Non-steroidal anti-inflammatory drugs (NSAIDS) block the actions of the COX enzymes and their production of eicosanoids from ___
iVinArrow [24]

Answer:

Arachidonic acids

Explanation:

Non-steroidal anti-inflammatory drugs (NSAIDs) are drugs used due to their analgesic, anti-inflammatory effects.

It inhibit cyclooxygenase (COX) enzyme that takes part in the biosynthesis of prostaglandins (PGs) and thromboxane (TX) and the production of eicosanoids.

Eicosanoids are made by the enzymatic or non-enzymatic oxidation of arachidonic acid or from other polyunsaturated fatty acids (PUFAs) that are close to arachidonic acid which are 20 carbon units in length.

They are important cell signaling molecules that inhibit inflammation, allergy, fever,regulate abortion of pregnancy and normal childbirth, regulating cell growth.

Blue flower is dominant to yellow flower. Tall plant is dominant to short. Cross BbTt * BbTt. What precenetage of the offsprings
shtirl [24]

Answer:

The correct answer would be - 25%.

Explanation:

It is given that the Blue flower is dominant over the yellow flower which means Blue is represented by allele B here and allele b for yellow and Bb is a heterozygous case with a blue phenotypic character. Similarly, the Tall plant is dominant over short and represented by T and t respectively.

BbTt is a heterozygous condition and a cross with itself will produce :

Gametes: BT Bt bT and bt

          BT       Bt       bT       bt

BT     BBTT   BBTt   BbTT   BbTt

Bt      BBTt    BBtt    BbTt   Bbtt

bT     BbTT   BbTt    bbTT   bbTt

bt      BbTt     Bbtt    bbTt     bbtt

Here 4 out of 16 offspring are heterozygous for both traits represented by bold alphabets. Therefore the correct answer is 25%

Heterozygote advantage refers to the tendency for heterozygous individuals to have better fitness than homozygous individuals. T
ddd [48]

Answer:

False

Explanation:

Genetic variation is the difference in the sequence of DNA in the individuals of a population and a heterozygote has more genetic variation that homozygote person because heterozygote has two different alleles of a gene while homozygous individual have two same alleles.

Heterozygotes have advantage over homozygotes because it protects the individual from many genetical diseases and increase the genetic variation by increasing the gene pool in the population. So higher fitness results in more genetic variation in the population therefore the statement is false.
