NAME 3 SIMILARTIES AND 3 DIFFERENCES BETWEEN EACH OF THESE ZONES (AT LEAST 1 ABOTIC AND 1 BIOTIC FACTOR FOR EACH)
Sublittoral Zone & Epipelagic Zone
Abyssopelagic Zone & Hadalpelagic Zone
Neritic Zone & Oceanic Zone
Bathyal Zone & Bathypelagic Zone
Euphotic Zone & Aphotic Zone
Answer:
Like terrestrial biomes, aquatic biomes are influenced by a series of abiotic factors. The aquatic medium—water— has different physical and chemical properties than air. Even if the water in a pond or other body of water is perfectly clear (there are no suspended particles), water still absorbs light. As one descends into a deep body of water, there will eventually be a depth which the sunlight cannot reach. While there are some abiotic and biotic factors in a terrestrial ecosystem that might obscure light (like fog, dust, or insect swarms), usually these are not permanent features of the environment. The importance of light in aquatic biomes is central to the communities of organisms found in both freshwater and marine ecosystems.
Explanation:
The ocean is categorized by several areas or zones (Figure 1). All of the ocean’s open water is referred to as the pelagic zone. The benthic zone extends along the ocean bottom from the shoreline to the deepest parts of the ocean floor. Within the pelagic realm is the photic zone, which is the portion of the ocean that light can penetrate (approximately 200 m or 650 ft). At depths greater than 200 m, light cannot penetrate; thus, this is referred to as the aphotic zone. The majority of the ocean is aphotic and lacks sufficient light for photosynthesis. The deepest part of the ocean, the Challenger Deep (in the Mariana Trench, located in the western Pacific Ocean), is about 11,000 m (about 6.8 mi) deep. To give some perspective on the depth of this trench, the ocean is, on average, 4267 m. These zones are relevant to freshwater lakes as well.
The ocean is the largest marine biome. It is a continuous body of salt water that is relatively uniform in chemical composition; it is a weak solution of mineral salts and decayed biological matter. Within the ocean, coral reefs are a second kind of marine biome. Estuaries, coastal areas where salt water and fresh water mix, form a third unique marine biome.
The intertidal zone, which is the zone between high and low tide, is the oceanic region that is closest to land (Figure 2). Generally, most people think of this portion of the ocean as a sandy beach. In some cases, the intertidal zone is indeed a sandy beach, but it can also be rocky or muddy. Organisms are exposed to air and sunlight at low tide and are underwater most of the time, especially during high tide. Therefore, living things that thrive in the intertidal zone are adapted to being dry for long periods of time. The shore of the intertidal zone is also repeatedly struck by waves, and the organisms found there are adapted to withstand damage from the pounding action of the waves (Figure 2). The exoskeletons of shoreline crustaceans (such as the shore crab, Carcinus maenas) are tough and protect them from desiccation (drying out) and wave damage. Another consequence of the pounding waves is that few algae and plants establish themselves in the constantly moving rocks, sand, or mud.

What is nonflowering plants?Nonflowering plants don't produce flowers; instead, they produce microscopic reproductive elements called seeds or spores that may be used to create additional plants that look just like them.
What is strobila?A shorter stem with several altered leaves bearing sporangia makes up strobili. Gymnosperms, like all seed plants, are heterosporous. Usually, different cones are used to carry the sporangia that produce the male microspores as well as female megaspores.
Nonflowering plants like ferns, mosses, etc other nonflowering plants have reproductive organs called antheridium and archegonium. The male gametophyte's primary source of sperm cells would be the antheridium (male gametes). Numerous sperm will be produced by the antheridium for fertilization.

Statistics: Chi-squared Introduction:
A Chi-square test is used to compare observed data with expected data according to a hypothesis. For instance, if you were crossbreeding 2 heterozygous pea plants, you would expect to see a 3:1 phenotypic ratio in the offspring. In this case, if you were to breed 400 pea plants, you would expect to see 300 plants showing the dominant trait and 100 showing the recessive trait. But what happens if you observe only 260 plants with the dominant trait and 140 plants with the recessive trait? Does this mean something is wrong with Mendelian genetics or is this difference in expected results just due to chance (random sampling error)? These are the questions that can be answered using Chi-square statistics.
The results of this statistical test is used to either reject or accept (fail to reject) the null hypothesis. The null hypothesis states there is no significant difference between the observed results and the expected results. This means that if the null hypothesis is accepted, the difference in observed and expected results was just a matter of chance and so the observed results basically "fit" with what was expected.
Degrees of freedom (df) = number of independent outcomes (Y) being compared less 1
df = Y-1
At the 95% confidence interval we are 95% confident that there is a significant difference between the observed and expected results, therefore rejecting the null hypothesis.
Probability Value - Is the decimal value determined from the X2 table and is the probability of accepting the null hypothesis. A 0.05 probability value equates to a 95% confidence interval.
Problem:
The parent generation is yellowed podded and green podded pea plants. You cross a yellow podded pea plant with a green podded pea plant and you get 100% yellow podded plants in the 1st generation [F1 generation] (Phenotypic ratio 4 yellow : 0 green).
What will be the expected phenotypic ratio when you allow the F1 generation to reproduce? Work a Punnett square.
We observed 1150 yellow and 350 green when actually crossing F1 generation.
Would this be a consistent with what was expected?

We perform a Chi-square analysis to find out if the difference between observed and expected is due to chance or not. In this example, 1) FD=1 / 2) X² = 2.22 / 3) Fail to reject the null / 4) 75.
-------------------------------------------------
Since a complete introduction to Chi-square was provided, we will proceed with the problem analysis.
1st Cross: Yellow x green
Parentals) YY x yy
F1) 100% Yy, yellow
2nd Cross: Yellow x yellow (From F1)
Parentals) Yy x Yy
F2) 3/4 = 75% of the progeny is expected to be yellow
1/4 = 25% of the progeny is expected to be green
We know from the data, that there are 1500 individuals in F2. So we can get the expected number of individuals from this data.
100 % of the progeny ----------------------- 1500 individuals
75 % yellow ------------------------------------X = 1125 individuals
25% green -------------------------------------X = 375 individuals
We assume the population is in H-W equilibrium, but we observe differences in what we expect to see and what we actually see. We want to know why.
H₀ = there is no significant difference between the observed results and the expected results. The difference in observed and expected results is by chance.H₁ = The difference in observed and expected results is not just a matter of chance.Now we will make a table resuming information
Yellow Green
Observed 1150 350
Expected 1125 375
(Obs-Exp)²/Exp 0.555 1.666
X² = Σ(Obs-Exp)²/Exp = 0.555 + 1.666 = 2.221Y = 2 df = Y-1 = 2 - 1 = 1Significance level / probability value = 0.05Table value / Critical value = 3.841P₀.₀₅ > X²3.841 > 2.221We can see that the table value is greater than the X² value, so there is not enough evidence to reject the null hypothesis.
The genotypes might be in equilibrium, and there might be independent assortment.
This results suggest that the difference between the observed individuals and the expected individuals is by random chances.
So now let us answer the questions,
1) Determine the degrees of Freedom of the phenotypic ratio for this genetic cross ⇒ DF = 2 - 1 = 1
2) What is the result of your Chi-squared analysis? ⇒ X² = 2.22
3) Do we fail to reject or reject the null hypothesis? ⇒
We Fail to reject the null hypothesis. There is not enough evidence to reject it.
4) If we flipped a coin 100 times. Which of the following is the minimum number necessary to achieve significance? 75 is the minimum number necessary to achieve significance
