Why should muscles not be dissected at the points of origin and insertion
Answer:
The muscles should not be dissected at the points of origin and insertion due to the fact that the cell structures present here are a typical in nature .
Explanation:
The origin is where the muscle joins the stationary bone. The insertion is where it joins the moving bone. ... At the bone, the fibres of the tendon are embedded in the periosteum of the bone. This anchors the tendon strongly and spreads the force of the contraction, so the tendon won't tear away easily.
Which evidence from the Hershey-Chase experiment demonstrated that DNA, not protein, is the genetic material
Answer:
The evidence from the Hershey-Chase experiment demonstrated that DNA, not protein, is the genetic material DNA contains phosphorus, but protein does not was as result of some analysis in which it was discovered that Protein contains sulfur and DNA does not.
This was what led to the use of radioactive phosphorus and radioactive sulfur in self-identification.

Which factor most affects the order of amino acids in a protein? (3.1.2) Group of answer choices the DNA located in the nucleus of the cell the cell in which the protein is located the amount of ATP available for the cell’s use the area in a cell where proteins are produced
Answer options:
The DNA located in the nucleus of the cell The cell in which the protein is located The amount of ATP available for the cell’s use The area in a cell where proteins are producedAnswer:
The DNA located in the nucleus of the cell
Explanation:
The sequence of the DNA is transcribed into a messenger RNA (mRNA). The mRNA molecule is translated into a sequence of amino acids. Every 3 nucleotides in the mRNA represents a codon. These codons correspond to a complementary anticodon linked to a tRNA, which specifies the order of amino acids in a protein.
Carbohydrates are a type of biological macromolecule required to carry out life functions. Which of the following is NOT true regarding carbohydrates?
A. Monomers of starch are sugars such as glucose.
B. Living things store extra sugars as complex carbohydrates.
C. They contain carbon, hydrogen and oxygen, usually in the ratio of 1:2:1.
D. Carbohydrates are the main component that makes up cell membranes
Answer:
D. Carbohydrates are the main component that makes up cell membranes
Explanation:
The main component of the cell membrane is a double layer of phospholipids - molecules with a phosphate head and fatty acid tail. Therefore D is incorrect. There are some carbohydrates in the cell membrane, but they are not the main component.
The statement 'carbohydrates are the main component that makes up cell membranes' is NOT true (Option D).
Carbohydrates are biopolymers composed of monosaccharide units linked by glycosidic bonds.Complex carbohydrates (e.g., starch) consist of large branched or unbranched chains of monosaccharides, while simple carbohydrates (e.g., glucose) are monosaccharides.Complex carbohydrates serve as sources of longer energy storage for the cells, while monosaccharides provide energy quickly.The main component of the cell membranes are lipids (i.e., phospholipids and cholesterol).In conclusion, the statement 'carbohydrates are the main component that makes up cell membranes' is NOT true (Option D).

Hello!!! Princess Sakura here ^^
Explanation:
First things first if we are going to form a hypothesis it doesn't matter if it is correct hypothesis are supposed to get tested.
So anyways....
I believe that the solubility of oxygen will decrease as the temperature increase.
I believed that because as temperature increases molecules start to move faster and move farther away from each other.
Temperature can have a significant impact on the concentration of oxygen in various environments. 1) Solubility of Gases, Oxygen Dissociation, Biological Processes.
Here's a step-by-step explanation of how temperature affects oxygen concentrations:
1. Solubility of Gases: The solubility of gases, including oxygen, in a liquid like water is affected by temperature. Generally, as temperature increases, the solubility of gases decreases. This means that at higher temperatures, less oxygen can dissolve in water or any other liquid.
2. Oxygen Dissociation: In the context of the human body, temperature affects the dissociation of oxygen from hemoglobin in red blood cells. As temperature increases, the affinity between oxygen and hemoglobin decreases. This means that oxygen is more readily released from hemoglobin and made available to tissues and organs. Conversely, as temperature decreases, the affinity between oxygen and hemoglobin increases, making it more difficult for oxygen to be released.
3. Biological Processes: Temperature also affects the metabolic rates of organisms. Generally, as temperature increases, metabolic rates increase, leading to higher oxygen consumption. For example, in aquatic ecosystems, warmer water temperatures can enhance metabolic rates of aquatic organisms, leading to increased oxygen demand. Conversely, lower temperatures can slow down metabolic rates and reduce oxygen demand.
It's important to note that the specific effects of temperature on oxygen concentrations can vary depending on the system or environment being studied. Different factors such as pressure, salinity, and the presence of other substances can also influence the relationship between temperature and oxygen concentrations.

