Which characteristics do cell membranes and cell walls have in common?

Answers

Answer 1
Answer: Both protexts the organisms' organelles which are inside the cell.
Animal Cell: Cell Membrane
Plant Cell: Cell Wall
Cellwall is present only in plants, it is not found in all organisms.Compared to the cell membrane, a cell wall is thick and has a rigidstructure. You can see it in a light microscope, because it is visible.It serves as the protective cover that surrounds the plasma membrane in aplant cell. Cell membrane is composed of lipids. Cell walls can be madeup of cellulose or peptidoglycan or chitin.

Organisms are classified as fungi if they

Answers

Organisms are classified as fungi if they have chitin in their cell walls.

Fungi are eukaryotic organisms (such as yeasts and molds) that usually have chitins in their cell walls but no chlorophyll or plastids. Fungi may be unicellular or multicellular. Fungi do not photosynthesize but they are heterotrophs like animals. They get their food by absorbing dissolved substances and they usually reproduce by means of spores.


What is the function of sucrase in the breakdown of table sugar\

Answers

A starch molecule is formed when many disaccharide molecules are combined.  Starch is often produced in plants as a means of storing energy. The two other molecules formed when multiple disaccharide molecules are combined are cellulose and glycogen. The cell walls in plants are made up of cellulose. Glycogen is a carbohydrate energy source. 
A disaccharide molecule is formed when two monosaccharide molecules are joined together. Maltose, sucrose and lactose are the most important disaccharides. A monosaccharide molecule is a simple sugar, for example, glucose. 

How do both a bird and a reptile reproduce?a. They both lay eggs in the water.
b. They both lay amniotic eggs.
c. They both have live babies.

Answers

The answer is b. They both lay amniotic eggs.

Both birds and reptiles belong to a clade of vertebrates, Amniotes, which lay amniotic eggs. Mammals also belong to Amniotes. Amniotic eggs can remain within the mother after fertilization or can be laid on land. On the other side, anamniotic eggs are usually laid in the water.

Explain how the wind may be involved in the formation of sandstone arches.

Answers

Answer

Wind may be involved in the formation of sandstone arches by facilitating erosion which wore away exposed sections of rocks and enlarges the cracks on the surface forming marrow sandstone fins.

Explanation

Sandstone arches can be formed when a large piece of sandstone flaked off as a result of high winds. In addition to that, alternative frost and thawing can result into crumbling of porous sandstone which will in the long run cut through some fins. These resulting holes enlarge to form arches with effects of weathering and rock fall caused by wind.



Answer:

Sandstone arches are formed when large pieces of sandstone flaked off, withered or cut down due to the affect of high current winds. The sandstones which are exposed to such high speed winds forms bridge or arch creating a cavity in the sandstone.

Three species of North American warblers are found to feed in different parts of the same spruce tree. This particular behavior of warblers displays which ecological characteristic?

Answers

In this particular behavior, the three species of North American warblers cannot share the same niche in the same habitat. It is called "Gause's Competitive Exclusion Principle." It means the competitors with equal bearing cannot exist. There will always be the dominant one in a competition.
