Why are short bones well suited to an area like the wrist? Why are long bones more suited to areas like the lower arm?

Answers

Answer 1

Answer:

Short bones are well suited for the wrist because they provide stability, and long bones are well suited for the arm because they can support a lot of weight.

Explanation:

Bones have different shapes and lengths. The reason for this is that their design has a specific function in the body. One way to classify bones is according to their shapes, there are short bones, long bones, flat bones, and irregular bones.

Short bones are approximately equal in length, width, and thickness. They provide stability and some restricted movements, owing to this fact, they are present in our ankles and wrists so that we can stand straight and have proper support when we use our wrist to stabilize ourselves or hold to an object.

In long bones, the length predominates over thickness and width. They work as levers being able to support a lot of weight. This is why long bones are suited for the lower arm, when the arm muscles contracts they can lift heavy things, the same happens with the bones in our legs, they are long because they have to hold the weight of the body.

Which is a characteristic of diatoms?

Answers

Diatoms have two distinct shapes: a few (centric diatoms) are radially symmetric, while most (pennate diatoms) are broadly bilaterally symmetric. A unique feature of diatom anatomy is that they are surrounded by a cell wall made of silica (hydrated silicon dioxide), called a frustule.

Diatoms have two distinct shapes: a few (centric diatoms) are radially symmetric, while most (pennate diatoms) are broadly bilaterally symmetric.

What are Diatoms?

Any member of the vast group of several genera of microalgae that can be found in the world's oceans, streams, and soils is referred to as a diatom.

Diatoms can photosynthesize, which allows them to change the dissolved carbon dioxide in the water into oxygen.

For higher-ranking organisms in the food chain, like invertebrates and tiny fish, they serve as a major source of food. In the energy and nutrition cycles of water resources, diatoms can also be vital players.

Diatoms can be divided into two shapes: pennate diatoms, which make up the majority, are broadly bilaterally symmetric, and central diatoms, which make up the minority.

Thus, these are the characteristics of diatoms.

The diagram shows a transform fault. What is a likely result of slippage alongthis fault?FaultOA. Seismic

Answers

The diagram shows a transform fault and it is a likely result of slippage along this fault? is A. Seismic waves

A likely result of slippage along a transform fault is seismic waves (option A). A transform fault is a type of tectonic plate boundary where two plates slide past each other horizontally. As the plates move, stress builds up along the fault line, and when it exceeds the strength of the rocks, slippage occurs, releasing accumulated energy.

During the slippage, the rocks on either side of the fault quickly move relative to each other. This rapid movement generates seismic waves, which are vibrations that propagate through the Earth's crust. These seismic waves travel outward from the fault in all directions, causing ground shaking and vibrations.

Seismic waves are responsible for earthquakes, and their intensity and magnitude can vary depending on factors such as the amount of slippage, the depth of the fault, and the strength of the rocks involved. The seismic waves can result in ground shaking and can potentially cause damage to buildings, infrastructure, and human lives, depending on their magnitude and proximity to populated areas. Therefore, seismic waves are a likely result of slippage along a transform fault. Therefore, Option A is correct.

How would you explain the key concepts for the CWA in less than two minutes?

Answers

Answer:

Explanation:

vPoint Source - a source of water discharged to surface water through a discrete point - generally through a pipe, ditch, or channel.

Nonpoint Source - Nonpoint sources, such as parking lots or athletic fields, discharge runoff water to groundwater or surface water; runoff does not come from  a pipe, ditch, or channel. These sources may contain pollutants such as pesticides, motor oil, and soaps.

Navigable Waters of the United States  For the purposes of the Clean Water Act, the term "navigable waters" includes:

all waters used in commerce, including groundwater;

all interstate waters including wetlands, mudflats, and sand-flats; and

all other waters such as lakes, rivers, streams, wetlands and sloughs.

EPA policy states, "The majority of facilities in the U.S. have the potential to discharge to navigable waters."  The Supreme Court decision in (2006) requires the Army Corps of Engineers and the EPA to determine whether there is a "significant nexus" between a navigable waterway and an area a spill might affect.  In June of 2007, EPA and the Army Corps of Engineers released provisional interpretive guidance regarding the "significant nexus” question. According to this guidance, the agencies will assert jurisdiction over traditional navigable waters, wetlands adjacent thereto, and relatively permanent tributaries thereof. The agencies will generally not assert jurisdiction over swales and ditches that lack routine water flow. Finally, the agencies will apply the "significant nexus" requirement and make a case-by-case, fact-specific analysis on impermanent tributaries and other wetlands.

Additional executive orders were issued 2015 in 2019.  Under the 2019 proposal, traditional navigable waters, tributaries to those waters, certain ditches, certain lakes and ponds, impoundments of jurisdictional waters, and wetlands adjacent to jurisdictional waters would be federally regulated. It also details what are not "waters of the United States," such as features that only contain water during or in response to rainfall (e.g., ephemeral features); groundwater; many ditches, including most roadside or farm ditches; prior converted cropland; stormwater control features; and waste treatment systems.

Could the requirement for one or more NPDES Discharge Permit apply to my campus?

If your campus discharges pollutants directly to navigable waters of the United States through a point source, you must obtain an NPDES permit or redirect the flow of the waste.

Stormwater releases from certain activities require an NPDES permit. The most common activities on college campuses requiring NPDES permits for stormwater are construction activities disturbing more than 1 acre, hazardous waste storage areas operating under the Resource Conservation and Recovery Act permit system, steam-generating power plants, and airports. See Stormwater section below.

Regulations issued by local water authorities, or Publicly Owned Treatment Works (POTWs), not NPDES permits, govern discharges into sanitary sewer systems. See Sewer Use (POTW) section below for more information about requirements for using POTWs for commercial or industrial waste disposal.

What do I have to do related to NPDES Discharge Permits?

Determine where wastewater flows from buildings and processes on your campus. Any industrial or commercial operation (e.g., ice rink melt pits, floor drains, and vehicle wash stations) that discharge into a water of the United States may require an NPDES permit. If required, you must obtain such a permit from the appropriate regulatory agency, probably your state environmental agency.

French drains, dry wells, and septic system leach fields are different from point source discharges because they do not immediately affect surface water. Some state and federal environmental agencies manage these systems under the Underground Injection Control program, part of the Safe Drinking Water Act. See Safe Drinking Water Act for more information.

The term that best describes a white-tailed deer is "primary consumer." The correct answer is D

As a primary consumer, the white-tailed deer feeds directly on plants, such as leaves and grasses, which are producers in the ecosystem. Primary consumers are herbivores that obtain their energy and nutrients by consuming plant material.

They play a crucial role in transferring energy from the producers to higher levels in the food chain.

White-tailed deer are not predators because they do not hunt and consume other animals. They primarily rely on plant matter as their source of food.

They are also not secondary consumers, which are organisms that feed on primary consumers. In the context of the ecosystem, the white-tailed deer occupies the position of a primary consumer as it directly consumes plant material for sustenance and energy. Therefore, the correct answer is D.
