Answer:
A science teacher asked students to describe and explain an internal adaptation that allows for a specific function. Students wrote the following:
Student 1: Leaf frogs can change their appearance to match their surroundings.
Student 2: Birds have hollow bones, enabling them to fly.
Student 3: Penguins live together in groups.
Student 4: Musk ox have thick, shaggy hair to protect them from cold temperatures.
Which student’s answer describes and explains an internal adaptation that allows for a specific function?
Explanation:
Answer:
25%
Explanation:
If they are both heterozygous, it means they both have a Dd genotype. If you draw out a punnet square Dd x Dd you end up with the following possible genotypes for the puppy:
DD, Dd, Dd, dd
In order for the puppy to be deaf, it must be dd since deafness is recessive, which is 1/4 (25%)
Answer:
Acid rain refers to the rain which acidic in nature having a form of precipitation and elevated levels of hydrogen ions (low pH). The normal pH of rain is around 5.6
Rising concentration of Sulfur dioxide (SO2) and nitrogen oxides (NOx) in atmosphere is one of the cause of acid rain. Sulfur dioxide (SO2) and nitrogen oxides (NOx) are released by vehicles, fossil-fuel power plants and oil refineries.
When a sulfur dioxide and nitrogen oxides released in air they mix with oxygen, water and other chemicals in the air and form sulfuric and nitric acids. sulfuric and nitric acids mix with precipitation and its pH level is about 5.2 or below.
Hence, rising concentration of SO2 And NO2x is one of the biggest reason of acid which damages agriculture, buildings and wildlife et-cetra.
