Are there answer choices?
Regardless, for the chemical equation to move accurately, energy/sunlight should be add on the top of the arrow.
Hope this helps c:
Answer: 9x10-3ms-1 -- A
Explanation:
Given wavelength λ = 505nm
1nm= 10^9m
505nm = 5.05 x10 ^-7m
and speed of light, c is 3.8 x 10^ 8
frequency = ?
Using frequency = speed of light / wavelength
f = c/λ
Frequency , f= 3.8 x10^8m/s/ 5.05 x10 ^-7m
=5.94 x 10 ^14 s⁻1
Also Energy = hv
where h =Planck constant = 6.626 x10 ^ -34 J.s
v= frequency =5.94 x 10 ^14 s⁻1
Energy = 6.636 x10 ^ -34 J.s x5.94 x 10 ^14 s⁻1
= 3.935 x 10 ^-19J
Given
9.5×10 −12 g as the mass of the bacterium,
changing to kg
1000g= 1kg
9.5×10 −12 g = 9.5×10 −15kg
to find the velocity
Energy = 1/2mv² = E=1/2mv²
v=
=
v =0.009099= 9x10-3ms-1
The correct answer is A. Scientists reintroducing crested toads into the wild.
Explanation
Species Survival Plan is a conservation program promoted by conservationists and zoologists that specializes in those animals that are near extinct, endangered, or threatened. This program mainly aims to breed these species in captivity to ensure their future preservation and reintroduction to nature. According to the above, the effect that could be expected from the implementation of the Species Survival Plan in Puerto Rico with the crested toads would be the reintroduction of this species into the wild after being bred in captivity.
Answer:
1. The process in which organisms find and colonize a near lifeless area.
2. They are different from each other because secondary supports life, as primary does not.
3. Pioneer species is a hardly classified species which establish themselves in a disrupted ecosystem and trigger the process of ecological succession.
4. Biotic factors support life and the aspects. Abiotic factors involve external life. They interact with each other when the abiotic provide for the biotic.

Answer:
A) actin and myosin is a correct answer.
Explanation:
- Myofibrils are the contractile fiber and they are made of actin and myosin.
- Myofibrils are made of thick myofilaments and thin myofilaments.
- Thick myofilaments are made up of myosin whereas thin myofilaments are composed of actin.
- The functional unit of muscle is Myofibrils and contraction of muscle occurs due to myofibril, when the filaments actin and myosin interact with each other.
Thus Myofibrils are made primarily of (A) actin and myosin.
