Ozone definitely protects us from various harmful radiations and prevent the direct entry of UV rays falling on Earth. There is a case in which if ozone is present at the ground level it is considered as a pollutant. the correct answer is option C.
What is the hole associated with the ozone layer ?It is the black hole that is continuously rising and getting bigger in size though the more study about it is still unsolved.
Ozone high in Earth's atmosphere protects from the sun's dangerous radiation. But on the ground level, ozone is definitely an air pollutant that spoils people and plants. Ground-level ozone formed when nitrogen oxides along with the volatile organic compounds reacts to each other in sunlight and more hot temperatures.
Ozone at ground scale is a harmful air pollutant because of the effects on people and the related environment and it is main ingredient in “smog."

Which of the following bones are considered to be the MOST proximal?
metatarsals
clavicle
ulna
olecranon
Answer:
Of the group of bones mentioned, the most proximal is the clavicle, which is part of the shoulder girdle.
Explanation:
Proximal is a reference term used in anatomy to indicate the structures that are closest to the center of the body.
The bones mentioned -clavicle, olecranon, ulna and metatarsals- are related to the function of the limbs. The clavicle is the closest bone to them, located between the neck and the thorax, on each side of the midline of the body.
Regarding the other options, other bones are distal, as they move away from the center of the body. In order from less distal to more distal they are found:
Olecranon, which is a bone eminence of the ulna, in the upper limb. Ulna or cubitus, which is part of the bones of the forearm. Metatarsals are the bones that form part of the foot.Why does Earth get more energy from the sun than from all the other stars in the universe combined?

Which among the following mineral groups, if any, contain silicon: halides
carbonates or sulfides? Explain.
Answer:
The correct answer is: none of these mineral groups contain silicon.
Explanation:
The only minerals that contain silicon are the Silicates, for example, SiO2 (silica).
Halides are minerals that consist of a combination of elements from the seventh group that can form salts (like fluorine or chlorine), with other elements such as calcium and sodium. For example: NaCl (sodium chloride).
Carbonates are compounds that contain carbon and oxygen, for example, CaMg(CO3)2 (dolomite).
Sulfides consist of sulfur with another element. For example: ZnS (zinc sulfide).
The zika virus was first identified in Uganda in 1947. The virus is transmitted from person to person by a bite from a mosquito. It is commonly carried by the Aedes mosquito which is prevalent throughout Central Africa. The virus has more recently spread to the Americas (South, Central, and now North) and is expected to spread to Europe. There is a concern that the virus may reach epidemic proportions. Zika virus is related to yellow and dengue fever. Common symptoms are low grade fever and a distinctive skin rash and other symptoms include vomiting, headache, and muscle and/or joint pain. Pregnant women should avoid traveling to areas known to have zika virus present because the virus is known to cause microcephaly and developmental difficulties related to the central nervous system. Based on the paragraph above, class discussions, and other VALID (be careful with your selection of e-materials! CDC – Center for Disease Control is a good place to start) sources of information please answer the following questions.
1. State a reason why the virus has spread to the Americas and likely to spread to Europe.
2. Define the term microcephaly.
3. What bones of the fetal skull would be affected by zika? Specifically, what area of the CNS is not fully developed in microcephalic individuals.
Answer:
1. It is a highly contagious disease transmitted from person to person and thereby it is expected that infected persons carried the virus to America
2. Microcephaly is a serious birth defect where a baby’s head is much smaller than expected.
3. Occipital bone. CNS malformations: ventriculomegaly, parenchymal and periventricular calcifications and cortical migration anomalies
Explanation:
The Zika virus (Flaviviridae) causes a contagious disease and it is transmitted by Aedes mosquitoes, which are also the main vectors of the dengue virus. Microcephaly is a condition where the baby’s brain has not developed properly during pregnancy, and it has been shown that this birth defect is associated with the Zika virus. During 2015 in Brazil, the incidence of infants with microcephaly born from mothers that contracted this disease during pregnancy was higher, thereby suggesting an association between both conditions. Baby health problems associated with Zika infection include microcephaly (skull partially collapsed), joints with limited motion, etc.

