Answer: Blood to kidney excretory tubes,
- Air tubes to blood
- Blood to air tubes.
The body contains several internal exchange systems. In the kidney, metabolic wastes move from BLOOD to KIDNEY EXCRETORY TUBES. In the lung, oxygen moves from AIR TUBES to BLOOD, while carbon dioxide moves from BLOOD to AIR TUBES.
Explanation: In the kidney, metabolic wastes move from the blood to the kidney excretory tubes via the affarent arteriole into the glomerulus of the bowman's capsule from where there will be ultrafiltration of the wastes from the blood will take place followed by selective reabsorption and tubular secretion inorder for urine to be formed.
In the lungs,oxygen moves from the air tubes which are the bronchial tubes then to the alveoli where gaseous exchange takes place then the oxygen moves to the blood. While carbondioxide moves from the blood to the air tubes from where there is exchange of gases then the carbondioxide is exhaled/expired from the lungs.
Answer:
B. Little to no change in temperatures between seasons.
Assuming planet A is the earth, the earth is very slightly rotated on its axis toward the sun and Jupiter, so there would not be a dramatic change if we tilted the earth 5 degrees.
The structures that would likely be examples of divergent evolution are the homologous structures. These are structures which share a similar structure and appear in different organisms and yet may vary in function. For example; Mammalian forelimbs are said to be homologous because they are all derived from a vertebrate forelimb.
Answer:
Exothermic gives off hear. Endothermic absorbs heat.
Explanation:
Answer:
- Mutation
- If organisms choose a mate for a specific reason
- People moving into or out of an area
- If the population shrinks
Explanation:
These factors are the "forces of evolution." There are four such forces: mutation, gene flow, genetic drift, and natural selection.
