Answer:

A cell wall is a  structural layer covering some types of cells. It is the external covering of plant cell.

It is tough, rigid or sometimes flexible in nature. It acts as the structural support and also provides protection to the plant by performing the filtering mechanism. Cell wall is made of different composition , like plants have cell wall made up of cellulose.

Cell membrane or the cytoplasmic membrane is a biological membrane that is made up of lipid bi layer with embedded proteins. It is selectively permeable.

The correct answer is:

a cell wall is only included on the plant cell

the cell membrane is included in both plant and animal cells

Explanation:

The cell wall is the outer most integument of the cell. The cell wall covers the cell membrane. The cell membrane is also known as the plasma membrane or plasmalemma. There is no another name for the cell wall. The cell membrane is being in almost all types of cells.

The purpose of the cell membrane is the equivalent as that of the skin. It leaves the elements inside the cell from the outside. The cell membrane provides assistance to the cytoskeleton of the cell, gives shape to the cell, and helps in the formation of tissues by adding the matrix located in the extracellular. It allows the passage of a certain substance.A cell membrane is incorporated by the cell wall which forms the outer most integument.

Brief description of a sea otter​

<h3>An intelligent, water-agile mammal with a main diet of sea urchins.</h3>

Sea otters tend to inhabit the shores of the pacific (sometimes rivers, ponds, or lakes), a favorite habitat is the kelp forests on the coast of California. Mother otters even tie their babies (and sometimes themselves) in kelp leaves, keeping them near and preventing floating away when diving for food. This is a clear sign of intelligence, and they classify as mammals. Otters stay in groups led by a dominant male, but sometimes females will leave with their babies, or males will depart in search of their own group to manage.

Producers, consumers, and decomposers play important roles in the environment. Are there any organisms that would not fall into
choli [55]

Answer:

No, there are no organisms that will not fall into these categories

Explanation:

Living organisms interact with one another in their natural environment in order to ensure that energy needed for their metabolic activities is obtained. To do this, each organism plays different or specific roles. The roles that every organism must fall into are as follows:

- Producers are groups of organisms that have the ability to synthesize their own food using light (photosynthesis) or chemicals (chemosynthesis). Examples are green plants, algae, some bacteria etc.

- Consumers- These are organisms that lack the ability to synthesize their own food and hence depend on other organisms for their energy source. Consumers can either be herbivores (eat plants) or carnivores (eat flesh) etc. Examples are all animals etc.

- Decomposers- These are organism that have the ability to breakdown dead organisms into organic matter, thereby, adding nutrients back to the soil. Examples are fungi, bacteria, earthworm etc.

Based on this explanation above, no organism will not fall into any of these three categories. Some can even occupy two roles.

Why is Earth considered a system? What are the main parts that make up the Earth system?
Rashid [163]

Answer:

The earth is a vast, complex system powered by two sources of energy: an internal source (the decay of radioactive elements in the geosphere, which generates geothermal heat) and an external source (the solar radiation received from the Sun); the vast majority of the energy in the earth system comes from the Sun.

Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air).

Answer:

The answer to your question is  3'- TACAAGC -5'

Explanation:

Original strand              5' - ATGTTCG - 3'

Complementary strand = ?

Just remember Nitrogenous bases

Adenine     attach to Thymine                 Thymine attach to  Adenine

Guanine     attach to Cytosine                 Cytosine attach to Guanine

Then, the complementary sequence will be

                                   3'- TACAAGC -5'
