The correct answer is C. Body parts are created during the first trimester, and they complete their development during the third.

The first 12 weeks of pregnancy is the first trimester. This trimester is also regarded as the embryonic stage because developing baby is called embryo. During this trimester, body parts such as eyes, ears, the nasal passage, arms, legs, hair follicles, mouth are formed. The sex organs are developed by the end of this trimester.

The third and final trimester starts 25 weeks after pregnancy. All the body parts of the baby formation completed. The movement of the fetus in the womb increases.

Answer:

Membrane bound cell organelles

Explanation:

A prokaryotic cell lacks a membrane defined nucleus and all the membrane-bound organelles. A eukaryotic cell has a membrane-bound nucleus and other membrane-bound organelles such as mitochondria, chloroplasts, endoplasmic reticulum, lysosomes, Golgi apparatus, etc.

To determine if a cell is a prokaryotic or eukaryotic, one can look for the nucleus and the membrane-bound organelles. If the cell has a nucleus and membrane-bound organelles, it is a eukaryotic cell. The absence of these structures makes it a prokaryotic cell.

Animals with a three-chambered heart would include:_______

Setler79 [48]

Animals with a three-chambered heart would include Amphibians.

Amphibians have three-chambered which comprises of two Atria and one ventricle. Examples of Amphibians include Frog, Toads, Salamanders.
In Amphibians heart blood from the single ventricle travels to the lungs, skin, and body, where it is oxygenated. Before being pumped out of the heart, deoxygenated and oxygenated blood are mixed in the ventricle.
This is because the Amphibians have low rate of metabolism and thus requires less oxygen for their metabolism.
As a result heart's load to deliver oxygenated blood to body is lowered.

Thus, from the above pointers we can conclude that only Amphibians from the option have three-chambered heart.
