You splice DNA fragments from a "foreign" source into the patient's gene so that the gene will begin manufacturing the enzyme. The foreign DNA + the new DNA
Answer:
recombinant DNA
Explanation:
In molecular biology, recombinant DNA molecules are genetic sequences formed by combining DNA material from different sources (i.e., organisms, populations, species, etc). Proteins produced from DNA recombinant molecules are known as recombinant proteins. Molecular cloning is the most widely used technique in molecular biology in order to produce recombinant DNA molecules. In this technique, a cloning vector such as, for example, a plasmid of a bacterium, is used to insert a foreign DNA fragment into another cell which is then expressed in the host cell.

Normal cells responds to contact inhibition. When they come into contact with other cells, they stop moving and dividing. This keeps the cell contained within their own tissues. How did the mutated (cancer) cells show the evidence that they do not respond to contact inhibition?
Answer:
Cancer is basically a disease of uncontrolled cell division. Its development and progression are usually linked to a series of changes in the activity of cell cycle regulators. For example, inhibitors of the cell cycle keep cells from dividing when conditions aren’t right, so too little activity of these inhibitors can promote cancer. Similarly, positive regulators of cell division can lead to cancer if they are too active. In most cases, these changes in activity are due to mutations in the genes that encode cell cycle regulator proteins.
Explanation:
The mutated (cancer) cells show the evidence that they do not respond to contact inhibition because there is no stopping of division of the cells.
Normal cells VS mutant cellsNormal cells show response to contact inhibition when they come into contact with other cells, so they stop moving and dividing.
While on the other hand, The mutated (cancer) cells show the evidence that they do not respond to contact inhibition because there is no stopping of division of the cells so we can conclude that no stopping of division occurs which is the evidence that the cancer cells show no response to contact inhibition.

1. Would you consider a Zonkey (baby created from a donkey raised with a zebra) alive? Keep in mind that a Zonkey is sterile and cannot produce its own offspring.
2. Would you consider a virus alive? It requires a host completely to live.
Answer to 1:Yes the Zonkey is alive,not all organisms can reproduce. Some people are born with rare genetics were they can't give birth,so even if the Zonkey is sterile and can't produces it own offspring it is alive.
Answer to 2:Yes a virus is alive,it attacks the host and contains/kill other cells in your body. They also can multiple. If they can multiply and even attack and kill other cells they are alive.

Does Natural Selection affect individuals or populations? EXPLAIN.
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.
lee and Celia are lab partners. While Celia pours a chemical into a graduated cylinder, some of the chemical splashed onto her arm . What should happen next?
Answer:
Celia should tell the teacher and wash her hands and arms twice.
Explanation:
She should tell the teacher because if she is unsure of what to do, the teacher can help her. If there is no teacher present, she should wash her hands and arms twice to remove as much of the chemical as possible. Then she should call a poison help or chemical help center if she is unsure of what to do next.
What is the phase change from gas to liquid?
A. Sublimation
B. Condensation
C. Vaporization
D. Transpiration
Answer:
Condensation
Explanation:
Condensation is the phase change from gas to liquid. For example, water vapor condenses when you are taking a shower because wet spots show up on a mirror after taking a shower.
Answer:
Condensation
Explanation:
Sublimation is when a solid turns into a gas. Condensation is when water in the air collects to form droplets that gather on a surface/object. Vaporization is when a liquid forms into a gas. Transpiration is a thing in plants where water transfers throughout the plant.
why do atoms of the same element always have the same number of protons but sometimes have different mass number? What do you call these atoms?
Answer:
However, some helium atoms have more or less than two neutrons. Atoms with the same number of protons but different numbers of neutrons are called isotopes. Because the number of neutrons can vary for a given element, the mass numbers of different atoms of an element may also vary.

