Cross section of different areas of the same plant show cells with very different structure. What does this tell you about the d
BaLLatris [955]

Explanation:

-these are likely different tissue systems or organs

-they each may execute different specified functions

Cells sharing a similar origin, group together in the body to 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:

These tissues form systems that may be

  • meristematic- temporary, found at growth regions called meristems; they are undifferentiated or incompletely differentiated and continuously undergo growth and division
  • non meristematic- permanent tissue, already differentiated and are made up of plant tissue that no longer divides

Meristems differentiate into three main plant tissue types, which make up several  tissues in various amounts:

  • ground
  • dermal
  • vascular tissues

Secondary tissue types are either complex, made up of several different call types, or simple, made up of the same cell type.  Dermal tissue covers the plant's outermost layer, and mediates gaseous exchange. While two types of complex vascular tissue, are the xylem and phloem.

Xylem vessel elements: mature xylem vessel is made up of dead cells called vessel elements aligned end-to-end where these ends have been dissolved and the protoplasm is absent. These form long, continuous tubes that facilitate the unobstructed flow of water and minerals to other areas within the plant.

Describe the five categories of the vertebral column.
gladu [14]

Answer:

The five categories of vertebral column are:

  1. Cervical
  2. Thoracic
  3. Lumbar
  4. sacrum
  5. coccyx.

Explanation:

The 26 vertebrae of the spine or vertebral column are classified into five categories based on the structural differences between them. The first category is cervical and is made of seven cervical vertebrae. The spines of cervical vertebrae are shorter than that of others and have bifurcations.  

The next category is the thoracic and is made of twelve thoracic vertebrae. Thoracic vertebrae are followed by lumbar region made up of 5 lumbar vertebrae. Spines of thoracic vertebrae are longer and are directed downwards while that of the lumbar vertebrae project towards the posterior region. the sacrum is present below the lumbar region and consists of five fused sacral vertebrae. The last category of spine is coccyx. It has four fused coccygeal vertebrae.

The answers are A. life changes over time and B. Vesitigial organisms once had a function in ancient times.The trilobites first appeared in the Cambrian period and though they entered a decline int the Devonian period, some of them survived until Permian time or for a period of 270 million years. They were divided into 3 segments and were early examples of arthropods. They tended to live on or near the bottom of the oceans and were scavengers in part and as well as living on the ocean floor some swam and fed on plankton. </span>
