I believe the inability to make saliva would affect digestion drastically. The first phase in the process of digestion comes with saliva - it breaks down some substances in your mouth, because it contains amylase which helps during this process. If it weren't for saliva, you probably wouldn't even be able to swallow food - and even if you did, it would be almost impossible to break it down in your body.
Provide structure and support, facilitate growth through mitosis. allow passive and active transport, produce energy, create metabolic reactions, aids in reproductive.
Global warming is a phenomenon of rising the average temperature of the earth over the past 100 years.
The following would provide the best evidence to support the claim :
(A) Habitat loss would occur, leading to a decline in species diversity.
<h3>Global warming has a long term impact on the ecosystem</h3><h3 />
- The earth warming gases are carbon dioxide, methane, nitrous oxide, etc.
- As the earth will warm up, we will experience more extreme weather, heatwaves, and droughts.
- Due to heat, the glaciers are melting to a high extent.
- Due to the melting of the glaciers, the sea level is rising.
- Some animals are already experiencing extinction due to global warming.
- Due to the loss of habitat, there is a loss of diversity.
Thus, the correct option is: (A) Habitat loss would occur, leading to a decline in species diversity.

Answer:
In in vitro plant tissue culture, indolbutyric acid and other auxins are used to initiate root formation in a procedure called micropropagation. The micropropagation of plants is an asexual propagation or propagation technique that is based on the organogenetic potential of plant cells, which consists of cultivating in vitro on appropriate substrates, isolated cells, portions of yolk meristems, vegetative apices at the beginning of their development or microstaquillas. Small samples of plants used are called explants. Auxins such as indolbutyric acid can be used to cause mass formation of undifferentiated cells called corns. Callus formation is often used as a first step in the micropropagation process since, by exposure to certain auxin hormones, callus cells can be induced to form other tissues such as roots.
Indolbutyric acid is often used to promote the rooting of stakes. In a study in Camellia sinensis, the effect of three different auxins, indolbutyric acid, indolacetic acid and 1-naphthalenacetic acid on root formation was measured. According to the authors, indolbutyric acid produced a higher root yield compared to other auxins.9 This effect of indolbutyric acid is consistent with that found in other studies; This hormone is considered the most commonly used auxin for root formation, 10 because it is much more potent than indolacetic acid and other synthetic auxins.7
Jatropha curcas is a species in which there is an improvement in the quality of the rooting of the stakes with the addition of indolbutyric acid in the middle (longer root length, number of roots, percentage of rooted stakes, and dry root weight) , 11 although not always the effect on rooting is statistically significant.
