Answer and Explanation:
Glucose is a hexose with six carbon atoms. It is also an aldose, meaning that it has an aldehyde group, CHO in its first carbon atom. The molecule also has hydroxyl groups, OH linked to the carbon atoms.
Its linear structure shows six carbons united in a line. One of its carbon atoms is linked to a carbonate group, H-C=O. The other five carbons are linked to the hydroxyl groups, OH.
In an aqueous solution, the glucose molecule turns to the ringed or cyclic structure, as a result of the reaction among the first carbon and the oxygen of the hydroxyl group linked to the fifth carbon.
You will find the complete glucose molecule in one of the attached files (named glucose), plus the linear and cyclic structure in the other file (named glucose1).

Answer:
Glucagon is secreted
Explanation:
Glucagon is an hormone secreted by the alpha cells of the pancreatic islets. It is secreted when the blood glucose is low, when the blood glucose is high, glucagon is not secreted.
Glucagon affects the liver and some other cells but has more effect on the liver.
It allows for the release of glucose stored up in the liver cells into the blood stream to increase blood glucose.

How are metamorphic rocks formed
Hey friend your ans is here
I hope it will helpful for you
Mark as brainest answer✅
Thank you
Answer:
Metamorphic rocks are formed from other rocks that are changed because of heat or pressure.. Earth movements can cause rocks to be deeply buried or squeezed. As a result, the rocks are heated and put under great pressure . They do not melt, but the minerals they contain are changed chemically, forming metamorphic rocks.

how do cell theory, cells, and organelles link and connect?
PLEASE HELP BY 9/20-9/21/20
Answer: They are all connected .
All living organisms on Earth are divided into cells. The main concept of cell theory is that cells are the basic structural unit for all organisms. Living things may be single-celled or they may be very complex such as a human being. There are smaller pieces that make up cells such as macromolecules and organelles. A mitochondrion is an example of an organelle. If you were only made of one cell, you would be very limited. You don't find single cells that are as large as a cow.
Explanation ; easier so you can understand :)
We are made up of cells . The cell theory is that cells are what we are made of and the other animals and things in the world. Everything is made out of cells. The things that make up cells are orgenelles. That is how they are all linked up. Human > cells > oragenelles.
hope that helped :)
Answer:
Cells have many structures inside of them called organelles. These organelles are like the organs in a human and they help the cell stay alive. Each organelle has it's own specific function to help the cell survive. The nucleus of a eukaryotic cell directs the cell's activities and stores DNA.

2. Describe the property of water that is indicated
by the data. How is this property explained by the
structure of water molecules and the bonds
between them?
Answer:
The correct answer is - high specific heat.
Explanation:
Water atoms are polar, so they structure hydrogen bonds. This gives water remarkable properties, for example, a moderately high specific heat, density, adhesion, and cohesion.
A water particle comprises of two hydrogen iotas clung to an oxygen molecule, and its general structure is bowed. Oxygen even bonding with hydrogen have two sets of unshared electrons. The entirety of the electron pair and unpaired repulse one another.
Water's high specific heat is a property brought about by hydrogen holding among water particles. At the point when warmth is assimilated, hydrogen bonds are broken and water atoms can move uninhibitedly. At the point when the temperature of water diminishes, the hydrogen bonds are shaped and discharge a lot of vitality.
Thus, the correct answer is - high specific heat.
The property of water described by the heating curve is high specific heat capacity.
The specific heat capacity of a substance refers to the quantity of heat required to raise the temperature of 1 Kg of the substance by 1°C. The higher the heat capacity of a body, the greater the quantity of heat required to raise the temperature of 1 Kg of the substance by 1°C.
Looking at the heating curve, we can see that water has a very high heat capacity because a large quantity of heat is required to raise its temperature by 1°C. This is because of strong intermolecular hydrogen bonding between the molecules of water which leads to molecular association and high boiling point.

