Answer:If plants were only exposed to green light the rate photosynthesis would decrease. amount of carbon dioxide would increase.
Explanation:
Chlorophyll a: This is the most abundant pigment in plants. Chlorophyll absorbs light with wavelengths of 430nm(blue) and 662nm(red). It reflects green light strongly so it appears green to us.
The gas state. When water boils, it releases a gas we know as steam.
A radioactive element is an element which is subject to spontaneous degeneration of its nucleus followed by the emission of alpha, beta and gamma particles. All elements with atomic numbers greater than 83 are radioactive.
The given phrases that describe radioactive elements are-
They have a consistent number of particles
- the particles are alpha, beta and gamma particles.
They have a half-life that determines their rate of decay.
Explanation for other options:
Not all elements occur in nature. Radioactive decay rates may not be constant as the decay happens when a radioactive substance emits a particle. It is not possible to predict exactly when a given atom of a substance will emit a particular particle. When the radioactive element release energy and particles, it decays.
