Answer:
To eat good food and other stuff
Answer:
Infancy-muscular and nervous system develop dramatically. Weight triples by end of this stage
early childhood- physical development is slower than in infancy weight also slows only doubles. mental developments advances rapidly.
late childhood- weight is slow but steady gains 5-7 pounds. gains childhood independence and more distinct personality.
adolescence- sudden growth spurt causes rapid gain in growth and height. increase in knowledge and sharpening in skills.
early adulthood- muscles are developed and strong and motor coordination is at its peak. involves moving away from peer group. and tend to be with people with same interest.
middle adulthood- mentally ability can continue to increase. can be a period of contentment and satisfaction.
late adulthood-physical development is on the decline. retirement can lead to to a loss of self esteem.
Explanation:
The three-domain system is a biological classification introduced by Carl Woese et al.in 1977[1][2] that divides cellular life forms into archaea, bacteria, and eukaryote domains. In particular, it emphasizes the separation of prokaryotes into two groups, originally called Eubacteria (now Bacteria) and Archaebacteria(now Archaea). Woese argued that, on the basis of differences in 16S rRNA genes, these two groups and the eukaryotes each arose separately from an ancestor with poorly developed genetic machinery, often called a progenote. To reflect these primary lines of descent, he treated each as a domain, divided into several different kingdoms. Woese initially used the term "kingdom" to refer to the three primary phylogenic groupings, and this nomenclature was widely used until the term "domain" was adopted in 1990.[2]
Parts of the three-domain theory have been challenged by scientists such as Radhey Gupta, who argues that the primary division within prokaryotes should be between those surrounded by a single membrane, and those with two membranes.
No they do not. Even if they did, they live in water so. Hope this helps!
