Answer:
Explained below.
Explanation:
At least three forms of force when dropping a ball on the ground are gravitational force, air resistance force and the buoyancy force as well.
→ Gravitational force is a type of force that is acting while the ball is dropping, that is the downward force which is attracting the ball towards the centre of the surface of the earth.
→ Air resistance force is the upward force that will be acting while the ball is dropping on the ground.
→ The buoyancy force is the type of force that will act when the ball will touch the ground, then due to buoyancy force, the ball will bounce.
The squirrels are attuned in their brains to understand that owls are a threat because it is a predator. This is visual stimuli that evolved over many years to elicit a conditioned response. This is an innate behavior (meaning that it has been pre-programmed into an animal's genes) and offspring are naturally born with it.
The correct answer is A) bb
Explanation:
In genetics, an allele is a variation of a gene, which often determines a physical trait. Alleles are classified as dominant if they express even when there are other alleles or as recessive if two copies of the same allele are needed for the gene to express. Moreover, in genetics dominant alleles are represented by uppercase letters while recessive alleles are represented by lowercase letters.
In this context, the allele that is responsible for the brown coat in rabbits is a recessive allele, considering this is represented by lowercase b. This means two copies of the allele are necessary for the rabbit to have a brown coat and therefore the genotype of a brown coat is bb. Also, others such as Bb and BB have the dominant allele related to the black coat, and therefore will lead to rabbits with a black coat.
