Answer: A) Tactile cells anchor the skin to the underlying structures of the body.
Explanation:
Tactile cells are present over the surface layer of the skin on the epidermis and dermis. These cells are distinguished from the cells that lie in the underlying organs. These cells will help in determining the touch stimuli.
<u>Answer</u>: B.The heliocentric model shows that Earth revolves around the Sun. The geocentric model shows that the Sun revolves around Earth.
The geocentric model is also known as the Ptolemaic model and had as center of the Universe Earth. However, the heliocentric model presented by Nicolaus Copernicus and Galileo Galilei, had the sun as the center of the Solar System, with Earth orbiting around it. However, it is thought that this theory was older than Copernicus.
The antimicrobial activities in the mouth are hydrochloric acid denatures proteins and killing many microbes.
The capability of an hydrochloric acid activating pathogen-killing compounds is not a part of insect immunity,There has recently been an increase in interest in trehalose metabolism for therapeutic applications due to trehalose's relevance in numerous pathogenic species.The most significant biosynthetic process is the enzyme TPP (trehalose-6-phosphate phosphatase) (OtsAB).
Here, five important nematode and bacterial pathogens' recombinant TPPs, including three new members of this protein family, are compared for their enzyme characteristics.
The kinetics of the hydrolysis of trehalose-6-phosphate show that all five enzymes display burst-like kinetic behaviour, which is characterised by a decrease in enzymatic rate beyond the pre-steady state.
The observed super-stoichiometric burst amplitudes can be explained by many global conformational changes that occur in members of this enzyme family during substrate processing.

<em>For example,</em>
<em> consider a mountain whose summit is 5,000 feet (1,500 m) in elevation, but somewhere on the way up, the trail goes back down 250 feet (76 m). ... </em>
<em>If one hikes over five hills of 100 vertical feet each, the cumulative elevation gain is 5 × (100 feet (30 m)) = 500 feet (150 m).</em>

<span>Gene Expression is the progression wherein the
information from a gene is used in the combination of a functional gene
product. In eukaryotic cells, genes are delimited by repressors as well as by transcriptional
activators. The repressors will muddle to the specific DNA sequences and will constrain
transcription.</span>
