Answer:
Epithelial
Explanation:
Epithelial tissues are the tissue that covers the body surfaces and line the body cavities. The cells of this tissue form a continuous sheet and are arranged in single or multiple layers. These cells are closely packed and there is little or no intercellular space. Epithelial tissue covers and lines various surfaces. For example, the body surface is covered with skin which is made up of epithelial tissue. The function of epithelial tissue is to protect the underlying parts, secrete mucus, hormones, and enzymes and to absorb and excrete substances.
Answer:
Active Transport
Explanation:
Active transport is the process of transport of substances from region of their lower to that of higher concentration. Since the transport occurs against the concentration gradient, it is energy requiring process and needs input of energy to occur.
In given example, liver cells transports vitamins against the concentration gradient in energy dependent manner. Therefore, it is an example of "active transport".
Answer:
The observation that could be made in regards a neon light placed in one evacuated (airless) chambea r, and battery powered radio placed in a second evacuated chamber, switched on at the same time by remote control, is that they are managed as capacitors.
Explanation:
Capacitors, also known as condensers, store energy and, we can also see them in the sky, they are the clouds.
Capacitors are made of two electrical conductors, separated by an insulator, when you add electrical energy to a capacitor you are charging a capacitor, the opposite is known as discharging.
Naturally ocurring, solid,inorganic, Crystal shape, and definite chemical composition.
Answer:
A and D i think
Oxygen is ONLY released and others are taken in.
Gas exchange during respiration occurs primarily through diffusion. Diffusion is a process in which transport is driven by a concentration gradient. Gas molecules move from a region of high concentration to a region of low concentration.
