water
iodine
air
calcium
Among these, it is water which is a compound.
A compound is a substance which is made up of two or more different elements. Apart from this, the different elements in a compound are bound by a chemical bond in a fixed proportion.Water is a compound which is made up of two different elements which are hydrogen and oxygen. The chemical formula of water is H2O. Also, the proportion of hydrogen to oxygen in water is definite which is 2:1. Among other options, iodine and calcium are elements. As far as air is concerned, it is a mixture of various gases not a compound. So, correct option is water.
Answer:
organisms need ENERGY to conduct essential life activities
Explanation:
organisms need energy to digest, use the restroom, eat, even standing up requires energy!
Respiration
Photosynthesis
Homeostasis
Reproduction
Answer:
Homeostasis
Explanation:
Homeostasis means that there is an equilibrium in the cell. Moving materials either in or out helps to ensure that both inside and outside the cell are equal.
Moving substances into and out of cells helps maintain homeostasis, which is a state of steady internal conditions.
The process of moving substances into and out of cells helps maintain homeostasis. Homeostasis is a state of steady internal conditions maintained by organisms. Cells need to regulate what substances enter or leave them in order to keep their internal environment stable. This is instrumental for their proper function. For example, nutrients need to be absorbed while waste products need to be expelled.

The egg
Explanation:
Another animal had a egg and it evolved into a chicken egg when it cracked it had a baby chicken.
Answer: They may have had an important function in the past.
Explanation:
have contributed to an
increase in the survival rate
of the human population.
How have these factors
contributed to the
homeostasis of the
population within its
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.
