When bone marrow cells go through the cell cycle, the two identical daughter cells that result form mitosis have very different functions. Following g1, one daughter cell leaves the cell cycle and becomes a specialized blood cell. The second marrow cell remains in the marrow as a stem cell and repeats the cell cycle. What molecule is responsible for determining the fate of each cell?
Answer:
The cell-intrinsic properties arise from a cleavage of a cell with asymmetrically expressed maternal cytoplasmic determinants (proteins, small regulatory RNAs and mRNA). Thus, the fate of the cell depends on factors secreted into its cytoplasm during cleavage.

Why is ATP so useful for cellular energy
Answer: ATP is useful because it gives energy to make things and for cellular process
Explanation:
ATP is the main source of energy for most cellular processes. When energy is not needed by the organism, the phosphate group is added back to AMP and ADP to form ATP - this can be hydrolyzed later as per required. Thus, ATP functions as a reliable energy source for cellular pathways.

Q16.A needle can be made to "float" on the surface tension of water. What causes this surface tension to form?
Select one:
a. The ability of water to regulate temperature
b. The cohesion of water molecules to each other
c. The ability of water to act as a solvent
d. None of the above X
Answer:
B
Explanation:
Water has surface tension due to cohesion that allows it to 'stick' together. This cohesion is created by the fact that water is polar and has unequal distribution of charges. The oxygen becomes slightly negative as it is surrounded by positive hydrogen. In turn, the hyrdogen becomes slightly positive.
This means that the hydrogen molecule is temporarily attracted to the oxygen of another molecule. This causes surface tension and allows light objects to float on top of it

1) Why is having no leaves a good adaptation for plants found in the desert?
2) What is the evolutionary significance of developing pouches? (What makes a pouch a good adaptation?)
Answer:
1)The leaves and stems of many desert plants have a thick, waxy covering. This waxy substance does not cover the stomata, but it covers most of the leaves, keeping the plants cooler and reducing evaporative loss. Small leaves on desert plants also help reduce moisture loss during transpiration.
The row of energy in a grassland ecosystem is shown
Hognose snake
Owl
Toad
Spider
Rabbit
Sparrow
Cricket
Grass
Mouse
Based on the diagram, which two populations best represent trophic levels that receive the
LEAST amount of the total energy provided to the ecosystem by the grass?
A Crickets and sparrows
B
Toads and spiders
C Rabbits and mice
D
Hognose snakes and owls
The populations with the trophic levels that receive the least amount of the total energy from the grass would be Hognose snakes and owls.
Trophic LevelThe higher we move up a trophic level, the lower the amount of energy transferred from the previous levels.
More precisely put, only about 10% of the total energy available at one trophic level is transferred to the next while the rest is lost as heat to the surrounding.
In this case, Hognose snakes and owls represent the two highest trophic levels in the ecosystem. Thus, their populations would receive the lowest amount of energy from the producer, the grass.

Wastes from miningMining is a process used by geologist to extract valuable minerals that are naturally deposited within the earth.
Example of such minerals are:
metals and coal, oil shale and gemstones, limestone and chalk, rock salt, potash, gravel, and clay.While mining processes are carried out, it leads to the generation of waste products such as:
ferrous and nonferrous metal ores, sulfur ores, apatite-nepheline concentrates, coal wastes and halite flotation wastes.These mining wastes can leak into the nearby ponds after a heavy down pour leading to the contamination of the ponds.
