The development of pesticide resistance in crop pests is an example of?
Pesticide resistance in crop pests is an example of natural selection. Individuals with gene versions that confer pesticide resistance are more likely to survive and reproduce, leading to the increase of pesticide resistance in the pest population over time.
Explanation:Pesticide resistance in crop pests is an example of natural selection. When pesticides are repeatedly applied to a pest population, individuals with gene versions that confer pesticide resistance are more likely to survive and reproduce. As a result,
pesticide resistance becomes more common in the population over time. This phenomenon is observed in over 400 insects and mite pests and more than 70 fungal pathogens that have become resistant to one or more pesticides.
Which process is the opposite of inbreeding
The opposite of inbreeding would be hybridization, because it consists of two different types of animal conceiving a child.
The opposite of inbreeding is outbreeding, which involves breeding individuals who are unrelated or less closely related. Outbreeding helps maintain genetic diversity and can be achieved through practices such as crossbreeding or bringing in unrelated individuals. Examples of outbreeding can be seen in agriculture where farmers practice outbreeding to improve crops or livestock.
Explanation:The opposite of inbreeding is outbreeding. Inbreeding refers to the breeding of individuals who are closely related, such as siblings or parent-offspring. In contrast, outbreeding involves breeding individuals who are unrelated or less closely related.
Outbreeding helps maintain genetic diversity within a population and reduces the risk of inheriting harmful traits caused by recessive alleles. This can be achieved through practices such as bringing in unrelated individuals from other populations or species, or practicing crossbreeding between different individuals.
For example, in agriculture, farmers often practice outbreeding to improve crops or livestock by introducing genetic diversity through crossbreeding or selective breeding with unrelated individuals of the same species.

Why would damage to the nervous tissue in the spinal cord lead to paraysis
Evolution occurs by a process called ______. a Mixing b Artificial selection c Natural Selection d Artificial Insemination
Evolution occurs through a process called natural selection. The correct option is c.
What is natural selection?Natural selection is the method by which a species adapts to its surroundings. Natural selection causes evolution when individuals with particular traits have a better chance of surviving than those who are not able to adjust to the changes, and these traits are handed on to succeeding generations.
The strongest survive through natural selection, and the most favored traits endure through evolution. (Finches in the Galapagos, as an example. Birds with color preferences for their nests are one example of evolution.
These connected forces changed the genomes of the adapted organisms, giving them specific advantages over the less adapted ones.

what is codon. what does it do
A codon is basically a "word" in the genetic code.
Let's start at the base. A base is the smallest unit of information in genetics. It is a chemical represented by either A, T , C, G or U.
These genetic "letters" are combined into "words" which are called codons. What is useful is that each codon is only made of 3 bases. You'll have CCT, GAT, TTA etc. So what do these words represent? Well they can be instructions, like START or STOP, but usually they represent an amino acid, the LEGO building blocks of proteins. There are around 20 AAs but a bit of maths tells us we have a lot more codon combinations than AAs. This means we have some synonyms where several codons can represent one AA.
To take the analogy further, the codons combine into "sentences" and then "chapters". The chapters are a gene, usually instructions for a complete protein, but some of the sentences are useless and will be ignored when translating into a protein.
Then we have the "Book" which is the chromosome. The reason I like to think of it as a book is that at this point it is a contained unit, a massive molecule. You can separate up your books and even lend one to a friend, but you can't do that with a chapter unless you destroy the book.
Finally you have you "library" or genome. It's not a big collection, 46 books in total, and in fact you have 2 copies of each. It's like inheriting 2 sets of encyclopaedias from your parents. They both have the same information, it is just explained in different ways.
And there is my book analogy of genetics. It's not perfect but works when used on small children.
explain how triose phosphate is produced and used in the chloroplasts of a plant.
Triose phosphate is produced in chloroplasts through the Calvin cycle in photosynthesis. One molecule is exported for other compounds, and the rest are used to regenerate RuBP.
Explanation:Triose phosphate is produced in the chloroplasts of a plant through the Calvin cycle during photosynthesis. During the regeneration stage of the Calvin cycle, three molecules of triose phosphate are produced from six molecules of G3P (glyceraldehyde-3-phosphate). One molecule of triose phosphate is exported and used in the cytoplasm to form other compounds needed by the plant, while the remaining five molecules are used to regenerate RuBP (ribulose-1,5-bisphosphate), which allows the system to continue fixing carbon dioxide.

Which fator can decrease the rate for chemical reactions . A. Low activation energy ,B.hight pressure ,C.low temperature.D.high concentration of reactants
Low temperature will slow the chemical reaction.
A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Classically, chemical reactions encompass changes that only involve the positions of electrons in the forming and breaking of chemical bonds between atoms, with no change to the nuclei and can often be described by a chemical equation.
C- Low temperature
When you lower the temperature, the molecules are slower and collide less. That temperature drop lowers the rate of the reaction.

By what process are animal wastes and dead organisms converted to other nitrogen containing compounds ?
Answer:
Decomposing
Explanation:
When bacteria starts to break down the dead matter from organisms, this is called decomposing
Animal wastes and dead organisms are converted to other nitrogen-containing compounds through ammonification, nitrification, and denitrification, involving various microorganisms that complete the nitrogen cycle.
Animal wastes and dead organisms are converted to other nitrogen-containing compounds through a multi-step process involving different types of microorganisms. First, ammonification occurs, where bacteria and fungi convert organic nitrogen into ammonia (NH3). This ammonia then undergoes nitrification, carried out by bacteria such as Nitrosomonas, turning ammonia into nitrites (NO2) and then into nitrates (NO3). Finally, through the process of denitrification, bacteria like Pseudomonas and Clostridium convert nitrates back into gaseous nitrogen (N2), which re-enters the atmosphere, completing the nitrogen cycle.

are organisms that contain more than one cell with membrane-bound organelles and a nucleus.
eukaryotes are organisms that contain more than one cell with membrane-bound organelles and a nucleus.
Eukaryotes are organisms with cells that contain a membrane-bound nucleus and organelles. They can be unicellular or multicellular and are distinct from prokaryotes, which lack a nucleus and membrane-bound organelles. Eukaryotic cells are typically larger and more complex than prokaryotic cells.
Organisms that contain more than one cell with membrane-bound organelles and a nucleus are known as eukaryotes. These organisms can be made up of a single cell or can be multicellular. They are characterized by having a nucleus that contains the organism's genetic material and is surrounded by a complex nuclear membrane. Additionally, eukaryotic cells contain several other membrane-bound organelles, such as mitochondria, endoplasmic reticulum, and Golgi apparatus, which perform specific functions necessary for the cell's survival and operation.
Eukaryotic organisms include a vast array of life forms including protozoa, fungi, plants, and animals. A significant difference between eukaryotes and prokaryotic cells, such as bacteria, is the presence of a nucleus and other membrane-bound organelles in eukaryotes, which are not found in prokaryotes. Eukaryotic cells are typically larger than prokaryotic cells and are the building blocks of complex organisms.
