Answer: the carbon-12 atom

Explanation: The International Union of Pure and Applied Chemistry (IUPAC), defined 1 atomic mass unit as 1/12 the mass of carbon-12. That is to say carbon-12 has a mass of 12 amu. The carbon-12 isotope is abundant in nature. Carbon is usually found as a compound with other elements.

After many years of debating, chemists and physicists agreed to the use of carbon-12 to be the best unit for the measurement for atomic masses.

Previous standards that was used were hydrogen and oxygen but scientists found it difficult using these elements as standards due to the distribution of their isotopes.

Water vapor in the air condenses into liquid droplets when the water reaches ____. A. A warm front B. Its critical elevation C.
Vsevolod [243]

C

Dew point is the temperature of an air mass in which the water vapor (humidity) starts to condense into droplets due to saturation. This is when dew begins to form.

Explanation:

The higher the temperature the higher the water vapor the air mass can hold. This is because the intermolecular spaces between the air molecules become larger with increased temperature hence can accommodate more water vapor molecules in between the air molecules. As the air mass cools the intermolecular spaces become shorter and the relative humidity of the air mass increases. At temperatures where the air mass can't accommodate its humidity, this is called the dew point, and the water vapor begins to condense into droplets (dew).

Which of the following hazards oan severely harm a worker's lungs?
san4es73 [151]

Answer:

I think that this might be your answer :) I tried hope this helps !

Explanation:

A) Heat exposure Because In terms of weather Heat:  Inhaling hot air, induces airway constriction making it difficult to breathe.

Also Of course, it's known that smoke from fire can have a terrible effect on your lungs. It can restrict oxygen flow, which can and most likely be deadly. So the exposure to the heat will distract them cause they cant breath while they work .

What is the name of worlds largest seed?​
kondor19780726 [428]

Answer:

Coco-de-mer palms (Lodoicea maldivica) produce these monster nuts, which are a type of seed. The biggest can tip the scales at up to 18 kilograms (roughly 40 pounds). That's about as much as a 4-year-old boy.

Please mark as brilliant

Durairajanayagam D, Agarwal A, Ong C. Causes, effects and molecular mechanisms of testicular heat stress. Reproductive biomedici
harkovskaia [24]

Temperature affects spermatogenesis, which functions best at body temperatures just a little lower than those.

<h3>Abstract:</h3>

To keep testicular temperatures below those of the body core, adequate thermoregulation is essential. The process of mammalian spermatogenesis and the resulting spermatozoa are negatively impacted by elevated testicular temperature. Therefore, sperm quality can be affected and the likelihood of infertility is increased by thermoregulatory dysfunction resulting in heat stress. This article reviews a variety of internal and external factors that may lead to testicular heat stress. We go into more detail on how heat stress affects the spermatogenesis process, the resulting epididymal spermatozoa, germ cells, and the alterations that result in the testis.

We also go over the chemical reactions of germ cells to heat exposure and potential processes, such as apoptosis, DNA damage, and autophagy, that could lead to heat-induced germ cell damage. Further explanation is provided for the intrinsic and extrinsic processes involved in the complex mechanism of germ cell death. These intricate apoptotic pathways ultimately result in the demise of germ cells.
