Describe the cell membrane, cell wall, nucleus, and cytoplasm. which of these structures are you likely to find in a prokaryotic
Morgarella [4.7K]

Answer:

you can see below

Explanation:

Basic Definitions:

Cell Membrane = the semi-permeable structure that surrounds the cell and keeps all of the cells organelles from exploding everywhere.

Cell Wall = the rigid 'armor' of the cell that surrounds it after the membrane. Usually made up of cellulose and ONLY found in plant cells.

Nucleus = A really dense organelle of the cell usually surrounded by two membranes. They contain and protect your genetic material. Basically everything that makes you, you.

Cytoplasm = The watery, salty, and protein filled 'soup' that fills the cell. All organelles float happily in this.

Now Specific Locations:

Eukaryotic cells

have plasma membranes

please mark me brainliest or mark me thanks at leat

only have cell walls if the cells are plants.

They do have a nucleus.

They have cytoplasm

Prokaryotic cells

have plasma membranes

cell walls are usually chemically complexed.

don't have a nucleus

have cytoplasm

Animal cells

only have the plasma membranes.

No cell wall

have a nucleus

have cytoplasm

Plant cells

have both the cell wall

and have a plasma membrane

have a nucleus

have cytoplasm

Hatshy [7]
<h3><u>Answer;</u></h3>

Rock

<h3><u>Explanation</u>;</h3>
  • Rock is a naturally occurring solid mixture of one or more minerals or organic matter.
  • <em><u>Rock is a solid mixture of crystals of one or more minerals, or organic matter. </u></em>
  • <em><u>Rocks are classified by how they are formed, their composition, and texture. </u></em>Rock has been an important natural resource as long as humans have existed.
  • The rock cycle is the series of processes in which a rock type changes from one type to another.

According to the fluid mosaic model of membrane structure, proteins of the membrane are mostly
ioda

Answer:

Embedded in a lipid bilayer. (Ans. C)

Explanation:

Fluid mosaic model explains different observations such as the structure of functional cell membranes. According to this model, there is a thin polar membrane composed of a two-layer of lipid molecules called lipid bi-layer or phospholipid bi-layer in which proteins molecules are embedded. This layer provides fluidity and elasticity to the membrane structure.

These membranes form a continuous barrier around all cells and they are a flat sheet in structure. The lipid bilayer is working as a barrier that keeps proteins, ions and other molecules where they are needed to be and preventing diffusing them to other areas. They are impermeable to most hydrophilic molecules. They are particularly impermeable to ions, which allow cells to regulate pH and salt concentration in membrane through the transport ions across their membranes using proteins knows as ion pumps.

Many organisms possessing many different lipases produce positive results on tributyrin agar. Is the inability of this medium to
Gekata [30.6K]

Answer: See explanation below

Explanation:

Tributyrin agar Is the inability of this medium to distinguish between these different enzymes a weakness in its specificity or its sensitivity.

Lipases break down lipids (fats).

Tributyrin oil is a type of lipid called a triglyceride. Other lipase tests use different fat sources such as corn oil, olive oil, peanut oil, egg yolk, and soybean oil.

Lipase allows the organisms that produce it to break down lipids into smaller fragments. Triglycerides are composed of glycerol and three fatty acids. These get broken apart and may be converted into a variety of end-products that could be used by the cell in energy production or other process.

Tributyrin oil forms an opaque suspension in the agar. When an organism produces lipase and breaks down the tributyrin, a clear halo surrounds the areas where the lipase-producing organism has grown.
