Fermentation is a chemical reaction that occurs in the cytoplasm . Because it is Choose... , fermentation Choose... oxygen. Compared to cellular respiration, lactic acid fermentation generates Choose... ATP and is less efficient.
Answer:
Fermentation is a chemical process that occurs in the cytoplasm since it is anaerobic, that is, with the absence of oxygen.
Explanation:
This anaerobic process is due to the consumption of carbohydrates in the absence of oxygen compared to intense muscular demands such as high-performance physical activity, that is why the obtaining of energy is high, since the purpose is not to anabolize but to catalyze hydrates in order to obtain the energy currency that is ATP and thus produce the contraction of the muscular sarcomero by the union of myosin with actin.

(Environmental) Southern England What are the major concerns about soil erosion on arable land in Britain?
Answer:
Soil nutrient loss
Algae blooms
Pollution of water ways
Explanation:
Soil nutrient loss - a major concern as when soil erodes, this results in nutrient run off. Heavy rains can "wash away" essential nutrients within the soil therefore reducing the fertility of the land.
Algae blooms - when nutrients run off soil as a result of soil erosion they can leech into nearby fresh stream and even into salt water marine environments. This large increase of nutrients results in algae thriving and forming a layer across the top of the water. This reduces the oxygen and sunlight available to other marine plants and essentially suffocates plant and animal species.
Pollution of water ways - The sediment of soil that is eroded makes its way into fresh water ways can not only "bury" plant species and reduce biodiversity but it also reduces the water quality. It can introduce pathogens to the water from liverstock farming as well as introducing pesticides that may be harmful to wildlife.
regarding the population debate, the neo-malthusian thesis is often referred to as
a. malthusian
b. boserupian
c. cassandra
d. cornicopian
The neo-Malthusian thesis is a belief that the world's population will eventually outgrow the planet's resources, leading to starvation, poverty, and environmental degradation. It is named after Thomas Malthus, an economist who famously predicted in the late 1700s that population growth would outstrip food production.
The other options listed - boserupian, cassandra, and cornucopian - are all related to the population debate but represent different perspectives. The Boserupian thesis suggests that population growth will lead to technological innovation and increased agricultural productivity, while the Cassandra perspective warns of catastrophic consequences of overpopulation. The Cornucopian viewpoint holds that human ingenuity and resourcefulness will enable us to overcome any environmental or resource challenges posed by population growth.
The term "Cassandra" comes from Greek mythology, where Cassandra was a prophetess who was cursed to speak the truth but never be believed. In the context of the population debate, the Neo-Malthusian thesis (Cassandra) predicts that population growth will outpace resources, leading to negative consequences such as famine and poverty.

Without land regulations to protect rainforests, land continues to be destroyed using slash and burn methods. Which global need is increasing the rates of rainforest deforestation?
Local farmers need for new land
Global demand for natural gas
Country's demand for precious metals
Demand for palm oil from other countries
Answer: Local farmers need for new land
Explanation Forests are cut down to clear land for agriculture, livestock grazing, and settlement; for timber; to produce charcoal; and to establish tree plantations.
Deforestation occurs across all forest types, but is concentrated in the tropics and boreal regions. Temperate regions are experiencing a net increase in forest cover due to natural regeneration.
While deforestation produces food, fiber, and fuel, it can also pose risks to climate, biodiversity, and food security by degrading the ecosystem services normally afforded by healthy and productive forests.
The global need that is increasing the rates of rainforest deforestation is demand for natural gas. The correct option is B.
What is natural gas?Natural gas is a naturally occurring mixture of gaseous hydrocarbons, primarily methane, with minor amounts of other higher alkanes.
Low levels of trace gases such as carbon dioxide, nitrogen, hydrogen sulfide, and helium are also commonly present.
Natural gas is formed naturally over hundreds of millions of years. Layers of decomposing plants and animals are subjected to intense heat from the Earth and pressure from rocks to form it.
Land continues to be destroyed using slash and burn methods in the absence of land regulations to protect rainforests. The global demand for natural gas is driving up rates of rainforest deforestation.
Thus, the correct option is B.

