Which valves produce the second heart sound when they snap shut?
Taya2010 [7]
Answer: D) Pulmonary and aortic valves.

Explanation
There are two main heartbeats from a healthy heart.

The first beat is called the S1 or the lub, and it occurs when the atrioventricular valves (comprising the mitral and tricuspid valves) close.

The second beat is called the S2 or the dub, and it occurs when the semilunar valves (comprising the aortic and pulmonary valves) close.

Listening for heart beats is an essential part of cardiac auscultation.

N pea plants there is complete dominance for the trait of flower color. the p allele produces purple flowers and p produces whit
Reptile [31]
PP-  purple homozygote
pp- white homozygote
Pp- purple hetrozygote

If these flowers cross, we obtain heterozygote offsprings with a genotype: Pp (100% of them will be like this)

Now, if those offsprings cross with each other: Pp x Pp
results:
  1/4 would be purple  homozygote -> PP
  1/4 would be white -> pp
  2/4 would be purple heterozygotes -> Pp
Genotipic ratio: 3:1 (3 are purple; 1 is white)

Which one of the following hormones stimulates stem elongation and pollen tube growth? A. auxin (IAA. B. ethylene C. gibberellin
Lubov Fominskaja [6]

Hormones stimulates stem elongation and pollen tube growth gibberellins.

A type of plant and fungus hormone is gibberellin. Although its function in the development of fungi is not fully understood, extensive research has been done on it in plants. The other four major groups of plant hormones are auxins, cytokinins, ethylene, and abscisic acid. Gibberellin is one of these hormones. Gibberellin can make seeds come out of dormancy, lengthen cells, promote division, and even play hormonal and signaling roles in the fruiting and senescence processes. Numerous areas of the plant produce different types of gibberellin molecules. There are currently more than 100 distinct gibberellin molecules.
