No, after menopause you are not making the hormones necessary to support and sustain a pregnancy.
No, a chain reaction is not possible in a substance that emits no neutrons when it undergoes fission. Neutrons are required to sustain a chain reaction by triggering the fission of other atoms in the substance. Without neutron production, the fission process cannot continue to release energy and sustain the chain reaction.
The flammability of a substance refers to whether or not it will burn. It is a measure of how easily a material will ignite and sustain combustion in the presence of a flame or spark.
flammability. It indicates the substance's ability to ignite and sustain combustion. Highly flammable materials ignite readily and burn rapidly.
Oxygen is necessary for a substance to burn. It reacts with the substance in a chemical reaction known as combustion, releasing heat and light energy. Without oxygen, the substance will not be able to sustain a fire.
The flash point of a substance is the temperature at which it produces enough vapor to ignite briefly when exposed to a flame. The ignition point is the temperature at which the substance will sustain combustion without the need for an external ignition source.
You can be charged for DUI - Driving UNDER THE INFLUENCEof ANYTHING. ANY substance that impairs your driving is sufficient to sustain the charge.
The property that describes how easily a substance catches fire and burns is called flammability. It measures the ability of a material to ignite and sustain combustion when exposed to a heat source.
To "eat out someone's substance" means to consume or deplete someone's resources or wealth, leaving them with little to sustain themselves. It implies taking advantage of someone's generosity or support without giving back in return.
During pregnancy, the placenta secretes hormones that help maintain the uterine lining. These hormones, particularly estrogen and progesterone, support the growth and development of the endometrium to provide a nurturing environment for the growing fetus. If the pregnancy is successful, the placenta continues to produce these hormones throughout gestation to sustain the uterine lining.
If the ignition temperature is lower than the room temperature, the substance will not ignite or burn spontaneously at room temperature. Ignition temperature refers to the minimum temperature required for a substance to ignite and sustain combustion, so if it is lower than the room temperature, the substance will remain stable at that temperature.
