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

The diffusion of a substance into or out of a cell requires
Answer:
Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane. Gas exchange in gills and lungs operates by this process. Carbon dioxide is produced by all cells as a result of cellular metabolic processes.
Explanation:
The diffusion of a substance into or out of a cell requires a process called diffusion, by which the molecules pass out through the plasma membrane.
What is diffusion?Diffusion is a key mechanism for material transfer within cells and for the passage of critical tiny molecules across the cell membrane. This process controls the exchange of gases in the gills and lungs. All cells release carbon dioxide as a byproduct of biological metabolism.
There are two processes by which the molecules pass through a semi-permeable membrane. The processes are osmosis and diffusion. When the material transfer from low concentration to higher concentration.
Thus, diffusion is the process by which molecules travel through the plasma membrane to allow material to enter or exit a cell.

Explanation:
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.
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.

Primary productivity
B
Gross primary productivity
С
Net primary productivity
D
Cellular respiration
Answer:
C. Net Primary productivity
Explanation:
In an the food chain of an ecosystem, energy is constantly being gained and most. Producers are the set of organisms that start the energy cycle via the process of photosynthesis. The gross primary productivity (GPP) is the amount of energy that the producer is able to capture from sunlight during photosynthesis.
The rate at which that captured energy is used to produce chemical organic compounds, which served as food, is called the primary productivity of the producer. However, the NET PRIMARY PRODUCTIVITY (NPP) is the energy available to consumers, which is determined by subtracting the energy used by plants via metabolism, from the total energy transformed by the process of photosynthesis. Hence, mathematically, NPP = GPP - R
Where, R = energy lost via respiration.

This can be used in the treatment of individuals currentlty infected with Ebola. Explain why the blood plasma from survivors can be used to treat new cases of Ebola infection.
Answer:
This was the only treatment options adopted for the Ebola in 1995 in the Democratic Republic of Congo. The assumption was that immune response is generated by the virus in the WBC of the infected individuals. These response produce antibodies.
A total if 8 patients were transfused with these blood contained antibodies, but one of these died, the remaining 7 patients survived.
The antibodies were believed to have multiplied(produced b-cells) to neutralize the Ebola virus(antigens) and to ensure the survival of the patients

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.

A radioactive substance has a half-life of 1.25 million years. What is the age of a rock in which 6.25% of the original radioactive atoms remain? 5 million years old 6.25 million years old 3.75 million years old6 2.5 million years old 1.25 million years old 625 thousand years old
Answer:
The age of the rock is 5 million years
Explanation:
Fraction of radioactive substance remaining = 6.25% = 625/10000 = 1/16
Number of half-lives undergone by the substance to leave behind 1/16 of the original sample
1/16 = (1/2) * (1/2) * (1/2) *(1/2)
Therefore, the substance have decayed 4 times
One half=life = 1.25 million years
Four half-lives = 4 * 1.25 million years = 5 million years
Therefore, the age of the rock is 5 million years

Phenylalanine is required for the production of many bodily proteins, but none of your cells are capable of synthesizing this essential amino acid. What type of metabolic pathway must be responsible for providing phenylalanine to your cells? How would your diet effect the mount of Phenylalanine that is available?
Answer and explanation:
Phenylalanine is an amino acid that is very important for our bodies to function correctly but it isn't synthesized in our cells, so the only way to incorporate it is by having it in our diets, this is why phenylalanine is an essential amino acid.
Phenylalanine can be found in milk, eggs, chicken, and liver, among other foods known to be good protein sources. Given the fact that phenylalanine is an essential amino acid, the amount we ingest of it in our diet will directly impact on the availability of this amino acid in our body.
Phenylalanine is an amino acid and, as such, it will enter the metabolic pathway of protein catabolism, where it will be degraded to be fully usable for the body. Phenylalanine will be metabolized into acetoacetic acid and fumaric acid, and is the precursor of catecholamines such as epinephrine and norepinephrine, while also being part of the structure of several neuropeptides.
