The answer is e. Calcitonin, Aldosterone and Atrial natriuretic peptide.
The calcitonin is a hormone secreted by the thyroid gland. Calcitonin is involved in the regulation of the levels of calcium and phosphate in the blood. Aldosterone is a hormone secreted by the adrenal gland. It is essential for maintaining the store of sodium in the kidney, salivary glands, sweat glands and colon. Atrial natriuretic peptide (ANP) or Atrial natriuretic factor (ANF) is a peptide hormone synthesized, and secreted by cardiac muscle cells in the heart. ANP is involved in the regulation of sodium levels in the cells of the heart.
The components<span> of </span>animal cells are centrioles, cilia and flagella, endoplasmic reticulum, golgi apparatus, lysosomes, microfilaments, microtubules, mitochondria, nucleus, peroxisomes, plasma membrane and ribosomes.<span>The centrosomes is where microtubules are made. During </span>cell<span> division (mitosis), the centrosome divides and the two </span>parts<span> move to opposite sides of the dividing </span>cell<span>. The centriole is the dense center of the centrosome. cytoplasm - the jellylike material outside the </span>cell<span> nucleus in which the organelles are located. Thats what i found when i researched about animal cells. Hope this helps, I put what i know and reaserched the rest.</span>
<span>The most primitive vertebrates whose reproductive pattern includes the amniotic eggs are the reptiles.
An amniotic egg is filled with amniote, which are these membranes that have fluid in them. They serve to protect the embryo and enable it to survive any harsh conditions that may harm it. These cells have protein shells as well as calcium that provide further protection.
