Answer: D. a genetic bottleneck
Explanation:
A genetic bottleneck also known as a population bottleneck is one that describes a sharp reduction in the size of a population caused by environmental events like in the above or caused by human activities.
This is the chemical formula for photosynthesis. Instead of just saying "Energy," however, it should specify solar energy, or light energy. Photosynthesis is the process of capturing solar energy and converting it to chemical energy.
It is true, because most of the steps of cellular respiration take place in the mitochondria. Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.
Answer: The answer is ROOT
Explanation: Briophytas belong to the plantae kingdom, therefore they have a cell wall in their cells, and chloroplasts. They have sporangia (structure where the spores are produced and stored) but they do not possess proper roots. Instead they have a structure called "rhizoid" whose function is the fixation to the substrate.
The correct option is D.
Noble gases are very stable, because they have eight electrons in their outermost shells. This is called octet form. Other elements that do not have the octet form try to achieve the form by forming bonds with other elements. Because of their stability, noble gas are chemically inert, that is, they do not undergo chemical reactions with other elements.
