Answer:
Explanation:
Industrialization and use of combustible engines for daily life activities by humans has led to the production and release of a large amount of greenhouse gases (such as CO₂, N₂O, CH₄ and CFC) into the atmosphere-which prevents a large amount of heat produced from the earth moving to space.
The burning of fossil fuels by combustible engines (from cars, trains, power generating sets e.t.c) widely used by humans has led greatly to this climate change. Trees that help absolve a large amount of the most abundant man-made greenhouse gas (CO₂) has not been massively planted around, which indirectly worsens the case of global warming. Trees would have absorbed/breath in the CO₂ while producing/breathing out O₂ that could help cushion the effects of global warming.
The cardiac muscle is only in the heart because it has special characteristics such as being able to make sustained contractions, coordinated movement, and rapid conduction. Hope this helps!
Explanation:
Each has one chlorin ring- chlorin is a form of porphyrin.
Chlorophylls are comprised of a ringed molecule, chlorin, a hydrogenated form of porphyrin which contains a magnesium ion at the center, bonded to four atoms of nitrogen. Varying types of Chlorophyll have side chains, which affect the absorption spectrum of the molecule for instance A has a methyl group bonded to the C7 position, while B has an aldehyle (CHO) group at this location.
Embedded within the thykaloid membrane of chloroplasts, chlorophyll a and B mainly absorb orange-red and violet-blue wavelengths and convert light energy into chemical energy for the process of photosynthesis. This occurs in the light-dependent reactions of photosynthesis, within chloroplasts of plants. The range of wavelengths absorbed by a pigment is its absorption spectrum while it reflects those outside of this range. Plants appear green as this region of light is reflected by the pigments.
