Answer:
1.Plasma membrane
The plasma membrane surrounds the cell to create a barrier between the cytosol and the extracellular matrix. Plasma membranes also enclose lumens of some cellular organelles.
2.Endoplasmic reticulum
The endoplasmic reticulum (ER) is a large network of membranes responsible for the production of proteins, metabolism and transportation of lipids, and detoxification of poisons. There are two types of endoplasmic reticulum with separate functions: smooth endoplasmic reticulum and rough endoplasmic reticulum. The presence or absence of ribosomes in the ER’s plasma membrane determines whether it is classified as smooth or rough ER.
3.Golgi apparatus
The Golgi apparatus appears as a series of flattened, membranous sacs, or cisternae, that resemble a stack of pancakes just off the rough endoplasmic reticulum. It receives vesicles containing proteins recently produced by the rER. The Golgi apparatus can be compared to a warehouse or post office for newly formed proteins. Here the proteins are further modified, packaged, and sent off to their final destinations in the cell or body.
The correct answer is option D, Temporal isolation
Temporal isolation is the mechanism which prevents the mating of closely related species living in the same ecosystem. Basically the reproductive barriers prevent these species from interbreeding. Temporal isolation is a prezygotic barrier that causes “time isolation” between the breeding period of two closely related species. The difference in time could be “difference in time of day”, “ difference in season of mating”, “difference in months” and in some cases “ difference in years”.
Answer: Im not good at plants but here:
Explanation:
1. Grow the plant (Seed, Water, Wait for it to grow)
2. Feed it with water and keep it in dirt / soil in the sunlight.
Thats all the advice I have!
Answer: The correct answer is It produces gametes that are needed for sexual reproduction.
Explanation-
Meiosis is a type of cell division, which is a characteristic feature of sexually reproducing organisms. It produces reproductive cells called gametes, which possess half number of chromosomes as compared to their parental cells ( which are diploid). Gametes from each parent fuse to form a diploid zygote that develops into an individual.
Thus, it summarizes the importance of meiosis to reproduction.
