The plant absorbed more oxygen.
The plant absorbed less oxygen.
The plant was exposed to more intense light
The plant absorbed more carbon dioxide.
The production of glucose increase in plant cells when the intensity of light is increased and the amount of carbon dioxide absorbed is increased. These affect the rate of reaction.
What is Photosynthesis?Photosynthesis is the process of formation of glucose (sugar) in the green cells of plant. Photosynthesis takes place during the daytime as it requires sunlight to proceed the reaction. The reaction takes place in the chloroplast of plant cells.
Factors which affect the rate of photosynthesis are light intensity and carbon dioxide concentration. Light intensity is directly proportional to the rate of photosynthesis, as the intensity of light increases the rate of photosynthesis also increases.
Similarly, carbon dioxide is also proportional to the rate of photosynthesis as carbon dioxide is a reactant in this process. With the increase in the amount of reactants, the rate of a chemical reaction increases and hence more product is formed.

2. The lime water turns milky in colour
3. To act as filters
4. To enable easy penetration of the root of planted crops.
See detailed explanation below
Explanation:
2. Our exhaled air principally contains carbon dioxide gas (CO2), which reacts with like water to produce a milky solution. The lime water is a solution of Calcium hydroxide (CaOH2), which chemically reacts with the C02 content of our exhaled air to form a compound called Calcium carbonate (CaCO3). Calcium carbonate is a whitish compound that appears chalky/milky.
3. Our nostrils contain a cavity called nasal cavity, which is lined with mucus (a viscous substance). The mucus helps to keep the nasal cavity wet. The hair in the nostrils also help prevent large particles in inhaled air from entering into the nasal cavity. The hair and mucus works together to filter out shirts and germs like bacteria etc from entering into the lungs.
4. Farmers loosen the soil which they plant their crops by mixing the layers of the soil. Loosening the soil encourages or promotes a deep and easier penetration of the plant roots. It also helps the soil to be properly drained and aerated i.e. penetration of water and air into the soil respectively.

Answer:
Biotic factors and abiotic factors, plant and light energy, herbivores, heterotrophs, omnivores, carnivores, primary consumer, decomposers and tertiary consumers.
Explanation:
Both biotic and abiotic factors are interacting with each other in an ecosystem. Plants use light energy from the sun to produce their own food. Herbivores are the organisms that feed on producers (plants). Heterotrophs are those organisms which are unable to make their own food. Omnivores are the organisms that eat both plants and animals. Carnivores feed on animals only. Primary consumers are the consumer which feed on plants. Decomposers helps in the breakdown of dead bodies of plants and animals. Tertiary consumers feed on secondary consumer.

In order for translation to occur: Please choose the correct answer from the following choices, and then select the submit answer button. transcription must be occurring simultaneously. there must be large numbers of free amino acids present in the cytoplasm. the DNA must produce large numbers of free amino acids. replication must be occurring simultaneously. the nuclear membrane must first dissolve
Answer:
there must be large numbers of free amino acids present in the cytoplasm
Explanation:
In order for translation to occur, there must be a large number of free amino acids in the cytoplasm.
These free amino acids are usually carried by the transfer RNA which also carries the corresponding mRNA codon.
During translation, as the codons in the mRNA match their complements in the tRNA, the amino acid being carried by the tRNA is released and a peptide bond is formed between subsequent amino acids until the required polypeptide bond is formed.
Translation and transcription only occur simultaneously in prokaryotic cells where there is no barrier between the cell's genetic materials and the cytoplasm, unlike in eukaryotic cells where the genetic materials are housed in the membrane-bound nucleus.

