A particular cell has a mutation that causes it to make defective centromeres. What would you expect to occur during mitosis?
BigorU [14]

Answer:

The correct answer is D Sister Chromatids may not attach to each other.

Explanation:

Centromeres are the specific point to which the sister Chromatid binds.That means Centromere function to hold the sister Chromatids.

        Now according to the question if mutation causes formation of defective centromere then the normal functioning of that centromere will be hampered.

         As a result the sister chromatid may not attach to each other.

CAM photosynthesis limits CO2 fixation to nighttime hours in order to (A) allow water to enter leaf spaces during the daylight h
bixtya [17]

Answer:

(B) open stomata only at night, limiting water loss because of heat and low humidity.

Explanation:

CAM plants are found in the regions characterized by very hot and dry environmental conditions. These plants reduce the water loss through transpiration by exhibiting CAM photosynthesis.  

They open the stomata during night time when the air is cooler and rich in moisture. They take in CO2 during night time and fix it into the oxaloacetate which in turn is converted into malate and is stored in the vacuoles.  

During day time, stomata remain closed to prevent water loss and the CO2 trapped during night time (released by decarboxylation of malate) enter the Calvin cycle.

4. Many organisms can withstand periods of oxygen debt (anaerobic conditions). Yeast undergoing oxygen debt converts pyruvic aci
EleoNora [17]

Explanation:

The anaerobic respiration that is respiration which is involved in producing energy molecules like ATP without oxygen evolved earlier than aerobic respiration.

The anaerobic respiration undergoes glycolysis which produces pyruvic acid form lactic acid, ethanol, and very low amount of ATP. This anaerobic respiration is known as fermentation.

The fermentation produces a very low amount of ATP that is only 2 molecules but the amount is sufficient for the simple organisms to survive therefore the fermentation is still performed by the organisms.

Abstract

Nature was and still is a prolific source of inspiration in pharmacy, cosmetics, and agro-food industries for the discovery of bioactive products. Informatics is now present in most human activities. Research in natural products is no exception. In silico tools may help in numerous cases when studying natural substances: in pharmacognosy, to store and structure the large and increasing number of data, and to facilitate or accelerate the analysis of natural products in regards to traditional uses of natural resources; in drug discovery, to rationally design libraries for screening natural compound mimetics and identification of biological activities for natural products. Here we review different aspects of in silico approaches applied to the research and development of bioactive substances and give examples of using nature-inspiring power and ultimately valorize biodiversity.
