Explain how lines of latitiude and longutitude help people find locations on earth

Biology
1 answer:
san4es73 [151]3 years ago

Lines of longitude and latitude help people in finding locations  by making the location easier with accuracy on a globe. For example if you had 90 degrees longitude west and 40 degrees latitude east. The lines in which those two intersect is the location. This makes locating very easy and this is what pilots use to travel to different locations.

Drilling for fossil fuels.

This is because the main fossil fuels are not typically found in the rainforest. To also back up this claim, use the process of elimination.

The last choice, demand for rainforest products, is obviously incorrect as that would mean expansion into the rainforest to gather said products.

Shortage of food sources wouldn't be the correct answer either as food sources aren't typically found in the rainforest among popular demand and food can be shipped into the country as well. 

Overcrowding in cities would also lead to expansion, where to can differ based on location but to rainforests or anywhere surrounding the area would be preferred or desirable.

Hope this helps!

Which of the following explains why water is a good solvent for polar and ionic compounds?
Anni [7]

Hi there!

<u>Electronegativity</u> is the concept of how likely an atom is to attract the shared molecules in one of these bonds to itself. We know the molecule water is made up of two hydrogens and one oxygen. The electronegativity of hydrogen is 2.2, and oxygen 3.4. An <u>ionic bond</u> needs at least a difference in electronegativity of 1.6. As the difference is less than that, we can say that water is a covalent molecule. This then wipes out choice B, because it is not ionic, and C, as we have seen it is actually covalent.

Now, we can see the difference in electronegativity between oxygen and hydrogen is still 1.2. This means that while it is not at the point for there to be an ionic bond, there is still a difference in attraction, where the electrons will tend to favor the oxygen more and 'hang around it' more. As electrons are <u>negatively charged</u><em><u>,</u></em> this means that the oxygen will gain a slightly negative charge. This then makes the molecule polar, because it now has a charge within the molecule. This means we have our answer, choice D.

In terms of hydrophobic molecules - they tend to be ones without a charge. (If you're interested in this kind of stuff, I'd search hydrophobic up, and possibly also look into hydrogen bonds).

Hope this helps! Feel free to ask me any other questions you have about this specific problem.

What effect would there be on the final daughter cell if the spindle fibers failed to pull a chromosome toward the pole, as in c
allochka39001 [22]

Aneuploidy can result in the final daughter cell if the spindle fibers fail to pull a chromosome toward the pole as in case of non-disjunction.  

Explanation:

Aneuploidy is a condition which arises when one or more chromosome is missing in the final daughter cells.

Non-disjunction refers to the failure of chromosomal or chromatid segregation or separation during cell division. This results in erroneous meiosis or mitosis leading to the formation of final daughter cells or gametes with an extra or missing chromosome. This condition is aneuploidy.  

Failure of separation or segregation of:

  • Homologous chromosomes occur in Anaphase I, affects four daughter cells.
  • Sister chromatids during Anaphase II, affects two daughter cells

This failure of separation leads to aneuploidy chromosomal abnormalities like monosomy, trisomy, etc which can cause diseases like Down’s syndrome, Turner’s syndrome etc.
