Answer:

variations in great horned owl body size due to food supply can be acted on by natural selection.

Explanation:

Natural selection can help select great horned owl with smaller body size since it's an advantage in a place with smaller available food sources, compared to a bigger body size that will need more food. At first, birds with smaller body survive while those bigger ones die out, and the smaller birds pass on this genes to their offspring.

Answer:

variation in body size due to inherited traits can be acted on by natural selection

Explanation :

Variations in body size in body size due to inherited trait can be acted upon by natural selection by favoring the size that is best suited for the survival of the species. Those with these genes survive and pass it on to their offspring, while those with the unfavorable body size are wiped out.

How can you say metre cube is a derived unit​
riadik2000 [5.3K]

Answer:

The newton (lowercase n!) is a derived unit because its definition consists of multiplication of three defined base units and nothing else. Its meaning is thus derived, not independently defined.

State Coulomb’s Law equation and give the meaning of every variable and the units.
igor_vitrenko [27]

The Coulomb's law equation is  F = Kq₁q₂/r².

<h3>What is Coulomb's law?</h3>

This is the law that relates the product of two charges to the square of distance between the two charges.

Coulomb's law states that the force of attraction or repulsion is directly proportional to the product of the charges and inversely proportional to the square of distance between the charges.

<h3>Coulombs' law equation</h3>

The equation of Coulomb's law is given as;

F = Kq₁q₂/r²

where;

  • K is Coulomb's constant, Nm²/C²
  • q₁ is the first charge, C
  • q₂ is the second charge, C)
  • r is the distance between the charges, m

Thus, the Coulomb's law equation is  F = Kq₁q₂/r².
