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:
In the freshwater food web,
the relationship between the minnow and the water fleas can be described as <u><em> Predator-prey relationship</em></u>
Explanation:
A food web can be described as a diagram which shows multiple food chains. It represents the 'predator-prey' relationship in an ecosystem.
The freshwater food web will described all the predator-prey relationships in the fresh water.
The minnows in the fresh water feed on larval fishes, mosquito larvae and water fleas. Hence, minnows will be the predators and water fleas will be the preys. So, these organisms will show a predator-prey relationship.
Red blood cells exchange carbon dioxide for oxygen
Pikachurin, also known as AGRINL and EGF-like, fibronectin type-III and laminin G-like domain-containing protein, is a protein that in humans is encoded by the EGFLAM gene
Answer:b. cellulose; cell walls of plants
Explanation: polysaccharides are polymers of monossacharides.they are the most abundant organic substance.it is found in the cell walls of plants . cellulose is a linear polymer of glucose residues.cellulose is an important component in the diet of herbivores and omnivores.they do not produce the cellulase enzyme for digesting cellulose.as a result,they depend on symbiotic relationship with bacteria and protozoa found in their stomach to produce cellulase.
