<h2>Phylum Anthophyta</h2>
Explanation:
Phylum Anthophyta is the phylum of flowering plants.
Bryophytes are group of seedless non-vascular plant.They are called the amphibians of plant kingdom because to complete their life cycle, they need both water and land.
Anthophyta are dominant group than the bryophyta because:
- They have a well developed vascular system.
- They have their seeds enclosed within fruits and protective sed coat that keep them viable for a long time.
Answer:
1. The gametophyte generation is haploid.
2. The embryo is diploid.
3. The megaspore is haploid.
4. The sporophyte generation is diploid.
Explanation:
1. Gametophyte- The gametophytic generation is the structure which produces gametes in the plant. Since the gametes are haploid, therefore, the gametophyte us considered the haploid.
2. Embryo- The embryo is formed after the fusion of fertilization when zygote develops, therefore, is considered diploid.
3. Megaspore- the big size spore which is formed from by the meiotic division of the megasporocyte, therefore, is considered haploid.
4. Sporophyte- the sporophyte generation develops from the embryo which is diploid therefore is considered diploid.
Answer:
Answer is A. Vicariance does not require organisms to disperse.
Explanation:
Vicariance occurs when there is a sudden occurrence barrier , such as geographical area barrier that cause the isolation of species of organisms.
Dispersal involves the movement of the organism while vicariance is the change in environment due to sudden occurrence in the area.
In this case, vicariance does not involve movement of organisms while dispersal involves movement of organisms.
Answer: close ended
Explanation:
In a job oriented interview both open and closed ended questions are asked to the job seeker. The open ended interview questions are generally very long answer type questions these questions allows the person to express. These questions are asked to learn about the personality and interests of the job seeker. The closed ended questions are the short questions and they are easy to answer and these can be answered in yes and no. These questions are asked and answered quickly. The chances of mistakes in these questions are more. The chances of misinterpretation of the question is always more in these questions. But these questions allow to get more information about the candidate as compared to the open ended questions as during the open ended question session the job seeker can manipulate the facts but in the case of close ended questions the asking tendency is rapid so no manipulation can occur.
