What is the difference between the muscle in your heart and the muscles in your hand?

Answer:

The muscle that makes up the heart is called the cardiac muscle. It is also known as the myocardium. The thick muscles of the heart contract to pump blood out and then relax to let blood back in after it has circulated through the body. The interossei muscles begin between the bones of the hand. There are four dorsal and three palmar interossei muscles. While all interossei bend the MCP joints, the dorsal interossei allow us to spread our fingers away from each other. The palmar interossei pull our fingers together.

Answer:

i hope it is use full to you

Explanation:

Cardiac muscle makes up the wall of the heart and is responsible for the forceful contraction of the heart. Smooth muscles make up the walls of the intestine, the uterus, blood vessels, and internal muscles of the eye. Skeletal muscles are attached to the bones and in some areas the skin (muscles in our face).

Answer:

Explanation:

A sequence of flowing lava, pyroclastic flows, volcanic eruptions, caldera-forming events, and earthquakes changed the landscape of Yellowstone forever. The pressure exerted by the magma chamber has resulted in measurable ground deformation in certain parts of Yellowstone known as resurgent pressure domes.

Fire Activity also causes the Yellowstone to change. As the number of very large wildfires and total acres burned annually increases, there is an increasing frequency of warm spring and summer temperatures, reduced winter precipitation, and early snowmelt in the Western United States during the last 20 years.

In 1995, the wolf population increased in Yellowstone, causing the deer population to decrease and to change their behavior. When threatened by wolves, deer graze less and move about to aerate the soil.

In the 70 years since the wolves left Yellowstone, the entire ecosystem had collapsed into chaos, with coyotes running riot, and elks overgrazing willows and aspens. Without those trees, songbirds declined, beavers could not build their dams, and riverbanks eroded.

Which organism created all usable food energy on Earth​
Zigmanuir [339]

Answer:

The Sun

Explanation:

The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.

RNA primers in Okazaki fragments are usually very short, less than 10 nucleotides and sometimes as short at 2 nucleotides in len
bagirrra123 [75]

Answer:

During DNA replication each parental DNA strand serves as a template to a new complementary strand. DNA polymerase is the main enzyme responsible for this process, it catalyzes the addition of nucleotides to form the new DNA chain.  

The complementary nature of the DNA strands, presents a difficulty for DNA replication: DNA polymerase catalyzes the polymerization of DNA only in the 5’ to3’ -in the leading DNA strand. Thus, the opposite DNA strand, the lagging strand, faced an obstacle that is solved by the Okazaki small fragments. The primase enzyme synthesizes small RNA fragments complementary to the lagging DNA strand. These RNA fragments serve as primers for the DNA polymerase. To remove this RNA primers and form a continuous complementary lagging strand, RNase H and DNAse ligase will further cut and join the DNA again.  

DNA polymerase has a higher processivity than primase, if processivity is the average number of nucleotides that it is capable to continuously add to the template strand. Primase dissociates from the template often during DNA replication as it has to constantly add new RNA primers to the strand.
