Describe how birds and reptiles both reproduce. describe two ways that birds and reptiles differ. use two particular animals as example in your description

They both produce eggs inside of shells, which contain the developing offspring.

After mating, the females of both groups produce eggs which envelope, nourish, and protect the developing offspring until they are ready to hatch. This is an adaptation that allows these groups to live their entire lives on land without having to return to the water in order to reproduce the way amphibians do.

All birds and most reptiles are oviparous, meaning that they lay their eggs outside of their bodies, in which the offspring develop until they hatch.

Some snakes are ovoviviparous, which means that after the mother produces the eggs, she retains the eggs until they hatch and she gives birth to live young. This is not the same as female mammals in which there is a uterus, an embryo, an amniotic sac, and a placenta.

Both birds, such as owls and eagles, and reptiles, such as snakes and lizards, reproduce with a unique kind of egg called the amniotic egg. An amniotic egg is a shelled egg in which an embryo develops. Birds are feathered and reptiles are scaled. Birds are endotherms (warm-blooded) and reptiles are ectotherms (cold-blooded).

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
