I believe it is D With the help of my notebook
Answer:
Ratio = 9 : 2
Explanation:
We have been given two resistors, one with 2ohms rating and another with 4 ohms rating.
First they are connected in series. When resistors are connected into series, Equivalent resistance is given by:
Resistance (Equivalent) = R₁ + R₂ = 6 ohms
When these are connected in parallel, equivalent resistance becomes:
1 / Resistance (Equivalent) = 1/R₁ + 1/R₂ = 1/2 + 1/4
1 / Resistance (Equivalent) = 3/4
Resistance (Equivalent) = 4/3
Ratio = R(Series)/ R(Parallel)
Ratio = 6 : 4/3
Ratio = 18 : 4
Ratio = 9:2
Answer:
A. Predation
Explanation:
Predation involves an organism or animal feeding on other animals as a source of food without the addition of other animals who also eats the same source of food as it.
The scorpion and moth are active at night. Scorpions feed on moths and other insects that are also active at night. This only talks about the Scorpion and the various food sources it has which include moth and other night insects
Genetic variation is essential for natural selection because natural selection can only increase or decrease frequency of alleles that already exist in the population. Genetic variation is caused by: mutation. random mating between organisms.
