What substances move up in translocation? Select all that apply. water dissolved minerals sugar starch organic molecules
Answer:
organic molecules
Explanation:
Translocation refers to mobility, that is, the transport of organic substances produced in photosynthesis, from the leaves to other plant organs, by the phloem.
On the sheet, organic substances can have two export routes to other organs:
Apoplast pathway - corresponds to approximately 5% of the leaf volume, depending on the plant species; Simplast route - from cell to cell, through the cytoplasm.The transport out of the leaf occurs when the solutes, after crossing the mesophile, enter the apoplast and are transferred to the phloem and, afterwards, out of the leaf. Some are transported quickly, such as nitrogen and phosphorus, while others such as calcium and boron, may be partially mobile or immobile.
Earth's atmosphere blocks much of the light that astronomers need to observe distant stars. To get around this problem, NASA put a powerful telescope A) on Mars. B) on the Moon. C) in orbit around Earth. D) in orbit around the Moon.
The answer is; C
By putting the Hubble telescope in orbit around the earth, they avoid most of the earth’s dense atmosphere. The atmosphere causes a phenomenon referred to as atmospheric differential diffraction of light that is the reason we see stars as twinkling (yet they really don't twinkle). Avoiding atmosphere, therefore, improves image quality, reduces mirages, and reduces errors in observation.

Explanation:
A cell is in a equilibrium with its surrounding at 30 degrees Celsius. The molarity of surrounding sucrose solution is 0.5m. Calculate the solute potential of the surrounding solution
Solute potential of a solution is calculated using the formula,
Ψ[tex]_{s}=-(iCRT)[/tex]
Where,
Ψ[tex]_{s}[/tex]is the solute potential of the solution,
i is the degree to which the solute ionizes(ionization constant) in solution = 1, as sucrose is a nonelectrolyte.
C is the concentration of the solution in molarity = 0.5 M
R is the gas constant or the pressure constant = 0.0831 L.bar/(mol.K)
T is the temperature in Kelvin scale = [tex]30^{0}+273 =303 K[/tex]
Calculating the solute potential of the surrounding sucrose solution:
Ψ[tex]_{s}=-(iCRT)[/tex]
= -(1 * 0.5 M * (0.0831 L.bar/(mol.K))* 303 K)
= 12.6 bar
Therefore, the solute potential of the surrounding solution is 12.6 bar
The solute potential of the surrounding sucrose solution can be calculated using the formula Ψs = -iCRT, where i is the ionization constant, C is the molar concentration of the solute, R is the pressure constant, and T is the temperature in Kelvin. The solute potential of the given solution is approximately -12.4879 bar.
Explanation:Solute potential (also known as osmotic potential) is a measure of the tendency of water to move from a solution of low solute concentration to a solution of high solute concentration. The formula for calculating solute potential is Ψs = -iCRT, where i is the ionization constant, C is the molar concentration of the solute, R is the pressure constant, and T is the temperature in Kelvin.
In this case, the molarity of the surrounding sucrose solution is given as 0.5M. We need to convert the temperature from Celsius to Kelvin by adding 273 to 30, giving us 303K. The ionization constant for sucrose is 1 because it does not ionize. The pressure constant (R) is typically given as 0.0831 liter bar/mole K.
Plugging in the values into the formula, we get Ψs = -1 * (0.5M) * (0.0831 liter bar/mole K) * (303K).
Simplifying the equation, we find that the solute potential of the surrounding sucrose solution is -12.4879 bar.

Who is most in danger from the effects of overfishing ?
I don't think we can answer this question just like that. The question should be formulated a bit differently:
WHAT is in danger from the effects of overfishing?
Well, in the end of the "effect-spectrum" we are in danger, since we also eat fish. But the most affected species are the ones that form the aquatic ecosystems. Such as fish. Examples:
1 - Many of the fish we eat, feed on sea-weed. If there aren't enough fish to eat the growing population of sea-weed, many fish die of intoxication.
2 - We don't have almost any fish restrictions in a way, because we can eat basically all of them. Therefore, many fish (which are also being eaten) find themselves in a lack of food.
3 - Many times, we concentrate on a specific species, which is a main cause of the extinction of species.
Hope it helped,
BioTeacher101
Those most at risk from overfishing include marine ecosystems, species threatened by extinction, human populations reliant on marine resources for sustenance and economic activities, and species caught as bycatch. The depletion of certain species disrupts the ocean's ecological balance, which can lead to broader environmental and economic repercussions.
Those most in danger from the effects of overfishing are the marine ecosystems and the human populations that rely on them for food and economic stability. Overfishing causes the depletion of fish populations which can result in species extinction and disrupts the ocean food chain. This can lead to ecological imbalance, affecting not just the targeted fish species but also non-target species that become bycatch. The Food and Agriculture Association has estimated that many fish species are either fully exploited or depleted, impacting food security for millions who depend on these resources for animal protein. Overfishing also contributes to economic losses in the fishing industry and threatens the livelihoods of coastal communities.
Specifically, the overharvesting of menhaden can have significant implications. Menhaden serve as forage fish within food webs, supporting larger fish, marine mammals, and seabirds. Overharvesting menhaden can thus harm top predators and disrupt maritime economic activities. Furthermore, bycatch contributes significantly to the mortality of various marine species, including marine turtles and seabirds, leading to further ecological consequences.