You added 20 g of NaCl to 100 g of water. What is the percent by mass of the solute?
Answer: We are given:
Mass of solvent (water) = 100 grams
Mass of solute (NaCl) = 20 grams
Mass of the Solution:
Mass of Solution = Mass of Solute + mass of Solvent
100 + 20 = 120 grams
Mass Percent of NaCl:
We know that
mass percent of NaCl = (Mass of NaCl / Mass of Solution) * 100
replacing the variables
Mass% of NaCl = (20 / 120)*100
Mass% of NaCl = 100 / 6
Mass% of NaCl = 16.67%

Which of the following is a requirement for a population to be in Hardy-Weinberg equilibrium?
A) The population must be very small
O
B) immigration must outpace emigration
O
C) each allele must be equally beneficial
O
D) There must be a high mutation rate
I think the answer is B. Immigration must outpace emigration. Hope this helps!
Hardy-Weinberg equilibrium is the principle of the genetic variation being constant. Each allele must be equally beneficial for a population to be in equilibrium. Thus, option C is correct.
What is the requirement of Hardy-Weinberg equilibrium?
Hardy-Weinberg equilibrium states the invariant nature of genetic variation when there are no disturbing factors in a population. For an equilibrium condition, the population should have a large size. Each allele must be equally beneficial so that there is no genetic drift.
There should be no immigration or emigration of the organism in a particular population as it affects the generation and individuals. Also, there must be no spontaneous mutations for the variation to occur.
Therefore, each allele must be equally beneficial for equilibrium.

(Uhm help?) The law of conservation of energy states that when there is an energy transfer or transformation, energy is lost.
Assuming this is a true/false question, the answer would be false.
According to the law of conservation of energy, energy is neither created nor destroyed; it simply changes forms.
Unless you are saying that some energy would be lost as heat, This is true.
Answer:
ae you trying to find the meaning?
Explanation:
The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it's added from the outside. The only way to use energy is to transform energy from one form to another.
ex: the cue ball is shot at a stationary 8 ball. The cue ball has energy. When the cue ball hits the 8 ball, the energy transfers from the cue ball to the 8 ball, sending the 8 ball into motion. The cue ball loses energy because the energy it had has been transferred to the 8 ball, so the cue ball slows down.

3. How does catastrophism explain how the fossil formed?
Answer:
Catastrophism, doctrine that explains the differences in fossil forms encountered in successive stratigraphic levels as being the product of repeated cataclysmic occurrences and repeated new creations. ... This doctrine generally is associated with the great French naturalist Baron Georges Cuvier
The mechanism of catastrophism directly explains the process of fossil formation. It described the natural history that has been punctuated by catastrophic events that altered the way life developed and rocks were deposited.
What is Catastrophism?Catastrophism may be defined as a type of geologic doctrine that significant changes in the earth's crust that have in the past been brought about suddenly by a series of events like mass extinction.
This catastrophic doctrine explains the differences in fossil forms encountered in successive stratigraphic levels as being the product of repeated cataclysmic occurrences and repeated new creations.
Therefore, the mechanism of catastrophism directly explains the process of fossil formation.

Developing a new vaccine takes about 5-10 years. So how is it possible to develope Corona vaccine so quickly?
Answer:
vaccines were designed by using new technologies (i.e., RNA-based vaccines and adenovirus-based vaccines)
Explanation:
RNA-based vaccines are vaccines based on the delivery of specific messenger RNA (mRNA) sequences that are capable of encoding only one viral protein, thereby preventing the complete viral cycle/replication. Subsequently, this protein is recognized by the immune system that generates memory immunity by synthesizing specific antibodies against this protein (in this case, the spike S protein). On the other hand, adenovirus-based vaccines are vaccines designed by inserting a transgene cassette into an adenovirus which is used as vector to produce one specific viral protein inside the host. Like mRNA vaccines, this antigenic viral protein is then recognized by the immune system in order to produce antibodies against a defined protein epitope, thereby producing memory immunity.

A)phototropism
B)dormancy
C)thigmotropism
D)gravitropism
A plant is placed near a window. Instead of growing straight up, the plant grows to the side. This plant demonstrates phototropism. Therefore, option A is correct.
What is phototropism?A plant can maximize photosynthetic light absorption in the aerial portion and water and nutrient uptake in the roots by using phototropism, or the differential cell elongation displayed by a plant organ in response to directed blue light.
Auxin is a hormone found at the ends of leaves and stems that reacts to light. It enables the plant to grow in a way that is favourable to the light source.
