An abiotic factor is a non living thing
Answer:
temperature
Explanation:
I choose temperature because it tells how hot,cold,dry and warm somethings are meanwhile evaporation is when water changes from liquid to gas,so that means water gets hot.
Precipitation is when water released from the cloud to form rain,freezing rain,sleet,snow,or hail.Which means thing get cold.
Air pressure also affect evaporation, which means that water will not be able to come up of the surface of a body of water.So that means the the pressure will be pushing down on the surface of the water.
Answer:
A. The heartbeat can be heard
Explanation:
After the first trimester, during the fourth month, the heartbeat of the fetus becomes loud enough to be heard with the help of a stethoscope placed on the abdomen of the mother.
From fifth to the seventh month of the development, kicks and jabs are felt by the mother as the fetal legs grow and develops. Languo, a wrinkled pink colored skin covers the fetus.
Languo is in turn covered with a white greasy substance called vernix caseosa.
From eighth to ninth months, rotation of the fetus places its head pointing towards the cervix to facilitate childbirth later.
The development of testes takes place in the seventh month while the body hairs become disappeared in the eighth month.
Living organisms obtain many of their requirements by diffusion. They also get rid of many of waste materials in this way. For example, Plants need carbon dioxide for photosynthesis. This diffuses from the air into the leaves through the stomata. It does this because there is a lower concentration of carbon dioxide inside the leaf as the cells are using it up. Outside the leaf in the air, there is a higher concentration. Carbon dioxide molecules therefore diffuse into the leaf down this concentration gradient :)
I hope u understood!
