What is the role of a pioneer species in primary succession?

to destroy parasites
to create shade
to provide fruit
to create the soil

Answers

Answer 1
The correct answer is to create the soil

This is called normalizing the habitat. The pioneer species in primary succession inhabit the never before inhabited place and start creating conditions for other organisms to join.
Answer 2

Answer: to create the soil

Explanation:

An ecological succession can be define as a series of changes that occur in the biotic community with respect to the changes that occur in the abiotic or non living factors such as soil, temperature, water, natural calamity and others  in a particular time duration until the ecosystem attains stability.

A primary succession is an initial stage of succession which occurs in a land which was not previously occupied by any living species and the physical environment is not favorable to support the life initially. A pioneer species is the one which makes the environment suitable for the survival of other species. For example Lichens, they secrete acids over the rocks which causes their disintegration into particles of soil. The accumulation of soil facilitates the growth of the plants.

The term diffusion comes from a Latin term meaning "to spread apart." How is the term diffusion related to its Latin word of origin?

Answers

the term is a direct derivative. and the molecules of a certain smell or odor "spread apart" to mix with other molecules

The term diffusion is related to its Latin word of origin, which means "to spread apart", as it describes the process where particles move from a region of higher concentration to a region of lower concentration. This movement results in the particles spreading out evenly throughout the available space.

Diffusion is a fundamental concept across various fields including biology, chemistry, and geography. In biology, diffusion is vital for cellular processes, for example, the transport of nutrients and waste products across cell membranes. It describes the passive movement of molecules traveling along the concentration gradient, eventually establishing equilibrium. In geography and social studies, diffusion refers to the spread of cultural traits, ideas, or technologies from one region or group to another. This can chart the progress of societal changes and technological advancements. The rate of diffusion is influenced by several factors such as temperature and the size of the diffusing molecules, or the nature and scale of the ideas being transmitted across populations.

Competition occurs between species when _____.

they fight for mates

their niche is destroyed

they try to share the same niche

a new niche becomes available

Answers

Answer: The correct answer for the fill in the blank is- They try to share the same niche.

According to competitive exclusion principle, two species when present in the same area, try to compete for the same limiting resource like food. The species having better advantageous trait over the other survive and exclude the other one. In other words, the second species is either eliminated or shifts to some other niche.

This principle is also called Gause's principle.

Thus, competition occurs between two species when they try to share the same niche.

What is a place where poor woman and men worked separately for food from a Christmas Carol?

Answers

Final answer:

The question seems to be based on Charles Dickens' depictions of the harsh working conditions for men and women in factories during the Victorian era, though no specific place from 'A Christmas Carol' is mentioned. The conditions described are similar to those found in 'Hard Times' by Dickens, who used his work to provide social commentary on the injustices of the Industrial Revolution.

Explanation:

The place mentioned in your question is not explicitly found in A Christmas Carol by Charles Dickens. Instead, it sounds like you’re asking about the working conditions depicted in Dickens' literature, such as in Hard Times, which describes the difficult lives of factory workers. In the Victorian era, which is when Dickens wrote, poor men and women often worked in factories under harsh conditions for very little pay.

The workers were segregated by gender and were subject to long hours, with meager food as part of their compensation. Women, in particular, faced additional challenges due to unequal pay and the likelihood of being sexually harassed or exploited.

These themes are common in Dickens’ work, which sought to highlight social injustices and the plight of the poor during the Industrial Revolution. While Dickens' novels are fiction, they provide important social commentary on the realities of the time, reflecting the poor living and working conditions, as well as the limited opportunities available to women, leading to some engaging in desperate measures such as 'treating' in order to survive.

You are a scientist who discovers three new species of beetles in the jungles of South America. Describe, in detail, how a protein found in each of these beetles can be used to determine which species are more closely related ...?

Answers

Sunset, this is really similar to the question about molecular clocks you asked. The more closely related the three species are, the more similar the homologous proteins will be in each of the species.
 

Defining 'sequence similarity' is a little bit nuanced. It can refer either to the genetic code or the amino acid code. Because the genetic code is degenerate multiple codons code for the same amino acid - mutations in the gene don't result in mutations in the proteins when the mutated codon codes for the same amino acid as the unmutated codon.
 
