A. A marine biologist measures the lengths of the dorsal fins of a number of tiger shark: In this case, the biologist needs to sample the sharks, make measurements and organize in tables the data obtained from the two variables measured in each of the analyzed individuals.
C.An ornithologist, a scientist who studies birds, draws a sketch showing the colors of a bird’s plumage.
in this case the ornithologist had to make observations of birds of different species and through schemes report and organize according to the species what color of plumage they have.
D.An ecologist uses a computer to make a graph of the measurements of the rings of a tree:
The graph is the way in which the scientist systematizes the data for the analysis of the tree rings. these trees had to be sampled
In order to perform a more balanced form of processes inside the mammals body or as whole system there is always the requirement for having a more specific form of mechanism called as the homeostasis.
This process is required to attain a very balanced state of solutes and other liquids inside the body system of the humans. As, to have this position the mammals have certain secretions like the release of antidiuretic hormone (ADH) from the pituitary gland. Which, acts on the nephrons present inside the kidneys and directs it to absorb more amount of water and solutes, in order to prevent any more water loss.
So, basically the secretion is done for avoiding any water and solute losses from the mammals body system in any form. Which would also result in a more balanced form of blood pressure and as a whole a more balanced form of water volume inside the body.
It is an everyday life theory because it is a prediction. Molly doesn't know if she will be the best singer, but can assume that she will be because of her mother She hasn't experimented yet, so, therefore, her theory can't be supported by evidence.
