Answer:
The same reptile known as a river turtle in Illinois is called a cooter in Florida. This language phenomenon is classified as regionalism.
Explanation:
Regionalisms are words, expressions or attributions of meanings whose use is exclusive of a specific geographical area.
In the English language, those words or expressions of a locality or region that are not used in other places because there is an equivalent or they have a different meaning from the original are considered regionalisms.
The language phenomenon where the same reptile is referred to as a "river turtle" in Illinois and a "cooter" in Florida is classified as a dialect (Option C).
Dialects are variations in language specific to particular regions or social groups. They encompass differences in vocabulary, grammar, and pronunciation. In this case, the term "cooter" is a regional variation used in Florida to describe the same type of reptile that is called a "river turtle" in Illinois.
This difference highlights how language evolves and adapts to local cultures and environments, leading to distinct regional expressions for the same objects or concepts. Unlike synonyms, which are different words with similar meanings used within the same dialect, dialectal variations reflect the unique linguistic identity of specific areas, making "dialect" the correct classification for this phenomenon.
Complete Question:
The same reptile known as a river turtle in Illinois is called a cooter in Florida. This language phenomenon is classified as:
A) Synonym
B) Homonym
C) Dialect

Animals that migrate great distances would obtain the greatest energetic benefit of storing chemical energy as _____.
fats - hope this helps!!
Animals that migrate long distances benefit greater from storing energy as fat. This ensures survival when food availability decreases and allows for a relatively constant body temperature in cold seasons.
Explanation:Animals that migrate great distances would obtain the greatest energetic benefit of storing chemical energy as fat, which is housed in specialized adipose tissues. Fat provides a more efficient long-term energy system, especially for the animals like elk who increase their metabolic activities and thus energy needs in winter. As such, having a threshold level of energy stored as fat in their bodies can ensure survival when the availability of food decreases. Furthermore, the heat generated from metabolism and stored as fat can help in maintaining a relatively constant body temperature, a characteristic of endotherm animals.

Normal blood pressure is 120/80. Which best describes the blood pressure reading?
The first number (120) is the systolic blood pressure. This is the pressure reading once the heart pumps, send a large volume of blood coursing through the artery and causing there to be more pressure in the artery at that moment.
The second number (80) is the diastolic pressure. This is the pressure reading after the heart has pumped and is refilling with blood. The diastolic reading is lower than the systolic reading because there is a lower volume of blood flowing through the artery after that initial pump from the heart, and therefore there is less pressure in the artery.
***see attached pic***
Answer:
The systolic pressure is 120, and the diastolic pressure is 80.

1. The right answer is in a discontinuous manner.
During DNA replication, the DNA polymerase synthesizes complementary DNA by mating on both strands, since the two strands are antiparallel, the replication is bidirectional, which means that one of the two strand is synthesized in a direction opposite to that of the direction of the enzyme, to do this, the DNA polymerase is obliged to synthesize DNA in the form of small fragments which are called Okazaki fragments, and its synthesized discontinuously (these fragments are not glued together by phosphodiester liasons, it is only after that another enzyme will intervene to ligate these fragments (DNA ligase).
Alice wants to see if she can enhance percent fertilization in her sea urchin experiment. She hypothesizes that depleting Calcium (Ca2+) from the sea water will increase percent fertilization. Alice begins by isolating the eggs from the female in salt water (SW) and Calcium-free salt water (CFSW) and then washes the eggs three times in SW or CFSW, respectively. She sees that she has more eggs in her SW group. After doing this, she isolates sperm from the males, dilutes the sperm into equal aliquots and adds a drop of sperm into each of her egg samples. Assume that all sperm and eggs were stored under the same conditions. After an hour, under the microscope she observes that her SW eggs has a higher percent fertilization compared to her CFSW eggs. This contradicts her hypothesis. 1a. What confounding variables could account for error in Alice’s experiment? (Choose three

How is extra nitrogen getting into the ecosystem
Extra NITROGEN can be leaking into the atmosphere through the NITROGEN cycle. The nitrogen is the most in the air at the moment so the nitrogen cycle takes the nitrogen round and it's leaked back out in different forms
The extra amount of nitrogen get back into the ecosystem by the combustion of fossil fuels and the use of nitrogen-containing fertilizers in the agriculture of crops.
What is Nitrogen cycle?The nitrogen cycle moves nitrogen element back and forth between the atmosphere and the living organisms. Bacteria are responsible for the change of nitrogen gas from the atmosphere to the different nitrogen compounds such as ammonia, nitrate, nitrite which the roots of plant can absorb. Other bacteria which can change nitrogen compounds back to nitrogen gas, helps this gas to re-enter the atmosphere.
In general, human activities release nitrogen into the environment by the two main processes which are combustion of fossil fuels and the use of nitrogen-containing fertilizers in agriculture. Both of these processes increases the level of nitrogen-containing compounds in the atmosphere.

