Aquaporins are channel proteins that facilitate the transport of water across the cell membrane. One group of researchers hypothesizes that without functional aquaporins, no water will be able to enter the cell. A different
group proposes an alternative hypothesis, stating that even with nonfunctional aquaporins, a small amount of water will still cross the cell membrane. An experiment is set up in which plant cells with mutated (nonfunctional)
aquaporins and plant cells with normally functioning aquaporins are both placed in distilled water.
Which of the following data would support the alternative hypothesis?
Cells with functional aquaporins exhibit low turgor pressure and are hypertonic.
B
Cells with functional aquaporins exhibit high turgor pressure and are hypotonic.
Cells with mutated aquaporins exhibit an absence of turgor pressure and are completely plasmolyzed.
Cells with mutated aquaporins exhibit moderate turgor pressure and are hypertonic.

Answers

Answer 1

Answer: D

Explanation:

Answer 2

The data that would support the alternative hypothesis are cells with mutated aquaporins exhibit moderate turgor pressure and are hypertonic. The correct option is d.

What are aquaporins?

Aquaporins are membrane channels that are found in practically every creature and are used to transport water and other tiny dissolved substances across cell membranes in both directions.

Osmoregulation and energy homeostasis depend on water and solute fluxes through epithelial and cell membranes. Aquaporins are typically present in the membranes of both plants and animals.

Aquaporins can facilitate the fast passage of carbon dioxide, and ammonia through the plasma membrane. Aquaporin expression is therefore crucial for a variety of animals.

Therefore, the correct option is d.

Fun Fact - Most Disney characters wear gloves to keep animation simple.

Walt Disney might have been the first to put gloves on his characters, as seen in 1929’s The Opry House starring Mickey Mouse. In addition to being easier to animate, there’s another reason Disney opted for gloves: “We didn’t want him to have mouse hands because he was supposed to be more human,” Disney told his biographer in 1957.

O Remote sensing satellite image of land use

Answers

The correct answer is E) Remote sensing satellite image of land use.

The statement that best describes the data presented in the image is "Remote sensing satellite image of land use."

This modern technique uses technology to assess the use of some portion of land and its physical characteristics

As we see in the picture of the map, using this remote sensing satellite image, specialists can see the use of the land, how the territory is used or occupied by people or by farming activities, or to assess the population density of the area.

In this case, we see the border of México and the United States, separated by the river, and the land on both sides of the border. We can see how the Mexican side is overpopulated, while on the United States side there are more open and rural areas that can be used for farming.

Scientists are closely monitoring caribou populations to examine the effect of global climate change on
habitat. The maximum population size for a herd of caribou based on the amount of habitat was 500,000. A
herd of caribou currently has a population size of 198,000 caribou as a result of habitat loss. Which of the
following methods should be used to determine the percent change between the maximum population and
the current population for this herd of caribou?

Answers

Answer: (198,000 caribou - 500,000 caribou) / 500,000 x 100

Explanation: makes sense for the math

The percentage difference allows testing the hypothesis. The decrease of 60.4% of the herd is due to the decrease of the habitat.

To test the scientists' hypothesis between the size of the caribou population and the size of the habitat, they must use a statistical method.

The percentage difference is a method that shows the difference between the current values ​​and some reference ones, it allows knowing the magnitude of the change between the two values, its expression is

            D% =[tex]\frac{measured \ value - reference \ value }{reference \ value } \ 100%[/tex]

Let's calculate

              D% = [tex]\frac{198000 - 500000 }{ 500000}[/tex]198000 - 500000/500000 100

              D% = -60.4%

The negative sign indicates decrease.

Therefore, the percentage difference allows the hypothesis to be tested. The decrease of 60.4% of the caribu is due to the decrease of the habitat.

as expressed in the excerpt?

The United States should increase domestic manufacturing to promote prosperity.
The farmers of the United States should switch to manufacturing jobs.
The sections of the United States should retain separate regional economies.

Answers

Answer:

The United States should increase domestic manufacturing to promote prosperity.

Explanation:

Excerpt:

“The creation of a home market is not only necessary to procure for our agriculture a just reward of its labors, but it is indispensable to obtain a supply of our necessary wants. . . . Suppose no actual abandonment of farming, but, what is most likely, a gradual and imperceptible employment of population in the business of manufacturing, instead of being compelled to resort to agriculture. . . . Is any part of our common country likely to be injured by a transfer of the theatre of [manufacturing] for our own consumption from Europe to America?

“. . . Suppose it were even true that Great Britain had abolished all restrictions upon trade, and allowed the freest introduction of the [products] of foreign labor, would that prove it unwise for us to adopt the protecting system? The object of protection is the establishment and perfection of the [manufacturing] arts. In England it, has accomplished its purpose, fulfilled its end. . . . The adoption of the restrictive system, on the part of the United States, by excluding the [products] of foreign labor, would extend the [purchasing] of American [products], unable, in the infancy and unprotected state of the arts, to sustain a competition with foreign fabrics. Let our arts breathe under the shade of protection; let them be perfected as they are in England, and [then] we shall be ready . . . to put aside protection, and enter upon the freest exchanges.”

Henry Clay, speaker of the House of Representatives, speech in Congress, 1824

      This "System" was made up of three interdependent components: a tariff to support and protect American industry; a national bank to promote trade; and government funding for infrastructure projects like roads, canals, and other "internal improvements" to create viable markets for agricultural products.

What is the short definition of the American system?

       The federal government's strategy for advancing industry in the United States through the implementation of a high protective tariff and the development of internal improvements.

      The American system under Henry Clay established a protective tariff, rechartered the national bank, and supported the growth of the country's transportation infrastructure. This system benefits the north more than the south because the protective tariffs shielded US industry from British competition.

     Which definition best encapsulates Henry Clay's American System? In order to help those in the North, taxes were imposed on goods from the South.

       In a speech he gave in 1824, Clay used the phrase "American System" for the first time. It was a government policy that was founded on the market economy. Specific goods would be produced in some parts of the nation and sold to others.

Explain each of the five theories of emotion (James-Lange, Cannon-Bard, Schachter-Singer two-factor theory, Zajonc and LeDoux, and Lazarus) discussed in the text.

Answers

Answer:

The James-Lang theory states that our experiences of emotion is our awareness of our physiological responses to emotion-arousing stimuli, meaning that your body does certain thing which is then followed by an emotion. For example, your heart racing, and body shaking would be followed by a sudden rush of fear. 

The Cannon-Bard theory states that an emotion arousing stimulus simultaneously triggers a physiological response and the subjective experience of an emotion. Disagreeing with the James-Lang theory, the Cannon-Bard suggests that the feeling of fear does not cause your heart rate to increase but your heart rate increasing, does not evoke a feeling of fear, rather, these are both separate occurrences that happen simultaneously.

The two-factor theory states that to experience emotion, you must be physically aroused and cognitively label the arousal. This means that in order to feel an emotion you have to be consciously aware of the stimuli provoking and causing the emotion. 

The Zajonc, LeDoux, and Lazarus theory states that some emotions can occur instantly with out conscious appraisal.
