Answer:
11km
Explanation:
The total distance travelled is the sum of the distance as follows:
- from home to friend's house
- from friend's house back home
- from home to the mall
According to this question;
* I walked from my house to my friend's place and covered 0.5km
* I walked back from my friend's house home in the same 0.5km
* I drove to the mall from my house and covered a distance of 10km
Hence, the total distance covered is 0.5 + 0.5 + 10
= 11km
What I learned during this activity is how to properly set up a slide for viewing. I learned how to focus a microscope to make the image from the ocular more clear. How to view the different parts of a cell using dye to brighten up the key parts of the cell such as the cells Membrane, Cytoplasm, Nucleus, Ribosomes, Lysosomes, Mitochondria.
Mutations are random and rare changes in the DNA sequence that can both add or delete genes. (therefore, all of the answers listed above apply)
In genetics, the term mutation represents any change in the DNA sequence of an organism. Mutations can be limited to a change in just a single nucleotide ( Single Nucleotide Polymorphisms) or it can include deletions, insertions or translocation of a longer DNA sequence, sometimes even whole genes. Mutations are rare and random events, but there are some places in the genome that are more prone to genetic mutations, called ''hot spots''.