What happens when someone orders a second dessert when he or she is already full from the first dessert?
Answer:
The second dessert has less utility than the first dessert.
Explanation:
After lunch or dinner, the desire to eat dessert grows because heavier foods are slow to be processed, and the body is still hungry. So the first dessert has the effect of quenching a person's hunger. So after eating dessert the body feels satisfied and not hungry. However, when this person asks for a second dessert, the body is already satiated, so the second dessert will not be as useful as the first.
Answer:
The second dessert has less utility than the first dessert.

What is the correct term for organisms that convert gaseous nitrogen into other nitrogen compounds that other organisms can use to produce organic material? Organisms such as some cyanobacteria convert gaseous nitrogen into other nitrogen compounds that other organisms can use to produce organic material. They are referred to as .
Answer: Nitrogen fixing agent
Nitrogen fixation is a biological process that converts atmospheric nitrogen into another forms of nitrogen used by plants and other organisms. Nitrogen fixation is carried out by organism referred as nitrogen fixing agents. The group of nitrogen fixing agent mainly includes many species of bacteria such as cynobacteria. These bacteria lives in symbiotic association with plants. These bacteria have the nitrogenase enzyme that makes a combination of atmospheric nitrogen with hydrogen to produce ammonia, which is further converted into other organic compounds. These organic compounds are necessary for amino acid synthesis in plants , which further helps in synthesis of proteins. These proteins are necessary for growth of plants. In return these bacteria receive nutrition from the plants through roots.
Final answer:
Nitrogen-fixing organisms convert atmospheric nitrogen into usable nitrogen compounds. Cyanobacteria and certain bacteria and archaea are examples, with cyanobacteria using specialized heterocyst cells for the process.
Explanation:
The correct term for organisms that convert gaseous nitrogen into other nitrogen compounds usable by organisms to produce organic material is nitrogen-fixing organisms. These organisms include certain bacteria and archaea, which can fix nitrogen from the atmosphere independently. However, many nitrogen-fixing microorganisms live in a symbiotic relationship with plants, such as Rhizobium species that dwell in root nodules of legumes and free-living bacteria like cyanobacteria. Cyanobacteria are noteworthy as they form specialized cells called heterocysts to fix nitrogen anaerobically, due to the oxygen they produce in photosynthesis, which could otherwise inhibit the nitrogenase enzyme required for nitrogen fixation.

How are their lifestyle (Mayan) and the roles of men and women similar and different from life in our culture?
The Maya has been inhabited in much of Central America, now known as Guatemala, Belize, Honduras, El Salvador and five southern states of Mexico such as Campeche, Chiapas, Quintana Roo, Tabasco and Yucatan. Founded in the pre-classical period (about 2000 BC to 250 AD), according to the chronology of Central America, many Mayan cities reached their highest level of development during the classical period (approximately 250 m to 900 m) and continued beyond Classic until the arrival of Spaniards. They had a civilization that dates back about 3000 years. During that long time, hundreds of dialects were spoken in these lands, from which about 44 different Maya languages were born. It was known as the only civilization in the development of the written language in the pre-Columbian Americas, as well as art, architecture, and mathematics and astronomy systems.
The talk of the ancient Maya refers to the history of one of the most important cultures of Central America in pre-Columbian times, because it has a world-renowned scientific and astronomical heritage. Their civilization has contributed many advantages to other civilizations in Central America because of the great interaction and dissemination of the culture that characterized the region. Progress, such as writing, engraving, and calendaring with the Mayans, has not only arisen but has been fully developed. The influence of that civilization can be detected in Honduras, Belize, Guatemala and Western El Salvador as far away as central Mexico, more than 1,000 km (620 miles) from the Mayan region. Architectural and artistic traces of the Maya were found outside the area and are believed to be due to trade and cultural exchange.
The Mayan people did not disappear completely at the time of the decline of the classical period or with the arrival of the Spanish invasion and colonization of the Americas, where the Mayans are now the majority of the inhabitants of all Mayan areas and have maintained the distinctive traditions and beliefs that are the result of the fusion of ideas and cultures for pre-Columbian and post- Invasion. At present millions of people speak different Maya languages.
The Mayan literature illustrates the life of this culture. Examples include the play "Raphael Atchi" written in the language of Atchi, which was announced by UNESCO in 2005 as a masterpiece of the intangible oral heritage of mankind, and of the literary works of Popul Fuh for historical legends. . What was destroyed by the Spanish invasion is a model of the pre-Columbian civilization that is estimated at 3,000 years of ancient history.
