A compound isolated from a biological source is subjected to chemical analysis. It contains carbon and oxygen in roughly equal a

mounts and hydrogen in an amount that is almost twice that of carbon. This compound does not take up iodine stain very well, indicating that its structure is densely packed and resistant to large molecules binding to it through noncovalent interactions. What is the likely identity of this compound?a. Monosaccharideb. Glycogenc. Starchd. Triglyceride

Answer:B (glycogen)

Explanation:

Starch is in the form of amylose and amylopectin has less branches than glycogen. Glycogen is more branched and more compact than amylopectin of starch. glycogen is composed of glucose units joined by alpha-1,4 links in the straight chain and alpha-1, 6 glcosidic linkages at the branch point. Iodine atoms can bind into the helices of starch and glycogen to form a starch-iodine or glycogen-iodine complex respectively. The helices of starch are longer than glycogen, and therefore can bind more iodine atoms. The is the reason why color produced by a starch-iodine complex(blue black) is more intense than that obtained with a glycogen-iodine complex.

<h2>Mitosis Process</h2>

Explanation:

  • Plant cells and animal cells undergo the same cellular processes during mitosis.
  1. The centrioles absent in the plant.
  2. Animals  cells have centrioles, to what delivers the shaft strands is one of the differences among plant and creature mitosis.
  3. The periods of mitosis and goes on in each stage is the equivalent aside from when it comes to how cytokinesis is practiced.
  4. <em>Plant cells separate the cytoplasm between the two new cores by framing a cell plate (new cell wall)between the cores.</em>
  5. Animals cells achieve this by shaping a cleavage wrinkle which is a squeezing in at the center of the<em> </em><em>cell until two new cells have been framed with cytoplasm and organelles for each  new nuclei.</em>

How do biotic and abiotic factors. Contribute to the health of an ecosystem ??? Please explain
sweet-ann [11.9K]

Answer: They do affect the health of an ecosystem.

Explanation: In an ecosystem there are many things that are biotic and abiotic. For an example: water is abiotic and plants/animals are all biotic, the water is not living but it keeps the ecosystem alive by quenching the thirst of the plants growing from the ground and the animals roaming around on the land. Dead animals and plants are not abiotic and they are now providing food for fungi and bacteria. Without the abiotic factors, it would be difficult for the biotic to survive.

hram777 [196]

Answer:

<em>The probability of forming a "Y" gamete is 50%. The probability of forming a "y" gamete is 50%.</em>

Explanation:

Mendel was an Austrian monk whose findings led to make the foundation of genetics. Hence, Mendel is known as the father of genetics. He formulated two laws based on the researches he made:

  • Law of segregation
  • Law of independent assortment

According to the law of segregation, alleles segregate independently at the time of gamete formation. There is an equal chance for a gamete to carry the dominant or the recessive allele.

Hence, the probability of a gamete carrying a 'Y' or a 'y" allele will be 50% each.
