A color-blind (X-linked recessive) human with Klinefelter syndrome has parents both of whom have normal color vision. 4a. From w
sineoko [7]

The extra X chromosome is received from mother.

<h3><u>Explanation</u>:</h3>

Klinefelter's syndrome is the condition of chromosomal aberration where the person has an extra X chromosome. This means the genotype of the person is 44+XXY and the total chromosome number is 47. This condition is achieved due to inappropriate meiotic division and one of the sperm or ovum has the an extra X chromosome.

Here both the parents are normal in terms of colour vision. So the father cannot have the gene of colour blindness because if it was present, then father would have been colour blind because he has only one X chromosome per cell. So its present in mother who is heterozygous in terms of colour blind gene. So the extra X chromosome also came from her which made the presence of two defective X chromosomes in the offspring and made it colour blind.

1. This scene is in British Columbia's Mount Robson Provincial Park.
solniwko [45]

There are four environments on Earth that are called spheres: hydrosphere, lithosphere, atmosphere, and biosphere.

<h3>Features associated with each of Earth's four spheres.</h3>

<h3>Hydrosphere </h3>

It is the set of all the water on the planet, including those that form clouds.

<h3>Lithosphere</h3>

The continuous part of our planet, made up of rocks and soil. The most superficial part is called the earth's crust.

<h3>Atmosphere</h3>

It is the gaseous sphere that surrounds our planet, composed mainly of gas oxygen and gas.

<h3>Biosphere </h3>

It is the part of our planet that can support life

<h3>Internal processes</h3>

The atmosphere and hydrosphere are the main regulators of the planet's climate. Without both, the temperature changes would be very sudden: at night it would drop to minus 150°C and during the day above 100°C, making life on Earth difficult.

With this information, we can conclude that the spheres of the earth, support life, and make the planet earth unique.
