<span>The answer is the option C. hypothesis. If the option A, confuses you, think that an experiment is not per se an explanation, it is just a way to run trials to determine something. Hypothesis are statements that establish a possible relations between facts but that are not proved. Then you can design an experiment to test the validity or not of the hypothesis. You should not make hypothesis that cannot be testable. </span>
Answer:
d
Explanation:
<em>Crossing over shuffles alleles on non-sister chromatids of homologous chromosomes.</em>
At the prophase I stage of meiosis, homologous chromosomes synapsed to form a four-chromatid structure known as tetrad. Exchange of chromosomal segments between non-sister chromatids of the tetrad then takes place, a process that results in the reshuffling of genes or alleles on the non-sister chromatids.
Hence, none of the answers is correct.
Correct option: d
When the ground position of a front moves so that warm air occupies territory that was previously held by cold air, <u>It is knows a </u><u>warm front.</u>
<u></u>
- The area where a warm air mass is replacing a cold air mass is known as a warm front.
- The air behind a warm front is warmer and more humid than the air in front of it. Warm fronts typically migrate from the southwest to the northeast.
- A warm front is a density discontinuity that is usually seen on the margin of an isotherm gradient that faces the equator and is situated at the leading edge of a homogenous warm air mass.
- Since warm air is thicker and more difficult to remove from the surface of the Earth than cold air, warm fronts move more slowly than the cold fronts that typically follow them.

5. The phenotypic ratio is 9:3:3:1 where 9 combinations will produce offspring with both dominant phenotypes (dimples and brown hair), 3 will produce offspring with one dominant phenotype and one receive phenotype (dimples, blonde hair), 3 will produce offspring with one receive phenotype and one dominant phenotype (no dimples, brown hair), and one will produce offspring with both recessive phenotypes (no dimples, blonde hair)
Well there different because a habitat is the environment in which the animals live and a niche is the role animals play in that environment. So they are different but they work hand & hand in creating a good environment.
