Water is essential to life because it creates us humans, plants, animals, etc. So, if we find water on Mars it would be important because water is essential to life, meaning we would know that there would be some kind of life on Mars because water makes up anything.
During Physical Change there would be a re-arrangements of atoms or molecules, changes of the arrangement may be change in the distance between atoms or molecules, change in the crystal form.
Good luck!
Answer:
C) The ancestral population probably had this type of blood pigment, but it was lost through genetic drift in the other 29 populations.
Explanation:
The presence of a blood pigment that is extraordinarily effective at carrying oxygen is a beneficial genetic trait and should be favored by natural selection. According to the given information, the organisms of only a single population of pupfish have this trait while the others do not have it.
This means that the trait was present in the ancestral populations of the pupfish but was lost in the other populations due to some accidental/chance event. Loss or fixing of an allele by a chance event is called genetic drift. It does not include any natural selection but results in a random change in the allele frequencies of a population. Therefore, loss of the trait by genetic trait might have occurred in the other populations.
Answer:
To answer this question, we use the Homeostatic Model Assessment (HOMA).
Explanation:
What is HOMA?
The principle of HOMA is that blood glucose and insulin concentrations are related by the feedback of glucose on β-cells to increase insulin secretion. The model assumes that normal-weight subjects aged less than 35 years have an insulin resistance (R) of 1 and 100% β-cell function.
In conclusion, the secretion of insulin from glucose release energy for the cell to function
