Well firstly, alleles are different versions of genes. A dominant allele will show it's trait regardless of if the organism only has one copy of the allele (heterozygous). A recessive allele will show the effect only if two copies of the allele are present (homozygous)
Answer:
1. A rock that contains evidence of past animal or plant life is called a <u>fossil</u>.
2. Prehistoric <u>Woolly Mammoth</u> have been discovered in permafrost in Alaska and Siberia.
3. Hardened tree sap can preserve animals in a substance called <u>amber</u>.
4. Fossils can be created by replacement using minerals such as <u>silica</u>, <u>calcite</u>, <u>pyrite</u>.
5. A <u>mold</u> shows the original shape of the plant or animal.
6. A cast represents a <u>solid</u> version of the original plant or animal.
7. Trails, tracks and burrows are examples of <u>trace</u> fossils.
8. Some of the oldest fossils on earth are from ancient <u>worms</u> crawling on the seafloor.
Explanation:
Fossils are known to be the remains of plants and animals which have been preserved and kept in rock. They are usually a shell, skeleton or plant fiber that has been buried. Over time, they turned into rock.
Fossil amber are known to be fossil insects that are preserved in hardened tree sap. These insects and some small animal or plant that are found in these hardened tree sap were trapped in the tree.
Woolly Mammoth is known to be a closest extant relative to the Asian elephant. The appearance and behaviour of woolly mammoth are among the best studied in Siberia and Alaska.
Hello
The type of asexual reproduction done by prokaryotic cells is termed as the binary fission. Binary fission is a reproduction process wherein one cell divides asexually into two cells forming two daughter cells. into In binary fission, the chromosome is being replicated in which the resultant prokaryote is exactly the same copy of the parental prokaryote which means to say that there is no chance for genetic diversity. However, prokaryotes can still share or even exchange genes through the mechanisms of transformation, transduction and conjugation.
