Answer:
C. A chlorine breaks off and forms a free radical
Explanation:
When CFCs are exposed to high levels of UV radiation in the atmosphere, the CFC molecule breaks into chlorine and forms free radicals.
These free chlorine radicals then reacts with ozone molecules and breaks the ozone atom (O3) to form chlorine monoxide and oxygen (O2) molecule.
CFCs are main cause of ozone depletion in the atmosphere.
Hence, the correct option is "C".
Which statement about balancing selection is correct? View Available Hint(s) Hint 1.opened hint What is balancing selection, and how does it differ from other forms of selection?

Natural selection states that complex organisms evolved through random mutations alone. True or False?
Answer:
False.
Explanation:
This statement is false because organisms don't evolve - populations do. New gene variants (i.e., alleles) are produced by random mutation, and over the course of many generations, natural selection may favor advantageous variants, causing them to become more common in the population. However, because mutation rates are low relative to population growth in most species, mutation alone doesn't have much of an effect on evolution.

According to the graph, which statement below is true?
A. This enzyme works equally well at all temperatures.
B. This enzyme works best at 10 degrees Celsius.
C. This enzyme works best at 45 degrees Celsius.
D. This enzyme works best at 60 degrees Celsius.
The rate of enzyme activity is at its highest when the temperature is 45°C. Thus option C is correct.
What are the factors affecting enzyme activity ?The optimum temperature for most of the enzymes is between 25-35°C and above 50°C leads to destruction of enzymes
The rate also increases with increased enzyme concentration up to the saturation point
Enzymes work at their optimum pH. The rate of enzymatic reaction depend on substrate concentration.
The accumulation of the products decreases the activity of enzymes, as they combine with the active site of enzymes by forming a loose complex and inhibits the activity of enzymes.
Some chemical substances like co-factors, potassium ion (K⁺), manganese ion (Mn²⁺) can increases the enzyme activity.
water increases the reaction rate. Light increases the reaction rate in some enzymes but harmful radiation like UV rays and X-rays decreases activity.

Explanation:
Which axiom is used to prove that the product of two rational numbers is rational?(1 point) Integers are closed under multiplication. Integers are closed under division. Whole numbers are closed under division. Natural numbers are closed under multiplication.
Answer: Integers are closed under multiplication.
Explanation:
Rational numbers are numbers of the form:
a/b
such that a and b are integers.
The axiom: " Integers are closed under multiplication. "
Says that if we have two integers, x and y, then:
x*y is also an integer.
So if we have two rational numbers,
a/b and c/d
Such that a, b, c and d are integers, and we multiply them, we have:
(a/b)*(c/d) = (a*c/b*d)
the numerator is a*c is the product of two integers, so this is an integer by the previous axiom.
the denominator is b*d, also a product of integers, so this is an integer.
then (a*d)/(b*d) is the quotient of two integers, then this is a rational number.
Answer:
the second one... Integers are closed under multiplication

Compare the characteristics of nitrogen fertilisers that are used for
broadcasting with a phosphate fertiliser that is insoluble in water??
Answer:
Nitrogen is mobile while phosphorus is immobile in the soil.
Explanation:
Nitrogen fertilizers are those fertilizers which provide nitrogen to the plants that is required by plants for the formation of amino acids. It increases vegetative growth of plant. Nitrogen fertilizer is highly mobile due to soluble in water and contaminated the underground water by leaching while phosphorus fertilizer are those fertilizer which provide second macro-nutrient i. e. phosphorus to the plants. Phosphorus is a vital component of energy molecule such as ATP. It is insoluble in water so it is immobile. Only 20 % of the applied phosphorus fertilizer is available to plants.

A recent viral video entitled "How Wolves Change Rivers" argues that the reintroduction of wolves to Yellowstone after a 70 year absence led to multiple changes in the biodiversity and ecology of the park. This is an example of a(n)
The options are missing from the question,below are the missing options;
a. Trophic cascade
b. Primary succession
c. Autograph
d. Eutrophication
e. Pioneer community
The correct answer to the question is option A.
TROPHIC CASCADE.
Trophic Cascade occurs when there is a series of significant difference/changes in the population size of organisms in the tropic level of an ecosystem.this change in trophic level occurs in a food chain and as a result of predators being in high trophic levels, they use the opportunity to indirectly promote the population of the organisms in the low trophic levels,they do so by ensuring that species that are at intermediate trophic levels are are in close watch or check.
This corresponds with the viral video of of how wolves change rivers featuring
the reintroductionn of wolves to Yellowstone after a 70 year absence which led to multiple changes in the biodiversity and ecology of the park.

