The answer would be D, as even though both velocity and speed may share similar resultants in this scenario, speed is a scalar, while velocity is a vector. Thus, velocity can have direction and move negatively (the opposite direction from which it started) while speed is a measurement of quantity.
Answer:
Option-A
Explanation:
A bacteria divides by binary fission which divides a parent bacteria into the two daughter cells and generation time refers to the average time difference between two consecutive generations.
The bacterial cell grows by the exponential function that is by 
x initial population of bacteria.
In the given question,
<u>Initial population</u>
the initial population of bacteria - 2x 10³ per ml
So per liter, the bacterial population will be 2 x 10 ⁶
<u>Generation time</u>
1 generation time of bacteria is 30 min.
so 5 hours will have- <u> </u>
= 10 generations
<u>New bacterial population</u>
Using formula<u> </u> x initial population of bacteria
x (2 x 10⁶)
= 1048 x (2 x 10⁶)
2048 x 10⁶
Thus, Option-A is the correct answer.
Muscle contraction happens only when the energy molecule called adenosine triphosphate (ATP) is present
According to the research, the correct option is uni-axial synovial joint. When considering the classification of joints based on the shape of the articulating bone ends, the knee functions as a type of synovial joint are called a <u>uni-axial synovial joint</u>.
<h3>What are uni-axial synovial joints?</h3>
They are synovial joints because they have cartilage and a joint capsule that allow flexion and extension movement, and it is because they move in a single plane or axis that they are considered monoaxial.
In this sense, they can be located in the humeroulnar joint located in the elbow, in the femorotibial or knee joint, allowing the rear sides of the leg to be moved away or closer, and finally in the joints that form between the phalanges of the fingers.
Therefore, we can conclude that according to the research, the correct option is uni-axial synovial joint. When considering the classification of joints based on the shape of the articulating bone ends, the knee functions as a type of synovial joint are called a <u>uni-axial synovial joint</u>.
