Question

Очень срочно!!!!!!!!!!!!!!!!!!!!!!!! Какие из перечисленных утверждений являются верными? Самцы некоторых амфибий в период размножения выделяют феромоны, привлекающие самок. Все амфибии размножаются в воде. Некоторые амфибии выкармливают потомство своей кожей Амфибии видят только движущиеся объекты. Высокая «посадка» глаз на голове амфибий объясняется их способностью проталкивать пищу в ротовой полости с помощью глазных яблок.

Answer 2

Which of the following statements are true?

1. Male amphibians release pheromones during the breeding season to attract females. 2. All amphibians reproduce in water. 3. Some amphibians nourish their offspring through their skin. 4. Amphibians can only see moving objects. 5. The high position of amphibians' eyes on their heads is due to their ability to push food into their oral cavity using their eyeballs.

Let's verify each statement using search results:

1. Male amphibians release pheromones during the breeding season to attract females. - This statement is true. Male amphibians, such as frogs and salamanders, often release pheromones to attract females during the breeding season. These pheromones are chemical signals that help in mate selection and reproduction. [[1]]

2. All amphibians reproduce in water. - This statement is true. Amphibians have a unique life cycle that involves reproduction in water. They typically lay eggs in water, and the eggs hatch into aquatic larvae, such as tadpoles. These larvae then undergo metamorphosis and develop into terrestrial adults. However, it's worth noting that some amphibians, like certain species of lungless salamanders, have evolved to reproduce entirely on land. [[2]]

3. Some amphibians nourish their offspring through their skin. - This statement is true. Some amphibians, such as certain species of frogs, have the ability to absorb water and nutrients through their skin. This adaptation allows them to provide nourishment to their developing offspring. For example, female poison dart frogs lay their eggs on land, and the male guards and moistens the eggs by urinating on them. The developing tadpoles then absorb nutrients through their skin. [[3]]

4. Amphibians can only see moving objects. - This statement is false. Amphibians, like other vertebrates, have the ability to see both moving and stationary objects. Their visual capabilities vary among species, but they are generally capable of perceiving stationary objects as well. [[4]]

5. The high position of amphibians' eyes on their heads is due to their ability to push food into their oral cavity using their eyeballs. - This statement is false. The high position of amphibians' eyes on their heads is not related to their ability to push food into their oral cavity using their eyeballs. The positioning of their eyes is primarily related to their visual field and the need to detect predators and prey in their environment. [[5]]

In summary, the true statements are: - Male amphibians release pheromones during the breeding season to attract females. - All amphibians reproduce in water. - Some amphibians nourish their offspring through their skin.
