Which of the following is not a function of carbohydrates?
A) storage
B) energy
C) structure
D) genetic material
Answer:
A) Storage
Explanation: Hope it helps!!
Starch is the primary energy source in most populations, but it must first be dissolved before it can be absorbed. Thus, option A is correct.
What is the role of carbohydrate in the metabolism?Sugar molecules make up carbohydrates, or carbs. Carbohydrates are one of the three primary nutrients included in foods and beverages, along with proteins and fats.
Because they play a part in several biosynthetic pathways and the creation of energy, carbohydrates play a significant function in metabolism.
Glucose is created by your body's breakdown of carbs. The body converts carbohydrates into glucose, a form of sugar.
At every stage of life, carbohydrates, commonly referred to as carbs, are essential. They are the main energy source for the body and the preferred energy source for the brain.
Therefore, storage is not a function of carbohydrates.

Which best describes the ecosystem at Point C?
O A. There are plenty of resources.
B. Population growth is exponential
O c. The beetles are competing for resources
O D. It has not reached carrying capacity
Answer:
The correct answer is option C.
Explanation:
The graph shows that a controlled population of beetles, where other individuals do not leave or enter, experiences progressive growth from point A to C and plateau over time. This is because the population has sufficient resources to guarantee their development, the birth rate increases than the rate of mortality and there is no competition for these resources.
The adequate amount of resources allows that at point C, the carrying capacity is almost reached, which is the result of competition among members of the same species, which ensures that the net population growth rate is going to decrease or go stable due to limited resources..
Answer:
C. The beetle are competing for resources

what order do the changes in the succession of an ecosystem occur? Rearrange the boxes so that the first change to occur is on the left and the last change to occur is on the right.
Answer:
You have to add a picture of the boxes g , but heres a explantion
Explanation:
Ecological succession breaks down into three fundamental phases: primary and secondary succession, and a climax state. The study of ecological succession generally focuses on the plants present on a particular site. But animal populations also shift over time in response to the changing habitat.

a population is made up of different communities in an area true or false
Answer:
True.
Explanation:
A population is made up of different communities in an area. This statement is false. A community is made up of different populations.
What is a community?A community consists of different species living in a particular area. An example is that a community may consist of the tiger population, the elephant population, the deer population, etc.
A population is a group of similar individuals present in a particular area, for example, a population of elephants, a population of tigers, etc. In the population, all the organisms belong to a single species.
Different populations interact with each other to make a community. Different communities make up an ecosystem. The ecosystem consists of both biotic and abiotic components. The biotic component includes all living animals and plants. Abiotic components include all the non-living substances such as air, water, soil, etc.
Hence, the community is made up of various populations, but the population is not made up of communities. So the given statement is false.

Interpret: Directional selection occurs when individuals at one end of a range are more likely to survive than intermediate individuals or individuals at the opposite end of the range. Stabilizing selection occurs when intermediate individuals are the most likely to survive.
Is directional selection, stabilizing selection, or both operating in this example? Explain.
Think and discuss: Evolution is the process by which populations of organisms can change over time. How is directional selection related to evolution?
Answer:
Stabilizing selection occurs when intermediate individuals are the most likely to survive.
Explanation:
Both because for example the birds with larger beaks could survive the drought and after 2 years stabilizing selection also occurs.
Answers:
Directional selection occurs when individuals with traits on one side of mean in their population survive or reproduce more than those on the other.
Hope it helps you.
Answer:
I believe both directional and stabilizing selection are operating in this example since only the large-beaked finches were able to survive the drought while the smallest-beaked finches disappeared. But also, we need to highlight after the second year stabilizing selection occurred because finches with large beak depth were the most likely to survive than those with smaller beaks, that is why that specific type of beak became more common.

Explanation:
A river flows into a lake. A community builds a dam to divert the river for crop irrigation use before it reaches the lake. Which describes a way in which biodiversity in the lake will be directly affected by this change?
Select one:
The size of the lake will increase, attracting more organisms who rely on it as a water source.
Nutrient levels in the lake will increase, encouraging the growth of new plants.
With less water flowing into the lake, the water temperature increases. Some species are unable to survive in the warmer water.
Diverting the river will introduce new, invasive species into the lake.
Answer:
With less water flowing into the lake, the water temperature increases. Some species are unable to survive in the warmer water.
Explanation:
Biodiversity of a lake is dependent on the flows from rivers. The health of the biota of the lake would be greatly affected when there is reduced flow of water from the river as a result of diversion into dams for agriculture purpose.
The major impact reduced water flow will have on the biota of the lake is that many species that cannot tolerate draught as a result of increase in water temperature caused by reduced flow of water, would eventually become extinct. The biota of the lake would diminish or decline.
