Answer:
Carrying capacity is the maximum populations size of species that can be sustained continuously.
Explanation:
True
Evolution occurs when an organism is born with a mutation and passes that mutation on to its offspring.
Explanation:
Reproduction in Fishes. Nearly all fish reproduce by sexual reproduction - the fusion of sperm produced from testes and eggs produced from ovaries. ... Fertilization is external in most fish species. Large quantities of eggs and sperm are simultaneously released into the water by females and males.
Answer:
Angular speed of the bacteria motor is 1447rad/s
t = 4.342 × 10^-3 seconds
Explanation:
Hint: Do you remember circular motion in physics???
Okay, let's go
Given:
radius of 1.61 10-8 m
tangential speed at the rim of 2.33 10-5 m/s
Let's recall that angular velocity
ω = Vt/r
Where,
Vt = 2.33 10-5 m/s
r = 1.61 10-8 m
ω = ?
ω = 2.33 ×10-5 m/s = 1447rad/s
1.61 ×10-8 m
Angular speed of the bacteria motor is 1447rad/s
Let's find the elapsed time too
Since The angular velocity is said to be constant, there will be no acceleration (a = 0)
Using:
θ = ωot + (1/2at^2)
t = θ/ωo
(θ = 1 revolution or 2π rad, ωo = 1447rad/s)
t = (2π rad)/(1447 rad/s)
t = 4.342 × 10^-3 seconds
