Answer: D. some components of the cycle are used as building blocks for certain anabolic pathways.

Explanation:

The citric acid cycle or Kreb's cycle is the part of the cellular respiration. It is a sequence of chemical reaction which is used by all the aerobic organisms so as to store energy by the process of acetyl CoA oxidation derived by the process of fats, proteins and carbohydrates into forms like carbon dioxide and adenosine triphosphate (ATP).

The acetyl CoA is used in the process of synthesis of fatty acids. The citrate is used for the synthesis of cholestrol. The oxaloacetate and alpha ketogluterate are used for the synthesis of aminoacids. Succinyl CoA is used for the synthesis of poryphrins and fatty acids.

A heterozygous genotype may consist of one normal allele and one mutated allele, or two distinct mutated alleles.

The missing options of the question are:

  1. Yy ´ yy
  2. YY ´ yy
  3. Yy ´ Yy
  4. yy ´ yy

The cross between parent plants if one is heterozygous for yellow pods and the other is homzygous for green pods - Yy yy.

DerKrebs [107]
<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2><h2>KAROTYPE:</h2>

This is the picture of karyotype. Karyotype is a collection of a Individuals chromosome. Like pairs are separately represented from the unlike pairs, It is generally used to study the chromosomes and the abnormalities found in the number of chromosomes.

<h2>_____________________________________</h2><h2>CHROMOSOMAL NUMBER 18:</h2>

Every chromosomal pair seems fine, except the chromosomal pair number 18. Because as you ca see that it has 3 chromosomes instead of 2. This impairment in the chromosomal pair is called trisomy as it has 3 chromosomes.

<h2>_____________________________________</h2><h3>TRISOMY 18:</h3>

Trisomy 18 is also called Edwards syndrome. It is a chromosomal condition associated with abnormalities in more than one part of the body. Individuals with trisomy 18 often mature slowly than normal fetus before birth and they have lower weight at the time of birth as compared to the other children.

Answer:

D. The system provided an organized way to classify living things and it has been able to grow and develop. There is a place to enter new organisms as they are discovered or new evidence occurs

Explanation:

Carolus Linnaeus is a Swedish Botanist is universally referred to as the FATHER OF TAXONOMY because of his contribution to the development of a system of naming and classifying species, which is still globally recognized today. Linnaeus proposed the binomial nomenclature system which uses two of the hierarchical classification to name organisms i.e. genus and species. For example, humans are Homo sapiens; Homo (generic name), Sapien (specific name).

Modern scientists later modified Linnaeus classification by adding new ranks in order to accommodate new species and removing incorrectly classified organisms but Linnaeus classification remains the foundation. One important modification was the inclusion of a new taxon called DOMAIN.
