C
Explanation:
I just did it
Answer: The correct answer is nitrogen, calcium and phosphorus.
Explanation:
Elements are defined as the substances which are made out of same type of atoms. For Example: Hydrogen, Oxygen etc..
Human body is made up of various types of elements in which 6 are most abundant.
Almost 99% of the mass of human body is made up of mainly six elements. They are oxygen (O), carbon (C), hydrogen (H), nitrogen (N), calcium (Ca) and phosphorus (P).
About 0.85 % of mass of human body is composed of other 5 elements which are potassium (K), sulfur (S), sodium (Na), chlorine (Cl) and magnesium (Mg).
Hence, the correct answer is nitrogen, calcium and phosphorus.
The excretory system is responsible for removing all of the following from the body excep t
A. Toxic Waste B. Gaseous Waste C. Dissolved molecules D. Cells
Answer:
D. Cells
Explanation:
The excretory system consists of organs that help the body to get rid of excess and waste materials from the body, and also helps in maintaining internal homeostasis in the body. These organs include the large intestine, skin, lungs, kidneys. Most of the wastes are products of metabolism. These waste materials that are no longer useful to the body could be in liquid or gaseous form. Examples of substances removed from the body by the excretory system are urine, feces, sweat etc.
Cells are not part of the substances removed by the excretory system.
B) the complete set of an organism's polypeptides
C) the complete set of a species' polypeptides
D) a karyotype
E) the complete set of an organism's genes
The option defines a genome the complete set of an organism's genes.
The correct option is E.
A genome refers to the entire set of genetic material or genes present in an organism. It includes both the coding and non-coding regions of DNA that make up an organism's genetic instructions. Genes are segments of DNA that contain the information necessary for producing specific proteins or functional RNA molecules. The genome of an organism encompasses all the genes and genetic elements that contribute to its characteristics, traits, and biological functions.
Option A is incorrect because a cell's polypeptides represent the proteins produced from its genes, but they do not encompass the complete set of an organism's genes. Option B is incorrect because while it mentions the complete set of an organism's polypeptides, it does not encompass the non-coding regions of the genome.
Hence , E is the correct option
