Explanation:
When The Linear Form Of Glucose Cyclizes, The Product Is a(n):________. A) Anhydride. B) Glycoside. C) Hemiacetal. D) Oligosaccharide.
Answer:
Hemiacetal
Explanation:
The linear for of glucose that cyclizes is called Hemiacetal because it is a compound that is formed by attack of hydroxyl group when the carbon atom bind to hydroxyl group and also to aldehyde group or ether which is normally called anomeric carbon in carbohydrates, these therefore make the glucose to become cyclical and it is a six membered ring also called glucopyranose.
When the linear form of glucose cyclizes, the product Is a hemiacetal.
Glucose is a six membered sugar. It is a monosaccharide. The sugar can exist in either the linear or the cyclic form. The cyclic form of glucose exists as a hemiacetal.
The hemiacetal is formed by the attack of the hydroxyl group on carbon number 5 on the aldehyde group on carbon number 1.
Hence, when the linear form of glucose cyclizes, the product Is a hemiacetal.

Maggie's Plant Experiment In this exercise you will read the following scenario and identify the parts of the scientific method in it. Maggle read that some plants grow better if the soil is acidic. She can't believe that a plant can grow when exposed to acid. Maggle decides to test if the plants she has will grow better when acld is added to the soil. She puts potting soll in two planting containers and transplants two of her geraniums that seem about the same size into the pots. She puts the pots in the same location so that they both get the same sunlight each day, are at the same temperature and she makes sure they get the same amount of water. However, Maggie puts a tablespoon of vinegar in the water she gives to one of the plants. She measures the growth of the plants every week for five weeks and records the results in a data table below: Height of Plants in Container with Height of Plants in Container without Week Vinegar Vinegar (cm) (cm) 10.0 10.0 2 12.4 11.5 3 14.8 13.0 18.0 15.7 5 21.4 17.8
Answer:
Please find the identified steps of the scientific method below
Explanation:
A scientific method is a series of steps that aims at solving a problem. The steps in a scientific method include:
1. Making observation: In this experiment, Maggie observed when she read that some plants grow better if the soil is acidic. This is her observation that led to the scientific question: Do plants grow better in an acidic soil?
2. Formulating hypothesis: Hypothesis is a testable explanation to a problem. In this experiment, Maggie's hypothesis is; IF acid is added to the soil, THEN plants will grow better
3. Test hypothesis: the hypothesis is tested by conducting an experiment. In this case, Maggie places two geranium plants of the same size in two pots. Then she added a tablespoon of vinegar to one of the pots and allows the other grow normally without acid. The independent variable in this experiment is the vinegar added while the dependent variable is the height of the plants. The plant group with the vinegar is the experimental group while the plant group without vinegar is the control group. The constants of this experiment are same sunlight, same amount of water, same location etc.
4. Analyse data: The growth of the control and experimental plants were measured every week for five weeks by measuring their heights. The height (cm) of the plants with vinegar for the five weeks as as follows: 10.0, 12.4, 14.8, 18.0, 21.4 while the height in cm for the plants without vinegar for the five weeks is as follows: 10.0, 11.5, 13.0, 15.7, 17.8.
5. Conclusion: Based on the result, the plants exposed to vinegar grew better each week except week 1, which is the week they started. Hence, the hypothesis of this experiment will be ACCEPTED because the experiment proves it.
The scientific method parts in the scenario are: observation, research question, hypothesis, experimental design, data collection, data analysis, and conclusion.
The following scientific method components are depicted in the scenario:
Maggie reads that certain plants thrive in acidic soil and expresses her scepticism about this assertion.
Will adding acid to the soil help plants develop more effectively? Maggie asks in her research question.
Maggie's hypothesis, even if it isn't stated in the scenario, can be deduced as follows: The plants will grow more effectively if acid is introduced to the soil.
Design of the Experiment: For Maggie's experiment, potting soil is used to fill two planting containers, and two geraniums of the same size are transplanted into each container. She makes sure that both containers have the equal amount of water, sunlight, and temperature.
Data collection: Over the course of five weeks, Maggie measured the development of the plants once a week, and she recorded the heights of each plant in a data table.
Data comparison and analysis are done by Maggie using the plants' measured heights during a five-week period.
Maggie can make inferences about her hypothesis and whether the vinegar addition had an impact on the plants' growth based on the information she has gathered and the analysis she has done.
Thus, these are the parts of the scientific method in it.

