Answer:
add a water molecule to break bonds.
Explanation:
Fat digestion occurs in the small intestine where pH is alkaline. Protein digestion starts in the stomach at acidic pH but is completed in small intestine under the conditions of alkaline pH. Both processes use water molecules to break the covalent bonds of the nutrients. Peptidases present in small intestine add water molecules to the peptide bonds that join two amino acids together. This releases the individual amino acids from peptides. Similarly, the enzyme lipase adds water molecules to break the covalent bonds between fatty acids and glycerol of lipid droplets.
Answer:
An advantage to heterospory is endosporic gametophyte.
The endosporic gametophyte do permits for embryonic formation. It prompts it to have a reduced vulnerability to varying form of environments.
The second advantage that heterscopy could offer to plants is ensuring of a well apportioned nutrient filled environment.
The well apportioned nutrient filled environment is formed as a result of the megasporangium been adhered to the sporophytic plant body. This sees to promote a good formation of the embryo.
A further advantage of heterscopy is the aftermath of fertilization.
This integument is hard as it is necessary to preserve the female gametophyte and embryo.
The temperature stability of earth’s atmosphere is mostly due to "b. the rotation of earth about its axis," which is the reason why we have seasons. Water also plays a role.
Answer:
B: gametes that contain only paternal or maternal chromosome
Explanation:
During meiosis, homologous chromosome separates and sister chromatids move to opposite poles as a result of the shortening of the spindle. Since maternal and paternal chromosomes will independent separate during meiosis, this will result in the formation of gametes with either paternal or maternal chromosome and never a mixture of the two.
Paternal chromosomes will assort to give paternal gametes
Maternal chromosomes will assort to give maternal gametes
<em>The correct option is B. The assortment will leads to formation of gametes that contain only paternal or maternal chromosomes</em>
Answer:
The Earth's magnetic field is believed to be generated by electric currents in the conductive iron alloys of its core, created by convection currents due to heat escaping from the core.
