Answer:
d) Stratified layering
Explanation:
The wall of the ducts is formed by a lining epithelium that forms a small tube with a central lumen. The epithelium that forms the duct is initially of the simple cubic type. If the gland is small and the duct is short, it maintains this structure throughout its course, subjected to a high degree of pressure.
These ducts have from more complex glands the duct epithelium ends up becoming simple prismatic and may even become stratified. In this case, the tissues have stratified layering
The only cells that don't have jobs are either stem cells, which are to be used later, or cancer cells, which are extras.
Answer;
Sensory receptors
Sensory receptors are pecialized cells that detect stimulus information and transmit it to sensory (afferent) nerves and the brain.
Explanation;
A sensory receptor is a structure that reacts to a physical stimulus in the environment, whether internal or external. It is a sensory nerve ending that receives information and conducts a process of generating nerve impulses to be transmitted to the brain for interpretation and perception.
-Sensory receptors vary in classifications but generally initiate the same process of registering stimuli and creating nerve signals.
Answer:
Muscles connect to your skeleton and they contract and move the skeleton along.
Explanation:
Your skeletal system is made up of cartilage and calcified bone that work together. They help the process of movement happen in a smoother manner. The calcified bones of your skeleton also work with the circulatory system.
Explanation:
Pollen grains are the male gametes in plants. It is present on the anthers. Pollen grains finds its way to the ovule by the process of pollination. The structure of pollen grains vary from one species of flower to another. The hibiscus and spider lily both have circular pollen grain.
However, the atomic structure of pollen grain of hibiscus represents the Buckminster fullerene but is not shown in spider lily. The pollen grains of hibiscus have spikes on its surface.
