koban [17]

Answer:

Thoracic cage and vertebral column.

Explanation:

The bones of the head and the bones that make up the trunk of a vertebrate organism form the <em>axial skeleton. </em>

In the case of humans the axial skeleton consists of a total of 80 bones which are broadly organized into 6 parts:

1. Bones of the skull

2. Middle ear ossicles

3. Hyoid bone

Which three structures are found in both prokaryotic and eukaryotic cells? cytoplasm, endoplasmic reticulum, DNA ribosomes, DNA,
hoa [83]

Answer and Explanation:

Eukaryotic and prokaryotic cells share the presence of:

- cytoplasm, in which their organelles are dispersed.

-the cell membrane, which covers the cell by shaping and regulating the passage of substances (in and out of it).

- ribosomes, are the place where proteins are synthesized.

In addition, both cells possess DNA although this is not the same in both. In the eukaryotic cell it is linear and is within the nucleus, while in the prokaryotic cell it is circular and does not have a true nucleus that protects it.

Prokaryotic bacteria are surrounded by a ____________ that contains the ____________ to regulate the entry and exit of materials
lukranit [14]

Prokaryotic bacteria are surrounded by a cell membrane that contains the transport proteins to regulate the entry and exit of materials through the cell, the cell wall to help maintain cell shape and structure, and the capsule, which aids against drying out and protects bacteria from a host's immune system.

<h3><u>Explanation:</u></h3>

Bacteria are the prokaryotic organisms that are found in every part of Earth. These organisms do have an interesting ultrastructure. The coverings of the bacteria are three in layer. They are

A. The outer capsule.

B. The middle cell wall.

C. The inner cell membrane.

The capsule is the outermost covering of bacteria that is formed of different slimy materials. These materials contains hygroscopic substances which can absorb water from the surroundings even when the water concentration in outside is very very low. This layer of protection outside bacteria help them to protect themselves against drying out at dry conditions.

The middle cell wall is formed of polymers of N acetyl glucosamine and N acetyl muramic acid. This layer is chitin in nature and is strong enough to maintain the shape and size of bacteria irrespective of outer conditions.

The innermost layer of bacteria is cell membrane which is formed of proteins and lipids bilayer and this cell membrane contains different transport for proteins which help in transport of different substances like water and nutrients inside the cell by means of active transport or passive diffusion.