A particular pea plant has one allele for a tall stem (T) and one allele for a short stem (t). By observing it, you can see that it has a tall stem as well as many other different traits. Using this example, explain the difference between phenotype and genotype. Which one can be observed? Which one helps to determine the other?
Answer:
phenotype is the physical make up of an organism. it is controlled by alleles found in the cells of an organism. dominant alleles overshadow the recessive alleles. the allele for tallness for example, is dominant to that for shortness. since alleles occur in pairs, this plant which is tall can either be genotype TT or Tt , two dominant alleles or one dominant allele and the recessive allele which overpowers the recessive allele hence making the plant appear tall. genotype is the genetic make up of an organism. this determines how an organism appears to look externally.
hence genotype determines phenotype.

It does the work of urine formation through 3 distinct processes.
-Ultra filtration( Small molecules are forced out of the selectively permeable membrane of the glomerulus into the Bowman's capsule under regulated pressure.these molecules are from the blood in the glomerulus brought in by the afferent arteriole.
- Selective reabsorption ( Useful molecule and iron such as glucose and sodium are reabsorbed back into the blood as the filtrate flows through the tubule(nephron)
-Tubular Secretion. ( Movement of molecules not filtered by the glomerulus during the initial stage of filtration back into the filtrate through the renal capillaries.

A scientist has been working for 15 years to develop a new type of plastic material, but she has not yet been successful. Which of the following
best explains why her work is still a success?
a
New ideas often develop from unsuccessful experimentation.
b
The original problem was not solved and can now be abandoned.
с
Most scientists require several decades of experimenting before achieving their goals.
d
The scientist has demonstrated that there are no new plastics for scientists to develop.
Answer:
a. New ideas often develop from unsuccessful experimentation.
Explanation:
The scientists' work would still be considered a success because new ideas often develop from unsuccessful experimentation. Many of today's famous inventions and celebrities failed at the start of their career. However, because they did not give up on their goal, they eventually succeeded. A few examples of those people are Bill Gates, Albert Einstein, and Michael Jordan.
Here is an influential quote, said by Michael Jordan, that I think accurately supports this topic of discussion:
"I've missed more than 9,000 shots in my career. I've lost almost 300 games. 26 times, I've been trusted to take the game-winning shot and missed. I've failed over and over and over again in my life. And that is why I succeed."
A scientist has been working for 15 years to develop a new type of plastic material but she has not been successful. Her work is still a success because new ideas often develop from unsuccessful experimentation.
What are the principles of scientific research?There are various principles that need to be followed when scientific research is being carried out. Methods of self-regulation and authority regulation are both extremely important for conducting scientific research.
They both need to be followed as no one is sufficient without another. The basic principle for scientific working which is required to be followed by all scientists is respect for the work, the integrity of the knowledge, honesty about the data and openness about their mistakes.
Scientific principles are required to be followed in every stage of scientific research, right from the formation of a hypothesis to the publishing of results.
Therefore, even if research is not giving any results it is successful new ideas develop from unsuccessful experimentation.

Answer:

2. The peanut butter is being added
to the cake by the chef - passive voice
3. The blue dress had been put on
display by the store assistant - passive voice
4. Karl gave a touching speech at his
graduation ceremony - active voice
5. Jacob's party will be attended by
everyone in town - passive voice
6. Fred played with a monkey during
his first trip to a zoo - active voice
Explanation:
In English language, the voice of a sentence can either be passive or active.
A sentence is said to be ACTIVE if the subject is performing the action (verb). Hence, the sentence is referring to the subject doing the verb's action directly. For example;
1. Phil went to a movie with his friends
2. Karl gave a touching speech at his
graduation ceremony
3. Fred played with a monkey during
his first trip to a zoo
These are examples of sentences (1,2,3) in active voice because the subjects are performing the actions in the sentence.
On the contrary, a sentence is in the PASSIVE VOICE when the subject is acted upon by the verb in the sentence. In other words, the subject becomes the receiver of the veeb's action. For example;
4. The peanut butter is being added
to the cake by the chef
5. The blue dress had been put on
display by the store assistant
6. Jacob's party will be attended by
everyone in town
The above examples (4,5,6) are all in passive voices because the subjects in the sentences are acted upon by the verbs.
