Answer:

The correct answer is option A. diploid zygote and a triploid endosperm.

Explanation:

Double fertilization is a type of fertilization that is a complex mechanism takes place in angiosperms in which a female gametophyte fuse with two male gametes. In this process, pollen grains pollinate the female reproductive structure which is the stigma of the carpel.

The double fertilization process includes two male gametes, one of the gametes fuses with the egg cell and fertilizes it which forms the zygote whereas other gamete fuses with the nuclei cell which is two in number to form the endosperm.

Thus, the correct answer is option A. diploid zygote and a triploid endosperm.

BaLLatris [955]

Livestock producers and  breeders rank livestock on their ability  to produce high quality, efficient breeding  animals and market-worthy <u>offspring</u>.

To be able to effectively evaluate breeding  and market animals is of vital economic importance for the animal markets. The same traits  used to evaluate <u>high-grade slaughter  animals</u> are also important in the <u>grading </u>of  <u>breeding stock</u>.

When we judge livestock we  classify them as:

  • Superior livestock
  • Average livestock
  • Inferior livestock

We are looking for  the most desirable traits to fit our  particular market and genetic needs. The "Livestock Judging Manual" indicates that some of the most prevalent traits necessary to score a better rating are:

  • <em>Live weight</em>
  • <em>Fat depth</em>
  • Muscling

and many more. The most important of which is muscling given that an animal with more muscle will produce more desirable meat for the average consumer, and therefore can be sold at higher prices.

Musya8 [376]
The answer to this question is lactic acid. The reason why sports psychologists would need to look for a buildup of this chemical is because it is the chemical that produces pain or "feeling the burn" in an exercise when someone pushes their limit. Also, after so long, a person with a lactic acid buildup needs to take a break because high levels of lactic acid is dangerous for the bloodstream.
