Andrews [41]

Answer:

Skin has three layers: The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.

The skin has three main functions: Protection; Thermoregulation; Sensation.

The skin acts as a protective barrier from:

Mechanical, thermal and other physical injury;

Harmful agents;

Excessive loss of moisture and protein;

Harmful effects of UV radiation.

Which adds evidence to the idea that the cell is the basic unit of life

Natalka [10]

Explanation:

<em>Complete question:</em>

<em>A. Cells contain ribosomes and have a cell membrane. </em>

<em>B. It is impossible for a multicellular organism to survive. </em>

<em>C. Many organisms in the world are made of only one cell. </em>

<em>D. Small organisms are generated spontaneously. </em>

<u />

<u>Correct: C. Many organisms in the world are made of only one cell. </u>

<u />

Biology's unifying principle states that cells are the basic units of biological organisms. Cells sharing a similar origin, group together inmulticellular organismsto form tissues; these typically share physical features and are arranged in regular patterns. All living things, grow, respire, reproduce etc. these processes are carried out by cells, which are thus integral to their survival.

Further Explanation:

Before the discovery of cells by Robert Hooke in 1665 with a simple microscope, many scientists had long believed that life of rose spontaneously over extended periods of time. Circa 1668 Francesco Redi, challenged the idea of spontaneous generation of maggots from rotting meat by placing meat in various sealed open, partially sealed and sealed containers

. Sealed containers did not show the presence of maggots, and he theorized that these were likely from eggs laid on the meat by flies. This was the development of the theory of abiogenesis (cells arise from other living cells); this eventually proved the unifying principle we know today.

The advantageous proteins that build larger molecules help prolong life life. If there is better survival and reproduction, it is more likely to pass onto the next generation. If it continues to be advantageous, the sequence of them change to support the life of the current species.

The ear functions because of?

skelet666 [1.2K]

The Auricle or Pinna is the visible curvy part which trap sound to be received into the ear canal which is a passage way for sound until it reaches the ear drum which is a piece of tightly stretched skin and the end of the ear canal. The sound waves vibrate the skin which moves the stirrup, anvil and hammer or altogether known as the ossicles. The ossicles' movement the cochlea which has many tiny hairs. Nerves in the hairs pick up the movement which then gets turned into electrical pulses and sent up through the brain via the auditory nerve to be interpreted.
