Tickleback evolution lab final quiz 1. how did some ancestral sea-run stickleback populations come to live exclusively in fresh water? these populations swam to freshwater lakes to spawn and then never returned to the ocean because there were fewer predators in lakes. they became trapped in lakes that formed at the end of the last ice age. they don't actually live exclusively in fresh water; they only live in fresh water at certain stages in their lives. they developed traits that made them better adapted to fresh water and, as a result, had to move to a freshwater environment to survive.
Answers
Answer:
The correct answer is "some stickleback populations come to live exclusively in fresh water they became trapped in lakes that formed at the end of the last ice age".
Explanation:
There are different types of speciation. Allopatric speciation consists of the geographic separation of a continuous genetic background so that it can give place to two or more new geographically isolated populations. Some barriers might impede the genetic interchange or genetic flux, making a place to two new populations that are separated and can not get together to mate anymore. Glaciation is one of the most important drivers of speciation and production of different phylogeographic structures by vicariance. Glacials originate isolated gene-pools that accumulate differences that end in reproductive isolation. Melting of the ice also generated divergence and speciation, as land appearance acted as a barrier for some populations.
During the last glaciation, stickleback fishes were able to reach certain new places or areas that provided better conditions to inhabit. There were fewer predators and more available food sources that made these new areas to be a better choice. These new grounds were lakes and were the product of ice melting. But at a certain point, as ice melting increased, the land started to show up again and became a barrier for this species. Animals that were living in lakes could not go back to the sea, they were trapped so they had to adapt to living exclusively in lakes. This species diverged and suffered speciation.

When population grows past the ecosystem’s carrying capacity, what happens to the population?
A. Continues to grow
B. The population starts to die off to return to carrying capacity
C. The population will go extinct due to lack of resources
D. The population grows, then finds a new carrying capacity.
Answers
Answer:B animals will die since there arent enough resources for everyone until there is enough for the remaining population to use
When Population growth past the ecosystem’s carrying capacity, then the population starts to die off to return to carrying capacity (Option B).
The carrying capacity refers to the maximum number of individuals of a population that can be supported by particular environmental conditions.Carrying capacity depends on both biotic factors (e.g., presence of predators, food availability, etc.) and abiotic factors (e.g., water availability, living space, etc).When a population passes its carrying capacity, then the environment becomes unsuitable for the individuals of that population to survive.In conclusion, when population growth past the ecosystem’s carrying capacity, then the population starts to die off to return to carrying capacity (Option B).

An interglacial is a period of time that occurs between Ice Ages. During previous interglacials, the CO2 levels in the atmosphere were about 300 parts per million (ppm). In 2013, they were approximately 420 ppm. Rounding to the nearest percent, what is the percent increase in CO2 between these two time periods?
Answers
Answer:
40% increase
Explanation:
Percentage Increase Formula:
Percentage Increase=[(Final Value−Starting Value)/|Starting Value|] ×100%
To Calculate Percentage Increase:
1) Subtract final value (later value) minus starting value (initial value)
2) Divide that amount by the absolute value of the starting value (initial value)
3) Multiply by 100 to get percent increase
Keep in mind: If the percentage is negative, it means there was a decrease and not an increase.
So for your problem,
[(420-300)/300]*100% = 40% increase

