How is biodiversity a measure of health?? some one please help me
KIM [24]

Answer:

Biodiversity is a measure that combines richness and evenness across species. It is often measured because high biodiversity is perceived a synonymous with ecosystem health. Diverse communities are believed to have increased stability, increased productivity, and resistance to invasion and other disturbances.Biodiversity gives resilience from the microbes that contribute to the formation of the human biome to the genes that help us adapt to stress in the environmentsupports all forms of livelihoods, may help regulate disease, and is necessary for physical, mental, and spiritual health and social well-being.

Mitochondria in animal cells, while mitochondria and chloroplast in plant cells most closely resembled prokaryotes.

<h3>What do you mean by endosymbiotic theory?</h3>

This theory states that organelles such as mitochondria and chloroplast in eukaryotic cells were once prokaryotic microbes.

These organelles when occupied in prokaryotes divide by binary fission. But they become a part of the eukaryotic cell now and result in a symbiosis relationship between each other.

Therefore, Mitochondria in animal cells, while mitochondria and chloroplast in plant cells most closely resembled prokaryotes.

Identify three environmental influences on microbial growth. How does each affect microbial distribution?
Alenkinab [10]

Answer:

1.Temperature

2.Moisture

3. PH: acidic or basic concentration

Explanation:

Different microorganism grow at different temperature. For example, many human-disease-causing microbes have an optimum temperature of 37C, and most of the bacteria do not grow at temperature higher than 45C. This means that any temperature lower than 45C will favor the growth of certain bacteria while higher temperature may cause death or reduction in the population of most. Hence, the effect of temperature on these organisms.

Water is required to dissolve the cell substances in microorganism just like higher animals.  while some can survive under an extremely dry condition, most can't and this could result in death or reduction in population.

PH, a measure of the hydrogen concentration in a solution for most microorganism is between 6-8, too much of acid or base could disrupt the activities of these organisms and a maintained range ensure an optimal survival.

What do you learn about global water supplies? <br> pasagot po ng tama thank uu
max2010maxim [7]

Answer:

1. Most water we use goes to agriculture

Agriculture places significant pressure on the world's fresh water, accounting for nearly 70% of all water withdrawals. That number can rise to more than 90% in countries like Pakistan where farming is most intensive. Unless substantial efforts are made to reduce food waste and increase the water-use productivity of farming – to get more “crop per drop” – water demands in the agricultural sector are projected to increase in the coming years to keep up with population growth.
