The drug methotrexate belongs to the group of drugs known as antimetabolites. By reducing the growth of cancer cells, methotrexate treats cancer. In order to prevent the development of scales, methotrexate slows the growth of skin cells in psoriasis. Methotrexate may treat rheumatoid arthritis by reducing immune system activation.
Methotrexate obstructs the creation of DNA. This prevents cell division and growth, which slows or stops the growth of cancer. Cancer cells are more vulnerable to this harm because they divide more quickly and with less error-correcting than healthy cells do.
Acute lymphoblastic leukaemia (ALL), especially ALL that has progressed to the central nervous system, can be treated with methotrexate sodium alone or in combination with other medications.

Explanation:
the cells transporting substances from the interior of the cell then to the exterior of the cellBiodiversity is important for the sustainability of ecosystems. However, many of the human actions that are aimed at growing communities are decreasing the biodiversity of these areas, leaving populations and ecosystems vulnerable. As human populations grow, the terrestrial and aquatic ecosystems they use may be transformed by the efforts of human beings and biodiversity losses typically accompany these processes. Which of these actions decrease biodiversity and threaten sustainability? Select ALL that apply.
A Regulated hunting seasons artificially decrease hunted populations, often leading to extinctions.
B Decreased use of pesticides and fertilizers can allow for increased damage to plant life.
C Invasive (non-native) species may outcompete native species for food and habitat.
D Habitat destruction reduces or eliminates the food resources and living space for most species.
E Pollution from building and commercialization can create health problems in exposed organisms.
Habitat destruction reduces or eliminates the food resources and living space for most species. So the correct option is D.
What is biodiversity?The diversity of animals, plants, fungi, and even microorganisms like bacteria that comprise up our natural environment are all included in what is known as biodiversity.
These many species and critters collaborate in complicated web-like ecosystems to keep things in balance and support life. All of nature that we require for survival, including food, fresh water, medicines, and shelter, is supported by biodiversity.
We run the danger of disturbing the equilibrium of ecosystems and losing biodiversity as people put more and more strain on the world by utilising and consuming more resources than ever before.

Let's remind ourselves of what we predicted last week:
Go to question 4 on Lesson 7 and review what you predicted would happen to the populations of the buffalo and wildebeest after
1975.
Lesson 7 question 4 # is
4. Could these discoveries help predict the patterns we may see in the population size due to things like the emersion and elimination of the rinderpest? Based on our simulation results what do we predict will happen to the populations of the buffalo and wildebeest after 1975?
Yes, these findings are pretty helpful in predicting trends in population growth that might result from situations like the advent and eradication of the rinderpest. The outcomes of the simulations we performed to forecast what will happen to the buffalo and wildebeest populations after 1957 it will go back to normal.
1. Revisit your prediction from Lesson 7. What information would you need to know in order to determine if your prediction was correct? Explain why the information would help determine if your prediction was correct.
Answer: My hypothesis is correct because in the 1960s, the buffalo population in Serengeti National Park, Tanzania, began increasing at a rate much faster than before. Scientists determined that this increase was due to several factors, including the eradication of a disease called rinderpest and this how I think my hypothesis is correct.

Why does oil not dissolve in water?
-Water molecules form hydrogen bonds with each other and exclude oil molecules.
-Oil molecules covalently bond together, forming droplets that separate from water.
-Water molecules do not form strong attractions to nonpolar molecules, like the ones in oil.
-Oil is less dense than water, which causes it to separate from water instead of dissolving.
Water molecules make hydrogen bonds with each other, it exclude oil, which is a hydrophobic substance.
what are the properties of water molecule ?It is a polar molecule which is odorless, more transparent; Its nucleus contain the oxygen atom of water attracts electrons than the nuclei of the hydrogen atoms of the molecule
There are different property of water molecule like strong cohesive property in which the attraction of molecules is referred to as cohesion.

Which statement best represents how structure relates to function?
(A) A deer's horizontal pupils help it scan the horizon for predators.
(B) People can develop a tolerance for spicy food over time.
(C) Tortoises in the wild can live for more than 150 years.
(D) Labrador retrievers can be black, yellow, or chocolate colored.
A deer's horizontal pupils help it scan the horizon for predators. Option A is correct.
The statement "A deer's horizontal pupils help it scan the horizon for predators" best represents how structure relates to function in this context.
Structure-function relationship is a fundamental concept in biology that explains how the physical attributes (structure) of an organism are adapted to perform specific tasks or functions. In option (A), the horizontal pupils of a deer are its structural feature that is specifically adapted to serve the function of scanning the horizon for predators. Horizontal pupils provide a wider field of view, allowing the deer to monitor a larger area for potential threats. This adaptation enhances the deer's survival by increasing its awareness of its surroundings and the ability to detect predators early.
Options (B), (C), and (D) also relate to biological concepts but do not directly exemplify the concept of structure-function relationship as explicitly as option (A). While option (B) talks about human adaptation to spicy food and option (C) discusses tortoise longevity, they do not emphasize the direct connection between a specific structural feature and its function. Option (D) discusses color variation in Labrador retrievers, which is more about genetic diversity rather than a structural adaptation tied to a specific function.
In summary, the relationship between the structure (horizontal pupils) of the deer and its function (scanning the horizon for predators) in option (A) best illustrates the concept of how organisms' physical attributes are shaped by natural selection to perform specific tasks essential for their survival and success in their environment.

