From the brightness of the light of course. If the brightness is increasing it means the the light source is approaching and if the brightness is decreasing it means the light source is leaving.
The light waves also follow the Doppler effect. However, instead of changing the sound, you know whether an object is coming or going through the brightness of the light.
Explanation:
The doppler effect is a physical phenomenon. This phenomenon allows us to perceive if an object is approaching or moving away through the wave effect that that object produces in relation to an observer. This is because when a wave is propagated the speed of that wave depends on the environment in which it is being emitted. For this reason, the speed of this wave will be constant even if the observer moves, but the frequency and movement of this wave varies in relation to the observer's position. In this case, the Doppler effect suggests that the sound waves are relative to the observer. You know if an object is coming in or out of the sound it produces. The light waves also follow the Doppler effect. However, instead of changing the sound, you know whether an object is coming or going through the brightness of the light.
Answer: a. Haploid spores are released to form zygotes, which grow into gametophytes.
A fern has two different stages of the life cycle; the sporophyte and gametophyte. In the sporophyte, spores are released. After this life cycle comes the gametophyte or the sexual phase, <span>haploid spores are released to form zygotes, which grow into gametophytes. </span>
I dont know what animation you mean about but i will give my opinion.
ATP are used for energy, they are made inside mitochondria. Mitochondria use oxygen and food to make ATP, which is maybe what u mean by rechargable is because whenever you eat, the mitochondria will produce energy again and again.
A stretch of DNA that code for specific proteins is said to be a gene. A gene is transcribed into mRNA. The mRNA has a nucleotide sequence complementary to the corresponding gene. The nucleotide sequence of mRNA is read in the form of genetic codes during the process of protein synthesis to specify the amino acid sequence of proteins. Therefore, genes carry the genetic information for the assembly of proteins and the processes of transcription and translation deliver the stored genetic information.
