Answer:
In intravenous ossification, bone develops directly from sheets of mesenchymal connective tissue. In endochondral ossification, bone develops by replacing hyaline cartilage. Activity in the epiphyseal plate enables bones to grow in length. Modeling allows bones to grow in diameter.
Explanation:
All organisms are composed of one or more cells
Cells are the basic unit of structure and function in a living organism
Cells come only from the reproduction of existing cells
Answer:
The answer is scientific method.
Explanation:
The Scientific Method:
The Scientific Method is the standard process of experimentation and inquiry used to test hypothesis and answer scientific questions.
Every scientific question requires a specific form of the scientific method, with the variations ranging from the scope of the hypothesis to the experimental design and data analysis methods.
The steps of the scientific method are as follows:
1. Observation/Question
2. Hypothesis
3. Experimentation
4. Data analysis
5. Conclusion
The conclusion includes analysing the results and developing further hypotheses and testing them. If the hypothesis remains irrefutable, it becomes a theory. If the theory remains irrefutable after rigorous experimentation in various studies by multiple scientists, the theory becomes a law.
Answer:
t = ln (N/N°)/(-0.0239)
Explanation :
The decay law is represented as
N = N°e^-kt
Where N is the final number of atom,
N° is the initial number of atoms
k is the decay constant
t is the half-life.
From the above we have,
N/N° = e^-kt
take ln of both sides
ln (N/N°) = -kt
t = ln(N/N°)/-k
At half life, N/N° = 1/2
Therefore, t = (ln 1/2)/-k
t = -0.693/-k
But t = 29 sec
29 = -0.693/-k
k = 0.0239 s^-1
Therefore,
The formula will be
t = ln (N/N°)/(-0.0239)
Answer:
Yes. Due to the magma in the mantle, the tectonic plates in the upper crust of the earth move because of a process called *convection. The heat from the magma causes the tectonic plates to move at a very very slow rate
*An example of this is when you're cooking food in a pan. The food is getting hotter because the heat rising from the stove heats the pan.
In simpler terms: Stove ~~ Pan --> hot food
*There is no direct contact between the stove and the pan which is a defining feature of convection.