Similarly, you can sort of think of some amino acids as being redundant. In some cases, replacement of one amino acid with another doesn't result in all that much change to the protein's structure or function. The result is, as species diverge and mutations build up, they build up preferentially in certain domains of the protein and more frequently involve replacement of one amino acid with one which is pretty much similar to it.
Since all of the three beetle species posses the protein, we can use it to determine their relations. The more differences there are in amino acid sequences and the structure of the protein, the species are more distantly related because they have diverged a long time ago.

The element hydrogen has three naturally occurring isotopes, H-1, H-2, H-3. What is the number of protons, neutrons, and electrons in H-3, or tritium?

Answers

H-3

electrons-1
protons-1
neutrons-2

Answer:

Tritium is one of the three isotopes of hydrogen which contains 1 proton, 2 neutrons, and 1 electron. Out of three isotopes, protium is the most abundant isotopic form of hydrogen constituting about 99.98 % of total isotopic form.

Tritium is a radioactive isotope of hydrogen having a half-life period of 12.3 years which is produced as a byproduct of fission in a nuclear explosion. Naturally, it occurs in a very trace amount.  

It emits the beta particle which is having very low energy so cannot penetrate the skin but can be hazardous if inhaled or get absorbed in the skin.

Which statement is an accurate description of the relationship of rocks and minerals? A. All minerals are made of rocks. B. Geologically, minerals and rocks are exactly the same. C. Knowing which minerals are in a rock can help you identify and classify that rock. D. Almost all rocks are made of three or more minerals.

Answers

Final answer:

The relationship between rocks and minerals is that identifying the minerals within a rock helps to classify and identify it; rocks consist of minerals, which are their basic building blocks. So the correct option is C.

Explanation:

The question concerns the relationship between rocks and minerals in geology. The accurate description of this relationship is that knowing which minerals are in a rock can help identify and classify that rock. Rocks are aggregates of minerals, and most rocks are composed of a few common minerals, although some rocks are made up solely of one mineral. Minerals are the basic building blocks of rocks, and identifying the minerals within a rock is a fundamental skill for geologists. While seven common minerals make up 84% of the Earth's crust, there are over 5,000 known minerals that could be present in various types of rocks, including igneous, sedimentary, and metamorphic rocks.

what is the independent variable in this experiment

Answers

Answer: yes the expert is right

Explanation:

Final answer:

The independent variable is what the researcher manipulates in an experiment to see its effects on a dependent variable, such as applying different amounts of a new fertilizer to see its impact on plant growth.

Explanation:

The independent variable in an experimental study is the factor, property, or condition that the researcher manipulates or changes purposefully to explore its effects on a dependent variable. For example, if a researcher is testing the effects of a new fertilizer on plant growth, the type and amount of fertilizer applied (the treatment) would be the independent variable. The growth of the plants, which the researcher measures, would be the dependent variable. The researcher controls and changes the independent variable and then observes any changes in the dependent variable to determine the impact. In a typical experimental setup, the independent variable is introduced to the experimental group but not to the control group, which allows the researcher to compare the effects. It is crucial to hold all other factors constant so that any observed changes in the dependent variable can be attributed to the manipulation of the independent variable. For instance, using the previous example of plant growth, light, water, and soil conditions would need to be kept constant barring the fertilizer application.

Locations in this region where major earthquakes occur are most closely associated with areas of

Answers

Hawaii. Hope this helped.

Final answer:

Major earthquakes are most closely associated with areas near tectonic plate boundaries, including the Pacific Ring of Fire, Mediterranean-Asiatic Belt, and regions where subduction occurs.

Explanation:

Locations where major earthquakes occur are most closely associated with areas near plate boundaries. Nearly 95% of all earthquakes take place along these boundaries, particularly around the Pacific Ring of Fire, which is known for a high incidence of earthquakes and volcanic activity. The Ring of Fire has convergent and transform boundaries and is home to most of the world's volcanoes. Another significant zone is the Mediterranean-Asiatic Belt, which experiences tectonic activity due to the Indian Plate colliding with the Eurasian Plate. Lastly, deep earthquakes in regions like northern Afghanistan are associated with the subduction process, where one tectonic plate is forced underneath another into the mantle.

Major earthquakes are not only concentrated directly on these boundaries but can also occur near them, on associated faults. Earthquakes are also common along divergent boundaries like mid-ocean ridges, and at transform faults such as the San Andreas Fault. Understanding the geologic setting of these regions is essential, as earthquake effects such as ground shaking, liquefaction, and landslides can significantly impact the local environments and human constructions within them.
