Farming causes a chain reaction: farmers supply crops/meats to distributors, distributors sell crops/meats in bulk to grocery stores, and those in the food industry can obtain their produce through the mentioned grocers. Restaurants rely on grocers, who rely on distributors, who rely on farmers.
1. Galactosemia is a disease that will only be expressed when a person is<span><span><span> homozygotic recessive for that trait. It's the same as saying it </span> has</span> 2 recessive alleles.
Dominant allele-</span><span> G
recessive allele- g
</span>
Homozygotic dominant: GG <span><span>(doesn't express the disease)
</span>Heterozygotic : Gg (doesn't express the disease)
Homozygotic recessive: gg (expresses it)</span>
2.
-Mary has this genotype: G_ . This means it can be GG or Gg
-The exercise already says that justin's mother is GG (<span>Homozygotic dominant)
</span>- If his mother is GG, one of these G's is going to be passed to Justin. So, his genotype is either GG or Gg. Since we are not sure we write as: G_.
Justin's genotype: G_
3.
-Justin's uncle has galactosemia so his genotype is: gg
-If the uncle was able to receive two recessive alleles it means the mother had one to pass, and so did the father. However, in the diagram, it's not pointed out that they have a disease so it only leaves one possible genotype: Gg. Justin's grandparents are both Gg.
4. The last person to analyze is Justin's father.
If we crossed the grandparents (Gg x Gg) we could obtain these genotypes: GG, Gg, gg.
Justin's father doesn't express the trait, so it's not gg. That leaves us with either GG or Gg. Since we can't know for sure, onece again we write as G_
Justin's father: G_
"To facilitate the faster movement of naval ships from the Atlantic to the Pacific" reflect one of the reasons for America's interest in the Panama Canal.
<u>Answer:</u> Option E
<u>Explanation:</u>
Panama Canal is an artificial or man-made waterway of 82 km located in transcontinental country in Central America and South America named as "Panama". France was the very first nation to start work on the canal in 1881 but after some engineering issues they eliminated themselves from the project.
In 1901 the United States leaded the project which finally resulted into inaugural ceremony of the panama canal on 15th August, 1914.The bypass, one of the largest and most complex engineering projects ever undertaken, significantly reduced the time for ships to pass between the Atlantic and Pacific oceans. Therefore it allowed them to avoid the long, risky Cape Horn path around the southernmost tip of South America via the Drake Passage or Magellan Strait.
Pioneer species can decrease if other species move it out. If the pioneer species in a forest area is a type of bush, that bush might decrease in number as more species come in.
