Answer:
C
Explanation:
this is because that Carbon 12 has 6 protons and electrons and the same goes for Carbon 14 so Choice A and choice B can't be answers so D and E arent equivalent too that means Choice C can be the appropriate answer.
further more explanation:
it's also Choice C because both carbon atoms are neutral which means that the number of protons and the number of electrons are the same so that leaves us with neutron and we get the neutron number by subtracting the mass number with the proton number so let's go on shall we!
for carbon 12= 12-6=6
for for carbon 14=14-6=8 which means the best alternative is Choice C.
Best of luck!!!
what is the values of pOH 0.020M HNO3
Answer:
pOH is 12.3
Explanation:
let's first get the pH of nitric acid:
[tex]{ \sf{pH = - log[H {}^{ + } ]}}[/tex]
but:
[H†] = 0.020 M
therefore:
[tex]{ \sf{pH = - log(0.020) }} \\ { \sf{pH = 1.7}}[/tex]
but, pOH = 14 - pH
[tex]{ \sf{pOH = 14 - 1.7}} \\ { \sf{pOH = 12.3}}[/tex]

Week 1: Bones, Muscles, and Joints
You are at a sports complex that has several events going on to include soccer, lacrosse, basketball and football. As you walk
around and stop at the different games you spot different incidents occur that require the player t leave the field. These
include a player holding there arm/shoulder, one unable to put weight on their foot/leg, one holding the area around the
buttucks/upper thigh, one is holding the side of his head, and one is holding there stomach/side. Knowing what you know now
about the bones, muscles and joints discuss in detail, what bones, muscles or joints are in these areas and what type of
diagnostic technique could be used?
Answer:
HI :)
Explanation:
What Are Bones and What Do They Do?
Bones provide support for our bodies and help form our shape. Although they're very light, bones are strong enough to support our entire weight.
Bones also protect the organs in our bodies. The skull protects the brain and forms the shape of the face. The spinal cord, a pathway for messages between the brain and the body, is protected by the backbone, or spinal column. The ribs form a cage that shelters the heart and lungs, and the pelvis helps protect the bladder, part of the intestines, and in women, the reproductive organs.
Bones are made up of a framework of a protein called collagen , with a mineral called calcium phosphate that makes the framework hard and strong. Bones store calcium and release some into the bloodstream when it's needed by other parts of the body. The amounts of certain vitamins and minerals that you eat, especially vitamin D and calcium, directly affect how much calcium is stored in the bones.
Bones are made up of two types of bone tissues:
Compact bone is the solid, hard outside part of the bone. It looks like ivory and is extremely strong. Holes and channels run through it, carrying blood vessels and nerves.
Cancellous (pronounced: KAN-suh-lus) bone, which looks like a sponge, is inside compact bone. It is made up of a mesh-like network of tiny pieces of bone called trabeculae (pronounced: truh-BEH-kyoo-lee). This is where bone marrow is found.
In this soft bone is where most of the body's blood cells are made. The bone marrow contains stem cells, which produce the body's red blood cells and platelets, and some types of white blood cells. Red blood cells carry oxygen to the body's tissues, and platelets help with blood clotting when someone has a cut or wound. White blood cells help the body fight infection.
Bones are fastened to other bones by long, fibrous straps called ligaments (pronounced: LIG-uh-mentz). Cartilage (pronounced: KAR-tul-ij), a flexible, rubbery substance in our joints, supports bones and protects them where they rub against each other.
How Do Bones Grow?
The bones of kids and young teens are smaller than those of adults and contain "growing zones" called growth plates. These plates consist of multiplying cartilage cells that grow in length, and then change into hard, mineralized bone. These growth plates are easy to spot on an X-ray. Because girls mature at an earlier age than boys, their growth plates change into hard bone at an earlier age.
Bone-building continues throughout life, as a body constantly renews and reshapes the bones' living tissue. Bone contains three types of cells:
osteoblasts (pronounced: AHS-tee-uh-blastz), which make new bone and help repair damage
osteocytes (pronounced: AHS-tee-o-sites), mature bone cells which help continue new born formation
osteoclasts (pronounced: AHS-tee-o-klasts), which break down bone and help to sculpt and shape it
What Are Muscles and What Do They Do?
Muscles pull on the joints, allowing us to move. They also help the body do such things as chewing food and then moving it through the digestive system.
Even when we sit perfectly still, muscles throughout the body are constantly moving. Muscles help the heart beat, the chest rise and fall during breathing, and blood vessels regulate the pressure and flow of blood. When we smile and talk, muscles help us communicate, and when we exercise, they help us stay physically fit and healthy.
Humans have three different kinds of muscle:
Skeletal muscle is attached by cord-like tendons to bone, such as in the legs, arms, and face. Skeletal muscles are called striated (pronounced: STRY-ay-ted) because they are made up of fibers that have horizontal stripes when viewed under a microscope. These muscles help hold the skeleton together, give the body shape, and help it with everyday movements (known as voluntary muscles because you can control their movement). They can contract (shorten or tighten) quickly and powerfully, but they tire easily.
Smooth, or involuntary, muscle is also made of fibers, but this type of muscle looks smooth, not striated. We can't consciously control our smooth muscles; rather, they're controlled by the nervous system automatically (which is why they're also called involuntary). Examples of smooth muscles are the walls of the stomach and intestines, which help break up food and move it through the digestive system. Smooth muscle is also found in the walls of blood vessels, where it squeezes the stream of blood flowing through the vessels to help maintain blood pressure. Smooth muscles take longer to contract than skeletal muscles do, but they can stay contracted for a long time because they don't tire easily.
Cardiac muscle is found in the heart. The walls of the heart's chambers are composed almost entirely of muscle fibers. Cardiac muscle is also an involuntary type of muscle. Its rhythmic, powerful contractions force blood out of the heart as it beats.