When the isotonic saline solution described in part A is connected to an unknown solution via a semipermeable membrane, the unknown solution level drops. Based on this information, what can be said about these two solutions?
Answer:
The new solution has a higher concentration than the isotonic saline solution
Explanation:
Here, we want to deduce what has happened in the question.
We are told that the level of the isotonic saline solution dropped because it was connected an unknown solution using a semipermeable membrane.
Since the level of the solution dropped, then it must have occurred that there has been the loss of some of the molecules of the solution.
What has occurred is the process of Osmosis
Osmosis simply involves a movement through a semipermeable membrane of solvent molecules due to the fact that the previous solution is of lower concentration than the present one.
So what we can see here is that there has been a movement due to osmosis as a result of the fact that the new solution has a higher concentration than the former one

Various cultures designate racial categories differently, and they often base these categories on very different traits. For example, some cultures use nose shape as one of the defining traits for a racial group. Other cultures do not use nose shape in defining racial groups, but use hair color instead. Conduct a survey in person on your campus, via social media accounts online, or among your friends and family. Ask at least 20 people what five traits they think are most important when distinguishing racial groups. Document the responses, and then review the data. Did every person use the same traits? What do differences in racial classification such as these suggest about the universality of race and racial groupings?
Answer:
In the clarification segment below, the definition of the query has been mentioned.
Explanation:
This shows that perhaps the distinctions between individuals living in a culture or geographical region are often based on ethnicity and ethnic groupings. A single population belonging to a specific geographical region has been shown to possess many characteristics, including hair texture, individual capacity for heat resistance, and food taste. Throughout certain races or ethnic groups, these similar traits bring them together. The young government corresponding to a certain race is often asked to follow the custom adopted by those belonging to a certain particular demographic. It is assumed that persons belonging to that same race follow these rituals mostly to solve difficulties they have experienced personally due to errors perpetrated by certain ancestors.help plz i will do anything

nucleus.
Answer:
Nucleus
Nuclear pore
Proton pump
Cyt C Ribosome
Explanation:
The nucleus of the cell is the largest of all of these structures, all of the others are located inside the nucleus of the cell or interact with it, the nuclear pore is a pore in the nucleus that allows the transport of proteins through the membrane, the proton pump passes through the nuclear pore, and a Ribosome is a protein that transports nutrients, so that would be the smallest.
The order from largest to smallest is nucleous>> >> ribosome >> nuclear pore >> proton pump >> Cyt C.
The nucleus is the organelle that contains the genetic material in a eukaryotic cell, whereas ribosomes are protein factories.The nuclear pore is a structure that allows the passage of certain molecules between the cytoplasm and the nucleus.The proton pump is an integral protein-membrane, whereas Cyt C is a mitochondrial protein.In conclusion, the order from largest to smallest is nucleous>> >> ribosome >> nuclear pore >> proton pump >> Cyt C.

How would you improve food safety from a food supplier standpoint (farmer, factory, production, distribution, food scientists) be very specific with your answer and make sure to use facts to justify why you believe the way you do. The explanation must be at least three paragraphs (5-8 sentences)
Answer:
Foods are the basic building blocks of living things, yet they may pose a threat and become harmful to human health in some situations [13]. Many people throughout the world become ill because of the food they eat. These diseases associated with food consumption are referred to as foodborne diseases, and they may result from dangerous microorganisms [14]. Foods can become harmful to human health or even fatal when combined with bacteria, mold, viruses, parasites and chemical toxins [13]. Therefore, it is absolutely necessary that consumers be provided with a safe food supply. The factors involved in the potential threat caused by foods are inappropriate agricultural practices, poor hygiene at any stage of the food chain, lack of preventive controls during processing and preparation of the food, incorrect use of the chemical materials, contaminated raw materials, food and water and inappropriate storage [15].

Explain how horned toads squirting blood from their eyes is a particularly good defense against coyotes.
Answer:
A stream of nasty-tasting blood squirts from the toads eyes, straight into the coyote's mouth. The coyote steps back, shaking its head from side to side in disgust. It retreats, wiping its muzzle, while the uninjured toad skitters away to safety.
Answer:
Horned toads squirting blood from their eyes is a good defense against coyotes because squirrels are much smaller than coyotes so they can't fight back. The blood scares the coyotes and makes them run away so that the squirrel can survive.
