How is mass wasting different from other forms of erosion?
Romashka-Z-Leto [24]

Answer:

A

Explanation:

Examples of mass wasting are slides, falls, creeps, and flows.  Mass wasting processes are easily observable because they happen fast and suddenly and the changes are vividly evident in very short bit of time.   However, other methods of erosion such as mechanical and physical weathering occur very slowly and it would take many years for the changes associated wth their proceses to be vivid to the naked eye.

Instructions: 1 Using the DNA sequence, make a complementary RNA strand from both the human and the cow. Write the RNA directly
Ksenya-84 [330]

Answer:

Please find the complete table attached as an image

Explanation:

This task is describing the processes of transcription and translation, which are the two processes involved in gene expression. The DNA of a human and cow is given in the table of the attached image and we're asked to transcribe into a complementary RNA, and subsequently translate into an amino acid using the CODON table (genetic code).

- Transcription is the process whereby DNA is used as a template for the synthesis of RNA based on complementary base pairing i.e. A-U, G-C, T-A etc.

- Translation is the process whereby RNA transcript is used to synthesize an amino acid sequence. The mRNA is read in a group of three nucleotides called CODON, where each of this codon specifies an amino acid.

The table has been completed and attached below. Note that in the amino acids row;

GLY means Glycine

ILE means Isoleucine

VAL means Valine

GLN means Glutamine

CYS means Cysteine

THR means Threonine

SER means Serine

PHE means Phenylalanine

ALA means Alanine

LEU means Leucine
