I'll do my best to help, but do keep in mind that this is just an educated guess on my part.
Characteristics of Living Viruses:
- Uses energy (nonliving things can't use energy, for obvious reasons)
- Exhibits growth and development (for the same reasons as above, nonliving things can't grow)
- Made up of one or more cells (cells are alive, so nonliving viruses can't be made up of living things)
- Possesses internal organization (viruses can be complex, as most living things are)
- Eliminates waste
Characteristics of Nonliving Viruses:
- Defined boundary (this is a bit vague because a defined boundary isn't suggestive of life or not, so it could really be either or)
Because most of the answers fit with the living characteristics, it makes me think there is something wrong with my answer, but I did some research and that seems pretty accurate. However, I'm not a professional, so I could be wrong. I'm sorry I couldn't help more
Mouth - break down food mechanically and chemically
Salivary Glands - produce saliva that contains enzymes which chemically break down food
Esophagus - move food from mouth to stomach through a process called peristalsis
Stomach - chemically break down food with stomach acid, mechanically break down food with the contracting of stomach muscles
Liver - creates bile that helps with digestion, stores, distributes and breaks down nutrients
Gallbladder - temporarily stores bile and squeezes it into the small intestine to break down fat droplets
Pancreas - produces pancreatic juice that contains digestive enzymes and bicarbonate
Small Intestine - absorbs nutrients from chyme
Large Intestine - absorbs water and dries out food, turning it into waste
Rectum - stores waste before it leaves the body
Anus - an opening where waste exits the body
Answer:
An extreme version of scoria occurs when volatile-rich lava is very quickly quenched and becomes a meringue-like froth of glass called pumice. Some pumice is so full of vesicles that the density of the rock drops low enough that it will float
Explanation:
Answer:
5
Explanation:
The Hardy-Weinberg equilibrium principle says that allele frequencies in a population will remain constant in the absence of the four factors that could change them. Those factors are natural selection, mutation, genetic drift, and migration (gene flow). In fact, we know they are probably always affecting populations.