Why in a habitate, there are usually more producers than harbivores, and more harbivores than carnivores?
In a habitat, there are usually more producers than herbivores and more herbivores than carnivores. This is due to the fact that energy is lost at each trophic level, making it more efficient for fewer organisms to occupy the higher levels.
The number of individuals at each trophic level decreases as you move up the food chain in a food web. Each trophic level can only extract about 10% of the energy from the level below it, making it more efficient to have fewer individuals at higher levels. As a result, producers are usually more numerous than herbivores, and herbivores are usually more numerous than carnivores.
Producers are the basis of the food chain in most ecosystems, and because energy is lost as it moves up the chain, it is more efficient to have fewer organisms at higher trophic levels. As a result, producers are more abundant than herbivores, and herbivores are more abundant than carnivores.

48. In the urea cycle, the SECOND nitrogen of urea originates form which of the following metabolites? a. alanine c. glutamine b. aspartate d. arginine 49. A person with phenylketonuria cannot convert
Option A: In the urea cycle, the second nitrogen of urea originates from alanine.
Option A: Phenylketonuria prevents the conversion of phenylalanine to tyrosine.
The aspartate and glutamate breakdown of amino acids provides the first nitrogen for urea in the urea cycle. The second nitrogen in urea, though, comes from alanine. A source of the second nitrogen atom required for the formation of urea, alanine is an amino acid that can be transformed to pyruvate and subsequently enter the urea cycle.
Phenylalanine is a crucial amino acid which needs to be converted into tyrosine. This conversion is brought in by an enzyme called phenylalanine hydroxylase. Lack of this enzyme results in the genetic disorder known as phenylketonuria (PKU). Tyrosine deficiency and phenylalanine accumulation are symptoms of PKU. This imbalance can have detrimental effects on brain development and function if not properly managed through dietary restrictions.

During cellular respiration, four total atp are produced when pyruvic acid is created. What else is produced as a result of this reaction?.
Heat is also produced as a result of this reaction.
The process by which glucose is broken down to provide energy is known as glycolysis. It generates two pyruvate molecules, ATP, NADH, and water. There is no need for oxygen throughout the process, which occurs in the cytoplasm of a cell. Both aerobic and anaerobic creatures experience it.
Four ATP molecules (net = 2) are produced during glycolysis in addition to the pyruvic acid that is created.
However, glycolysis releases energy in the form of heat, much like all other catabolic reactions that involve the breakdown of big molecules.
Therefore, heat is also produced as a result of glycolytic reaction (cellular respiration).

Pasteur used swan-neck flasks in his experiments to test the validity of spontaneous generation. Suppose that after allowing the flasks to sit for a day, he had tilted one of these flasks so that the sterile broth entered the swan neck. Suppose he had then tilted the flask back to allow the broth to settle back into the round bowl of the flask before leaving it to sit undisturbed for another few days. What would have happened, and how would these results have affected conclusions about spontaneous generation?
Answer:
See the answer below
Explanation:
If Pasteur had tilted one of the flasks so that sterile broth entered the swan neck and then tilted it back to allow the broth to settle back, that particular flask would have had microbes growing in it after being left undisturbed for a few days.
Allowing the sterile broth to get to the neck of the swan would lead to the contamination of the broth because the swan neck is not sterile. If this had happened, the observation of growth of microbes in one of the flasks would have given further credence to spontaneous generation.
Which of the following statements is true concerning a Youthful River:

b. Area erosion is primarily caused by the river downcutting into the bedrock below.
C. Erosional forces cause meander curves to develop in surrounding bedrock.
d. Deposition is greater than erosion in Young Rivers.
The correct statement is A. Area erosion is primarily caused by lateral, side-to-side, water movement.
More about the Youthful RiverAlso known as Young rivers are ones whose erosion is still in its early phases. The amount of lateral, side-to-side, water movement during this time causes the river to meander and erode the banks on both sides. Oxbow lakes are produced when a meander is severed from the main river channel due to erosion of the banks.
Young rivers are characterized by high energy, causing rapid erosion of the bed and banks. This erosion is caused by the lateral movement of the water, which creates meandering curves in the river. As the river erodes, it deepens, forming a valley. The river also carries sediment which is deposited in areas of slower water flow.
