Peter is 20 months old, weighs 28 lb, and he wants to eat the same food his older brothers do. No baby food for him; he is a big boy now! His mother is worried that this might not be an appropriate diet for a toddler and asked you, the nutrition student, to check it out. Be prepared for a challenge! It’s not easy to think about all the elements that make a healthful diet at the same time. You have to think about kilocalories, Acceptable Macronutrient Distribution Ranges (AMDR, which by the way are different for toddlers than for adults and adolescents), and watch iron (the most common dietary deficit in toddlers) and fiber intake. And that’s just the beginning. Adequate intake of fluids and electrolytes is also critical for a toddler’s health. Is your head spinning already? Let’s simplify the job by approaching each of the recommended Daily Values separately.
A balanced diet helps to prevent malnutrition in all of its manifestations as well as a number of noncommunicable diseases (NCDs) and illnesses throughout the life course.
What is Diet?However, there has been a change in dietary patterns as a result of increased production of processed foods, growing urbanization, and changing lifestyles.
Nowadays, individuals eat more meals that are heavy in calories, fats, free sugars, and sodium/sodium, and many people eat insufficient amounts of fruit, vegetables, and other dietary fiber-rich foods like whole grains.
Depending on individual characteristics (such as age, gender, lifestyle, and level of physical activity), cultural context, regionally accessible foods, and dietary habits, a diversified, balanced, and healthy diet will take on different compositions.
Therefore, A balanced diet helps to prevent malnutrition in all of its manifestations as well as a number of noncommunicable diseases (NCDs) and illnesses throughout the life course.

The breaking of a large organic molecule into smaller individual subunits involves multiple ________. dehydration synthesis reactions osmotic reactions hydrolysis reactions hydrosynthetic reactions
Answer:
hydrolysis reaction
Explanation:
Hydrolysis reactions are the reverse of condensation reactions. In a hydrolysis reaction, a larger molecule forms two (or more) smaller molecules and water is consumed as a reactant. Hydrolysis ("hydro" = water and "lysis" = break) involves adding water to one large molecule to break it into multiple smaller molecules.

A disputed paternity case! Hermione’s new baby has a blood type of O. Her blood type is B and Ron Weasley is A. Harry Potter (blood type AB) insists he is the child’s father. CAN THIS BE TRUE???!
Answer:
No becuase one of the parents needs to have type O
Explanation:
No, this cant be true because in order for a child to have O blood type parents must have a recessive allele "[tex]i[/tex]".
What type of alleles are blood types?An allele is a particular form of genetic information that can be found in our DNA at a particular spot on a certain chromosome. This form of genetic information is known as an allele.
Codominant alleles in humans are responsible for determining blood types. There are three distinct alleles, and they are denoted by the letters IA, IB, and i. The IA and IB alleles both have co-dominant inheritance, but the i allele has a recessive inheritance pattern. Type A, type B, type AB, and type O are the four different human phenotypes that are possible for the blood group.
Therefore, in order for a child to have O blood type parents must have a recessive allele "[tex]i[/tex]"

Hemophilia is an X-linked trait caused by the allele h. About 1 in 10,000 males (0.0001) has hemophilia. The frequency of the h allele in males is therefore
.
Answer : 0.0001
Explanation:
Since males only have 1 X chromosome, the number of males with h alleles should be equal to number of males with Haemophilia and therefore the frequency of males with Haemophilia must be equal to the frequency of h alleles on X chromosome.

Assume for the purposes of this problem that the order of and distances between three linked genes are the following: unc-32 10mu vab-7 20mu dpy-17 What is the probability of obtaining a phenotypic unc-32 vab-7 offspring from a cross between a heterozygous fly(unc-32 vab-7 dpy-17/ ) and the triple recessive nematode
From the distances between genes and their order, it is possible to get recombination frequencies per region (simple and double recombination frequencies). The probability of obtaining a unc-32 vab-7 + offspring is 0.09 = 9%.
---------------------
We are usually asked to get the order of genes in a chromosome. To do so, we need to get the distances between genes. And to get distances between genes, we need to get their recombination frequency.
When three genes are involved, we get the distances by taking the recombination frequency, P, per region.
We talk about regions, R, when we are making reference to the space between two genes.
Gene 1 -----(R1)----- Gene 2 --------(R2)------ Gene 3
P1 P2
P1 = recombination frequency between Gene 1 and Gene 2P2 = recombination frequency between Gene 2 and Gene 3⇒ P1 = (SR + DR) / N
⇒ P2 = (SR + DR)/ N
Where:
SR is the number of simple recombinants in each region, DR is the number of double recombinants in each region, and N is the total number of individuals.The genetic distance will result from multiplying that frequency by 100 and expressing it in map units (MU). One centiMorgan (cM) equals one map unit (MU).
In the exposed problem, we need to do the inverse way. We already have the order and distances between genes, and we need to get the recombination frequency, P.
We know that the order of genes is as follows,
unc-32 ------------- vab-7----------------- dpy-17
Distances are:
Region 1 = 10 MURegion 2 = 20 MUWe need to get the probability of obtaining a phenotypic unc-32 vab-7 + offspring from a cross between a heter0zyg0us fly (unc-32 vab-7 dpy-17/ + + + ) and the triple recessive nematode (unc-32 vab-7 dpy-17 / unc-32 vab-7 dpy-17).
Cross:
unc-32 vab-7 dpy-17 / + + + x unc-32 vab-7 dpy-17 / unc-32 vab-7 dpy-17
To get the genotype unc-32 vab-7 + , a simple recombination, SR, must occur in region 2.
So we need to get the simple recombination frequency in Region 2.
To do so, first we need to clear the following equation
Distance between vab-7 dpy-17 = P2 x 100 = 20 MU
20MU = P2 x 100
P2 = 20 / 100
P2 = 0.2
The recombination frequency in region 2 (P2) is 0.2.
Now, we need to get the simple recombination frequency in this region.
P2 = (SR + DR) / N
P2 = Simple recombinants Frequency + Double recombinants Frequency
R1 = 10 MUR2 = 20 MUDouble recombinants Frequency = 10% x 20% = 0.1 x 0.2 = 0.02P2 = Simple recombinants Frequency + Double recombinants Frequency
0.2 = Simple recombinants Frequency + 0.02
Clearing the equation,
Simple recombinants Frequency = 0.2 - 0.02 = 0.18
Simple recombinant frequency in region 2 will produce the following two chromosomes,
unc-32 vab-7 ++ + dpy-17So half of this frequency will produce one chromosome, and the other half will produce the other chromosome.
unc-32 vab-7 + ⇒ 0.09+ + dpy-17 ⇒ 0.09So, the probability of obtaining a phenotypic unc-32 vab-7 + offspring is 0.09 = 9%.

What happens if a cell is unable to divide by mitosis
Answer:
When this happens, sometimes the cell commits a special type death is called apoptosis. Apoptosis, otherwise known as programmed cell death, ensures that if mitosis goes wrong and cannot be fixed, the cell does not continue to divide, as this would lead to the production of mutant cells that might cause problems.
