Work is said to be done when an object moves due to a force applied. Work is calculated by multiplying the force applied and the distance traveled due to the force. It is expressed as:
W = Force x distance
W = 84 J = F (7.0 m)
F = 12 N
Hope this answers the question.
Answer:
c. Only one of the statements is true
Explanation:
Quaternary structure, the highest level of protein organization in which association of several protein chains are closely arranged. The protein subunits are attached together by van der Waals forces and hydrogen bonds between nonpolar side chains. it is present in all the proteins which have 80 or more amino acids are present.
Collagen, is most abundant protein in the animal kingdom. It is insoluble fibrous protein present in the extracellular matrix and in connective tissue.
A protein chain has directionality consist of a free amino group at one end, and a free carboxyl group on other end.
Hence, only (2) statement is true the correct option is c.
Answer:
The diameter of the xylem vessels should be small in order for the capillary action to take place.
Explanation:
The vessels through which water is transported to different parts of the plants and trees are the xylem. Water is transported in the trees through a mechanism named as capillary action. This mechanism can occur only if the diameter of the vessels are small.
The water molecules adhere to the walls of xylem and an upward force is generated. If the diameter of the vessels i.e xylem would be small then the surface tension between the xylem and water molecules would be enough to move the water in an upward direction.
