In addition to endocrine glands, some organs whose functions are primarily nonendocrine also produce hormones. these endocrine tissues include heart and kidneys.
<span>
The heart can act as an endocrine organ by releasing natriuretic peptides that lower the blood pressure. Those are an A-type natriuretic peptide (ANP) from the from stretched atria and B-type natriuretic peptide (BNP) from the ventricles.</span>
<span>
The kidney secretes two hormones: erythropoietin (EPO) which increase the production of red blood cells and calcitriol (active vitamin D3) which promotes the absorption of Ca and its release from the bones.</span>
Answer:
The correct answer is - B. lower environmental availability of CO2
Explanation:
In C4 plants they have developed a mechanism for the CO2 concentrating and leads to the lower environmental availability of CO2 for these plants, C4 to avoid photorespiration.
These plants tend to be found in drier environments with high sunlight levels and not thrive in a cool shady forest due to this mechanism that results in low availability of carbon dioxide.
C. There are two types of glaciers: Alpine and Continental
The Rules of Protein Structure. The function of a protein is determined by its shape. The shape of a protein is determined by its primary structure (sequence of amino acids). The sequence of amino acids in a protein is determined by the sequence of nucleotides in the gene (DNA) encoding it.
