Hi can someone please help me answer these 2 questions?

What is the function and purpose of the phosphorus cycle?

What are electromagnetic waves? Including Reflection, refraction and transmitted.

Answers

Answer 1

Answer:

The phosphorus cycle is the process by which phosphorus moves through the lithosphere, hydrosphere, and biosphere. Phosphorus is essential for plant and animal growth, as well as the health of microbes inhabiting the soil, but is gradually depleted from the soil over time.

Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields.

They are also perpendicular to the direction of the EM wave

What conditions are necessary for rocks to melt? ( I’ll give a Brainliast) please answer

Answers

Answer:

The rock is pulled down by movements in the earth's crust and gets hotter and hotter as it goes deeper. It takes temperatures between 600 and 1,300 degrees Celsius (1,100 and 2,400 degrees Fahrenheit) to melt a rock, turning it into a substance called magma (molten rock).

Answer:

Flux melting occurs when water or carbon dioxide is added to rock. These compounds cause the rock to melt at lower temperatures. This creates magma in places where it originally maintained a solid structure. Much like heat transfer, flux melting also occurs around subduction zones.

if the checkpoint finds an error, what are some actions the cell can take to ensure the error does not get replicated?

Answers

Answer:

If the checkpoint mechanisms detect problems with the DNA, the cell cycle is halted, and the cell attempts to either complete DNA replication or repair the damaged DNA. If the damage is irreparable, the cell may undergo apoptosis, or programmed cell death 2.

Explanation:

um i think this is correct. hope this helps and have a nice day

-KindnessMatters-

The cell cycle is the intricate process of replication of genetic material and producing the daughter cells. The cell cycle is regulated by several mechanisms, one of which is checkpoints.

Checkpoints are the sites where the cells are checked for errors and inaccuracy in the cell.

The cell takes action to ensure errors are not replicated as:

The G1 checkpoint in the cell cycle is the primary checkpoint, which decided whether the cell should divide or not divide. It checks for size, DNA damage, and nutrients. The cell cycle will halt if there will be any errors.

The G2 checkpoint is involved in the overall smoothening of the cell cycle. If any damage is observed after the other checkpoints, the cell cycle will pause in the G2 phase, halting the replication of errored genetic material.

The M checkpoint corresponds to accurate attachment of the sister chromatids and the cycle will be in pause if the proper attachment is not done.

Thus, there are several checkpoints to check the errors in the DNA, and if any error persists, the cell cycle will be halted.

Explanation:

Humans cycle carbon from the biosphere to the atmosphere by respiration, driving cars that use gasoline for fuel, eating plant parts, planting vegetable crops. So, all these processes are playing a major role in the carbon cycling by Humans.

What is Carbon Cycle?

The movement of carbon from the reservoir to reservoir is known as the carbon cycle. The carbon Cycle occurs through the atmosphere, oceans, and through living and dead organisms.

Humans during respiration inhale Oxygen and exhale Carbon-dioxide, vehicles also emit smoke consisting mainly of carbon, plants' bodies also contain a proportion of carbon.

Therefore, Humans cycle carbon from the biosphere to the atmosphere by respiration, driving cars that use gasoline for fuel, eating plant parts, planting vegetable crops. So, all these processes are playing a major role in the carbon cycling by Humans.

Efforts to reduce pollution began occurring later in the century. If pollution near factories was reduced, what would happen to the color of the moths? Explain your answer.This would happen because

Answers

Answer:

moths would begin becoming lighter as the pollution is reduced

Explanation:

The color of the moths would begin becoming lighter as the pollution is reduced. This is because during the time of high amounts of pollution industrial melanism takes place and the moth's pigmentation becomes a darker tone. This is so that the moths are able to blend in better with its surroundings and survive. Pollution causes sulphur dioxide gas and dark soot deposits which have a greyish dark tone, thats why moths pigmentation turns darker. With pollution reduced moths need a lighter colored pigment to blend into lighter colored objects such as trees and leaves.

The color of the Moths will become lighter as a result of this due to the effect

pollution has on its color.

Industries and factories make use of fuel and when it is burned in generating

sets and other equipment it produces the compound known as Nitrogen

oxide.

The Nitrogen oxide has a brownish color which goes into the atmosphere

where the moths fly in  thereby contact with the gas darkens the color  to

shades of brown. A reduction in the discharge of the gas will lead to it

becoming lighter.

Is the relationship between Riftia pachyptila and the chemosynthetic bacteria an example of symbiosis?

Answers

Answer: YES. The relationship between Riftia pachyptila and the chemosynthetic bacteria is an example of SYMBIOSIS.

Explanation:

Nutrition is the series of process by which living organisms obtain food substances and use them to provide energy and materials for their growth and maintenance. There are 2 major modes of nutrition which includes:

--> Heterotrophic nutrition: this is the type of nutrition in which the organism depends on manufactured food for survival. Heterotrophic organisms may be SYMBIOTIC which means that it can live together with another organism as they both benefit from each other.

--> Autotrophic nutrition is the type of nutrition in which an organism has the ability to manufacture its own food. This can be achieved through the process of CHEMOSYNTHESIS. In this process, they synthesis organic compounds with the use of energy from inorganic compounds such as carbondioxide. An example is the chemosynthetic bacteria found in the gut of Riftia pachyptila.

Riftia pachyptila is an aquatic invertebrate that is seen at the seafloor near hydrothermal vents ( high temperature area). They do not have digestive system that will enable them make use of the inorganic materials (carbondioxide, sulphide) found in their environment. But within their paired coelomic cavities are chemosynthetic bacteria.

