Answer:
b. ecosystems in a region, species in an ecosystem, and genes and alleles in a species.
Explanation:
Biodiversity has three levels - ecosystem, species and genetic diversity. Therefore, Biodiversity can be defined as the variability among living organisms involving terrestrial, marine, and other aquatic ecosystems, genes and alleles in a species and their ecological complexes such as diversity within species, and between species of the ecosystems.
Answer: It occurs when iron and oxygen go through a chemical reaction similar ... A substance that starts a chemical reaction is called a reactant, and a substance that forms as a ... baking involves the use of energy to produce chemical reactions. ... Answer the following questions about the equation you saw above: ..
Explanation:
Options for the question have not been provided. They are as follows:
A) somatic neurons in the spinal cord
B) the reticulospinal and vestibulospinal tracts
C) the vagus nerve and enteric plexus
D) the rubrospinal tracts
Answer:
C) the vagus nerve and enteric plexus
Explanation:
Enteric plexus or enteric nervous system is a part of autonomic nervous system and controls the gastrointenstinal (GI) tract. Vagus nerve is tenth cranial nerve and it innervates the enteric plexus. Both work together to control various functions of GI tract like peristalsis and gastric secretion. They release Gastrin-releasing peptide due to which the G cells of stomach are stimulated secrete gastrin. Gastrin in turn stimulates parietal cells of stomach to secrete gastric juice.
Answer:
A good example happens during the breakdown of food particles.
Explanation:
The chemical energy stored in food is a type of potential energy. Transformation of this energy into kinetic energy happens during chemical reactions that takes place during digestion. A good example of kinetic energy is therefore the breakdown of carbohydrates into carbon dioxide, water and heat.
Answer:
That happens during anaphase!
Hope this helped you! :)