European frog's-bit is a free-floating plant with clustered heart-shaped leaves. Resembling small water lilies, frog's bit has white flowers with three petals and yellow centers that bloom in the summer. European Frog's-bit is native to Europe but was introduced to North America in the 1930s as an ornamental pond plant. It is one of eleven invasive aquatic species identified in Maine law as illegal to import, sell, and transport. What is a way to prevent its spread in Maine lakes and ponds?
Answer:
The correct answer is - D) Educational outreach and watercraft inspections at boat ramps to keep infestation from migrating from one water body to another.
Explanation:
I just did the USA Test Prep and this is the correct answer! Hope this is helpful!!! Please up vote to help others!
The main reason for the spread of European frog's bit in Maine lakes and ponds is by boats and wildlife.
What do you mean by Invasive Species?Invasive species may be defined as species that cause ecological or economic harm in a new environment where it is not native.
Invasive species are prevented to spread in order to reduce their effect on ecological as well as economic points of view.
The best way to prevent the spread of European frog's bit is to spread awareness of its harm through educational outreach, banned their migration at the international level, and always remove visible mud and plants before leaving a water body.
Therefore, it is well described above.

Explanation:
Fracking uses highly pressurized fluids, such as water mixed with sand and chemicals, to drive open cracks that exist in underground rock. Which
statement best describes an environmental consequence of this process?
• Chemicals added to the liquid can contaminate groundwater.
O Wastewater is contaminated with oil and becomes sludge in landfills.
Water vapor is released into the air, which is considered a greenhouse gas.
Heavy metals are released into surrounding soil, poisoning local vegetation
The correct answer is that chemicals added to the liquid can contaminate groundwater.
Fracking is a method of drilling fossil energy resources, which requires a lot of water and consumes local water resources. It is pumped with high pressure water, sand and chemicals, causing high pressure to block the porous rock and release gas.
The water spill itself destroys nature from the drilling site, and may even cause earthquakes, especially due to the pumping of abundant wastewater into porous rock types such as limestone. For example, Oklahoma appears to have become a special earthquake risk area. The biggest impact of water distortion is on groundwater. In Wyoming, USA, the same chemicals found in groundwater have been found in groundwater, and some of them are toxic or carcinogenic.

Answer:
below
Explanation:
It's not necessarily that a large forest can only have a small population of wolves because a larger population will not affect the ecosystem that much but it just depends on the area. One forest may have more prey than others which the wolves rely to eat and stay healthy. So yes it would be preferred to have a smaller population but again, it doesn't hurt to have a large one either. The main problem with having a larger population of wolves can be one of two issues;
