Reactants used in light- dependent reactions : Carbon dioxide, sunlight and water.
Through tiny holes in their leaves known as stomata, plants absorb carbon dioxide from the atmosphere. Most monocot plants have stomata on both surfaces of their leaves, while dicot plants and a few monocots only have stomata on the bottom epidermis of their leaves.Plants obtain water from the soil around their roots, and water travels via the xylem, a component of the plant's vascular system, to reach the leaves. The vascular bundle in leaves houses the xylem and phloem.The carbon dioxide and water molecules enter the leaf and then migrate into the cells of the mesophyll, the ground tissue layer that lies between the top and lower epidermis. These cells perform photosynthesis using water and carbon dioxide in organelles known as chloroplasts.Reactants used in light- independent reactions : ATP, carbon dioxide, NADPH.
The assembly of a glucose molecule is the final step in the light-independent processes, also known as the Calvin cycle. This stage of photosynthesis necessitates the CO2 that the plant absorbs from the atmosphere.In essence, the plant requires the carbon in the CO2 to make the components of glucose. RubP (ribulose biphosphate), a molecule with five carbons, and a molecule of carbon dioxide are combined by an enzyme called ruBisCo in the stroma. As a result, a six-carbon molecule is produced, which is then split into two three-carbon molecules (3-phosphoglycerate). The term "carbon fixation" refers to this phase of the light-independent processes.Then the light-dependent processes' energy carriers start to contribute. By adding a hydrogen atom to each 3-phosphoglycerate, ATP and NADPH produce two molecules of the simple sugar G3P. (glyceraldehyde-3-phosphate). In the end, one molecule of glucose is created from these two G3P molecules. Due to the addition of electrons, this phase of the light-independent processes is commonly referred to as reduction (or decreasing the sugar).What is the difference between cellular respiration and getting energy from a log by burning it?
The stored chemical energy is eventually released during cellular respiration through a sequence of enzyme-aided processes. When a log burns, chemical energy that has been stored is swiftly released as heat and light.
Living cells need respiration, a biological process, to release energy. A chemical reaction called combustion takes place outside of living organisms or cells. A controlled biological process, respiration. It is impossible to control combustion. When there is oxygen present, substances undergo a chemical reaction known as burning, which produces significant amounts of heat and light. Similarities between burning and respiration For the creation of energy, both processes need oxygen. As a byproduct, they emit carbon dioxide. The metabolic process known as respiration is when an organism obtains energy from the breakdown of glucose molecules in the form of ATP molecules.
When compounds are exposed to oxygen, a chemical reaction known as burning takes place.

What is the first and the most important step in the resuscitation of this newborn?
The single most crucial and efficient phase in cardiopulmonary resuscitation of a critically ill newborn is lung ventilation. The newborn should be placed under a radiant heat source to offer warmth. The baby should then be dried off, their airway should be cleared with a bulb syringe or suction catheter if necessary, and their breathing should be stimulated.
Rescuers should make sure that aided ventilation is being administered as optimally as possible before beginning chest compressions because ventilation is the most effective intervention in neonatal resuscitation and because chest compressions are likely to compete with good ventilation. Thus successful resuscitation depends on efficient ventilation. One cannot always foresee or forecast the necessity for neonatal resuscitation at birth.

Create offspring with a few different levels of Food supply. How does food supply affect the body type of offspring?
Food supply affects body type of offspring by providing resources for growth, lack of it can cause malnourishment and smaller size.
Food supply can have a significant impact on the body type of offspring. When food is abundant, offspring may have the resources to grow larger and develop more muscle mass. Conversely, when food is scarce, offspring may be smaller and have less muscle mass as they do not have access to as many resources for growth. Additionally, if the food supply is inadequate, the offspring may be malnourished and have health problems. It is also worth noting that genetic factors also play a role in determining body type, so food supply may not be the only factor influencing the body type of offspring.

The pancreatic fluid accumulates in sac like pouches called pancreatic acini and eventually flow out the ___________________ duct which carries these secretions to the ___________________
The pancreatic fluid is stored in small, sac-like structures known as pancreatic acini. These secretions then travel along the duodenum duct to the pancreatic duct, where they are released.
The pancreatic duct and duodenum are two essential components of the digestive system. The pancreatic duct carries secretions from the pancreas to the duodenum, which is the first part of the small intestine. The secretions of the pancreas, including digestive enzymes and bicarbonate, are produced in the pancreatic acini and then travel through the ducts to the duodenum.
The duodenum acts as a buffer, allowing the secretions to mix and interact with the other digestive enzymes and bile from the liver, before entering the small intestine. The pancreatic duct and duodenum work together to ensure that the body can properly process and absorb nutrients from the foods we consume.
The pancreatic fluid is essential for proper digestion and absorption of nutrients, as it helps to break down complex molecules in the food we eat. Without the pancreatic duct and duodenum, the body would not be able to process and absorb the necessary nutrients.

What causes increase in rate of cell growth and size?
Cells can grow by increasing the overall rate of cellular biogenesis such that biomolecule production exceeds the overall rate of cellular degradation of biomolecules by proteasomes, lysosomes, or autophagy.
In a typical mammalian dividing cell, proliferation occurs in her G1 phase of the cell cycle and is closely coupled with the S phase (DNA synthesis) and M phase (mitosis). The combined effects of growth factors, hormones, and nutrient availability provide external signals for cell growth.
Cell growth, proliferation and differentiation are primarily controlled by selective transcriptional regulation of gene expression in response to extracellular stimuli. Much of this transcriptional regulation is regulated by the action of sequence-specific transcription factors.

What happens if a cell gets too large for the amount of DNA it has?
The cell is the fundamental unit of life and its structure is highly dependent on the amount of DNA it contains. As such, if a cell gets too large for the amount of DNA it has, it can lead to a range of problems for the cell. This is because the amount of DNA a cell contains determines its size, shape, and the number of processes it can carry out.
One consequence of having too little DNA for a large cell is that it will not be able to divide properly during cellular reproduction. This is because the DNA is responsible for providing instructions to the cell about how to divide and replicate itself, and if there is not enough DNA present, the cell will not be able to divide correctly. As a result, the cell may become deformed or contain abnormal structures or functions.
In addition, when the cell is too large for the amount of DNA it has, it often results in a decrease in the amount of proteins it produces. This is because the DNA is responsible for providing instructions to the cell on how to produce proteins, which are essential for cell growth and development. Without enough DNA to provide these instructions, the cell cannot produce the necessary proteins and is not able to function properly.

c. Repeat inoculations such that the smear is as thick and undiluted as possible.
d. Apply methane to clean the slide prior to smearing inoculum.
Allow the loop to cool after it has been flamed is an important step in the preparation of a proper bacterial smear
A bacterial smear is a small layer of bacteria that is deposited on a slide or a tray for staining. The bacteria are fixed on the slide, and this stops the bacterial sample from being washed away during staining. A crucial step in creating a healthy bacterial smear is allowing the loop to cool after burning.
This is due to the fact that blazing the loop sterilises it by eliminating any bacteria that may be present on the loop, but if the loop is still hot when a sample is taken, the bacteria may be "fried" rather than collected. For effective identification and analysis, it is crucial that the bacteria are gathered in their natural state, which is ensured by allowing the loop to cool.
