In the first image, those are fake ribs that are attached to the sternum through the costal cartilage
in the second image are real ribs since they are directly attached to the sternum
Answer:
The correct answer would be = t = 2.112 billion years
Explanation:
Given:
The number of crystal of uranium = 275 billion
The number of crystal of lead = 1925 billion
The half-life for 235U = 704 million years
Formula using :
N = N0e−λt
where,
no. of daughter atoms = N
at time t= 0, No. of parent atoms = N0.
Time = T
Half life = 0.693/λ
Decay constant = λ
Solution:
by putting value in the formula of the half-life
λ = 0.693/0.704
λ = 0.9844
Now, putting value in the formula for the age of granite.
275 = (275+1925)e^-0.9844 t
1/8= e^-0.9844 t
e^0.9844 t = 8
taking log
0.9844t = 2.07944
t = 2.112 billion years
Answer: A group of cells that have the same function is called a tissue.
A group of tissues that have the same function is called an organ.
A group of organs that have the same functions is called an organ system

Answer:
Algae
Explanation:
Algae absorbs energy from the sun which is then transferred to the krill that eat the algae, then the herring that eats the krill and so on
