molecules of?
Answers:

C6H12O6
Answers
Answer:
Energy is stored in glucose molecules C6H12O6
Explanation:
Producers make sugars stored as monomers bonded together to form polysaccharides, long chain hydrocarbon molecules as a result of the process of photosynthesis. These molecules, like the monosaccharide glucose, store converted solar energy as stable chemical energy in covalent bonds. In covalent bonding, the elements share electrons with each other.
These high-energy bonds are stable and not easily destabilized or broken. The energy is retrieved the the process of respiration in the mitochondria.
Glucose is broken down, while energy is transferred to bonds between ADP and inorganic phosphate, to produce ATP (adenosine triphosphate).
Eg. for aerobic respiration...
C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
glucose+ oxygen → carbon dioxide+ water+ energy

A theme in biology is how structure is related to function. Discuss how the structures of the different chambers and vessels of the heart relate to their functions. Answer should consist of 3-5 sentences, citing specific chambers of the heart to their function and why.
Answers
Answer: Different chambers of the heart perform different functions.
Explanation:
The human heart has four chambers the two atria as well as two ventricles. The function of the lower chambers of the heart is to pump out blood. The atria or upper chambers receive blood. The right atrium obtains blood from the superior vena cava then the blood moves towards the right ventricle where the deoxygenated blood is pumped out to the lungs. From the left ventricles the blood is pumped to all the parts of the body.
The heart is the major and the most important organ of the circulatory system that is responsible for transporting the oxygenated blood to the organs and deoxygenated blood from the organs.
The organ has four sections including the atrium and the ventricles. Different functions of various chambers can be explained as:
The upper right compartment is called the atrium and accepts the blood through veins and transports them to the right ventricle.The lower right compartment is called the right ventricle that receives blood from the atrium and sends it to the lungs for supplementing it with the oxygen molecules.The upper left compartment is called the left atrium and gets loaded with oxygenated blood from the lungs and transports it to the left ventricle.The lower left compartment is called the left ventricle that receives the oxygenated blood from the upper compartment and pumps it to all the body organs.Therefore, different chambers of the heart perform various functions.

During the months of July, August, and September, when the squirrels are more active we would expect the artic squirrels:
A) To produce more O2 when compared to other months.
B) To have a higher output of CO2.
C) To produce less water.
D) Increase in the output of glucose.
Answers
Answer:
B) To have a higher output of CO2.
Explanation:
We would expect the artic squirrels to produce a higher output of CO₂. As with most heterotrophs, the by-product of their respiratory activities is the formation of carbon dioxide gas.
They use oxygen gas to break down glucose. The process releases energy for their life activities. The waste product is usually carbon dioxide which enters back into the ecosystem as a waste.Analogy for chloroplast

The cells that make up the monkeys in Osmosis Jones are known as White blood cells.
What is Osmosis?Osmosis may be defined as the process that significantly involves the movement of water from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a semi-permeable membrane.
White blood cells play numerous important functions in the body of each and every living organism. They perform the function of protecting the body against infections. These cells have an important role in inflammation along with allergic responses.
There are two types of white blood cells that are considerably formed in the bone marrow. They are phagocytes and lymphocytes.

