Explanation:
Woody plants, such as trees, tend to have more genetic diversity, on the whole, than vascular plants, such as grasses. Part of the diversity is due to the size of each species' geographic range and how far they can move their genetic information, for example through wind pollination or animal seed dispersers
In order from least to most dense, it must be: C, B, A and D. Seawater with high temperature causes an object to float, while seawater with low temperature sinks or is denser than high temperature. Salinity is also a factor to determine density; the higher the salinity, the denser the water. In terms of depth, it seems that sample D is the deepest part while sample A is the shallowest. This is determined because temperature drops significantly with depth.
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:
Myosin molecules consist of two heavy and two light polypeptide chains. (Ans. C)
Explanation:
Myosin are present in both cells prokaryotic, and eukaryotic, it is present as a filaments inside the cells, and consist of two heavy, and two light polypeptide chains. It is function as a no. of interactions like contraction, and movements of muscles.
Myosin is known as a motor protein which helps to move the cell, and works with the globular protein, known as actin which polymerize to synthesize actin filaments. They are depends on ATP (a molecule that cells are using to work & live, into mechanical energy). Then this will generates movement, and forces.
