A library without books isn't a library at all same with the cells, a cell without a DNA is nothing and maybe is the absence of life.
<span>Nucleus, the control center of the cell is the organelle which intiates, enables, and manages the various simplex. compound and complex cellular activities. It also stores the DNA of the cell which is then replicated and recopied over a hundredth and thousandth times over through cell division processes. In the nucleoplasm -nucleolus, the inner part of nucleus of a cell is where the DNA to mRNA and to protein; vice-versa happens. <span>

<span>*The RNA directed synthesis of a protein. RNA makes protein-----TRANSLATION
*Nitrogenous base found only in DNA ------ THYMINE
*The DNA directed synthesis of RNA. DNA makes RNA--------TRANSCRIPTION
*Ribosomes need this to decode the message in mRNA------ tRNA
*Carries DNA's message from DNA to ribosomes.------- mRNA
*Nitrogenous base found only in RNA ---- URACIL</span>
Polar bears are animals that live in cold environments.
Their environment should be a place conducive for breeding and propagating
their species. If ice caps are melting and the length of the cold season is
declining because of the effects of climate change, polar bears will have less
time hunting for food.
Generally, the coldest season is the best hunting
time for polar bears. It is easier to catch seals and fish due to the thickness
of the ice and the rise of water in their environment. This time to hunt is
enough to restore the polar bears’ body fat and fitness in preparation for the
warm season where there is less ice and food.
<span>As the warm season lengthens, the condition of
the polar bears’ bodies decline resulting to effects that are serious for pregnant
polar bears who are nursing and cubs who need their mothers’ energies to
survive the harsh environment. </span>
B. is the correct answer :)
<span>Controlling your blood pressure. It is the anti-diuretic hormone that works in your kidneys and blood vessels. It keeps the kidney from releasing too much water into the urine. ADH is made in the hypothalamus of your brain and then stored in the back of the pituitary gland.</span>
