<span>Your thesis statement should have your viewpoint in it and the thing that you would be trying to prove during the course of your expository essay. Then, later in the body paragraphs, you would write things that support your viewpoint and try to present a problem or persuade someone something.</span><span />
One snapping turtle weighs 40 pounds, so 10 snapping turtles in a pond have a total weight of 400 pounds. The turtles eat largemouth bass (1 trophic level below them), and the bass in turn eat minnows (2 trophic levels below the turtles). So since only 10% of energy is passed in each trophic level, we would need:
(x lbs of minnows)(10%)(10%) = 400 lbs of snapping turtles
x = 40000 lbs of minnows (Choice C)
Answer: Neutron
Neutrons have no charge and are neutral
The answer is 9%.
To calculate this we will use some <span>formulas of the Hardy-Weinberg principle:
</span><span>p² + 2pq + q² = 1 and <span>p + q = 1
where:
</span></span>
<span>p - the frequency of the A allele.
q - the frequency of the a allele.</span>
p² - the frequency of dominant homozygote (with AA genotype)
2pq - the frequency of heterozygote (with Aa genotype)
<span>q² - the frequency of recessive homozygote (with aa genotype)</span>
<span>We know:</span>
p = 70% = 70/100 = 0.7
q = 30% = 30/100 = 0.3
We need to calculate the frequency of the genotype aa:
q² = ?
Since we know the frequency of allele q, it is easy to calculate the frequency of the genotype aa:
q² = 0.3² = 0.09 = 0.09 · 100% = 9%
Answer:
The question lacks options, the options are:
A. commensalism
B. mycorrhiza
C. parasitism
D. symbiosis
The answer is D, symbiosis (mutualism)
Explanation:
Organisms of same or different species interact with one another in their natural environment. The relationship between two organisms interacting with one another is called SYMBIOSIS. Symbiosis can be of different types depending on the effect of the relationship on the involved organisms. Symbiosis can be mutualistic, commensalistic or parasitic.
Mutualism is a kind of symbiosis in which the involved organisms benefit from the actions of one another. This is a case of the association between the root nodules of leguminous plant and rhizobium species.
Rhizobium is a bacteria genus found in the soil. They form nodules by attaching to the root of leguminous plants, which helps the plants to fix atmospheric nitrogen i.e converting gaseous nitrogen to a usable form (ammonia). In return, the plants provide organic acids for the Rhizobia bacteria, which they use as carbon and energy source. Hence, the association is a symbiotic relationship and specifically a mutualistic one.
The answer is no mycorrhiza because it is an association between a FUNGUS and a plant.