Warm-Up Activity - Scenario: You are on a desert island. Alone. You must survive. The island has only one food source
that you've found: pineapples. It takes you 2 hours to harvest and cut up 1 pineapple (you have no knife!). You also want
to build your shelter. Each piece takes you 3 hours to build.
You have only 12 hours of sunlight and need to complete your tasks by sundown.
How will you spend your hours? Record your decision on your student notes.

1. Think back to the Warm Up activity. Why did you spend your hours the way you choose?
2. Whatlimits did you face? What tradeoffs did you make?
3. How does scarcity (limited resources) affect our economy and ability to produce?
Ce
Answer:
Explanation:
first day at the desert most of my hours will be spent making shelter for safety and then in the evening hunting is done for food.
Pineapple has an alternative way of opening without knife, which is to hit and roll on the ground severally exerting little force this allow the hard shell to be loosely packed and can be easily removed with hands from each box on the pineapple body.
The best way to maximize time is to do the most important and tedious work first.
Having limited tools to work with because it is a desert is a major challenge
Scarcity have put some industries on hold, many could not produce in large quantities because of Scarcity. The available resources is what is shared among many which makes its unavailable.
It affects the economy in terms of production and expected yield and return, it also affects people's standard of living.

Students in a science class visited four local ecosystems. The students observed the species present in each ecosystem and recorded their observations in the table.
Based on these observations, which ecosystem is likely to be the least sustainable?
A.Ecosystem 1, because it has the fewest species
B.Ecosystem 2, because it includes both aquatic and terrestrial species
C.Ecosystem 3, because it has few predators
D.Ecosystem 4, because it supports many animals
the answer is A
this is because in ecosystem 1 there are only predators and no other species are observed. therefore predators have less food to eat thus they will die of hunger or move to another ecosystem
This is because in ecosystem 1 there are only predators and no other species are observed. therefore predators have less food to eat thus they will die of hunger or move to another ecosystem.
What is Ecosystem?
An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life.
Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. Biotic factors include plants, animals, and other organisms. Abiotic factors include rocks, temperature, and humidity.
Every factor in an ecosystem depends on every other factor, either directly or indirectly. A change in the temperature of an ecosystem will often affect what plants will grow there, for instance.

what is a CER please help !!!!!!!
Answer:
Claim-Evidence-Reasoning
Explanation:
hope it helps
Answer:
CER(S) Stands for Claim, Evidence, Reasoning, Science
Explanation:
The 1st part of CER(S) is a CLAIM. A claim is a simple, single sentence that answers a question. Your claim is a statement about what you believe to be true about that question. Your claim must be accurate, clear, and exact. Your claim should be the first sentence in your explanation. Your claim should ONLY answer the question – do not explain your answer at this point.
The 2nd part of CER(S) is EVIDENCE. Evidence consists of data and/or results that can be used to support the claim. Evidence must be explicitly stated in sentence form and cannot merely be referenced. To adequately support a claim, the evidence must be appropriate (relevant to the question) and sufficient (enough provided to be convincing).
The 3rd part of CER(S) is the REASONING. Reasoning ties the evidence to the claim and explains why the evidence supports your claim. In this section you discuss why the evidence that you provided is important and relevant to your claim.
The 4th and final part of CER(S) is the SCIENCE. Your teacher may not ask you to provide the supporting science for every CER(S) question – that is why the S is in parentheses. If you are asked to provide the science that supports your claim, then you need to discuss the relevant science and how it supports your claim.
Which products do not have scientific studies supporting their claims to be beneficial when used?
A. Cofactors and coenzymes to support enzyme function
B. Lactase enzymes used in milk sugar digestion
C. Enzyme that aids in the digestion of oligosaccharides
D. Enzymes to promote immune system function
