Answer:
C.Interia
Explanation:
Objects have a natural tendency to resist change. This is INERTIA. Heavier objects (objects with more mass) are more difficult to move and stop. Heavier objects (greater mass) resist change more than lighter objects.
Answer:
In 1962, Crick, Watson and Wilkins jointly won the Nobel Prize in Medicine for their discoveries about the structure of the DNA molecule.
Francis HC Crick was physics but in 1947 he moved to biology research when began to work at the University of Cambridge, in the field of X-ray crystallography of proteins, where obtained his PhD in 1954. Crick shared with Watson his interest in the structure of the Deoxyribonucleic acid (DNA) molecule.
In 1950, James D. Watson began to work in Copenhagen, by studying bacterial viruses. In Naples, he observed for the first time a crystalline X-ray diffraction pattern. In the next year, Luria and Kendrew helped Watson to go at the University of Cambridge. In the Cavendish Lab from this Univesity, he continued working with X-ray diffraction patterns and he met Francis Crick, who was also trying to decipher the molecular configuration of the DNA molecule.
In 1953, Crick's and Watson's could state that the DNA molecule had a double helix, twisted-ladder structure. By using their model, they also showed that the DNA could replicate itself. Also in 1953, both (Watson and Crick) published their discoveries in the prestigious Nature journal, with the famous title: "Molecular Structure of Nucleic Acids: A Structure for Deoxyribose Nucleic Acid”
Answer:
Independent variable - Player being good or bad , presence of audience
Dependent variable - Performance of player
Explanation:
Independent variables are the constant variable in an experiment whose effect is studied on the subject of the experiment. While dependent variables are those which are dependent upon the independent variable.
Here, performance of the player is independent variable which is dependent upon the presence of audience. Hence “presence of audience” is the independent variable. Also , the type of player is also an independent variable which shall effect the performance of an individual player
The population size of a predator species is directly controlled by the population size of it's prey. If the predator has no prey the population size will go down because they have no food.
This is a true statement.
Hope this helps~!
