Hand sanitiser, bactirea killing wipes, gas mask, gloves hasard suit, ect
but washing your hands is good too XD
Answer:
B. only chemoreceptors, mechanoreceptors, thermoreceptors, and nociceptors
Explanation:
Receptors are chemical structures, that receive and transduce signals that may be integrated into biological systems.
Receptors that can be found in the mouth include: chemoreceptors, mechanoreceptors, thermoreceptors, and nociceptors.
<u>Chemoreceptors</u>
These are receptors that detects chemical stimuli, either molecules or ions dissolved in liquids. An example would be our taste buds in the mouth, because they respond to specific molecules or ions in our ingested food.
<u>Thermoreceptors</u> responds to changes in temperature. These receptors are present in the oral cavity, skin and hypothalamus.
Mechanoreceptors are receptors that respond to distortion of the plasma membrane that occurs due to touch, pressure, vibration, stretch, stress or strain
. They can be found in the mucosae of ginviva (gum), cheek, tongue and soft and hard palate.
<u>Nociceptors</u> are receptor responds to painful stimuli. The purpose of nociceptors is to inform the body of injury, damage or threat of damage to body tissues so that a response may be made. They can be found in the tooth pulp and within dentine cavity.
On higher areas such as hills or mountains
Answer:
Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON). Nucleic acids such as DNA and RNA contain carbon, hydrogen, oxygen, nitrogen, and phosphorus (CHON P).
Explanation:
Answer:
Meiosis is the process of development of gamates in sexually reproducing organisms. Both males and females use meiosis to produce their gametes. In females the process of meiosis is called oogenesis as it produces oocytes which further develops into ova (eggs) and in males spermatogenesis takes place to produce sperms. Meiosis takes place in the germ cells of the organism. Meiosis is also known as reduction division as a diploid cell reduce to develop 4 haploid daughter cells. Prophase I is the initial phase of meiosis. This phase has six substages, therefore it requires more time to complete especially in oogenesis. During prophase I homologous chromosomes pair exchange their DNA this process results in chromosomal crossover. The new combination of DNA in the cross over chromosomes will be a source for genetic variations with production of new combination of allele. In metaphase I homologous pair of chromosome move together along a metaphase plate , microtubules emerge from the spindle and attach at the kinetochores near the centromere of each chromosomes. Microtubule from one side of the spindle attach to one of the chromosome in the homologous pair and that of other side attaches with other chromosome of each pair. Because of microtubules chromosome pair align at the metaphase plate (equator of the cell). The random alignment of chromosome pair at the equator plate will result in different proportion of transfer of genes from maternal and paternal chromosomes. This is the law of independent assortment, hence this will result in genetic diversity in the daughter cells.
