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.

Answer:

The Hershey–Chase experiment in 1952 confirmed that DNA (rather than protein) is the genetic material of the viruses that infect bacteria, providing further evidence that DNA is the molecule responsible for inheritance.

2. The cytoskeleton of animal cells includes three types of proteins, and the cytoskeleton of plant cells includes two types of
sineoko [7]

Answer:

A. Actin filaments and microtubules

B. intermediate filaments

Explanation:

Actin filaments and microtubules are two major building blocks that form part of the cytoskeleton in all eukaryotic cells. Both actin filaments and microtubules play a fundamental role in the dynamics of the cytoskeleton, and they are involved in many essential cellular processes including, among others, mitosis, cytokinesis, intracellular transport, cell signaling, etc. Moreover, intermediate filaments are very stable structures found in animal cells, where they extend from a ring around the cell nucleus to the plasma membrane in order to provide consistency and shape to the nuclear envelope.

Technique of placing a desired plant stem into another, more adequate root system is _____.
kaheart [24]

Answer:

grafting

Explanation:

The grafting is a horticultural technique that enables us to place a stem of a desired plant into another, more adequate already developed root system. This is done by cutting a branch from the already established plant, on the place of the precisely made cut we joint the desired stem, and then joint them together, be it with wax, mud, or a sellotape. The stem that has been placed on the established plant will be able to get the nutrients from it in this manner and become part of it, but it will produce different fruits from the established plant, it will produce its own fruits. This technique of course works only on plants that are more closely related and belong to the same family.

<h2>Proportion of mottled fish </h2>

Explanation:

  • A predator can be defined as an organism that makes the other organisms die to obtain them as food. Prey is the living being which is typically inferior and killed by the predator. Adaptation is a change in the physiology, morphology and genetic makeup of the organism which makes it suitable for survival in an unfavorable environment. Natural selection is the differential survival and reproduction of the organisms which exhibit better traits over the others
  • The population of the mottled fish is likely to increase due to natural selection. As the mottled fish color pattern match with that of the mottled background of the bottom of the lake. This will help the mottled fishes to camouflage the predator wading birds. These mottled fishes will remain undetected from the predator wading birds. The trait of the mottled pattern will be adapted by the light sandy brown fishes and the trait will be passed on the next generation as well. Hence, the proposition of the mottled fish will increase
  • Hence, the right answer is "the proportion of mottled fish will increase over time"
