The role that is played by macromolecules such as starch and simple sugars in fruit storage and ripening is that the unripe bananas store starch in their chlorophyll.
Macromolecules refer to very large molecules. The four main classes of macromolecules include lipids, proteins, nucleic acid, and carbohydrates.
It should be noted that starch is stored in the chlorophyll content of the peel of the unripe bananas. During ripening, there'll be an increase in the breakdown of the starch that can be found in the fruit and this will ensure there's an increase in the glucose too.

Which layer of the
earth has the greatest
density? Why?
Answer: metal inner core
Explanation:
It is made of the densest components & it is under the greatest compression; due to the overlying layers.
The inner core of Earth has the greatest density due to:
- The inner core is made of solid iron and nickel
- The inner core gets consolidated due to pressure exerted by the other top layers.
What are the different layers of the Earth?
Generally the Earth is made of three different layers:
- Crust- The outer layer
- Mantle - The Middle Layer
- Core - The Inner Layer.
Crust:
Outer layer of the Earth and is thin, brittle and cold compared to other layers.
It is majorly made of light elements especially silica, aluminum and oxygen.
The thickness of crust varies for for land and ocean where the former is thicker than latter.
Mantle:
It is around 3000 km thick and is the thickest layer of the Earth. It starts mere at 30 km from the earth's crust.
It is majorly made of Iron, Magnesium and silicon and is dense, hot and semi solid.
The upper part of the mantle is liquid in nature called as Asthenosphere and it is believed that tectonic plates rides upon here and slide across.
Core:
Core is further divided into Outer core and Inner core.
Outer core is made of iron and nickel and is liquid in nature. It is heated largely by the radioactive decay of the elements of the uranium and thorium and this liquid churn huge turbulent current.
Inner core is a solid metal ball having radius of 1220 km. It is extremely dense and is mostly made of iron and nickel.
The temperature of inner core is similar to that of the surface of sun along with high amount of pressure.
Thus this layer has the greatest density amongst all the layers of the Earth.

can anyone writet about describing ● History of Ribosomes.
Answer:
The ribosome is a complex molecule made of ribosomal RNA molecules and proteins that form a factory for protein synthesis in cells. In 1955, George E. Palade discovered ribosomes and described them as small particles in the cytoplasm that preferentially associated with the endoplasmic reticulum membrane. Along with other scientists, Palade discovered that ribosomes performed protein synthesis in cells, and he was awarded the Nobel Prize in 1974 for his work.
Each ribosome has a large component and a small component that together form a single unit composed of several ribosomal RNA molecules and dozens of proteins. The ribosome is responsible for translating encoded messages from messenger RNA molecules to synthesize proteins from amino acids. The ribosome translates each codon, or set of three nucleotides, of the mRNA template and matches it with the appropriate amino acid in a process called translation. The amino acid is provided by a transfer RNA (tRNA) molecule. Each newly translated amino acid is then added to the growing protein chain until the ribosome completes the process of protein synthesis.

Answer:
Covalent bond
Explanation:
The answer is covalent bond
A molecule of octane which is a component of gasoline contains covalent bonds.
Octane is a hydrocarbon compound, specifically an alkane, with the molecular formula C8H18. The structure you've provided illustrates the arrangement of carbon (C) and hydrogen (H) atoms in octane.
In octane, each carbon atom forms four single covalent bonds with other atoms (either carbon or hydrogen). Covalent bonds are formed when atoms share electrons to achieve a stable electron configuration. In the case of octane, carbon atoms share electrons with other carbon and hydrogen atoms to fill their valence electron shells, resulting in a stable and energetically favorable arrangement.
The structure of octane is a straight-chain alkane, with carbon atoms forming a chain and hydrogen atoms attached to the carbon atoms. The single covalent bonds between the atoms are represented by lines in the structural formula.
The shape of the molecule is determined by the arrangement of atoms and the types of bonds between them. In the case of octane, the single covalent bonds allow the carbon atoms to form a linear chain.
In conclusion, octane molecules are held together by covalent bonds, specifically single covalent bonds between carbon and hydrogen atoms. This type of bonding contributes to the stability and structure of the octane molecule, making it a major component of gasoline and contributing to its combustible properties.