What is the function of proteins in muscles?
Answer: Muscle is a soft tissue found in most animals. Muscle cells contain protein filaments of actin and myosin that slide past one another, producing a contraction that changes both the length and the shape of the cell
Explanation:
Charles Darwin observed a unique beak size and shape in the finch population of each of the Galapagos Islands that he visited. 4 drawings of finch beaks. From left to right the beaks decrease in size. Which is the most likely cause of the observed variation? differences in the climate among the islands competition among individuals for available food sources competition among individuals for desirable mates differences in egg size among the populations
Natural selection would probably favor different varieties in the different islands. In other words, beaks changed as the birds developed different tastes for fruits, seeds, or insects picked from the ground or cacti (due to lack of food resources). Long, pointed beaks made some of them more fit for picking seeds out of cactus fruits.

Which viral life cycle can be triggered to enter into the other one? What triggers that process?
Answer:
All viruses depend on cells for reproduction and metabolic processes. By themselves, viruses do not encode for all of the enzymes necessary for viral replication. But within a host cell, a virus can commandeer cellular machinery to produce more viral particles. Bacteriophages replicate only in the cytoplasm, since prokaryotic cells do not have a nucleus or organelles. In eukaryotic cells, most DNA viruses can replicate inside the nucleus, with an exception observed in the large DNA viruses, such as the poxviruses, that can replicate in the cytoplasm. RNA viruses that infect animal cells often replicate in the cytoplasm.
The Life Cycle of Viruses with Prokaryote Hosts
The life cycle of bacteriophages has been a good model for understanding how viruses affect the cells they infect, since similar processes have been observed for eukaryotic viruses, which can cause immediate death of the cell or establish a latent or chronic infection. Virulent phages typically lead to the death of the cell through cell lysis. Temperate phages, on the other hand, can become part of a host chromosome and are replicated with the cell genome until such time as they are induced to make newly assembled viruses, or progeny viruses.
The Lytic Cycle
During the lytic cycle of virulent phage, the bacteriophage takes over the cell, reproduces new phages, and destroys the cell. T-even phage is a good example of a well-characterized class of virulent phages. There are five stages in the bacteriophage lytic cycle (see Figure 1). Attachment is the first stage in the infection process in which the phage interacts with specific bacterial surface receptors (e.g., lipopolysaccharides and OmpC protein on host surfaces). Most phages have a narrow host range and may infect one species of bacteria or one strain within a species. This unique recognition can be exploited for targeted treatment of bacterial infection by phage therapy or for phage typing to identify unique bacterial subspecies or strains. The second stage of infection is entry or penetration. This occurs through contraction of the tail sheath, which acts like a hypodermic needle to inject the viral genome through the cell wall and membrane. The phage head and remaining components remain outside the bacteria.
This figure outlines the stages of the lytic cycle. Step 1 is attachment when the phage attaches to the surface of the host. The bacteriophage is shown sitting on the surface of the bacterial host cell. Step 2 is penetration when the viral DNA enters the host cell. The image shows DNA from within the virus being injected into the host DNA. Step 3 is biosynthesis when the phage DNA replicates and the phage proteins are made. The image shows various pieces of virus being built within the cell. Step 4 is maturation when the new phage particles are assembled. This shows the viral components being put together in the cell. The fifth step is lysis when the cell lyses and the newly made phages are released. This shows the cell bursting and built viruses being released.
Figure 1. A virulent phage shows only the lytic cycle pictured here. In the lytic cycle, the phage replicates and lyses the host cell.
The third stage of infection is biosynthesis of new viral components. After entering the host cell, the virus synthesizes virus-encoded endonucleases to degrade the bacterial chromosome. It then hijacks the host cell to replicate, transcribe, and translate the necessary viral components (capsomeres, sheath, base plates, tail fibers, and viral enzymes) for the assembly of new viruses. Polymerase genes are usually expressed early in the cycle, while capsid and tail proteins are expressed later. During the maturation phase, new virions are created. To liberate free phages, the bacterial cell wall is disrupted by phage proteins such as holin or lysozyme. The final stage is release. Mature viruses burst out of the host cell in a process called lysis and the progeny viruses are liberated into the environment to infect new cells.
