Answer:
The correct answer is D)
Cycle energy and matter to support the biosphere as a closed energy system
Explanation:
The earth as we know it is a closed energy system that is, matter cannot be introduced or removed from it. Sometimes, rare meterites enter into the system with minimal or no disruption.
Also, energy can enter and leave. The energy mostly referenced here is the sun.
Within the earths system, the lithosphere, hydrosphere, and biosphere materials and energy go through a cycle which helps to support life.
For example, water when heated up by the sun rises as vapour from the earth and oceans into the atmosphere where it cools and condenses. When it cools and condenses, it
, in the form of rain, comes down on the earth and oceans. As rain falls down to the earth and runs off the rocks, rocks are broken down into smaller fragments and soils. The hydrosphere comprises of all water bodies on earth. Besides the vapours which are evaporated from the same into the atmosphere, when volcanoes erupt they also send vapourised water into the atmosphere.
So because the earth is a closed system, a change in one sphere effects a change in others. An example is a change in the water cycle.

Dominant means more. 100% is all so like all black. 50 is half-half which is wrong because its supposed to be more. 25% is wrong because its "more" so it has to be 75%
Hope this helps :D Please mark brainliest if correct D:
Answer:
There are 22 numbered pairs of chromosomes called autosomes. The 23rd pair of chromosomes are the sex chromosomes. They determine an individual's sex. Females have two X chromosomes, and males have an X and a Y chromosome.
This is how you know if a karyotype is male or female?
Gametes are mature haploid cells, or sex cells. When gametes unite with others from the opposite sex in the form of fertilization they create a zygote which then forms an embryo etc. At the end of meiosis the gametes only have <u>half</u> the chromosomes of the organism (only one copy of DNA)
Answer: C. It allows gametes to have half the original number of chromosomes of the organism.
Answer:
there are 5 breeding pairs
