Match the pathway with its most highly regulated enzyme.
Andrej [43]

Answer:

A.Glycogenesis: Glycogen synthase

B. Glucogenesis: Fructose 1,6 biphosphate phosphatase

C. Urea cycle  : Carbamoyl phosphate synthetase

D.Fatty acid synthesis:  Acetyl CoA carboxylase

E.Glycolysis : Phosphofructokinase 1

F. Pentose phosphate pathway: Glucose-6-phosphate dehydrogenase

Explanation:

A. Glycogen synthase converts glucose into glycogen during glycogenesis.

B. Fructose 1,6 biphosphate phosphatase catalyzes condensation of dihydroxyacetone phosphate (DHAP) and glyceraldehyde-3-phosphate during glucogenesis.

C. Carbamoyl phosphate synthetase I catalyses production of arbamoyl phosphate during urea cycle.

D. Carboxylase controls fatty acid metabolism.

E. The phosphofructokinase 1 is an important enzyme that regulate  formation of two-phosphate sugar molecules during glycolysis.

F. Glucose-6-phosphate dehydrogenase participates in the pentose phosphate pathway. This pathway gives reducing energy to cells.

A student does an experiment for a science fair to study whether temperature affects the timing of a cricket’s chirps. The stude
Galina-37 [17]

Answer:The timing of the cricket's depends on the temperature of the box

so the answer should be

timing of the cricket's chirps

Explanation:Hi!

There are a few types of variables in these types of experiments. They are independent, dependent, and controlled.

The independent is the one changed by the scientist, or in this case, the temperature. The controlled is the things that remain constant through every case, and the dependent is what is being observed, seeing if it changes through the altercation of the independent variable.

In this case, what is being observed is the timing of a cricket's chirps, because it is being watched whether or not temperature affects it.

Therefore, your answer is the third choice, or the timing of the cricket's chirps.

Hope this helped!

alukav5142 [94]

The intermediate disturbance hypothesis predicts that species diversity will be highest  when the frequency and/or intensity of disturbances are intermediate

Explanation:

The diversity of the species is maximised at an intermediate near of anthropogenic as well as natural disturbances. As the competitively inferior disturbances are being tolerated for species disturbance and are termed to be dominant. Co exist of the sensitive species when the disturbance are either frequent or rare, which possess the reduced level of the disturbances. the productivity is predicted as very less due to competitive exclusion. As the disturbances increases productivity becomes less as most of them unable to sustain the regular destructive occurrence. So with the intermediate disturbances productivity is high as the rapid colonizers and dominant competitors are able to coexist.

A large family has a history of multiple aneuploid diseases such as Down Syndrome, trisomy-18 and Klinefelter Syndrome (XXY). Th
SpyIntel [72]

Answer:

Genes coding for proteins involved in chiasma formation.

Explanation:

Chiasma is the connecting link between two non sister chromatids from homologous chromosomes. At chiasma chromosomal crossover takes place in which the genetic material is exchanged between the chromatids. During meiosis aneuploidy occurs if chiasma is absent or impaired due to a mutation in genes encoding for proteins involved in chiasma formation.

Aneuploidy is characterised by presence of abnormal number of chromosomes in cells. They can be 45 or 47 in number apart from the usual 46. Due to impaired chiasma, chromosome pair fails to separate and is passed on to the egg or sperm as it is hence there is one gamete with an extra chromosome and one gamete with a less chromosome. Aneuploidy can result in many genetic disorders like three copies of chromosome 21 can result in Down syndrome.

What is the amplitude and wavelength
zepelin [54]

Answer:

The amplitude of a wave is the height of a wave as measured from the highest point on the wave (peak or crest) to the lowest point on the wave (trough). Wavelength refers to the length of a wave from one peak to the next.
