11. Which of the following is an example of a pigment?
a. Glucose
c. Chlorophyll
b. Pyruvate
d. NADPH

Answers

The answer is C, Chlorophyll

Chlorophyll is an example of a pigment. Option C is correct.

The chlorophyll is the green pigment in the leaves. The chlorophyll absorbs the red and blue wavelengths of light from the sun. As a result, the light reflected from the leaves is less red and blue, making it appear green. Chlorophyll molecules are large.

Chlorophyll is made up of one central magnesium atom, surrounded by a ring of nitrogen-containing structures called porphyrins; attached to this ring is a chain of long carbon-hydrogen side chains called phytol chains.

The biosynthesis pathway of chlorophyll b involves the same enzyme as that of chlorophyllide.

Therefore the correct option is option C.

Yeast is added to bread dough before baking. After several minutes, the bread dough rises. Use your experiment to explain how respiration of yeast is important for the baking process.

Answers

Answer:

The purpose of any leavener is to produce the gas that makes bread rise. Yeast does this by feeding on the sugars in flour, and expelling carbon dioxide in the process.

While there are about 160 known species of yeast, Saccharomyces cerevisiae, commonly known as baker's yeast, is the one most often used in the kitchen. Yeast is tiny: Just one gram holds about 25 billion cells. That amount of fungi can churn out a significant amount of carbon dioxide, provided it has the simple sugars it uses as food. Fortunately, yeast can use its own enzymes to break down more complex sugars—like the granulated sugar in the activity below—into a form that it can consume.

Make a yeast-air balloon to get a better idea of what yeast can do

Yeast is a unicellular fungus which undergoes anaerobic respiration to produce ethanol and carbon dioxide gas.

How does yeast fermentation work in bread-making?In a process known as fermentation, yeast consumes the sugar present in the dough to produce carbon dioxide and alcohol.The dough is kept in a warm area throughout the baking process.Fermentation occurs as a result of heat.However, if the temperature is too high, the yeast is killed during the cooking process.As the dough ferments, carbon dioxide is created and trapped as microscopic air bubbles. The expansion of carbon dioxide during baking allows the bread to rise higher. During the bread-baking process, the alcohol created during fermentation evaporates.

This is how yeast fermentation plays a vital role in the baking process.

A virus has wiped out the grasshopper population in the area. What effects to the ecosystem will most likely occur?​

Answers

Answer:

Those who prey on grasshoppers will have their population decline while the grass population will rise.

Explanation:

Organisms need food to survive. If their food is gone, they won’t thrive as well. This isn’t saying they’ll go extinct, as they may have other food sources, but life will be harder with one food source gone. Since grasshoppers eat grass, the grass population will rise some due to a lack of predation. Hope it helps :)

Answers

Explanation:

The liver stores vitamin A, D, E, K and B12. The first four of these are all fat soluble. This means that the bile secreted during digestion is essential for absorbing them so that the body can use them. If bile production is compromised by liver damage, the proper absorption of these vitamins may be affected.

B:Extinction
C:Biodiversity level of the habitat
D:Carrying Capasity

Answers

Answer:

Carrying capacity

Explanation:

Section X represents the maximum population size that the environment can support.

Changes in a population of elk are shown in the graph given. The best representation by the letter X is the carrying capacity of the population. Thus, the correct option is D.

What is Carrying capacity?

The carrying capacity of an environment is the maximum population size of a biological species which can be sustained by that specific surrounding environment, it is given the food, habitat, water, and other resources that are available.

Carrying capacity can be defined as the environment's maximal load, which in population ecology corresponds to the particular population equilibrium of that area, when the number of deaths in a population equals the number of births as well as the immigration and emigration of individuals.

The effect of carrying capacity on the population dynamics is modelled through a logistic function. Carrying capacity is applied to the maximum population which an environment can support in the ecology, agriculture and fisheries.

Therefore, the correct option is D.

3. What is the scientific term for a group of interacting individuals of the same type, living in the same area at the same time?

Answers

Answer: The scientific name is called POPULATION.

Explanation:

In basic ecological studies, POPULATION is defined as a group of interacting individual of the same type or species, living in the same area or habitat and at the same time.

Furthermore, to study a population of organisms, the different characteristics seen include:

--> Population size: This is important as it affects the survival of a given species in a habitat. A small population may be easily wiped out by events such a fire but a large population stands a better chance of survival.

--> Population frequency: This is simply how often the species occurs at different sites in a habitat.

--> Population density: this is the average number of individuals of a species per unit area of the habitat.

--> Percentage cover: This is the area of ground occupied by a given species in its habitat.

--> Distribution: This is the way in which individuals of a particular population are arranged in a habitat. They may be clumped, evenly spaced or randomly spaced.
