Answer:
Isometric contraction
Explanation:
The length of the muscle is changed during contraction only when the muscle tension during contraction can outstand the resistance exerted by the object to be lifted.
During isometric contractions, the muscle tension is not sufficient to exceed the resistance of the object. Hence, there is no change in the length of the muscle. The isometric contraction does not bring about any body movements.
Answer:
They are called Stomatas.
Explanation:
A waxy cuticle covers all aerial surfaces of land plants to minimize water loss. These leaf layers are clearly visible in the scanning electron micrograph. The numerous small bumps in the palisade parenchyma cells are chloroplasts.

Carbohydrates provide structural support, in the form of cellulose in cell walls, for plants in addition to providing energy for the organism
Proteins are essential for muscle tissue's growth and development as well as, in the form of hormones and hormonal regulation, maintaining an organism's homeostasis.
Lipids make up the bilayer of cell membranes, and also aid hormonal signaling.
Nucleic acids store genetic information, and allow for ribosomal protein synthesis.
Answer: The structure of the spinal cord can be described as consisting of all the above named.
Explanation:The spinal cord is the main pathway for information connecting the brain and peripheral nervous system. Much shorter than its protecting spinal column, the human spinal cord originates in the brainstem, passes through the foramen magnum, and continues through to the conus medullaris near the second lumbar vertebra before terminating in a fibrous extension known as the filum terminale.
It is about 45 cm (18 in) long in men and around 43 cm (17 in) in women, ovoid-shaped, and is enlarged in the cervical and lumbar regions.
Answer: The concentration of salt is high and lacks hydration.
Explanation: A cell must stay in homeostasis cellularly if the cell has shrunk its salt is too high and needs hydration.
