Answer:
B: These organisms developed similar traits because their environments were at one time similar.
Explanation:
As per the given data the answer is correct.
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: carbohydrates is composed of amino acids
Explanation: carbohydrate functions as an energy giving food in the body. Examples are rice, casssava and maize. The molecular structure of carbohydrate is (CH20)n. Carbohydrate has three subtypes:
(1) Monosaccharides: They are simple sugar and consists of a number of carbons(C) which ranges from 3 to 7.
(2) Disaccharides: They are formed when two Monosaccharides undergo a dehydration reaction which is also known as condensation reaction. thanks
(3) Polysaccharides: They consist of a long chain of branched or unbranched
Monosaccharides Monosaccharides linked by covalent bonds.
Carbohydrates is not composed of amino acids but rather protein is composed of amino acids.
All living things need energy; it is a requirement for life. In a typical cell, ATP, the high energy molecule, is produced in the MITOCHONDRIA <span>in the presence of a sugar (glucose) and OXYGEN.
