Zones in which interpersonal interactions can take place are known as proxemics
Edward Hall, a famous anthropologist coined the term ‘Proxemics. He was interested in understanding how humans use space in communication. Thus, proxemics is about the study how humans using space during their communication with others. It is about how close one stand to someone, whether one touches each other and how comfortable we feel are all part of the study of proxemics.
<span>The movement along the concentration gradients allows for the cell to maintain homeostasis. Keeping a cell in the proper conditions inside and out allows for it to function properly and carry out the duties that it is required to do as part of its bodily system.</span>
The leaves are smaller, meaning the plant cannot photosynthesize as fast as before. This means that the plant cannot produce as much energy and grows slower as a result.
<u>Answer:</u> "Chemical fossils"evidence supports the notion that sponges are some of the earliest known multicellular animals.
<u>Explanation:</u>
Sponges are multicellular animals, may belong to Ediacarian period likely to be 80 million years ago or earlier. They catered through a complex system of internal channels, by moving seawater.
Sponges are soft-bodied and very rarely protected as fossils, therefore finding evidence of existence is giant task. The key of their existence came to know from abnormal chemicals which is a steroids of a particular type generated sufficiently by them but virtually never by ordinary organisms.
Analysis of long strata sequence found in Oman and researchers have been able to extract these "chemical fossils" from samples spanning tens of millions of years — before, during and after the Ediacarian period.This gave clear evidence that sponges had to have evolved long before the great variety of multicellular organisms proliferated at the dawn of that time.
Answer:
Pyramidal decussation is at the junction of medulla and spinal cord.
Explanation:
Pyramidal decussation may be defined as the the fibers that cross the corticospinal tract from one side to the junction and the other side to the central nervous system.
Pyramidal decussation is the point at the junction between spinal cord and medulla. The motor fibers crosses the midline from the medullary pyramids.
