Explanation:
The planet Mars has two moons. Phobos and Delmos (i) phobos has period `7` hours, `39` minutes and an orbital radius of `9.4 xx 10^(3) km`. Calculate the mass of Mars. (ii) Assume that Earth and mars move in a circular orbit around the sun, with the martian orbit being `1.52` times the orbital radius of the Earth. What is the length of the martian year in days? `(G = 6.67 xx 10^(-11) Nm^(2) kg^(-2))`
0.5. This is because if the cells have not swollen or shrunk then the water potential (and therefore amount of solute) inside and surrounding the cell must be equal.
Answer: Option C.
Cellulose.
Explanation:
Cellulose is a polysaccharide which is made up of glucose and it is an important component in plant cell wall. It give strength and rigidity to the cell wall. Cellulose make the cell walls strong. This play a regulatory role in tissues growth and provide strength. The cellulose is only found in cell wall and it's protect the cell wall.
Answer:
Work
Explanation:
Work can be referred to as the application of a force (F) over a distance (d). In other words, WORK is done when an applied force causes a body to move. Hence, work is a product of the force and the displacement in the direction of the force i.e. W = F × d
In this case, a desk is PULLED along the floor in your classroom, this best indicates WORK because a force (pull) is applied on the desk causing it to move over a distance in the direction of the pull.
