Answer: D. downwelling
Downwelling is a oceanographic phenomena, in which the higher density material accumulates and sink below the low density water. The higher density sediments from the surface runoff sink down. The downwelling provides the supply of oxygen to the lower water layers along with the minerals present in the sediments. This allows the aerobic organisms to survive underwater. Therefore, Pedro should read the phenomena of downwelling to understand the fact that how aerobic organisms survive under water.
Answer:
C
Plants are living things but most cannot move. (Not A)
Some living things don't breathe like virus they don't go through cellular respiration. (Not B)
There are thousands of living things that are not visible to the naked eye, like water bears. (Not D)
They are related because energy cycles consist of energy and growth cycles also need energy so they can work
The connecting piece of a sperm is packed with gonads that produce energy.
Sperm is the male reproductive cell and is derived from the Greek word "Sperma" Significance is Root.
Sperm cannot divide and have limited life span, but after fusion with egg cells through fertilization, a substitute orgasm begins developing, starting as a totipotent zygote
Answer:
The 5' end has free phosphate group while the 3' end has free OH group.
Explanation:
Each DNA strand has two ends that differ from each other with respect to the functional group. The nucleotide present at the 5' end of a DNA strand has a free phosphate group. This phosphate group of other nucleotides of the DNA strand is bonded in phosphodiester bonds. Likewise, the 3' end of a DNA has a free OH group. This makes the two ends of a DNA strand quite different from each other. A DNA new nucleotide can be added to the 3' end due to the presence of a free OH group.
