Carbon dioxide is drawn from the atmosphere by photosynthesis while it is released into the environment via cellular respiration.

Around the world, cellular respiration and photosynthesis exchange carbon dioxide and oxygen, assisting in maintaining constant amounts of both gases in the atmosphere. It will be clear that photosynthesis and cellular respiration have the opposite effects if you look at the equations for both processes.

One process's reactants become the other's products. Around the biosphere, matter and energy are moved via biochemical processes like photosynthesis and cellular respiration. These two processes result in the exchange of carbon dioxide and oxygen between living things and their environment. A plant's ability to grow, develop, and survive depends on both photosynthesis and respiration.

A non-steroidal anti-inflammatory medicine (NSAID) called ibuprofen is used to treat inflammation, fever, and discomfort. Ibuprofen can be successfully absorbed by the intestines and transferred across the intestinal epithelial tissues into the circulation despite its poor solubility in water.

Passive diffusion is one method through which ibuprofen can diffuse through the intestinal epithelial membrane. Molecules travel by a process called passive diffusion from a region with a higher concentration to one of a lower concentration. Ibuprofen is in the ionised state at the pH of the digestive system (hcl 7), which makes it much more hydrophobic and thus more able to pass the liposome cell membrane. Motrin has a pKa of roughly 5.  Facilitated diffusion is another method by which ibuprofen can pass through the intestinal epithelial cell membrane. By means of certain transporters, chemicals can penetrate a cell membrane through a process called "facilitated diffusion." Ibuprofen does not have a unique transporter in human cells, but it is hypothesised that it can penetrate the cell membrane by attaching to the same transporters that allow other medications and chemicals, including amino acids and glucose, to enter the body. It's also important to remember that ibuprofen can be taken with meals because doing so might boost the drug's solubility and therefore its bioavailability.  It's crucial to note that this explanation has been simplified, and the precise method through which ibuprofen works.

The correct option is  A; An increase in the number of receptors on the post-synaptic cell

Researchers discovered that rapidly and repeatedly activating synapses in the rabbit hippocampus made them stronger; the volume control was turned up and stayed that way. This long-term increase in synaptic strength was dubbed long-term potentiation, or LTP.

An excitatory synapse occurs when an action potential in a presynaptic neuron raises the likelihood of an activity potential in a postsynaptic neuron.

Excitatory (or EPSPs) PSPs increase the possibility of a postsynaptic action potential happening, while inhibitory (or IPSPs) PSPs lower this likelihood.

Fertilization is the process in which haploid gametes fuse to form a diploid cell called a zygote.

A zygote is the cell that results from the union of the sperm and the egg. The zygote has all the genetic material required to develop into a new organism because it has all the chromosomes from both parents.

Egg and sperm cells come into contact during fertilization, and the sperm cell then penetrates the egg cell. Following this, the nuclei of the egg and sperm cells combine to create a single diploid cell that has twice as many chromosomes as the haploid gametes. Following a sequence of divisions known as cleavage, the zygote develops into a multicellular organism.

1 - Plants are essentially autotrophic, chlorophyll-containing, non-motile organisms. They are multicellular eukaryotic organisms.

2 - Stomata are minute pores of eliptical shape, consists of two specialized epidermal cell called guard cells .This is an adaptation to check excessive transpiration in these plants .The numbers of stomata differs in tropical plants and desert plant because tropical plants have plenty of water in their environment while on the other hand, desert plants have lower number of stomata in order to conserve more water and increase its survival.

3 - Vascular tissues of plant are xylem and phloem. If xylem will be damaged then plant will not be able to transport water from soil through roots to leaves. If phloem will be damaged then nutrients produced during photosynthesis will not be able to reach each and every part of the plant body.

Phloem is responsible for transporting food produced from photosynthesis from leaves to non-photosynthesizing parts of a plant such as roots and stems. The phloem carries important sugars, organic compounds, and minerals around a plant.

Xylem is a type of tissue in vascular plants that transports water and some nutrients from the roots to the leaves. Phloem is the other type of transport tissue; it transports sucrose and other nutrients throughout the plant. Xylem and phloem give vascular plants their classification; they are the vascular tissues that transport substances throughout the plant.

4 - The dermal tissue system—the epidermis—is the outer protective layer of the primary plant body (the roots, stems, leaves, flowers, fruits, and seeds). The epidermis is usually one cell layer thick, and its cells lack chloroplasts.

Also similar to animal skin, the dermal layer of plants may also contain little hairs called trichomes. Trichomes are unicellular or multicellular extensions from the epidermis and are made up of a stalk and a glandular head. They vary in size, density, and function from plant to plant. Some plants, such as stinging nettle, contain trichomes with needles that inject formic acid and other toxins in order to deter consumption by herbivores. Plants such as winterfat, a flowering desert plant native, have evolved trichomes which reflect the sunlight, shade the plant, and keep it cool in its desert environments. In addition to protecting plants from heat and herbivores, trichomes also may protect the plant by retaining moisture, insulating the plant from frost, and reducing evaporation due to wind.

5 - The length of time a plant can survive with damaged roots depends on the extent of the damage and root loss. If more than 50% of a plant?s root is damaged, the plant will survive up to 5 days if not further care is taken to help revive the plant. Plants need roots to absorb nutrients and water from the soil.

We can confirm that with damaged ground tissue, a plant will most likely not be able to survive. What we know about ground tissues in plants. The ground tissue forms an abundant part of all plant tissues. This tissue includes all plant tissue that is neither vascular nor dermal.

In addition to regulating enzymes with activators and inhibitors, cells also regulate enzyme activity by limiting the availability of substrates.

When a certain amount of enzyme is present, the rate of an enzymatic reaction grows as the concentration of the substrate increases until a limiting rate is achieved, at which point an increase in the concentration of the substrate has no effect on the reaction rate. By this time, there is so much substrate available that it is essentially bonded to every enzyme active site. In other words, the substrate has completely saturated the enzyme molecules. Before the surplus substrate molecules may react and be released, the substrate that is already bound to the enzymes must first react (or been released without reacting).

An enzyme-catalyzed reaction initially progresses at a faster pace as substrate concentration rises. This rise in reaction rate levels off as the substrate saturates the enzyme molecules. An enzyme's concentration increases along with the speed of an enzyme-catalyzed process.
