Correct answer: C). Weather balloon
A weather balloon is a type of balloon that holds an instrument that sends back the information on atmospheric pressure, humidity, temperature and the wind speed by the radiosonde.
The balloon is held at a constant height for a long period of time. These are used to measure weather conditions higher in the atmosphere.
Hence, the correct answer would be option C.
Greenhouse gases are gases that have been shown to contribute to the phenomena called the "greenhouse effect" or the idea that higher rates of certain gases in the atmosphere are causing a gradual rise in the planets temperature. Common greenhouse gases are gases that are generally released through the burning of fossil fuels. These fuels include carbon dioxide (co2), methane (CH4), Nitrous Oxide (N2o), CFCS, and Water Vapor (H2o).
Answer:
Where and in what arrangement organisms are located
Explanation:
A population distribution shows where and in what arrangement organisms are located.
Answer:
The statements are correct.
Explanation:
Cell culture is a technique widely used in molecular biology where cell lines are grown in controlled conditions, thus allowing to make experiments and to test compounds that may result useful to treat diverse diseases, including cancer.
Immortalized cell lines are characterized for their ability to proliferate indefinitely which are derived from oncogenic tissues. In cancer research, these lines are used as models to test different drugs and to study cellular mechanisms associated with cancer progression including, among others, proliferation, invasiveness, vascularization, etc. In addition, the mechanisms associated with the death of cancer cells such as, for instance, apoptosis, may also be studied by using immortalized lines.
Answer:
Saliva contain enzymes.
Explanation:
In the mouth, when chewing a bite of bread, it mixes with the saliva in the mouth which is secreted by the salivary gland. The food is broken down by chewing which is converted into Bolus through the saliva. The saliva comprises of digestive salivary amylase which help to digest carbohydrates and breakdown carbohydrates into smaller pieces.
Bread is a carbohydrate, digestive salivary amylase breakdown bread into sugars.
Therefore, digestion begin from the mouth and it contain saliva which comprises of the enzymes.
