Types of symbiosis and examples

“List two important types of symbiosis, and define and provide an example of each.” “Define detritus feeders and decomposers, and explain their importance in ecosystems.”

Biology

1. How are single traits inherited? Distinguish between the terms, phenotype and genotype. 2. Name five kinds of aquatic ecosystems. Describe human impacts that affect the following: ocean coral reef freshwater lakes

Biology

1. How does mitotic cell division produce genetically identical daughter cells? Include each stage of mitosis and what happens during each. 2. Describe differences between prokaryotic and eukaryotic cells.

Ecosystems

Ecosystems such as wetlands, rivers, watersheds, forests, ponds, mangroves, etc. sometimes undergo restoration. Planning, implementing, mitigation, monitoring and management go into restoration projects. Do you think the benefits are worth the cost for ecosystem restoration? Why or why not?

Questions about the scientific method

1. List and describe the steps of the scientific method. 3. Is it sufficient to do a single experiment to test a hypothesis, why or why not? 4. What do you call a sample that goes through all the steps of an experiment but does not contain the factor being tested? 7. Why is it important to test one substanc ...continues

What types of benefits and downfalls could you see happening with this type of policy? What impacts could it have on the population both scientifically and socia ...continues

Ecosystem

In an ecosystem, interaction occurs between communities. Energy is transferred from one organism to another through the food chain. What are the three trophic levels? Give an example of each. What trophic level do you think is the most important in the ecosystem and why? What is biodiversity? Is it important? Relat ...continues

How ecological communities and food webs interact.

Give an example of how ecological communities and food webs interact.

Advance a simple, brief hypothesis about what causes histamine release from mast cells that is consistent with all the data.

Mast cells contain granules of histamine which are released upon exposure to allergens. Depending upon location and amount, this histamine-release can cause everything from watery eyes to life-threatening bronchospasm. It was long thought that this might have an immunologic basis. To probe this possibility, an investigator g ...continues

q4 need concise answers

4. An investigator performed cytofluorimetric (FACS) analyses of a mouse strain called C.B20 and a spontaneously arising point mutant that arose in the same strain called "C.B20 scid." Splenocytes from each strain were stained with anti-IgM (green) and anti-CD3 (red), then analyzed. The proportion of cells falling into each phen ...continues
