Answer:

Independent - Water/Type of water (salt and pure)

Dependent - Height of plant

Controlled - Amount of water

Explanation:

Independent is what the experimenter manipulates (in this case being the type of water.)

Dependent is what the experimenter measures and is a result of the independent (in this case being the height of plant)

Controlled is what you are trying to keep the same (in this case the amount of water you give each plant.)

Answer:

your answer is 6

Explanation:

C6H12O6 + 6O2 → 6CO2 + ?H2O + Energy

H12O6---> 2 hydrogen and 1 oxygen for very water molecule. 12 ÷ 2= 6 which means 6H2O

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.
