Answer:
Epimysium
Explanation:
The muscle fibers of a skeletal muscle are surrounded by three layers of connective tissues to form a muscle. The three layers of connective tissues are –
a) Endomysium – It is the inner most layer of connective tissue that surrounds all the muscle fiber
b) Perimysium – This layer lies above the endomysium and forms a fascicle
c) Epimysium – This is the outermost layer of the connective tissue surrounding the skeletal muscle. Epimysium form a complete muscle by encircling the fascicle
Answer:
By preventing the synthesis of DNA halting cell growth.
Explanation:
Fluorouracil and methotraxate prevent the synthesis of the neucleoside Thymidine thus preventing DNA replication and elongation. Methotraxate has a structure analogous to Folic acid which is important for thymidine synthesis. Thus, it acts as a competitive inhibitor on dihdrofolate reductase an enzyme that is essential for tetrahydrofolate formation, a folic acid derivative.
Fluorouracil acts by inhibiting thymidylate synthase which catalyses an essential step in Thymidine synthesis.
Answer:
B
Explanation:
The equation is glucose + oxygen ==> carbon dioxide + water and energy is produced in the form of ATP.
The correct answer is A.
Muscles need energy to produce contractions. The energy is derived from ATP (which stands for adenosine triphosphate) that is present in muscle cells.
Muscles tend to contain only limited quantities of ATP. When depleted, ATP needs to be resynthesized from other sources namely creatine phosphate (CP) and muscle glycogen. Other supplies of glycogen are stored in the liver. The body is also able to resynthesize ATP from lipids, i.e. free fatty acids. Different sources of energy are used depending on intensity and duration of the workload .
Answer:
A) Using the same glass each time you get water from your sink.
Explanation:
Option B) is wasteful, as you do not need a brand new cup every time you refill your glass. And while paper will decompose, it is still harmful for the environment to cut down trees needed to make them, and produce those paper cups.
Option C) is harmful as well. If you were to refill a singular steel bottle, that would be much better, but the option says buy a new one each time you need water. This creates more waste that will end up in the landfills in the long run.
Option D) has a harmful impact on the environment because of the large amount of plastic waste it creates. Using a plastic bottle each time you are thirsty creates a large amount of plastic waste. Plastic requires many many years to fully decompose, and production is bad for the environment.
This is why option A) has the least harmful impact on the environment. Option A) says using the same glass each time you need water, which reduces the amount of waste created.
