very true. i know because i suffer with ni polar myself.
Producer to consumer? I don't know this one
Predator to prey
For part A you'd find out 40 percent of 15 so 0.40 x 15. That = 6 since the price was raised you'd do 15 + 6 which is 21.

Explanation:
Cardiac muscles, also known as myocardium, are one of the three types of muscles found in the heart (the other two being skeletal and smooth muscles). Cardiac muscle cells are striated and branched in structure, with only one nucleus located centrally i.e. mono-nucleated.
Unlike the skeletal muscles, cardiac muscles are involuntary muscles controlled by certain parts of the brain. The cells that make up the cardiac muscles are connected to one another by structures called intercalated discs. Also, cardiac muscle cells contract spontaneously i.e. internally. Hence, options B and C are correct
Answer:
Protein molecules.
Explanation:
Protein, highly complex substance that is present in all living organisms. A chain of amino acid residues is called a polypeptide which is a bond form by the carboxylate ion on one end and the -Nh2 on the other end via condensation reaction.
Proteins are large biological molecules (macromolecules), which consists of one or more long chains of amino acid residues. Proteins perform certain functions in organisms like Enzymes - catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells, transporting molecules from one location to another etc.
Proteins differ from one another in their amino acid sequence, which is dictated by the nucleotide sequence of their genes, which usually results in protein folding into a three-dimensional structure that determines its activity.