Answer:
the flow of energy in an ecosystem
the eating patterns of organisms
how much energy is transferred from one organism to another
Explanation:
A food web is an interconnection of multiple food chains and a practical representation of what-eats-what in an ecosystem, while a food chain is a linear sequence of how nutrients and energy (in the form of food) are transferred from one organism to another organism in an ecosystem. A food web contains many interconnected food chains. A food web or food chain provides information about how organisms are connected, the eating patterns of organisms, and the flow (or the amount) of energy that is transferred from one level to another through different organisms in an ecosystem.
) Which of the following statements about transcriptional regulators is false? (a) Transcriptional regulators usually interact with the sugar–phosphate backbone on the outside of the double helix to determine which DNA sequence to bind. (b) Transcriptional regulators will form hydrogen bonds, ionic bonds, and hydrophobic interactions with DNA. (c) The DNA-binding motifs of transcriptional regulators usually bind in the major groove of the DNA helix. (d) The binding of transcriptional regulators generally does not disrupt the hydrogen bonds that hold the double helix together.
The false statement is: (a) Transcriptional regulators usually interact with the sugar–phosphate backbone on the outside of the double helix to determine which DNA sequence to bind.
Transcriptional regulator or factor is protein with the ability to control and regulate gene expression at the transcription level by binding to DNA. Transcriptional factors have domain-DNA-binding domain which contains structural motif that recognizes DNA and it is responsible for the attachment to specific DNA sequence. It usually binds to the DNA major groove (hydrogen bonding) because it is less degenerate than that of the DNA minor groove.
Transcriptional factors also contain trans-activating domain for the binding of other proteins and signal-sensing domain for the detection of external signals.

Let’s consider a different scenario. In this case, the moths live in a forest where they have no predators. Caterpillars (which are baby moths) have a limited amount of food available to them, so they compete with other caterpillars to get enough food. Researchers have made a hypothesis that caterpillars with larger mouth parts are able to obtain food faster than those with smaller mouth parts. They believe that having larger mouth parts is a favorable trait, and that caterpillars with this favorable trait are more likely to live long enough to reproduce and pass this genetic trait on.
Using complete sentences, answer these 3 questions:
1. What data would researchers need to collect in order to start to test their hypothesis?
2. In order to see the effect of natural selection on the caterpillar population, what data would researchers need to collect later?
3. Why would researchers need to collect data at least 2 different times?
Hypothesis:
Caterpillars with larger mout parts are able to obtain food faster than those with smaller mouth parts.
1. -
For scientists to be able to test the hypothesis they need enough information which they will obtain through studies and observation. What they'll have to do is compare small-mouth caterpillars, big-mouth caterpillars and moths - they'll have to find out if the moths came from big-mouth or small-mouth caterpillars.
2. -
Scientists will have to go to the forest and look for caterpillars and observe them. If the ratio of big-mouth caterpillars is higher, it means that for now, the hypothesis is correct and that natural selection is being applied.
3. -
To assure that it wasn't a coincidence or that the mouth-size survival was due to a different factor, they'll have to collect a second wave of data, that needs to be compatible with the first one for the hypothesis to be proved correct.

Winds generally flow away from the equator and toward the poles. What transfer does this flow of wind cause? A. an energy transfer, with heat energy moving toward the equator B. an energy transfer, with heat energy moving away from the equator C. a water transfer, with water moving from the atmosphere to the ocean D. a water transfer, with water moving from the ocean to the atmosphere
Answer:
B
Explanation:
The equator receives more of sunlight throughout the year, compared to increasing latitude, hence the atmosphere and oceans within this latitude are warmer. When winds blow away from the equator, they transfer this heat energy to the cooler higher latitudes.
Answer:
D
Explanation:
The equator receives more sunlight than the poles and the air is heated more at the equator. Wind is created because of this uneven heating. Winds generally travel away from the equator, with the flow of wind transferring heat energy away from the equator.
