Animalia are heterotrophs while plantae are autotrophs

A. The increased biomass in the sunlit dish came from the carbon and oxygen atoms present in the carbon dioxide it took up during photosynthesis that it used to synthesize organic molecules.
Plants use photosynthesis in order to convert light energy (from the sun) into chemical energy, stored in carbohydrate molecules (such as sugars). This chemical energy can be further transformed to fuel some of the organism's activities. This chemical reaction (photosynthesis) is light-dependent and includes the use of carbon dioxide and water to produce sugars and oxygen. The seeds that were put on a sunny windowsill had plenty of light energy needed for their photosynthetic activity. This resulted in the accumulation of sugar molecules in the plant tissues and an increase in the biomass. These sugar molecules were synthesized by the carbon and oxygen atoms comprising the carbon dioxide molecules absorbed during photosynthesis.
B. The most likely explanation for the why the dark-grown seedling lost biomass is that cellular respiration in the cells of the seedlings consumed the starch and oils present in the seed as sources of energy.
Plants use cellular respiration in order to constantly supply energy to their cells. This chemical reaction uses the sugar molecules produced by the photosynthesis and stored in the plant tissues to get energy. Seeds put in a dark cupboard did not have access to any light energy, therefore, they could not perform photosynthesis. As a result, they had to perform respiration and consume starch and oils which were present in the seed to get the necessary energy. This resulted in a reduction in their biomass.
Activated partial thromboplastin
time (aPTT) is the blood test to monitor anticoagulation therapy for patients
taking heparin. The purpose of carrying out the Activated partial
thromboplastin time (aPTT) test is to find out if the right dose of heparin is
being used.
<span>Two checkpoints during the cell cycle that regulate cell division are right before S phase and M phase.
</span>Cell cycle checkpoints are control mechanisms <span>necessary for proper cell division. </span><span>In the cell cycle, there are two checkpoints: </span><span>the G1 checkpoint and the G2 checkpoint. <u>The G1 checkpoint is right before the S phase, and G2 checkpoint is right before the M phase.</u>
If something is wrong at the G1 checkpoint, the cell will not enter the cell cycle. It is important to be delayed before cell enters S phase where DNA replication commences.
The G2 checkpoint is a DNA damage checkpoint and if DNA is damaged, entering the cell cycle is delayed before mitosis (M phase).</span>
