Answer:false
Explanation:the cell wall is a rigid , protective wall that surrounds the plasma membrane.
The rigidity of the cell wall is due primarily to the presence of cellulose and other materials such as lignin and pectin.
Cellulose is a polysaccharide and the plant cell wall is made up of several molecules of it.
Lignin is a rigid and impermeable material and deposited on the cellulose as an extra reinforcement on the cell wall.
Pectin are found in the middle lamellae and helps to cement the adjacent cell walls.
There is also hemicellulose which binds to the cellulose mifilaments.
The cell wall may also possesses plasmodermata,which are pores through which water and nutrients pass adjacent cells.
This rigid covering of the cell prevents it from expanding and shrinking due to water movement in and out of the cells
Answer:
A similarity between alcohol fermentation and aerobic respiration is that both started with glycolysis.
Explanation:
Alcohol fermentation is anaerobic process which involve the conversion of glucose into carbon dioxide and alcohol in the presence of yeast.
The first step is glycolysis which is same in both alcohol fermentation and aerobic respiration
Both produces the ATP. The number of ATP produced by alcohol fermentation are 2 while aerobic respiration produces 38 ATP.
Aerobic respiration
It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.
Glucose + oxygen → carbon dioxide + water + 38ATP
Is it recessive? Not sure.
It’s nucleotides, I hope this helps and it’s not too late to answer :)
Herbivore
Predation
Explanation:
The interaction between the sheep and the grasses/clovers they eat is a herbivory.
The bears eating the sheep is as predation interaction.
- Herbivores are animals that feeds on plants. They derive their nourishment directly from plant materials. They simply feed on herbs i.e plants.
- Interaction between a bear and the sheep is a predation. In this interaction an organism kills and consumers another called the prey. The consuming organism is the predator and the consumed is the prey.
- Most predators are called carnivores which are flesh eaters. The predator is the bear and the prey is the sheep.
