Plastic is a non-biodegradable and non-point source of pollution because it cannot be broken down into degradable materials by micro-organisms. It comes from man-made substances and industries therefore, it is non-point pollutant.
What is Plastic?Plastic is a non-biodegradable and non-point pollutant. Because, the enzymes in the microorganisms cannot break down the waste into bio-degradable materials as microbes cannot recognize the bonds that hold these polymers together. Eventually, the polymers in plastic may break down, perhaps after hundreds of years. But after a long time, the damage is already done to the environment.
Nonpoint source of pollution comes from oil, pet waste, herbicide, bacteria, sediment, and any other contaminant that ends up on the ground naturally or from human activity.

What a types of organisms do lactic acid fermentation? Summarize this process
Answer: In lactic acid fermentation, pyruvate from glycolysis changes to lactic acid. This type of fermentation is carried out by the bacteria in yogurt, and by your own muscle cells. In alcoholic fermentation, pyruvate changes to alcohol and carbon dioxide. This type of fermentation is carried out by yeasts and some bacteria.
Explanation: Found on Flexbooks.
Lactic acid fermenting bacteria is Lactobacillus, though other bacteria and even yeast are sometimes used.
Lactic acid fermentation is a metabolic process by which glucose or other six-carbon sugars are converted into cellular energy and the metabolite lactate, which is lactic acid in solution.What is lactic acid?Lactic acid is mainly produced in muscle cells and red blood cells.It forms when the body breaks down carbohydrates to use for energy when oxygen levels are low. When body's oxygen level might drop include: During intense exercise lactic acid is formed.What is fermentation?Fermentation is a chemical process by which carbohydrates, such as starch and glucose, are broken down anaerobically. Fermentation has many health benefits and is used in the production of alcoholic beverages, bread, yogurt, sauerkraut, apple cider vinegar and kombucha.

In what ways do plants use energy
Answer:
Plants use energy in multiple ways. One way they use energy is to move. Many don't realize that plants move because their exact position does not change. However, plants do shift in order to face the sun and get more light. Additionally, plants grow. For plants to get taller and larger they need to use energy.

True or False
Answer:
False
Explanation:
Question 1: Some cells produce and secrete high levels of digestive proteins. Which organelles would you expect to be abundant in those cells, and why? Question 2: Explain how active transport helps a nerve cell maintain its resting potential. Question 3: The Atlantic cod is a common fish of the Atlantic Ocean that must drink seawater to meet its water needs. Explain how active transport helps the Atlantic cod maintain homeostasis with regard to the balance of sodium and chlorine ions, which are abundant in seawater. ( Will Mark Brainliest). No Nonsense Answers.
Answer:
q1 : ribosomes because they are responsible for protein synthesis
q2 : by transporting potassium ions into the cell and sodium ions out of the cell maintaining a concentration gradient
q3 : seawater contains a high concentration of sodium and chlorine ions that the Atlantic cod gets rid of by actively transporting them out of its body

Identify organelles in a plant cell.
The organelles in the plant cell that are shown in the image are: A: Chloroplast, B: Vacuole, C: Cell wall and D: Endoplasmic reticulum.
A: Chloroplast - This organelle is responsible for photosynthesis, the process by which plants convert sunlight into energy and produce glucose. Chloroplasts contain chlorophyll, a pigment that captures light energy.
B: Vacuole - The vacuole is a membrane-bound sac filled with fluid, primarily containing water and various dissolved substances. It plays a role in storing nutrients, waste products, and maintaining turgor pressure in plant cells.
C: Cell Wall - The cell wall is a rigid outer layer found in plant cells, bacteria, fungi, and some protists. It provides structural support and protection for the cell, helping maintain its shape and integrity.
D: Endoplasmic Reticulum (ER) - This organelle is involved in the synthesis, folding, modification, and transport of proteins and lipids. It can be rough (with ribosomes on its surface) or smooth (lacking ribosomes). The rough ER is involved in protein synthesis and modification.

You push on an object with an applied force. What is the "reaction" force to your push?
the object being pulled by Earth
the object moving forward
the object pushing back on you
the object being lifted up
Answer:
the object pushing back on you
Explanation:
i put b in my test and it was wrong
and did it again and got it right
According to Newton's third law of motion, forces always act in equal but opposite pairs. Another way of saying this is for every action, there is an equal but opposite reaction. This means that when you push on a wall, the wall pushes back on you with a force equal in strength to the force you exerted.
The answer would be:
The object pushing back on you.

What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Which one is the odd man out?
leaf of a plant
horse muscle
blood
sugar
Answer:
LEAF OF A PLANT .
Explanation:
Among the given options, The odd one out is sugar. Sugar is a type of carbohydrate that is used for energy.
Leaf of a plant: A leaf is a green organ of a plant that is responsible for photosynthesis.
Horse muscle: Muscle is a type of tissue that is responsible for movement.
Blood: Blood is a fluid that circulates through the body and carries nutrients, oxygen, and waste products.
Sugar: Sugar is a type of carbohydrate that is used for energy.
Sugar is the only one of these four that is not a living organism. The other three are all living organisms: the leaf of a plant, a horse muscle, and blood.
Here is a more detailed explanation of why sugar is the odd one out:
Leaf of a plant: A leaf is a living organism because it is made up of cells that are able to carry out the basic functions of life, such as respiration, photosynthesis, and growth.Horse muscle: A horse muscle is a living organism because it is made up of cells that are able to carry out the basic functions of life, such as respiration, contraction, and growth.Blood: Blood is a living organism because it is made up of cells, such as red blood cells and white blood cells, that are able to carry out the basic functions of life, such as respiration, transport, and immunity.Sugar: Sugar is not a living organism because it is a molecule that is made up of carbon, hydrogen, and oxygen atoms.