Thylakoids contain clusters of chlorophyll and proteins known as . They absorb sunlight and generate high-energy that pass along the .
Answer:
1) Photosystems
2) Thylakoid membrane
Explanation:
Photosynthesis is an important phenomenon for the cells of autotrophic organisms like green plants. It is the process through which they obtain their energy source. Photosynthesis, which consists of two stages, occurs in the Chloroplast of the cell.
The light dependent stage occurs in the thylakoid lumen of the CHLOROPLAST while the light independent stage occurs in the stroma. The thylakoid is a membrane-bound sac usually organized in stacks called GRANA.
The Chlorophyll pigment, which captures the photon of light needed for the photosynthetic process, is contained in the thylakoid. Also, embedded in the thylakoid space are protein complexes called PHOTOSYSTEMS, which are involved in the capturing photons of light and transferring of electrons. The Photosystems 1&2 are the functional units of photosynthesis.
The high energy generated by the Photosystems are transferred from one electron carrier to another along the thylakoid membrane in order to generate ATP and NADPH. This process is called Electron transport chain.
Thylakoids are the membrane-bound structures present within chloroplasts of the plant cell. Thylakoids consist of photosystems and are surrounded by the thylakoid membrane.
The correct blanks for the given statement are:
Thylakoids contain clusters of chlorophyll and proteins known as photosystems. They absorb sunlight and generate high energy that passes along the thylakoid membrane.
Photosystems in the thylakoids are the structural and functional protein complexes, which play a crucial role in performing photosynthesis. These systems are present along the thylakoid membranes, and carry out the primary photochemistry of photosynthesis.
The thylakoid membrane is involved in the light-dependent reactions of photosynthesis. The membrane absorbs light energy and is then converted into chemical energy. The high-energy generated is passed along the thylakoid membrane.
Therefore, the correct answers are photosystems and thylakoid membrane.

Place the steps of biofilm formation in the correct order: 1. Quorum sensing and the establishment of the extracellular matrix commences as microbes attach more stably. 2. Surface (substratum) is preconditioned by environmental molecules. 3. Biofilm matures and some microorganisms escape to the planktonic state. 4. Microbes attach and detach from the preconditioned surface.
Answer:Step order:
2. The surface (substrate) is preconditioned by environmental molecules.
4.Microbes bind and detach from the preconditioned surface.
1.Quorum detection and extracellular matrix establishment begins as microbes bind more stably.
3. The mature biofilm and some microorganisms escape the planktonic state.
Explanation:
The biofilm is a highly complex structure where many microorganisms coexist, compete, reproduce, feed, within a micro-system with many ideal conditions for each microorganism that is housed in it.
The biofilm is resistant to non-selective antimicrobials, that is, to disinfectants such as sodium hypochlorite, chlorhexidine, among others.
Evidence was also presented that they are resistant to selective antimicrobials such as antibiotics, that is why they have great virulence factors or potential to trigger pathology.
The solution to destroy a biofilm is mechanical sweeping, with brushing as it happens on our teeth or even with the catheter cleaning brushes that are used (in addition to the sterilization methods).
This biofilm presents separate colonies in its interim with a fluid that it travels transmitting signals, food, toxins, resistant factors between these different types of microorganisms. This fluid and this communication between them is called quorum sensing and not all microorganisms tolerate it.
Many microorganisms compete with each other for the medium, an example is streptococcus mutating in the dental biofilm, which generates an acidic medium by metabolizing carbohydrates within the biofilm, thus generating that those bacteria that live in neutral or alkaline ph cannot reproduce and die.
The biofilm can be contained by bacteria, viruses, fungi and even parasites, but what they all have in common is that they have the ability to reproduce on an inert surface such as catheters, dental surfaces, silicone hoses.

What are digestive enzymes? Give three examples of digestive enzymes and briefly describe their specific functions.
Answer:
Digestive enzymes are the natural substances our body needs to help break down and digest food
We have three main digestive enzymes :
Proteases: These enzymes break down protein into small peptides and amino acids.
Lipases: break down fat into three fatty acids plus a glycerol molecule.
Amylases: Are responsible for breaking down carbs like starch into simple sugars.
Explanation:
Digestive enzymes are proteins that catalyze mainly hydrolysis reactions that make nutrients absorbable in the digestive tract. Pepsin is a gastric enzyme that turns proteins into albumoses and peptones which are shorter peptide chains that are then hydrolyzed to even shorter chains until amino acids by intestinal enzymes. Pancreatic amylase is an enzyme that turns starch(a polysaccharide) into maltose(a disaccharide). Lipase is present in the gastric juice, the pancreatic juice, and the intestinal juice. This enzyme catalyzes the hydrolysis of lipids(mainly triglycerides) into fatty acids and glycerol. When incomplete hydrolysis occurs triglycerides can become monoglycerides.
