Answer:
Presence of papillary muscles
Explanation:
- Papillary muscles are structural components of the ventricles.
- They are attached to the cusps of the mitral and tricuspid valves through connective tissue strings known as the cordinae tendeneae (heart strings).
- These muscles prevent the prolaspse of these valves during ventricular systole.
- Although they differ in number i.e. two in left and three in right ventricle, papillary muscles are present in both ventricles.

Answer:
Tilapia is one of the most productive and internationally traded food fish in the world. The production of farmed tilapia is among the fastest expanding food sectors in the world. Nile tilapia ( Oreochromis niloticus) is the most cultured freshwater species among the farmed tilapia and contributes about 71% of the world total tilapia production.
Tilapia is one of the most important farmed fish species worldwide (FAO 2018) and an important source of protein (Fitzsimmons 2000;Hai 2015). Due to its sequenced genome (Conte et al. 2017), easy reproduction, efficiency in adapting to diverse diets, high resistance to diseases and handling practices, and high tolerance of a wide variety of husbandry conditions, it is considered an ideal model in toxicological research.

Answer:
Imarie uses a microscope to study different prokaryotic and eukaryotic organisms. Which of the following statements describes how the prokaryotic cells appear compared to the eukaryotic cells? The prokaryotic cells are much smaller than the eukaryotic cells.
Archaea differ from bacteria in that archaea lack peptidoglycan.
<h3>
What about archaea and bacteria?</h3>
- Although archaea lack internal membranes, they do have a cell wall and swim by using flagella.
- The difference between bacteria and archaea is that bacteria have an ester-linked cell membrane, while archaea have an ether-linked cell membrane.
- Organelles and other internal membrane-bound structures are not present in the cells of bacteria and archaea.
- In contrast to eukaryotes, bacteria and archaea do not have a nucleus that separates their genetic material from the rest of the cell.
- Similar to Eubacteria, Archaea have a polysaccharide and glycoconjugate-rich cell wall.
- The strong cell borders that archaea form despite not having peptidoglycan make them resistant to high internal osmotic pressure.
