Tenochtitlán, the Aztec capital city, was built where it was because it was located on an island in the middle of a lake, providing both access to water and protection from enemies.
Tenochtitlán was built on an island in the middle of Lake Texcoco, which was a large lake located in the Valley of Mexico. The location was chosen because it provided the Aztecs with access to water, which was essential for irrigation, transportation and food. The island location also provided a natural barrier and protection from enemies, making it a strategic location for a city. The Aztecs built causeways to connect the island to the mainland, which allowed them to expand the city and control the trade routes in the region.

The material immediately surrounding an artifact, usually some sediment such as gravel, sand, or clay, is known as the Matrix.
What is an Artifact?An artifact is something that was created by a human. Art, tools, and clothes made by people from any period or location are considered artifacts. The phrase can also be used to describe an object's remnants, such as a piece of broken pottery or glass. Scholars who seek to study a culture can learn a lot from artifacts. In order to understand the past, archaeologists explore the locations where ancient cultures once existed. Artifacts may serve as the only hints regarding how people lived in the past because many ancient cultures lacked written languages or consciously refrained from writing down their histories.The matrix is composed of the artifact's surrounding sediments, ecofacts, and characteristics. The rock, sand, gravel, or soils around the object or feature may contain crucial information.

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?.
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

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.

The intertropical convergence zone may be found as far as ________ north of the equator in july.
The intertropical convergence zone may be found as far as 25° north of the equator in July.
What is real about the convergence zone between the tropics?
The Inter Tropical Convergence Zone, often known as the ITCZ, is a low-pressure area that rounds the Earth generally close to the equator and is the meeting point of the trade winds from the Northern and Southern Hemispheres. It is characterized by convective activity, which frequently results in intense thunderstorms over wide swaths of terrain.
How does the location of the intertropical convergence zone ITCZ change over time?
The position of the ITCZ varies seasonally because it tracks the sun. In the summertime of the Northern Hemisphere, it goes north, while in the wintertime, it moves south. As a result, the tropics' wet and dry seasons are caused by the ITCZ.

What typically happens to the size, shape, and sorting of clasts as they are transported from steep mountains toward more gentle settings?
The clast become more rounded as they are transported from steep mountains toward more gentle settings.
The clasts make up 20-30% of rocks. Tumbles, bumps, and wear during transportation may reduce the size of the clast, increase its roundness, and cause the clast to be sorted by size. As sediments are transported and deposited, they leave evidence of modes of transport and deposition.
For example, when a vehicle slides down a slope, the resulting sediments are generally chaotic and have varying grain sizes. Grain size and the interrelationship between particles gives the resulting sediment texture. Clasts are classified by density based on the energy of the transport medium. High-energy currents can transport larger fragments. As the energy decreases, heavier particles are deposited and lighter debris is transported further.

In most of the continental US, only a third of runoff transfers the continental surplus to balance the deficit of the ocean's fraction of annual precipitation.
Water Cycle and Surface RunoffThe physical geology and topography of the ground as well as meteorological conditions all have an impact on surface runoff. Only approximately a third of precipitation that falls on land drains into rivers and streams before being dumped back into the ocean. The remaining two-thirds either evaporate, transpire, or soak into the earth (infiltrate). Humans have the ability to redirect surface runoff for their own purposes.More and more of the natural environment is being replaced by impermeable surfaces, such as roads, homes, parking lots, and buildings, which decrease groundwater infiltration and hasten runoff to ditches and streams as more people inhabit the planet and as development and urbanization increase.To learn more about Surface Runoff refer to:

Option D. If mLC = 90, mLA = 42, and CA = 10, the equation that can be used to find AB is [tex]cosine 42 = \frac{10}{AB}[/tex]
How to find ABWe have to find the the way to solve the right angled triangle we have here.
We have the angle at point A.
We have to make use of SOH CAH TOA rule
We would use
Cosine = adjacent / hypotenuse
adjacent = the value 10
The hypotenuse is = AB. This is the sign that is facing the angle.
We would then have the equation to be
Cosine 42° = 10/AB
[tex]cosine 42 = \frac{10}{AB}[/tex]
We can proceed to find AB
To get the value of AB
AB cosine 42 = 10
AB0.7431 = 10
AB = 10/0.7431
