I NEED THE ANSWER ASAP!!!!!!!! Wastewater is treated with chlorine to kill bacteria. However, chlorine can be toxic to certain fish that live in the ocean. Why does this most likely add to the cost of cleaning water?
Answer:
if they are dumping wastewater into the ocean your place isnt that smart now are they
the best thing to do is clean the water and use it for drinking water etc
cuz the fact that there is not alot of drinking water but we have to be carefull of how much water we turn into drinking water cuz if it all tuned into fress drinkable water the world would be so much lighter and the atmosphere would most likly not be able to support us or other lifeforms and if we did manage to live then we would need to become so much heaver so a normal person would go from 200 pounds to 500 or more easily so there are ristriction on how much we can turn into dinkable water but we have such less rn but it would be easy to calculate with the help of some math people
hope this helps you learn

Match the food item to its nutrient group. Your options are macronutrients and micronutrients
1. carbohydrates
2. calcium
3. fats
4. proteins
5. vitamins
6. zinc
Answer:
Macronutrients
- Proteins
- Carbohydrates
- Fats
Micronutrients
- Calcium
- Vitamins
- Zinc
Explanation:
Got it right on my test. Have a good day!
Carbohydrates, proteins, and fats are the macronutrients, whereas vitamins, calcium, and zinc are the micronutrients.
What are macronutrients?Macronutrients and micronutrients are two very essential nutrients that are required for the growth and development of the body. Macronutrients are nutrients required in large quantities in the body for its growth and development, and to perform various other body functions. Carbohydrates, proteins, and fats are the three main macronutrients found.
Carbohydrates are building blocks of monosaccharides and provide energy to the body whereas proteins are building blocks of amino acids and are required to build and repair tissues in the body. Fats are also the building blocks of fatty acids and are important for protecting organs and providing energy too.
Micronutrients, on the other hand, are nutrients required in smaller amounts, and are essential part of the body. Micronutrients include vitamins and minerals such as calcium, iron, and zinc.
Therefore, carbohydrates, proteins, and fats are the macronutrients, whereas vitamins, calcium, and zinc are the micronutrients.

Which biomes have 4 seasons?
Answer:
Temperate deciduous forests
Explanation:
Temperate deciduous forests are most notable because they go through four seasons: Winter, Spring, Summer, and Fall.
The temperate deciduous forest is a biome which possess four seasons.
What is a biome?An area categorized based on the species, which thrive in that location is known as a biome. The type of soil, temperature range, and the amount of water and light are unique to a specific place and form the niches for particular species, which permits the researchers to define the biome.
A biome, which is always changing is the temperate deciduous forest. It exhibits four different kinds of seasons:
WinterSpringSummer FallThe summers are warm and the winters are cold. These forests get between 30 and 60 inches of rain in a year. In this biome, precipitation happens year round. The common vegetation witnessed in this biome is broadleaf trees, perennial herbs, and mosses.
Thus, temperate deciduous forest is the biome, which exhibit four seasons.

Norman thinks that the brain function of students suffers when they receive less sleep. He predicts that students who get less sleep before an exam will receive lower test grades. To investigate his idea, he tests two groups of chemistry students. Group 1 receives four hours of sleep, while Group 2 receives the recommended eight hours of sleep the night before the exam. Both groups consume the same foods before testing. They then take the same exam in the same room. What experimental factors could have been a possible source of error in Norman's investigation?
A. the food students consumed before the exam
B. the amount of sleep students received before the exam
C. the grades students earned on their exam
D. the temperature and light of the testing room
A scientific _______ is likely to be used in a new area of science, but unlike other scientific ideas, it will not likely change over time. hypothesis law theory question
Answer:
Theory...I think..
Answer:
it is a law
Explanation:
A law is a fact and cannot be changed.
This is unlike other scientific ideas because, for example a theory can be changed many times, either because of new experiments or technology and that is not present in a law.

What Cellular Process breaks down this molecule into the energy-carrying molecule found in the cells of all living things?
Answer:
cellular respiration
Explanation:
Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP
Answer:
The citric acid cycle.
Explanation:
The molecule mentioned is glucose. Glucose break down occurs in both animals and plants as a way of deriving energy. Using the citric acid cycle otherwhise known as the krebs cycle it uses glucose to from ATP, energy for the cell. The citric acid cycle occurs in the matrix of the mitochondria. That is why mitochondria are known as the power house of the cell.
What are the characteristics of a scientific question
Answer:
A scientific question is a question that may lead to a hypothesis and help us in answering (or figuring out) the reason for some observation. Asking a scientific question is a part of the scientific method (which includes making an observation, asking the question, forming a hypothesis, testing it and accepting/rejecting/modifying the hypothesis). A good scientific question has certain characteristics. It should have some answers (real answers), should be testable (i.e. can be tested by someone through an experiment or measurements), leads to a hypothesis that is falsifiable (means it should generate a hypothesis that can be shown to fail), etc. For example, an observation that a passing car makes a lot of noise can prompt someone to ask "if there is some correlation between the speed of the car and the noise it generates", which can result in a hypothesis that at higher speeds more noise is generated. This can be tested by driving a car and measuring the noise level and these results can help us accept or reject or modify the hypothesis.

why are the leaves of desert plants reduced into thorns
The leaves of the desert plants are reduced to spines/thorns to help to prevent the loss of water by transpiration. Since in deserts, there is a scarcity of water, if the plants lose more water, they will not survive. Hence to prevent this such adaptations have been developed.
Answer:
The heat of the desert is hash so they are thorns so the predictors don't drink their water

explain the 1st and 2nd law of thermodynamics in terms of food chain, energy flow, pyramid of number and pyramid of energy
Answer:
First law of thermodynamics is the conservation of energy states that energy is not created and not destroyed but only can be stored.
Thermodynamics second law states that total entropy of a system increases from lower to higher system and some of the energy is always wasted during the work done.
In the food chain plants are the producers which accept light energy and stored in the form of chemical energy and energy flow to the herbivores and higher trophic levels in the chemical form only and no new energy is created in between the chain (Fisrt law of thermodynamics). Heat is generated during respiration by plants and animals (wasted energy) and entropy also increases with the increase in level of the pyramid of energy (Second law of thermodynamics).
