Based on what you've learned, briefly explain the evolutionary significance of the fact that parents pass on their chromosomes to their children. What happens when there is an error in the mechanisms by which chromosomes are passed down? What are some genetic disorders that can arise from mutations that are either inherited or acquired? A sample answer might look like this: Parents pass on their chromosomes to their children because the DNA, packaged in the chromosomes, provides the instructions for all cells in the body to function. If there is an error in the mechanisms by which chromosomes are passed down, the chromosomes may not be passed down properly. This could lead to genetic disorders. There are many examples of genetic disorders that range from very minor to very severe. A frameshift mutation causes Tay-Sachs disease, an autosomal recessive disorder that is typically fatal. Frameshift mutations, in which the DNA or RNA sequence's reading frame is shifted by the addition or deletion of nucleotides, can have catastrophic consequences.

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.  

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