The orbital speed of the galaxies in the cluster is fast enough to keep the cluster intact.
Baryonic matter provides the mass and gravity needed to keep the cluster together.
Answers
Answer:
1. T^2=r^3 ( or T² = r³)
2. "The exposed water reflects back more sunlight than did the ice"
and
"The exposed water absorbs more thermal energy from the sun than did the ice'
3. Dark matter provides the mass and gravity needed to keep the cluster together.
Explanation:
1. Which is the simplified version of Kepler’s third law when one of the planets being compared is Earth?
Kepler's Third law of planetary motion is the ratio of the square of the orbital period of a planet is to the radius of orbit of a planet or those of other planets.
This means that, Kepler's Third law of planetary motion states that the square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit.
Mathematically, Kepler's Third last is represented as
T² : r³
= T² = r³
Therefore, the second option,T^2=r^3 which is equivalent to T² = r³ is the correct option
2. Which of the following are effects of melting sea ice? Select the two correct answers.
The melting of sea ice causes a lot of changes in the climate of an environment.
The presence of sea ice in oceans, reduces the surface area thereby causing a minimal reflection of sunlight but once sea ice melts, the surface area of the water is increased and this would results in a reflection of sunlight.
The sea ice absorbs less thermal energy or radiation from the sun(solar energy) and keeps the surface cooler but once the sea ice is melts, the resulting water, absorbs a lot of thermal energy or radiation from the sun, causing the surface of the water to be hot.
Therefore, the options "The exposed water reflects back more sunlight than did the ice" and
"The exposed water absorbs more thermal energy from the sun than did the ice" are the correct options.
3. A group of scientists are studying observable matter in a cluster of galaxies. They conclude that the cluster has only a small percentage of the mass required to keep it from flying apart. Why does the cluster remain intact?
It has been observed that galaxies present in the solar system have an attraction for one another such that they are drawn to each by force of gravity that is present in the solar system. And because of these, galaxies form clusters in the solar system.
Dark matter is a large amount of matter that is present in the solar system. Dark matter is the reason by which galaxies can form and maintain the clusters that they form around each other because it provides them with the force of gravity and sufficient mass that the galaxies require to prevent them from separating or flying away(apart) from one another
Therefore, the option "Dark matter provides the mass and gravity needed to keep the cluster together" is correct.
The simplified version of Kepler’s third law in a situation when one of the planets is compared to Earth will be T³ = T².
The effects of melting sea ice include:
The exposed water reflects back more sunlight than did the ice.The exposed water absorbs more thermal energy from the sun than did the ice.A cluster will remain intact because the dark matter provides the mass and gravity needed to keep the cluster together.
It should be noted that Kepler's third law of planetary motion simply represents the ratio of the square of the orbital period of a planet is to the radius of orbit of other planets. This can be expressed mathematically as T³ = T².

32. Briefly describe how sedimentary rocks form. How do both of the two main subcategories form?
33. Briefly describe how metamorphic rocks form. How do both of the two main subcategories form?
Answers
Answer: 31, Igneous rocks are formed from lava or magma. Magma is molten rock that is underground and lava is molten rock that erupts out on the surface. The two main types of igneous rocks are plutonic rocks and volcanic rocks. Plutonic rocks are formed when magma cools and solidifies underground
32, Sedimentary rocks can be organized into two categories. The first is detrital rock, which comes from the erosion and accumulation of rock fragments, sediment, or other materials—categorized in total as detritus, or debris. The other is chemical rock, produced from the dissolution and precipitation of minerals
33, Rocks are formed on Earth as igneous, sedimentary, or metamorphic rocks. metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock.

Select all statements which describe the role of calcium in the soil/plant environment.
Answers
Answer: the statements are not given, so I will state the role of calcium in plants.
Calcium pectate, is responsible for holding together the cell walls of plants, it is also used in activating certain enzymes and to send signals that coordinate certain cellular activities in plants. Calcium helps to maintain chemical balance in the soil, it reduces soil salinity, and improves water penetration within soil.
When there is calcium deficiency, it leads to localized tissue necrosis causing stunted plant growth, dead leaf margins or curling on the leaves, and eventual death of terminal buds and root tips of the soil/plant.
Excess levels calcium in the soil can reduce a plant's uptake of other important nutrients such as phosphorus, magnesium, boron, potassium, copper, zinc or iron, leading to deficiencies of these nutrients.
Do you think that the frequency of echolocation sounds from bottlenose dolphins will be higher or lower than that of the blue whale call described in activity one?
Answers
Answer:
The frequency is higher in case of echolocation sounds produced by Bottlenose dolphins. It falls in the range 40,000 Hz to 130,000 Hz, while the calls made by blue whales lies in the range of 30 Hz to 8,000 Hz.
However, the blue whale calls last a lot longer than the echolocation sounds made by the dolphins. A typical blue whale call is between 10 to 30 seconds long, while the dolphin's click is only 50 to 128 microseconds long.
