2. Coastlines are continually eroded by what
process? sc.6.E.6.2
A longshore currents
B parallel shore currents
C shortshore currents
D perpendicular shore currents
???????????
Answers
Coastlines are continually eroded by longshore currents, which are currents that flow parallel to the shoreline. These currents can be caused by the wind and waves, and they can transport sediment (such as sand and gravel) along the coast. As the sediment is moved and deposited, it can cause the coastline to change shape and erode over time.
Answer:
Explanation:
Coastlines are continually eroded by longshore currents.
Longshore currents are ocean currents that flow parallel to the shoreline. They are created when waves approach the shore at an angle, and the water is deflected by the friction of the bottom and the shape of the coastline. The resulting current flows parallel to the shore, and can cause erosion of the coastline over time.
Parallel shore currents and shortshore currents are not correct terms. Perpendicular shore currents are not a natural phenomenon and do not occur in the real world.

d) What happens to a microscope if place at the edge?
Answers
When the object is placed on the slide and is in focus for each objective, the space between the slide and the objective lens gets reduce, so the microscope shouldn't be set exact at the edge.
As the objective magnification increases, the working space also increases. Therefore, you need to change it to a higher power target.
Change the focus knob to increase the stage as you look at the objective lens and stage from the side. Without permitting the objective to make contact with the coverslip, increase it as high as it can go. The sample's focus or the condenser and light intensity might need to be arranged.
Thus the accurate way to focus is that adjustments need to be made effectively and smoothly

The ostrich is a bird. However, it has traits that are different from those of the birds we typically see flying around our neighborhoods. Using credible sources, investigate the environment and adaptations of ostriches to explain how they evolved to survive in their environment.
Answers
Answer:
According to National Geographic, ostriches are a part of a very small group of birds that cannot fly because unlike most birds, their small wings are not strong enough to carry their body for flight and their breastbone isn't balanced enough for flying. Birds that are unable to fly are called ratites.
A number of scientists namely Thomas Huxley, Richard Owen, and others have tried to show that these ratites are actually related to each other and eventually, it was discovered that they all had one thing in common, the way the bones at the roof of the mouth were arranged was similar to that of reptiles rather than other birds.
Richard Owen found and assembled the remains of an extinct ostrich skeleton which was an extinct moa and contrary to already held opinion, one ratite known as tinamous did not really fit with the profile of a ratite because it could fly, even though almost grudgingly and they possessed keeled sternum which suggests that they evolved from flying birds.
DNA tests showed that tinamous evolved within ratites and not necessarily as a separate entity. The tests also showed that moas and tinamous are related.
It was also speculated that the division of the supercontinent Pangaea southern side led to the separation of flightless ratite ancestors, causing each landlocked group to evolve and become the flightless birds we know today such as the ostrich, rheas, etc.
Answer:
An ostrich is an extremely large bird that lives in Africa. It can’t fly, but it has powerful legs that allow it to outrun most predators. Its flexible knees and two-toed feet enable it to run easily. An ostrich has strong leg muscles that it can use to kick large predators. It has claws on its wings to defend itself from predators and thick feathers to keep it warm at night. Ostriches have thick eyelids that protect their eyes from sandstorms.

When do brown parents produce white offspring?
Answers
If both parents are carriers of a recessive gene for white color, they may produce white offspring if the gene is inherited by the child from each parent.
A carrier is a person who carries a gene mutation for a particular disease or condition but does not necessarily display any symptoms of the disease.
Carriers usually have one normal gene and one mutated gene, and the normal gene is usually enough to prevent the development of the disease.
If both parents carry a recessive gene for white colour, their offspring may be white if the gene is inherited in child from both parents.
If the parents are not entirely brown but have some genetic diversity, this scenario is more likely.
Thus, it is important to understand that skin colour is a complex trait that is influenced by multiple genes rather than being determined by a single gene.

Where did people first settle?
Answers
Early settlements emerged in Mesopotamia (Iraq), Nile Valley (Egypt), Indus Valley (Pakistan/India), Yellow River (China), and Mesoamerica (Mexico/Guatemala/Honduras), fostering civilizations through agriculture, trade, and cultural development.
People first settled in various regions around the world, with the exact locations differing depending on factors such as climate, resources, and geographical features. Here are some examples of early settlements: 1. Mesopotamia: One of the earliest known settlements can be found in Mesopotamia, located in present-day Iraq. The fertile land between the Tigris and Euphrates rivers allowed for agricultural development, leading to the rise of ancient civilizations such as Sumer, Babylon, and Assyria. 2. Nile Valley: In ancient Egypt, people settled along the Nile River. The river provided fertile soil for agriculture and facilitated transportation and trade. The Nile Valley became the cradle of one of the most enduring civilizations in history. 3. Indus Valley: Another significant early settlement was in the Indus Valley, encompassing parts of modern-day Pakistan and India. The Harappan civilization, with its advanced urban planning and drainage systems, thrived in this region. 4. Yellow River: In China, people settled along the Yellow River (Huang He). The river's fertile floodplains supported agriculture, and ancient Chinese civilizations like the Xia, Shang, and Zhou dynasties emerged in this area. 5. Mesoamerica: In the Americas, early settlements arose in Mesoamerica, including the Olmec, Maya, and Aztec civilizations. These civilizations settled in areas such as modern-day Mexico, Guatemala, and Honduras, where they developed sophisticated agricultural practices and built impressive cities. It's important to note that these examples represent only a fraction of the various places where people first settled.

Tremendous amounts of water flow steadily over Niagara Falls, which straddles the border of New York and the Canadian province of Ontario. The water moves at speeds ranging from 2 to 3 feet per second. Over time, what will most likely happen to the rock wall behind the falls?
Answers
Explanation:
Given details=
Water flowing at the pace of 2 to 3 feet per sec
It must be understood that flowing water act as an erosive agent here.
As the water flows, it carries with itself erosive tools which erode the rock surface. Since the speed of water is considerable, the erosion is quite significant. Due to the erosive action of the river, the rock wall would be continuously eroded starting from the tip and in turn, would recede backwards (in the upstream direction).
The water will weaken the rock wall. Therefore, the wall will gradually crumble or wear away.

Answers
Methods that are used to control weeds in turf are topdressing, propane flamers, aeration, limiting summer irrigation, and vacuuming, while other options are more commonly used in agricultural or horticultural settings.
Propane flares use controlled flames to heat and kill weeds. The intense heat applied to grass damages the cells, destroying them. This technique is commonly used in organic weed control programs. Aeration is the creation of small holes or water features in the turf to improve soil structure, increase oxygen circulation, and also reduce compaction. Aeration can help control weeds indirectly by promoting healthy weeds, and can outcompete weeds and reduce their stand.
