Answer:
Phagocytosis is a type of endocytosis performed by phacytes. Bacteria is engulfed through phagocytosis (part of the cell membrane surrounds the bacteria inside the cell). Then lysosomes fuse with the phagosome and the bacteria is digested. After digestion, the cell perform exocytosis of waste products.
'All living organisms are composed of cells.' This is the part of the cell theory which is supported by the given pictures.
Explanation:
The cell theory were proposed by three scientists; T. Schwann, M.J. Scheleiden and Rudolf Virchow.
The cell theory states :
- Cells are basic structural and functional unit of life.
- New cells arise from pre-existing cells.
- All living organisms are made up of cells.
The given pictures are of different unicellular and multi-cellular organisms.
First picture shows a unicellular prokaryote and all the others show a section of tissue which is made up of number of cells.
On observing the pictures we can get the idea that all living organisms are composed of one or more cell.
So we can conclude, the picture supports the fact that' All living organisms are made up of cells.'

Nature vs Nurture debate.
Explanation:
Development in human is inborn.The stages of development is dictated and directed by expression of genes encoded by the DNA.Therefore physiological and biochemical interpretations of these DNA dictates is known as human development. it is a fixed mechanisms which is fastest at childhood,and progressively slower at advanced stage.<u>Although environmental factors may influence this developmental stages, the exact mechanism of occurrence is constant and fixed.</u>
<u />
Nuture concept believe that, human development is as a result of societal and cultural factors in the environment, and the progression of the development is due to the influences of theses factors on human perception of life. Thus Human development is acquired through life exposure and experiences.They are therefore dynamic, and not static, but fluctuates based on level of exposure in the environment.
<u>However, both concept interacts with one another to ensure an holistic human development. Generally it is the interaction of the environment with genetic that explains the concept of natural selection and evolution of human race. </u>
Answer:
Por medio de las hojas, las plantas realizan la fotosíntesis, respiran y producen los alimentos. La respiración se produce durante el día y la noche; para ello, las plantas toman el oxígeno del aire y desprenden dióxido de carbono.
