Answer:
DNA molecules have negative charges, and so when placed in an electric field they migrate toward the positive pole.
Explanation:
Electrophoresis is a technique that <u>uses differences in electrical charge to separate the molecules in a mixture</u>. DNA molecules have negative charges, and so when placed in an electric field they migrate toward the positive pole. The rate of migration of a molecule depends on two factors, its shape, and its charge-to-mass ratio.
A gel, which is usually made of agarose, polyacrylamide, or a mixture of the two comprises a complex network of pores, through which the DNA molecules must travel to reach the positive electrode. The smaller the DNA molecule, the faster it can migrate through the gel. Gel electrophoresis, therefore, <u>separates DNA molecules according to their size.</u>
<span>There are diagnostic analysis used to
identify patients with heart failure. One of which is echocardiogram and chest
x-ray that rely on imaging of the heart to assess its structure and function. Another
ancillary test to detect abnormalities that may point to heart failure is the B
type Natriuretic peptide, the detection of this serum levels is known to rise
in the heart failure syndrome.</span>
Answer:
ECOLOGICAL FOOTPRINT
you would need about 41.6 earths all together
Explanation:
just add them up.
Answer: It can decrease or increase a population of species.
Explanation: Limiting factors include the availability of food, water, shelter, and etc. When a population of species are limited in any of these, they either move or adapt to their environment. So, population tends to decrease. The population that may finds an abundance of resources will find that their numbers tend to increase. This cycle is repeated over and over again.
Hope this helps!!!
