Macronutrients are nutrients that contain inorganic components. a. True b. False

emmasim [6.3K]3 years ago

This is false, as macronutrients are all made of organic components. Macronutrients are carbohydrates, fats, and proteins. The most basic unit for carbohydrates is glucose. Glucose is an organic molecule with a chemical formula of C6H12O6 which then is broken down by the body to convert it to energy (in the form of ATP). Fats or triglycerides are comprised of fatty acids and a glycerol backbone which can also be used by the body for energy or can be stored for later use. Proteins on the other hand are functional molecules wherein the basic unit for proteins is the amino acid. Proteins are exemplified because they contain nitrogen (CHON). All of which can be used as energy and has specific caloric value per gram (4 kcal for every gram of protein and carbohydrates and 9 kcal for every gram of fat).

Micronutrients are usually inorganic compounds with no caloric value. Usually these micronutrients are essential for maintaining biochemical pathways in the body. For instance, niacin and riboflavin are vitamins that are needed in the production of NAD and FAD which are important for reduction-oxidation reactions in the body (i.e. tricarboxylic acid cycle and electron transport chain).

ANTONII [103]

Which of these values would most likely be the heritability of body mass index (BMI) in a developing country with a large gap between nutrition and health care available to the rich and poor?

a. 0.33

b. -0.88

c. 0.99

d. 0.0001

e. 1.3

Answer:

a. 0.33

Explanation:

Body Mass Index is defined as the measure of fat depending on the height and weight of individuals. It is being calculated as: BMI=\frac{mass_{kg}}{height_{m^2}}

The most likely heritability of body mass index(BMI) in a developing country with a large gap between nutrition and health care will be 0.33.

These is because in developing countries especially countries experiencing rapid economic growth as illustrated by the annual GDP growth rate are likely to have widely ranging lifestyles due to influences of the burgeoning economy, Therefore, there are greater chances for the rich  to have access to the basic requirements and necessities of life whereas the poor are limited with either low or no access to adequate nutrition and health care.

In all cells, separation of replicated chromosomes is a prerequisite for cell division. However, the mechanism of chromosome sep
Ipatiy [6.2K]

1. two copies of the duplicated chromosome are attached at their centromeres before separating

2. chromosomes replicate before cell division

3. chromosome separation begins at the origin of replication on DNA

4. Before separation duplicated chromosomes condense; nuclear envelope fragments permitting chromosome separation

5. replicated chromosomes separate by attaching to some other structural feature of the cell

Explanation:

In the given question, the DNA replication steps of both prokaryotes and eukaryotes are provided in which some are common to both eukaryotes and prokaryotes and some are unique to the prokaryotes and eukaryotes.

<u>Eukaryotes </u>

1. Option-4 as the nuclear envelope is present in eukaryotes only.

2. Option-1 as centromere allows the kinetochores bind to the centromere which separates the chromosome.

<u>Bacteria </u>

1. Option-3 as DNA replication process separates the strand of the DNA.

<u>Both </u>

1. Option-5 as the chromosomes separate by other structures like microtubules

2. Option-2 as genetic material to be passed on to the generation must be replicated.

Can anyone tell me the ratio of the genotype and phenotype ???
iogann1982 [59]
<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2><h2>_____________________________________</h2><h2>Phenotype:</h2>

It is the physical appearance of the trait, whether the person has smooth chin or cleft chin.

<h2>Genotype:</h2>

A genotype refers to the genetic characteristics of an organism's trait, if it is heterozygous or hom.ozygous, recessive or dominant.

<h2>_____________________________________</h2><h2>Alleles:</h2>

Cleft chin C is dominant over smooth chin c

<h2>Genotypes of Parents:</h2><h3>FATHER:</h3>

Father has smooth chin thus, it is hom.ozygous recessive i.e. cc

<h3>MOTHER:</h3>

Mother has cleft chin, since cleft chin is dominant there are two possibilities of her genotype,

                           Heterozygous Dominant : Cc

                           Hom.zygous Dominant : CC

but if we cross the hom.zygous fominant mother to hom.ozygous recessive father we will get all the offsprings with the same genotype phenotype so it is not possibile, So the mother is HETEROZYGOUS DOMINANT Cc

<h2>_____________________________________</h2><h2><u>Question</u>:</h2><h2>_____________________________________</h2><h2>Genotypes of Parents:</h2>

FATHER: cc (Hom.ozygous Recessive)

MOTHER: Cc (Heterozygous Dominant)

<h2>_____________________________________</h2><h2>Punnet Square:</h2>

Picture attached!

Picture no 1: it is the cross between hom.ozygous recessive father and hom.ozygous dominant mother and all the offsprings are same both phenotypic and genotypic way so IT IS NOT POSSIBILE

Picture no 2: Its cross between hom.ozygous recessive father and heterozygous dominant mother and there are hybrid and pure recessive both type of offsprings present thus IT IS POSSIBLE!

<h2>_____________________________________</h2><h2>Genotype Ratio of the Offspring:</h2>

Hybrid : Pure Recessive

2 : 2 or 1 : 1

<h2>_____________________________________</h2><h2>Phenotype Ratio of the Offspring:</h2>

Cleft Chin : Smooth Chin

2 : 2 or 1 : 1

<h2>_____________________________________</h2><h2>Best Regards,</h2><h2>'Borz'</h2><h2 />
