The molecule which has likely been removed or mutated from a cell that can form beads on a string chromatin, but not solenoid fibers is: A. Η1
A cell can be defined as the fundamental functional, structural and smallest unit of life for all living organisms.
Genome editing refers to a high-tech process through which scientists remove (delete), replace or insert a deoxyribonucleic acid (DNA) sequence into the cells of a living organism such as an animal, bacterium, plant, etc., so as to improve on its physical and chemical conditions or correct a genetic disorder.
Chromatin can be defined as a complex form of deoxyribonucleic acid (DNA) and protein found in the cells of an eukaryotic organism.
In the classic model of chromatin, the beads simply refer to the nucleosomes while the string is simply the linker deoxyribonucleic acid (DNA).
Basically, the deoxyribonucleic acid (DNA) is wrapped around histone proteins to form nucleosomes and the beads on a string structure (euchromatin).
Furthermore, there exists a linker histone H1 in addition to core histones that reaches the entry or exit of the deoxyribonucleic acid (DNA) strand on the nucleosome.
In conclusion, a cell cannot form beads on solenoid fibers but it can form beads on a string chromatin because the H1 molecule has likely been removed or mutated in the cell.

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.Best of Luck!

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?
Answers
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.
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.