A volcanic eruption covers a wide area of forest with ash lava and volcanic rock which of these describes the first stage of ecological succession that will begin to return biotic factors back to the forest community and return it to a state of equilibrium
The process of primary succession will take place to return the forest to a state of equilibrium.
After an earthquake or volcanic eruption, lichens break down the rocks to produce new, nutrient-rich soils. This process is known as primary succession. Pioneer species are the first species that settle a region following a significant disturbance; they contribute to shaping the new ecosystem. Primary succession happens when new land is created or rock is exposed, such as after a volcano eruption like the ones on Hawaii's Big Island. New land is continuously being generated as the lava flows into the ocean. Every year, the Big Island gains about 32 acres of new land. First, certain hardy plants and lichens with little soil requirements, known as pioneer species, can develop because weathering and other natural forces degrade the substrate sufficiently.Therefore, option C. is correct.

The debate the founding fathers had over legislature was?
The debate that the founding fathers of America had over the legislature was known as the Great Debate.
The change from the Articles of Confederation to the United States Constitution wasn't smooth, and there were numerous lengthy discussions both before and after the convention to address the issues with the earlier document. But one thing was clear, something needed to change. The Constitutional Convention of 1787 brought together fifty-five delegates to discuss the best ways to modify the existing text.The Federalists and the Anti-Federalists represented opposing viewpoints in the Great Debate. The Anti-Federalists opposed the ratification of the Constitution, whereas the Federalists did. The inclusion of the Bill of Rights was one of the main topics of discussion between these two parties. The Federalists claimed that this amendment was unnecessary since, as written, the Constitution merely limited the powers of the government, not the people. The Anti-Federalists argued that without a Bill of Rights, the populace would be vulnerable to despotism and that the Constitution granted the federal government an excessive amount of power.Learn more about the US Constitution here:

Steroidal hormones enter the cell directly and interact with DNA inside the nucleus. These hormones change gene expression, affecting the RNA that is produced and the proteins that are translated in a cell. Nonsteroid hormones do not enter the cell. Instead, they bind to specific receptors on the outside of the cell membrane. This triggers molecules called secondary messengers, such as cAMP, to begin their work of relaying information in the cell, where other chemicals, messengers, and proteins are involved to create a cellular response.

A. 100 Joules
B. 0.1 Joules
C. 10 Joule
Using the 10% rule when studying trophic pyramids, if the primary consumers obtain 100 Joules of energy from the autotrophs Carnivores receive an energy transfer of 10 Joules.
Trophic level is referred to as the level of an ecosystem as well as a nutritive chain or food chain.
What does the trophic level 10% rule mean?
The trophic level 10% rule states that only 10% of the energy in an ecosystem will be transferred from one trophic level to the next.
Based on their eating habits, a chain of organisms is separated into various tiers. The producers, or green plants, make up the first and lowest stratum, the primary consumers or the herbivores make the 2nd trophic level and the carnivores or secondary consumers make up the 3rd trophic level and within these energy is transferred.
In this question, the herbivores obtain 100J of energy from autotrophs now according to 10% law only 10% of this energy will be transferred to carnivores thus,
10 = [tex]x[/tex]/100 ×100

Answer:
Is honey hypertonic?
Image result for what is tonicity of honey
Honey is 70 to 80% sugar and this high percentage causes hypertonic conditions that may lead to lysis of microbial cell walls.
Explanation:
hope this helps
Honey is hypertonic, meaning it absorbs water quickly. As a result, it can keep a tear dry and draw off the fluid that bacteria require to survive.
What is tonicity?Tonicity is a solution's ability to change the volume of cells by changing their water content. When water enters a cell, it can cause hypotonicity or hypertonicity when it exits the cell.
Hypotonic fluid contains less fluid, sugars, and salt than blood. Hypertonic fluid contains more fluid, sugars, as well as salt than blood.
Isotonic fluid, sugars, and salt concentrations are the same as those found in blood.
Honey is hypertonic, which means it quickly soaks up water. As a result, it can keep a tear dry as well as draw off the fluid required by bacteria to survive.
Honey has such potent antibacterial properties that it can treat severe conditions such as MRSA, which is recognized to be resistant to conventional antibiotics.
Thus, it can be concluded that honey is hypertonic.
