how does water boiling on a stove represent all 3 types of heat transfer​

Answers

Answer:

For example, when a pot of water is placed on the stove to boil, conduction heat warms up the pot, which then heats the water molecules inside. As these molecules heat, convection causes them to move away from the interior of the pot as they are replaced by cooler molecules.

A student used a microscope to observe Elodea submerged in a solution. The student observed the cell cytoplasm pull away from the cell wall and clump together in the center of the cell. Which statement best explains why this occurred? A-The cell was submerged in a hypertonic solution. B-The cell was submerged in a hypotonic solution. C-The cell was submerged in a pure solution. D-The cell was submerged in an isotonic solution.

Answers

Answer:

A

Explanation:

The correct answer would be that the cell was submerged in a hypertonic solution.

A hypertonic solution is a solution with a higher concentration of solutes than that of the cytosol of a cell suspended in it. When a cell is suspended in a hypertonic solution, water moves osmotically from the cytosol to the hypertonic solution. This causes the cytoplasm to collapse and the cell becomes flaccid.

The correct option is A.

Answer:

D. The cell was submerged in a hypertonic solution.

Two students completed an experiment to determine if pesticide use at local farms was causing fish kills in a local pond. The steps of the experiment are listed below. Select one location to collect water samples in the pond. Collect a 5-mL water sample at 8 am for two days. Measure the amount of pesticide present in each sample using the same measurement tools. After analyzing their data, the students conclude that pesticide runoff from farms is not causing the fish to die in the pond. Which of these statements best describes why their conclusion is not reliable? The pesticide measurements were the dependent variable. The samples were collected at different times. The samples were only collected for two days. The time of sample collection was not an independent variable.

Answers

Answer:

The pesticide measurements were the dependent variable

Explanation:

According to this question, an experiment to determine if pesticide used at local farms was causing fish kills in a local pond was conducted by two students. They followed the following steps:

- Select one location to collect water samples in the pond.

- Collect a 5-mL water sample at 8 am for two days.

- Measure the amount of pesticide present in each sample using the same measurement tools

However, after analyzing the data, they concluded that "runoff from farms is not causing the fish to die in the pond". The students' conclusion is not reliable because THE PESTICIDE MEASUREMENTS WERE THE DEPENDENT VARIABLE.

Note that, the dependent variable in an experiment is the measured variable while the independent variable is the manipulated variable. In this case, the students ought to measure the death RATE OF FISH KILLS as the dependent variable instead. The PESTICIDE is the independent variable of the experiment not dependent variable. This was the reason for the unreliability of the conclusion.

Each strand of s DNA molecule contains nitrogenous bases that pair with other nitrogenous bases in very specific ways. A diagram of a section of DNA is shown. DNDA Strand 3' _|___|___|___|___|___|___|___|___|___|___|___|___|_ 5' T G T A G C T G C G C G T Which DNA strand is complementary to the one shown above?

Answers

Answer:

The complementary DNA strand, according to the nucleotide sequence of the other strand is 3' - A C A T C G A C G C G C A - 5'

Explanation:

Each strand of DNA is made up of specific sequences of the four nucleotides present in this molecule, adenine, thymine, cytosine and guanine.

In double-stranded DNA, one strand complements the other —according to the complementarity of nitrogenous bases— where a purine, adenine and guanine, are joined with a pyrimidine, thymine and cytosine, respectively:

Adenine is complemented with Thymine. Guanine is complemented with Cytosine.

According to this, the complementarity of the strands is:

    5' - T G T A G C T G C G C G T - 3'

    3' - A C A T C G A C G C G C A - 5'

The DNA strands remain linked by hydrogen bonds between their nitrogenous bases, until such time as they must be separated for transcription.

You need to find out why the GBR water is inhibiting (stopping) photosynthesis in the algae. The three major parts of photosynthesis are PSI, PSII and the Calvin cycle. The database has provided 3 things that could be inhibiting photosynthesis: high sea temperatures, paraquat, and diuron.

Answers

Answer:

Explanation:

The question is not complete below is the remaining part of the question

Justify your choice by writing a hypothesis to explain how it has stopped the algae from making ATP, NADPH and sugars. You will be able to revise your hypothesis as you do more experiments

Explanation:

The hypothesis will be

High sea temperature inhibit Algae growth

Herbicides reduces algae photosynthesis rate

Algae respond to temperature differently some thrive at a low temperature, some at a moderate temperature but when the temperature is very high the rate of photosynthesis will reduce because they can not undergo the normal body physiological function as a result of harsh environment. In green plant at a very high temperature stomata closes to regulate water loss this prevent Carbon dioxide from coming in and photosynthesis rate reduces

Paraquat and Diuron are herbicide that prevent the growth of plants, when they are sprayed Algae is affected they die from immediate action of this chemical and their colour changes since chloroplast the green pigment is where light hit for photosynthesis to occur when the color changes the active site is affected photosynthesis can no longer occur.

Answer:

Diuron

Explanation:

Increasing the temperature only decreases the sugar, not the ATP and NADPH. I predict that Diuron will be inhibiting photosynthesis because photosynthesis as a whole should not work if Photosystem II is interfered with. Also, because Paraquat only lowers NADPH and sugar and not ATP, Diuron is the only choice left.

3. A certain type of decorative lamp contains colored liquids. These liquids form globs that break off and rise to the top of the liquid. The globs rise due to _______________.Convection

hope this helps

Answer:

1) Conduction.

Heat transfers to a spoon as the heat energy is passed from the coffee to the spoon through conduction.

2) Radiation

The heat on the glass surface gets radiated into the chair which causes the chair to warm up.

3) Convection

The globs are hot and less dense, which rises to the top whereas the cold globs are more dense which causes it to settle down.
