Answer: polymers
A polymer are large molecules made up of repeating units, referred to as monomers.
Explanation:
Polymers are macromolecule with large size and high molecular mass. They consists of several repeating units of simpler molecules known as monomers.
Examples of polymers found in plants are
- starch composed of several glucose units linked by glycosidic bonds
- cellulose composed of several repeating glucose units linked by glycosidic bonds as well
An example of polymers found in animals is
- glycogen composed of several units of glucose monomers linked by glycosidic bonds
It is D: a spinning cloud of dust...
Radioactive decay or disintegration is a process through which unstable nuclei form q more stable nuclei by the release of elementary particles like alpha particles, beta, protons, neutrons etc along with the release of energy.
In the given examples:
a) N-13 will get converted in to carbon, C-12 along with the release of a proton as shown below:
₇N¹³ → ₆C¹² + ₁H¹
b) N-15 will get converted in to boron B-11 along with the release of an alpha particle
₇N¹⁵ → ₅B¹¹ + ₂He⁴
Answer:
To survive Global life expectancy is the highest it's ever been, with a global average lifespan of about 71.4 years as of 2015.
Explanation: took the test
Simply put, MA = Force Out / Force in. That's the way it is usually stated. The force out is normally what you need to move. The force in is what you need to supply to get the force out. Most machines will give you an MA of more than 1. Some (like your arm) will give you less than 1 and others (like this one) will give you exactly one.
This one is frictionless, otherwise it would slip into less than one if it had friction.
Answer B
