b) a ribosome detaches from the mRNA strand
c) a ribosome reads a start codon
d) mRNA leaves the nucleus for the cytoplasm
Answer:
c) a ribosome reads a start codon
Explanation:
Translation is a process in which a protein is synthesized messenger RNA in (mRNA). The process of translation occurs in ribosomes which mainly synthesize proteins. The ribosomes composed of many mRNA molecules and proteins.The ribosome translate mRNA molecule in three stages namely initiation,elongation and termination. During initiation ribosomal subunits binds to the start of the mRNA sequence.The a molecule of tRNA carries amino acid methionine which to the start codon of the mRNA sequence During elongation ribosomes continuously translate each codon.Amino acid added to a chain by means of a peptide bond.Termination occurs when a ribosome reaches a stop codon,
Answer:
c
Explanation:
a ribosome reads a start codon
a property capable of causing
changes in matter
a carbon-based fuel derived from
living matter that existed in prehistoric
times
the energy of a moving object
2. energy
3. fossil fuel
a material made from plants or
4. kinetic energy

stored energy
5. potential energy
Answer:
fossil fuel- a carbon-based fuel derived from
living matter that existed in prehistoric
times
energy- a property capable of causing
changes in matter
kinetic energy- the energy of a moving object
biomass- a material made from plants or animals
potential energy- stored energy
clearing forests
leaving fields unplanted
careless farming
contour plowing
crop rotation
--
Contour plowing occurs when:
farmers plow fields in horizontal rows
farmers stop plowing fields
farmers plow fields around hills
farmers plow fields around brooks and steams
Answer:
1:
clearing forests
careless farming
2:farmers plow fields around hills
Explanation:
Erosion is caused by the debilitation of the soil, and one of the most common reasons for erosion is clearing forests, also called deforestation, plants and their roots help keep the soil in their place and use the water that runs through the soil helping avoiding erosion, Plowing fields are fields that take advantage of the elevation in the soil and plant in different levels of elevation, helping with this to prevent erosion in the soil.
the cell will swell up and burst
this is due to the constant net movement of water into the cell via osmosis

B.
pepsin
C.
mucus
D.
amylase
Mucus protects the lining of the stomach from acidic gastric juices.
Hydrochloric acid (HCl), lipase, and pepsin come together specifically in gastric juice. Its primary purpose is to render ingested bacteria inactive, preventing infectious pathogens from entering the intestine.
Squamous epithelium, like the skin, is found in the mucosa of the mouth and the esophagus and is thought to serve as a barrier against infection.
Gastric juice makes food particles soluble, starts digestion (especially of proteins), and transforms the contents of the stomach into a semiliquid material termed chyme, laying the groundwork for subsequent small intestine digestion.
Therefore, Mucus protects the lining of the stomach from acidic gastric juices.
