A scientific model can be used to test a hypothesis.
Answer:
Option C, No. The energy contained within these macromolecules is converted into other forms of chemical energy and kinetic energy, though some is lost as heat.
Explanation:
Breaking down of large molecules in to smaller molecules does not signify breaking down of energy stored in it and hence losing all the stored energy.
Breaking down of large molecule is necessary to convert large molecules into small easily digestible molecules so that the food energy stored in them can be stored in some other form specifically chemical energy and can be used at later stages. However, in the process of conversion of large molecules into small molecules , a certain amount of heat energy is used.
Hence, option C is correct
Answer:
e. bacteria producing vitamin K
Explanation:
Microbial antagonism basically refers as microbes versus microbes i-e the indigenous microflora serve a beneficial role by preventing other microbes from becoming established in or colonizing a particular anatomic location in the body.
As all the options mentioned, refers to the microbial antagonism except option E as the normal microbes protect the host by :
1) Producing acids.
2) Bactreocin production
3) By occupying the niches that the pathogens may occupy.
But the microbes cant compete with other microbes by producing vitamins and growth factors that can be utilized by the host.
Hence option E is the right answer.
Answer:
Yes
Explanation:
There are alternative forms of storage molecule gathering.
