What was shown by both Redi’s and Pasteur’s experiments?
Answer:
Their experiment showed that the flies did not come directly from meat but flies laid their eggs there (disprove the spontaneous generation).
Explanation:
Redi put meat in three different jars one jar with covering and another without covering and the 3rd jar was sealed. He disproved spontaneous generation theory in this experiment. He showed that maggots did not come directly to meat but came from eggs laid by flies The sealed jar had no maggots in the meat.
Pasteur also checks the spontaneous generation theory by putting the boiling broth in different flasks, some open and some sealed. The conclusion he drew from this is that living things did not come from broth directly.
Thus, their experiment showed that the flies did not come directly from meat but flies laid their eggs there (disprove the spontaneous generation).
Through aquatic succession, a clear lake may eventually become
Meadow
Through aquatic succession, a clear lake may eventually become meadow.
Explanation;Aquatic succession refers to the process by which a glacial lake dries up. Aquatic succession takes place as a result of disturbances which results in aquatic area filling with sediment or organic matter.During aquatic succession a series of stages that causes bodies of water to turn into simply land. The process of aquatic succession is also called hydrosere and hydrarch succession.Meadow is a field that is habited by grass and other non-woody plants.Through aquatic succession, a clear lake may eventually become a marsh or a forested wetland.
Aquatic succession is a water body's steady ecological community and habitat change. A clean lake can change ecosystems over several succession stages.
Clear Water Stage: Early lakes have clear, nutrient-poor water. Algae and submerged aquatic plants are the principal producers.Emergent Plant Stage: As sediment and organic matter collect in the lake, reeds, cattails, and bulrushes can grow. These plants have sediment roots and water-surface stems.Shrub and Scrub Stage: As the lake fills with sediment, emerging plants establish habitats for willows and dogwoods. These plants can survive periodic flooding and grow near lakes.Water chemistry, nutrient availability, and sediment deposition cause this progression from a clear lake to a marsh or wooded wetland. Adapting to shifting conditions, the new ecosystem supports a varied range of plants and animals.

A.The growth pattern will change from logistic to exponential.
B.The minimal viable population for the deer will increase.
C.Deer from other populations will immigrate to find mates to reproduce successfully.
D.The population will remain healthy, and its numbers will increase.
The population size will drop until the numbers reach the carrying capacity.
Answer: E. The population size will drop until the numbers reach the carrying capacity.
A carrying capacity of the ecosystem is the number of individuals in the population of species a ecosystem can sustain on the basis of availability of resources (food, shelter). Conservationists established that the carrying capacity of a population of deer in an extensive geographical area is 945 which increased to 1,100. This sudden increase in the population of deer, will result in depletion of resources, hence, carrying capacity of the ecosystem cannot sustain increased members of the population. Therefore, the population size will drop until the numbers reach the carrying capacity.
In Mendel's experiment with round- and wrinkled-seed plants, the F1 plants, which produced only round seeds, were grown up andmatured and were allowed to self-fertilize. What was the ratio of round to wrinkled seeds in the F2 generation?
The ratio of round to wrinkled seeds in Mendel's experiment was 3:1 in the F2 generation.
Explanation:In Mendel's experiment, when the F1 plants, which produced only round seeds, were allowed to self-fertilize, the ratio of round to wrinkled seeds in the F2 generation was 3:1.
This means that in a large population of F2 offspring chosen at random, approximately 75 percent would be expected to have round seeds, while 25 percent would be expected to have wrinkled seeds.
This ratio demonstrates Mendel's observation of the dominant and recessive traits in his experiment.

Special senses, such as sight and sound, are detected by:
"The correct answer is: Special senses, such as sight and sound, are detected by sensory receptors.
Sensory receptors are specialized cells or structures that respond to specific types of stimuli in the environment. These receptors are the first step in the process of sensory perception. For example, photoreceptor cells in the retina of the eye detect light, while hair cells in the inner ear detect sound vibrations. These sensory receptors convert the stimuli into electrical signals that are then transmitted to the brain via sensory neurons. The brain interprets these signals, allowing us to experience sensations such as sight and sound. The process by which sensory receptors convert stimuli into electrical signals is known as sensory transduction. Each type of sensory receptor is tuned to specific types of physical or chemical stimuli, ensuring that the nervous system can accurately detect and respond to changes in the internal and external environment."

