Cataplexy is a loss of muscle tone or control that is often associated with narcolepsy.
Hope this helps :)
Because you need respiration to able to function of the rest of organs
Complete question:
In pea plants, flower color is controlled by a pair of alleles where purple (P) is dominant to white (p). Stem length is controlled by another pair of alleles where tall (T) is dominant to short (t). These two allele pairs segregate independently. Suppose you have a pea plant that has purple flowers and tall stems and you wish to carry out a testcross in order to determine its genotype. Complete the predictions using the correct terms.
1. In order to carry out the testcross, you should cross your original pea plant with another pea plant whose phenotype is -------
2. If you examine 100 F₁ plants from the testcross and find that they all have purple flowers with tall stems, you should conclude that the genotype of your original pea plant is -------
3. If you examine 100 F₁ plants from the testcross and find that 44 have purple flowers with tall stems and 56 have purple flowers with short stems, you should conclude that the genotype of your original pea plant is -------
4. If you examine 100 F₁ plants from the testcross and find that 53 have purple flowers with tall stems and 47 have white flowers with tall stems, you should conclude that the genotype of your original pea plant is
-------
5. If you examine 100 F₁ plants from the testcross and find that 23 have purple flowers with tall stems, 26 have white flowers and tall stems, 24 have purple flowers with short stems, and 27 have white flowers with short stems, you should conclude that the genotype of your original pea plant is

Answer:
The blanks will be filled by following words - inside, open
Explanation:
The sentence in the question tells about the mechanism of closing of stomata in plant cells and the role of potassium ions in closure of stomata. The completed statement will be -
Potassium ions are actively pumped out of the guard cells. When K are pumped in, the inside of the cell is hypertonic relative to the outside of the cell that is hypotonic. Subsequently, water moves <u>inside</u> the guard cells, the guard cells bulge and the stomata <u>open</u>.
A. Since the frequency of the R allele is 0.85, the frequency of the RR genotype would be 0.85^2 = 0.7225.
