explain how pH and temperature can affect enzyme activity
Please help has to be due in 20 mins. Thank you for helping me.

Answers

Answer:

Enzyme activity depends on many factors such as Substrate concentration, enzyme cofactor, enzyme inhibitors, pH, and temperature. pH and temperature are two important factors that directly affect the activity of an enzyme as follows:

1. pH

Each enzyme has the specific optimal pH that allows it to perform its function to its fullest. The enzymes are the protein made up of the interaction of the hydrogen bond in the side chain of the protein. if there is any change from optimum pH, the enzyme activity decreases until it stops working.

2. Temperature:

Each enzyme has its own optimal temperature. Any modification or change in temperature results in the activity of an enzyme, and it also leads to the denaturation of an enzyme as it is made up of protein.

One of the bacteria in Model 1 has a tail-like structure.
a) What is the structure called?
b) What might be the purpose of this structure?
c) Based on your answer of the previous question, what might you infer about the absence of this structure in the other two bacteria cells?​

Answers

From the bacterial model:

(a) the tail-like structure is known as the flagellum (plural, flagella)

(b) The primary function of the structure is to aid movement. It is moved in a whip-like version to propel the organism.

(c) Based on the absence of of flagellum in the other two bacteria, it means that they are not motile.

The presence of flagellum in bacteria is an indication that such bacteria are motile. The thread-like structure is whipped randomly in order for the organism to move and the absence of it in an bacterium is an indication that such a bacterium is not motile.

True or False: When a biotic factor dies, the molecules within that
organism enter into the nutrient cycle.

Answers

Answer:

Explanation:

True

When a biotic factor dies, the molecules within that organism enter into the nutrient cycle is a true statement.

Biotic factors:

There are two factors in a living system. Biotic and abiotic. all living organisms are biotic components. Plants, animals, and other living components are biotic components. Air, water, and sunlight are abiotic components.

Biotic and abiotic components together make the nutrient cycle. When biotic components die their molecules enter the nutrient cycle. Microorganisms act on the biotic component when they die.  

They release carbon, hydrogen, and other molecules into the atmosphere when they die.

Therefore, When a biotic factor dies, the molecules within that organism enter into the nutrient cycle is a true statement.

What is the source of most salt in the ocean?
A.fish
B.human activity
C. Wind
D. Rocks on land

Answers

Answer:

D. rocks on land

Explanation:

Salt in the ocean comes from two sources: runoff from the land and openings in the seafloor. Rocks on land are the major source of salts dissolved in seawater. Rainwater that falls on land is slightly acidic, so it erodes rocks. This releases ions that are carried away to streams and rivers that eventually feed into the ocean.

Answer:

Option D Rocks on land

BT crops are developed by adding traits from which of the following organisms?


phytoplankton

bacteria

viruses

Answers

Answer:

bacteria

Explanation:

'Bt' crops are genetically modified crops that contains a certain gene of a bacteria called Bacillus thuringiensis. The name of this GM or transgenic crop was coined from the bacteria used.

The gene coding for the toxic traits of the bacteria are added into Bt crops e.g cotton, hence, the crops become resistant to pest attack. Therefore, according to this question, BT crops are developed by adding traits from BACTERIA.

Answer:

Condensation is a process in which water vapors changed into liquid state.

Explanation:

Condensation is a process in which water that is present in the vapors form changed into liquid state. Condensation greatly affect Earth systems because this process is responsible for the precipitation on the earth. Condensation occurs in the atmosphere when warm air rises in the atmosphere, cools and unable to hold water vapor. As a result, water vapors condenses to form cloud droplets that falls in the form of rainfall.

What is needed for a fossil to form? Select all that apply.

1. The organism must first get stuck in rock.

2. The soft tissue of the dead organism must be eaten by scavengers before the bones can be preserved.

3. The tracks or burrows of an organism must be filled with sediments before they are disturbed.

4. The organism's body must be covered by sediment or another substance before its body decays.

Answers

I like 4 the best. If an organism is covered by sediment before the body decays the sediment can harden around the decaying body and the imprint will be preserved in the hardened sediment.

The correct answer is:The organism's body must be covered by sediment or another substance before its body decays.

What is the explaining statement for the same ?

Explanation: For a fossil to form, the organism's body must be rapidly buried in sediment, ash, or another substance before it can decay or be eaten by scavengers.

Over time, the minerals in the surrounding sediment or substance can replace the organic material in the bones, forming a fossil. Tracks, burrows, and other trace fossils can also form when sediment or another substance fills in the impressions left by an organism before they are disturbed.

Getting stuck in rock is not necessarily a requirement for fossilization, as fossils can also form in sedimentary rock or other types of rock.

Lack of oxygen: Decay requires oxygen, so organisms are more likely to fossilize in environments where oxygen is limited or absent, such as in deep water, bogs, or quicksand.

Low acidity: Acidic environments can dissolve bones and other hard parts, so fossils are more likely to form in environments with neutral or basic pH levels.

Lack of disturbance: Fossils are more likely to be preserved if they are not disturbed after burial. For example, if an organism's body is exposed to air or water before it can be buried, the bones may be scattered or destroyed.

Overall, fossilization is a rare and complex process that requires a combination of specific conditions to occur. As a result, the fossil record provides only a partial and biased glimpse into the history of life on Earth.
