Cora might have been diagnosed with another disease that presents similarly as tardive dyskinesia (this disease is a common adverse effect of antipsychotic drugs). Her misdiagnosis is most likely Sydenham's Chorea which affects people with rheumatic fevers. Other differentials include seizures and essential tremors.
Certain fossils, called index fossils, help geologists match rock layers. To be useful as an index fossil, a fossil must be widely distributed and represent a type of organism that existed for a brief time period. Index fossils are useful because they tell the relative ages of the rock layers in which they occur.
Answer
I added 4 and 5 as an attachment due to time constraint.
Explanation:
1. at a steady state ca2+ taken by vesicle = 40n/mol
enclosed volume of CSR = 5μ/mg
concentration of ca2+ in vesicle =
40*10⁻⁶/5x10⁻⁶
= 0.008
= 8x10⁻⁹mol/L
2. radius of circle =75nM
volume = 150nm
volume of vesicle = 4/3 x pi x r³
= 1.33 x 3.14 x (75x10⁻⁹)³
= 1.77 x 10⁻²¹
when we convert this we get
1.77x10⁻¹⁸L since 1m³ is equal to 100oL
surface area =4x3.14x(75x10⁻⁹)²
= 12.56x5.625⁻¹⁵
= 7.065x10⁻¹⁴m²
this is 7.065x10⁻¹⁰cm²
3. number of vesicle/CSR
= 5x10⁻⁶/1.77x10⁻¹⁸
= 2.824x10¹²
surface are = 2.824x10¹² x7.06x10⁻¹⁰
= 19.95x10²
Answer:
64
Explanation:
Since the population is in Hardy-Weinberg equilibrium and the equilibrium is defined by the equation
p² + 2pq + q²
where the frequency of the homozygous dominant allele F ( feathers on the leg ) = p²,
F of homozygous ( featherless legs) = q²
F of heterogyous ( carrier of featherless allele) = 2pq
F (q²) = 128/200 = 0.64
q = √0.64 = 0.8
and p + q = 1
p = 1 - 0.8 = 0.2
2pq = 2 × 0.2 × 0.8 = 0.32
number of chickens that are heterozgous for the feathered leg allele = 0.32 × 200 = 64
Answer:
Option A. Air pollution can cause water pollution.
Explanation:
Substances can permeate into the water from the air.
