Answer:
A terrarium with a plant and a snail
Explanation:
This is because snail uses oxygen for cellular respiration and releases carbondioxide as by product.
Where as plants uses carbondioxide exhaled for photosynthesis in the presence of light energy and chlorophyll with water to produce glucose and oxygen. Therefore cycle if oxygen and carbondioxide gases is continuous.
Laurentia<span> (</span>North American Craton<span>) is a large continental </span>craton<span> that forms the ancient geological core of the </span>North American<span> continent. Many times in its past, Laurentia has been a separate </span>continent<span> as it is now in the form of North America, although originally it also included the cratonic areas of </span>Greenland<span> and also the northwestern part of </span>Scotland, known as theHebridean Terrane<span>. During other times in its past, Laurentia has been part of larger continents and </span>supercontinents<span> and itself consists of many smaller </span>terranes<span> assembled on a network of Early </span>Proterozoic orogenic<span> belts. Small </span>microcontinents<span> and oceanic islands collided with and sutured onto the ever-growing Laurentia, and together formed the stable </span>Precambriancraton seen today.
Natural selection<span> acts upon two major sources of genetic variation: </span>mutations<span> and</span>recombination<span> of </span>genes<span> through sexual </span>reproduction<span>. Most </span>mutations<span> do not affect the reproductive fitness of individuals -- some may be beneficial, some may be harmful, and </span>many<span> may be neutral. </span>Mutation rates<span> per gene are generally low</span>
Correct options A) None
Autosomal dominate refers to alleles harbored by any chromosome other than the sexual pair that show complete dominance over the recessive ones.
The dwarf male father with normal height is homozygous recessive for achondroplasia. The male of heterozygous for the character because this is autosomal dominant. He is also normal vision reason he is X-NY.
The women is color blind and normal height. The cross is X-NYAa x XnX naa. The father will produced gametes x-NA,X-Na , YA and Ya and the mother only gamete X-na. So the son of this type of couple is X-nYAa which can be color blind and dwarf and normal height.
