Which of the following questions would BEST
determine whether a plant is undergoing the
Calvin cycle?
A. Is NADPH being produced?
B. Is oxygen being produced?
C. Is glucose being produced?
D. Is ATP being produced?
Answer:
C
Explanation:
Glucose is the end result of the calvin cycle. It is not Oxygen, NADPH, or ATP because those are produced in the light reactions.
Is glucose being produced? is the question which will best determine
whether a plant is undergoing the Calvin cycle.
The Calvin cycle is known s the light independent or dark reaction which
takes place during the process of photosynthesis by plants. The final
product for this cycle is Glucose.
Other compounds such as NADPH, ATP and oxygen are all formed during
the light dependent reactions which is why asking if glucose is produced is
the most appropriate choice.

What key adaptation allowed the ferns to be successful and populate more areas than the bryophytes?
Answer:
Possession of root, leaves and vascular/conducting tissues
Explanation:
Ferns and bryophytes are regarded as lower plants in botanical studies. Bryophytes have been in existence prior to the appearance of ferns. BRYOPHYTES are a group of non-vascular plants i.e. lack conducting tissues such as xylem, phloem etc. They include misses, liverworts and hornworts. Ferns, on the other hand, belong to a group of vascular plant species called PTERIDOPHYTES.
However, in terms of population and domination of the Earth, ferns are believed to be more successful than their counterparts (bryophytes). This is primarily because of the possession of true roots and vascular tissues like xylem (for conducting water), phloem (for conducting sugars) by FERNS making it easily adapted to life on land.

Histones are small proteins with a strong positive charge at physiological pH. They are found in the nuclei of eukaryotic cells and package DNA into nucleosomes, the fundamental structural units of chromatin. Based only on this description, what two forms of chromatography could you use, one after the other, to separate histones from other cellular proteins? Explain your reasoning.
Answer:
Two modes of chromatography that could be used over and over, based on characteristics of histones throughout the issue, are:
Size-exclusion Chromatography Ion exchange chromatographyExplanation:
Using size exclusion chromatography:A stationary step, consisting of such a polymeric material with numerous pores of various sizes. The larger proteins would travel further as the solvent system comprising the analytes flows through the paper chromatography and therefore will be separated first. That was because their greater size does not in itself allow the pores found in the polymer to get trapped. Tiny proteins such as histones, and on the other hand, can pass slowly across the process to have been eluted later.
Using Ion exchange chromatography:As even the histone properties at biological pH are strongly positively charged, through the use of highly reactive particles as when the stationary step will allow histones to connect to themselves and now all the proteins, as well as favorable proteins that are poorly absorbed, would be eluted. Many positively charged molecules, that aren't as highly charged at around the same pH as histones, will stay throughout the stationary step, however, based on whose net charge, should flow independently of histones.
The two classes of chromatography techniques include size-exclusion and ion exchange chromatography.
What are size-exclusion and ion-exchange chromatography?Chromatography is a technique used in molecular biology laboratories to separate biomolecules.
Size exclusion chromatography is a technique capable of separating biomolecules according to size by using filtration in a gel. Size exclusion chromatography is a technique capable of separating biomolecules and ions according to their affinity to a given ion exchanger.In conclusion, the two classes of chromatography techniques include size-exclusion and ion exchange chromatography.

Compare the exoskeletons of two invertebrates: a grasshopper (Arthropod) and a clam (Mollusca). How do they differ in relation to support and movement?
Answer:
Mollusca: Unsegmented exoskeleton, with no appendixes articulated to them. This skeleton has a calcareous origin. Arthropoda: Segmented exoskeleton, with different appendixes articulated to them, which develop different functions. This skeleton has a chitinous origin.Explanation:
Clams are bivalves. Their calcareous exoskeleton has two valves dorsally articulated to each other. They do not articulate with any appendix, although. These animals also have a foot, a small head, and a developed mantle cavity. The valves are convex, oval, and unsegmented. They are composed of three layers: periostracum, prismatic, and pearly. En the dorsal portion of each valve, there is a bulge called the umbo, which is the oldest part of the valve. The articulation has some teeth-shaped structures that are intercalated, maintaining the valves together and fixed. Grasshoppers have a chitinous exoskeleton divided into three principal segments or regions that allow their movement: head, thorax, and abdomen. The head is orientated in such a manner that their feeding apparatus is heading down. Also, the head segment has composed eyes and antennae. The thorax is the medial region of the body. It has three segments: the prothorax, mesothorax, and metathorax. Each of these segments articulates with a pair of legs. Finally, the abdomen is composed of many segments that might reach up to 7 or 11.True or False. Mature proglottids contain both male and female reproductive organs.
