Answer:
Yes
Explanation:
Each person has two alleles (forms of a gene) for a characteristic. We can represent them using letters.
Dominant trait are written as capitals. If a dominant allele is present in someone's genotype, the dominant trait will show.
The recessive trait only shows if a person has two recessive alleles.
Brown eyes is a dominant trait, and blue eyes is a recessive trait.
B = dominant brown eyes
b = recessive blue eyes
If someone has <u>brown</u> eyes, their genotype can be:
BB
Bb
If someone has blue eyes, their genotype is:
bb
The baby's genotype must be bb because it has blue eyes. <u>The baby gets one allele from each parent</u>.
See the photo for Punnett square. If the parents are both Bb, then they could each give the b allele, resulting in a blue-eyed baby.
Answer:
Eating food produce locally makes it where big trucks don't have to bring it to the restaurant
Explanation:
When the big trucks drive it they release pollutants into the air so therefore when you get stuff produced locally you don't have the big trucks polluting the air. So therefore it is better for the environment.
The law of conservation of mass says you don't create or destroy atoms in a reaction. So the total mass of reagents equals the total mass of the products.
Answer: The force constant k is 10600 kg/s^2
Step by step:
Use the law of energy conservation. When the elevator hits the spring, it has a certain kinetic and a potential energy. When the elevator reaches the point of still stand the kinetic and potential energies have been transformed to work performed by the elevator in the form of friction (brake clamp) and loading the spring.
Let us define the vertical height axis as having two points: h=2m at the point of elevator hitting the spring, and h=0m at the point of stopping.
The total energy at the point h=2m is:
The total energy at the point h=0m is:
The two Energy values are to be equal (by law of energy conservation), which allows us to determine the only unknown, namely the force constant k:
