Give an example ecological disturbance. Light Disturbance? Extreme Disturbance.
Answer:
In contrast, major disturbances include large-scale wind events (such as tropical cyclones), volcanic eruptions, tsunamis, intense forest fires, epidemics, ocean temperature changes stemming from El Niño events or other climate phenomena, and pollution and land-use conversion caused by humans.
Explanation:
All plants are subject to photorespiration, but not all plants are equally affected by photorespiration due to the environment in which they live.Choose one of the two pictures (A or B) and explain why that environment would increase the likelihood that those plants would be greatly affected by photorespiration. Your answer should describe the nature of the environmental impact and how the impact would affect the anatomy and physiology of photosynthesis of the plant.The environments are:A. Desert. Prairie
Answer:
Desert.
Explanation:
Photorespiration occurs in C3 plants because their photosynthetic activities are disturbed due to high temperature of the environmental while on the other hand, C4 plants has absent this photorespiration process. The desert environment has direct impact on the plants having photorespiration due to its high temperature of the surrounding as compared Prairie where the environment is moderate so the C3 plants has high chances of photorespiration in desert condition as compared to Prairie.

What causes weather fronts to move?
Answer:
A warm air mass pushes into a colder air mass (the warm front), and then another cold air mass pushes into the warm air mass (the cold front). Because cold fronts move faster, the cold front is likely to overtake the warm front. ... The warm air rises as these air masses come together.
Explanation:
Hope this helps!!
Answer:
when warm air rises cold air covers the spot it was in so its a cycle warm air rises cold air fills its place
Seed size in a plant is a polygenic characteristic. A grower crosses two pure-breeding varieties of the plant and measures seed size in the F1 progeny. She then backcrosses the F1 plants to one of the parental varieties and measures seed size in the backcross progeny. The grower finds that seed size in the backcross progeny has a higher variance that does seed size in the F1 progeny. Explain why the backcross progeny are more variable.
Answer:
The F1 progeny is completely heterozygous for the loci of interest since they were obtained by mating between two pure-breeding plant lines. In the next generation, the backcross progeny will have homo-zygous individuals and therefore they will be more variable, resulting from meiosis in F1 hybrids
Explanation:
An F1 resulting from the cross between two pure-breeding plant lines will produce all hybrid individuals, all of them genetically (and phenotypically) identical. Meiosis in F1 hybrids is well known to produce homo-zygous genotypes and thus increases genetic diversity in progeny. For instance, for a single locus, the expected ratio of genotypes obtained from crossing two heterozygous parents is 1:2:1, i.e., one homo-zigous dominant individual, two heterozygous individuals (genetically identical to the parents) and one homo-zygous recessive individual; while the expected phenotypic ratio is 3:1 (i.e., 3 dominant expressing: 1 recessive expressing).

Where do majority of tornadoes occur in the United States?
Answer:
central united states
Explanation:
mainly in this area because of cold air coming in from canada and warmer air coming from the gulf of mexico meeting and causing tornados.
Answer:
A majority of tornadoes that occur in the United States, occur in the Midwest and Southeast region of the United States.
Explanation:
Tornadoes can impact just about every U.S. state, but the majority of these storms are concentrated in states throughout the Midwest and Southeast. In fact, of the average 1,137 tornadoes that occur in the United States each year, 64% of them form in states located in “Tornado Alley” and “Dixie Alley”, two regions with a disproportionately high frequency of tornadoes due to atmospheric conditions that persist for long stretches of the year.
With an average of 140 tornadoes annually, Texas is the most tornado-prone state in the U.S., followed by Kansas with 80 and Florida with 59, according to National Oceanic and Atmospheric Administration data.
Top five states with the most tornadoes

Explanation:
The Offspring produced by a cross between two given types of plants can be any of the three genotypes denoted by A, B, and C. A theoretical model of any of the three genotypes denoted by A, B, and C should be in the ratio 1:2:1. For experimental verification, 100 plants are bred by crossing the two given types. Their genetic classifications are recorded. Do these data contradict the genetic model
Complete question:
The offspring produced between two given types of plants can be any of the three genotypes, denoted by A, B and C. A theoretical model of gene inheritance suggests that the offspring of types A, B and C should be in a 1:2:1 ratio (meaning 25% A, 50% B, and 25% C). For experimental verification, 100 plants are bred by crossing the two given types. Their genetic classifications are recorded in the table below.
Genotype Observed frequency
A → 18 individuals
B → 55 individuals
C → 27 individuals
Do these contradict the genetic model?
Use a 0.05 level of significance.
Determine the chi-square test statistic.
Answer:
Do these contradict the genetic model? No, according to the chi-square test, there is not enough evidence to reject the null hypothesis of the population being in equilibrium.
Explanation:
Available data:
Crossed genotypes: twoGenotypes among the offspring; Three → A, B, and CExpected phenotypic ratio → 1:2:1Total number of individuals, N = 100A = 18 individualsB = 55 individualsC = 27 individualsSo, let us first state the hypothesis:
H₀= the population is equilibrium for this locus → F(A) = 25%, F(B) = 50%, F(C) = 25% H₁ = the population is not in equilibriumNow, let us calculate the number of expected individuals, according to their expected ratio.
4 -------------- 100% -------------100 individuals
1 --------------- 25% -------------X = 25 individuals A
2 -------------- 50% -------------X = 50 individuals B
1----------------- 25%--------------X = 25 individuals C
A B C
Observed 18 55 27 Expected 25 50 25 (Obs-Exp)²/Exp 1.96 0.5 0.16(Obs-Exp)²/Exp
A) (18 - 25)²/25 = 49/25 = 1.96
B) (55 - 50)² / 50 = 25/50 = 0.5
C) (27 - 25)²/25 = 4/25 = 0.16
Chi square = X² = Σ(Obs-Exp)²/Exp
∑ is the sum of the terms O are the Observed individuals: 2 in chamber B, and 18 in chamber A. E are the Expected individuals: 10 in each chamberX² = ∑ ((O-E)²/E) = 1.96 + 0.5 + 0.16 = 2.62
Freedom degrees = 2
Significance level, 5% = 0.05
Table value/Critical value = 5.99
X² < Critical value
2.62 < 5.99
These results suggest that there is not enough evidence to reject the null hypothesis. We can assume that the locus under study in this population is in equilibrium H-W.

Which of the following best describes the difference between population size and population density?
A. Population density measures the abundance of an organism, whereas population size measures the distribution
B. Population size measures the abundance of an organism, whereas population density measures the distribution
C. Population size measures abundance, but population density measures how rapidly the size changes
D. Both variables measure abundance, but population density takes the into account the size of individuals, not just the number of individuals in the population
E. None of these descriptions are correct
Population size refers to the number of individuals, while population dendity refers to the number of individuals per unit of area or volume. The correct option is E. None of these descriptions are correct.
------------------------------------------------
Before answering the question, let us review the concepts of population size and density.
Population size refers to the number of individuals composing a population.Population size might determine the destiny of the population.
A small population has more chances to get extinct than a bigger-sized population.
Density refers to the average number of individuals of the same species per unit of area or volume. This measure may be more significant than population size.
To estimate population density there are two possible methods: Direct methods and indirect methods.
Abundance indexes are the parameters related to density, and they reflect changes that might happen in the target population density. They are commonly used to compare population sizes.
According to these concepts, the correct option is E. None of these descriptions are correct.

4. Predict what a fossil that illustrates the
evolution of a bird from a reptile might look
like.
Answer:
The discovery that birds evolved from small carnivorous dinosaurs of the Late Jurassic was made possible by recently discovered fossils from China, South America, and other countries, as well as by looking at old museum specimens from new perspectives and with new methods. The hunt for the ancestors of living birds began with a specimen of Archaeopteryx, the first known bird, discovered in the early 1860s. Like birds, it had feathers along its arms and tail, but unlike living birds, it also had teeth and a long bony tail. Furthermore, many of the bones in Archaeopteryx's hands, shoulder girdles, pelvis, and feet were distinct, not fused and reduced as they are in living birds. Based on these characteristics, Archaeopteryx was recognized as an intermediate between birds and reptiles; but which reptiles
