Malik was out walking on a hot day and then decided to go inside an air conditioned
aev [14]

Answer:

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.

Chemoreceptors

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.

Thermoreceptors 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

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.

Nociceptors 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.

Oksi-84 [34.3K]

Explanation:

<u>q= 0.566</u>

Homozygous individuals have two copies of the same allele for a gene. Homozygous dominant individuals carry two copies of the dominant allele, while homozygous recessive individuals carry two copies of the recessive allele.

Further Explanation:

DNA sets contain genes that may have different forms named alleles. DNA, which is the genotype, is transcribed into mRNA and later translated into amino acids which are connected together by rRNA to form proteins which constitute the phenotype of an organism. DNA sequence mutations form new allles, impacting the resulting mRNA, and thus the encoded protein. Within species, there may be adaptation, along with genetic drift, preferential breeding, and natural selection.

Within a population certain alleles are fixed over time. In Hardy-Weinberg-allelic frequencies, the equilibrium for a particular gene is not undergoing evolution, being stable for several generations. Mutations, during this time affect the corresponding mRNA, and thus the encoded protein. Evolution may occur within populations, along with genetic drift, selective mating, and natural selection.

Over time, certain alleles become fixed within a population. Equilibrium for a specific gene is not undergoing evolution in Hardy-Weinberg-allelic frequencies are stable for several generations. During this period, mutations do not occur within the population, this is shown as

p^{2} + 2pq +q^{2} = 1   ....(eqn i)

where...

p represents the dominant allele frequency

q represents the frequency of the recessive allele

q^2 = the genotypic frequency of the homozygous recessive

p^2= the genotypic frequency of the homozygous dominant

2pq= frequency of the heterozygous genotype

and simply p+q= 1                  ...(eqn ii)

The allelic freq. of r is denoted by q and the allelic frequency, R is denoted by p...

The total number of individuals= 32+ 68= 100

Thus q= √q^{2}= homozygous recessive individuals  (white flowers)

Since there are 32 white flowering plants , freq rr= 32÷ 100= 0.32

...thus q^{2}=0.32

   and q= √ q^{2}= √0.32= 0.566
