The map illustrates the greenhouse gas emissions by country in 2000. What statement correlates the map with the ecological footp

rint of the country?
A)Only larger countries impact greenhouse gas levels on a global scale.

B) Less developed countries have equivalent greenhouse gas emissions to industrialized nations due to their reliance on burning biomass for fuel.

C) The United States has a smaller population than China, but has a higher per capita greenhouse gas emission, resulting in a larger carbon footprint on a national level.

D) Although the United States and China are roughly the same geographical size, the United States must have a larger population of citizens to result in a higher level of greenhouse gas emissions.

Alu element at the PV92 locus on Chromosome 16. In this population, 436 people have a heterozygous genotype and 102 people have
Lesechka [4]

Answer:

Explanation:

According to the exercise we can infer that for the Alu insert:

p: positive allelic frequency

q: negative allelic frequency

maintaining that the population is in equilibrium we can carry out the following formula

p + q = 1 and pp + 2pq + qq = 1

looking for the genotype frequency we clear and obtain the following data

genotype frequency of 2pq = 436/1000 = 0.436

The genotype frequency of qq = 102/1000 = 0.102

This is how we look now:

number of positive people for Alu = 1000- (436 + 102) = 1000- 538 = 46

In this way it is resolved that:

genotypic frequency of pp = 462/1000 = 0.462

  p = 0.462 + (0.436 / 2) = 0.462 + 0.218 = 0.680

q = 0.102+ (0.436 / 2) = 0.102 + 0.218 = 0.320

According to the exercise carried out it is deduced:

The value of p in the population is = 0.68

We conclude that our prognosis showing a homozygous positive genotype is: 0.462

<span>Which structure secretes digestive enzymes that break down carbohydrates, fats, and proteins? A. Pancreas

Most of the enzyme in the intestinal system is made by pancreas. Pancreas will also secrete insulin to make cell utilize glucose. The Large intestine is absorbing water. Salivary glands mostly digest carbohydrate.</span>

Before the presence of living organisms earth was a very different place match each fact about about Precambrian earth to the sp
Stolb23 [73]

The correct matches are:

- Atmosphere - Oxygen spilled into this sphere from ocean waters;

The majority of the oxygen in thee Precambrian Earth was not in the atmosphere, but instead it was in the ocean waters. With the emergence of life, large portions of this oxygen went into the atmosphere as it was released as a waste product.

- Biosphere - Cyanobacteria started to emerge as a life form;

The cyanobacteria were one of the earliest life forms. They were producers, and started to use the process of photosynthesis in order to produce food. The usage of this process caused lot of changes on the Earth later on.

- Hydrosphere - Oceans contained far less salt than they do today;

The rocks and minerals in the Precambrian Earth were not weathering and eroding in the manner they are now. Instead they were kept compact for much longer periods, influencing the mixture of of different components with the water as well in meantime.

- Lithosphere - Oxidation in rocks and minerals was not possible;

Because there was way to small amount of oxygen in the atmosphere, very close to 0%, the oxidation of rocks and minerals was not possible, as the oxygen is the gas that causes this process.
