Cellular differentiation starts right after pituitary development.
The 2 organelles that contain their own DNA are the chloroplast and mitochondria
Answer:
slab push, volcanic eruptions, and subduction
Explanation:
To understand better, let's consider an example. Make small pieces of paper and put them in a bowl containing water. Then heat the bowl. After sometime, you will see that the pieces are moving. This is because of same phenomenon (convection currents) forming inside the bowl of water. The water will warm move upward whereas colder water will come to its place. Convection currents in Earth are formed due to high temperature of magma (molten rock material) that rises up and colder magma takes its position.
This process results in slab push, volcanic eruptions, and subduction.
<u>Slab pull</u>: Slab pull is the force exerted by plates during subduction. Subduction is a process when a denser plate moves beneath the less denser plate. Thus slab pull is also caused by convenction currents.
<u>Volcanic eruption</u>: During subduction, denser plate moves beneath the less denser plate until it reaches magma. There, the lithosphere destroyes. On a weaker lithosphere zone, the magma moves upward and break the crust thus leading to volcanic eruptions.
<u>Subduction</u>: As mentioned above, during subduction, denser plate moves beneath the less denser plate which is driven by convectin currents.
<h3><u>Answer;</u></h3>
Potassium-40 has a half life of 1.25 billion years.
<h3><u>Explanation;</u></h3>
New amount = Original amount × (1/2)^n ; where n is the number of half lives.
Original amount is 50 atoms
New amount is 25 atoms
Therefore;
25 = 50 × (1/2)^n
1/2 = (1/2)^n
Thus; n = 1
n = 1 which is equivalent to 1.25 billion years
Therefore;
<u>Potassium-40 has a half life of 1.25 billion years.</u>
Answer:
There is only 1 answer
Explanation:
A. Sandy soil will be able to!
B: Yes it is possible for loess to occur but its pretty rare
C. Deep and rich soils are soils that are soaked with water and uses thick substances so no
D. Soils that are not prone to erosion so they can but in some cases they could erose
but loess is caused by a soil that was produced by rocks and sometimes when they grind and break down they turn into soil such as sandy, clay and even loamy sand brushed over by wind
Like such as a man made grand canyon is made of loamy sand soil that is absorbed by the rocks by rain water and soil turning the rocks into grand canyons
by best bet is sandy soil, particles deposited by water.
