The parts of the amniotic reptile egg include the amniotic fluid, the albumen, and the shell.
<h3>Parts of an amniotic reptile's egg</h3>
The various parts of amniotic reptile's eggs include:
- The external shell which serves as a protective layer
- The yolk which supplies energy to the embryo
- The albumen supplies the embryo with water and proteins
- The extra-embryonic membranes - the chorion, the allantois, and the amnion.
The chorion serves as a channel for gaseous exchange between the embryo and the environment.
The allantois partially functions as waste manager and in respiration. It stores nitrogenous wastes and gets rid of them as well as participates in gaseous exchange along with the chorion.
The amnion protects the embryo against mechanical shocks. It also protects the developing embryo from being dehydrated.
In other words, the 3 extra-embryonic membranes protect, facilitate gaseous exchange, and ensure that wastes are properly disposed of.

Parasitic.
you need to know each of these choices meaning so that it will be easier to solve such a problem.
parasitic means it consumes its host and leave it only exhausted adn maybe dead.
autotrophic is like plants, they can make their own food.
saprophytic means is called on an organism, especially fungi, that feeds on dead material only.
Answer:
The chance of a woman with an AB blood type and a man with an O blood type having a child with O blood is 0%.
Explanation:
A mother with blood type AB (AB) will pass either antigen A or antigen B to the offspring, while the father with blood type O (OO) will not pass any antigen.
The result of an AB X OO cross would be
Alleles O O
A AO AO
B BO BO
For this reason, the offspring of this couple will be
- <em>Blood type A (AO) 50%.
</em>
- <em>Blood type B (BO) 50%.
</em>
- <em>Blood type O (OO) none.
</em>
Heredity of blood type depends on the presence of surface antigens on the erythrocyte membrane. Blood type O occurs in persons whose red blood cells do not possess surface antigens A or B.
Surface antigens are what determine blood type, so
:
- <em>The presence of antigen A determines blood type A.
</em>
- <em>Blood type B depends on the presence of antigen B.
</em>
- <em>Blood type AB has both antigens.
</em>
Blood type O has no antigens, and for blood type O to manifest, it must have both alleles for O.
A mother AB and father O cannot have offspring with blood type O.

The process that is responsible for causing menstruation is called menstrual cycle. Menstrual cycle is the natural change that occurs specifically in the ovaries and uterus or in the female reproductive system that gives possibility to pregnancy. This process is required for the ovocytes to be produced, and also for the uterus to be prepared for pregnancy.
