Answer:

Anaerobic respiration

Explanation:

Bacteria can perform both aerobic and anaerobic respiration. They perform aerobic respiration when oxygen is present. They perform anaerobic respiration in the absence of oxygen.

These processes breakdown glucose to generate ATP to power cellular processes.

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.

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:

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

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.

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.

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.

Answer:

Diffusion is a passive process of transport.

Endocytosis is a type of active transport

exocytosis are active transport processes.

osmosis a form or passive transport

Facilitated diffusion is a type of passive transport

Hope this helps!!!!

Classifying each type of cell transport :

A passive transport system is the movement of solute in solution across regions of different electrochemical potentials on either side of a cell membrane  ( i.e. from higher concentration to lower concentration) examples include : diffusion, osmosis and facilitated diffusion.  while

Active transport system is the movement of molecules across a cell membrane by the application of cellular energy and not the difference in electrochemical potential. examples include  Endocytosis and exocytosis

Hence we can conclude that Classifying each type of cell transport :Diffusion ; Passive transport.  Endocytosis :  Active transport. Exocytosis :  Active transport.  Facilitated diffusion : Passive transport. Osmosis :   Passive transport .

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".

Answer:

organisms evolve in order to better equip them to survive in their environment

Explanation:

for example, polar bears have white fur so they can blend into their environment.

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.

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.
