Answer:
The five major hormones are: gastrin ( stomach ), secretin ( small intestine ), cholecytokinin (small intestine), gastric inhibitory peptide (small intestine), and motilin (small intestine).
Explanation:
They give it structure mostly. They also surround the organelles.
Answer:
3 (Cells carry out the respiration process)
Explanation:
Cellular respiration is a metabolic (catabolic) process common to all living things as all living things need energy for their life processes.
Respiration is the biochemical process in which the cells of an organism obtain energy by breaking down organic molecules in presence or absence of oxygen (aerobic or anaerobic) resulting in the release of Carbondioxide (CO2), water and Adenosine triphosphate (ATP).
Food molecules (containing stored energy in their chemical bonds) absorbed after digestion are broken down and the energy within their molecules are freed. This freed energy in form of ATP, is used to power the organism's movement and physiological functions.
Note that, ATP is an energy carrying molecule and a usable form of energy by cells. This is so because ATP releases energy quickly. Energy is released from ATP when the end phosphate (Pi) is removed to become ADP (adenosine diphosphate), which is a low energy molecule.
Aerobic cellular respiration consists of Glycolysis, Kreb's cycle and Oxidative phosphorylation. A total of 38 ATP molecules is produced in the cytosol of prokaryotes while a total of 36 ATP molecules is produced in the mitochondria of eukaryotic cells.
<u>Answer:</u>
Common ancestor is the main factor that determines that all terrestrial animals are quadrupedal.
<u>Explanation:</u>
- Phylogeny means the evolution of the organisms or genetically related organism and how they are related.
- The study of phylogeny is called as phylogenetics. Terrestrial means those who live on land.
- Mammals are one who gives birth to their offspring directly. They are generally warm-blooded, breath air.
- Studying each state of the ancestor and also tracing the organism characteristics during evolution.
