Answer:
The correct answer is a. Seminal vesicle
Explanation:
Seminal vesicles are the pair of glands that are found in the male pelvic region below the urinary bladder. Seminal vesicles produce about 60% of fluid present in the total semen ejaculate therefore without seminal secretion semen would be very low in volume.
The seminal fluid contains nutrients like fructose that provide energy to the sperms, phosphorus and potassium that helps in the motility of sperms. Seminal fluid is alkaline in nature which protects sperms from the acidic environment in the vagina. Therefore the correct answer is a. Seminal vesicle.
Answer:
Enzymes are proteins that are able to lower the activation energy for various biochemical reactions. ... Enzyme catalysis. An enzyme catalyzes a biochemical reaction by binding a substrate at the active site. After the reaction has proceeded, the products are released
Hope this helps!!
1) all the possible genotypes are also identified by color in the image below :AABBAAbB or AABbaABB or AaBBaAbB or aABb or AabB or AaBbAAbb
aAbb or AabbaaBB
aabB or aaBbaabbThere are 9 different genotypes in total. These can be achived by mixing the alleles of both genes of each parent (just like it's represented in the square).
2) there are 4 phenotypes
-one with an allele A and allele B that would dominate the other. (AABB, aAbB, for example)
- one with all alleles recessive- aabb
-one with the recessive alleles in the gene A but heterozygotic/homozigotic dominant for gene B ( for example: aaBB)
-one with the recessive alleles in the gene B but heterozygotic/homozigotic dominant for gene A ( for example: Aabb)
3) <span>probability of having offspring with the aabb genotype: 1/16
Just by looking at the punnet square, you can see that only one has the aabb genotype, in all the 16 possibilities.

Explanation:
Increases in temperature increase molecular activity, and can result in a higher rate of collisions between enzymes and substrates. If the temperature rises too high, however, the enzymes could become denatured, and the positive effects of the temperature increase could be nullified.
They are located in cochlea.
