Answer: Two membranes contain and protect the inner parts of the chloroplast. They are appropriately named the outer and inner membranes. The inner membrane surrounds the stroma and the grana (stacks of thylakoids). One thylakoid stack is called a granum.
Explanation:
The Nervous system of the body consists of all the nerve cells. It is the body's "speedy" electrochemical communication system.
every neuron (nerve cell) has a long process known as 'axon' which is used to contact the next cell in the circuit. The receiving cell (another neuron) has small processes called 'dendrites' which are contacted by the axon. Now the neurons, like all other cells in the body, are enclosed by a selectively permeable cell membrane - which means it allows certain chemicals to pass through, while others are prevented from entering or leaving the cell
During aerobraking, the spacecraft used friction from the Martian atmosphere to slow down and to trim its initial 35-hour, elliptical orbit around the red planet to a two-hour, near-circular orbit. The final orbit was more suitable for science operations and ideal for making highly detailed observations of the surface
Answer:
5732 years
Explanation:
Radioactive decay can be determined by using the equation:
where;
= number of decayed atoms at time (t)
= initial number of decayed atoms
= decay constant
So, if we equate the natural log of the above; we have:
where;
= 
= 
= 
t = 5732.01 years
t = 5732 years.
Hence, the fossil is 5732 years old.
Answer:
i think it is chloroplasts but i am not 100% sure i am 99.99% sure tho
