Investigators should keep in mind that eyewitness identification is highly infallible. true, since the law takes the identification as a positive test and completely commits those involved and an error in it could tarnish the course of justice and consequently of the investigators.
Answer:
Lamarckism, a theory of evolution based on the principle that physical changes in organisms during their lifetime—such as greater development of an organ or a part through increased use—could be transmitted to their offspring.
Explanation:
The classic example used to explain the concept of use and disuse is the elongated neck of the giraffe. According to Lamarck's theory, a given giraffe could, over a lifetime of straining to reach high branches, develop an elongated neck.Although the name "Lamarck" is now associated with a discredited view of evolution, the French biologist's notion that organisms inherit the traits acquired during their parents' lifetime had common sense on its side. ... According to Lamarck, organisms altered their behavior in response to environmental change.
Sunlight is the original source of almost all energy in most ecosystem.
Answer:
During Prophase 1 the crossing over of the homologous pairs of chromosomes exchange parts of each other which can result causing new traits.
During independent assortment chromosome pairs align randomly during metaphase I which also creates diversity.
Random Fertilization makes up genetic diversity because of the mixture of each unique sperm with each individual egg.
Explanation:
Answer:
C- it help to show that some bacteria are just one cell.
Explanation:
Anton Leeuwenhoek was the first scientist who observed the presence of bacteria in his tooth scratch under the microscope made by himself. At that time there was no concept of bacteria and he named those small creatures as animalcules which were later termed as bacteria.
Leeuwenhoek during 1670s sent the details of his experimentation on algae and bacteria to Royal Society of London.
It was due to his that primitive experiment that made the discovery of bacteria and make it known to other scientists. Therefore option C is the best option that demonstrates that bacteria are single celled organisms that are very minute. When we look at cell theory there is a postulate that shows that cell is the fundamental unit of function and structure of all living organisms. So, the work of Anton Leeuwenhoek holds substantial importance in the formulation of cell theory.
