Answer:
Size of particle.
Explanation:
Size of the particles that are diffusing is the factors that greatly affect the rate of diffusion. The rate of diffusion decreases if the thickness of the membrane becomes doubled while on the other hand, if the surface area of the membrane increases it doubled the rate of diffusion of the cell. If the size of particles is very small so it will diffuse if the membrane has double thickness.
Answer:
F = 25000 N
Explanation:
It is given that,
Pressure exerted by the object, P = 1000 Pa
Area of cross section, A = 25 m²
We need to find the force exerted on an object. The pressure exerted by an object is equal to the force acting per unit area. So,
So, the force exerted on an object is 25000 N.
Most likely it would be more dry
Answer:
It is important that cell growth in a multi-cellular organism be regulated carefully so as to maintain the integrity of the cell cycle
Explanation: Each cell in a multi-cellular organism has it cycle which consist of the inter-phase and the m-phase (active division). Cell growth takes place in the G1 phase of the inter-phase and this ensures that deoxy ribonucleic acid is synthesized in the S-phase in preparation for division.
Hence, adequate cell volume is a key event in order for division to take place. If cell growth is not regulated, it might result in a cell exiting the cell cycle into the resting phase in case of slow growth or result in over-division of a cell in case of over-stimulated growth. The latter is often the case in the development of cancerous cells.
All eukaryotic organisms have cells with a nucleus surrounded my a membrane.
