Which of the following best describes the producers in a terrestrial food web?
a- They convert energy from the sun to chemical energy.
b- They are at the top of the energy pyramid.
c- They are unaffected by decomposers.
d- They obtain their energy from consumers.
Answer:
The correct answer is - a- They convert energy from the sun to chemical energy.
Explanation:
Producers in any food web or ecosystem are the organism that can produce the food and energy on their own. Normally these organisms are green plants that can perform photosynthesis in order to produce chemical energy from light energy that comes from the sun.
Producers not only provide food and energy to themselves but also provide food and energy to each trophic level directly or indirectly. Producers are present at the base of the energy pyramid.
Tại sao tóc có mầu đen
Answer:
Melanin is responsible for black colour of hair.
Explanation:
Hair is black in colour because it is determined by the amount of a pigment present in hair is called melanin. If eumelanin which is a type of melanin, present in hair, it gives people black or brown hair. If the receptor is not activated or is blocked in the hair, then melanocytes make pheomelanin instead of eumelanin and then the black or brown hair colour did not occurs so we can conclude that melanin is responsible for black colour of hair.

can I get a real-life example of an exothermic reaction?
Answer:
The burning of the candle is an exothermic reaction. The candle is a paraffin wax which is made up of hydrocarbons. When the candle burns, it comes in the contact of oxygen, and there is a breaking of hydrocarbon bonds and hence the release of energy take placeAre chicken nuggets more like a taco or a hamburger?!?!?!

Determine the type of inhibition that has occurred in a first order Michaelis-Menten enzyme catalyzed reaction that has yielded the following data. Vi is the velocity in the presence of inhibitor, V is the velocity when run without inhibitor and [S] refers to the substrate concentration. [S] V Vi 3.333 0.283 0.055 1.000 0.260 0.054 0.400 0.222 0.052 0.263 0.197 0.051 0.179 0.171 0.049
Answer:
competitive inhibition
Explanation:
Given in the first order [tex]\text{Michaelis-Menten enzyme catalyzed reaction}[/tex].
[tex]$V_i$[/tex] = velocity in the presence of the inhibitor
V = velocity when run without the inhibitor.
S = substrate concentration
We need to plot a curve for [tex]$\frac{1}{[V]}$[/tex] vs [tex]$\frac{1}{[S]}$[/tex] and a second plot of [tex]$\frac{1}{[V_i]}$[/tex] vs [tex]$\frac{1}{[S]}$[/tex]
By plotting the curve we see that the slope and the intercept are not the same for the two curves.
And also, the [tex]$V_{max}$[/tex] for the second curve with the inhibitor is lower than the first curve.
Therefore, the inhibition type would be competitive.

please explain why the gastric glands secret pepsinogen and not pepsin
Answer:
The correct answer is - to protect the cells of these secretory glands from pepsin.
Explanation:
Pepsinogen is an inactive form of enzyme pepsin that is released by specific cells called chief cells within the gastric lining Releasing the inactive form of pepsin in preventing the auto-digestion of protective proteins and the cells of these secretory glands in the lining of the digestive tract.
Pepsinogen is activated by acidic pH to pepsin of the stomach lumen and the cell lining of the stomach is protected by mucus lining.

Explanation:
Role of liver in carbohydrate metabolism.
Answer:
In the metabolism of carbohydrates, the liver helps to ensure that the level of sugar in your blood (blood glucose) stays constant. If your blood sugar levels increase, for example after a meal, the liver removes sugar from blood supplied by the portal vein and stores it in the form of glycogen.

Which of the following is an organism whose cells each contain a membrane
bound nucleus?
Answer:
D. Eukaryote
Explanation:
An organism that has membrane-bound organelles will have more complex organelles like mitochondria, Golgi apparatus, and ER. These are known as Eukaryotes. Additionally, they will have a nucleus that has the DNA coiled inside. Prokaryotes do not have membrane-bound organelle and the DNA floats in the cytoplasm. Most plants and animals are eukaryotes and all multicellular organisms are too.

Which of the following statements about the energy needs of cells is false?
1. The most usable energy for cells comes from the rapid combustion of glucose
2. Many cellular reactions have an associated activation energy
3. The laws of thermodynamics force cells to acquire energy
4. Without a continuous input of energy, cell disorder will increase
Answer:
A the most usable energy for cells comes from the rapid combustion of glucose
The statement 'the most usable energy for cells comes from the rapid combustion of glucose' is FALSE (Option 1).
Glucose is a simple carbohydrate that provides a rapid energy source to the cells.In animals, glucose is used to produce glycogen, which is a complex carbohydrate that provides a long-term source of energy.All metabolic reactions in a cell depend on the presence of activation energy, which generally is provided by ATP, the energy coin of the cell.In conclusion, the statement 'the most usable energy for cells comes from the rapid combustion of glucose' is FALSE (Option 1).
