You are correct the answer is c
Answer:
c) allowing an organism to adjust to changes in environmental conditions
Explanation:
A stimulus can be defined as any change in the external or internal environment that produces a corresponding response in the organism. These responses enable the organism to maintain an internal equilibrium (homeostasis). Gene expression in prokaryotes, which are the simplest forms of life, is highly regulated by environmental stimuli. Some examples of stimuli known to regulate gene expression patterns in prokaryotic organisms are light, water, pressure, temperature, etc.
Answer:
Hormones are substances produced by glands (or organs) that regulate bodily functions and behavior. Steroid hormones are one type that are chemically similar to each other, but may have different biological functions. For example, the adrenal glands produce an anti-inflammatory steroid similar to cortisone.

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.
She was suggested to increase calcium phosphate and reduce soda content because acidic soda dissolves the calcium phosphate of the teeth.
Explanation:
Calcium phosphate is an important mineral which keeps the teeth firm and strong. If calcium phosphate is not present in adequate quantity it will cause the teeth to become soft and easy for cavities to get formed.
Calcium phosphate naturally repairs the teeth by remineralization process.
Soda contains phosphoric and citric acids which dissolve the protective layer of calcium phosphate of the teeth and makes it brittle causing increased cavities.
