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.

How does evolution result in reproductive success?
Answer:
Often when species evolve, they receive a trait that may make them live longer or make it where their survival chances are significantly increased. Which in turn can make their offspring stronger and able to live longer, therefore increasing their population.

A scientist was studying the stars and their influence on the personalities of 100 people over a Four year time period. Through his investigation, he determined that people that were born during August were more strong-willed and driven than individuals born in October. People born in October were more relaxed and could better handle stress. Is the scientist’s research considered science?
Yes, because the scientist conducted his research for an extended period of time.
Yes, because the scientist followed the scientific method.
No, because the scientist conducted his research with 100 people
No, because the scientist followed personalities which is pseudoscience.
Answer:
No, because the scientist followed personalities which is pseudoscience.

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.

A plant is placed near a window. Instead of growing straight up, the plant grows to the side. What is this plant demonstrating? (1 point)
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.

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.

WILL MARK BRAINLIEST!!!!Which of the following processes express the information encoded by DNA

A. Transcription and translation
O B. Asexual and sexual reproduction
C. Photosynthesis and respiration
D. Mitosis and meiosis
Answer:
C
Explanation:
Thats the tea
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.

(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.

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.
