Answer:
The correct answer is - Cyanobacteria; Horizontal gene transfer
Explanation:
According to the endosymbiotic theory it is believed that the eukaryotic plastids (mitochondria and chloroplasts) have developed from symbiotic bacteria, such as cyanobacteria and alpha-proteobacteria.
During this symbiotic process, some genetic material may have been move in between the symbiotic counterparts in a process called Horizontal gene transfer or lateral gene transfer.
thus, the correct answer- Cyanobacteria; Horizontal gene transfer
I think it’s B
Hope that’s right
B. An ecosystem in which plant roots are submerged during parts of the years
Answer:
d. eon, era, period, epoch
Explanation:
The geological time scale has been made so that the scientists can have a practical system about the classification of geological time, thus everything that has happened throughout it. The geological time unites have been defined in accordance with important events that have happened, thus marking their end or beginning. These events can be mass extinctions, catastrophes, climate patterns, domination of certain species etc. The longest of these time units is the eon, lasting for more than half a billion years, and up to 2 billion years. The era comes as the second longest time unit, lasting for several hundred million years. The period lasts for several tens of million years, and the epoch is the smallest unit, lasting for few million years, or several hundred thousand years.
As white light passes through a prism, the light is separated into the different colours of light that we see and this is called the visible spectrum. Each colour of light has a different wavelength. The wavelength is inversely proportional to the energy of that light. As the wavelength increases, the energy decreases and vice-versa. The relationship is:
E = h/λ, E is energy, h is Planck's constant, and λ is the wavelength.
Therefore, the answer is B) different amounts of energy in white light.
