20The trout population in a large lake has been threatened by the accidental introduction of parasitic sea lampreys through man-made channels from the ocean. The lampreys attach themselves to the sides of trout, eventually killing many of the trout. Lampreys leave wounds on the skin of the trout. To control the lamprey population, costly chemicals, traps, and barriers have been used to prevent sea lampreys from reproducing. The graph below shows the effect of this lamprey control program in reducing the number of wounds on the native trout population.

Meiosis, also known as "reduced division," involves cutting the number of chromosomes in half to ensure that the baby's chromosomal count will be accurate after the fusing of the sperm and the egg.

Meiosis, a type of cell division in which the number of chromosomes in a parent diploid cell is cut in half, is the process that results in the production of haploid gametes.

Reproductive cloning is the process of creating genetic copies of entire organisms, whereas therapeutic cloning is the process of creating genetic copies of tissues or organs to replace damaged body parts.

Reproductive cloning is the intentional creation of genetically identical individuals. Each newly created person is a clone of the original. Natural clones are monozygotic (identical) twins. Somatic cell nuclear transfer is used in reproductive cloning to create an animal that is genetically identical to a donor animal. The newly created embryo is placed back into the uterine environment where it can implant and develop in reproductive cloning. Dolly the sheep is probably the best-known example.

The transfer of nuclear material isolated from a somatic cell into an enucleated oocyte with the goal of producing embryonic cell lines with the same genome as the nuclear donor is known as therapeutic cloning. The process of creating a cloned embryo solely for the purpose of producing embryonic stem cells with the same DNA as the donor cell is known as therapeutic cloning. These stem cells can be used in experiments to better understand disease and develop new treatments.

Carbon dioxide (CO2) and other greenhouse gases are released by hydrocarbons, which contribute to air pollution and climate change. CO2 is an inevitable byproduct of the combustion of hydrocarbons.

Aside from the repercussions of burned hydrocarbons, unburned hydrocarbons are even more hazardous when they escape. Motor exhaust, as well as evaporating petroleum and gas, include toxic, carcinogenic compounds. Heavy forms can pollute groundwater and soil.

Because methane, the most discussed hydrocarbon in this context, is a more potent heat-trapping greenhouse gas than carbon dioxide, it has a bigger influence on global warming when it escapes into the atmosphere unburned.

The term "biochemical oxygen demand" (BOD) refers to how much oxygen is used by bacteria and other microorganisms during the aerobic decomposition of organic matter at a particular temperature.

One thing you cannot see in a lake's water when you look at it is oxygen. Temperature, pH, the type of microorganisms present, as well as the type of organic and inorganic material in the water, all have an impact on the rate of oxygen consumption. Wastewater from sewage treatment plants often contains organic elements that are degraded by microbes, which use oxygen in the process. If the B.O.D. is high, microbes are utilizing the majority of the oxygen. Larger aquatic species find it difficult to thrive in this environment. On the other hand, when the BOD is low, there is a surplus of oxygen, which results in good water quality.

The easiest way to sum up how predation affects the species engaged in the predator-prey interaction is benefit—harmed.

Predation is a sort of relationship between two organisms in which one creature, known as the prey, suffers harm while another, the predator, benefits. Predators kill their victim and eat it in order to survive. For instance, when a lion hunts its target and kills the deer, the lion benefits because it gets to eat the animal, but the deer suffers since it lost its life. When resources are scarce and species compete to get them, competition occurs in an ecosystem.

Plasmids, genes required for aging and metabolar activity. Cell structure is an important component in modern genetic engineering techniques.

Extrachromosomal DNA that is physically different from chromosomal DNA and has its own replication apparatus is called a plasmid. Small, circular, double-stranded DNA molecules known as plasmids are most usually found in bacteria, while they can also occasionally be detected in archaea and eukaryotic cells. Plasmids usually carry genes that give an organism a survival benefit and a selective advantage in the natural world, such as antibiotic resistance. Contrary to chromosomes, which are enormous and contain all the genetic information necessary for regular cellular function, plasmids are frequently quite small and only contain supplementary genes that may be useful in particular contexts or conditions. Artificial plasmids are often used in molecular cloning as vectors to encourage the replication of recombinant DNA sequences inside hosts. Plasmids are regarded as replicons, or DNA molecules that can replicate on their own in the appropriate host. Similar to viruses, plasmids are not commonly considered to be a component of life. Plasmids are typically transferred from one bacterial species to another by conjugation (even those of a different species).

Because the two DNA strands are made up of simpler monomeric units termed nucleotides, they are referred to as polynucleotides. Each nucleotide is made up of a phosphate group, a deoxyribose sugar, and one of the four nitrogen-containing nucleobases (cytosine [C], guanine [G], adenine [A], or thymine [T]).

The haze thickens as the cataract continues to grow. Cataracts block light from reaching the lens and impair vision. People with cataracts lack sharp images in their vision.

This is because light cannot pass through the lens, which helps form a sharp image on the retina.

When fuels are burned, A high-temperature exothermic redox chemical reaction takes place between a fuel and an oxidant, often atmospheric oxygen, producing oxidized, generally gaseous compounds in a mixture known as smoke.

Combustion is frequently a complex series of basic radical reactions. Endothermic pyrolysis converts solid fuels like wood and coal into gaseous fuels, whose combustion provides the heat needed to make more of them.

The heat produced by combustion is frequently intense enough to produce blazing or flame-like incandescent light. A basic example is the interaction of hydrogen and oxygen producing water vapor, which is often used to power rocket engines. This reaction produces 242 kJ/mol of heat and so decreases the enthalpy.

High oxidation potential oxidants for combustion include ambient or pure oxygen, chlorine, fluorine, chlorine trifluoride, nitrous oxide, and nitric acid. For example, hydrogen burns in chlorine to generate hydrogen chloride, with the characteristic heat and light liberation of combustion.
