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

What are some examples of ways homeostasis is maintained in the pH of your blood?
The body must maintain normal blood pressure levels. To accomplish this, the brain sends signals to the heart to speed up or slow down in response to blood pressure. The lungs regulate the pH level in the body. When the pH levels in the body become out of balance, the lungs push more or less carbon dioxide out of the diaphragm.
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.
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.

Which of these is the biggest?
A: climer
B: polymer
C: monomer
D: dimer
Will give brainliest to correct answer
Polymer is the biggest of the given options.
Explanation:
The monomer is a simple repeating unit in a polymer.The monomer can combine with other monomers to give the large molecules like dimer, trimer, polymer.The dimer is a molecule in which two combined monomer units are present.A polymer is a long chain composed of several monomer units which are chemically combined together.The order of increasing size from monomer to polymer:monomer < dimer< polymer
So, from this, we can conclude that polymer is the biggest of the given options.

we would not have to worry about representing diversity is racism did not exist becasue we all would bee seen as just humans.
nobody discrimates a cat because of its colour fur
why do it for humans??
Explanation:
Diversity is crucial because it enables us to learn from one another and recognize that each person is exceptional and unique in their own way.
Thus, There are many reasons why diversity is vital in society and in different situations including the workplace, classrooms, and communities. Here are some main arguments in favour of diversity.
Enhances originality and creativity: A diverse group of people can bring a variety of viewpoints, ideas, and experiences together, which can result in more original and creative solutions to issues or obstacles.
Better decision-making: Diverse teams are more likely to take into account different points of view and strategies, which can result in better choices and better results. It Encourages learning and personal development: Interacting with folks from various backgrounds can assist people in growing.

The amount of people per square mile or kilometer of land; also called arithmetic density.
A conservation biologist has determined the status of the ecosystems in a protected area, as shown in the table below. Based on the table, which part of the pie chart represents secondary succession? Status of ecosystems Percentage of protected area Primary succession 10 Secondary succession 30 Barren land 5 Established community 55 A pie chart titled Status of Ecosystems is divided into 4 unequal parts. From largest to smallest, the parts are: D, C, B, A. Segment A segment B segment C segment D.
Secondary succession is represented in the pie chart tells about the ecosystem succession thus segment c represents most of the succession.
A secondary succession is a form of ecological succession (the evolution of an organic network's ecological structure) wherein flora and animals recolonize a habitat after the main disturbance—which includes a devastating flood, wildfire, landslide, lava flow, or human activity (e.g., farming or street or constructing construction)
What is an example of secondary succession?An instance of secondary succession is the improvement of the recent population to update the preceding network of flora and animals that has been disrupted or disturbed through an event (e.g. woodland fire, flood, harvesting, epidemic disease, pest attack, etc.
Thus it is clear that segment C in the pie chart represents the secondary succession.

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.
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.learn more about dominant and recessive traits: https://brainly.com/question/3128896
