The ozone layer in the stratosphere protects Earth from the sun's ultraviolet radiation. Where does the ozone come from?

Biology

Ozone is created when energetic photons from the sun such as the UV strikes a molecule of oxygen splitting the two atoms. The radical atom then bombards with another oxygen molecule and join to create an O3 complex called ozone. The rate at which the ozone is created is balanced by the rate at which it is destroyed by the same energetic photons.

Ans.

The codons show genetic codes, made up of triplet of nucleotides in DNA or RNA that code for specific amino acids. The different codes can code for a same a amino acid. When a substitutional mutation occurs in genetic material, it shows substitution of one nucleotide pair for another and leads to formation of a different codon.

The first mutation that leads to CAU to CAC, it will not show any potential damage as both CAU and CAC codons code for histidine amino acid.

The second mutation that leads to UGU to UGC will also not show any damage to protein as both of these codons code for cysteine amino acid.

The third codon, that results UCU to UUU will cause a potential damage to protein as UUU codes for phenyl alanine (an aromatic, non-polar amino acid) and UCU codes for serine (a polar amino acid).

Thus, the correct answer is 'option C).' as in a protein, substitution of serine with phenylalanine will lead to change in structure and function of that protein.

How do scientists uncover evironmental problems
aleksandrvk [35]

Answer:

Science has a central role in shaping what count as environmental problems. This has been evident most recently in the success of planetary science and environmental activism in stimulating awareness and discussion of global environmental problems. We advance three propositions about the special relationship between environmental science and politics: (1) in the formulation of science, not just in its application, certain courses of action are facilitated over others; (2) in global environmental discourse, moral and technocratic views of social action have been privileged; and (3) global environmental change, as science and movement ideology, is vulnerable to deconstructive pressures. These stem from different nations and differentiated social groups within nations having different interests in causing and alleviating environmental problems. We develop these propositions through a reconstruction of The Limits to Growth study of the early 1970s, make extensions to current studies of the human/social impacts of climate change, and review current sources of opposition to global and political formulations of environmental issues.

In operant conditioning, many complex behaviors are learned through shaping.<br> T/F
alekssr [168]
It is <u>true </u>that i<span>n operant conditioning, many complex behaviors are learned through shaping.
This means that you learn many new things through consequences that you experience. So, for example, when you're a kid, you are constantly being told not to touch a hot stove. But given that you are small and inquisitive, you still touch it and burn your hand. After that, you learn that touching something hot is going to hurt you, so you learn not to do it through a consequence.</span>
