Answer: Chicory will increase, because sweet peas appear to be sensitive to drought.
Explanation: I took the test on progress learning and it was right.
The table shows the average population of two competing weeds over a square meter of ground in a Georgia field. The table also gives the average rainfall for five successive years. If there was an extended drought in this area, what would be a reasonable prediction?
B. Encouraging a decrease in overconsumption
C. Building a much stronger economy
D. Using technologies that can harvest resources faster
Answer: B. Encouraging a decrease in overconsumption.
Explanation:
Sustainability can be define as the judicious use of the resources. This suggests that the use of the resources should be in a way so that they can meet the needs of the present as well as the future human population.
Among the options given, B. Encouraging a decrease in overconsumption. is the correct option. This is because of the fact that if the resources are overconsumed this will lead to the scarcity of the resources. This will not help in maintaining the sustainability of resources in the population.
The structure of an organism or its part, directly influences its function, which is central to biological adaptation. Adaptation involves developing physical characteristics, which aid survival in specific environments. While analogous structures represent adaptation to similar environments, homologous structures indicate shared ancestry.
Structure and function are fundamentally related to adaptation in biology. Essentially, the shape or structure of an organism, or any of its body parts, directly relates to that part's function or purpose. This idea, called the structure-function relationship, is central to the concept of adaptation—the process by which organisms evolve physical characteristics that help them survive in their environment.
For example, consider the fins of whales and the wings of bats. Even though these animals differ significantly in many aspects, they both developed structures (fins and wings) that perform similar functions (swimming and flying), which are best suited to their specific environment. These analogous structures represent an adaptation to a common environmental condition, despite the lack of a close evolutionary relationship, and is known as convergent evolution.
On the other hand, homologous structures represent a shared ancestry. For instance, the grasping hands of humans and chimpanzees, which serve the same function, indicate a common ancestor. Despite their structural similarities, the ways these structures are used could vary, showcasing how different environmental conditions can drive variations in function and contribute to evolutionary divergence.
A prime example of the structure-function relationship—the hallmark of adaptation—is observed in the various beak shapes of finches. Different shapes serve different purposes or functions, permitting birds to make the best use of available food resources in their respective habitats.

B. Bio genous Sediment
C. Hydrogenous sediment
D. Both A and B
The correct answer is option B, Bio genous Sediment
Reason -
The calcareous ooze is known as biogenous sediment as it has formed from the calcareous microscopic shells of the living organism. These oozes have primarily developed due to the deposition of soft muds in the ocean floor made up of calcium or diatoms or radiolarians.. These biogenous sediments are found in the form of a) mineral calcite and b) aragonite.
Calcareous ooze is an example of bio genous sediment and the correct option is option B.
Bio genous sediments are formed from the remains of marine organisms such as shells, skeletons, and other calcareous or siliceous materials.
Calcareous ooze specifically refers to sediment composed mainly of the calcium carbonate shells or tests of microscopic marine organisms like foraminifera and coccolithophores.
These organisms extract calcium carbonate from the water to build their protective structures, and when they die, their remains settle to the ocean floor, accumulating over time to form calcareous ooze. It is important to note that terrigenous sediments, which originate from land sources, can also mix with bio genous sediments in some areas, creating a combination of both types of sediment.
Thus, the ideal selection is option B.

B. Metaphase II
C. Mitosis
D. Prophase I
The correct answer is option D. Prophase I
The crossing over is a phenomena, which occur in the cells undergoing meiosis. In the process of crossing over, the exchange of the genetic material takes place between the sister chromatids. This process takes place in the prophase 1 stage of meiosis 1 in the gametes. The exchange of genetic material between chromatids cause recombination, and hence, genetic variation.
They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, ... However, there are radiometric dating methods that can be used on sedimentary rock, including luminescence dating
i hope this help
sorry if it wrong