Which type of protein is hemoglobin? Question 2 options: Contractile Structural Hormone Transport Question 3 (1 point) What are the building blocks of proteins? Question 3 options: monosaccharides amino acids nucleotides fatty acids
Answer:
calcium is not a main element of calcium . question 2 hemoglobin is a globular protein with an embedded heme group. so a transportation protein and question 3 the building blocks of proteins are amino acids.
Explanation:
1. The element that is not part of the four main elements of amino acids would be calcium
2. Hemoglobin is a type of transport protein.
3. The building blocks of proteins are amino acids.
Amino acids represent the building blocks of proteins. They are made up of four main elements in the form of carbon, nitrogen, oxygen, and hydrogen. Some amino acids have other elements such as sulfur in methionine and cysteine. Amino acids are joined together by peptide bonds to form proteins.
Hemoglobin is a protein molecule whose characteristic red coloration is caused by the presence of iron. The molecule is found abundantly in the blood of mammals and primarily serves as an oxygen transporter in the circulatory system. Hemoglobin reversibly bonds with oxygen in the lung to form bright red oxyhemoglobin. The oxygenated blood is then transported around the body during which the oxyhemoglobin bond is broken to release oxygen to different cells of the body.
In summary, calcium is not part of the four main elemental compositions of amino acids, amino acids are the building blocks of proteins, and hemoglobin is primarily a transport protein.

Which of the following statements about archaea are true cowan?A) They are prokaryotes.B) They lack peptidoglycan in their cell walls.C) Some are thermoacidophiles; others are extreme halophiles.D) They evolved before bacteria.E) Some produce methane from carbon dioxide and hydrogen.
Answer:
All the options are true except option D.
Explanation:
Archaea are a group of prokaryotic organisms i.e. they lack a membrane bound nucleus. They are one of the the three domains of life (the other two being bacteria and eukarya). Archeans possess a cell wall like bacteria but it is not composed of peptidoglycan, like bacteria cell wall.
Archeans are generally known to be found in very severe environmental conditions, hence, they are referred to as extremophiles e.g Some are thermoacidophiles i.e. thrive in very hot and acidic environment while others are extreme halophiles i.e. thrive in salty regions. Archeans known as methanogens produce methane gas as a product of metabolism from carbon dioxide and hydrogen.
However, the domain archeae was only found to be in existence recently after the domain bacteria, hence, they are not considered to evolve before the domain bacteria.

Explain how the streamlined body of a bony fish enable it to live successfully in water.
The streamline body of a fish enables it to easily move through water current without having to experience much difficult. In short, it doesn't have any body structure compared to that of a neck and this enabling it to move faster and easier in water.
A bony fish's streamlined body is an adaptation that allows it to survive in water. A bony fish's body is hydrodynamically shaped, which implies that it has a form that lessens the drag it feels in the water.
What is the reason for them being crucial ?This is crucial because it enables the fish to swim more effectively, which enables it to move more quickly and for longer stretches of time without using up a lot of energy. Bony fish have streamlined bodies that allow them to glide through the water more silently.
This is important as it enables the fish to sneak up on prey without being detected, and also helps it to avoid predators. Additionally, the shape of the body lessens turbulence in the water, which aids in minimising the noise the fish makes.
A bony fish's sleek shape also aids in maintaining stability and balance in the water. The fish can maintain its equilibrium and avoid being knocked off course by waves and currents because to the body's reduced drag and turbulence design. The fish can move more swiftly and effectively as a result, which also helps it evade predators.

In humans, red blood cells are the only cells that eject their nuclei as they develop. By emptying themselves of nuclei, these cells are able to do
which of the following?
replace themselves quickly when more cells are needed
transport greater amounts of oxygen and waste throughout the body
transmit electrical impulses quickly
attack bacterial pathogens more effectively
Answer:
Transport greater amounts of oxygen and waste products.
Explanation:
Not having nuclei allows the red blood cells (RBCs) to have more space for haemoglobin (Hb). Haemoglobin is the oxygen-carrying pigment in the RBCs. So more Hb means more oxygen transport.
Hb also carries carbon dioxide, a waste product.
In humans, red blood cells are the only cells that eject their nuclei as they develop, so by emptying themselves of nuclei, these cells are able to transport greater amounts of oxygen and waste throughout the body, which is the second option.
What is the function of red blood cells in humans?The human and other vertebrates have different types of blood cells, and in humans there are white blood cells and red blood cells. In red blood cells, there is no nucleus when the cell gets mature, so the red blood cells get hemoglobin at that place to carry most of the oxygen through the body and remove the carbon dioxide.
Hence, in humans, red blood cells are the only cells that eject their nuclei as they develop, so by emptying themselves of nuclei, these cells are able to transport greater amounts of oxygen and waste throughout the body, which is the second option.
