When half of the earth is facing the sun we have daylight.
<u>Explanation:</u>
The earth rotates about its in every 24 hours. When the earth's one of the sides faces the sun, then days occurs. When the side of the earth is far away from the sun, then night occurs. The earth rotates in an anticlockwise direction when we view form the north pole. The daylight sweeps the darkness from east direction to that of the west across the world.
All planes have day and night times because they all rotate about their axis. The day and night cycle time or the length differs for each planet. this is because the speed in which they rotate differs. The planet mars has the same day and night cycle length as earth.
A large cloud of gas (hydrogen) and dust a nebula begins to collapse
The collapsing cloud begins to spin
The spinning collapsing cloud flattens into a rotating disk
Material in the disk begins to accumulate in the center
As the material coalesces in center, it becomes dense, compresses, and heats up.
More and more material coalesces to form a protostar.
The protostar continuse to accomulate material from the surronding disk and grow.
Eventually, the protostar becomes massive enough, dense enough and hot enough to cause the process of nuclear fusion to begin.
Nuclear Fussion isotops of hydrogen atoms (deuterium, tritium) combine to form helium atoms, energy, and subatomic particles.
Once nuclear fusion begins the protostar's “ignition” to nuclear fusion creates a solar wind that drives remaining gas and dust to the outer parts of the disk.
Then the young star stops accumulating material.
Answer:
It is significantly easier to be infected with cutaneous anthrax as compared to other forms of anthrax.
Explanation:
LD50 is the lethal dose that can cause adverse effects and death. The LD50 of cutaneous anthrax is too low as compared to inhalation and gastrointestinal anthrax which means that only few Bacillus anthracis endospores can cause infection via cutaneous route while other routes require at least 200 times greater quantity to cause infection.
This is a di-hybrid problem. When doing a punnet square for di-hybrid problems, I would suggest using the F.O.I.L method to determine how to place the alleles.
Since both individuals are heterozygous, they will be both PpLl x PpLl.
By doing the punnet square, I get the answer of D.