The relationship between Riftia pachyptila and the chemosynthetic bacteria is an example of SYMBIOSIS because the chemosynthetic bacteria depends of the Riftia pachyptila for the necessary inorganic compounds for its own metabolic reactions and excretion of by products while Riftia pachyptila depend on the bacteria for byproducts from its metabolic reaction which is needed for its growth.

YES, the connection between Riftia pachyptila and therefore the chemosynthetic bacteria is an example of SYMBIOSIS.

Nutrition-

Nutrition is the series of processes by which living organisms obtain food substances and use them to supply energy and materials for growth and maintenance.

There are 2 major modes of nutrition which includes:

Heterotrophic nutrition is the sort of nutrition during which the organism depends on manufactured food for survival.Autotrophic nutrition is the sort of nutrition during which an organism has the power to manufacture its own food. this will be achieved through the method of CHEMOSYNTHESIS.

Riftia pachyptila is an aquatic invertebrate that's seen at the seafloor near hydrothermal vents ( heat area).

They do not have gastrointestinal system which will enable them make use of the inorganic materials (carbondioxide, sulphide) found in their environment. But within their paired coelomic cavities are chemosynthetic bacteria.

The relationship between Riftia pachyptila and therefore the chemosynthetic bacteria, chemosynthetic bacteria depends on the Riftia pachyptila for the required inorganic compounds.

For its own metabolic reactions and excretion of by-products Riftia pachyptila depends upon the bacteria for byproducts from its metabolic reaction which is required for its growth.

Answers

Answer:

Cells of the immune system are able to respond to the presence of invading organisms because they recognize the antibodies present in the invading pathogen

Explanation:

The mechanisms of human immunity can be grouped into two broad categories: the innate or nonspecific immune system, which provides a first and general defense against any element recognized as foreign, and the acquired or specific immune system that recognizes specific threatening agents and generates a response directed against those elements. When foreign substances enter our body (bacteria, viruses, parasites, proteins from other animal or plant species, cells from other organisms - including those of human origin - and a long etcetera, all of which are given the common name of antigens) and are brought into contact with cells that are members of the immune system, the foreign element or antigen is first captured by certain types of cells that are collectively known as antigen-presenting cells. These cells would correspond to the intelligence service and their mission is to take the antigens, introduce them inside, process them and present the antigens on their surface in a fragmentary way to other cells of the immune system. This results in the activation of lymphocytes that specifically recognize the antigen and ends in the development of mechanisms that mediate the physiological function of the response, that is, the elimination of the antigen. Thus, the immune response can be functionally divided into three phases: the antigen recognition phase, the activation phase of the response, and the effector phase.

Hey y'all I need help with this bio question: what are the pros and cons of different skin tones in different parts of the world?

Answers

Oh this one is so cool!

It basically all boils down to Vitamin D! We need this essential vitamin to help our body build hormones and regulate calcium. Our bodies make Vitamin D when we are exposed to the UV rays found in sunlight. But as we all know, too much sunlight isn’t good because these UV rays can harm us. Melanin (the chemical that our bodies produce to darken skin tone and hair color) provides protection from UV rays by absorbing them. However, this means that the more melanin that is produced by someone’s body results in less absorption of UV rays and a decrease in Vitamin D production. But for someone living around the equator or in the tropics that doesn’t matter because there’s lots of sun all the time. So for humans living in these areas where there’s lots of sunlight year round, it’s beneficial to have darker skin to protect from the harm of UV rays. People living in these areas still get plenty of Vitamin D though because of that year round sunshine.

Now what about those who’s skin has less melanin, such as those found in the higher latitudes? Well with less sunlight year round, their bodies had to adapt to be able to get enough Vitamin D. So less melanin is produced by the body in order to absorb the lesser amounts of UV rays to make Vitamin D. Lighter skin is, therefore, more beneficial the farther away you go from the tropics.

So essentially:
Pro of Darker Skin tones
-Protection from harmful UV rays

Con of Darker Skin tones
-Less absorption of UV rays and less production of Vitamin D

Pro of Lighter Skin tones
-Greater absorption of UV rays and more Vitamin D production

Con of Lighter Skin tones
-Less protection from harmful UV rays (resulting in sunburns and, in extreme cases, skin cancer)

This is of course the biology answer. The social impacts of different skin tones is a whole different story that you can ask in the history section.

In 2006, an Ethiopian researcher announced the discovery of well-preserved 3.3 million-year-old fossil of a young female hominid. Refer to Figure (F) below. Considering the Hominid trend of evolution, choose which skull would most likely be that most primitive of the three.

Answers

Answer:

Skull three

Explanation:

the backlining is in more, and the jaw moves out more, resembeling that of a more gorilla like creature

It sounds like the description is referring to a hominid with a more pronounced facial structure, similar to that of a gorilla. This may indicate a more primitive stage of hominid evolution, as earlier hominids had more pronounced facial features and a more protruding jaw than later, more advanced hominids.

What is the basic evolutionary changes in the group mentioned ?

As hominids evolved over time, their facial features became more refined, and their jaw became less protruding as they adapted to a diet that relied less on tough, fibrous vegetation and more on softer, cooked foods. This adaptation allowed for the development of a larger braincase and a more upright posture, both of which are hallmarks of later hominids such as Homo erectus and Homo sapiens.

It's worth noting that the evolution of hominids is a complex and ongoing area of research, and new discoveries and interpretations of existing evidence may change our understanding of the evolutionary timeline and the characteristics of different hominid species.

Over the course of hominid evolution, several important changes occurred that distinguish hominids from other primates. One of the earliest changes was the development of bipedalism, or the ability to walk on two legs. Bipedalism allowed hominids to free their hands for tool use and other tasks, and also facilitated the long-distance travel needed to explore new environments.
