Answer:
The minimum, maximum and average 2007 population of the cencus tracts in the city of Austin is (minimum)10883; (maximum) 8323732; (average 2007) 736677
Explanation:
Multicellular organisms e.g. man meet their needs through use of specialized systems that they have in their bodies. Examples of such include:
1. cardiovascular system composed of heart, veins and arteries which facilitate transport of nutrients to all parts of the body .
2. Skeletal system composed of bones, joints, ligaments and cartilage whose function is support and protection of the body.
3. Digestive system composed of mouth, esophagus, stomach , small and large intestines whose function is breakdown of food and absorption of nutrients.
Answer: from the mouth to stomach
Explanation: mechanical digestion takes place when the food travels down from the mouth to stomach. Chemical digestion occurs from the mouth to intestine.
Answer: Plastic Pollution
In 1950, the world produced more than 2 million tons of plastic per year. By 2015, this annual production swelled to 419 million tons and exacerbating plastic waste in the environment.
A report by science journal, Nature, determined that currently, roughly 11 million tons of plastic make its way into the oceans every year, harming wildlife habitats and the animals that live in them. The research found that if no action is taken, the plastic crisis will grow to 29 million metric tons per year by 2040. If we include microplastics into this, the cumulative amount of plastic in the ocean could reach 600 million tons by 2040.
Shockingly, National Geographic found that 91% of all plastic that has ever been made is not recycled, representing not only one of the biggest environmental problems of our lifetime, but another massive market failure. Considering that plastic takes 400 years to decompose, it will be many generations until it ceases to exist. There’s no telling what the irreversible effects of plastic pollution will have on the environment in the long run.
To graph this inequality, start with an open dot on -2.
We use an open dot because n is
greater than -2 but n is not equal to -2.
Next we draw an arrow to the right
to represent all numbers greater than -2.
I have graphed this inequality below too.
The graph below is my own work.
This should correspond to the first answer choice.
