Answer:
I and III
Explanation:
Acid deposition will decrease pH levels in lakes and rivers since it contaminates them and lowers their pH, and organisms may be affected by the increased acidity in their immediate surroundings, but aluminum has nothing to do with pH levels at all.
Hope thish elped!
Option I and III shows the problems of environmental indicators of acid deposition.
The following information should be considered:
The acid deposition should reduce the level of pH in terms of lakes and rivers as it contaminates also the organisms should impact when the acidity should be increased for the surroundings. But the aluminum does not have any relationship with pH levels.Therefore we can conclude that options I and III are correct.

Which statement correctly describes gravity?
A. a repulsive force that acts between all objects through contact
B. a repulsive force that acts between all objects without contact
C. an attractive force that acts between all objects without contact
D. an attractive force that acts between all objects through contact
Answer:
C. an attractive force that acts between all objects without contact
Explanation:
The force of gravity, first discovered by Isaac Newton, is one of the four fundamental forces. It is a force that is always attractive, and it is exerted between all objects that have mass. Also, the force is exerted even when the two objects are not in contact.
The magnitude of the force of gravity between two objects is given by
where
G is the gravitational constant
m1 and m2 are the masses of the two objects
r is the distance between the two objects

In certain rats, black fur is dominant over white fur, If two rats that are both heterozygous for fur colored are mated, what would their offspring be expected to have?
Answer:
Three different genotypes and two different colors
Explanation:
Because both rats have heterozygous genes, meaning they have 2 different alleles, ex: "Yy") The offspring can have different genotypes and colors because the parents have heterozygous genes.
hope this helps!
The offsprings of the cross between two heterozygous rats will have the following genotypes: BB (black), Bb (black) and bb (white).
According to this question, a gene coding for fur color in rats is involved. The allele coding for black fur (B) is dominant over the allele for white fur (b). If two rats that are both heterozygous for fur are crossed i.e. Bb × Bb, gametes B and b will be produced by both rats. Using this gamete in a punnet square (see image), the following offsprings will be produced: BB, Bb and bb. BB - black offspringBb - black offspringbb - white offspringTherefore, the offsprings of the cross between two heterozygous rats will have the following genotypes: BB (black), Bb (black) and bb (white).Learn more at: https://brainly.com/question/3712307?referrer=searchResults

20. A research company wants to design a new type of artificial heart valve that will be less likely to be rejected by a person's immune system. Which step in the design process should the company perform before building a prototype of the heart valve?
A. Find test subjects for the new heart valve.
B. Conduct research on existing artificial heart valves.
C. Determine how to manufacture the new heart valve.
D. Evaluate the performance of the artificial heart valve.
Answer:
C. Determine how to manufacture the new heart valve.
I think it seems a little obvious (I'm probably wrong)because obviously before doing something important your going to think about how to do it first.
The step in the design process that should the company perform before building a prototype of the heart valve is to determine how to manufacture the new heart valve. Thus, the correct option for this question is C.
What is meant by a Prototype?A prototype may be defined as a sample, model, or liberation of a product that is significantly built in order to test a concept or process. This term is used in a variety of contexts, including semantics, design, electronics, and software programming.
A prototype is typically utilized in order to determine a new design to increase precision by system analysts and users. If an organization or individual wants to design any type of structural and functional unit, they must require to know its actual mechanism of it.
Then they are allowed to manufacture the concept with regard to their discovery. So, a research company requires to demonstrate how to manufacture the new heart valve with the help of a prototype.
Therefore, the correct option for this question is C.

Answer:
1. B
2. C
3. A
Explanation:
1. Most of the carbohydrates in the foods you eat are digested and broken down into glucose before entering the bloodstream. Glucose in the blood is taken up into your body's cells and used to produce a fuel molecule called adenosine triphosphate (ATP) through a series of complex processes known as cellular respiration.
2. Fats are known as being a long term energy source, and the fat on your body is used a "cushioning" for your bones.
3. To break a protein down into its amino acids you will need enzymes. Enzymes are biological molecules (proteins) that act as catalysts and help complex reactions occur everywhere in life.

Which of the following statements BEST describes photosynthesis?
a. Photosynthesis uses light energy to convert glucose and oxygen to carbon dioxide and water.
b. Photosynthesis uses light energy to convert glucose and carbon dioxide to oxygen and water.
c. Photosynthesis uses light energy to convert carbon dioxide and oxygen to glucose and water.
d. Photosynthesis uses light energy to convert carbon dioxide and water to glucose and oxygen.
Answer:- D
Photosynthesis used light energy to convert carbon dioxide and water into glucose and oxygen
The statement that best describes photosynthesis is statement d. As it converts carbon dioxide to glucose and oxygen.
Photosynthesis uses light energy to convert carbon dioxide and water to glucose and oxygen.During photosynthesis, plants, algae, and some bacteria convert light energy into chemical energy, stored in the bonds of glucose molecules.
The process involves the absorption of light by pigments called chlorophyll, which are present in the chloroplasts of plant cells and other photosynthetic organisms. Chlorophyll uses the light energy to drive the conversion of carbon dioxide and water into glucose and oxygen in a process called the Calvin cycle.
Thus, the correct option is statement D.

what was the problem with reusing contaminated water from other parts of the mill to extinguish the coke fires? From the book ‘When smoke ran like water’
Answer:
1. The problem with that was that the already poisonous water was made worse after using it to quench the flames from coke production.
2. It contaminated the soil, making it difficult for plants to grow.
Explanation:
As the author described the last stages of coke production, she explained that water was needed to quench the very hot flames from coke production. A 'bright fellow' suggested using dirty water from other parts of the mill to quench the flames from the coke production. The problems with this were;
1. The already contaminated water was made worse after it was used to quench the flames from coke.
2. Mrs. LaMendola noted that she was unable to grow her tomatoes in the path where the plumes from the oven ran. So the contaminated water negatively affected the soil.
The problem that should be already poisonous water is also made worse when it quenches the flames at the time when the production of the coke should be done.
Also, it contaminated the soil also it is difficult for growing the plants.
The problem of reusing contaminated water:Since the author explained the last coke production stage so here the water required to quench that it should be very hot flames arise from the coke production. Also, the contaminated water should be worse whenever it is used for quenching the flames. Also, the contaminated water does not positively impact the soil.

Once pollen lands on the stigma, it forms a pollen ____________________ down through the long_____of the pistil [the female reproductive part] into the flower's ______– which contains ovules. fill in the blank
Answer:
1. Pollen tube
2. Style
3. Ovary
Explanation:
This process is describing the process of POLLINATION, which is the transfer of pollen grains from the anther of a male flower (androecium) to the stigma of the female flower (gymnoecium). After pollination i.e. the pollen has landed on the sticky stigma, the pollen grows out a tube called POLLEN TUBE.
The pollen tube extends through the STYLE of the female flower called PISTIL to the OVARY. The ovary is the reproductive part of the female flower that produces the ovules, which the sperm in the pollen is about to fertilize.
