We should remember that we should consume all necessary nutrients at a correct amount and proportion. this includes the primary food substance carbohydrates, fat and protein. and protective food substance in a small amount, which includes mineral ions ( iron, calcium etc) and vitamins. Also we have to take in enough water (6-8 cups a day) and fibre to prevent deficient diseases and to maintain health.
in addition, note that the amount of food intake varies with age, sex, body status, daily activity etc. For example, teenagers and pregnant women should increase all necessary nutrients intake to ensure proper growth and development of ourselves or the baby.
Answer:
Therefore, 98% of the US population have no alleles for PKU
Explanation:
The Hardy-Weinberg equilibrium states that the amount of genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.
The Hardy-Weinberg equilibrium is expressed quantitatively using a mathematical equation known as the Hardy-Weinberg equation. the equation is given below:
p² + 2pq + q² = 1
also, p + q = 1
Given a pair of alleles, S and s with A dominant and a recessive
where p is the frequency of the dominant allele in the population,
q is the frequency of the recessive allele in the population,
p² represents the frequency of the (SS) dominant genotype,
q² represents the frequency of the (ss) recessive genotype,
2pq represents the frequency of the heterozygous genotype
From the given question,
q² = 1/10000 = 0.0001
q = 0.01
from p + q = 1
p = 1 - 0.01 = 0.99
p² = 0.98
Therefore, 98% of the US population have no alleles for PKU
Answer: A plant cell will have a cell wall, while a animal cell won’t.
Answer:
The correct answer is insight learning.
Explanation:
A kind of problem-solving or learning, which takes place instantaneously by comprehending the various aspects of an issue in spite of going through trial and error procedure is termed as insight learning. The given case is a clear illustration of insight learning. This form of learning takes place if one finds a novel way to solve an issue without the help of any other elements.
The individual in the given case used the help of a cut potato to collect the broken pieces of a lamp, which is an illustration of insight learning. The person has used his instinct and has not used any outside source for doing what he had done.
Answer:
Leaves are the site of the food making process called photosynthesis. In this process, carbon dioxide and water in the presence of chlorophyll (the green pigment) and light energy are changed into glucose which is sugar. This energy rich sugar is the source of food used by most plants.
