Corn kernels can be high in starch (starchy) or high in sugar (sweet). The allele for starchy kernels (H) is dominant to the allele for sweet kernels (h). Each kernel on an ear of corn represents an individual offspring. A particular ear of corn has 92 starchy kernels and 88 sweet kernels .

A group of scientists are studying a disease which is caused by contaminated food. The chemicals in this food cause harm to the body through interactions with the digestive and the immune systems. Which of the following are the scientists most likely to find in their research?
(A) When the contaminated food is eaten, the immune system prevents the harmful chemicals from entering the digestive system.
(B) The harmful chemicals enter the immune system through a break in the skin. The chemicals are then passed to the digestive system by the cardiovascular system.
(C) The harmful chemicals enter the digestive system through contaminated foods. Once in the body, the chemicals reduce the ability of the immune system to react to pathogens.
(D) The immune system transforms the harmful chemicals in the contaminated food into a different form of chemical, which is then broken down and absorbed by the digestive system.

Describe the flow of energy in a marine food web.
Include at least 5 organisms.
Please answer only if you actually have an answer, no links.
Answer:
The flow of energy in a marine food web include the following:
Plankton⇒shrimp⇒ salmon⇒ seals⇒ whales
In the marine ecosystem, the plankton which are plants are the primary producers while the whales are the tertiary/quaternary consumers as they are at the top of the web.

A food web comprises of food chains which are interconnected and also

Describe the flow of energy in a marine food web.
Include at least 5 organisms in your answer.
1. The energy flow takes place via food chain and food web. During the process of energy flow in the ecosystem, plants being the producers absorb sunlight with the help of the chloroplasts and a part of it is transformed into chemical energy n in the process of photosynthesis.
2. This means that they form a kind of cycle. The extinction of one organism can cause a ripple effect that impacts all of the species involved in that food web. This means that one organism would destabilize the whole food web. The extinction of a keystone specie might force all the organisms to adapt, because this specie is one whose presence and activities strongly affect other species. In other cases the ecosystem is the one that adapts to the lack of the organism. The extinction of species with a strong interaction in the food web occur more often that the others that do not have much interaction. In some cases the food web would be affected because some animals would not have a source of food, therefore they would not have energy. That way they would have to find another way to get the food or in extreme cases they could also get extinct. An example is like the one in the picture, if the phytoplankton dies or decreases its number, its consumers would decrease their number as well, eventually the decrease of a very tiny organism would end up to the extinction of a large organism such as the killer whale or elephant seal.
