Read the passage carefully and answer the questions based on the passage:
Pollen pistil interaction involves all events from the landing of pollen grains on the stigma until the pollen tube enters the embryo sac (when the pollen is compatible). When a pollen tube grows through the style and enters into the ovules, it finally discharges two male gametes in one of the synergids. Syngamy and triple fusion are two fusion events occur in angiosperms. Thus, angiosperms exhibit double fertilization. The products of these fusions are the diploid zygote and triploid primary endosperm nucleus. Zygote develops into embryo and primary endosperm cell forms the endosperm tissue. The developing embryo passes through different stages before maturation.
With reference to reproduction in flowering plants, which one of the following is incorrect?

Which type of population interaction is exhibited by 'mycorrhizae'?

About ______ the first cellular forms of life appeared on earth.

Read the following paragraph carefully and answer the given questions.
In the year 1963 the two enzymes responsible for restricting the growth of bacteriophage in E. coli were isolated. The first restriction endonuclease - Hind II, whose functioning depended on a specific DNA nucleotide sequence was characterized five years later. It was found that Hind II always cut DNA molecules at a particular point by recognizing a specific sequence of six base pairs. This specific base sequence is known as the recognition sequence for Hind II. Besides Hind II, today we know more than 900 restriction enzymes that have been isolated from over 230 strains of bacteria, each of which recognize different recognition sequences.
Hind II is a restriction endonuclease because

A parallel plate capacitor having plate area 200 \( cm^2 \) and separation 2.0 mm holds a charge of \( 0.06\mu C \) on applying a potential difference of 60 V. The dielectric constant of the material filled in between the plates is.
Given permittivity of the vaccum \(\epsilon_0=8.85 \times 10^{-12} F / m \))

Minimum percentage of global biodiversity in major invertebrate and plant taxa, is seen in:

Consider the following data:

Year (x)	2004	2005	2006	2007	2008	2009	2010
Profit (₹) (y)	114	130	126	144	138	156	164

The equation of straight line trend by using least square method is, y =138.86 + 7.64 (x - 2007), then the trend values for the year 2004 is
