Answer:
C - Contains the embryonic disk
Explanation:
After an egg is fertilized, it begins to divide into smaller cells, from the 1 cell stage, to 2, to 4 and so on. Then, on the third day, the cells fall within 16-200 cells and it is then called a <em>morula</em>.
On the fifth day, the morula becomes a ball of calls which is now differentiated into an <em>inner cell mass and a trophectoderm</em>. The inner cell mass becomes the <em>embryo</em> as development goes on and the trophectoderm, becomes the <em>placenta</em>.
As development goes on further, the floor of the amniotic cavity is formed by the embryonic disk, a layer of prismatic cells derived from the inner cell mass.
The embryonic disc develops into 3 layers:
There is a major differentiation of cells which gives a template for the origin of development of specific organs of the embryo.
The answer should be D, because there is no motion involved. Unless, of course, you are heavier than a large cargo crate.
Work is expressed in Joules, which are Newtons times meters. Meters are a unit of distance, so if the force (in Newtons) is not producing any distance, there is no work.

Answer:
96558.00 kilometers
Explanation:
<em>From the title of the novel, it is assumed that the submarine covered 20,00 leagues on its journey.</em>
1 league = 3 miles, therefore;
20,000 leagues = 20,000 x 3 = 60,000 miles.
1 mile = 1.6093 km
Hence,
60,000 miles = 60,000 x 1.6093 km
= 96,558 km
= 96558.00 km to the 100's place
Therefore, 96558.00 kilometers was covered by Nautilus during the journey.
Answer:
any energy which is remaining in a dead organism is consumed by decomposer.
Nutrient can be cycled through an ecosystem but energy is simply lost over .
that is a point.
