Haemoglobin is an iron rich pigment that carries oxygen
S waves are slower than P waves and they can only travel through solid rock. S waves move the particles it pushes through up and down or side to side (perpendicular to the motion of the S waves energy).
Answer:
D.DNA-mRNA-Amino Acid-Protein-Trait
Explanation:
The relationship between DNA and the trait of an organism involves a process called GENE EXPRESSION. DNA is a molecule that contains information needed for the survival of an organism. However, this information must be expressed in order to be used.
The process of gene expression involves two major processes namely: transcription and translation. Transcription involves the synthesis of mRNA from DNA template while translation involves the synthesis of amino acid sequence from mRNA. The amino acid sequence encodes PROTEIN, which determines the TRAIT of an organism.
Based on this explanation, the correct sequence that best represents the relationship between DNA and the traits of an organism is: DNA-mRNA-Amino Acid-Protein-Trait
Answer: e. prokaryotic cells lack nuclei.
Explanation: Prokaryotes are unicellular (single-cell) organisms that lack well developed cell internal membrane-bound structures or organelles. They do not have a nucleus but generally, they have a single chromosome that possess a double-stranded DNA located in an area of the cell called the nucleoid. Most prokaryotes have a cell wall outside the plasma membrane.
