In the muscles of the limbs, the origin is usually the immobile muscle attachment. True
A skeletal muscle connects to bone (or other muscles or tissues) at two or more points. If the location is a bone that stays motionless during an activity, the connection is referred to as an origin. If the connection is on a bone that moves during the activity, it is referred to as an insertion.
Muscle tissue is classified into three categories in the muscular system: skeletal, cardiac, and smooth. The term "structural" refers to the fact that the body has a distinct structure. Skeletal muscle is responsible for the movement of bones and other structures. To pump blood, cardiac muscle contracts.

How does the Devil and Tom Walker reflect Puritans
"The Devil and Tom Walker" reflects the Puritan belief in the concept of predestination, which holds that God has already predetermined the fate of every individual and that salvation can only be attained by the elect, who have been chosen by God.
Tom's encounter with the devil can be seen as a reflection of the Puritan belief in the eternal struggle between good and evil, and the constant temptation of sin.
What does "The Devil and Tom Walker" show?"The Devil and Tom Walker" is a short story by Washington Irving that was published in 1824. The story also reflects the Puritan belief in the importance of hard work and the dangers of material wealth.
The story portrays Tom Walker as a greedy and miserly man who is only interested in accumulating wealth and power, and is ultimately punished by the devil for his greed and avarice. This reflects the Puritan belief that material wealth is a temptation that can lead one away from the path of salvation.
Therefore, "The Devil and Tom Walker" reflects many of the Puritan beliefs and values that were prevalent in New England during the late 1700s, including the concepts of predestination, the eternal struggle between good and evil, the dangers of material wealth, the importance of repentance and redemption.

Evidence that cytoskeletal elements have ancient origins comes from the: sequence similarities of cytoskeletal elements when comparing distantly related organisms. presence of cytoskeletal elements in both eukaryotes and prokaryotes. ability to form functional hybrid microfilaments from actin monomers taken from distantly related organisms. observation that both prokaryotes and eukaryotes use cytoskeletal elements to assist cell division. All of these choices are correct.
Answer:
All of these choices are correct.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Generally, cells have the ability to independently replicate themselves. In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles. Some examples of cell organelles in all living organisms such as trees, birds, and bacteria include; nucleus, cytoplasm, cell membrane, golgi apparatus, mitochondria, lysosomes, ribosomes, chromosomes, endoplasmic reticulum, vesicles, cytoskeleton, etc.
Cytoskeleton refers to a structure consisting of filaments and tubules which help to maintain internal organization and support the shape of the cells. It comprises of three (3) main filaments and these includes: actin filaments, intermediate filaments and microtubules.
Generally, there are numerous evidence that cytoskeletal elements have ancient origins and they include all of the aforementioned facts.

What precisely is reproduction?The process of creating offspring is called reproduction. The two basic types of reproduction are sexual and asexual. An creature that reproduces sexually is extremely varied and carries the genetic material of its two grandparents. Asexual reproduction, which involves each parent reproducing themselves, results in children that are genetically identical.
Explain it the action of procreating?The process of creating new members of same species is called reproduction. An organism has two ways of reproducing: asexually and sexually.

A gene for microtubule proteins is being made in a cell. How can mRNA represent an exact copy of that gene
A gene for microtubule proteins is being made in a cell. The mRNA representing an exact copy of that gene is put together using base pairing rules.
Gene expression is the process by which genetic information carried by DNA is converted from genes via messenger RNA to proteins.
mRNA is the molecule that links genes to proteins. The mRNA is formed through the process of transcription from a gene strand. The mRNA is then translated into protein by the joint action to transfer RNA and the ribosome.
mRNA therefore, serves as a temporary copy of information found in the DNA. Thus, mRNA represents an exact copy of the gene and it is put together using base pairing rules.

How does aneuploidy lead to cancer initiation?
Answer:
Chromosomal aberrations during cell division represent one of the first recognized features of human cancer cells, and modern detection methods have revealed the pervasiveness of aneuploidy in cancer. The ongoing karyotypic changes brought about by chromosomal instability (CIN) contribute to tumor heterogeneity, drug resistance, and treatment failure. Whole-chromosome and segmental aneuploidies resulting from CIN have been proposed to allow “macroevolutionary” leaps that may contribute to profound phenotypic change. In this review, we will outline evidence indicating that aneuploidy and CIN contribute to cancer evolution.
