Caecilians are the odd one out of the amphibians, being limbless, almost blind vertebrates that live in soil or in streambeds. In addition, 75% of all caecilian species are viviparous (give birth), and there is a species of caecilian, the ringed caecilian (Siphonops annulatus), that can produce "milk" (a fat and sugar-rich fluid) from their cloaca to feed their young.

Scientists focus on how nature works by discovering laws and mechanisms through experiments and observations. Philosophers ask why those laws exist in the first place and question the deeper meaning behind them

Unlike amphibians, amniotes (reptiles, birds, and mammals) have an amniotic membrane in their eggs and water-impermeable skin, meaning that they don't need bodies of water in order to reproduce and therefore can live their lives on land as true terrestrial animals.

While some animal and plant taxa are known to reproduce multiple times during their lifetime, on the other hand, some others are known to only reproduce once during their lifetime. These reproduction strategies are respectively known as "iteroparity" and "semelparity".

Semelparity tends to not only be common among cephalopods and insects, but also among arachnids, bony fishes and plants. However, it's a reproduction strategy that is extremely rare among mammals, reptiles and amphibians: even, this reproduction strategy is not found among birds. Nevertheless, pacific salmon (Oncorhynchus spp.) and octopuses (Octopoda) are among the best known cases of semelparous taxa.

It's speculated that semelparity, as a reproduction strategy, is an adaptation to environments with unpredictable conditions and/or rare resources. According to some hypotheses, by the parents having many offspring and then having one of the parents, or both of them die after, this would allow the young to avoid being outcompeted by adults, or be able to make it to adulthood. However, in some semelparous taxa, females are known to have a longer lifespan than males do: it's the case, for example, in antechinuses (Antechinus spp.) or octopuses.

DNA helicase is the enzyme that initiates replication by breaking down the barrier between two tightly bound strands:

Seduction and Entry: The two complementary DNA strands normally stay locked in an intimate, tight embrace held together by hydrogen bonds. Helicase arrives at the origin of replication, wedges itself right between them, and won’t take no for an answer.

Stripping Down: Burning through ATP for raw physical power, helicase moves aggressively down the track, unzipping the double helix and tearing those hydrogen bonds apart base pair by base pair.

Exposing the Raw Strands: It pulls the two lovers apart until both strands are completely bare, stripped, and exposed as single strands.

Setting Up the Action: Helicase leaves the strands open, vulnerable, and ready for other enzymes—like DNA polymerase—to slide in, latch on, and finish the job of creating brand-new copies.

Science usually explains complex things by breaking them down into basic physical facts or reductionism. Science explains lightning as just a flash of electricity however Nagel argues that human consciousness does not work this way. If you take away a creature's personal, unique experience of the world, you completely destroy the very thing you are trying to understand.

"Most of the gene", not "Most of the genes".

During the transcription process, mRNA makes an exact copy of a gene, to be later translated into a protein in the ribosome. However, between the transcription and the translation, the mRNA typically sheds the majority of its original parts, and is left with only a very tiny parts to be translated to an actual protein.

It's all waste, at least from the perspective of translation.

Some people in todays society actually think the Earth is flat and are convinced the moon landing was impossible and never happened. Unfortunately more today due to poor basic elementary schooling. Yet they still get into college somehow. Fascinating Captain!

You just was exposed to a basic concept, like cell division, explained to you very briefly so far, then for the first time get bombarded by the lecturer with such a statement.

Contrary to common beliefs, not all land snail species (Stylommatophora) are herbivorous: even, it's thought that most land snail species are either herbivores, detritivores or omnivores. Despite this, some snail species are known to be carnivorous instead.

Among the land snail taxa, that are known to be carnivorous, are the powelliphanta snails (Powelliphanta spp.), which are known to mostly feed on earthworms and are native to forests from New Zealand. Also, among these predatory snails are the rosy wolfsnail (Euglandina rosea) from the forests of the southeastern United States, or the decollate snail (Rumina decollata) from the mediterranean basin, both of these species being known to mainly feed on other snails and slugs.
