Answer: The correct answer for the blank is -
Sepal, petal, stamen, and pistil.
Flower is the reproductive structure of flowering plants (angisperms). It is primarily composed of four parts, which are (from outside to innerside) -
Sepals (that together form calyx, the outermost protective whorl)
Petals (that together form corolla, the second whorl)
Stamen (the male reproductive part that together forms androecium, which is the male reproductive organ).
Stamen is further composed of anther (that produces pollen) and filament (stalk like structure, which protects anther).
Pistil (the innermost part that forms gynoecium, which is the female reproductive organ). It is composed of stigma, style, and ovary.

environment? Explain.
Answer:
I am answering just from my knowledge
The factors that have contributed to an increase in human population are two main e.g Increase in birth rate and decrease in death rate.
Increase in birth rate is due to more food production and food supply.Massive increase in agricultural productivity.More life expectancy etc.There is a decrease in death rate beacauseof eradication of diseases,better hygiene,cleanliness and development in medical facilities. Similarly, populations of organisms respond to external factors for a collective benefit. All populations must have an adequate amount of food, water, shelter, and space. ... Biotic factors like predation and competition for food are also limiting factors.the technologies used to achieve this transformation have caused unprecedented changes to Earth’s environment, altering ecosystems to the point where some may be in danger of collapse. The depletion of the ozone layer, erosion due to acid rain, and damage from global climate change are caused by human activities. The ultimate effect of these changes on our carrying capacity is unknown. As some point out, it is likely that the negative effects of increasing carrying capacity will outweigh the positive ones—the world’s carrying capacity for human beings might actually decrease.good luck
The increase in the human population's survival rate can be attributed to advances in medical technology, improved sanitation, and enhanced nutrition.
Several factors have significantly contributed to an increase in the survival rate of the human population and consequently to its homeostasis within its environment. Among these key influences include advances in medical technology, improved sanitation, and enhanced nutrition.
Medical technology advancements, such as vaccinations and antibiotics, have significantly reduced mortality rates, especially among infants and children. Coupled with an overall improvement in healthcare services, these interventions have extended life expectancy.
Improved sanitation has also played a significant role in increasing the survival rate. Access to clean water and waste disposal systems prevent the spread of disease, improving overall public health. Moreover, legislation and increased awareness of hygiene principles have made environments safer for human habitation.
Furthermore, an enhanced nutrition contributes to a healthier population, building immunity and strengthening the human body against illnesses. Expansion of food production technologies and improved transport infrastructure have ensured more balanced diets for a larger portion of the population.
These factors collectively contribute to the population homeostasis. A lower mortality rate coupled with a stable birth rate maintains a balanced population growth. Additionally, healthier individuals can interact more harmoniously with their environment, preserving resources more effectively for future generations.

2)Which best describes the aquifers?
Aquifers 1 and 3 may result in a reduced river flow.
Aquifer 2 may result in reduced surface water levels.
Aquifers 2 and 3 may result in decreased wetland and spring discharge.
Aquifer 3 may result in an increase in productivity.
3)How can recycling materials lead to environmental sustainability?
a.
Recycling materials helps decrease the amount of new materials taken from the environment.
b.
Recycling materials helps increase the rate of carbon sequestration.
c.
By recycling materials, the amount of biomass available for energy purposes is increased.
d.
All of the above
1. The correct answer is B. Conservation tillage practices help the soil erosion and also maintains soil nutrient levels.
Conservation tillage is termed as the tillage system which helps to conserve energy, soil, water through retention of crop residue and reduction of tillage intensity.
2. Correct answer is A. Aquifers 1 and 3 may result in a reduced river flow. Aquifer is termed as the underground layer of rock fractures, water-bearing permeable rock.
Hydrogeology is termed as study of water flow which is found in aquifers.
3. Correct answer is A. Recycling materials helps decrease the amount of new material which are taken from environment.
Most household can be recycled. Some other examples which are recycled include textiles, plastics, organics, and metals. Metals such as drinking bottles and food cans which are made from steel and aluminium can be recycled.
