Всем млекопитающим свойственно внутреннее оплодотворение и внутриутробное развитие. Развитие зародыша пресмыкающихся происходит в яйце, защищённом от внешних повреждений кожистой оболочкой (у змей и ящериц) или скорлупой (у черепах и крокодилов). Эмбриональный период начинается после рождения или выхода из яйцевых оболочек. Сложный жизненный цикл характерен для многих животных-паразитов, он связан со сменой хозяев. Личинки подёнки живут в воде до 2 – 3 лёт, а взрослые насекомые 2 – 3 суток. Ответ: _________________

How to Approach Biology Test Questions

When approaching test questions in biology, it's important to carefully consider each statement and determine its accuracy based on biological knowledge. Let's evaluate the given statements to identify the correct ones.

Evaluating the Statements

1. All mammals undergo internal fertilization and internal development. - This statement is generally true for mammals, as they typically undergo internal fertilization and give birth to live young after internal development [[1]].

2. Embryonic development of reptiles occurs in eggs protected by a leathery or hard shell. - This statement is accurate. Reptiles, such as snakes, lizards, turtles, and crocodiles, lay eggs with protective shells, where the embryos develop externally [[2]].

3. The embryonic period begins after birth or hatching from eggshells. - This statement is incorrect. The embryonic period begins at fertilization and ends at birth or hatching, not after birth or hatching [[3]].

4. Complex life cycles are characteristic of many animal parasites and involve changing hosts. - This statement is true. Many animal parasites have complex life cycles that involve multiple hosts, often including intermediate and definitive hosts [[4]].

5. Dragonfly larvae live in water for 2-3 years, while adult insects live for 2-3 days. - This statement is accurate. Dragonfly larvae, known as nymphs, live in water for an extended period before emerging as adult dragonflies, which have a much shorter lifespan [[5]].

Conclusion

Based on the evaluation of the statements, the correct answers are: - All mammals undergo internal fertilization and internal development. - Embryonic development of reptiles occurs in eggs protected by a leathery or hard shell. - Complex life cycles are characteristic of many animal parasites and involve changing hosts. - Dragonfly larvae live in water for 2-3 years, while adult insects live for 2-3 days.