Plants release oxygen as a by-product of photosynthesis. Draw a conclusion about other life forms in the lake, based on this data. A) All of the life forms in the lake can be found within the top 10 feet of water. B) As you increase in depth of water, plant density decreases while fish density increases. C) Organisms in the lake rely on dissolved oxygen to survive. The lower the dissolved oxygen, the lower the survival rate. D) Plant survival is related to the amount of light (depth) but animal survival is related to the amount of oxygen available. The lower the amount of dissolved oxygen, the less animal life present in the lake.
Algae growth produces a high concentration of oxygen on the surface, which decreases with depth. The less oxygen available in deeper strata, the fewer surviving forms of life. The correct option is C.
-----------------------------------------------------------------------------------------------------------
Available data:
Depth of Water Dissolved Oxygen Amount of Algae/sq. meter
(meters) (mg O₂ per liter) (kilogram)
1 9.2 550
5 9.0 535
10 8.5 404
15 7.0 155
20 5.5 45
25 4.2 12
According to this table,
On the surface, there is a higher amount of algae, and hence, more dissolved oxygen. As it gets deeper, algae amount decreases as well as dissolved oxygen.
If oxygen decreases with depth, it suggests that plants -oxygen producers- lack, probably due to the lack of sunlight reaching the bottom.
Other forms of life
Algae growth on the surface blocks the pass of light to the deeper strata.The lack of light in deeper strata affects plants' growth.If there are no plants in deeper areas, there is no dissolved oxygen.Since animals need oxygen, they probably can not survive in deep regions.With no oxygen, the bottom turns into an anaerobic environment, in which anaerobic bacteria can survive.
These conditions can be related to eutrophication.
Eutrophication is a biological process produced in water by an oversupply of nutrients or organic matter.
This oversupply, mainly of nitrogen or phosphorous, favors phytoplankton multiplication, especially cyanobacteria.
Cyanobacteria overgrowth leads to an enhance in primary productivity and reduces the pass of radiation to deeper strata. This fact affects biota in deeper zones.
Gradually sedimentation begins, caused by the death of some vegetable organisms that sink in the bottom.
These sediments suffer decomposition in the absence of oxygen. Anaerobic bacteria act and produce fermentation.
Phytoplankton overgrowth on the surface and fermentation process in the bottom, originate toxic compounds that can damage the animals in the water body.
Animals die, creating more sediments in the bottom where there are anaerobic conditions.
The continued increase in decomposition and fermentation produces a bad smell and toxicity.
The result of eutrophication is the stratification of the water mass:
First superficial layer, the overgrowth of blue-green algae, produces toxins and interrupts the pass of light to deeper areas. The surface then becomes warmer. The second layer might have oxygen available for the animals. In the third layer, there is no oxygen, so life is impossible for animals or plants. In the fourth layer, there are animals and plant remains in the process of sedimentation. At the bottom, there are organic matter and anaerobic bacteria in charge of decomposition and fermentation, through which they produce toxic gases and smell.Options:
A) All of the life forms in the lake can be found within the top 10 feet of water. FALSE. Depends on the conditions and the species.
B) As you increase in depth of water, plant density decreases while fish density increases. FALSE. Plant and animals density decrease, as available oxygen decrease.
C) Organisms in the lake rely on dissolved oxygen to survive. The lower the dissolved oxygen, the lower the survival rate. TRUE.
D) Plant survival is related to the amount of light (depth) but animal survival is related to the amount of oxygen available. The lower the amount of dissolved oxygen, the less animal life is present in the lake. FALSE. Light does not reach the bottom, so there are no plants there. Plants also depend on oxygen, not only animals.

in the adult digestive tract, where do lipases break fat into fragments so that it can be absorbed into the lymph?
As to the digestive tract, the function of the lipases would take place in the small intestine.
Lipase is an enzyme that helps us to metabolize fat. It does this through hydrolysis. Although in reality, as an enzyme, its main function is to catalyze this process. Lipases are the subclass enzyme of the esterases.
Lipases are necessary for the proper digestion and transport of fats in the form of lipids. They are also essential to process these lipids in the human body. This enzyme is present in most living organisms outside of humans.
Although lipase enzymes are produced throughout the body, the bulk of lipase production occurs in the pancreas. It will then travel to the small intestine to carry out its functions in the digestive tract.

https://brainly.com/question/2847647?referrer=searchResults
In the adult digestive tract, lipases in the small intestine break fat into fragments so that it can be absorbed into the lymph.
Fat digestion occurs efficiently and almost completely in the small intestine by pancreatic secretion of lipases.
Pancreatic lipase acts on triacylglycerides to give free fatty acids and monoacylglycerides.
First, they are absorbed by the epithelial cells of the intestinal wall called enterocytes, creating complex particles called chylomicrons, loaded with triglycerides.
Fatty acids are re-esterified within the enterocyte and enter circulation through the lymphatic pathway as chylomicrons.
Chylomicrons bind to lymph, which carries them to the bloodstream, this indicates the great importance of lymph in the process of assimilation of dietary fats.
Therefore, we can conclude that in the adult digestive tract, lipases in the small intestine break fat into fragments so that it can be absorbed into the lymph.

10. Explain how both a population of moose and wolves in the same area could each affect the
size and distribution of the plant population in a community:
Answer:
Since moose are herbivores, they could cause a plant population to decrease in size.
Since wolves are carnivores and hunt moose, there would be less moose feasting on plants, so the plant population would be allowed time to grow back larger.
Depending on how many wolves there are to moose, the plant population will tend to vary.
For example: If the moose population is greater than the wolf population, there will be a smaller population of plants. On the other hand, if the wolf population is greater than the moose population, there will be a greater population of plants.
