Answer: Doctors will still use other drugs that are known to treat tuberculosis, even if they are less effective than the common drugs.

Tuberculosis (TB) is a disease caused by bacteria that are spread through the air from one person to another. TB  affects not just the lungs, but other parts of the body (the brain, the kidneys, or the spine). In most cases, TB is treatable and curable; however, sometimes drug-resistant tuberculosis occurs when the drug can no longer kill the TB bacteria. In such case, doctors will use other drugs that are known to treat TB, even if they are less effective than the commonly available drugs.

usefulness and profitability

Usefulness and profitability are the qualities of a mineral that classify it as an "ore".

This implies when the Geologist's who considered minerals, they characterized them. Its gauges in the grouping are intended to demonstrate components and metals that can productively be separated from a shake.

All organisms require resources to grow, reproduce, and survive. All the resources are limited. Hence, organisms compete to get the resources. Competition is an interaction which takes place among organisms whenever two or more organisms require the same limited resource.  

Ecological interactions can be intra-specific or inter-specific. Intra-specific interactions are those that occur between individuals of the same species, while interactions that occur between two or more species are called inter-specific interactions.  

Competition between organisms plays an important role in ecology and evolution, it serves to limit organism population and thereby ensure its sustainability and survival.

The time period during which imprinting occurs is the 'sensitive period'.  It is a specific time right after birth or hatching where an animal learns to recognize its own species. This behavior often affects their behaviors later in life.

The period of time during which imprinting occurs is the sensitive period. Imprinting is a rapid form of learning that occurs in a specific time period, usually soon after birth or hatching, which enables an animal to recognize its own species. It often determines behaviors later in life. The concept of the 'sensitive period' in imprinting was proposed by ethologist Konrad Lorenz. He showed that the rapid learning process happens in a limited, very specific period of time, making imprinting a phenomenon of the sensitive period.

To differentiate between options, a fear period is a time of particular sensitivity to fear stimuli, often seen in young animals. The training period is rather a human-defined concept for when learning might be most effective, and the socialization period refers to the period when social skills and behaviors are learned, but those are not exclusive to imprinting.

Final answer:

The twice-daily movement of ocean waters, known as tides, is caused by the Moon's gravitational pull on Earth, leading to two high tides and two low tides each day due to the rotation of Earth through tidal bulges.

Explanation:

The movement of water rising slowly and covering the land twice a day, then falling back is called tides.

This phenomenon is caused by the Moon's gravitational pull on Earth, which varies in different locations.

Tides are significant as they demonstrate the dynamic nature of Earth's oceans, resulting from the gravitational forces exerted by the Moon and, to a lesser extent, the Sun.

These tidal forces create two tidal bulges on opposite sides of the Earth.

As the Earth rotates, any given point on the Earth's surface experiences these bulges, leading to two high tides and two low tides every day.

This movement is crucial for coastal marine ecosystems and affects human activities such as fishing and navigation.

Answer:

C) tissue.

Explanation:

The epithelium is a tissue.

Epithelial tissue is one of the four basic types of animal tissue. Formed by juxtaposed cells, among which there is little extracellular substance. Since your cells have no blood vessels, nutrients are received through the underlying connective tissue.

The lining epithelial cells are joined with each other through structures called cell junctions. The various types of junctions serve not only as adhesion sites, but eventually also as seals preventing the flow of materials through the intercellular space, and they can also offer channels for communication between adjacent cells. Therefore, from a junctional point of view, junctions can be classified as adhesion junctions, tight junctions and communication junctions (gap junctions). In many epithelia several junctions are present in a constant sequence from the apex to the cell.

Given: Flourine 23 has a half life of 2.2 seconds. Amount of Flourine 23 present at the beginning is 400 gm.

To find: The amount of Flourine 23 left after a duration of 11 seconds.

Solution:

The number of half-lives that 400 gm of Flourine 23 has to go through can be found by the following way,

[tex] \frac{T}{T_h_a_l_f_-_l_i_f_e} = \frac{11 seconds}{2.2 seconds} = 5 [/tex]

So the 400 gm of Flourine 23 will undergo 5 half lives and with each half-life the amount gets divided by 2 or reduces by half.

