Answer:
This is an example of recessive epistasis.
Explanation:
Gene interactions happen between genes at different levels and have implications in the phenotypic expression, causing a wide genetic variability.
Epistasis means "interruption" and refers to interactions between genes located in different loci in the same chromosome. An “epistatic gene” can alter, influence, or suppress the expression of a "hypostatic gene". When the epistatic gene is recessive, the interaction is known as "recessive epistasis".
Observing the altered phenotype proportions of the offspring can reveal which interaction is operating in the trait determination.
In recessive epistasis, the proportion is 9:3:4.
B. beginning of multicelled life
C. first appearance of most invertebrates
D. dominance of non avian dinosaurs
Answer:
C) first appearance of most invertebrates.
Explanation:
The Cambrian Explosion occurred 542 mya. The earliest complex animals arose in the sea at the beginning of the Cambrian Explosion. It would take another half a billion years for mammals to rise. Multicellular life dates back 1.2 bya, but more cpomplex life, such as animals, did not occur until the Cambrian Explosion. In the beginning of the Cambrian Explosion, many soft-bodied animals, such as jellyfish and sea anemones appeared.

C

Answer:
Heart disease is the leading cause of the death in the United States. It is also a major cause of disability. There are many things that can raise your risk for heart disease. They are called risk factors. These ahould be considered as starters for a teaching plan to adults with no medical background, the risk factors that can be changed and the ones that cannot.
The factor above are considered as risk that cannot be changed, there are some risks that women and men have differently for example, progesterone protects women from heart diseases but if the patient develops diabetes women are mostly likely to have a heart disease. Also age is factor that can't be changed or controled men over 45 are more likely to have a heart disease and women over 55 are more likely to have a heart disease.
Even though there are some factor that can be controlled by taking care of yor health, for example; Controlling yor blood pressure, have a healthy diet with lots of vegetables and fruits, following the food pyramid for a balanced meal everyday, practice exercise and avoid sedentarism, stop smoking it will only increase your blood pressure, sleep well, you should be sleeping from 7 to 9 hours a day, control your weight, the fat in your blood can cover your veins and arteries, mainly the coronary ones which are in charge of supplying oxygen-rich blood to the heart. Finally you can also limit and control the amount of alcohol you ingest and the amount of stress you deal everyday.
These are basic terms to educate adults with no health backgrounf about prevention of heart diseases.
