Answer: Muscles work with bones by contracting and tugging on the bones and help the bones move, enabling various actions including standing, walking, running, and gripping objects.
Explanation:
The musculoskeletal system supports the body and enables locomotion in humans and many other animal species. The musculoskeletal system of the body is made up of the bones (the skeletal system), muscles (the muscular system), cartilage, tendons, ligaments, joints, and other connective tissue that supports and holds tissues and organs together.
By contracting and tugging on the bones, the muscles help the bones move, enabling various actions including standing, walking, running, and gripping objects. Different bones are joined together by joints to permit motion. In these joints, connective tissues bind bones to one another and to muscle fibers (tendons and ligaments). The bone ends are shielded from direct contact by cartilage. To move the bone linked at the joint, muscles contract.

How are ATP and ADP related? What are their functions?
The ATP molecule splits off one of its three phosphates when a cell has to expend energy to complete a task, resulting in the formation of ADP (Adenosine di-phosphate) + phosphate.
That phosphate molecule's energy is no longer bound to it and can now be used by the cell to perform tasks. Energy is released and ATP is changed into adenosine diphosphate when one phosphate group is removed by breaking a phosphoanhydride bond during a procedure known as hydrolysis (ADP).
As with the removal of a phosphate from ADP to create adenosine monophosphate, energy is likewise released (AMP). Adenosine diphosphate (ADP) is a chemical that transfers and supplies energy to cells. The primary energy molecule that cells need to power their processes is adenosine triphosphate (ATP). The phosphate bonds between them contain energy.

describe how a protein is made starting with the creation of rna. in your answer be sure to include the following words: DNA, mRNA, tRNA, rRNA, transcription (or transcribe), translation (ot translated), codon, anticodon, amino acid, nucleus, cytoplasm, protein, ribosome.
Protein synthesis involves the transcription of DNA into mRNA and then the translation of the mRNA into a protein. The process begins in the nucleus, where DNA is transcribed into mRNA. This process is catalyzed by RNA polymerase, which reads the DNA sequence and generates a complementary mRNA sequence. The mRNA then leaves the nucleus and travels to the cytoplasm.
In the cytoplasm, the mRNA is read by ribosomes, which consist of rRNA and protein. The ribosome reads the mRNA sequence in groups of three nucleotides called codons. Each codon specifies an amino acid, which is added to the growing protein chain.
tRNA molecules, which are specific to each amino acid, bring the amino acids to the ribosome. The tRNA molecule has an anticodon that is complementary to the codon on the mRNA. This ensures that the correct amino acid is added to the protein chain.
The process of translation continues until the ribosome encounters a stop codon on the mRNA. At this point, the protein is complete and it is released from the ribosome. The protein then folds into its three-dimensional structure, which is essential for its function.
Overall, protein synthesis is a complex process that involves the transcription of DNA into mRNA, the translation of mRNA into protein, and the interaction of tRNA and ribosomes to ensure the correct amino acid sequence. The resulting protein is crucial for the function of the cell and the organism as a whole.

climate systems quick check which of these is one of the milankovitch cycles?
One of the Milankovitch cycles is the change in the Earth's axial tilt. The angle between the Earth's rotating axis and its orbital plane around the sun is referred to as the axial tilt.
The axial tilt of the Earth fluctuates throughout time as a result of a variety of reasons, including the gravitational pull of other celestial bodies such as the moon and planets. These changes occur on a 41,000-year cycle and can have significant influence on the Earth's climate.
The seasonal changes between summer and winter can be more intense when the Earth's axial tilt is greater (i.e. the angle of tilt is greater). This can lead to more intense and long-lasting glacial, as well as greater temperature disparities between the poles and the equator.
When the Earth's axial tilt is lower, the seasonal changes between summer and winter are less severe. This may result in milder glacial episodes and more consistent temperature patterns over the world.

why did antonie van leeuwenhoek name bacteria bacteria??????
Antonie van Leeuwenhoek was a Dutch microbiologist who is considered the father of microbiology. He was the first person to observe and describe bacteria under the microscope in the 17th century. At the time, he did not have a complete understanding of the nature of these microorganisms and did not know that they were responsible for many diseases.
Van Leeuwenhoek referred to these tiny organisms as "animalcules" or "little animals" because of their movement. Later on, the French scientist, Louis Pasteur, suggested the term "microbe" for bacteria and other microscopic organisms. The word "bacteria" is derived from the Greek word "bakterion," meaning "small rod."
It is not clear why van Leeuwenhoek chose the name "bacteria" to describe these microorganisms. It may be that he used the term because he observed that many of these microorganisms were rod-shaped under the microscope. Additionally, he may have used the term to distinguish bacteria from other microorganisms he observed, such as fungi and protozoa.
