Explain how pasteur's experiment supported the idea that cells only come from other cells. Explain how it failed to support the idea of spontaneous generation.
Answer:
Pasteur and Tyndall Louis Pasteur's 1859 experiment is widely seen as having settled the question of spontaneous generation. He boiled a meat broth in a swan neck flask. ... When the flask was turned so that particles could fall down the bends, the broth quickly became clouded.
Explanation:
State a technology and
explain how it is used to
forecast a future event.
I don't really know your question but I will tell you what can be predicted.
But how can a technological forecast be made to contain probability dimensions in the same way other forecasts do? Most people think of a technology as a quite specific physical entity. They do not conceive of this entity as having the variable characteristics which would permit range forecasts or probability statements. To their minds, a precisely defined technology either will exist in a given situation, or it will not. And the forecaster must predict this exact event or else he is wrong. This misconception—which would place an impossible demand on any forecaster causes much of the confusion in discussions about technological forecasting.

Which of the following describes erosion caused by glaciers?
It forms big ice chunks.
It changes the temperature.
It happens quickly.
It takes a long time.
Answer:
The 4th option.
Explanation:
Erosion from glaciers takes a long time because glaciers move very slowly across the land. For example, The Appalachian Mountains in the U.S. used to be really tall but slowly overtime, glaciers rounded them off.

weight and survive, he needs to intake 59 Kcal/kg of body weight per day.
This means he needs to consume 59 Kcal for every one kg of his body
weight.
How do we determine the number of Kcal per day for the fox?
Answer:
472kcal
Explanation:
You multiply the number of calories with the number of kilograms.
59*8=472kcal
Which process do all organisms do when performing cellular respiration?
Answer:
Glycolysis
Explanation:
Glycolysis is the first step of cellular respiration, where glucose is turned into 2 pyruvate molecules.
This step happens in all living organisms, since it does not require oxygen and also occurs in the cytoplasm, which all cells have.
So, glycolysis is the process that all organisms do during cellular respiration.

5. On vacation at a lake, Saira's mom sees an interesting-looking rock formation. Saira just learned
about rocks in geology class and tells her mom that the formation is made of gneiss, a type of
metamorphic rock. How did this metamorphic rock form?
Answer:it was heated and under pressure
Explanation:
Metamorphic rocks are formed from existing rocks, under high temperature and high pressure. This process is called metamorphism.
What is a metamorphic rock?Metamorphic rocks are those rocks that are formed from different kinds of rock like igneous, sedimentary, or gneiss rock under high pressure and intense temperature. They are rigid in nature.
In the formation of metamorphic rocks, firstly existing rock is broken down into small particles by physical, chemical, or biological agents. The process of breaking down rock is called weathering. Then erosion and transportation of these particles take place by the wind, water, or any biological agent.
The next step involves compaction after sedimentation. Thus, metamorphic rocks are formed from existing rocks.

polar
non-polar
Answer:
The nature of the indicated covalent bond is polar.
Explanation:
The given diagram is the Lewis structure of Methylamine which has the formula, CH₃NH₂.
In order to know that it is polar, we will discover that in the Lewis structure there are unpaired electrons in the central atom. Also, the bond that exists between the hydrogen and nitrogen shows that it is polar.
CH₃NH₂ is seen to have two charged ends that are opposite and the bonds that exists between hydrogen and nitrogen, which makes it a polar molecule.
The electronegativities of carbon, hydrogen and nitrogen can also be used to determine its polarity.

Identify the statement that is true about Charles Darwin's theory of evolution by natural selection. Choose one: A. In each new generation, those that survive and those that don't are determined randomly. B. Organisms that are able to survive and reproduce pass on characteristics to their offspring. C. Populations of organisms continuously increase over time. D. As environments change, individual organisms choose to change to better suit the new environment.
Answer: Option B.
Organisms that are able to survive and reproduce pass on characteristics to their offspring
Explanation:
Charles Darwin theory of natural selection states that organisms possesses heritable traits that they developed and are able to survive, reproduce and adapt to their environment and they pass those traits to their generations. It is a differential survival mechanism.organisms that are able to survive and reproduce pass on the heritable characteristics to their offsprings and produce more organisms.
The statement that is true about Charles Darwin's theory of evolution by natural selection is option "B" which is Organisms that are able to survive and reproduce pass on characteristics to their offspring.
What is Charles Darwin's theory of evolution?Charles Darwin's theory of evolution is also known as darwin's theory.
