Due to the absence of proteolytic enzymes.

Explanation:

The study diagnosis that small intestine digested protein slowly due to the absence or decrease quantity of proteolytic enzymes in the small intestine. Proteolytic enzymes are responsible to speed up the digestion process and after digestion amino acid is produced which is directly injected into the blood that is used by the body for the formation of muscles.

Photosynthesis in chloroplasts involves major steps such as light absorption, electron transport, ATP synthesis, and carbon fixation. It begins with light-dependent reactions in photosystems I and II, followed by electron transport and ATP synthesis.

Step 1: Photosynthesis is a complex process that occurs in the chloroplasts of plants, involving several major steps such as light absorption, electron transport, ATP synthesis, and carbon fixation.

Step 2:Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose. It occurs in the chloroplasts, specifically in three main stages: light-dependent reactions, electron transport chain, and the Calvin cycle.

During the light-dependent reactions, light energy is absorbed by chlorophyll molecules in photosystem II (PSII) and photosystem I (PSI). In PSII, water molecules are split, releasing electrons, protons (H+ ions), and oxygen. The electrons move through an electron transport chain, creating a proton gradient across the thylakoid membrane. This gradient is essential for ATP synthesis by ATP synthase, using the energy from the electron flow.

In PSI, electrons are re-energized by absorbing more light energy and are ultimately used to produce NADPH, another energy carrier. The ATP and NADPH generated in the light-dependent reactions are then used in the Calvin cycle.

The Calvin cycle, also known as the light-independent reactions or carbon fixation, occurs in the stroma of the chloroplast. It uses ATP, NADPH, and carbon dioxide (CO2) to produce glucose (G3P), which serves as a building block for sugars and other organic compounds. The cycle regenerates the starting molecule, ribulose bisphosphate (RuBP), allowing the process to continue.

Explanation:

itsIn ecology, carrying capacity means the maximum population size of a species that can be sustained by an environment given the available resources.

In a graphic that plots time vs population size, the moment the carrying capacity is reached can be identified easily by looking at which point the population stops growing and it just maintains its size.

Among the four species plotted here, species 4 is the one that reaches it's maximum first, around day 20, and after that just keeps the same population size.

If the student later tested the bubbles collected in the test tube, she finds that it was made up of oxygen.

what is photosynthesis?

Photosynthesis is the process by which green plants use the energy from sunshine to transform carbon dioxide and water into food.

Since oxygen is the gas that plants release during photosynthesis, we can infer that the bubbles are oxygen.

In this instance, we can also affirm that the fluorescent light-exposed ant displayed more bubbles than the other plant.

Since the light made it possible for this plant's photosynthetic rate to increase, more oxygen was released into the environment.

Therefore, if the student later tested the bubbles collected in the test tube, she finds that it was made up of oxygen.

Phylogenetic order from the largest most inclusive group to the smallest and most exclusive group: Protostomes > Ecdysozoa > Arthropods > Insects.

Phylogeny is a classification description that shows the kinship relationship of a species with its ancestors and the evolutionary relationship between organisms.

Protostomes are divided into two groups:

Arthropods are triploblastic protostomes. They also have a nervous system with a dorsal "brain", an oropharyngeal nerve, and a pair of ventral nerves. Like annelids, their bodies are segmented both internally and externally. This is taken as evidence that annelids and arthropods are closely related. We now believe that segmentation is a convergent property.

Insects are the most successful group of organisms on the planet. Every third species of organism is an insect. During its development, the insect acquires several features that contribute to its success.

A chemical preservative stops items from decomposing. Some preservatives are used to cure wood or metal, while others are applied to food. Food preservation is "the science that deals with the process of preventing food from decaying or spoiling so that it can be stored in a fit condition for future use." Food quality, edibility, and nutritional content are all guaranteed via preservation.

Drying: The oldest method of food preservation is drying. By using this technique, water activity is reduced, preventing bacterial growth. Drying makes food lighter so it can be transported more readily. Modern drying methods include bed dryers, fluidized bed dryers, freeze drying, shelf dryers, spray drying, commercial food dehydrators, and household ovens, in addition to the traditional methods of using the sun and wind. Examples of dried items using this technique include meat and fruits, apples, apricots, and grapes.

Freezing: Food prepared and frozen is kept in cold storage. Although potatoes can be controlled in dark areas, potato preparations must be frozen.

Smoking: Food is cooked, flavored, and preserved through smoking, which exposes it to wood smoke. Meats and fish are typically smoked because the smoke has antibacterial and antioxidant properties. Assorted smoking techniques are employed, including hot smoking, cold smoking, smoke roasting, and smoke baking. Smoking increases the risk of cancer when used as a preservative.

Vacuum packing creates: By making bottles and bags impermeable, vacuum packing creates a vacuum. Bacteria perish because there is no oxygen in the newly generated vacuum. Typically applied to dry fruit.

Salting and Pickling: Curing, commonly referred to as salting, removes moisture from goods like meat. Pickling is the process of preserving food in a salt solution (brine) or vinegar (acetic acid); in Asia, food is sometimes preserved in oil. At a 20% concentration, salt kills and stops the growth of microorganisms. Pickling can be done in many ways, including chemical pickling and fermentation pickling. To extend the shelf life of commercial pickles, sodium benzoate or EDTA is added.

Sugar: Fruits can be preserved with sugar in syrup form or crystallized form, depending on whether the material to be preserved is boiled in the sugar until it crystallizes, like candied peel and ginger. Another use is for fruit superficially coated in sugar syrup and then glazed. Alcohol and sugar are combined with preserving upscale foods like fruit in brandy.

Lye: Lye, also referred to as sodium hydroxide, makes food alkaline and inhibits the growth of microorganisms.

Canning and bottling: Sealing cooked food in sterile bottles and cans is the definition of canning and bottling. Boiling the container destroys or weakens bacteria. Various amounts of time or space are used for cooking food. The food is more at risk of rotting after the can or bottle has been opened.

Photosynthesis takes place on the folds in prokaryotes and in specialised organelles in eukaryotes. Prokaryotic cells don't have specific organelles or a remote nucleus.

What is photosynthesis?

Plants absorb water (H2O) and carbon dioxide (CO2) from the soil and atmosphere during photosynthesis. Water is oxidised, which means it loses electrons, while carbon dioxide is reduced, which means it receives electrons, inside the plant cell. Water is converted into oxygen and carbon dioxide into glucose as a result. After storing energy within the glucose molecules, the plant releases the oxygen back into the atmosphere.

Chloroplasts, which are tiny organelles found inside plant cells, are there to store solar energy. Chlorophyll, a light-absorbing pigment found in the thylakoid membranes of the chloroplast, is what gives plants their green hue.
