If the mutation gives an organism a trait that helps them survive, that mutation will get passed on to future generations. ... Genetic variation is multiple genes and traits in a population. The greater the diversity of genes in a population, the greater chance the population will survive a changing environment.
When forests have been cut down, new native trees can be planted
Answer:
C- Dominant, but not sex-linked
Explanation:
The disorder is not sex-linked because almost equal numbers of people have Pinocchio nose syndrome. If the disorder was sex linked you would have way more men than women having the disorder.
You can tell that the genetic disorder is dominant because there is a 3:1 ratio for those who have the disorder.
36 out of 47 men ≈0.765
37 out of 53 women≈0.69
These numbers approximate a 3:1 ratio (even if it's not exact), meaning that the disorder is most likely dominant
The right answer is A rapid temperature increase will give a melting point range that is too high.
The melting point is determined in a capillary tube. it means the temperature at which the substance is completely melted, indicated by the disappearance of the solid, will not differ by ± 4 ° C from the given value, unless otherwise indicated.
The following technique can be applied to determine the melting point:
Grind some amount of substance in a small mortar. Place in a vacuum desiccator containing silica gel or phosphorus pentoxide and allow to dry for 24 hours at room temperature (unless another method of drying is indicated in the test protocol) . Introduce the substance into a dry capillary tube 1 mm inside diameter to form a column about 3 mm high. Heat the melting device to a temperature 5 to 10 ° C below the expected melting temperature and adjust the heating so that the temperature of the enclosure rises by approximately 1 ° C per minute. Introduce the capillary tube containing the substance into the heated chamber and note the temperature at which the agglomerated substance becomes completely transparent; this temperature constitutes the melting point.
They are neither, they do not have the mechanism to ingest or produce food.
