the action potential on the muscle cell leads to contraction due to the release of calcium ions. where are calcium ions stored in the muscle cell? view available hint(s)for part f the action potential on the muscle cell leads to contraction due to the release of calcium ions. where are calcium ions stored in the muscle cell? terminal cisterns (cisternae) of the sarcoplasmic reticulum cytosol sarcolemma t tubule
The correct answer is sarcoplasmic reticulum cytosol sarcolemma t tubule terminal cisterns (cisternae).
The action potential invades T-tubules and opens L-type calcium channels, causing ryanodine receptors (RyRs) in the SR to open and release calcium, stimulating contraction. Calcium ions cause muscle contractions. In response to an action potential, the sarcoplasmic reticulum releases calcium ions, which bind to troponin on actin filaments and cause conformational changes that expose myosin-binding sites. Tropomyosin's tertiary structure is altered when calcium ions bind to it. As a result, tropomyosin moves away from actin-myosin binding sites, allowing cross bridges to form. Calcium ions also activate the enzyme ATP hydrolase, which hydrolyzes ATP and provides energy for contraction.

The locations for three genes have been added to this cartoon. For clarity, the locations have only been noted on one chromatid. The lowest frequency of crossovers would occur between genes a and b.
A cell generates a fresh copy of all of its DNA as it gets ready to divide, resulting in two copies of each chromosome in the cell. "Sister chromatids" refer to the two copies of the cell's original chromosome.
The two chromatids are torn apart during anaphase of cell division, and the chromatids are distributed among the cytoplasm of each daughter cell.
A vast quantity of DNA that is arranged physically into a single structure is called a "chromosome." Because of this, the "sister chromatids" are regarded as being separate chromosomes even though they are joined together. Each chromatid is thought to be its own chromosome once they are divided during anaphase.

Some plants thrive most in winter. An example is the winter wheat. Winter wheat and similar plants have evolved to tolerate extreme cold. specifically, the winter wheat plant can increase the percentage of unsaturated phospholipids in its membrane during the winter season. This helps the plant in that
What are unsaturated phospholipids?The plasma membrane is the membrane that surrounds all cells. They serve as a barrier between the cytoplasmic location and the cell's internal environment. Phospholipids make up the plasma membrane. This lipid bilayer is referred to as a biomembrane or living membrane. This bilayer has a variety of proteins and lipids that are embedded in it.
The unsaturated fatty acids in the membrane have double bonds known as kinks. This kink in the membrane inhibits the membrane from being tightly packed, which might cause the membrane to become rigid. Because the double bonds provide room between the phospholipids, this characteristic also plays a role in membrane fluidity. It will keep the molecule from freezing when the temperature drops.

Capillary sphincters are circular muscular walls that regulate blood flow through the capillaries.
Specialized cells known as muscle fibers make up the muscular system. Contractibility serves as their primary purpose. Movement is made possible by muscles that are affixed to bones, internal organs, or blood vessels. Muscle contraction produces the majority of body movement. The movement of cilia, the flagellum on sperm cells, and some white blood cells that move in an amoeboid manner are examples of exceptions to this rule. Simple movements like walking and running are produced by the coordinated action of joints, bones, and skeletal muscles. Skeletal muscles can also be seen moving in more subtle ways, which results in different face expressions, eye movements, and breathing patterns. They help with digestion, regulate respiration and heartbeat, and permit mobility. When you work out and eat well, your muscles flourish just like the rest of your body.

1. How might Margaret Mead have been biased by her culture and experience when she examined the culture of the Samoans?
2. Do you think any human universals appear in all cultures? Can you think of any universal taboos?
3. One of the main criticisms of Mead was that she did not use "science" in her approach to the study of Samoan people and culture. While she is also criticized for not spending enough time in Samoa to make a proper assessment, she used observation methods to come to her conclusions. Assess how effective you think observation is to the study of anthropology. In the case of Margaret Mead, do you think her observations were correct? Why or why not?
4. Why do you think Mead's own sexuality and identity were discussed in the article?
5. How can a researcher eliminate their own bias and subjectivity when they observe another culture? Won’t they always interpret what they see through the lens of their own experience and culture? Explain your thinking.
It is to be noted that the cited article is "Margaret Mead: Human Nature and the Power of Culture." See the explanation and answers below for further information.
How might Margaret Mead have been biased by her culture and experience when she examined the culture of the Samoans?Margaret Mead's examination of Samoan culture may have been influenced by her own culture and experience because:
Her perception of how adolescents should behave based on her environment and upbringing may have colored her observation and expected results. Note that it is insufficient to conclude by observing two cultures what a generally accepted behavior for adolescents should be.
There are universal taboos in human nature. According to Sigmund Freud, some of them are Cannibalism, incest, and patricide.
It is appropriate to assess the strength of Mead's arguments based on the methodology she employed to conduct her study. Science should be practical and realistic.
While observation is one approach to acquiring primary evidence, there is no way to tell if the Samoans were being nice because she was a tourist and so did not act as they would if she were not present.
In science, observations should be carried out in such a way that the population or sample being observed is not harmed while the observer stays unknown.
Mead's identity and sexuality were included in the piece since it was critical that the report on her own report be neutral. Although it is not stated directly, the information provided regarding Mead's sexuality offers the reader a sense of the probable factors that may have led to her being subjective, if at all.
Unless such a study is subjected to peer review, it cannot be guaranteed that certain components of subjectivity will not be present.
