The lungs are considered to be an organ.
Answer:
b) and c)
Explanation:
Greenhouse gases are gases found in the atmosphere that absorb infrared radiation and trap the sun’s heat, thereby producing an effect known as <em>greenhouse effect.</em> By this natural way, the earth is able to be kept warm at an optimal temperature, to make it habitable for humans and other organisms. These gases referred to as <em>greenhouse gases</em> include, carbon dioxide, methane, water vapour and other trace gases found in the atmosphere. Greenhouse gases could be likened to the glass in a greenhouse that helps in trapping heat to keep the greenhouse warm at optimal temperature necessary for plant growth and development.
Without this natural greenhouse effect caused by greenhouse gases, life on earth would be almost impossible as the earth would almost be covered with ice below 0 degrees Fahrenheit.
The increased level of greenhouse gases we now find in the earth’s atmosphere is responsible for the additional warming of the earth’s surface, causing an enhanced greenhouse effect which results in global warming.
Statement a) cannot be used as an explanation because it is false. Greenhouse effect makes the earth habitable.
Statement d) cannot be used as an explanation because carbon dioxide is not the only greenhouse gas that matters. Water vapour, CFC and methane also have impacts.
<em>Statement b) and c) are the best statements to use in explaining the true nature of greenhouse effect.

Answer: A cell is defined as the smallest functional units of the body
Explanation:
These cells are grouped together to form tissues, each of which has a specialised function, example blood, muscles, bone. Different tissues are grouped together to form organs with a special function. For example heart is an organ made up of muscles tissue, connective tissue, nervous tissue and vascular tissue. These tissues work in a coordinated manner and enable the heart to carry out the broader function of pumping blood continuously.
While organs are grouped together to form systems, each of which performs a particular function that maintains the body Internal environment and contribute to the health of the individual. For example the digestive system is responsible for taking in, digesting and absorbing food which involves a number of organs, including the stomach and intestines.
Therefore the statement that 'organs are large structures that keeps us alive" is a correct claim.
Answer: the. Population of the light red walking beans would grow because the red light from the explosion would help the light red kidney beans blend in.
