Ozone levels in 1920 were primarily monitored using chemical methods, such as the use of chemical indicators and colorimetric analysis.

Potassium iodide-starch paper was used to detect ozone. When exposed to ozone, these indicators changed colour, letting researchers visually monitor ozone concentration.

Colorimetric analysis was also used. Chemical reagents reacting with ozone changed colour. Ozone concentration connected with colour change intensity. Chemical approaches measured ozone qualitatively or semi-quantitatively. They were easy to use but less precise than modern monitoring approaches.

In the following decades, spectrophotometry and ozone analyzers improved the systematic monitoring and quantitative measurement of ozone levels. These improvements made atmospheric ozone monitoring more precise.

Answer:

mitosis animal y vegetal son dos tipos de divisiones nucleares reproductivas en animales y plantas, respectivamente. Durante la mitosis, la cantidad de material genético permanece igual. Por lo tanto, aumenta el número de células en el cuerpo durante el crecimiento, la reparación y la regeneración. La mitosis ocurre en cuatro pasos principales; Profase, metafase, anafase y telofase. los diferencia principal Entre la mitosis animal y la mitosis vegetal es que el huso mitótico en la mitosis animal se forma con la ayuda de dos centriolos, mientras que el huso mitótico en la mitosis vegetal se forma sin ningún centríolo. La mitosis es seguida por citocinesis

Answer:

G2/Growth 2 phase

Answer:

When a cell's DNA is damaged, a sensor protein activates p53, which halts the cell cycle at the G 1start subscript, 1, end subscript checkpoint by triggering production of a cell-cycle inhibitor. This pause buys time for DNA repair, which also depends on p53, whose second job is to activate DNA repair enzymes.

Answer:

1) Diffusion : Is the movement of molecules / ions from a region of higher to lower concentration. It may or may not occur across a semi permeable membrane.

In diffusion there is no challenge involved as it is along the concentration gradient, but in active transport movement of molecules occur against concentration gradient ie; from lower to higher concentration.

2) For active transport, energy is vital for movement, in this case protein molecules function as molecular pumps to enable the cell accumulate glucose/ions, against concentration gradient. Here metabolic energy ATP is required.

3)Facilitated diffusion is a type of passive transport in which ions/molecules cross the semi permeable membrane because permeases present in the membrane facilitate the transport.

Like simple diffusion facilitated diffusion doesn't require metabolic energy and simply occurs across the concentration gradient.

4) Osmosis : is movement of water from hypotonic solution (lower concentration) to hypertonic solution (higher concentration) through a semi permeable membrane.

The cell membrane being permeable to water allows to and fro movement of water molecules along the concentration gradient.

recombinant DNA molecules

Explanation:

Pls give brainliest!

copies of DNA segments from one part of a genome that have been inserted somewhere else are called as recombinant DNA

Recombinant DNA are the molecule which has been modified to include genes from different origin by the process of either genetic recombination or through laboratory techniques.

In the lab condition,  bacteria can be transformed with recombinant DNA and Genetic recombination occurs via crossing over.

scientists use this recombinant DNA technology created  to add to the genome of another organism which means that scientists can easily add genes from one species into bacteria for the production of the product.

For example, insulin is produced by recombinant DNA technology within bacteria where human insulin gene is inserted into a plasmid, then introduced to a bacterial cell, followed by the production of insulin by bacteria cell.

Answer:

The First one, second and forth are false

and the 3 one is true

Explanation:

The DNA is doble stranded in a double helix structure. There are 5 nucleobases (adenine (A), cytosine (C), guanine (G), thymine (T), and uracil(U)), only the first 4 are present in the DNA whilist the U substitutes the T in RNA.

The DNA has deoxyribose sugar while RNA has ribose sugar, that's what gives the doble stranded and single stranded form respectively.

The products of one process are the reactants of the other. Notice that the equation for cellular respiration is the direct opposite of photosynthesis: Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O. Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O.

Answer:

You would die

Explanation:

if you lost your mitochondria you would die

The loss of functional mitochondria would result in a severe energy crisis within the cell, affecting ATP production and impairing Fatty acid metabolism and calcium homeostasis.

Mitochondria are known as the "powerhouses" of the cell because they are responsible for producing most of the cell's adenosine triphosphate (ATP).

The following processes would be affected:

1. ATP production:  Without functional mitochondria, ATP production would be significantly reduced, leading to a severe energy deficit within the cell.

2. Oxidative phosphorylation: Mitochondria are crucial for oxidative phosphorylation, a process that occurs in the inner mitochondrial membrane and generates a large amount of ATP. Without intact mitochondria, oxidative phosphorylation would be disrupted, impairing ATP synthesis.

3. Metabolism of fatty acids: Mitochondria are involved in the breakdown of fatty acids through a process called beta-oxidation. If mitochondria were destroyed, the ability to efficiently metabolize fatty acids would be compromised.

4. Reactive oxygen species (ROS) regulation: If mitochondria were destroyed, the regulation of ROS levels would be impaired, potentially leading to oxidative damage and disruption of cellular processes.

5. Calcium homeostasis: Mitochondria are involved in maintaining calcium homeostasis within cells. Loss of functional mitochondria would disrupt calcium regulation, which could affect various cellular functions, including muscle contraction, enzyme activity, and cell signaling.

Therefore, the loss of functional mitochondria would result in a severe energy crisis within the cell, affecting ATP production and impairing various metabolic processes.

Explanation:

Fair Chase strikes a balance between the hunter's ability and tools and the animal's capacity for escape. Fair Chase is mainly determined by people and their level of hunting prowess.

Fair chase is defined as a term used by hunters to refer to a moral method of taking down large game animals. A fair chase is the ethical, sportsmanlike, and legal chase and taking of any free-ranging wild game animal in a way that does not offer the hunter an improper or unfair advantage over the game animals, according to the Boone and Crockett Club.

A wildlife management organization establishes hunting laws in the majority of states. Regular meetings of these organizations will allow members of the public to express their opinions and offer suggestions. When the entire hunting experience is their major focus, seasoned hunters reach the sportsman stage. Although they may still have a target animal or a number of kills in mind, hunters at this stage don't plan their hunts around these objectives.

Thus, fair chase strikes a balance between the hunter's ability and tools and the animal's capacity for escape. Fair Chase is mainly determined by people and their level of hunting prowess.
