Answer:
Viruses exhibit two out of above mentioned which are
1. They contain genetic information
2. They reproduce
Explanation:
Viruses can be classified as either living or non living organisms
They can be classified as living organisms because of the following reasons
1. They can mutate
2. They can grow
3. They evolve to adapt to their hosts
4. They are capable of multiplication in their host cells
5. They are made up of proteins and glycoproteins like cells do
6. They have genetic information which helps them to produce more viruses in the form of either RNA or DNA.
They can also be classified as non living organisms because
1. They can not exist outside their host cell
2. They do not carry out metabolism, they make use of their host mechanisms
Answer:
The correct answer is "preservation of wetlands".
Explanation:
Wetland are areas of lands that are saturated with water, usually comprised by marshes or swamps. Preservation of wetlands help to reduce the risk of floods because wetlands temporarily store and slow the release of stormwater. It has been reported that areas where wetland have been lost, the chances of flood increases by as much as 80 percent. The government of a flood-prone region would likely reduce the risk of floods by preserving its wetlands.
Answer:
The gene that controls production of white blood cells.
Explanation:Gene expression within the body is controlled by the cells, which determine when a specific gene should or should not be expressed. Influenza (the flu) is caused by a virus that attacks the respiratory system
Answer:
The correct option is B) a pattern of biological functioning that occurs on a 24-hour cycle.
Explanation:
Biological rhythm is defined as the regular variation of an organic function related to the course of time, circadian biological phenomena (around the day), are those with a period of approximately 24 hours.
Circadian rhythms are physical, mental and behavioral changes that follow a daily cycle (the biological rhythm), and that respond primarily to light and darkness in an organism's environment. This cycle close to 24 hours, allows to recognize the sleep-wake phenomena and their homeostatic action, in the systemic processes of every living being. The circadian system is composed of photoreceptors, pacemakers and efferent pathways that allow a regular functioning of the sleep and wakeful state.
