Assume that in cattle a spotted coat is dominant to an even coat, short horns are dominant to long horns, and the traits for coa
kow [346]

Answer:

C. 1/4

Explanation:

Let's assume that the allele for the spotted coat is "S" and the one for the even coat is "s". The allele "L" gives short horns while the recessive allele "l" imparts long horns. The genotype of the cattle heterozygous for both traits would be SsLl. A cross between two heterozygous cattle would produce progeny in following phenotype ratio=

9 spotted coat and short horns: 3 even coat and short horns: 3 spotted coat and long horns: 1 even coat and long horns.

Therefore, the proportion of the progeny with long horns = 4/16= 1/4

Atropine is sometimes used to dilate the pupil for an eye examination. which receptor would atropine block?
grigory [225]

Atropine would block the receptor called muscarinic acetylcholine receptors present in the eye.

Atropine is the Anticholinergic agent which is also known as parasympatholytics. The activity of neurotransmitters at the receptors leads to pupil constriction.

Atropine is used to block these receptors that allow the pupillary muscles to relax. This causes the dilation of the pupil.

Atropine is the mydriatics that is used for pupillary dilation to conduct a detailed examination of eye diseases.

without this medication, the pupil will only dilate in the darkness. However, doctors cannot examine the eye problems as there is darkness as they need light for checkups.

boyakko [2]

Answer:

The correct option is A

Explanation:

To determine if water temperature has an effect on weathering of sedimentary rocks, different number (perhaps three) of identical sedimentary rocks should be obtained and then individually placed in different water temperatures (with at least one of the "water volumes" used for each having a temperature close to the room temperature so as to be used as the control).

Thus, each of the identical sedimentary rock can be broken into three and placed individually; as in one part of the rock in 20 °C of water (control), another part of the rock in 40 °C and another in 60 °C of water.

This above procedure should be repeated for the remaining two other identical sedimentary rock to confirm if there is any effect.
