How does sulfa antibiotics affect and destroy bacteria?.

Aerobic respiration takes place in the mitochondria, and fermentation takes place in the cytoplasm.

The processes by which cells break down organic molecules to produce ATP are called cellular respiration.

Cellular respiration is an exergonic process, where part of the energy contained in food molecules is used and another part is lost as heat.

Cellular respiration occurs in different cell compartments:

Mitochondria are organelles present in eukaryotic cells where aerobic respiration takes place from the degradation of organic compounds.

Mitochondria are made up of two membranes, an outer one that is smooth and an inner one that folds inward to form ridges.

The selective permeability of the inner membrane is of fundamental importance since it enables the mitochondria to allocate the energy of respiration for the production of ATP.

Fermentation is the degradation of organic compounds in the absence of oxygen; produces less energy than aerobic processes, both alcoholic and lactic fermentation, occurs in the cytoplasm.

Therefore, we can conclude that aerobic respiration takes place in the mitochondria, and fermentation takes place in the cytoplasm.

Answer:

They are in different states and have different temperatures.

Explanation:

Plate tectonics is defined as the breaking of the Earth's strong outer layer into a mosaic of plates that move into a mechanically weaker layer.

The two types of layers responsible for Plate tectonics or tectonic activity are crust and mantle. These two are most responsible for tectonic activity because they are in different states and have different temperatures. Due to this, pressure in the crust (below the mantle) forces mantle magmas that erupt out of volcanoes, cool, and solidify through cracks to Earth's surface.

Lignin occurs in vascular land plants but not charophytes because lignin is a complex polymer found in the cell walls of vascular land plants, providing structural support and rigidity.

The correct answer is option B)

Lignin is a complex polymer found in the cell walls of vascular land plants, providing structural support and rigidity. It is responsible for the ability of vascular plants to grow tall and develop sturdy tissues, such as xylem and phloem, which are essential for water and nutrient transport throughout the plant.

Charophytes, or stoneworts, are a group of green algae that are considered the closest living relatives of land plants. While they share many features with land plants, they lack true vascular tissues and do not possess lignin in their cell walls. Without lignin, charophytes do not have the same level of structural support as vascular land plants, and they typically have a more limited growth form.

The other options listed (A) sporopollenin, (C) chlorophyll a, (D) cellulose, and (E) chlorophyll b are found in both vascular land plants and charophytes. Sporopollenin is a durable polymer that forms the outer layer of spores and pollen grains, which is present in both groups. Chlorophyll a and chlorophyll b are photosynthetic pigments found in the chloroplasts of both charophytes and vascular land plants. Cellulose, a polysaccharide, is a major component of the cell walls in both groups as well.

In summary, the presence of lignin is a characteristic that distinguishes vascular land plants from charophytes. Vascular land plants possess lignin, which provides structural support and allows for the development of specialized tissues, while charophytes lack this feature.

Answer:

Through photosynthesis, plants produce the most abundant form of carbohydrate, which is  _starch_.

Plants uptake carbon dioxide and water to produce starch and oxygen as a by-product in the process of photosynthesis

But when the organic food is transported through phloem, the form of organic food should be sucrose instead of starch

Glucose, on the other hand, is the carbohydrate that is created by photosynthesis in the greatest amounts.

A simple sugar called glucose serves as the fundamental component of more complex carbohydrates. It is created when sunlight is utilised to break water molecules into oxygen and hydrogen ions as part of the photosynthesis process. The plant can consume the glucose right away or store it for later use once the hydrogen ions and carbon dioxide mix.

Numerous processes in plants need glucose. While some of it is instantly used as a source of energy to drive cellular functions, other portions are transformed into other types of carbohydrates including starch and cellulose. While cellulose is utilised to create the plant's cell walls, starch is used to store glucose for later use.

Glucose is the most significant byproduct of photosynthesis and is essential for the development and survival of plants. With the help of this remarkable process, plants are able to absorb carbon dioxide from the environment, utilise solar energy to power their metabolism, and produce the carbohydrates they need to thrive.

The classification of hormones based on their chemical structure helps in understanding their biosynthesis, mode of action, and regulation.

Hormones are chemical messengers produced by specialized cells in the endocrine glands that are released into the bloodstream to regulate the functions of target cells and organs. These molecules are classified based on their chemical structure into three main categories: peptides/proteins, steroids, and amino acid derivatives.

Peptide/protein hormones are composed of chains of amino acids. Examples include insulin, growth hormone, and follicle-stimulating hormone. These hormones are usually stored in secretory vesicles before they are released into the bloodstream in response to a specific stimulus.

Steroid hormones are derived from cholesterol and are lipophilic. They include hormones such as testosterone, estrogen, and cortisol. Steroid hormones are synthesized in the smooth endoplasmic reticulum of steroidogenic cells and are released into the bloodstream after they are synthesized.

Amino acid derivatives hormones are derived from the amino acids tryptophan and tyrosine. Examples of these hormones include melatonin, thyroid hormones, and adrenaline. These hormones are synthesized in specialized cells and are released into the bloodstream in response to a specific stimulus.

In this condition, known as hyponatremia or water intoxication, where the concentration of sodium in the blood is lower than normal due to excessive water intake during exercise.

The immediate response of the blood cells would be to attempt to restore the balance of sodium concentration. When sodium levels decrease, water enters the cells through a process called osmosis, causing the cells to swell. To counteract this, the blood cells activate regulatory mechanisms to prevent further swelling and maintain cell integrity.

The blood cells would activate ion channels and transporters on their cell membranes to pump out excess water and maintain the proper concentration of sodium. This process is crucial to prevent cell rupture or damage that could occur due to excessive swelling. The cells work to restore the normal osmotic balance, allowing sodium levels to increase and water levels to decrease within the cells.

It is important to note that hyponatremia can have severe consequences if left untreated. It can lead to symptoms such as confusion, seizures, and, in extreme cases, even coma or death. Seeking medical attention is crucial if hyponatremia is suspected, as prompt intervention can help restore the electrolyte balance and prevent further complications.

" Nitrogen is transformed into nitrates by soil bacteria" is correct on how atmospheric nitrogen is made available to plants and animals.

Direct use of atmospheric nitrogen by both plants and animals isn't possible owing to its gaseous state; the utilization of certain kinds of soil bacteria such as Rhizobium and Azotobacter occurs for converting it into an appropriate form through the process called nitrogen fixation.

These bacteria produce ammonia that undergoes further transformation into nitrates facilitated by additional bacterial types like Nitrosomonas and Nitrobacter. Thereafter, nitrates are absorbed from the earth via plant roots to assist in building protein molecules along with several other crucial components.
