Answer:
Nitrogen fixation
Explanation:
Certain soil bacteria, e.g., <em>Azobacter spp</em> can combine free nitrogen of the atmosphere with oxygen to form nitrates. This is called <u>nitrogen fixation</u>. Other nitrogen-fixing bacteria such as Rhizobium form symbiotic unions with the roots of leguminous plants called root nodules. They fix nitrogen to form nitrates which are used up by the host plant. Nitrifying soil bacteria, e.g., <em>Nitrobacter </em>convert nitrites to nitrates in a process called <u>nitrification</u>.
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.

Cells need both genes, and each cell inherits half of the genes from both cell parents.
Answer:
The progeny produced is 100% heterozygous individuals.
Explanation:
Remember that in Mendel crosses, there are two alleles for each character, in this case for the color of the flowers.
When the problem refers to pure varieties, it refers to individuals with two equal alleles for the same gene.
If two pure varieties with antagonistic characters intersect, 100% of heterozygous individuals will be obtained in the offspring.
As for its phenotype, it will depend on which allele is dominant over the other.