If DNA can’t leave the nucleus, how dose the DNA instructions get to the ribosomes in the cytoplasm
DNA instructions are conveyed to the cytoplasmic ribosomes by mRNA, which is synthesized in the nucleus through transcription. mRNA then exits the nucleus to enable protein synthesis by the ribosomes. This process is essential to the central dogma of molecular biology.
Explanation:The genetic instructions housed within DNA in the nucleus are transferred to the ribosomes in the cytoplasm through the process of transcription and translation. During transcription, an intermediate molecule called messenger RNA (mRNA) is synthesized based on the DNA template. This mRNA molecule is small enough to travel through the nuclear pores into the cytoplasm where ribosomes read its sequence to synthesize proteins.
The nucleolus is responsible for the synthesis of ribosomal RNA (rRNA), which is then assembled with proteins to form the subunits of ribosomes. These subunits exit the nucleus to participate in protein synthesis in the cytoplasm.
Overall, the flow of genetic information in a eukaryotic cell goes from DNA to RNA (specifically mRNA) and finally to protein, abiding by the central dogma of molecular biology.

Explain how to frequency of sound changes as an ambulance approaches you and passes you by as you stand on a sidewalk.
The Doppler effect is observed when the source of a particular set of waves is moving with respect to the observer. Suppose you are standing on the sidewalk, waiting to cross the street. On the far left side of your position, you see an ambulance racing in your direction. In this case, the siren on the ambulance is the source of the waves (sound waves, in this case) and you are the observer.
Apparent Increase in Wave FrequencyAs the ambulance approaches you, the distance between the source of the waves and the observer decreases. Consequently, the siren sounds more shrill as the pitch of the wailing siren ‘sounds’ higher than its original value, as sound waves reach you ‘more frequently’. It should be noted that there is absolutely no difference between the frequency of the original sound waves and the sound waves approaching you; you simply perceive the sound to be higher pitched as the sound waves reach you at a more frequent rate, because the distance between you and the ambulance is closing.
Answer:
As the ambulance approaches you, the distance between the source of the waves and the observer decreases. Consequently, the siren sounds more shrill as the pitch of the wailing siren 'sounds' higher than its original value, as sound waves reach you 'more frequently'.

How does carbon move between the atmosphere, hydrosphere, biosphere, and geosphere?
Answer:
Carbon is an element and is part of the oceans, air, rocks, soils and living things, it does not stay in one place.
In the atmosphere, it combines with oxygen in a gas called carbon dioxide (CO2). With the help of the sun, through photosynthesis, carbon dioxide is extracted from the air and converted into food.
Through food chains, carbon from plants goes to the animals that feed on them. Animals that eat other animals also obtain carbon through their food.
When plants and animals die, their bodies, wood, and leaves decompose in the soil. Part of the decomposed matter is buried and after millions and millions of years, it becomes fossil fuel.
Each time you breathe out, carbon dioxide is released into the atmosphere. Animals and plants get rid of the gas through the process known as respiration.
The carbon from fossil fuels goes into the atmosphere when the fuel is burned. When humans burn fossil fuels to power their factories, power plants, cars, and trucks, most of the carbon quickly enters the atmosphere in the form of carbon dioxide gas. Every year, five and a half billion tons of carbon are released in the form of fossil fuels burned. Of the large amount of carbon released by fuels, only 3.3 billion tons penetrate the atmosphere, and most of the rest is dissolved in the seawater.
The oceans and other bodies of water absorb some of the carbon from the atmosphere. It dissolves in water. Marine animals use carbon to create the material for their skeletons and shells.
Carbon dioxide is a greenhouse gas that traps heat in the atmosphere. When carbon is deposited on the seabed, it is stored outside the carbon cycle for long periods of time. The amount of limestone deposited in the ocean depends in some way on the amount of shallow, tropical and warm oceans on the planet, because that is where limestone-producing organisms, such as corals, proliferate. Carbon can be released back into the atmosphere if the limestone melts or undergoes metamorphosis in a subduction zone.
