Rabbit is considered to be the secondary consumer

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.

It is a phenomenon that occurs when the nerve cell membrane is not altered by action potentials.

Therefore, we can conclude that the resting potential of a membrane occurs when they are not transmitting signals.

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.

A possible hypothesis here is; "If rainbow trout are eating all the macroinvertebrates, then keeping rainbow trout out of new river habitats will allow native species to recover."

A hypothesis is a statement that is tentatively put forward to explain an observation. Usually, a hypothesis is an if .... then statement. This is one of the first things that we must look out for when considering each of the statements.

Since we have observed that rainbow trout eating all the macroinvertebrates in streams and starving out other fish species, it follows that  keeping rainbow trout out of new river habitats will allow native species to recover."

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 outgroup is a distantly related group of animals used to determine the evolutionary relationships of the ingroup.

An outgroup, which differs from sociological outgroups, is a group of organisms that are more distantly connected and that is used as a reference group when assessing the evolutionary relationships of the ingroup, the group of organisms that are the subject of the study.

Looking at a closely related species that is known to be phylogenetically distinct from the group of species we are researching is known as the "outgroup comparison" strategy. It is likely that the character state in that outgroup was ancestral to the group under study.

Examples are Gibbons, Marsupials, Echinoderms, and Gymnosperms.

Answer:

f=ma

so if we are finding acceleration, we divide force by mass to get the acceleration which can be 19/26 which gives 0.73 as resulting acceleration

Hope it helps

When an object has a mass of 26kg has a force of 19N applied to it then the resulting acceleration of the object would be 0.73 meters/second².

Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum. The mathematical expression for Newton's second law is as follows,

F = ma

As given in the problem, when an object has a mass of 26kg has a force of 19N applied to it then we have to find the resulting acceleration of the object,

mass= 26 kilograms

force = 19 Newtons

Force = mass×acceleration

19 Newtons = 26 × acceleration

acceleration  = 19/26

                     = 0.73 meters/second²

Thus, the resultant acceleration of the object would be 0.73 meters/second².

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).

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:

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.

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.

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.
