The change most likely to favor this is Independent, unique mutations occurred in each population that rendered enhancers in the armor pathway useless, which were then favored by natural selection.
What is Natural Selection?Natural selection is the variation in individual survival and procreation brought on by phenotypic variances.The evolution of a population's heritable features across generations is a fundamental mechanism of evolution.By contrasting it with artificial selection, which in his opinion is intentional and natural selection is not, Charles Darwin popularized the phrase "natural selection."Every population of organisms contains variation. This happens in part because an organism's genome might experience random mutations, which its descendants may inherit. Individuals' genetics and environments interact throughout their lifetimes to produce different phenotypes.A genome's environment comprises the abiotic environment as well as the molecular biology of the cell, other cells, individuals, populations, and species.The population changes as a result of individuals with specific variants of the trait having a higher chance of surviving and procreating than those with other, less successful versions.Fecundity selection and sexual selection, which are now frequently included in natural selection, are other factors that affect reproductive success.Know more about Natural selection https://brainly.com/question/9830102

Question:
I hope you are trying to ask the question below:
Imagine a scenario in which several lakes have been colonized by marine-origin sticklebacks. In each lake, body armor disappears over time. Which change most likely caused this?
a. Independent, unique mutations occurred in each population that rendered enhancers in the armor pathway useless, which were then favored by natural selection.
b. Each population had the exact same mutation in a protein coding gene that produces the armor, which increased in frequency by natural selection.
c. Novel trans-regulatory elements functioned to build new, armorless morphologies that increased in frequency because of gene flow from oceanic populations.
d. Lack of armor reduces fitness, so only genetic drift could cause the armorless condition to increase in frequency.

After returning from his journey west, stephen h. long perpetuated the myth that the region between the missouri river and the rocky mountains was unfit for cultivation.
Stephen Harriman Long (1784–1864) was an American military explorer best known for leading the 1820 expedition to what is now Colorado. On his journey map, he eminently called the arid Great Plains the "Great American Desert".
Even as late as 1823, Major Long of the Army Engineers noted that much of the land between the Missouri River and the Rocky Mountains was "almost wholly unfit for cultivation, and of course uninhabitable by a people depending on agriculture for their subsistence."
Today, the adaptation of technology to semi-arid areas and the development of new technologies have made the Great Plains one of the most productive agricultural regions in the world.

Explanation:
Only a narrow band of territory in southern and eastern Canada has the __________ suitable for agricultural production and widespread settlement. (Select all that apply.)
Only a narrow band of territory in southern and eastern Canada has the Climate and Physical geography suitable for agricultural production and widespread settlement.
What is Geography and Climate?The study of the Earth's natural physical features and human interactions with those features is called geography.
While the study of the Earth's atmosphere and long-term weather patterns over a particular region is called climatology. Climate is studied over a broad range of spatial and temporal scales.
For example, scientists may focus on the climate of a city, a geographic region, a continent, a hemisphere, or the planet as a whole. Climate is also studied on time scales ranging from as short as a few decades to scales spanning millions of years.
Geography and climate are connected in several ways. For example, the topography and nature of the materials that make up the ground surface (e.g., type of vegetation, sand, water, asphalt, etc.) The distribution of heat at the ground surface determines ambient temperatures and the rate of water transfer from surface regions to the atmosphere through evaporation, a key process in determining a region's climate.
Therefore, we can conclude that the correct option is both, climate and physical geography

Updrafts dominate the cumulonimbus cloud during the ________ in the life cycle of an air mass thunderstorm.
Updrafts dominate the cumulonimbus cloud during the cumulus stage in the life cycle of an air mass thunderstorm.
Although first cumulus clouds frequently perish, their deaths are not in vain. In the same column as the initial cumulus, new cumulus clouds frequently form, benefiting from the water vapor from earlier-evaporating cloud particles.
Even if entrainment into the newly forming cumulus still continues, the air that is mixing into the cloud is more humid than before, which, as you may remember, reduces the possibility of net evaporation (and evaporational cooling).
A series of cumulus clouds can now develop and dissipate in a single column of air if there is an adequate supply of low-level moisture and persistent positively buoyant parcels throughout time.
Fair-weather cumulus eventually gives way to cumulus congestus, which is a towering cloud.

What prevents each spot on earth from experiencing two high tides and two low tides a day?
Because of the moon's gravitational pull on the Earth and the Earth's rotational force, coastal areas experience two high and two low tides.
Tides are the alternating movement of water along the coast. High tide is when water advances to its farthest extent onto the oceanfront. Low tide is when it recedes to its farthest extent. The side of the Earth closest to the Moon experiences the Moon's strongest gravitational pull, causing sea levels to rise and tides to occur. On the far side of the Moon, the Earth's rotational force is stronger than the Moon's gravitational pull. The sun's gravitational pull also plays a minor role in the formation of tides. Tides move around the earth as bulges in the ocean.

the content of carbon di oxide in the atmosphere keeps on fluctuating. Explain
Answer:
Plants play a large factor in fluctuating levels of CO2 within the atmosphere. Plants, through photosynthesis, convert CO2 gas into sugars and O2 gas powered through sunlight. In different seasons, the plants become active or deactivate and can undergo different amounts of photosynthesis. For example, during the winter, CO2 is very high, as many plants are not undergoing photosynthesis and cannot convert the CO2 into O2. But in spring, CO2 is drastically lowered as they are far more active in converting the atmospheric gas.
