In metaphase I of meiosis I, the pairs of homologous chromosomes, also known as bivalents or tetrads, line up in a random order along the metaphase plate. The random orientation is another way for cells to introduce genetic variation.
Answer:
Red blood cells are adapted to their function by:
1) They contain haemoglobin - a red protein that combines with oxygen. they have no nucleus so they can contain more haemoglobin.
2) They are small and flexible so that they can fit through narrow blood vessels.
3) They have a biconcave shape (flattened disc shape) to maximise their surface area for oxygen absorption.
Hope this helps! :D

The correct option is ALDOSTERONE.
Angiotensin ll is one of the most potent sodium retaining hormones. It regulates aldosterone release from the adrenal cortex. The aldosterone hormone stimulates sodium re-absorption through mineralocorticoid receptors in the connecting and cortical segments of the collecting tubules.
Answer:
little pouches
Explanation:
the aleveoli are like small balloons, but not large ones. they exchange oxygen and carbon dioxide molecules (so they contain small amounts of air like a SMALL balloon, or in this situation a small pouch).
