Answer:
50mL
Explanation:
Density is inversely proportional to volume.
This implies that, for the same mass of water, the higher the volume, the less dense it is.
By comparison 500ml is greater than 50ml
Going by the above analysis, 50ml will be less dense than 500ml because it is smaller.

Answer:
Oceanic plate
Explanation:
The oceanic plate is the thinner but denser plate. At a convergent margin, this plate is known to subduct under the lighter continental plate.
Oceanic plates have an average thickness of about 6km. They are rich in ferromagnessian minerals. These minerals are much denser than those of the silicates that make up the continental plate.
Oceanic plates produce volcanic rocks especially basalts when they melt. They have a density of 3.0g/cm³ whereas continental plates have a density of 2.7g/cm³1 po

Answer:
5. c. active transport of molecules across a membrane
6. b. osmosis
7. d. water entered the cells of the lettuce by osmosis
Explanation:
5. The diffusion of water does not involve the budding of the cell membrane. The production of proteins amino acids and asexual reproduction are unrelated to the movement of molecules across the cell membrane. Therefore, this is active transport of molecules across a membrane.
6. The diffusion of water from a high concentration to a low concentration of water across a selectively permeable membrane is called osmosis. Transpiration is the process by which water leaves plant cells. Active transport requires energy. Capillary action is when water moves as a result of adhesion/cohesion.
7. When water enters the cells by osmosis, the cells become more turgid, making the lettuce crisp.
what happens to a enzyme after it has completed a reaction?
Answer: The enzyme will always return to its original state at the completion of the reaction. One of the important properties of enzymes is that they remain ultimately unchanged by the reactions they catalyze. After an enzyme is done catalyzing a reaction, it releases its products (substrates).
Enzymes are not consumed in the reaction, they can continue catalyzing more reactions, they can remain bound to the product or they can be degraded.
What are enzymes?Enzymes are biomolecules that catalyze chemical reactions in living organisms. They are typically proteins, although RNA molecules known as ribozymes also exist. Enzymes are responsible for many of the metabolic processes that occur in cells and are essential for life. They are highly specific, meaning that they typically only catalyze one or a few specific reactions, and they increase the rate of reactions by reducing the activation energy required for the reaction to occur.
After an enzyme has completed a reaction, it is still present and can continue to catalyze more reactions. Enzymes can catalyze thousands of reactions per second, and they can remain active for long periods of time. However, enzymes can also be inactivated or destroyed by various factors, such as high temperatures, changes in pH, or the presence of certain chemicals

Answer:
Binary fission
Explanation:
Binary fission is a type of asexual reproduction in bacteria in which two identical daughter cells arise from a new cell. It is asexual in the sense that it does not require two parents but only one.
According to this question, Salmonella typhi is a bacteria that reproduces by splitting into two identical organisms. This is evidently a type of BINARY FISSION reproduction by the bacteria cell.

How are the health impacts of surface mining different from those of underground mining?
1. higher risk of mine collapse in surface mining
2. higher risk of lung disease in surface mining
3. Lower risk of hearing loss and surface my mining
4. Lower risk of minor injuries and service my mining
Answer:
4. Lower risk of minor injuries and service my mining
Explanation:
There is lower risk of minor injuries in surface mining because in surface mining the mine workers work in the open air as compared to underground mining. In underground mining there is a high risk of mine collapse which results in the death of the mine workers. There is risk of injuries in surface mining such as hearing loss because of high noise of the mining machines.
The impact on health of surface should be option 4. Lower risk of minor injuries and service my mining
Impact on health:There should be less risk of minor injuries in surface mining since in the case of surface mining the mineworkers work in the open air than underground mining. Since in underground mining there is a high risk of a mine collapse that leads in the death of the mineworkers.

A toy car accelerates 1.25 m/s2 when a child pushes it with a force of 0.1 newtons. What is the mass of
the car?
Answer:
0.089
Explanation:
The formula to solve for mass is:
m=F/a
So, The force is 0.1, and the acceleration is 1.25^2.
First you must square 1.25, which will give you 1.12 ( I rounded).
Now, we have 0.1/1.12, which equals 0.089, or 0.09.

A wet mount of unstained Elodea ( a green aquatic plant) is observed using high power (400x) of a compound light microscope. Which structures would most likely be observed? ribosome, Golgi complex, and vacuole ribosome, Golgi complex, and vacuole nucleus, chloroplast, and cell wall nucleus, chloroplast, and cell wall centrosome, lysosome, and plasma membrane centrosome, lysosome, and plasma membrane cytoplasm, endoplasmic reticulum, and nucleolus
Answer:
The correct option is "nucleus, chloroplast, and cell wall"
Explanation:
The specimen described in the question is said to be green aquatic plant. Hence, the organelles expected to be viewed are those present in a pant cell.
Although, nucleus (stores the genetic material) is present in both plant and animal cells, however, chloroplast (to provide the green colour for the aquatic plant) and cell wall (for the cell's rigidity and support) are only found in a plant cells.
Jaime and Ryan first noticed that something was wrong with their newborn baby about four months after birth. Their baby seemed to be having difficulty holding her head up. After a series of tests, it was noticed that fatty acids were not being digested by the cells and were accumulating on the child's nerve cells. Which organelle is not properly functioning in the cells of Jaime and Ryan's newborn baby?
Answer:
Liver
Explanation:
The liver is an organelle in the human body that is responsible for the digestion of fat. Liver produces bile, a digestive juice that helps in the digestion of fats and vitamins. Bile juice is stored in the gall bladder and move into the small intestine for the digestion of fat.
As per the details in the question, a newborn baby is unable to digest fat which is affecting the child's nerve cells. It means the newborn baby's liver is not functioning properly and not making bile juice that can digest the fat properly.
Hence, the correct answer is "Liver".
