a. The % Daily Value for sodium, calcium, potassium, magnesium, and iron will be listed.
b. Saturated, unsaturated, and trans fat amounts will NOT be listed separately.
c. The serving size will NOT be specified, because USDA serving sizes are assumed.
d. The kcalories and amounts of sodium and saturated fats will be listed.
e. Carbohydrates will be broken down into simple and complex carbs.
Answer:
d. The kcalories and amounts of sodium and saturated fats will be listed.
Explanation:
Charles can be certain that the kilocalories and amounts of sodium and saturated fats will be listed. Thus, the correct option for this question is D.
What is Nutritional information?Nutritional information may be defined as the process of representing all sorts of information related to food, food materials, or dietary supplements, as well as the quantity of each nutrient that you will receive after the consumption of a specific food product.
Nutritional information always deals with the accumulation of energy in kilocalories (kcal), the composition of each essential nutrient like proteins, carbohydrates, and saturated fats, along with the demonstration of elements like sodium, potassium, etc. in the food level of each and every edible product.
Therefore, Charles can be certain that the kilocalories and amounts of sodium and saturated fats will be listed. Thus, the correct option for this question is D.

The Smith children, although genetically related, all show slight variations in the color of their hair. These variations are most likely the result of
These variations are most likely the result of polygenic effects. Polygenic traits are controlled by many genes.
Polygenes and inheritanceThe phenotype is any observable feature of an organism, which depends on genotype and environment.
The inherited genes largely determine different phenotypic features (e.g., eye color, weight, etc).
Traits controlled by a single gene are called monogenic, whereas traits controlled by two or more genes are known as polygenic.

The natural atoms needed for building cell material and tissues should come from food. Carbs or sugars are the essential wellspring of natural carbons in the creature body. During absorption, absorbable starches are at last separated into glucose and used to give energy through metabolic pathways.
Sickle-cell anemia is a disease that is caused by __________ in the __________ of the protein.
Sickle-cell anemia is a disease that is caused by a mutation in the beta-globin chain of the protein, hemoglobin.
What is sickle cell anemia?Sickle cell anemia is a disease caused by a mutation in the beta-globin chain of the protein hemoglobin.
The mutation occurs on the beta-hemoglobin gene found on chromosome 11.
In sickle cell anemia, the red blood cells have as sickle shape and are unable to transport oxygen effectively in the body.
Therefore, sickle-cell anemia is a disease that is caused by a mutation in the beta-globin chain of the protein, hemoglobin.

explain genetic drift using the bottleneck effect and founder effect
[tex]\huge{\underline{\underline{\boxed{\sf{ \orange{ αηѕωєя : }}}}}}[/tex]
Genetic drift can cause big losses of genetic variation for small populations.Population bottlenecks occur when a population’s size is reduced for at least one generation.Because genetic drift acts more quickly to reduce genetic variation in small populations, undergoing a bottleneck can reduce a population’s genetic variation by a lot, even if the bottleneck doesn’t last for very many generations. This is illustrated by the bags of marbles shown below, where, in generation 2, an unusually small draw creates a bottleneck.Hope Helps~HELPPPPPPPPPPPPPP

At which point is the population experiencing carrying capacity?
1
in
Number of fruit flies -
Time
It is reaching carrying capacity at point c because that is where their population starts to plateau on the graph which tells me that their environment cannot hold more any more of them.
The carrying capacity of the fruit fly population is depicted by C. Option c is correct as it shows the carrying capacity. The carrying capacity is the range within which the maximum individual can fit in an ecosystem.
What is carrying capacity?
Carrying capacity means the ecosystem has the capacity to carry that specific number of individuals, and after this range, the population can't survive in that ecosystem. When the population exceeds the carrying capacity, competition for space and food begins, resulting in the death of some members of the species.
The A in the graph depicts the fruit fly population at its initial level. B depicts that the fruitflies are growing rapidly as there is an ample amount of resources. By the time they reach the C, the growth has slowed. After this range, the ecosystem can't provide resources for this population to grow in number.
Hence, The carrying capacity of the fruit fly population is depicted by C.
