I would say Nucleic Acids
Answer:
False
Explanation:
Phylogenetic analysis is a means of establishing evolutionary relationships.
Synapomorphy is a shared ("syn") character that is different from the form found in an ancestor that distinguishes a clade (monophyletic group)from other organisms
The absence of a trait can be used as a synapomorphy in phylogenetic analysis. For example, the loss of a trait, such as the loss of legs in snakes, can be a valuable synapomorphy for a clade.
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.

The right option is the second option, which states "<span>fur color that closely matches the eucalyptus bark color</span>". Change is in the fur color of Koala's to match the bark color of eucalyptus tree is a structural adaptation that fits them for their habitat as tree-dwellers.
A sperm and egg combine to make a zygote. (or fertilized egg)
So, the answer would be "A".
I hope this helps!
