When coal is burned the sulfur mixes with oxygen and the sulfur oxides are emitted to the atmosphere. Sulfur dioxide (SO2) becomes sulfur trioxide (SO3) when responding with oxygen in the air.
How does combustion cause acid rain?Power plants remove the major of sulfur dioxide and of the nitrogen oxides when they burn fossil fuels, such as coal, to make electricity.
The from cars, trucks, and buses remove nitrogen oxides and sulfur dioxide into the air. These pollutants leads acid rain.
Hence, This reaction with water elements in the atmosphere to form sulfuric acid, a strong mineral acid. This makes rain acidic.

Phenotype is referred to as the expressed trait that is caused by a certain combination of alleles.
What is phenotype?Phenotype is referred to as the expressed trait that is caused by a certain combination of alleles. We will recall that the HbS allele is responsioble for the anemia that results from sickle shaped red blood cells.
This phenotype is both harmfull and benefical in the sense that it leads to the agglutination of the red blood cells in individuals that have this phenotype and eventual crisis. Also, it is beneficaila in that nthose who possess this phenotype do not suffer from malaria in the tropics.

Add a few toy houses in various places along the riverbank in your model. Your houses should be on top
of the sand, and directly on the river's edge. Describe what happens to the houses over time as the water
flows through the river. Based on your observation, describe the negative impact erosion can have on
human settlements around rivers.
In task 2 I only did part D
answer:
Two independent sets of observations on sand activities in relation to the flowing river are recorded as the water passes through the meandering river. Stream abrasion can affect the morphology of a stream or river dramatically over time. Because the water can start erosion with anything near it, erosion can impact human communities near rivers.

If an organism's DNA contains 33% adenine nucleotides and 17% guanine nucleotides, what percentage of its DNA is composed of cytosine nucleotides
A DNA with 33% adenine and 17% guanine nucleotides respectively will contain 17% cytosine.
Purine to Pyrimidine ratio in DNAAccording to Chargaff's rule, the ratio of purine to pyrimidine bases in DNA is constant.
Since adenine always pairs with thymine and guanine always pairs with cytosine, adenine to thymine and guanine to cytosine ratios would be constant as well.
Thus, if a DNA contains 17% guanine, it will also contain 17% cytosine.

Many of the factors that led to the late Permian mass extinction also contributed to the late Cretaceous mass extinction, with the exception of a meteor strike.
Permian-Triassic extinctionThe biggest mass extinction event in Earth's history occurred about 250 million years ago and wiped out 96% of marine life and 70% of land life. Known as "the great death", it was a period of extreme volcanism on the planet, in the region of Siberia.
Cretaceous-Paleogene extinctionOccurred only 66 million years ago, it decimated 75% of species. All non-avian dinosaurs were killed. Unlike the previous ones, this event was caused by an external agent: an asteroid over 13 kilometers wide plunged into Earth at 72,000 kilometers per hour.
