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.

Based on the video, do you think changes to the environment could still affect living things on Earth today? Explain your answer using information from the video to support your argument.
Answer:
I didn't see the video but global warming might be one.
Explanation:
Due to global warming the polar ice caps are melting, so that means a decrease in the food a polar bear might have.
Answer:
An ice age caused Earth’s oceans to cool, which killed many of the unicellular organisms. When the ice age ended and Earth warmed, the continents broke apart. This event allowed the shallow seas to cover the continents. The warming of Earth, accompanied by the seas covering the land, created the proper conditions for multicellular organisms to form.

Diabetes is often suspected when glucose shows up in urine tests. Use the model to explain how glucose could be present in urine. Why do you think this symptom is especially concerning for young people?
Answer:
S.A for Edmentum and Plato
Like and Rate
In step 1, blood goes to the kidney for filtration. If excess sugar exists in the blood, the filtered substances will have more sugar than they do in a person who doesn’t have diabetes. In step 2, there is some reabsorption of sugar. But if there’s an unusually high amount to filter, some sugar will stay in the urine as it passes through the renal tubule to be excreted by the body. This symptom is concerning because it could stress the kidney, which could lead to kidney problems at a young age.

Answer:
In an oceanic environment the photic zone is the zone where light can be received it's usually from 0 to 200 m deep but this depth can be modified by the turbidity of the water. The aphotic zone is the zone where no light is receives it goes from 200 to the bottom of the sea.

Why does PE = mgh equal PE = Fw h ?
Answer:
Why is potential energy MGH?
Potential energy is energy an object has because of its position relative to some other object. ... For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.

True or False. More force is needed to move an object if you move the fulcrum closer to the load?
1. False
2. True
Answer:
false
Explanation:
if the fulcrum is closer to the load, it is esier and requires less force.
Answer:false
Explanation:A lever is a simple machine that is used to lift or move heavy loads by use of relatively smaller forces. It uses a fixed support or hinge known as a fulcrum.

How does a calorie on a food label relate to a calorie that is produced in cellular respiration?? Please help
Answer:
There are 1000 calories in 1 Calorie (notice the difference in the capital C) on our food labels the Calories are given. Cellular respiration ; the process that releases energy by breaking down glucose and other food molecules in the presence of oxygen, begins with a chemical pathway called glycolysis
Explanation:
Hope this helped, Have an amazing, spooky Halloween!!
The relationship between the calorie on a food label with the calorie produced in a cellular respiration is ;
I Calorie on a food label is equivalent to 1000 calories produced in cellular respirationWhen labeling food to indicate the nutrients contained in the food ( especially canned foods ) the amount of calories contained in the food is indicated and for every Calorie ( 1 calorie ) indicated on the label represents an equivalent of 1000 calories found in cellular respiration.
Hence we can conclude that 1 Calorie indicated on a food label is an equivalent of 1000 calories produced in a cellular respiration.

A population of 20 monarch butterfly is colonize a meadow. The meadows carrying capacity for a monarch butterfly's is 5000 individuals. What statement best describes the growth rate of the population of Monarch butterfly after the Meadow is colonized?
Answer:
D
Explanation:
A.
The population grows exponentially until it approaches 5,000 individuals, and then the population size begins to decrease.
B.
The population grows exponentially until it approaches 5,000 individuals, and then its growth rate decreases.
C.
The population grows at a constant rate until it approaches 5,000 individuals, and then its growth rate increases.
D.
The population grows at a constant rate until it approaches 5,000 individuals, and then the population size remains stable.
The statement that best described the growth rate of the Monarch butterfly after the Meadow was colonized would be that the population grows at a constant rate until it approaches 5,000 individuals, and then the population size remains stable.
The carrying capacity generally represents the maximum number of individuals of a particular species an environment can support based on the resources that the environment has. Ideally, the population only stabilizes with very minimal oscillation around the carrying capacity. It neither decreases nor increases significantly unless a major disruption happens.
The only option that addresses the stability of populations around the carrying capacity of the environment is option D.
The correct answer is D.

Lion and cheetah populations compete for the food source of zebras, and lions outcompete cheetah.
Limiting factors are those factors in the ecosystem which can limit the growth of population of a species in an ecosystem. Predation and competition are two limiting factors in the ecosystem that can decrease or extinct the population of a species. Predation is a limiting factor in which predatory organisms are dependent upon a prey organisms. This is natures way of limiting the surplus growth of prey population and to maintain a balance in ecological community. Competition is a limiting factor in which one or more same or different type of organisms compete for the same resource in an ecosystem. The one which is more competitive will derive those resources other than the one which is less competitive.
According to the given data, it is evident that the population decline in predator cheetah and lion populations because of decline in zebra population but the decline in cheetah population is more than that of lion. It explains the fact that lion is more competitive than cheetah in deriving the food which is already limited. Therefore, lion outcompete cheetah.
