A country that has been relatively poor is starting to become wealthier. This has brought many people into the capital city, causing the population to grow very rapidly. Many new apartment buildings, as well as water and waste management systems, are being constructed to meet their living needs.
Which other technology would be a priority for the survival of such an expanding population?
A. Better communication systems
B. Structures for growing food in or near cities
C. Modern recreational facilities
D. New methods of public transportation
Answer: Option B
Explanation:
The technology that an help in the surviving of the expanding population is structure that can grow food in or near the cities.
The basic needs of the human beings is food, space and other necessary resources.
These resources cannot be avoided and needs to be fulfilled. The lack of space and other resources is completed excluding the food.
So, there is a need of structure which can grow food in the cities or somewhere else.

Which of the following is required of a new drug?
Please help me
Answer: C it must cure a disease
Explanation I hope I was right lmk if it helps you
A new drug requires FDA approval, which involves rigorous processes including animal studies, human clinical trials, and submitting an NDA that includes comprehensive details on drug safety, effects, and administration.
For a new drug to be marketed, it is required to obtain FDA approval, which is a stringent process. Initially, manufacturers must conduct animal studies and human clinical trials to assess toxic dose levels before filing a New Drug Application (NDA). The NDA includes detailed information on drug usage, side effects, and possible drug interactions. Furthermore, it lays out guidance for how the drug should be manufactured, packaged, monitored, and administered. Patients and healthcare providers are informed about the drug's potential harmful side effects through labeling, package inserts, and publication in resources like the Physicians' Desk Reference (PDR), as well as through direct-to-consumer marketing efforts.
To proceed with clinical trials, researchers must submit an Investigational New Drug (IND) application to the FDA's Center for Drug Evaluation and Research (CDER) and wait for a 30-day review period. Should any problems arise before or during trials, the FDA has the authority to place a 'clinical hold' on the research. After successful clinical trials demonstrating the therapy's effectiveness and safety, the developers can then submit the extensive NDA for final approval.
How does this procedure serve as a method of birth control?
Answer:
Sperm cannot be delivered to the urethra.

Which was not used in support of the continental drift hypothesis? fossil evidence coastline fit of South America and Africa ancient climate composition of meteorites
Answer:
composition of meteorites
Explanation:
The continental drift theory has been based upon several evidence. The shape and perfect fit of South America and Africa is one of those evidence. The fossil records are another very strong evidence, as there are fossils of the same species on different continents that are not connected to each other in the present, and in nature is practically impossible to have the same species in different continents. The evidence about the climate also suggests that the continents have been moving, as there are remains of glaciers at places that nowadays are deserts and savannas. The meteorites are not one of the evidence though, and their composition doesn't have anything to offer in this tehory, as their composition is not related to the Earth and the processes on it.

Although air is full of nitrogen, it is not available for organisms to readily use.
Nitrogen is changed into which substances before being used by living
things?
Answer:
Nitrogen is changed into AMMONIA, NITRATES AND NITRITES before it can be used by living things.
Explanation:
Nitrogen is the most abundant element in the atmosphere, approximately 78% of the air is made up of nitrogen. Despite the abundance of nitrogen, the element can not be used directly by plants and animals.
Nitrogen fixing bacteria that are found in the soil are the ones responsible for converting atmospheric nitrogen into the forms that can be used by plants. Nitrogen fixing bacteria convert atmospheric nitrogen to ammonia while nitrifying bacteria convert ammonia to nitrates and nitrites. Plants use ammonia, nitrates and nitrites to make organic molecules.
All living organisms use nitrogen to make various compounds such as DNA, proteins, chlorophyll, etc.
After the death of the living organisms containing the nitrogenous products, dentrifying bacteria decompose the nitrates in their body to atmospheric nitrogen.
Answer: Ammonia, nitrates, nitrites - apex
After a hurricane, a small group of seabirds flew off course and formed a new
population. The allele frequencies in this new seabird population are different
from the frequencies in the original population.
What mechanism of evolution caused this change?
A. Natural selection
B. Sexual selection
C. Genetic drift
D. Mutation
Answer:
Option C, Genetic drift
Explanation:
Separation of a part of a population from the main population group there by causing reduction of allele frequency is known as founder effect and founder effect is a form of genetic drift.
For example -
A small island has a a species of plant that has red and white color flowers. Some how the plants producing white flowers got removed from the island and hence plants now only produce red flower. This incidents must have reduced the allele frequencies of both red and white flower.
Thus, option C is correct
Water passes from one living organism to another when:
A. an ocean wave splashes onto a beach.
B. a person sweats during exercise.
C. an animal eats the leaves of a plant.
D. a plant absorbs nutrients from the soil
Water is transferred from one living organism to another when an animal eats the leaves of a plant, incorporating the water contained in the plant into its own biological system. This is a direct transfer of water as opposed to processes like transpiration or ocean upwelling, which are part of the larger water cycle but are not direct transfers between living organisms. Hence, the correct option is C.
The correct answer to the question would be when an animal eats the leaves of a plant. During this process, water that was absorbed by the plant and exists within the leaves is transferred to the animal. This reflects an aspect of the water cycle where water is moved between different trophic levels within an ecosystem.
On the other hand, the transpiration process involves plants taking up water through their roots, which then moves up the plant and evaporates from the leaves, returning water back to the atmosphere, rather than directly to another living organism. Ocean upwelling is another related concept where nutrients, once part of organisms that have died, are brought back to the surface and made available again for other living organisms through the action of winds and water currents. However, it does not directly involve the passage of water from one living organism to another in the immediate sense.
Streams erode their channels by abrasion, by dissolving soluble material, and by _____. layering polishing grinding evaporation
Answer:
grinding
Explanation:
The streams are very powerful agents when it comes to erosion. With their power and chemical composition, the streams manage to erode the rocks easily and even the hardest rocks experience significant changes or are totally destroyed over time. The water of the streams manages to break down the rocks into small or big pieces, and as it does it moves them away. The rocks that are carried are constantly colliding with other rocks along the way, causing even more pieces to break and to be eroded, thus the grinding type of stream erosion.
Answer:
The correct answer is grinding.
Explanation:
The ability of a water stream to erode and transport materials that it has collected from the ground during the water cycle depends largely on the speed with which it moves. A current channel is the direction in which water moves in a current.
These currents perform erosion by lifting loose particles by abrasion, and grinding and dissolving the soluble material they collect. The faster the water moves and produces greater turbulence, it will produce greater erosion.
The three ways to transport sediments during this cycle are: in solution, in suspension and sliding or rolling along the bottom.

