All living organisms have ways of maintaining homeostasis. They have mechanisms for controlling such factors as their internal temperature, water balance, and acidity. Homeostasis is necessary for normal life processes that take place inside cells.

Correct answer: A). Forecasting weather
A weather radar is an instrument that is used to locate precipitation, calculate its motion and determine the type i.e hail, snow or rain. It sends electromagnetic energy pulse into the atmosphere. If that pulse of energy interacts with something, then it reflects back the energy, which can be sensed by the weather radar. 
Nowadays, most radar used are Doppler effect, which has dual polarization, it determines that movement is toward or away from the radar.
Hence, the correct answer would be option A.
 
        
                    
             
        
        
        
Answer:
Explanation:
The more similar the two species are, the more their niche overlaps and the more competition there is.
<em>The most interesting results obtained in animal models of passive immunotherapies developed according to the “amyloid-beta cascade hypothesis” and the “Tau hypothesis” are monoclonal antibodies that directly or indirectly target Aβ plaques or neurofibrillary tangles. Unfortunately, these therapeutic antibodies cannot replicate their promising effects on humans at the clinical phase. Despite this, we still hope to learn from these failures and to explore new pathways. The great effects obtained in animals with passive immunotherapy suggest that this technology may be an important key to curative treatment. The remaining challenge is to find a way to achieve the same encouraging results for humans. Alzheimacy expects to join hands with global partners to focus on the development of therapeutic antibodies for Alzheimer’s disease (AD) and continue to fight against this disease.</em>
