Answer 1

Answer:

The bending of space-time causes objects to move on a curved path and that curvature of space is what we know as gravity. Mathematically one can go backwards or forwards in the three spatial dimensions. But time doesn't share this multi-directional freedom.

Answers

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;

To many wolves to feed with less prey.To many wolves are going to want to fight for being the alpha in the pack.

A female has a brother who is color blind and a mother who is not.
What is the probability that the female is a carrier for the trait?

25%

100%

50%

0%

Answers

I’m pretty sure it’s a 50% chance since the colorblind mother has two kids and one of them has the trait.

25% is the probability that the female is a carrier for the trait. So, the correct option is (A).

What is Colourblindness?

Color blindness is defined as a reduced ability to differentiate between colors compared to the norm of normal human color vision. It is also called color vision deficiency (CVD) when a person is color blind, usually having difficulty distinguishing between certain colors such as yellow and orange, green and brown, pink and grey, or blue and green. Purple. These are typical of what is called "red-green color blindness".

The genes that can give red-green color blindness are passed on the X chromosome, although it is passed on the X chromosome, red-green color blindness is more common in males, causing males to inherit it from their mothers. There is only 1 X chromosome.

In the above case, if the mother is not colour blind but her son is color blind so, the probability for her daughter is 25%.

Thus, 25% is the probability that the female is a carrier for the trait. So, the correct option is (A).

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

Answers

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.

The pizza that you ate for lunch is being digested. Summarize what happens to it in your stomach.

Answers

Answer:

This is the one.. that i did when i was schooling.. I still hv it thank fully..

Explanation:

The correct answer about the digestion in the stomach of the pizza one eats is - The pizza is churned, mixing with digestive enzymes and gastric acid.

Digestion of the food takes place in the alimentary canal or digestive system. In this organ system different organs are used to digest different food molecules and absorbs them.

Let assume you ate a pizza slice in which it moves through the alimentary canal. it begins from the mouth and ends at colon through the esophagus, stomach, small intestine, large intestine.

Mouth: here pizza is chewed with our teeth, broken down and mixed with our saliva. Saliva also has an enzyme, called amylase, to help break down carbohydrates. This called bolus that moves to the esophagus to stomach.Stomach: a pouch shape organ where the pizza mixes it with gastric juice and digestive enzymes to digest protein by pepsin. The food or pizza now called the Chyme that moves to small intestine.Small intestine: receiving the pizza in the small intestine, pancreatic juices and bile from the gallbladder mixed with it and digest the pizza.The nutrients from the chyme (the pizza) absorbed in the small intestine.

Thus, the correct answer is - The pizza is churned, mixing with digestive enzymes and gastric acid.

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.
