Answer:
nourish the placenta
Explanation:
The hormone called human placental lactogen (hPL) is a hormone secreted by the placenta, which functions to supply nutrients and oxygen to the growing fetus in the womb.
The human placental lactogen is produced to help in the efficient use of ingested food substances in the production of energy (metabolism). This indirectly helps to nourish the placenta because if the mother efficiently converts food into nutrients, the placenta is also adequately nourished.
1.) working or acting together for mutual benefit

3.) increases the reproductive success
Based on our understanding, we can confirm that the structures that comprise the outer ear include the tragus, helix, and the lobule.
<h3>What is the outer ear?</h3>
Contrary to that of the inner ear, the outer ear includes the parts of this organ that do not actually influence our ability to hear. These parts include the components of the ear that we are able to see on an everyday basis, separated into three distinct parts named the tragus, helix, and lobule.
Therefore, we can confirm that the structures that comprise the outer ear include the tragus, helix, and the lobule.

Answer:
Water added
Explanation:
The above option is the best that represents the missing step.
This process is known simply to be cellular respiration. It is also the reverse of photosynthesis.
In this process, food is broken down in a chemical reaction with oxygen. As this process occurs, carbon dioxide and water are the products. So, in this process, water is added as the product of the breaking down process.
Respiration is seen to be almost the exact opposite of photosynthesis. These two reactions help to maintain biological energy balance on earth.
The result is its increased altitude
