A woman consumes 500 grams of carbohydrates, 30 grams of protein, and 75 grams of fat in one day. how many total kcalories has s
DedPeter [7]
To calculate the energy offered from food, multiply the number of grams of protein, carbohydrate, and fat by 4, 4, and 9, respectively.
Then add the results together.

Given: 500 grams of carbohydrates, 30 grams of protein, and 75 grams of fat in one day.

500 grams x 4 kcal/g = 2000 kcal
30 grams x 4 kcal/g = 120 kcal
75 grams x 9 kcal/g = 675 kcal
= 2795 kcal

From this data, you can calculate the percentage of k calories each of the energy nutrients give to the total.
Solution:

2000/2795 * 100% = 72% from carbohydrates
120/2795 * 100% = 4% from protein
675/2795 * 100% = 24% from fat
Total: 100%

The disease cystic fibrosis (CF) is caused by a mutation to the CFTR gene which affects the respiratory, endocrine, reproductive
Lady bird [3.3K]

Answer: DF508 mutation. A Genetic, Hereditary, Autosomal and Recessive Mutation.

Explanation:

Cystic fibrosis (CF) is a recessive autosomal lethal disease, it is most common on Caucasoid populations. Its diagnosis is suggested by the clinical features of chronic obstructive pulmonary disease, persistent pulmonary colonization (particularly with mucoid Pseudomonas strains), meconium ileus, pancreatic insufficiency with or familiarity history of the disease. The FC gene is large, with about 250 Kb of genomic DNA, 27 exons representing about 5% of genomic DNA; encodes a 6.5 kb transcribed mRNA. This mRNA is transcribed into a protein of 1480 amino acid called CFTR (Regulator Transmembrane Conductance Cystic Fibrosis). When a three-base pair deletion, adenosine-thymine-thymine (ATT) identified in the CFTR gene, exon 10, it results in the loss of a single amino acid phenylalanine at position 508 of the protein. This mutation is called DF508; “D” stands for deletion and “F” for phenylalanine amino acid.

Animals in the chaparral biome are not especially vulnerable to drought. Please select the best answer from the choices provided
Marina CMI [18]

Answer;

The above statement is true

Explanation;

Some of the adaptations of the chaparral fauna are that the animals do not require much water. The animals have learned to live in their biome by being nocturnal and are usually small. The animals are all mainly grassland and desert types adapted to hot, dry weather.

Organisms that live in the chaparral have developed unique adaptations that aid in their survival. Coyote brush is a unique plant found in the chaparral of California and Oregon. The shape a coyote brush takes depends on the location in which it is growing, but each coyote brush plant develops a large root system that extends outward many yards from the main plan
