Please help!! Null and alternative hypotheses and chi square. Please DO NOT give a fake garbage answer so you can get the points. I have posted this question like 4 times and only gotten those fake answers. If you do that, I will completely lose it and, so help, me, I will rip you to pieces. If you give me a legit answer- thank you so much, I am so grateful, you are being a nice person and have a great day.

Answers

Answer 1

Answer: I don’t know about alternative or chi square but a bull hypothesis from what I know is saying that your claim or thesis is wrong.

I hope that helped. :)

The Florida Everglades are one of the most diverse ecosystems in the United States and are home to many species of birds, reptiles, amphibians, and fish. Recently, scientists have investigated and determined that the population of pythons, which are from Asia, has increased greatly. What question is least likely to be asked based on these results?

Answers

This is recurring question. Since you didn't provide the choices I'll provide it including the correct answers based on the same question posted here before.

Options:
Are the pythons a new species?How can the python population be controlled?How quickly are pythons reproducing in the Everglades?How are the pythons affecting other animal populations?

The answer is "Are pythons a new species?"The Florida everglade is diverse in ecosystem, therefore, its obvious to have pythons in such an ecosystem.

Humans have used food processing to preserve the length of time that food can be eaten. Chemicals are added to the food to reduce bacterial growth, produce less toxins, and improve taste. Which best describes the advantages of food processing?

Answers

Answer: A control density dependent limiting factor.

A food processing is a process of increasing the shelf life of preventing the growth of bacteria and improving it's taste. A density dependent limiting factor is the one which affects the size and growth of the population depending upon the density of the population. Food is a density dependent limiting factor as it effects and availability are dependent upon the density of the population.

Food processing is advantageous in a sense as it maintains the quality of food hence, is a control over density dependent limiting factor.

Imagine you are in a laboratory. You are exploring the following reaction: A + B → C When the product C is created, bubbles form. When 10mL of A is added to 10mL of B, the reaction takes twenty seconds. Your teacher gives you three unknown substances (X, Y, and Z), one of which is a catalyst for the reaction. Design an experiment to test substances X, Y, and Z to determine which one is a catalyst for the reaction.

Answers

Ok so in this experiment what we want to find is the catalyst for the reaction. Our original reaction is the following. A + B --> C, therefore to find which of the unknown substances (X, Y, and Z) is the catalyst reaction we simply have to do the following:

A + B + X --> C

A + B + Y --> C

A + B + Z --> C

The reaction that produces C much faster than our original reaction A + B --> C will be our catalyst. The reason being that one of the substances will increase the rate of the chemical reaction.

I hope it helps, Regards.

Answer:

Prepare three test tubes containing reactant A.

Prepare three test tubes containing reactant B.

Add one test tube of reactant B and one unknown to one test tube of reactant A. Repeat for the other two unknowns.

Time the reaction until bubbling stops.

The unknown that causes the reaction to occur the quickest is the catalyst.

If an organism is composed of only one cell, it ___________. performs all of the functions is specialized does not have any functions cannot survive on its own

Answers

The given blank can be filled with performs all the function.

In case of unicellular organisms, which have a single cell, this single cell perform all the function. For a living organism, responding to stimuli, reproduction, obtaining nutrition, excretion and performing all the metabolic process is necessary. If the organism is made up of single cell, that single cell will perform all these functions necessary for life, other wise, it would be dead.

It performs all of the functions. In order for that organism to survive, all of its needs need to be met by that one cell. If that cell isn't performing all the tasks needed to survive, the organism will die.

PLEASE HELP ME FAASSSTTTT Compare and contrast genetic engineering to the process of natural selection. Select all statements that are true.

1) By selecting the genetic information that is passed on to future generations, genetic engineering is similar to natural selection.

2) Unlike natural selection, genetic engineering selects the organisms most beneficial to the environment.

3) By selecting the genetic information that is passed on to future generations, genetic engineering can happen at a different rate than natural selection.

4) Like natural selection, genetic engineering may be used on all organisms, including humans.

5) The effects of genetic engineering apply only to the organism selected, but natural selection affects the entire population.

Answers

Answer:

1) By selecting the genetic information that is passed on to future generations, genetic engineering is similar to natural selection.

3) By selecting the genetic information that is passed on to future generations, genetic engineering can happen at a different rate than natural selection.

4) Like natural selection, genetic engineering may be used on all organisms, including humans.

Explanation: In natural selection there is overtime selection for one particular trait and is mostly based on phenotype, whilst genetic engineering uses genotype of an organism and it is the deliberate modification of an organism by manipulating the genetic material
