Common chaperones can be identified as Hsp heat shock protein. These chaperones are identified in this way because they were discovered with heat.

The chaperone proteins are specific proteins required to fold other functional proteins within the cells.

The application of heat is able to increase the number (concentration) of chaperone proteins in specific cells.

The application of heat increases chaperone levels because it increases the denaturalization (unfolding) of proteins.

Explanation:

The Food Pyramid is a visual representation of how different foods and drinks contribute towards a healthy balanced diet. The Food Pyramid allows individuals the flexibility to choose foods and drinks from each shelf depending on their food preferences. It organises foods and drinks into 5 main shelves, starting from the most important shelf on the bottom.

Shelf 1: Vegetables, Salad and Fruit (at least 5 to 7 servings a day). Base your meals on these and enjoy a variety of colours. More is better. Limit fruit juice to unsweetened, once a day.

Shelf 2: Wholemeal Cereals and Breads, Potatoes, Pasta and Rice (3–5 servings a day, up to 7 for teenage boys and men age 19–50). Wholemeal and wholegrain cereals are best. Enjoy at each meal.

Shelf 3: Milk, Yogurt and Cheese (3 servings a day and 5 from the age of 9 to 18) Choose reduced-fat or low-fat varieties. Choose low fat milk and yogurt more often than cheese. Enjoy cheese in small amounts.

Shelf 4: Meat, Poultry, Fish, Eggs, Beans and Nuts (2 servings a day) Choose lean meat, poultry (without skin) and fish. Eat oily fish up to twice a week. Choose eggs, beans and nuts. Limit processed salty meats such as sausages, bacon and ham.

Shelf 5: Fats, Spreads and Oils (In very small amounts) Use as little as possible. Choose mono or polyunsaturated reduced fat or light spreads. Choose rapeseed, olive, canola, sunflower or corn oils. Limit mayonnaise, coleslaw and salad dressings as they also contain oil. Always cook with as little fat or oil as possible – grilling, oven-baking, steaming, boiling or stir-frying.

Top Shelf: The revised Food Pyramid separates the Top Shelf from the rest of the pyramid. The Top Shelf includes foods and drinks high in fat, sugar and salt. These are not needed for good health and should not be consumed every day. Very small amounts once or twice a week maximum is sufficient.

Healthy Eating Pyramid

Healthy Eating Pyramid

Generations of Americans are accustomed to the food pyramid design, and it’s not going away. In fact, the Healthy Eating Pyramid and the Healthy Eating Plate (as well as the Kid’s Healthy Eating Plate) complement each other.

Consumers can think of the Healthy Eating Pyramid as a grocery list:

Vegetables, fruits, whole grains, healthy oils, and healthy proteins like nuts, beans, fish, and chicken should make it into the shopping cart every week, along with a little yogurt or other dairy foods if desired.

We can confirm that one variation in the worms is the adaptation to become nocturnal eaters instead of the more dangerous diurnal eaters.

Nocturnal worms are favored over diurnal eating worms given that the main predator of worms, birds, hunt during the day. This puts the diurnal worms are a much higher risk of being consumed. Through natural selection, this will likely result in most worms being entirely nocturnal within the next 50 or so years, which can in turn lead to the evolution of more nocturnal hunting bird species.

Therefore, we can confirm that one variation in the worms is the adaptation to become nocturnal eaters instead of the more dangerous diurnal eaters, which will likely be the most common variation over time, due to natural selection.

The cost of the electricity if 42000 kWh of electricity is used is ;  $1680

Given that ;

value of electricity used = 42000 kWh

cost rate of electricity = $0.04/kWh

Final step : Determine the total cost of electricty used

unit cost = $0.04/kWh

Totals cost = unit cost * value of electricity used

                  = 0.04 * 42000 = $1680

To model translation in a cell, the student needs a clothespin, paperclip chain and the single string to represent the ribosome unit, amino acid sequence and mRNA template.

Translation is the process by which protein molecules are synthesized at the ribosomes from amino acids using mRNA as template read in the form of triplet nucleotide sequences known as codons.

If a student wishes to model the process of translation, he needs a model of the ribosome, the tRNA, amino acids and the mRNA template.

The single string serves as mRNA, the paperclip chain as newly synthesized amino acid sequence and as ribosome unit.

Therefore, the student needs a clothespin, paperclip chain and the single string to model translation in a cell.

We can confirm that one important adaptation that separated us from other animals in our evolutionary trajectory can be considered to be Bipedalism.

Bipedalism was the adaptation of early human ancestors to abandon movement on all fours and begin to walk up-right. This was a vastly important adaptation as it provided the early humans with freed hands, allowing for many other uses such as tools and social cues.

Therefore, we can confirm that one important adaptation that separated us from other animals in our evolutionary trajectory can be considered to be Bipedalism.

The evolution of similar forms in different lineages when exposed to the same selective pressures is convergent evolution.

Convergent or divergent evolution are related to the involved groups, the environments, the selective pressures, and the way in which organisms deal with them to achieve a better adaptation increasing their fitness.

Convergent evolution is the emergence of phenotypical similarities in different groups independently from each other.

Convergent evolution occurs when two or more taxonomic groups share the same traits or characteristics even when they do not share a common ancestor.

Usually, this is a pattern observed in groups that are exposed to the same or similar environmental pressures. The development of these similar phenotypes is related to higher fitness and competitive ability.
