Nearly all life on Earth ultimately gets its energy from the sun, which gets "its"energy through nuclear fusion. <span>With the exception of hydrogen, all of the chemical elements needed for life were produced by nuclear fusion of lighter elements, either in the cores of stars or in the shock waves of supernova explosions.</span>
Answer:
Muscle fatigue is often reported by patients with Marfan syndrome although myopathy is not classically considered a component of Marfan syndrome [1, 2, 4, 6, 7]. In addition to apparent muscle underdevelopment, some patients report myalgia or cramps suggesting skeletal muscle involvement.
<span>Natural selection is what allows a population to adapt because the animals that adapt are the ones that mate and pass along their genes. Without natural selection, evolution or adaptation would not be able to occur.</span>
Answer:
The correct answer will be-
1. Evolutionary unity- DNA
2. specialized cellular modifications- plant cells have chloroplasts and large central vacuole.
Explanation:
<u>Case I
</u>
Evolutionary unity is a concept which explains that all the organisms possess some common structure or universal structure or molecules.
The best characterized evolutionary molecule is DNA molecule which took the role of genetic material in past and is passed on to the daughter cells and still is made up of the same components which are a five-carbon sugar, four types of nitrogenous bases and a phosphate group. This DNA molecule is present in almost every organism except for a few viruses.
<u>Case II
</u>
The specialization of the cellular components depends on the function a cell has to perform which became established in the population. The plant cells depended on the sunlight to prepare food for themselves which was done by the chloroplast organelle which is absent in the animal kingdom.
