All of the following are effector responses that increase body temperature, EXCEPT A : vasodilation of dermal blood vessels B :
Ainat [17]

Answer: Option A

Explanation:

The effector response that increases the body is not associated with vasodilation of dermal blood vessels.

The skins's immense blood supply helps in temperature regulation of the body. The dilated blood vessels helps in heat loss and lowers the body temperature.

Unlike, them the vasoconstriction retains heat and increases the body temperature.

So, the correct answer is option A

How does hydropower and solar power work together?
KIM [24]

Solar energy is energy that comes from the sun and is captured by solar cells. These cells transform the energy of photons of light into electrical energy. One mechanism is the energization of electrons, here the energy of the photons is transferred to the electrons, which can already be considered electric energy.

As for the hydroelectric energy, here the waterfalls or rivers flow driving a turbine, which will transform the movement into usable electric energy as it rotates.

if a scientist wanted to compare the expression of one gene under two sets of conditions, what technique would they use?
timurjin [86]

If a scientist wanted to compare the expression of one gene under two sets of conditions, chain termination is the technique they would use.

Chain termination is any chemical response that ceases the formation of reactive intermediates in a sequence propagation step withinside the route of a polymerization, efficaciously bringing it to a halt.

Sanger sequencing, additionally referred to as the “chain termination technique”, is a way for figuring out the nucleotide collection of DNA. The approach become evolved with the aid of using time Nobel Laureate Frederick Sanger and his colleagues in 1977, subsequently the call the Sanger Sequence.

How are cancer therapies tailored to nucleotide synthesis -explain using the example of fluorouracil and methotrexate.
nika2105 [10]

Answer:

By preventing the synthesis of DNA halting cell growth.

Explanation:

Fluorouracil and methotraxate prevent the synthesis of the neucleoside Thymidine thus preventing DNA replication and elongation. Methotraxate has a structure analogous to Folic acid which is important for thymidine synthesis. Thus, it acts as a competitive inhibitor on dihdrofolate reductase an enzyme that is essential for tetrahydrofolate formation, a folic acid derivative.

Fluorouracil acts by inhibiting thymidylate synthase which catalyses an essential step in Thymidine synthesis.
