Answer:

a) The question "Do pumpkins grow bigger when fed milk?" it is already a hypothesis, which means that to apply the scientific method, we should establish an experiment, where we would select a squash squash, feed some with milk and some without milk and wait a certain period of time. After that time, we could move on to the stage of the scientific method called "evaluation of results" where we would evaluate the differences in development and size between the pumpkins that were fed with milk and those that were not. After that we would go to the phase called "conclusion" where based on the comparison of the results we would answer the hypothesis shown above.

b) A scientific question could be "Can bean seeds germinate in sterile soil?"

Explanation:

Scientific method is a set of steps that must be followed when someone wants to prove a hypothesis based on experimental and scientific data. These steps are: visualization of something questionable, formulation of the hypothesis about it, establishment of a scientific experiment to test the hypothesis, evaluation of the results of the experiment and conclusion.

A scientific question is every question that you can perform a scientific experiment to answer it. This scientific experiment is carried out with the steps of the scientific method.

We ask the question: does milk make pumpkins grow bigger? We make the hypothesis that it does, and predict that watering pumpkins with milk will make them grow bigger, compared to those that aren't watered with milk. We take a sample of pumpkins (at least 30 or so) and water them normally, and another sample (also 30 or so) and water them with milk. After the pumpkins are grown, we collect them and measure their weight, and perform statistical analysis to see if there is any significant difference between pumpkins that are watered normally and those that are watered with milk.

Do plant stems still grow upwards when you suspend the plant upside down? would be a very good scientific question.

Answer:

(three) crossing over, mutations caused during crossing over, and independent assortment.

Explanation:

Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase I.

PLEASE HELP ME AND EXPLAIN!!! THANK U FOR THE HELP!!!

An example of a false negative is taking an HIV test and having the test come back negative to say the patient is clean, but in reality they have HIV. Another example of a false negative is a woman taking a pregnancy test saying "not pregnant" (i.e. test is negative), but she actually is pregnant. Between those two examples, it is better to have a false negative pregnancy test because it is non life threatening.

A false positive example would be getting bad news you have cancer, when you actually don't have cancer. Another false positive example is a test saying you have a cold virus, when in actuality you don't. The first example mentioned would have the patient likely go through intense chemo treatments which would greatly affect their livelihood. The second example is a more harmless false positive as it would involve at most a flu shot if anything.

Which of these is not part of insect immunity? A. enzyme activation of pathogen-killing chemicals B. activation of natural kille

Firlakuza [10]

Insect immunity doesn't include the property of an enzyme activation of pathogen-killing chemicals.

What is enzyme activation of pathogen?

Due to various trehalose's importance in pathogenic organisms, there has lately been a surge of interest in trehalose metabolism for therapeutic applications.

TPP (trehalose-6-phosphate phosphatase) is an important enzyme in the most important biosynthetic pathway (OtsAB).
The enzyme properties of recombinant TPPs from five key nematode and bacterial pathogens, including three new members of this protein family, are compared here.
The kinetics of trehalose-6-phosphate hydrolysis demonstrate that all five enzymes exhibit burst-like kinetic behaviour, defined by a drop in enzymatic rate beyond the pre-steady state.
Multiple global conformational changes in members of this enzyme family during substrate processing can explain the observed super-stoichiometric burst amplitudes.

Hence, the correct answer is option A
