what are three things that louis pasteur discovered about how yeast works?

Answers

Answer 1

Louis Pasteur made three significant discoveries about how yeast works: (1) Yeast is a living organism responsible for fermentation, (2) Fermentation is a biological process driven by yeast, and (3) Yeast can be influenced by factors such as temperature and oxygen availability.

Louis Pasteur's experiments and observations on yeast led to important discoveries about its role in fermentation. Firstly, Pasteur demonstrated that yeast is a living organism rather than a chemical catalyst. He showed that yeast cells are responsible for the conversion of sugar into alcohol and carbon dioxide during fermentation, debunking the long-held belief that fermentation was a purely chemical process.

Secondly, Pasteur established that fermentation is a biological process driven by yeast. He observed that fermentation only occurred when yeast cells were present in the fermenting medium, and he demonstrated that heat-sterilized grape juice remained non-alcoholic until introduced with live yeast.

Lastly, Pasteur discovered that yeast can be influenced by environmental factors. He found that the rate of fermentation and the quality of the resulting product could be affected by factors such as temperature and oxygen availability. Pasteur's studies on yeast paved the way for the development of better fermentation techniques and understanding of microbial processes, contributing to advancements in various fields, including brewing, winemaking, and biotechnology.

Which of the following is an example of active transport?
A facilitated diffusion
B osmosis
C diffusion
D endocytosis

Answers

The correct option is D - Endocytosis is an example of active transport.

Active transport is a type of cellular transport that moves molecules or ions across a cell membrane against their concentration gradient, which means from low concentration to high concentration. The process requires energy in the form of ATP (adenosine triphosphate) and carrier proteins.

Endocytosis is a process of active transport in which a cell engulfs particles by invaginating its membrane to form a vacuole. It is the movement of large particles or substances into the cell and occurs through a variety of mechanisms such as phagocytosis, pinocytosis, and receptor-mediated endocytosis.

Facilitated diffusion is a type of passive transport, which means it moves molecules or ions across a cell membrane from high concentration to low concentration, without the input of ATP. This process requires a carrier protein to help molecules or ions pass through the membrane.

Osmosis is also a type of passive transport that moves water across a membrane from high to low concentration. It does not require any ATP energy, but it does require a membrane to be present.

Diffusion is the movement of molecules or ions from an area of high concentration to an area of low concentration. This process can happen without the input of ATP energy, and it does not require a membrane.

Endocytosis is an example of active transport that moves molecules or ions across a cell membrane against their concentration gradient, which requires energy in the form of ATP and carrier proteins. Therefore, option D is correct.

Which of he following factors in considered teh greatest threat to biodiversity today? a. Habitat destruction and fragmentation b. invasive species c. Overexploitation d. Pollution

Answers

Habitat destruction and fragmentation are considered the greatest threat to biodiversity today.

Habitat destruction and fragmentation have significant impacts on biodiversity and are recognized as the primary threat to the survival of many species. Human activities, such as deforestation, urbanization, and land conversion for agriculture, result in the destruction and fragmentation of natural habitats. These actions lead to the loss of critical habitats, disruption of ecological processes, and isolation of populations, ultimately reducing species diversity.

Habitat destruction destroys the homes and resources that species depend on for survival, pushing them towards extinction. Fragmentation further exacerbates the problem by dividing habitats into smaller, isolated patches, limiting the movement and gene flow of species. This fragmentation can lead to reduced genetic diversity, increased vulnerability to environmental changes, and reduced population sizes, making species more susceptible to extinction.

While invasive species, overexploitation, and pollution also pose significant threats to biodiversity, habitat destruction and fragmentation have far-reaching and long-lasting consequences, affecting ecosystems on a global scale. Protecting and restoring habitats, implementing sustainable land-use practices, and promoting conservation efforts are crucial for mitigating the loss of biodiversity caused by habitat destruction and fragmentation.

what polysaccharide is the form of short term energy storage in animals?

Answers

The form of short-term energy storage in animals is glycogen.

Glycogen is a polysaccharide that serves as the primary form of short-term energy storage in animals. It is a highly branched polymer composed of glucose molecules linked together. Animals store glycogen primarily in the liver and muscles, where it can be readily accessed when energy is needed.

Glycogen functions as a reservoir of glucose units that can be quickly broken down through a process called glycogenolysis. When blood glucose levels drop, hormones such as glucagon signal the breakdown of glycogen into glucose, which can be released into the bloodstream to maintain stable blood sugar levels. This process is especially crucial during periods of fasting or increased energy demands.

