Recombinant DNA technology is possible because all organisms
O A. rely on ribosomes to assemble proteins
B. have some of the same genes
C. use the same codes for amino acids
D. replicate DNA before cell division

Answers

Recombinant DNA is possible because all organisms use the same codes for amino acids. Option C is the correct one.

The genetic codes

One of the fundamental characteristics of the genetic codes is that they are similar in all living organisms.

Each genetic code is translated into an amino acid. Thus, living organisms use the same codes for their amino acids in the proteins.

This makes inserting the genes of one organism into the genome of another (recombinant DNA) very easy.

The oak and the maple are two different species of trees that also belong to different genera. However, these oak and maples do share many characteristics. Based on their similarities, which levels of classification would they share?

Answers

Answer:

Maple and oak trees are both deciduous angiosperms, so the wood each produces is classified as a hardwood. However, the difference between maple and oak wood is significant, and it would be difficult to mistake one for the other. All species of oak display a distinctive well-defined grain pattern whereas the maple wood grain tends to be creamy white with little visible grain. The differences don't stop there, but to really appreciate them, it's important to realize that within the broad category defined by oak is a subset of species that differ significantly from each other. The same is true for maple

3. A. How is active

3. B. What are transport proteins?

3. C. Explain why transport proteins

transport.

Answers

Answer:

1. Water(solvent) molecules travel from A across the cell membrane / semi permeable membrane to B until the concentrations of A and B become equal.2. Active transport moves molecules and ions from lower concentration to higher concentration with the help of energy in the form of ATP. On the other hand, passive transport moves molecules and ions from a higher concentration to lower concentration without any energy.3. A transport protein is a protein that serves the function of moving other materials within an organism. 

4. Active transport is the movement of materials through a cell membrane using cell membrane using cellular energy. ... transport proteins requires energy to function because it needs energy then passive transport that requires no energy at all.

Lichens that colonize bare rock secrete acids that break down the rock and start the soil-production process. Also, as lichens die, they provide some organic matter that also contributes to soil. Mosses can then colonize the thin soil; as mosses die, the soil thickens more allowing other hardy species to colonize

FIRST PERSON TO ANSWER GETS BRANLYSEST After Hunter drank a glass of milk, sugar levels in his blood increased. This stimulated the hormone insulin to be released. Insulin helped the sugar move from his blood into cells, so his blood sugar levels decreased. Which statement explains what happened next? Positive feedback caused his pancreas to stop secreting insulin. Negative feedback caused his pancreas to stop secreting insulin. Negative feedback caused his pancreas to produce more insulin. Positive feedback caused his pancreas to produce more insulin.

Answers

Answer:

The correct answer B

When the body gets the glucose, the glucose in the blood increase then the hormone insulin is released so that the glucose from the blood can be transferred from blood into the cells of the body.

The release of hormone insulin is a positive feedback.

Once the glucose is transferred into the cells of the body then the negative feedback starts acting that stops the secretion of insulin from the pancreas.

What will happen next is that negative feedback would cause his pancreas to stop secreting insulin.

The maintenance of relatively constant internal body processes depends largely on negative feedback.

Negative feedback mechanisms ensure that setpoints are returned.

Hence, whatever causes setpoints to be breached is reversed or removed totally.

In this case, the continuous secretion of insulin will further lower the blood sugar level and causes the setpoint to be breached further. Thus, the actuator (insulin) has to be removed.
