You perform an in situ hybridization on Drosophila melanogaster embryos. You apply a probe labeled with a fluorescent stain that

is complementary to mRNA transcripts of the gene hunchback. In early stages of embryogenesis you observe fluorescence for the entire anterior half of the embryo only. In embryos at a later stage of development you see the same pattern in the anterior, and also a stripe of fluorescence in the posterior half. What can you conclude about the expression of hunchback from this?

What connection is there between Photosynthesis and Glucose production
attashe74 [19]

Answer:

The relationship between photosynthesis and cellular respiration is such that the products of one system are the reactants of the other.

Explanation:

For example, the output of photosynthesis is the input of glucose production or cellular respiration. The output of glucose production is the input of photosynthesis. Photosynthesis involves the use of energy from sunlight, water, and carbon dioxide to produce glucose and oxygen. Cellular respiration uses glucose and oxygen to produce carbon dioxide and water.  To emphasize this point, even more, the equation for photosynthesis is the opposite of cellular respiration.

[14] considering the food web, which trophic levels would be impacted by lower yields of fungi (mushrooms) due to, for example,
LekaFEV [45]

A reduction in number of fungi in the food web lead to a decrease in the producers and the other consumers.

  • Trophic levels are hierarchies in an ecosystem. The trophic level of an organism is the position in the food chain. A trophic level can be defined as a group of organisms in the same level in a food chain or food web.
  • Organisms are organized into various trophic levels. They can either be producers, consumers or decomposers. Decomposers include bacteria and fungi that feed on dead organic matter.
  • If fungi were to  affect by acid rain that will lead to low yields and then  there would be few decomposers in the food web and hence there would be no recycling of nutrients in the food web.
  • Fungi help to remove the environment of the dead organic organisms and add nutrients to the soil for use by the primary producers.
