Answer:
a. True
Explanation:
One of the characteristics in reptile reproduction is that they are vertebrate animals and reproduce by eggs, that is, they are oviparous. Reptile eggs are quite similar to those we can find in birds and differ from those laid by amphibians and fish. This is because reptile eggs are amniotic, that is, they have a specific membrane that prevents the sequence of the egg.
The oviparous reproduction of reptiles stands out for the fact that the eggs they lay are specifically designed to survive without problems in arid conditions thanks to the amount of elements that compose it, we refer to the amniota egg. For starters, the shell is hard enough to protect the embryo, but at the same time it is permeable enough to allow the exchange of gases with the outside. The egg needs both water and nutrient reserves and normally these reserves are obtained through albumin. In addition to this, the egg has a sac that collects all the waste compounds and also has the amniotic sac with its amniotic fluid that serves as a buffer for the embryo.
The skin of reptiles resembles that of amphibians, as it is composed of two layers called dermis and epidermis.
Unlike amphibians, reptile skin does not have any type of glands to moisten it, which gives it a drier and harder skin that also makes it impervious to water.
The circulatory system in reptiles is VASCULAR, CLOSED, DOUBLE and INCOMPLETE, double because there are 2 blood circuits, the minor or pulmonary circulation (heart-lung-heart) and the major or systemic circulation heart-body-heart), it is vascular because the blood leaves the heart thro ugh the blood vessels, it closes because the blood never leaves the blood vessels, that is, it is not poured into large interoceanic spaces or blood lagoons, it is incomplete because the venous and arterial blood mix in the Only ventricle possess, however, in crocodiles (more evolved reptiles) by having 2 ventricles, the mixture of both blood persists, that is, there is a minimal mixture of both types of blood.
In all reptiles breathing is pulmonary. The lungs have partitions or partitions that offer a greater gas exchange surface and greater efficiency. Ophidiums, like snakes, only have the right functional lung, the left lung is atrophied. Sea turtles, in addition to lung breathing, have sewer breathing for this because their vascularized sewer takes the O2 that dissolves in the water.
