What helps in taste in tongue ?Tongue helps in the tasting via the help of taste buds which are recognized and interpretation of various taste.
The nasal cavity of nose is made up of many chemo receptors where the names of the receptors are :
olfactory
vomeronasal
and trigeminal systems.
The presence of chemoreceptors in the nasal cavity is in the anterior respiratory epithelium of the nasal cavity.
Olfactory receptors that are abstractly found in the nasal cavity that is responsible for the interpretation of smell. It is the protein that is capable of binding to the odour molecules.

Answer:
The correct answer would be A
Explanation:
The picture shows the PMAT process Prophase occurs first the chromosomes become visible as paired chromatids and the nuclear envelope disappears.
Then the Metaphase. The way you can remeber that s by looking at the first letter which is M. Stands for Midlle. So you can say the chromososmes are in the middle together. Now Anaphase. The way you can remember that is by looking at A meaning Away. You can think of that as the chromosomes being pulled away from each other moving opposite ways. Now last is Telophase. That when they make two nuclei. When they are divided into 2 there are not nucleus anymore but nuclei.
Hope this helps :)

What is a cell?
The smallest unit of life is a cell. There are biomolecules in it. Every living thing is composed of several cell units. Different sorts of creatures contain various types of cells.
Prokaryotic cells are the most basic types of cells; they are only seen in unicellular organisms, do not engage in cell division, and lack real cell organelles and a nucleus, instead having DNA coiling up in the cytoplasm.
Eukaryotic cells are higher cells that contain cell organelles and have the capacity to carry out a variety of intricate tasks required by big organisms.
Thus, Cell signaling is a method of communication between or within cells, and a change in a cell's activity is conveyed as a signal that may set off a chain of events so that the body can respond appropriately.

Answer:
Synapsis...
Hope that helps!
Explanation:
During prophase I of meiosis, these pairs form a tetrad in a process called crossing over or recombination. Tetrad is formed with the help of the alignment of two homologous chromosomes.
What do you mean by Meiosis?Meiosis may be defined as a process where a single cell divides twice to create four cells comprising half the original amount of genetic information.
In prophase I of meiosis, the two homologous chromosomes align in such a way that it undergoes crossing over, which synthesizes four chromatids of two chromosomes and leads to the formation of the tetrad.
Therefore, during prophase I of meiosis, these pairs form a tetrad in a process called crossing over or recombination.

What is significant drawback to transferring electricity produced by solar where sunshine is abundant to states where it is not
Answer:
The transfer could only occur during the day because it cannot store solar energy.
Explanation:
The transfer of electricity produced from solar energy only occurs during the day because it cannot store solar energy at a tremendous level. At homes, we can easily store the electricity made from solar energy with the help of batteries but for providing electricity to a state where thousands of houses are present, enormous batteries are needed to store it which can't be made because of very high cost so that's why the solar energy can not be stored.

There is an amusement park based on sea life. Its purpose is to get the public interested and caring about conservation of the world’s oceans. Some of the profits from this organization go toward funding ocean research and conservation. In order to get people interested, some of the shows that the park offers include large marine mammals that do tricks. Some of the larger marine animals are housed in pools for viewing instead of being allowed to live in their natural habitat. They also have rare and endangered species on display to help increase awareness of them. They even have a breeding program for the some of the endangered animals.
Describe an ethical concern that would be related to this park.
Answer:
The animals may rely on humans for care instead of doing it themselves
Explanation:
Think about it, if the animals there don't have all the resources they need in a tank instead of the ocean. So they need the workers there to care for them. This can be bad for the animals because if they can go back to the ocean, they won't be able to get the resources they need by themselves!

In short terms, A & C are the only answers that have anything to do with the magnetic field. Solar wind is part of solar weather, and is involved in the creation of the other three answers. Auroras are formed through the interaction of solar wind and the oxygen & nitrogen in Earth's atmosphere.
The geomagnetic storms and auroras are the results from the interaction of solar weather on Earth's magnetic field. The correct options are A and B.
What are solar weathers?Solar or space weather refers to actions that take place on the Sun's surface.
These reactions usually have different effects on our planet, owing primarily to the Earth's magnetic field, which acts as a shield for the planet.
A geomagnetic storm happens when the solar radiation collides with the Earth's electromagnetic field, causing disruptions in the magnetosphere.
The interaction of loaded solar particles and the land based electromagnetic field produces an aurora, which is a luminescent formation.
The solar wind transports these particles to the terrestrial electromagnetic field, in which they are shown in various colors depending on the type of particle.
Thus, the correct options are A and B.

They are able to adapt and to live in the same environment without competing with each other. How are they able to share habitat and food resources?
Two species of sea urchins live practically side-by-side in sandy bottoms. The two species appear to have the same diet: drift seaweeds and other bits of organic matter. They can live in the same environment without competing.
As it compels them to live in the same environmental surroundings so the characteristics of living nature also get developed as their current following situation that's helping them to get the same food & habitat.
Both species of sea urchins share the same habitat and food resources by separating their niches a little bit differently from one another.
What do you mean by Habitat?Habitat may be defined as a type of native environment for which a particular species is best adapted due to natural selection.
Competitive exclusion leads to the elimination of any one species until they do not share different niches.
Therefore, both species of sea urchins share the same habitat and food resources by separating their niches a little bit differently from one another.

The immune response works much like a team with different players playing their role for a common goal: to rid the body of a pathogen.
Create an analogy that helps explain the roles of the specific and nonspecific responses of the immune system and describe the relationship between the two responses
Answer:
In a primary immune response, naive B cells are stimulated by antigen, become activated, and differentiate into antibody-secreting cells that produce antibodies specific for the eliciting antigen.
A secondary immune response is elicited when the same antigen stimulates memory B cells, leading to the production of greater quantities of specific antibodies that are produced in the primary response
