G you extracted your dna from cheek cells. the concentration of your dna sample is 250 ng/μl. the dna template for pcr should be

10 ng/μl. you should mix _____ μl of your dna sample and _____ μl of water to make final volume of 100 μl of dna that has the concentration of 10 ng/μl.

You should mix 4µl of DNA sample and complete it with 96µl (100-4) of water.

You can figure this out by using  C1.V1 = C2.V2
C1 = 250 <span>ng/μl (Sample Concentration)
</span>V1 = ?          (the necessary volume to take from the DNA sample)
C2 = 10 <span>ng/μl (PCR concentration)
</span>V2 = 100 µl (total volume)

V1 = \frac{C2 . V2}{C1} = \frac{10 . 100}{250} = 4µl

For the water: 100µl (total volume) = 4µl + Water
Water volume = 96µl

Speculate as to how the information obtained from the sequencing of the human genome might be used to someday eliminate inborn e
Katena32 [7]

Answer:

Explanation:

Sequencing the human genome is the function of the human genome project with the goal of determining the base pairs/order of DNA nucleotides that make up human genome, and also identifying and mapping all of the genes of the human genome both from the physical level and its functions in molecular medicine. The benefits in this field could allow for better diagnosis of disease, early detection of certain diseases, and gene therapy and control systems for drugs.

Inborn errors of metabolism are rare genetic (inherited) disorders where the body cannot properly digest and turn food into energy through the normal pathway. The disorders are usually caused by mutations in specific enzymes that help in the break down of these foods.

Through the study of the human genome, sequences involved in these mutations giving rise to these disorders are identified and mapped to their variuos locations. This can help in the early diagnosis of the disorders and effective control system for drugs and gene therapy against these disorders.

Answer:

Arrows :

It shows how energy and nutrients are transferred from plants (producers) to herbivores and carnivores and through to decomposers. ... The arrows in the food chain below depict the direction in which energy and nutrients flow, i.e. the arrow always points from the eaten to the eater.

Greatest amount of energy transferred: Grass aka Autotrophs.

A sequence of living organisms which involves the transfer of food energy from producers, through a series of organisms with repeated eating and being eaten is called food chain. Each level or step in a food chain where the transfer of energy takes place is called trophic level. According to the pyramid of energy, the energy content is maximum in autotrophs or producers. Autotrophs are the plants which prepare their food by photosynthesis. They are the primary producers and primary source of food energy. The flow of energy is unidirectional from producer to consumer level. The energy decreases at each trophic level of the food chain, as part of the energy is lost as heat and major part of the energy is liberated during respiration for use in various activities. Only 10% of the energy of previous trophic level is received by next trophic level, as proposed by 10 percent law of Lindeman.
