Describe the purpose of cell differentiation in embryonic development.
Answer:
The differentiation of cells during embryogenesis is the key to cell, tissue, organ, and organism identity. Once an egg is fertilized by a sperm, a zygote is formed. The zygote divides into multiple cells in a process known as cleavage, triggering the beginning of embryonic differentiation

In general, the probability of flooding decreases when there is an increase in the amount of
1) infiltration
2) Snow melt
3) runoff
4) precipitation
Flooding is a natural disaster that is caused due to overflowing water. The possibility of flooding decreases when there is an increase in infiltration. Thus, option 1 is correct.
What is infiltration?Infiltration is the process of Hydrology where the water on the upper layers or the ground moves and sweeps inside the soil through permeability or filtration. The soil shows the property of infiltration allowing the water to move through the different soil profiles.
The greater the infiltration property of soil the greater it will absorb the groundwater into it. This will decrease the case of flooding as no water will get deposited on the ground. It will raise the water level of the table and decreases the water pooling at the surface.
Therefore, option 1. an increase in infiltration, decreases the flooding.

What process do scientists think explains the evolution of mitochondria and chloroplasts from bacteria
Scientists put their conclusions into this by creating th Endosymbiotic theory. The endosymbiotic theory describes how mitochondria and chloroplasts (cell organelles) came to exist in eukaryotic organisms. The endosymbiotic theory explains the evolution of mitochondria and chloroplasts. Before mitochondria and chloroplasts were organelles in a cell, they were free prokaryotic cells that were absorbed by eukaryotic cells.
The mitochondrion was originally a prokaryotic cell that could undergo aerobic respiration. After being absorbed by a eukaryotic cell, it developed a symbiotic relationship with its host cell.
The chloroplast was originally a prokaryotic cell that could undergo photosynthesis (eg. cyanobacteria). Like the mitochondria, the photosynthesizing bacteria became dependent on the host cell after being engulfed.
There is much evidence to support the endosymbiotic theory.
Both prokaryotes and chloroplasts/mitochondria have circular DNABoth have their own ribosomesBoth divide through binary fission (splitting into two)Both have their own cell membranesThe magnets point North when the Earth's magnetic field has (p2)

The magnets point North when the Earth's magnetic field has?
ANSWERI think the best answer for this question is Magnetic Reversal or Geomagnetic Reversal.
In geomagnetism, the term "geomagnetic reversal" also known as 'flip', is the process by which the North pole becomes South pole and the South pole transforms into North pole.
THE MAGNETIC REVERSALThe reversals happen on rare occasions when iron molecules start moving towards the opposite direction as other iron molecules around them within the Earth's spinning outer core.

Which contributes to the greenhouse effect?
The greenhouse effect is when the Sun's light is trapped into the lower atmosphere, heating up the planet. Carbon dioxide, or co2 makes up the majority of greenhouse gas emissions. Smaller amounts of methane(ch4), and nitrous oxide(n20) are also emitted. These gases are mainly emitted through the continuous use of fossil fuels such as coal, oil, and natural gas.
