Disease or disorder that affects the nervous systems
Answer:
There are many diseases/disorders that affect the nervous system, but here are a few:
Alzheimer's disease
Parkinson's disease
Epilepsy
Stroke
Explanation:
Alzheimer's disease: Alzheimer's disease is a progressive disease (gets worse and worse overtime) that destroys your memory. When a person has Alzheimer's disease, their neurons (nerve cells) get damaged and eventually die all throughout the brain. Some problems people with this disease can experience are: getting lost easily, personality/behavior changes, memory loss (obviously), and need help with self-care and daily things.
Parkinson's disease: Parkinson's disease is a progressive disorder that affects one's movement. Because the nerve cells are damaged, the dopamine (type of neurotransmitter) levels decrease. Since dopamine can control your body movement, it makes it hard to balance, and you're usually stiff. It usually begins with a tremor in your hand.
Epilepsy: Epilepsy is a neurological disorder where neuron activity in the brain gets disturbed, resulting in a seizure. Epilepsy is usually genetic or gained through a trauma or stroke (brain injuries). During these seizures, people often lose consciousness. Most epileptic people are sensitive to lights (flashing and flickering especially).
Stroke: A stroke occurs when your blood supply to your brain is interrupted/stopped. This is a SERIOUS emergency. Cells can die from lack of blood and the resulting lack of oxygen. Most warning signs of a stroke include: numbness + weakness, trouble speaking, loss of balance, and dizziness.

An apple, potato, and onion all taste the same if you eat them with your nose plugged
Answer:
the flavor will neutralize
Explanation:
if you're plugging your nose, it blocks most of the taste out of a food item. so while biting into an onion while plugging your nose, it will neutralize the strong flavor and make it taste more like an apple or potato since they have very similar textures. hope this helps!

How does the biodiversity in a food chain compare to the biodiversity of a food web?
Answer:
ExpWhat is Biodiversity?
Biodiversity and food webs
Biodiversity is referred to as the web of life because many microorganisms, plants and animals interact with each other. The relationship among species is an important part of biodiversity.
A food chain is a sequence of who eats whom. The usual order of a food chain is sunlight, plants, herbivore, omnivore and/or carnivore. In one type of farming food chain, green grass and wildflowers use sunlight to grow in a field maintained by a farmer called a pasture. A Billy (boy) or Granny (girl) goat grazes on these delicious plants in the pasture. A goat or any other plant-eating animal is called an herbivore. Animals that rely on the farmer for food and protection are domesticated. In turn, the goat provides milk, meat and wool for the farmer, his family, and others. Humans are omnivores, as they eat plants and animals. The goat also provides fertilizer. Microorganisms decompose the goats’ poop or excrements, which provides fertilizers for the grass and flowers to grow. This is one example of a simple food chain based only on green plants, goats, microorganisms and humans. Millions of food chains exist around the world. Food Chain
Food chains that are related in an ecosystem form a food web. In forest ecosystems, many types of herbivores eat the trees and other plant life. Carnivores, or meat-eating animals such as tigers, lions, and wolves, prey on herbivores. They usually prey on wild animals. Sometimes, if the habitats or homes of carnivores are destroyed, they may also attack goats, sheep or cows for food. For example, in India, farmers may lose their goats to tigers; in Eastern Africa, cows may provide lunch for lions and in Western Canada, wolves sometimes attack the domesticated sheep. Carnivores are an important part of biodiversity because they regulate herbivore populations so that they do not eat their favorite plant species to extinction.lanation:
In a hypothetical population of butterflies, a dominant mutation in an allele that controls wing color has resulted in purple spots developing on the wings. The genetic change is heritable such that the offspring of butterflies who inherit at least one mutated allele will develop purple spots. The population of butterflies inhabits a windy field that contains many purple flowers. Individuals with purple spots are so well camouflaged on the purple flowers that they are eaten less frequently by predators. There are other fields with populations of the same species of butterfly nearby, but purple flowers are less prevalent in these nearby habitat areas. There are no borders between these fields and it is common for individuals from one population to be blown into another population by the wind. Despite the advantage the mutated allele confers to the butterflies in the field with many purple flowers, the mutated allele never occupies 100% of the gene pool and the population of butterflies always contains a mix of individuals with and without purple spots. What is the most likely explanation for why this trait does not spread entirely throughout the population
The movement of alleles into a population is called gene flow. The most likely explanation for why this trait does not entirely spread in the population is 'outside alleles enter the population through gene flow'.
Gene flow is caused by the migration and further reproduction of individuals in the population, or the transport of gametes from one population to another (e.g., the transport of pollen by pollinating bees).
Gene flow is an evolutionary force capable of modifying allele frequencies in a population.
In this case, despite the evolutionary advantage that the mutated allele confers to the butterflies, the frequency of this allele can not reach 100% due to the continued introduction of alleles from other populations (i.e., due to gene flow).

the wing of a penguin is ________ the arm of a human.
The wing of a penguin is homologous to the arm of a human.
Homologous organs refer to organs of different organisms that are structurally similar but functionally different.
The wing of a penguin and the arm of a human are structurally similar because they are both built on the same pentadactyl or five-digit plan.
Despite the structural similarity, the wing of a penguin and the arm of a human are adapted for different functions. While the wings of a penguin are used to propel the animal in water by flapping them together, the arms of a human are adapted for several functions, including swimming when necessary.

The negative membrane potential in a resting neuron is primarily due to :___________
a. high levels of chloride ions in the cell. diffusion of potassium out of the cell.
b. a higher permeability of the membrane for potassium compared to sodium.
c. both diffusion of potassium out of the cell and a higher permeability of the membrane for potassium compared to sodium are correct.
Answer:
c
Explanation:
When the membrane of the neuron is in a state of rest, the interior of the cell has a more negative charge in relation to the exterior, therefore option "c" is correct.
What is the membrane potential in a resting neuron?It is a phenomenon that occurs when the nerve cell membrane is not altered by action potentials.
Characteristics of a resting neuronThe resting potential is determined by the concentration gradients of the ions, both inside and outside the neuron, and by the permeability of the membrane.When a cell is at rest, the potassium channels are open, the potassium will tend to flow outwards (K ions), they are positive charges, therefore the cell interior will be negative with respect to the cell exterior.Therefore, we can conclude that the resting potential of a membrane occurs when they are not transmitting signals.

during which stage of meiosis does the diploid parent cell become four separate haploid cells?
Answer:
To summarize, meiosis is a cellular process in which a diploid parent cell divides into four haploid daughter cells. One very important event in meiosis is crossing over, which occurs between prophase and metaphase I. Crossing over increases genetic variation. The haploid cells produced through meiosis are otherwise known as gametes.

on an island there are three mice populations. Population 2 cannot contact populations 1 and 3. What name is given to this situation?
Answer:
Isolation
Explanation:
On a island, there are three mice population in which one population cannot contact other populations. This situation is an example of allopatric speciation.
What is Allopatric speciation?Allopatric speciation is also referred to as geographic speciation. It is also called vicariant speciation. Allopatric speciation is a mode of speciation which occurs when the biological populations become geographically isolated from each other to an extent that it prevents or interferes with the normal gene flow in a population.
There are several factors which are required for the allopatric speciation to take place such as isolation of a population, time, and natural selection in an environment. Earthquakes, floods, and migration all are the ways through which a group of individuals of the same species can become isolated.
