Answer:
Ozone holes have more ozone than usual.
Correct Answer
Ozone holes allow ultraviolet light to reach the Earth's surface.
Ozone holes don't have any ozone in them.
Chlorofluorocarbons make an ozone hole larger.
Explanation:
Ozone has been the atmospheric layer that protects the earth. It allows the ultraviolet rays to enter the earth, and there is one ozone hole due to the Chlorofluorocarbons. Thus, options B, C, and F are correct.
What is an ozone hole?An ozone layer is defined by the presence of the ozone gas that is present in the atmosphere of the earth. The ozone hole is the hole in the ozone layer that is due to the depletion of the ozone gas in the layer due to increased global warming and pollution.
The increased concentration of Chlorofluorocarbons (CFCs) generated from aerosols, air conditioners, and refrigerants have resulted in a hole in the ozone layer. This lead to increased exposure of the organism to the harmful UV radiations emitted from the sun.
Also, this has resulted in increased climatic changes because of the global warming and heating of the atmosphere due to the entrapment of the UV and Sun rays. This leads to various diseases including cancer and eye irritation.
Therefore, the ozone hole is due to increased Chlorofluorocarbons. options B, C, and F are correct.

a wave with a frequency of 2.364 has a wavelength of 10.4045. What is the speed?
a sound wave with a speed of 346 meters per second has a frequency of 30.025. What is the wavelength of this wave?
8.4 waves go by in 6.875 seconds. Calculate the frequency (per 1 second).
Answer: 4.4; 10,339; 0.145
Explanation:
F = c/L f = frequency, c= wave speed L = wavelength
1. 2.364 = 10.4045/c, c= 10.4045/2.364 = 4.4
2. 30.025 = L/346, L = 30.025*346 = 10,339
3. period of the wave 6.875/4 = 1.72 and f= 1/period = 4/6.875 = 0.145
6. Type of energy that can travel through space in the form of waves.

What is the main difference between active and passive sonar
Answer:
There are two kinds of sonar: One is passive sonar, and the other is active sonar. For passive sonar, we don't send sound waves but just receive them. By listening to these special sound waves, animals that communicate with these particular sound waves can be detected. By listening to the sound waves from engines of submarines or ships, we can locate them.
Also, other things that vibrates can be detected by passive sonar. Many threats on the sea are usually detected by passive sonar this way. Since passive sonar does not transmit any thing to the environment, it does no harm to other animals. Active sonar is a little different.
Besides having a receiver, active sonar also transmits sound waves. Active sonar works by transmiting particular sound pulse and measuring the length of time for the sound to be reflected back, then devide the time by 2 to get the time it takes for the sound pulse to reach the object

.. Which pair of organisms is most likely to have adaptations in common?
Answer: the 1st one
Explanation:
A grassland predator and prey, such as a cheetah and a zebra. Therefore correct option is (A).
What organisms have common adaptations?The pair of organisms that is most likely to have adaptations in common is a pair of organisms that share similar environmental pressures or ecological niches. Organisms that occupy similar habitats, have similar diets, or face similar challenges are more likely to evolve similar adaptations over time.
For example, predatory animals such as lions, tigers, and leopards have evolved similar adaptations such as sharp claws, powerful jaws, and keen senses to help them catch prey. Similarly, desert-dwelling animals such as camels, kangaroo rats, and fennec foxes have adaptations such as the ability to conserve water, tolerate heat, and dig burrows in sandy soil to survive in their arid environments.

which system controls the female reproductive system
Answer:
The reproductive system is controlled by the gonadotropins follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which are produced by the pituitary gland. Gonadotropin release is controlled by the hypothalamic hormone gonadotropin-releasing hormone (GnRH).
Explanation:
(Endocrine)
Flow
Explain why countercurrent flow met the goals and why parallel flow did not meet the goals.
Answer:
Fish utilise a counter-current system in order to maximise the amount of oxygen that can extracted from water. Water has a much lower oxygen content than air and as such fish need a much more efficient system that can extract a much higher proportion of oxygen from the surrounding water.
Explanation:
Counter flow created more movment and chaos, it made the molecules bump into each other more often, which makes it more likely that each individual partivle will go out of the pores. whereas parelel flow the particles move neatly along side one another

True
False
Answer:
False
Explanation:
It is false because inductive reasoning is a reasoning that is not based on observations but it is based on hear say,i.e what people say, what is read or news read e.t.. Therefore it is not observed. But the above us deductive reasoning because this is based on observations, theories e.t.c. it is based on what is seen or observed.
Answer:
True
Explanation:
Inductive reasoning is a method of reasoning in which conclusion are drawn on the premise of the evidence supplied. The evidence are the tools from which conclusions are drawn but not full assurance, of the truth of the conclusion.
It could also involve the individual's experiences and observations together with what are learned from others, this together help synthesize the general truth.

Do you think an advanced civilizations may exist in the universe? Why or why not?
Answer:
Many other planets throughout the universe probably hosted intelligent life long before Earth did, a new study suggests.
The probability of a civilization developing on a potentially habitable alien planet would have to be less than one in 10 billion trillion — or one part in 10 to the 22nd power — for humanity to be the first technologically advanced species the cosmos has ever known, according to the study.
"To me, this implies that other intelligent, technology-producing species very likely have evolved before us," said lead author Adam Frank, a professor of physics and astronomy at the University of Rochester in New York. [13 Ways to Hunt Intelligent Alien Life]
In 1961, astronomer Frank Drake devised a formula to estimate the number of extraterrestrial civilizations that may exist today in the Milky Way.
Adam Frank and co-author Woodruff Sullivan of the University of Washington were interested in the odds that intelligent aliens have ever existed anywhere in the universe. So they tweaked the famous Drake equation, coming up with an "archaeological version" that doesn't take into account how long alien civilizations may last.
Frank and Sullivan also incorporated observations from NASA's Kepler space telescope and other instruments, which suggest that about 20 percent of all stars host planets in the life-friendly, "habitable zone," where liquid water could exist on a world's surface.

Look at the following chemical reaction.
Which process is happening in the reaction that is shown?
A. Dehydration
B. Acidization
C. lonization
D. Hydrolysis
Answer:
Dehydration, sorry if its wrong
Explanation:
Hydrolysis is happening in the reaction. Hence the correct option is D.
Hydrolysis is a chemical process that involves the breaking down of a compound through the addition of water. During hydrolysis, a water molecule splits into hydrogen and hydroxide ions, which participate in the cleavage of the chemical bond within the compound, resulting in the formation of two or more new substances.
Hydrolysis reactions are found in various natural and synthetic processes. In the context of biomolecules, such as proteins, carbohydrates, and fats, hydrolysis plays a fundamental role in their digestion and utilization. In industrial processes, hydrolysis is also employed to break down complex molecules into simpler components.
Hence the correct option is D.