Additionally, glycogen synthesis occurs when glucose levels are high, primarily stimulated by the hormone insulin. Excess glucose is converted into glycogen and stored for future energy needs. Glycogen provides a rapid and accessible source of glucose for energy production, allowing animals to maintain essential metabolic functions and sustain physical activity between meals.

why would it be important to replicate dna before a cell divides in mitosis

Answers

DNA replication before cell division in mitosis is important to ensure that each daughter cell receives an identical copy of the genetic information.

DNA replication is a crucial process that occurs before cell division in mitosis. During replication, the DNA molecule unwinds and separates into two strands, each serving as a template for the synthesis of a new complementary strand. This process results in the formation of two identical copies of the original DNA molecule. The importance of DNA replication lies in the need for each daughter cell to receive an exact replica of the genetic information present in the parent cell. This ensures that the genetic material is accurately transmitted to the next generation of cells, allowing for proper growth, development, and maintenance of the organism. Without DNA replication, errors or alterations in the genetic code could occur, leading to potentially harmful consequences.

Question 61 1 points Which of the following statements best describes the true nature of natural selection? o Only the strongest survive. The strong eliminate the weak in the race for survival. Organisms change by random chance. Heritable traits that promote reproduction become more frequent in a population from one generation to the next.

Answers

The true nature of natural selection is that heritable traits that promote reproduction become more frequent in a population from one generation to the next.

Natural selection is a fundamental mechanism of evolution that drives changes in populations over time. It is not about the survival of the strongest or the elimination of the weak, nor is it based on random chance. The essence of natural selection lies in the differential reproductive success of individuals with certain heritable traits.

In every population, there is variation in traits among individuals due to genetic differences. Some of these traits may confer advantages in terms of survival, reproduction, or both. When individuals with these advantageous traits have a higher probability of surviving and producing offspring, those traits are more likely to be passed on to the next generation. Over time, this leads to an increase in the frequency of these beneficial traits in the population.

The key concept is that natural selection acts on heritable traits, meaning traits that can be passed down from parents to their offspring. Traits that enhance an organism's ability to survive, find mates, obtain resources, or successfully reproduce tend to become more common in subsequent generations. This process of selective reproduction gradually shapes the characteristics of populations, leading to adaptations that are better suited to the environment and increasing the overall fitness of the population.

the first step toward generating a skeletal muscle contraction is:

Answers

The first step toward generating a skeletal muscle contraction is the arrival of a nerve impulse at the neuromuscular junction.

When a nerve impulse reaches the neuromuscular junction, it triggers the release of a neurotransmitter called acetylcholine. Acetylcholine then binds to receptors on the muscle fiber's membrane, initiating a series of events that lead to muscle contraction. This binding of acetylcholine causes the depolarization of the muscle fiber's membrane, resulting in the generation of an action potential. The action potential propagates along the muscle fiber, leading to the release of calcium ions from the sarcoplasmic reticulum. Calcium ions then bind to regulatory proteins, initiating the contraction process by allowing myosin heads to interact with actin filaments. This interaction generates the sliding of actin and myosin filaments, resulting in muscle contraction.

figure 1 is an electron microscope showing a cross section through a neurone.
the myelin sheath of this neurone is 250mm in thickness.

calculate the magnification of this electron micrograph.
*measured to be 5mm

Answers

To calculate the magnification of the electron micrograph, we can use the formula:

Magnification = Image size / Actual size

Given:
Image size = 5 mm
Actual size of the myelin sheath = 250 μm (since 1 mm = 1000 μm)

First, we need to convert the actual size from micrometers to millimeters by dividing it by 1000:

Actual size = 250 μm / 1000 = 0.25 mm

Now we can calculate the magnification:

Magnification = 5 mm / 0.25 mm = 20

Therefore, the magnification of this electron micrograph is 20.
Final answer:

The magnification of the electron micrograph is calculated by dividing the observed size (5mm) by the actual size (250mm) of the neurone's myelin sheath. Therefore, the magnification is 0.02, indicating the real image is enlarged 2% of its original size in the micrograph.

Explanation:

To calculate the magnification of the electron micrograph, we need to divide the size of the image (observed size) by the actual size of the image (real size). It is given that the myelin sheath of the neurone in the image measures 5mm (observed size), while the actual size is 250mm.

Therefore, the magnification can be calculated as follows:

Magnification = observed size/actual size = 5mm/250mm = 0.02
