Well the male bird is a dominant (long beak) and the female is a recessive(small beak.) we can assume that the female birds genotype is ii and the male birds genotype is LL or Li. When it comes to the offspring we can assume that the offspring would have a long beak. The offspring would either have the dominant (father) genes.

A recent study of the marine hawksbill turtle's stomach contents revealed that sponges constitute a major portion of their diet.

Answer:

These structures that protect the sponges from most predators, but not turtles, are spicules.

Explanation:

Sponges skeleton is composed of calcium carbonate and siliceous micro-structures called spicules. Their morphology is so varied that it is used in taxonomy for identification and classification.

There are different kinds of spicules:

- Monoaxonic spicule: needle-shaped, straights or curves

- Tetraxonic spicules: they have four prolongations

- Triaxonic or Hexaxonic spicules

- Poliaxonic spicules

Two terms can be applied to any of these spicules kinds:

- Megaspicules: They are elongated and compose the main architecture of the sponge skeleton

- Microspicules: Variable in shape and size, with ancillary functions

Sponges have few predators thank to the spicule structures and their high toxicity. Many of them are capable of perforating soft tissues and producing urticant substances.

Oxygen and Carbon Dioxide exchange as a result of the interaction of which two body systems

miskamm [114]

Answer:

Explanation:

The circulatory system includes the blood that has picked up the carbon dioxide from all of the respiring tissues and who also delivered oxygen to them to continue respiring.

The blood will then reach the lung where the carbon dioxide that the tissues released is exchanged for oxygen in the alveoli.

* Blood cells isn't an organ system which makes 1 incorrect.

* Digestive system will in no way bring the blood to the lungs or away from it. This is the circulatory system's job. So 2 is incorrect.

*Lastly, lungs are organs and the question asks for organ systems. So 3 is incorrect.
