Answer:

The correct answer is option A. diploid zygote and a triploid endosperm.

Explanation:

Double fertilization is a type of fertilization that is a complex mechanism takes place in angiosperms in which a female gametophyte fuse with two male gametes. In this process, pollen grains pollinate the female reproductive structure which is the stigma of the carpel.

The double fertilization process includes two male gametes, one of the gametes fuses with the egg cell and fertilizes it which forms the zygote whereas other gamete fuses with the nuclei cell which is two in number to form the endosperm.

Thus, the correct answer is option A. diploid zygote and a triploid endosperm.

What do you mean by sex​
ValentinkaMS [17]
In general terms, “sex” refers to the biological differences between males and females, such as the genitalia and genetic differences. “Gender” is more difficult to define, but it can refer to the role of a male or female in society, known as a gender role, or an individual's concept of themselves, or gender identity.

The table below shows the dimensions of two colored cubes.
Lelechka [254]

Answer: The correct answer is black because the product of its side and mass is lower.

Explanation: Density of a substance is defined as the mount of matter that can be stored in a given volume.

Mathematically,

Density=\frac{Mass}{volume}

As, density is inversely proportional to the volume of the substance.

The substance will be more denser if it has less volume and it will be less denser if the volume is more.

We are given two cubes having different sides.

Volume of the cube is calculated by using the formula:

V=a^3

where, a = side of the cube.

Black: The side of this cube is 2 and volume will be = 2^3=8cm^3

Yellow: The side of this cube is 3 and volume will be = 3^3=27cm^3


As, the volume of black cube is less. So, this cube will be more denser.

Density of black cube: \frac{48}{8}=6g/cm^3

Density of Yellow Cube: \frac{135}{27}=5g/cm^3

Hence, black cube will be more denser  because the product of its side and mass is lower.
