I HOPE THIS HELPS.....GOOD LUCK!!!
<span>Stem cells begin to transfer into different types of cells in the human body in a process known as cell </span>differentiation.
<span>Cellular differentiation occurs throughout the cell development of a multi-cellular organism. It occurs when the cell changes from a simply zygote into a complex system of tissues and cell types. </span>
<span>Stems cells are cells which have the potential to develop into many different cell types in the body during early life and growth. Stem cells serve as internal repair system in many tissues. When stem cells divide while undergoing cell differentiation, it can either retain being a stem cell or become another type of cell like muscle cell, brain cell, or red blood cell.<span>

Answer:
Mass of the aluminium chunk = 278.51 g
Explanation:
For an isolated system as given the energy lost and gains in the system will be zero therefore sum of all transfer of energy will be zero,as the temperature will also remain same
A specific heat formula is given as
Energy Change = Mass of liquid x Specific Heat Capacity x Change in temperature
Q = m×c×ΔT
Heat gain by aluminium + heat lost by copper = 0 (1)
For Aluminium:
Q =
Q = m x 17.94 joule
For Copper:
Q= 4996.53 Joule
from eq 1
m x 17.94 = 4996.53
Mass of the aluminium chunk = 278.51 g
Answer:
A
Explanation:
The amplitude of a sound wave determines its loudness or volume. A larger amplitude means a louder sound, and a smaller amplitude means a softer sound.
Given that,
Bulk modulus
Change in volume
Edge
The volume of the cube at the ocean's surface will be
Where, a = edge
Put the value into the formula
We need to calculate the change in pressure
Using formula of pressure
Put the value into the formula
The pressure increases by for every meter of depth
We need to calculate the depth
Using formula for depth
Hence, The depth is 9.75 m.
