Explain how the material changes form

Biology
2 answers:
ArbitrLikvidat [17]2 years ago
5 0

Explanation:

Heat makes many solids, especially metals, softer and easier to shape. As the temperature rises, most solids eventually melt to the liquid state. ... Heat can trigger chemical reactions between mixtures. In an oven, heat changes a cake mix from a sticky liquid into a fluffy solid.

The condition Marfan syndrome results from the production of abnormal elastin, the main protein component of elastic fibers. Pre
Marina86 [1]

Answer:

Elastic fibers are made of elastin and microfibrils, that are elastic protein structures. The proteins can be stretched and resume normal shape. These fibers are found in parts of the body such as arteries, skin, lungs, connective tissue and heart that require some stretching. Marfan syndrome affects the elastic connective tissues causing symptoms like dilation of the aorta that doesn't resume normal lumen diameter (aortic aneurysm), and curving of the spine (scoliosis).

The lungs are unable to stretch and resume shape normally and this affects the respiratory system. The subjects will suffer from shortness of breath, wheezing and chest pain.

The sheath/endoneurium of neurons is connective tissue. This part of a neuron allows signals to travel effeciently along the axon of the neuron. This means that a person with Mafran syndrome has a slower response to stimuli that ordinary persons.

Answer:

The smallest size tube that will hold the entire reaction is 0.5ml

Explanation:

25ul (DNA sample) + 25ul (enzyme) + 50ul (buffer) + 400ul (water) = 500ul total

since 1000ul=1ml, then 500ul = 0.5ml

Answer:

The device that mostlikely would not be used P20

Explanation:

P20 is a pipette used to measure and sample volumes of 20ul maximum.

Answer:

The reaction mix will have 400 units of the enzyme.

The working dilution will be 0.8 Units/ul.

Explanation:

The mix has 20ul of the enzyme which is 20Units/ul. Then we have 20ulx20Units/ul= 400 Units of enzyme in the mix.

Since the final volume is 500ul, the final concentration 400Units/500ul=0.8 Units/ul.
