Answer AND Explanation:
Fossil fuels are substances that are combusted to provide energy. They include coal, natural gas and oil. Nitrogen(IV) oxide is a byproduct of all fossil fuel combustion that contribute to acid rain and ground-level ozone. Nitrogen (IV) oxide can burn lung tissue making people more susceptible to asthma, bronchitis, and other chronic respiratory diseases. When gases like sulphur (IV) oxide and nitrogen (IV) oxide mix they form acid rain and other precipitation when dissolved in water. Acidic precipitation increases the acidity of lakes and streams, which can be harmful to fish and other aquatic organisms.
Excess production of CO2 by industries results in green housse effect which causes global warming. The gases are also poisonous to the respiratory system causing breathing difficulties, eye irritation and headache.
Answer:
This question lacks options, options are: A) Heterochromatin and euchromatin
B) Uniform in the genetic information they contain
C) Separated by large sketches of repetitive DNA
D) Each void of typical protein-coding sequences of DNA
E) Void of introns.
The correct answer is A.
Explanation:
The chromatin or substance that makes up the nuclei of cells and that results from the interaction of DNA with histonic and non-histonic proteins and RNA; it can present different degrees of packing or contraction. When chromosomes are stained with chemicals that bind to DNA, densely stained regions and less densely stained regions appear. Heterochromatin are segments of the chromosome that stain strongly and remain visible, practically, during the entire cell cycle. There are few genes in these regions and therefore low transcriptional activity. They are supercondensed regions. Euchromatin are segments of the chromosome that are not visible during telophase and interphase, only in metaphase. It corresponds to regions that are less compact and in which there is a higher gene density.
Answer:
I intentally had an incorrect answer the right answer is subjective in case anyone needs it not bias its subjective. Explanation:
Answer:
embryos (the organisms early stage foetal development )
<em>Energy transformation</em>, also known as <em>energy conversion</em>, is the process of changing energy from one form to another. In physics, energy is a quantity that provides the capacity to perform work (Ex: Moving a heavy object from one place to another) On top of that, being convertible, according to the law of conservation of energy, energy is transferable to a different location or object, but it CANNOT be created or destroyed.
When it comes to transforming electrical energy to mechanical energy, A generator converts mechanical energy into electrical energy, while a motor does the opposite. A motor converts electrical energy into mechanical energy. Both devices work because of electromagnetic induction, which is when a voltage is induced by a changing magnetic field.
P.S - After doing some searching, I have found something that should help you, if what I said is confusing or not helpful to you at all. This website has helped me on many occasions and is a very helpful and valuable tool.
