Chemical Weathering<span> results from chemical reactions between minerals in rocks and external agents like air or water. Oxygen oxidizes minerals to alteration products whereas water can convert minerals to clays or dissolve minerals completely. is that what your asking?</span>
Answer;
3. the two organisms belong to the same kingdom
Explanation;
-The classification of living things includes 7 levels, from the highest to lowest rank: kingdom, phylum, classes, order, families, genus, and species . The most basic classification of living things is kingdoms.
-The broadest classifications are by domain and kingdom; the most specific classification is by genus and species.
Therefore; if two organisms are in the same phylum, then it means they both belong to the same kingdom, because kingdom is the rank of classification higher than phylum.
Answer:
The probability is ½
Explanation:
Since the dimple trait is simple dominance, it therefore can be inherited in both the homozygous (DD) and heterozygous form (Dd). For non dimples we have (dd).
Thus, for a dimpled man whose mother has no dimples, it can be concluded that he is an heterozygote. (For him to be dimpled with a non dimpled mom, his dad has to be either an homozygous/heterozygous dimpled man. Since his mom is non dimpled (dd), therefore he can only be an heterozygous)
Therefore, a cross between a dimpled man (Dd) and a non dimpled woman will give.
Dd x dd
Dd dd
