Answer:
The Plants and animals all on the surface of the Earth. Disintegrate into the ground. That is A human related proble.
Explanation:
Any process that happened on Earth such as plate tonics weathering and the breakdown of rocks into smaller particles.
living things need non living things to survive. Without food, water, and air, living things die. ... Plants use water from the soil, carbon dioxide from the air, and energy from sunlight to make their own food.
Answer:
24555 years
Explanation:
Data provided in the question:
Half life of carbon 14 = 5700 years
carbon present in the dead man = 5% of the original amount of carbon 14
Now,
let the initial Amount of carbon be 'A'
Therefore,
after half life
Amount of carbon = 
Thus,
= 
here,
k is the decay constant
t is the time = 5700 years
therefore,
1 = 
or
0.5 = 
taking natural log both the sides
-0.69314 = 5700k
or
k = - 0.000122
therefore,
for dead man Amount of carbon = 5% of A = 0.05A
thus,
0.05A = 
or
0.05 = 
taking natural log both the sides
we get
-2.995 = - 0.000122 × t
or
t = 24555.18 ≈ 24555 years
Allergylymphatic disorder is characterized by hypersensitivity to a foreign antigen
Answer:
Hello!
7. A totipotent stem cell is a cell capable of differentiating into any cell required by the body.
A pluripotent stem cell can differentiate into any body cell but it is not required for the growth and development of the embryo.
Multipotent stem cells can differentiate into any cell in a specific cell lineage. For example, a red blood cell or white blood cell.
An oligopotent stem cell can differentiate into one of a specific cell type.
A unipotent cell is fully differentiated and specialized and can only produce more of its own cell type.
5. True. Tissues are a group of cells with the same structure and function.
Explanation:
Stem Cells:
A stem cell is an undifferentiated cell that has the capacity to differentiate into any cell of the body under specific conditions.
- Totipotent stem cells are the first embryonic cells produced by the division of the zygote. They can differentiate into any cell required for development.
- The embryonic cells formed through the division of the zygote are pluripotent cells.
