Cephalization is the differentiation of end part of the body into a head in which nerve tissue is concentrated. Sponges have a very loose nervous system and their cells work individually, not controlled by a nervous system. Since they have no defined head as a consequence of concentrated nervous system, the sponges could not have cephalization either.
The area of the brain located in the parietal lobe, responsible for processing information from sensory receptors on the skin is the <u>somatosensory cortex</u>.
<h3>What is somatosensory cortex?</h3>
It is that brain area responsible for processing and treating information of a sensory nature that comes from the skin, muscles and joints.
<h3>Characteristics of somatosensory cortex</h3>
- It receives and interprets all the information that comes from the tactile system.
- Sensations of pain, temperature, pressure, as well as the ability to perceive the size, texture, and shape of objects are perceived by this section of the cerebral cortex.
Therefore, we can conclude that the sensory receptors receive information from the outside regarding touch, pain and temperature and transmit it to the somatosensory cortex.

When the cells undergo late apoptosis, the membrane structure is destroyed and the nuclear structure can be selectively visualized by Hoechst 33342/PI.

Answer:
4
Explanation:
Carbon has four valence electrons, so it can achieve a full outer energy level by forming four covalent bonds. When it bonds only with hydrogen, it forms compounds called hydrocarbons. Carbon can form single, double, or triple covalent bonds with other carbon atoms.
