Answer:
gravel, rocks with cracks, loosely packed soil
Explanation:
all tree has room for water to flow through
• Homologous structures: Both Ostriches have wings similar in form to those of their ancestors, but that do not allow the birds to fly.
Homologous structures are those that have structural similarities but are different in function. For example, if we look at the anatomical structure of a bird’s wing, it is very similar in structure with a human arm. However, over the course of time they have evolved to perform different functions.
• Vestigial structures: The inner ear bones of mammals have evolved from bones that form the jaws of reptiles.
Vestigiality refers to the process in which some structure lose their function over the course of evolution in some specie but they are functionally normal in other species. Such a structure is the inner ear bones of mammals which donot perform an important function in mammals but do perform in reptiles.
• DNA sequence data: Both Genes involved in RNA replication are conserved among bacteria and animals, suggesting a common evolutionary origin.
The sequencing of genetic data is an excellent method of finding the evolutionary histories and relatedness of different organisms. This field of sciences is called phylogenetics and the mentioned example is the result of phylogenetics.
• Analogous structures: The jointed legs of insects and vertebrates arose independently, indicating a different evolutionary origin.
Analogous structures are those that have similar function but they look very different in structure or anatomy. This is because they have been evolved from different ancestors and perform different functions. One example of these structures is mentioned, The jointed legs of insects and vertebrates that look different bur perform same function.
Answer:
Clay is not mined in Minnesota.
Explanation:
- Minerals that are found in Minnesota are broadly categorized into two types- metallic minerals and industrial minerals.
- Metallic minerals divided into ferrous mineral which contain iron and non ferrous minerals donot contain iron but it contain other metals like copper.
- Metallic minerals contain iron ore,where as non ferrous minerals contain manganese,copper,nickel,platinum,titanium etc.
- Industrial minerals include sand,gravel,peat,landscape stone,silica sand,limestone, china clay etc.
- Some times,different bedrock are mined like quartzite, granite, gabbro, gnesis etc.
Answer;
cells are very different but have similar properties
Explanation;
-Even though there are many different types of cells, they all share similar characteristics. All cells have a cell membrane, organelles organelles, cytoplasm, and DNA. All cells are surrounded by a cell membrane, all cells contain organelles, all cells contain cytoplasm and all cells contain DNA.
-Cells may differ in their number such that some organisms are made of only a single cell while other organisms are made of billions of cells
