how proteins are made
Proteins are an important class of molecules that carry out most of the work inside cells. The building blocks of proteins are smaller organic molecules called amino acids. Most organisms, including humans, use only 20 different amino acids to assemble the vast multitude of proteins needed to build and run a cell.
To build proteins, cells use a complex assembly of molecules called a ribosome. The ribosome assembles amino acids into the proper order and links them together via peptide bonds. This process, known as translation, creates a long string of amino acids called a polypeptide chain.
After the polypeptide chain is synthesized, it will sometimes undergo additional processing. For example, some proteins will have certain amino acids removed. Or extra molecules such as sugars or phosphates may be attached to some of the amino acids in a protein.
Answer:
proteins are made of large numbers of amino acids joined end to end. The chains fold up to form 3d molecules with complex shapes - you could think of it as origami with very long and thin piece of paper

Explain E.O. Wilson's theory of Island Biogeography as it applies to environments other than islands physically
surrounded by water.
Answer:
The theory of E.O. Wilson's theory of Island Biogeography was originally developed as island biogeography, to explain species richness of actual islands, surrounded by water.
It proposes that the number of species found in an undisturbed environment is determined by immigration and emigration. According to him, the species richness will be the same if this island will have an equal number of the immigration and extinction or emigration of species.

How does variation affect an organism?
Answer:
Explanation:
Genetic variation in a group of organisms enables some organisms to survive better than others in the environment in which they live. Organisms of even a small population can differ strikingly in terms of how well suited they are for life in a certain environment. An example would be moths of the same species with different color wings.

Distinguish between an acid and alkaline slant?
Answer:
Acid slant: yellow, fermentation of glucose and lactose and/or sucrose. High concentration creates excessive acid formation
Alkaline slant: red, limited glucose in the medium and limited acid formation.
The pH of acids is less than 7. Alkalis have a pH more than 7 The pH of neutral substances is 7. If metal oxides are soluble in water, they are alkaline. Non-metal oxides are acidic, if soluble in water.
What are acids?An acid is a molecule or ion that can either donate a proton (Bronsted-Lowry acid) or form a covalent bond with an electron pair (Lewis acid). The proton donors, also known as Bronsted-Lowry acids, are the first type of acid.
Only dextrose fermentation produces an alkaline/acid (red slant/yellow butt) reaction.
The fermentation of dextrose, lactose, and/or sucrose is indicated by an acid/acid (yellow slant/yellow butt) reaction.
An alkaline/alkaline reaction occurs when as a result, carbohydrate fermentation does not occur.
The presence of red (alkaline) in the slant and butt indicates that the organism being tested is a nonfermenter.
The formation of hydrogen sulfide results in a black precipitate in the butt of the tube. The splitting and cracking of the medium indicates gas production.
Thus, these are the basic difference between acid and alkaline slant.

Explanation:
Select an organism of your interest! Research to see if that organism undergoes asexual or sexual reproduction. Describe why that type of reproduction is advantageous for your organism.
Answer:
Many fungi and plants reproduce asexually. Some plants have specialized structures for reproduction via fragmentation.
Explanation:
This allows them to adjust to conditions in the environment. They can spread quickly through asexual reproduction when conditions are stable. They can increase their genetic variation through sexual reproduction when conditions are changing and variation may help them survive.
Reproduction is a method by which the genetic material from the parent is transferred to offspring and in this way the character and traits are passed from generations.
I will select plants for my research purpose.
Plants are species that reproduce sexually. They have male and female organs that produce cells for reproductions. They sexually reproduce through the process of pollination.
This method of reproduction helps in genetic variation and in forming recombinant species that are more variant.
This variation helps the plant species to survive better compared to less competent species.
Sexual reproduction is beneficial for plants as it increases varieties and helps plants in fighting against a common population disease.

Answer:
I think it's B and D.
Explanation:
1) Identify 4 stimuli that cause a decrease in the number of producers, consumers, and decomposers living in an area.
2) What could be the effects in relation to the energy pyramid, population, and community of organisms within the environment.
Answer:
Temperature, humidity, food and water.
Explanation:
Temperature, humidity, food and water are the four stimuli that is responsible for the decrease in the population of producers, consumers, and decomposers living in that area. If the temperature is too high or too cold, the growth of the producer stops and the plants can't tolerate the temperature will die. The death of producers causes the death of consumers because consumers depend on these producers for food. The population of decomposer also decreases if the environment is too harsh because decomposers also requires suitable environment for growth and survival. There is adverse effect on the energy pyramid, population, and community of organisms within the environment if these stimuli are not present in suitable range.

Both King penguin and Emperor penguin have similar appearance and look very similar to each other with some differences in their shape which make them different species.
Explain how deforestation can lead
to changes in the sea level.
*In 5 sentences or more*
Answer:
Explanation: Deforestation leads to climate change. The fewer trees in environment, the more carbon emmsision there is which warms up the earth. As the earth gets warmer the glaciers and ice caps in the artic and antarctic melt which leads to more water in the ocean. Think of ice melting in a glass of water, the ice melts and turns to water creating more water.
You are studying aging in budding yeast. With each division, mother yeast cells bud and divide, forming a daughter that has renewed replicative potential (in other words, it is rejuvenated). The mother, however, does not show a renewed replicative potential. You find that the mother cell dies after a few more divisions, but the daughter cell dies after it divides 30 or more times.

1. Normal red blood cells can barely squeeze through the capillaries (the tiniest blood vessels). What
problems might be caused by sickle-shaped red blood cells?
Sickle-shaped red blood cells would slow down or cause a blockage (blood clot) to the blood vessels further leading to attacks such as heart attacks.
This is due to the fact; the new shape would simply be unable to pass safely through the small blood vessels to perform its main purpose of transferring oxygen throughout the body.

Which of the following is not a property of fibre?
O a. It delays gastric emptying
Ob.it
It provides a feeling of satiety
O c It elevates blood glucose levels
O d. It contributes 6-10 kilojoules per gram.
Answer: The correct option is C ( It elevates blood glucose levels).
Explanation:
All animals feed on ready - made food. This food is made up of several groups of substances.All food taken in by an animal can be divided into six groups of food substances or nutrients. They are carbohydrates, proteins, fats and oil, mineral salts, vitamins and water.
Fibres is defined as foods that are usually of plant origin which are indigestible and stimulates movement of the bowels by providing bulk to the intestinal content.
Examples of the plant based food which are rich in fibre include:
--> grains,
--> fruits,
--> vegetables,
--> nuts, and beans.
Fibre is further divided into two:
--> Insoluble fibre: This is also called roughages. They include fruits and vegetables with their backs, whole grains.
--> Soluble fibre: This is the jelly-like fibre that dissolves in water. It includes the flesh of fruits and vegetables, oats.
All fibers can slow the absorption of sugar and fat from food, and therefore help prevent spikes in blood sugar. Therefore the option that fibre elevates blood glucose levels is NOT a property of fibre.
Answer:
c It elevates blood glucose levels
Explanation:
Elevation of blood glucose levels is not the property of fiber because fiber helps control blood sugar. Fiber can't be converted into glucose or fiber does not have glucose so the concentration of glucose can not be increased if more fiber is eaten. Fiber provides a feeling of satiety as well responsible for gastric emptying. One gram of fiber produces 8 kilojoules per gram. So we can conclude that blood glucose level can't be increases due to fiber.
