Population decreases by 15.
Birth rate means more population (positive), death rate means less population (negative), immigration means more (positive), and emigration means less (negative). So, just add and subtract the appropriate numbers:
Negative 15 people means that the population decreases by 15.
Answer:
D.
Explanation:
It will stay the same no matter how the atoms are rearranged
Answer:
Explanation:
The chaparral biome has a large amount of biodiversity, which helps insulate an environment against the loss of a single species. Therefore, one would not expect the chaparral biome to be too sensitive to the loss of a single species.
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.
