Answer:
Credit for developing cell theory is usually given to three scientists: Theodor Schwann, Matthias Jakob Schleiden, and Rudolf Virchow. In 1839, Schwann and Schleiden suggested that cells were the basic unit of life.
Answer:
The two blue budgies are most likely to be yyBb each
Explanation:
there are 3 different scenarios possible for crossing blue budgies:
1) yyBB crossed with yyBB
this is not possible because it does not allow for the genotype yybb (white budgies)
2) yyBB crossed with yyBb
again, this cross will not yield the genotype yybb required for white budgies as given in the problem statement
3) yyBb crossed with yyBb
which leaves us with this option being most likely the genotype of the parent budgies who will have white budgies as offspring

Explanation:
6 m/s
This type of collision is a <u>Inelastic collision </u>
Explanation:
We begin by finding the momentum of the initial train car;
Remember that momentum is given by the formulae mass (kg) * velocity (m/s)
Therefore;
Momentum = 6000 * 10
= 60,000 kg⋅m/s
The other car has zero momentum because;
4000 * 0
= 0
When the two train cars collide, the total momentum will be;
60,000 + 0 = 60,000
Therefore to find the velocity, well use the same formulae;
p = mv whereby;
p – momentum
m – mass
v – velocity
60,000 = (6000 + 4000) * v
v = 60,000 / 10,000
v = 6
= 6 m/s
This is an elastic collision because we are assuming that no energy is lost in the collision. Most collisions, however, are not elastic but rather inelastic. In inelastic collision some of the kinetic energy is lost to the environment in some other form of energy such as heat energy.
