Answer:
The correct answer will be option- Fats
Explanation:
The cellular respiration can produce energy from the three substrates: Carbohydrates, proteins and Fat, the most favoured of which is Carbohydrates.
The Carbohydrates on oxidation produces 4 calories per gram, proteins also produce 4 calories per gram whereas Fats produces 9 calories per gram.
The Fats produces the highest amount of energy as fats require more oxidation to release water and carbon dioxide as compared to Carbohydrates.
Since fats provide the highest amount of energy, therefore, option- fat is the correct answer.
Answer:
Natural selection by directional selection, was the driving force of evolution at work. The purple flowers parents were able to withstand the selective pressure and therefore emerged from completions with other flowers from previous generation, thus their dominance follow directional selection. This was the trait inherited by their offspring, the dominant purple
The gene pool of purple flower will be large; because of dominance in expression with each successive generation in both homozygote and heterozygote state, and therefore higher frequency of expression compared to the white flowers.
The frequency of allele depends on the rate expression of the allele in the population. Thus, the dominant purple flowers have high frequency of expression compared to the recessive white flowers which can only express itself in homozygote recessive state
Usually during exercise, unlike during rest times the muscle cells need to respire more. So they need more oxygen and glucose for energy and the carbon-dioxide produced as waste must be removed quickly. So when person gets tired or breathes heavily during intensive workouts means they are in need of more oxygen. So the cells starts performing anaerobic(lactic acid ) respiration even though it releases less energy.
Antibiotics are medicines that help stop infections caused by bacteria. They do this by killing the bacteria or by keeping them from copying themselves or reproducing.
Antibiotics are used to treat or prevent some types of bacterial infections. They are not effective against viral infections, such as the common cold or flu. Antibiotics should only be prescribed to treat health problems: that are not serious but are unlikely to clear up without antibiotics – such as acne.
A general term for narrowing would be contracting. I assume that this is applicable to the rectum, as it is a muscular tissue, and muscles are able to expand (extend, rather), and contract.
Hope this helps. And I hope I'm the brainliest!
