When studying animal behavior, the distribution of organisms within a choice chamber can be studied to identify animal preferences. 20 Isopods are placed in a 2-choice choice chamber. A cotton ball dampened with distilled water is placed in Chamber A; A dry cotton ball is placed in Chamber B. After 15 minutes 2 Isopods are located in Chamber B, and 18 isopods are found in Chamber A. Perform the chi-squared test to determine if the distribution of isopods is significant or due to random chance.
a) chi-squared is 1.20, no it is not significant
b) chi-squared is 8.42, no its not significant
c) Chi-squared = 12.8, yes it is significant
d) Chi-squared is 18.59, yes it is significant
Answer:
c
Explanation:
Random distribution of the Isopods should be 50/50 in A and B.
Chi-square = [tex]\frac{(O - E)^2}{E}[/tex] where O = observed frequency and E = expected frequency
Chamber O E Chi-square
A 18 10 [tex]\frac{(18 - 10)^2}{10}[/tex] = 6.4
B 2 10 [tex]\frac{(2 - 10)^2}{10}[/tex] = 6.4
Total Chi-square = 6.4 + 6.4 = 12.8
Degree of freedom = 2 - 1 = 1
Tabulated Chi-square (α = 0.05) = 3.8415
The calculated Chi-square exceeds the critical value, hence, it is significant and not due to random.
The correct option is c.

how does increasing the size of the habitat affect carrying? explain your answer. recall the scenarios: 0-15 years, little land; 15-30 tears, moderate land;30-45 years, ample land
plzzz helpp
I meant years not tears
Answer:
so basically carrying capacity is "the amount of organisms a specific environment can support", so if the environment is increased, most likely, more space and food will be available, which means the environment can hold more organisms, causing the carrying capacity to increase
Explanation:
what I just said lol
Answer:
Increasing the habitat size will increase the carrying capacity. Carrying capacity is the maximum amount of organisms a habitat and its resources can carry. So if the habitat expands and more resources become available, the population would expand. As you can see for the first 15 years, when it was the little land, there was only about () rabbits, but as the land grew throughout the years, the rabbit population grew. 15-30 years with moderate land had around () rabbits, and the ample land in years 30-45 had around () rabbits, a little over two times the amount the little land had.
Explanation:
just fill in the ()s with the numbers that show on the graph. This is kinda late but hopefully it'll help anyone who needs it.

D. Mesosphere
Explanation:
Molecules that make up living things and contain carbon are called __________ molecules.
Molecules that make up living things and contain carbon are called organic molecules.
Organic molecules are those that derive their three-dimensional configurations primarily from their carbon skeletons.
Organic molecules are essential for the birth, development and functioning of all cells that make up living organisms.
About organic molecules:
All organic molecules contain carbon and practically always hydrogen, it is also frequent that they have oxygen or nitrogen.These chemical elements enable multiple and covalent bonds to be established, allow carbon atoms to develop three-dimensional skeletons, and give rise to multiple functional groups. Proteins, vitamins, carbohydrates, lipids, and nucleic acids are organic biomolecules, which are synthesized by living organisms.Therefore, we can conclude that molecules that make up living things and contain carbon are called organic molecules, which a living being needs to develop normally.

Nutrition is a common topic in the media, whether it's a new diet plan or a new "superfood" on the market to benefit
our health. Some of these products are scientifically sound, while others aren't. How do we tell the difference?
PLEASE HURRY
Answer:
To find out whether a product is scientifically sound, check the FDA standards for the product. Another option is to ask a medical expert, such as a doctor or a nutrition scientist, whether the product is scientifically sound.

how does carbon moves from the atmosphere to the biosphere?
Answer:
Via a range of pathways, carbon travels from one storage reservoir to another. In the food chain, for example, plants, by photosynthesis, transfer carbon from the atmosphere into the biosphere. Respiration, excretion, and decomposition release the fuel, continuing the cycle, back into the atmosphere or soil.

12. If hatching brine shrimp is related to salinity (how salty the water is),
then the greater the salt concentration, the higher the hatching rate.
Nour answer
Answer:
Independent variable: Salinity/Salt concentration
Dependent variable: hatching rate
Explanation:
As rightly stated in this question, INDEPENDENT VARIABLE, in an experiment, is the variable that the experimenter changes or manipulates in order to bring about a measurable response while the DEPENDENT VARIABLE is the variable that the experimenter measures in an experiment. Dependent variable as the name implies is dependent on the independent variable.
In this question where an hypothesis was given as follows: "Hatching brine shrimp is related to salinity (how salty the water is), then the greater the salt concentration, the higher the hatching rate". The hypothesis relates the independent and dependent variables i.e. it tells us how the independent variable affects the dependent variable.
Hence, according to the hypothesis, it is telling us how a change in SALINITY OR SALT CONCENTRATION will affect HATCHING RATE. Therefore;
Independent variable: SALINITY/SALT CONCENTRATION
Dependent variable: HATCHING RATE

As a scientist employed by the FDA, you've been asked to sit on a panel to evaluate a pharmaceutical company's application for approval of a new weight loss drug called Fat Away. The company has submitted a report summarizing the results of their animal and human testing. In the report, it was noted that Fat Away works by affecting the electron transport chain. It decreases the synthesis of ATP by making the mitochondrial membrane permeable to H+, which allows H+ to leak from the intermembrane space to the mitochondrial matrix. This effect leads to weight loss.How would you explain the decreased synthesis of ATP?
Answer:
The right response is "body temperature".
Explanation:
Whilst also growing the basal leakage of protons, this same drug Fat blocks the development of ATP. The whole change throughout the electrochemical gradient including its proton, therefore, induces the release of a possible form of radiation, rather than being transferred to ATP. Through thermoregulatory autophagy, outlet temperature throughout the individual contributes to loss, associated with elevated body temperature. Elevated body temperature would have the additional effect of removing fat.GUYS HELP FAST I GOT 3 minutes

What is the process depicted in this figure and why is it important?
Answer:
The correct answer is - antigenic shift due to mutation.
Explanation:
In this image, there is a representation of the antigenic shift or change takes place to evolve to a new strain of influenza virus from the original virus that has a different antigen on the surface of the virus than the new strain. In this image it is shown that the surface H antigens went through a shift to form a new strain while N antigen remain the same.
This is important to adapt and evolve according the internal environment of the host show this type of mutation requires if moving from one host to another (human to pigs).

Explanation:
A eukaryotic cell contains membrane-bound organelles such as a nucleus, mitochondria, and an endoplasmic reticulum. Organisms based on the eukaryotic cell include protozoa, fungi, plants, and animals. These organisms are grouped into the biological domain Eukaryota.
Any organism which has a closed membrane for a nucleas is a eukaryotic cell.
(organisms who dont have a nuclear memebrane is called prokaryotic cell)
We have eukaryotic cells as we have nuclear membrane but a bactaria(a prokaryotic cell) doesnt have a nuclear memebrane and all of its nuclear substances are floating insdie it getting jumbled up.
