which of the following is not an example of homeostasis? A. after plunging into icy cold water Gary's core body temperature rapid drops. B. while exercising Julie has heart rate and breathing increase the balance to increase oxygen used by her muscle cells. C.on a hot day Martin doesn't drink very much water heater kidneys respond by removing very little water from his blood resulting in yellow concentrated urine. D.after eating a candy bar April's pancreas secretes insulin causing extra blood sugar to be removed PLZ ANSWER QUICKKKK
All the options except A are examples of homeostasis, where the body maintains internal stability. In option A, Gary's temperature drops rapidly due to the icy water, which is a failure to maintain homeostasis.
Explanation:Homeostasis refers to the process of maintaining a stable internal environment within an organism, despite the changes in external conditions. The body's various systems engage in a constant dance of adaptation and recalibration, keeping key factors like temperature, glucose levels, and water content steady. Failure to do so can lead to detrimental health effects, or in severe cases, possibly death.
Among the options you mentioned, A. 'after plunging into icy cold water Gary's core body temperature rapid drops' is not an example of homeostasis. This is because homeostasis involves maintaining internal equilibrium. In this case, Gary's body temperature is rapidly dropping due to the icy water, rather than being maintained at a stable level.
Option B, C, D describes the body's efforts to maintain stable heart rate, hydration, and blood sugar levels respectively – all of which are examples of homeostasis.

What cell type must enter a female clams body in order for glochidia to form
Answer:
Sex cells or reproductive cells
Explaination:
Freshwater clams are hermaphrodites and produce both eggs and sperm.
So the freshwater clams reproduce by releasing their reproductive cells (sex cells or gametes) into the water column. The sex cells then enters the female clams body and undergo internal fertilization and produces glochidia. The glochidia then released in the surrounding water.
Hence, the sex cells are responsible for the reproduction of female clams.
Carbon cycles in nature can be balanced, so the concentration of CO2 in the atmosphere stays relatively constant. However, if the total amount of trees and other plants increased worldwide, CO2 levels in the atmosphere would decrease. Explain why.
Answer:
During Northern Hemisphere spring and summer months, plants absorb a substantial amount of carbon dioxide through photosynthesis, thus removing it from the atmosphere and change the color to blue (low carbon dioxide concentrations).

A scientist has a very small sample of DNA. To analyze the DNA, which would be the MOST USEFUL first step for the scientist to follow?
A. Use restriction enzymes to make multiple copies of the DNA.
B. Use the polymerase chain reaction (PCR) to make multiple copies of the DNA.
C. Transfer the DNA into bacteria, and allow the bacteria to be replicated many times.
D. Use restriction enzymes to cut the DNA into many small pieces.
The correct answer is option (B).The most useful first step for analyzing a very small DNA sample is to use the Polymerase Chain Reaction (PCR) to make multiple copies of the DNA. PCR allows for rapid amplification of DNA, providing sufficient quantities needed for subsequent analyses like restriction enzyme digestion and gel electrophoresis.
To analyze a very small sample of DNA, the most useful first step is to use the Polymerase Chain Reaction (PCR). PCR is a widely used technique in molecular biology that permits rapid amplification in the number of copies of specific DNA sequences. This method follows the principles of DNA replication, allowing for the exponential increase of DNA in a short period to generate large quantities necessary for analysis, making it extremely useful in various applications such as research, forensic investigations, and clinical diagnostics.
Restriction enzymes are used to cut DNA into pieces based on specific sequences, which can then be analyzed using gel electrophoresis. However, without enough copies of DNA, restriction enzyme digestion is not viable. Inserting DNA into bacteria is another method of DNA amplification but is more time-consuming compared to PCR.

Will the carbon atom's journey ever end?
Yes, it will eventually be used up
No, it will continue cycling through the Carbon cycle forever
Yes, it will eventually run out of energy
The journey of a carbon atom is a continuous cycle. It doesn't end or run out of energy but continues to be recycled in the Carbon cycle.
Explanation:The journey of a carbon atom through the carbon cycle is considered to be an ongoing process that continues indefinitely, not something that ends. This is because the carbon cycle is a closed system with carbon continuously being recycled from the atmosphere, into living organisms, and back again. It is important to note that a carbon atom doesn't 'run out of energy', instead it is transferred and transformed through various chemical reactions during its journey through the cycle.

The carbon cycle consists of a number of biotic (living) and abiotic (nonliving) factors that act as carbon reservoirs, or locations where more carbon is stored than released. Carbon travels constantly from reservoir to reservoir, sometimes stopping for a very long time and sometimes stopping for only a short time. Which of the following are abiotic carbon reservoirs?
(choose all that apply)
oceans
animals
atmosphere
fossil fuels
sun
decomposers
Answer:
Fossil fuels
Atmosphere

Explanation:
The following are abiotic carbon reservoirs: oceans, atmosphere, fossil fuels, and the sun. As abiotic substances don't reproduce like animals and plants, while biotic organisms can,
What is the carbon cycle?The carbon cycle is the process by which carbon is exchanged among the Earth's atmosphere, oceans, land, and living organisms. Carbon is constantly moving between these reservoirs through various processes, such as photosynthesis, respiration, and decomposition. Abiotic (non-living) reservoirs are locations where carbon is stored, but there is no biological process associated with them. The carbon cycle maintains the rate of photosynthesis too.

The last section of the article shows the severity of ocean acidification and it’s devastating effects on marine and human life by:
A.stating several facts
B.making a comparison
C.providing a detailed image
D.asking rhetorical
The last section of the article likely demonstrates the severity of ocean acidification by potentially employing methods like stating facts, making comparisons, providing images, or posing rhetorical questions. Ocean acidification, mainly caused by atmospheric CO2, has grave implications for marine ecosystems and human life.
Explanation:The student's question is referring to how the severity of ocean acidification is portrayed in the last section of an article. Highlighting the article's strategy for conveying the impact on marine and human life could involve different methods. For instance, presenting several facts would offer hard data illustrating the effects, while a comparison might show the contrast between the present state of oceans to past conditions. Providing a detailed image could visually depict the damage, and utilizing rhetorical questions might engage the reader to think critically about the issue.
Ocean acidification is a significant global issue caused primarily by atmospheric CO2 dissolving in ocean water. This results in a lower pH value in oceans, making them more acidic, and adversely affects many marine species by reducing the availability of calcium carbonate, crucial for building shells and skeletons. If CO2 concentrations continue to rise, corals and other marine life could face severe declines, impacting marine ecosystems and the humans who rely on them.