400 gm -> 200 gm -> 100 gm -> 50 gm -> 25 gm -> 12.5 gm

∴ 12.5 gm of Flourine 23 will be left after 11 seconds.

Answer:

Carbon, Hydrogen, Nitrogen, and oxygen  

Explanation:

Trophic levels are the way ecology uses to organize the organisms that make up a food chain, where mass and energy transfer occurs between individuals or populations. The components of these chains can be simplistically divided into three broad groups: producers, consumers and decomposers. Foods that are involved in trophic levels have as their main elements carbon, hydrogen, nitrogen and oxygen. These elements are present at all trophic levels and are responsible for helping energy move from one trophic level to another.

Answer:

The clearer the water, the less threatened it is with the full body plate fish.

Explanation:

The correlation between the clarity of the water and the occurrence of the full body plate trait, is that the clarity of the water determines how much of the full bady plate fish will exist in that environment.

This is because the full body plates are dark colored, the less clear the lake water has, the easier it will be for these fish to survive because they will be able to camouflage themselves more easily. However, the greater the clarity of the water, the more affected the camouflage will be, causing a great threat to the existence of this fish.

Explanation:

Lactic acid is produced during lactic acid fermentation, a process used by certain bacteria and animal muscle cells under low-oxygen conditions, catalyzed by lactate dehydrogenase. In muscles, lactic acid is transported to the liver for conversion back into pyruvic acid for energy.

Lactic Acid Fermentation

Lactic acid is produced during a process known as lactic acid fermentation. This process is carried out by certain bacteria, such as those found in yogurt, and by animal muscle cells, like those in humans, during intense physical activity when there is not enough oxygen available for aerobic respiration. The key chemical reaction in this process is Pyruvic acid + NADH → lactic acid + NAD+, and it is catalyzed by the enzyme lactate dehydrogenase (LDH). In muscle cells, this process allows them to continue producing energy even when oxygen levels are low, although it can lead to the temporary accumulation of lactic acid in the muscles. Ultimately, the lactic acid must be transported via the blood to the liver, where it can be converted back into pyruvic acid and used for further energy production.

Explanation:

Mining the surface have specific consequences. Since that is at the surface, air is gonna contaminate rapidly because of all those factors that don't belong to that context. Also, the soil is gonna be damaged, because to do mining activities you have to dig, changing the structure and consistency of the surface.

Moving from underground mining to surface mining carries health and safety implications for miners, environmental impacts, and socio-economic consequences. The environmental effects include pollution and biodiversity loss while socio-economic challenges may arise due to increased investment and community response.

Moving from underground mining to surface mining entails several significant consequences. First, it impacts the health and safety of miners. Underground mining entails working in very dangerous conditions, such as high temperatures, poor ventilation, and risks of explosions and cave-ins. Many miners in the past have either died or suffered severe injuries due to these conditions.

Environmental impact is another major consequence of shifting to surface mining. The extractive industries like mining can cause substantial environmental damage, causing potential harm to local communities and their livelihoods. Toxic chemicals can leach into soils, contaminating crops and water sources, and air pollution can increase due to the burning of fossil fuels. This can lead to climate change and reduction in biodiversity.

Surface mining also brings socio-economic challenges due to the increased investment required, leading to the emergence of bigger business-driven mining operations. This can lead to greater urban stability and infrastructure but may also provoke protests and demands for accountability from local communities.

Agriculture solely is responsible for the source of food, shelter and clothing in our modern world. It has been so since pre-historic times. The role in which agriculture plays has further been expanded to capture newer dimensions.

Proper agricultural management and distribution of food helps to alleviate the problem of food shortages in societies today. Most growing communities are located in hinterlands due to the availability of land for farm practices. If produce fails to reach the buying and dependent communities, there would be acute food shortage. To the farmers, they will incur loss through spoilage of produces.

Proper management bridge this gap.
