Another trait in pea plants that follows a simple inheritance pattern is flower colour. Purple flowers are a dominant trait while white flowers are a recessive trait.

Explain what this difference means in terms of the alleles for flower colour.

Answers

Purple flowers are a dominant trait, so a pea plant only needs one allele for purple flowers in order to have the trait. White flowers are a recessive trait, so a pea plant needs two alleles for white flowers in order to have the trait. If a plant has both a dominant allele and a recessive allele then the dominant trait of purple flowers will be expressed.

When a trait has two separate gene-level versions, there are dominant and recessive traits. The trait that emerges initially or is most obviously displayed in the organism is its dominant trait. Recessive traits are those that are present in the organism but are not visible at the gene level.

The allele that results in a purple flower must be dominant (PP) if a purple and a white flower are crossed and the majority of the offspring are purple. As a result, only the offspring who contain both alleles for white will truly be white (pp). An example of this would be a purple flower, which may have an allele for  white but would be purple due to presence of a purple allele (Pp). this type of individual will be heterozygous dominant.The characteristics of an offspring can be easily determined using dominant and recessive alleles.

Alzheimer's disease: piecing together the evidence assignment

Answers

Answer:


Alzheimer's disease is a neurodegenerative disease that usually starts slowly and progressively worsens. It is the cause of 60–70% of cases of dementia. Gradually, bodily functions are lost, ultimately leading to death. The cause of Alzheimer's disease is poorly understood. Other risk factors include a history of head injury, clinical depression, and high blood pressure. Initial symptoms are often mistaken for normal aging. Exercise programs may be beneficial with respect to activities of daily living and can potentially improve outcomes. Behavioral problems or psychosis due to dementia are often treated with antipsychotics, but this is not usually recommended, as there is little benefit and an increased risk of early death.

Explanation:

The course of Alzheimer's is generally described in three stages, with a progressive pattern of cognitive and functional impairment. Detailed neuropsychological testing can reveal mild cognitive difficulties up to eight years before a person fulfills the clinical criteria for diagnosis of Alzheimer's disease. These early symptoms can affect the most complex activities of daily living. The most noticeable deficit is short term memory loss, which shows up as difficulty in remembering recently learned facts and inability to acquire new information. Subtle problems with the executive functions of attentiveness, planning, flexibility, and abstract thinking, or impairments in semantic memory can also be symptomatic of the early stages of Alzheimer's disease.

Why is the Sky Blue? and Why does Helium Make your Voice go Funny

Answers

Answer:

Explanation:

Usually, the sound waves your vocal cords produce travel through air in your voice box. But when they go through the helium that you've inhaled, they travel about three times faster. That's because helium is so much lighter than air. When sound waves speed up but their frequency stays the same, each wave stretches out.

Answer:

the sky is blue because of the atmosphere and helium does that because it changes the air in our vocal tract and consequently, the speed of sound waves of our voice increases resulting in a squeaky and funny tone.

When a neuron is at rest, the charge difference between the inside and the outside of the axon is -70 millivolts (mV). This value is the ________ of the neuronal membrane.

Answers

The resting membrane potential  is the difference in voltage  through the neuronal membrane when the cell is at rest. -70 millivolts (mV) value is the _resting potential_ of the neuronal membrane.

What is the resting membrane potential?

The resting membrane potential is the difference in voltage through the membrane between the neuron interior and exterior when the cell is at rest. This is when the neuron is not sending electric signals.

When the neuron is at rest, most ion channels are closed except for K+ channels, which let the ions get out of the cell according to its concentration gradient. Na+ channels remain closed.

Hence, when the neuron is at rest, the membrane is much more permeable to potassium ions (K+) than to other ions, such as sodium (Na+) and chlorine (Cl-).

This value is the _resting potential_ of the neuronal membrane.
