THe answer tothis question is in vitro fertilization in which a giant needle is used impregnate the women. <span />
One disadvantage of having a large surface area to volume ratio is the heat loss. An organism that has larger surface area has high rate heat gain and heat loss. Therefore they need to eat or acquire nutrients faster in order to sustain life.

Extremophiles are a relatively small group of bacteria that thrive in extreme conditions. An example is Picrophilus torridus
Pathogenic bacteria are the bacteria which cause diseases.

The spherical shape Bacteria is called cocci , the rod shape bacteria is called bacilli and the spiral shape bacteria is called spirilla
Answer:
Chlorophyll is a green pigment found in chloroplast in plants. It absorbs sunlight during the process of photosynthesis. It is a chelate molecule. In a chelate molecule a central metal ion forms bonds with a large organic molecule made of carbon, hydrogen and other elements like nitrogen or oxygen.
In chlorophyll, magnesium is the central metal ion and it is bonded to a large organic molecule called as porphyrin. Porphyrin constitutes four nitrogen atoms to which the central magnesium is bonded in square planar arrangement. Since chlorophyll is responsible for the green color of the leaves, more the green color more the chlorophyll content and more is the nitrogen content. Hence, chlorophyll meter measures this green light and finds out if the plant needs more or less nitrogen.