List the four types stem cells, give an example of each type, and explain how much each type can differentiate.
Answers
Embryonic stem cells
Embryonic stem cells are obtained from the inner cell mass of the blastocyst, a mainly hollow ball of cells that, in the human, forms three to five days after an egg cell is fertilized by a sperm. A human blastocyst is about the size of the dot above this “i.”
In normal development, the cells inside the inner cell mass will give rise to the more specialized cells that give rise to the entire body—all of our tissues and organs. However, when scientists extract the inner cell mass and grow these cells in special laboratory conditions, they retain the properties of embryonic stem cells.
Embryonic stem cells are pluripotent, meaning they can give rise to every cell type in the fully formed body, but not the placenta and umbilical cord. These cells are incredibly valuable because they provide a renewable resource for studying normal development and disease, and for testing drugs and other therapies. Human embryonic stem cells have been derived primarily from blastocysts created by in vitro fertilization (IVF) for assisted reproduction that were no longer needed.
Tissue-specific stem cells
Tissue-specific stem cells (also referred to as somatic or adult stem cells) are more specialized than embryonic stem cells. Typically, these stem cells can generate different cell types for the specific tissue or organ in which they live.
For example, blood-forming (or hematopoietic) stem cells in the bone marrow can give rise to red blood cells, white blood cells and platelets. However, blood-forming stem cells don’t generate liver or lung or brain cells, and stem cells in other tissues and organs don’t generate red or white blood cells or platelets.
Some tissues and organs within your body contain small caches of tissue-specific stem cells whose job it is to replace cells from that tissue that are lost in normal day-to-day living or in injury, such as those in your skin, blood, and the lining of your gut.
Tissue-specific stem cells can be difficult to find in the human body, and they don’t seem to self-renew in culture as easily as embryonic stem cells do. However, study of these cells has increased our general knowledge about normal development, what changes in aging, and what happens with injury and disease.
MESENCHYMAL STEM CELLS:
You may hear the term “mesenchymal stem cell” or MSC to refer to cells isolated from stroma, the connective tissue that surrounds other tissues and organs. Cells by this name are more accurately called “stromal cells” by many scientists. The first MSCs were discovered in the bone marrow and were shown to be capable of making bone, cartilage and fat cells. Since then, they have been grown from other tissues, such as fat and cord blood. Various MSCs are thought to have stem cell, and even immunomodulatory, properties and are being tested as treatments for a great many disorders, but there is little evidence to date that they are beneficial. Scientists do not fully understand whether these cells are actually stem cells or what types of cells they are capable of generating. They do agree that not all MSCs are the same, and that their characteristics depend on where in the body they come from and how they are isolated and grown.
Induced pluripotent stem cells
Induced pluripotent stem (iPS) cells are cells that have been engineered in the lab by converting tissue-specific cells, such as skin cells, into cells that behave like embryonic stem cells. IPS cells are critical tools to help scientists learn more about normal development and disease onset and progression, and they are also useful for developing and testing new drugs and therapies.
While iPS cells share many of the same characteristics of embryonic stem cells, including the ability to give rise to all the cell types in the body, they aren’t exactly the same. Scientists are exploring what these differences are and what they mean. For one thing, the first iPS cells were produced by using viruses to insert extra copies of genes into tissue-specific cells. Researchers are experimenting with many alternative ways to create iPS cells so that they can ultimately be used as a source of cells or tissues for medical treatments.

3. Climate change has been a topic repeatedly mentioned in our study of Marine Science.
How does Jackson express the impact that climate change has on corals? Based on how
he uses it, what do you infer the word symbiosis to mean?
Answers
Answer:
Climate change lead to the destruction of corals due a warming of the oceans, increase in ocean acidity as gases such as carbon dioxide are absorbed into the oceans, rise in sea level due to melting glaciers and increase in precipitation, changes in storm patterns, etc.
Symbiosis is a close relationship between two dissimilar organisms which usually results in benefits to one or both organisms.
Note: The study material was not provided.
Explanation:
Greenhouse gas emissions from human activities have led to an increase in global surface temperature. This has resulted in a warming of the oceans, increase in ocean acidity as gases such as carbon dioxide are absorbed into the oceans, rise in sea level due to melting glaciers and increase in precipitation, changes in storm patterns, etc.
The warming of the oceans poses a great threat to life and activities in the ocean. Coral reefs especially are affected by a warming of the ocean in the following ways:
mass coral bleaching- with increase in ocean temperature, corals remove the algae living in association with them that are responsible for their colour, thereby turning corals white. With prolonged bleaching periods, the corals eventually eventually die .Sea level rise: with rise in sea level comes a likelihood of increase in flow of sediments into the sea. This sediments when deposited on corals found near land suffocates and kill the corals.Changes in storm patterns: stronger and more frequent storms can lead to a destruction of coral reefs. Increase in the acidity of oceans results in death of corals.Corals and algae exist in a symbiotic (mutualistic) relationship in coral reefs. The coral provides the algae with a protected environment and compounds they need for photosynthesis. In return, the algae produce oxygen and help the coral to remove wastes.
Therefore, symbiosis is a close relationship between two dissimilar organisms which usually results in benefits to one or both organisms.
