Leone Lattes devised a technique for determining the blood group of a dried bloodstain, which he applied to criminal investigations.
An easy technique for identifying the blood type of a dried bloodstain was invented in 1915 by the Italian scientist Leone Lattes.
In 1939–1940, the Rh blood group system—which divides blood into groups depending on whether the Rh antigen is present or not—was created. Since then, more than a hundred various blood factors have been identified.
These characteristics can be utilized to pinpoint the particular groups to which possible suspects may belong because they show up unevenly in the population.
As different blood factors are identified in a sample, the proportion of individuals who have that particular combination of factors decreases and the sample becomes more unique.

Answer: <u>Genetic Modification of crop plants.</u>
Explanation:
Genetic modification alters the genome of an organisms through the use of biotechnological tools and advancements in molecular biology. Usually, DNA is swapped among organisms, and between species; this is called transgenes. These altered plants are usually called transgenic organisms.
Some plants can be modified in several ways to meet global food security needs. These include:
-drought tolerance-plants grow in arid conditions with minimal water
-increased yield- plants produce more crop per input
I have a lot... But, I'll give two like you wanted.
1. They all need blood so that they can stay alive and keep you breathing
2. There's mucus somewhere around the lungs of all living things...

Answer:
A. Each organism had a different parent that passed on a set of unique genetic instructions.
Explanation:
Organisms can either be single-celled or multicellular. According to this question, a student collects a sample of water from a pond near her home. She then examines a drop of the water under a microscope and noticed it contains four very differently shaped single-celled organisms.
The single-celled organisms are of different shapes because they are from different parents, which passed on a set of unique genetic instructions via their genes to them. Organisms of the same species from the same parent will possess the same shape because they contain same gene which makes them look and behave similar.
However, in this case, the four different shaped single-celled organisms are of DIFFERENT SPECIES and hence, contain individual unique genes that makes them so
