Question

D) regeneration Questions 3 through 6 refer to the following: Diagram A Fertilized Amphibian (frog egg) Diagram B Developing Bird Embryo 3) — 4) Which statement best describes where these eggs will continue to develop? A) Both eggs will develop on land. B) Egg A will develop on land and egg B will develop in water. C) Egg A will develop in water and egg B will develop on land. D) Both eggs will develop in water. If these eggs were each compared to the egg of placental mammal, the mammal's egg would be A) larger than A but smaller than B c) larger than either A or B B) about the same size as B D) much smaller than either A or B In diagram B, structure 1 encloses a fluid. The function of this fluid is to A) provide nourishment to the embryo B) provide the embryo with a liquid to drink C) protect the embryo from physical shock D) filter out the damaging radiation

all questioan are from the diagram

Answer 1

Q.3. Answer- c) Egg A will develop in water and egg B will develop on land

Explanation- amphibian like frog lay egg in water and have aquatic larvae that develops into terrestrial adult frog after metamorphosis. So that egg A will develop in water.

Bird egg develops on land in nest or any protected shell where in warm and favorable temperature embryo develops.

Q.4. Answer- D) much smaller than either A or B

Explanation- placental mammals egg is smaller than frog and bird egg because egg of placental mammal have very little yolk because developing embryo gets all nutritional supplements from mother. The amphibian and birds egg are larger due to larger yolk content that nourishes developing embryo until hatching.

Q.5. Answer- C) protect the embryo from physical shock

Explanation- In diagram B, structure 1 encloses a fluid that is known as amniotic fluid. This amniotic fluid surrounds the embryo and function as shock absorber.

Q.6. Answer- B) Egg A was fertilized externally and egg B was fertilized internally

Explanation- frog egg is fertilized outside female body and bird egg is fertilized inside female body. Frog female lays eggs in water and at the same time Male releases sperm to fertilize egg. In birds Male brings his sperms to female cloaca and fertilizes egg in female body.
