1.) Sexual reproduction increases genetic diversity in many species of plants and animals because of meiosis. During meiosis, crossing-over occurs and changes up genes in the chromosomes. Each gamete (sperm and egg), have half the chromosomes (23) and combine to have 46 chromosomes. This is how you get traits from your parents that make you different.

2.) Asexual reproduction occurs when a single parent copies its own DNA and genes and grows an identical version or clone of itself.

A charged particle of mass m = 5.00g and charge q = -70.0μC moves horizontally to the right at a constant velocity of v = 30.0 k
pychu [463]

Answer:

The magnitude of the force, B = 5 Tesla, Up (North) direction

Explanation:

Magnetic force F= Eq where Electric field, E = 750 NC

and charge, q = -70 μC = -7 ×10^{-5}C

F = 750 ×  -7 ×10^{-5}

F = 0.0525

But F = qvB; B = \frac{F}{qv}

where B is the magnetic field

= 0.0525 ÷ ( -7 ×10^{-5} × 30)

B = 5.0 Teslas

The force on a negative charge is in exactly the opposite direction to that on a positive charge.

Hence the direction of the charge is up (North).
