How are wastes carried to the kidney for removal? in cells
in the urine

The correct option is: c. in blood


A kidney is a bean-shaped organ, that is present below rib cage in the retroperitoneal space. In vertebrates, the kidneys are present in pair. Each kidney receives blood from the paired renal arteries. The main function of a kidney is to filter the urea present in the blood with the help of filtering units, called the nephrons.


Synovial joints are ____________ and thus allow for a variety of movements. Flexion of synovial joints ____________ joint angle while extension of synovial joints ____________ joint angle. Adduction moves body parts ____________ the midline while abduction moves them ____________ the midline. Rotation moves a body part ____________ its own axis while circumduction moves a body part such that a cone shape is outlined. Inversion turns the sole of the foot ____________ and eversion turns it ____________ .



The correct answer will be  

1. flexible

2. decreases

3. increases

4. toward

5. away

6. around

7.  inward

8. outward


he Synovial joints are the joints which allow the movement of the body parts. The type of movement is determined by its structural type in which flexion and extension motions takes place in the anterior-posterior plane. In the limbs, the flexion decreases the angle in the bones while extension increases the angle between the bones.  

The abduction- adduction motions involve the medial-lateral motions of the bones in which Abduction moves the limb away from the midline of the body while adduction moves limb toward the midline.

Circumduction is the movement of a body region in a circular manner while rotation is the movement of the body part around its own axis.

Inversion and eversion are the complex movements in which inversion is the turning of the foot toward the midline or inward movement while eversion is reverse of this.

Thus, the selected options are the correct answer.
