Answer:
Mitosis is a type of cell division in which a parent cell divides into two identical daughter cells, each with the same number and kind of chromosomes as the parent cell.
When a parent cell divides more times than usual during mitosis, the division of chromosomes between the chromosomes would not be proper. For example, a daughter cell may end up with one chromosome less than the parent cell. This ultimately results in genetic disorders.
Answer:
To have a positive job, the two vectors must have the same direction
Explanation:
Work is a scalar defined as the scalar product of two vectors, the froce and the displacement. To have a positive job, the two vectors must have
collinear and that their arrows point in the same direction.
You can also appreciate this from the work equation
W = F. r
bold indicate vector
W = F r cos θ
With θ the angle between force and displacement
They are called magnets poles.
Remember that the left is NEGATIVE
and RIGHT is POSITIVE
16. +3N - 6N = -3N
therefore 3N to the left (because left = -)
17. +5N - 5N = 0N , zero resultant force
18. +6N - 4N = +2N
therefore 2N to the right (because right = +)
Explanation:
Kepler's third law gives the relationship between the orbital radius and the orbital period of the planet. Its mathematical form is given by :
Here,
G is gravitational constant
M is mass of sun
It means that the mass of Sun is constant for all planets orbiting the sun, assuming circular orbits.
