Explanation:
Modeling a Food Web
In this activity, you will build a model of a food web in a specific aquatic ecosystem. You will then use the model to explain what can happen to the competition in the ecosystem if environmental factors change because of natural factors and human interference.
Total time: 2 to 3 hours
You will need these materials:
paper
a pen or a pencil
word-processing or graphic-design software
Part A
Begin by selecting a freshwater or marine aquatic ecosystem as a model for your food web. Be specific. Choose a specific lake. Or, if you choose an ocean ecosystem, identify its geographical area and depth. Keep in mind that deep-sea organisms live in a completely different environment than surface aquatic organisms.
Next, conduct research on the following conditions in the ecosystem you chose. They influence the types of organisms that can live there.
geographical features
temperature
depth/light availability
salinity
pH
unique features that contribute to the ecosystem, such as other bodies of water that connect to it, unusual chemistry, and climate
Using the information you gathered, write a paragraph that describes conditions in the ecosystem.
<span>cytoskeleton is composed of globular proteins placed in a way similar to chains, ou queues. they are only few types of these globular proteins, and they dispose following precise patterns. actin and tubulin are made of actin subunits and a- and b-tubulin alternating subunits respectively.
antibodies are proteins too. they are composed by two regions. one is common to all antibodies, one is specific for interaction with a substrate through a mechanism of the kind key-and-lock.
to locate where actin and tubulin are in a cell, you can simply construct specific antibodies. you just have to keep the common part of the antibody and bind to it a chromophore (a molecule capadble of emitting fluorescence if irradiated with light at a specific wavelenght). then you have to bind to this part a suitable "lock" for actin or tubulin. you can only do this if you know the structure of actin and tubulin and their phisical properties, which can determine what kind of interactions they can establish with precise molecules.</span>
That would be true! (please rate)
Answer:
B. There are no producers in the benthic zone that relay on photosynthesis.
Explanation:
There are no producers present in the benthic zone because benthic zone is located in higher depth where there is no sunlight so no photosynthesis occurs there. We know that photosynthesis only occurs in the presence of sunlight, if there is no sunlight then there is no photosynthesis occurs and as a result no producer can survive there so we can conclude that there is no producers present in the benthic zone .
Answer:
<em>The correct option is D) need to be aware that if any of his garlic plants became diseased, it could very likely infect the entire crop</em>
Explanation:
If cloves from a bulb are taken and grown, then the plants formed will be identical to each other. As a result, there will be no genetic varieties in the garlic plants being produced. Hence, when a diseases eradicates, it will affect the entire plants of the garden as they would be genetically identically, Variations would have allowed some of the plants to be resistant for the disease and hence some of the plant species could be saved by genetic variations.
