<span>The diploid generation of the plant life cycle always produces spores. Diploid is itself a spore producing phase of an organism. These diploid cells produce haploid spores through meiosis. Egg in the ovule is fertilized by sperm that is released by pollen grains. This fertilization gives embryo that gives seed to sprout.</span>

Calix’s karyotype showed that he has a genotype of XXY. Explain how nondisjunction caused Calix to be XXY.
Juli2301 [7.4K]

Answer:

A XY or XY gamete fuses with a normal gamete (X or Y)

Explanation:

Meiotic nondisjunction is the phenomenon whereby chromosomes fail to separate during meiosis I or II. Meiotic nondisjunction leads to the formation of abnormal gametes I.e. gametes with additional or missing chromosomal piece.

The fusion of these abnormal gametes produced by nondisijuction with a normal gamete (X or Y chromosome). This leads to a condition called ANEUPLOIDY, which is a chromosomal disorder. In the case od Calix, XXY is an ANEUPLOIDY state that could have resulted because there was a fusion between a XX gamete and Y gamete or XY and X. The XY or XX gametes are produced as a result of nondisijuction.

Burka [1]

This scientific law is called as Law of conservation of energy.

Sun is the primary source of energy .Energy once produced by the sun is then utilized by the organisms at various tropic levels. The energy is transferred from one organism to another. Energy is neither created nor destroyed. This is called as law of conservation of energy. Plants uses sunlight and make food   and the energy is then transferred to organisms eating it. When the organism dies the energy is released into the environment. This cycle continues and the the law of conservation of energy is maintained.

For the same insolation, order these regions from "highest absorption to lowest."
son4ous [18]
Insolation is the amount of solar energy that is incident on the surface of the earth. For the same insolation, water bodies tend to absorb the most heat as water has a high heat capacity and so do grasslands. Areas such as desserts and glaciers do not absorb high amounts of insolation due to which these areas exhibit extreme, inhabitable environments. The order becomes:
The Atlantic Ocean
A marshy wetland
Nevada desert
Polar ice caps
