Matter is anything that has mass and occupies space. There are three different states of matter- solid, liquid, and gas.
Explanation:
(3) active transport
The molecules would be moving against their concentration gradient from a region of low concentration to a region of high concentration.
While cells facilitate the transport of molecules via movement across the cell membrane, there many different mechanisms. These include passive diffusion, facilitated diffusion, and passive transport. However some very large molecules require specialized type of active transport, which requires energy in the form of ATP, in order to move substances across the membrane against their concentration gradient.
Active transport is a mediated process that requires an energy input and the use of specialized membrane proteins to move against the concentration gradient. These proteins require energy in the form of adenosine triphosphate or ATP in order to facilitate necessary conformational changes to the large protein molecules to alter the spatial location of the molecule. For instance, with Na+, K+ pumps in cell membranes.

Answer:
solid: Has a definite shape and volume. liquid: Has a definite volume, but take the shape of the container. gas: Has no definite shape or volume. change of state: When matter is converted from one of the three states (example: solid, liquid, or gas) to another state.
Explanation:
Answer:
Lambdoid suture
Explanation:
The parietal bones are two bones, located above the temporal, behind the frontal and in front of the occipital. The occipital is an odd bone of the skull, with important cranial joints and sutures. The lambdoid suture extends through the back of the head. Each parietal bone joins the occipital bone in the lambdoid suture, that is, the lambdoid suture is the joint in the back of the skull that connects the parietal bones with the occipital bone.
The respiratory system contains the lungs, so the answer is C. Hope this helps.
