Answer:
0.058 % kcalories comes from carbohydrate.
Explanation:
1 g of carbohydrtes gives 4 calories, 1 g of protein gives 4 kcalories, 1 gm of fat gives 9 calories and 1 g of alcohol gives 7 calories of energy.
Thus in a meal that contains 110 g carbohydrates gives 110 x 4 = 440 calories, 25 g protein gives 25 x 4 = 100 calories, 20 g fat gives 20 x 9 = 180 calories and 5 g alcohol gives 5 x 7 = 35 calories.
Total calories in a meal 440+100+180+35 = 755.
Therefore % of carbogydrate will be 440x 100 divided by 755 = 58.27 %
In kcalories % would be 58.27/1000 = 0.5827 %
Answer:
A malaria outbreak causing allele frequencies to change is an example of <u><em>natural selection.</em></u>
Explanation:
Natural selection is a type of selection in which those organisms are favoured to live and reproduce which are better adapted to live in an environment. Due to natural selection, the allele frequencies of a population will tend to change with the passage of time.
When the outbreak of malaria occurs, those organisms which do not catch malaria are able to survive and pass on their characteristics to their offsprings. the other organisms die and do not reproduce. This will cause changes in the allele frequencies.
Answer: a. Desert
Explanation:
The tropical climatic zone has three different biomes such as tropical rainforests, the tropical savannas and tropical deserts. The tropical climatic zone is the hottest of all the climatic zones as it can be found on and near the equator, this region receives the maximum sunlight energy year around.
Therefore, on the basis of the above information, the desert is the correct option. The desert biome is the hottest and driest region of the earth. This region receives very low annual rainfall.
It is a mixture.
take salt water for example if you boil the water the salt will be left behind. salt water on its own is not a pure substance a pure substance would be just the water by its self.
hope that helps.
An error in transcription/translation affects only one cell.
An error in DNA replication would affect many generations of cells.
