Answer:
The answer is D
Explanation:
As the cell is mostly dependant on ingested materials so this will help the cell to grow and perform other important activities in the cell
Answer:
DNA:
Dexoyribonucleic acid is the genetic material of almost all the organisms except some virus. DNA contains deoxyribose sugar that lacks 2'OH group on second carbon. The nitrogenous base pair of DNA are adenine, guanine, thymine and cytosine. DNA cannot acts as an enzyme.
RNA:
Ribonucleic acid is present as genetic material in few viruses only. RNA contains oxyribose sugar that has 2'OH group at second position. The nitrogenous base pair of RNA are adenine, guanine, uracil and cytosine. RNA can acts as any enzyme in biological reactions.
The both decrease genetic variation
Answer:
Explanation:
Integral membrane proteins are permanently embedded within the plasma membrane. They have a range of important functions. Such functions include channeling or transporting molecules across the membrane. Other integral proteins act as cell receptors
Integral membrane proteins reside within the bilayer membranes that surround cells and organelles, playing critical roles in movement of molecules across them and the transduction of energy and signal
No,not all organs are weighed on a triple beam balance.
<u>Explanation:</u>
- Usually smaller sized organs like adrenals, thyroid are commonly used to be weighed on triple beam balance, whereas larger organs like lungs, liver and heart can only be weighed on grocer's scale.
- Only weight of the smaller body organs can be measured very precisely with the help of triple beam balance, where as if we measure the weight of the larger organs using the same triple beam balance,then the resultant value thus obtained will not be accurate enough.
- Hence organs are weighed on a triple beam balance.
