Consider the following statements regarding the changes which usually occur in the ovule during the development of seed and choose the correct answer:<br>1. The zygote develops into a fruit<br>2. The seeds having copious amounts of endosperm tissue are called exalbuminous<br>3. The exalbuminous seeds usually store reserve food materials in cotyledons<br>4. The inner integument, if persists, forms the

Correct Answer: Only 3 is true

Consider the following statements and choose the correct answer:
1. The integuments of the ovule become dry and firm, the seed coat
2. Insoluble food is formed in the ovule as a result of dehydration
3. In endospermic seeds the insoluble food is stored in cotyledons
4. The ovary wall forms the fruit wall which may be hard or fleshy

Select the four statements about Plasmodium that are true. A)Inside an infected mosquito, haploid gametes fuse, forming a diploid zygote that develops into an oocyst B) Plasmodium cells infect two specific types of cells in humans. C) Inside an infected mosquito, haploid gametes fuse, forming a haploid zygote that develops into an oocyst. D) When a mosquito bites a human with malaria, diploid Plasmodium cells enter the mosquito. E) Plasmodium cells are transferred to humans through mosquito saliva. F) The life cycle of Plasmodium involves only haploid forms. G) The complete life cycle of Plasmodium requires two hosts.

Consider the following statements regarding Xenia and choose the correct answer:
1. If a white variety (yy) is pollinated with pollen from a yellow variety (YY), one of the male gametes (Y) will unite with the egg (y) to produce a hybrid embryo (Yy) which will act as a heterozygote for yellow endosperm in the next generation
2. The second male gamete (Y) will unite with the two polar nuclei (y, y) and produces the primary endosperm nucleus (Yyy) which is triploid
3. If a yellow endosperm variety (YY) is crossed with pollen from a white grained variety, the grains produced are white like the pollen parent

Sue planted 4 times as many apple seeds as she planted orange seeds. 15% of the apple seeds grew into trees, and 10% of the orange seeds grew into trees. If a total of 420 apple trees and orange trees grew from the seeds, how many orange seeds did Sue plant?

Consider the following statements regarding the importance of imbibition to the plants and choose the correct answer:
1. Imbibition causes swelling of seeds and results in the breaking of testa
2. The water moves into ovules which are ripening into seeds by the process of imbibition
3. Imbibition pressure generated during germination of seeds and spores is so enormous that it can break asphalt road and concrete pavements

Consider the following statements and choose the correct answer:
1. For the development of viable seeds the double fertilization is very necessary
2. The net result of double fertilization is the formation of endosperm from the triploid nucleus
3. In Angiosperms very free nuclear divisions take place as in Gymnosperms
4. The endosperm nucleus has both maternal and paternal characters showing physiological importance like hybrid vigour

Two involute gears are designed to mesh for a given centre distance and a given angular velocity ratio (other than 1). During assembly, the centre distance has increased slightly. Then which of the following changes occur? (i) Velocity ratio changes (ii) Pressure angle changes (iii) Pitch circle diameter changes (iv) Working depth changes (v) Base circle radius changes Select the correct answer using the code given below.

Consider the following statements regarding sporogenesis and choose the correct answer:
1. Gametes ape always unicellular and microscopic in size
2. The union of similar gametes is called fertilization
3. The zygote formed as a result of fertilization is called zygospore
4. The seed on germination gives rise to a new plant

Seven people A, B, C, D, E, F and G live on separate floors of a 7-floor building. Ground floor is numbered 1, first floor is numbered. 2 and so on until the topmost floor is numbered 7. Each one of these having a different cars-Cadillac, Ambassador, Fiat, Maruti, Mercedes, Bedford and Fargo but not necessarily in the same order. Only three people live above the floor on which A lives. Only one person lives between A and the one having a car Cadillac. F lives immediately below the one having a car Bedford. The one having a car Bedford lives on an even-numbered floor. Only three people live between the ones having a car Cadillac and Maruti. E lives immediately above C. E is not having a car Maruti. Only two people live between B and the one having a car Fargo. The one having a car Fargo lives below the floor on which B lives. The one having a car Fiat does not live immediately above D or immediately below B. D does not live immediately above or immediately below A. G does not have a car Ambassador. Question : How many people live between the floors on which D and the one having a car Bedford ?

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create anapplication. The application uses the ADO.NET Entity Framework to model entities. Theapplication allows users to make changes to entities while disconnected from the central data store. You need to ensure that when the user connects to the central data store and retrieves new data, the application meets the following requirements:
  • Changes made to the local data store in disconnected mode are preserved.
  • Entities that have already been loaded into the local data store, but have not been modified by the user, are updated with the latest data.