lipid storage
protein synthesis
photosynthesis
dna replication
atp synthesis
Answer:
ATP synthesis, through cell respiration.
The mitochondrion functions in the ATP synthesis.
Explanation:
Mitochondria helps in formation of ATP molecule with the help of the membrane bound protein known as ATP synthase. These proteins catalyzes the addition of phosphate group to the adenosine nucleotide and then add phosphate group to the previously attached phosphate group by producing a phosphoanhydride bonds. These phosphoanhydride Bond releases high energy in the system when broken. The third phosphate from adenosine releases the maximum energy followed by the the others.

why are bacteria needed in the nitrogen cycle
Bacteria, particularly cyanobacteria and rhizobia, play a crucial role in the nitrogen cycle through the process of nitrogen fixation. They convert inaccessible atmospheric nitrogen into a usable form (ammonia) for plants and animals, acting as natural and sustainable fertilizers. This process allows nitrogen to be incorporated into proteins and nucleic acids, supporting growth in terrestrial ecosystems.
Explanation:Bacteria play a vital role in the nitrogen cycle, particularly through a process known as nitrogen fixation, a biological process where atmospheric nitrogen (N₂) is converted into ammonia (NH3). Some bacteria like members of the genus Rhizobium and cyanobacteria perform this independently, while others, collectively known as rhizobia, interact symbiotically with legume plants to assist in nitrogen fixation. These bacteria, housed in specialized structures called nodules on legumes, convert atmospheric nitrogen into a form that is usable by plants and animals, essentially acting as a natural and sustainable fertilizer.
Nitrogen becomes incorporated into the proteins and nucleic acids of the organisms, leading to growth and development. The nitrogen fixation process is particularly vital as the nitrogen available in the atmosphere cannot be used directly by most living organisms. Therefore, through the conversion of atmospheric nitrogen to ammonia, these bacteria make nitrogen accessible and usable for terrestrial ecosystems.

The brain is susceptible to addiction largely because of its response when dopamine levels are high. This response primarily involves
A. reducing dopamine receptors.
B. producing more serotonin when dopamine levels are high.
C. increasing dopamine receptors.
D. producing more dopamine when induced by drugs.
Answer:
A
Explanation:
Dopamine release in the brain causes a pleasurable feeling. This system is utilized by the reward center in the brain significant in encouraging life-sustaining behaviors such as satiety. However, drugs artificially induce this region of the brain causing the subject to alter their mood. Drugs induce a higher amount of dopamine release than reward centers of the brain. The brain adjusts by reducing the number of dopamine receptors as it tries to gain homeostasis. However, this can result in addition because one steadily requires more drugs to induce the same dopamine effect. The subject, therefore, steadily becomes tolerant of the number of drugs he was taking and needs to increase the intake.

A farmer chooses to breed the cows that produce the most milk rather than the cows that produce less milk, this is an example of - artificial selection.
What is artificial selection?Artificial selection is an evolutionary process in which humans consciously select for or against particular features in organisms – for example, by choosing which individuals to save seeds from or breed from one generation to the next. People have been artificially selecting plants and animals for thousands of years.
Artificial selection to obtain cow yielding higher milk output will shift the peak to one direction, hence, will be an example of Directional selection. In stabilizing selection, the organisms with the mean value of the trait are selected. In disruptive selection, both extremes get selected.
