What is the best choice for a blank when calibrating the spectrophotometer when you will later measure the absorbance of beverag
ELEN [110]

When calibrating a spectrophotometer, measuring absorbance concurrently is the best option for a blank since it is proportional to the concentration.

Beer's law states that A = a b c, wherein there is the diffusion coefficient at a constant, b is the actual route length, & c is the concentration. Direct proportionality exists between b and c and absorbance.

Once the route length is doubled, incident light contacts double as many molecules in the solution. The consequence is a doubling of absorbance, which is equivalent to a doubling of molecule concentration.

There are two ways to detect chemicals using spectrum scanning. One approach involves turning the monochromator continuously with a stepping motor while gradually altering the wavelength connected to the output slit.

It is more practical to use diode array detectors. Up to a few hundred photodiodes may be incorporated into the chip that makes up this device.

What are the advantages and limitations to using fossils to study the living things that lived in the past?​
ollegr [7]

~Hello

Fossils are one of the best evidence of evolution, mainly because they are the remains of living organisms from the past, which allow us to compare them with living organisms. However, the fossil record is notoriously incomplete and it is also biased in favor of animals with hard body parts, such as skeletons and shells. Soft bodied organisms and soft body parts are rarely preserved and there are often huge gaps in some evolutionary sequences. For example, Archaeopteryx is the earliest known bird, but it is already a bird, nothwithstanding some of the features that are unquestionably reptilian. The earliest known reptile with feathers is Longisquama, but there is a gap of some 75 million years between Longisquama and Archaeopteryx, and nothing has yet been found that are intermediate between these two important fossils.

Finally, DNA is virtually unobtainable from fossils, making it nearly impossible to compare the DNA of most fossils with living organisms. In terms of phylogenetic tree construction, DNA data is far superior to fossil evidence. However, if not for the existence of fossils, DNA data alone would be unconvincing as evidence of evolutionary change.

ASAP PLS There are lots of big words in genetics! One way to start thinking about the process of meiosis is to ask yourself some
mihalych1998 [28]

Answer:

1) the genes and chromosomes do not double after each generations because parental sex cells are haploid and only contain one set of chromosomes. During fertilization the two cells fuse to form a diploid zygote with two copies of genes and chromosomes. For example a normal human has 46 chromosomes (2 copies of 23 chromosomes) during reproduction gametes which contain 23 chromosomes (haploid) fuse to form an offspring with the correct number of chromosomes ( 23 + 23 = 46).

2) offspring only receive one set of chromosomes from each parent so to maintain the chromosome number of humans. If this did not happen you would not be the same species.

Are catabolic pathways endergonic or exergonic reactions? Compare the amount of free energy in the reactants to the amount of fr
atroni [7]

Answer:

Catabolic reactions are exergonic.

Explanation:

Exothermic reactions are catabolic, that is, they catalyze molecules, disintegrate them to be able to release energy to the environment that surrounds them and that is how they release or yield to the environment.
