The position of a particle moving along a coordinate line is s equals startroot 92 plus 4 t endroot, with s in meters and t in seconds. find the particle's velocity and acceleration at t equals 2 sec. the velocity at t equals 2 sec is nothing m divided by sec.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).

i think the answer is a, hope this : )

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
