Nuclear medicine uses gamma rays to diagnose conditions. why is nuclear medicine considered to be relatively safe?

Answer:

False

Explanation:

An acquired trait is the character developed in an individual as a result of environmental influence. These traits are not coded by the DNA of a living organism and therefore cannot be passed on to future generations.

The respiratory control centers are located in the brainstem.

The brainstem is the region of the brain that connects the spinal cord to the rest of the brain and includes the medulla oblongata, pons, and midbrain. The medulla oblongata is responsible for controlling basic life-sustaining functions such as breathing, heart rate, and blood pressure. Within the medulla oblongata are the respiratory control centers that regulate breathing. These centers are responsible for setting the basic rhythm of breathing and monitoring oxygen and carbon dioxide levels in the blood. The pons is also involved in regulating breathing and helps to coordinate the transition between inhalation and exhalation. The midbrain plays a smaller role in respiratory control but is still involved in the process.

The brainstem is located below the cerebrum, which is the largest part of the brain responsible for conscious thought and voluntary movements. The cerebellum is also located below the cerebrum and is responsible for coordinating movement and maintaining balance. The corpus callosum is a band of nerve fibers that connects the two hemispheres of the cerebrum.

Overall, the respiratory control centers are located in the brainstem, specifically the medulla oblongata and pons, and are responsible for regulating breathing. The cerebrum, cerebellum, and corpus callosum are located above the brainstem and are involved in other functions such as consciousness, movement, and balance.

Explanation:

DNA forms purines and pyrimidines in all organisms explains why the gene of a frog may be inserted into a bacterial chromosome.

In fact, it wasn't until the early 1940s that it was made crystal evident that genes in bacteria could change spontaneously. Around that time, Avery and colleagues revealed that genetic material is chemical in nature.

They did this by extracting DNA from Pneumococcus strains and finding that each strain possessed a character for polysaccharide production.

Since of the so-called "transforming principle," which took effect after an unknown number of steps, and because Avery lacked a chemical framework for describing how DNA functions, the result was initially not widely regarded as proof of genetic exchange.

Therefore, DNA forms purines and pyrimidines in all organisms explains why the gene of a frog may be inserted into a bacterial chromosome.

Answer:

The Amazon begins 5,240 metres above sea level in the Andes Mountains of Peru as a small stream called the Apurimac River. The Apurimac joins the Ucayali River, and they join the Maranon River, the Amazon's upper branch near Iquitos, Peru, and form the main channel of the Amazon.

Explanation:

Answer:

The correct answer is - the difference in altitudes.

Explanation:

The hemoglobin in the person of Denver who lives at a higher altitude than the person who lives in Philadelphia will be much higher. This is due to the fact that at higher elevation or altitude atmospheric pressure decreases that causes hemoglobin to stick to the RBCs and that results in less oxygen level in the body.

To compensate for this low level of oxygen levels hemoglobin content need to be higher in people living at a higher elevation.

When the temperature rises, atoms and molecules move faster and collide, creating thermal energy (also known as heat energy). Thermal energy is the energy that results from the heated substance's temperature.

The atoms and molecules that make up matter are always in motion. The increase in temperature caused by heating a substance causes these particles to accelerate and collide.

The energy that arises from a heated substance is referred to as thermal energy. The more the substance's thermal energy and the more its particles travel at higher temperatures.

Biotic factors in an ecosystem are the living organisms or the participants in the foob web. They count on each other for their survival. The biotic factors in the foob web provided are the producers, consumers and decomposers. Abiotic factors in an ecosystem are rocks, soil, and water that collaborate with biotic factors to provide them with the nutrients they needed to survive. Sunlight, air, soil, and minerals are also examples of abiotic factors. Sunlight gives energy so that plants may use them i order to grow. This ultimately holds up the whole community of an ecosystem. Air also connects with plants to help them grow by providing an origin of CO2 and other nutrients.

The reason why a vaccination against smallpox virus provides long-lasting protection, whereas a vaccination against flu virus provides protection only for a limited time, is due to the differences in the way these viruses evolve and how the immune system responds to them.

A virus known as the variola virus, which causes smallpox, does not alter significantly over time. The immune system can therefore offer durable protection against the same virus strain after it has established an efficient response to the virus through vaccination. This is why smallpox vaccine offers long-lasting protection—in some cases, even a lifetime—from the disease.

Contrarily, the influenza virus that causes the flu commonly undergoes a process known as antigenic drift. This indicates that the virus can gradually acquire minor changes in its surface proteins, which gives it the ability to thwart the immune response induced by earlier vaccines. As a result, each time a new flu vaccine is required.

When making ruby-colored glass, pure metallic copper can occasionally be used in place of gold to make extremely dark, opaque red glass.

Depending on the concentration, nickel can generate glass that is blue, violet, or even black. Nickel gives the lead crystal its reddish color.

To remove the green tint from the glass, manganese dioxide, which is black, is employed in a very slow process, it is transformed into sodium permanganate, a dark purple chemical.

Red glass is made with the help of gold chloride. It's unfortunate that red glass cannot be used to create gold. Glass with a blue/violet color is made using cobalt oxide.

Therefore, pure metallic copper is mixed with ordinary glass to make red and black glass in place of gold to make it extremely dark.

It is expected to find the highest rate of primary productivity in the tropics during the fall (Option C).

The expression 'primary productivity' makes reference to the amount of biomass produced in an ecosystem by producer autotrophic photosynthetic organisms such as plants.

Primary productivity largely depends on the process of photosynthesis by which producers can generate carbohydrates by means of solar radiation.

The measure of primary productivity of a particular ecosystem is defined by the amount of energy that is transformed by photoautotrophic organisms such as plants and algae.

Explanation:

The best-supported claim by the information is that humans deliberately introduced the silver carp as a way to solve an environmental problem. Silver carp, also known as Asian carp, was initially introduced to the United States in the 1970s by humans to control the growth of algae in aquaculture ponds and wastewater treatment facilities.

Silver carp is a filter feeder that feeds on plankton, and it was anticipated that it would help manage the growth of algae in these systems. As a result, it was believed that the silver carp would be a useful tool in solving the issue of water pollution caused by the increase of organic waste and fertilizers in the water.

Silver carp has since been established in rivers and waterways, where it has shown to be an invasive species and a threat to native fish populations. It has caused substantial economic and environmental harm by interfering with fishing activities, reducing the quality of water recreation activities, and competing with native fish species for food and habitat.

Consequently, the deliberate introduction of silver carp can be seen as an example of unintended consequences, where the introduction of an organism to solve one problem leads to another problem.
