Answer:
TRUE
Explanation:
S phase (Synthesis Phase) is the phase of the cell cycle in which DNA is replicated, occurring between G1 phase and G2 phase. Since accurate duplication of the genome is critical to successful cell division, the processes that occur during S-phase are tightly regulated and widely conserved.
"The organisms found in the shady area beneath a tree will be different from those found in the rain puddle" statement is most likely true regarding the organisms found in these two microhabitats.
<u>Option: B</u>
<u>Explanation:</u>
The narrow-scale environmental conditions of a specific entity or an organism population is understood as microhabitat. With relation to given statement, birds who protect themselves from getting wet because it become barrier for them to fly high and search food, at the same time the worms and snakes kind organisms enjoy rainy season by coming out from their holes, because they find difficulties in surviving outside their shady area during humid or summer season. Each habitat contains numerous microhabitats with subtle differences in exposure to light, humidity, temperature, circulation of air, and many other considerations.
The fluid-mosaic model describes the plasma membrane of
animal cells. The plasma membrane that surrounds these cells has two
layers (a bilayer) of phospholipids (fats with phosphorous
attached), which at body temperature are like vegetable oil (fluid).
And the structure of the plasma membrane supports the old saying, “Oil
and water don’t mix.”
Each phospholipid molecule has a head that is attracted to water (hydrophilic: hydro = water; philic = loving) and a tail that repels water (hydrophobic: hydro = water; phobic
= fearing). Both layers of the plasma membrane have the hydrophilic
heads pointing toward the outside; the hydrophobic tails form the inside
of the bilayer.
Because cells reside in a watery solution (extracellular
fluid), and they contain a watery solution inside of them (cytoplasm),
the plasma membrane forms a circle around each cell so that the
water-loving heads are in contact with the fluid, and the water-fearing
tails are protected on the inside.
