In biology or human geography,population growth is the increase in the number of individuals in apopulation. Global human populationgrowth amounts to around 83 million annually, or 1.1% per year. The globalpopulation has grown from 1 billion in 1800 to 7.616 billion in 2018.
The term that refers to cell division in eukaryotic cells is Mitosis
<span>Archaebacteria kingdom is Unicellular, since they are single-celled organisms.</span>
Answer: A cell is defined as the smallest functional units of the body
Explanation:
These cells are grouped together to form tissues, each of which has a specialised function, example blood, muscles, bone. Different tissues are grouped together to form organs with a special function. For example heart is an organ made up of muscles tissue, connective tissue, nervous tissue and vascular tissue. These tissues work in a coordinated manner and enable the heart to carry out the broader function of pumping blood continuously.
While organs are grouped together to form systems, each of which performs a particular function that maintains the body Internal environment and contribute to the health of the individual. For example the digestive system is responsible for taking in, digesting and absorbing food which involves a number of organs, including the stomach and intestines.
Therefore the statement that 'organs are large structures that keeps us alive" is a correct claim.
For the answer to the question above, <span>Muscles can only contract, not push </span>
<span>"Muscle fiber generates tension through the action of actin and myosin cross-bridge cycling. While under tension, the muscle may lengthen, shorten or remain the same. Though the term 'contraction' implies shortening, when referring to the muscular system it means muscle fibers generating tension with the help of motor neurons (the terms twitch tension, twitch force, and fiber contraction are also used)."</span>
