insects and other animals that depend on those plants. This can have a cascading effect on the entire ecosystem.
It is important to manage the deer population in Wesselman Woods to prevent these negative effects. This can be done through a variety of methods, such as hunting, fencing, and altering the forest's habitat.

What is the difference between diffusion and osmosis?
What makes a membrane semipermeable?
What characteristics of a molecule affect whether it can pass through the plasma membrane of a cell?
In the simulation, when protein molecules were evenly distributed on both sides of the membrane, was the solution isotonic, hypertonic, or hypotonic?
Which direction was water flowing?
In the simulation, when protein molecules were more highly concentrated on the inside of the cell than outside of the cell, was the solution isotonic, hypertonic, or hypotonic?
Which direction was water flowing?
Why is it important that the plasma membrane surrounding cells is semipermeable?
What would happen if it were not semipermeable?
1) Diffusion : Is the movement of molecules / ions from a region of higher to lower concentration. It may or may not occur across a semi permeable membrane.
In diffusion there is no challenge involved as it is along the concentration gradient, but in active transport movement of molecules occur against concentration gradient ie; from lower to higher concentration.
2) For active transport, energy is vital for movement, in this case protein molecules function as molecular pumps to enable the cell accumulate glucose/ions, against concentration gradient. Here metabolic energy ATP is required.
3)Facilitated diffusion is a type of passive transport in which ions/molecules cross the semi permeable membrane because permeases present in the membrane facilitate the transport.
Like simple diffusion facilitated diffusion doesn't require metabolic energy and simply occurs across the concentration gradient.
4) Osmosis : is movement of water from hypotonic solution (lower concentration) to hypertonic solution (higher concentration) through a semi permeable membrane.
The cell membrane being permeable to water allows to and from movement of water molecules along the concentration gradient.

Your answers may vary, but these sample answers are a model to follow.
Diffusion is the process of a substance moving from an area of high concentration to an area of lower concentration. Osmosis is a type of diffusion where water moves across a semipermeable membrane still from an area of high concentration of water to an area of lower concentration of water. This corresponds to water moving from an area with a low concentration of solute to an area with a higher concentration of solute.
A semipermeable membrane allows some substances to pass through it.
The plasma membrane of a cell allows small uncharged molecules to pass through it, but not large molecules and not charged ions.
The protein molecules were evenly distributed on both sides of the membrane, so this solution was isotonic.
In an isotonic solution, water moves both in and out of the cell, which was observed in the simulation.
The protein molecules were more highly concentrated on the inside of the cell, so this solution was hypotonic.
In hypotonic solutions, water moves into the cell to help dissolve the higher amount of solute inside the cell, which was observed in the simulation.
A semipermeable cell membrane is important to allow some molecules, like proteins, to be more highly concentrated inside the cell than outside the cell. If the cell membrane were permeable, the molecules on the inside of the cell would exit the cell and be evenly distributed in the cell and in its environment.
If the cell membrane were not permeable at all, the cell would not be able to receive nutrients from its environment.
Diffusion and osmosis has one difference which is the presence of semi-permeable membrane.
What is the difference between diffusion and osmosis?Diffusion is the movement of particles from an area of higher concentration to one of lower concentration while on the other hand, osmosis is the movement of particles from a semipermeable membrane.
Cell membrane is selectively permeable which only allows some molecules inside the cell because of its structure. So we can conclude that diffusion and osmosis has one difference which is the presence of semi-permeable membrane.
When protein molecules were evenly distributed on both sides of the membrane, the solution will be isotonic because of the same quantity on both sided. There is no movement of water in the body.
When protein molecules were more highly concentrated on the inside of the cell than outside of the cell, the solution will be hypotonic because of the less amount of water in the body.
