Answer:
Oxytocin
Explanation:
The release of oxytocin is signaled by the fetal brain about 38 weeks after conception. Oxytocin is also called birth hormone as it stimulates uterine contraction.
The uterine contractions stimulate the release of more oxytocin through a positive feedback loop. Oxytocin stimulates contraction of the smooth muscles in the wall of the uterus which in turn finally leads to childbirth.
<span>D. must rely on other means than photosynthesis.
</span>Because sunlight is inadequate at the bottom of the sea, photosynthesis cannot take place. There are no plants and food is scarce; usually decaying matter from dead organisms. Organisms in the bottom of the sea relies on chemicals from hydrothermal vents to create their own food through chemosynthesis.
A cell that has only one set of chromatically would be a haploid.
Answer:
The given statement is false.
It is because the greenhouse effect is a natural process which takes place in the environment by its own.
The greenhouse gases trap the heat energy coming from the sun and the energy which is radiated from the earth and helps in keeping the earth warm.
Natural processes such as volcanic eruptions, cellular respiration, forest fires, transpiration, decomposition et cetera produce greenhouse gases such as carbon dioxide, water vapors, methane et cetera.
The activities of humans increase the effects of the greenhouse effect however, they are not the sole reasons for this natural effect.
Oxygen is produced by photosynthesis. Carbon dioxide is produced by humans or animals inhaling oxygen and relapsing carbon dioxide
