Answer:
Thomas Malthus on his essay on population.
Explanation:
Malthus concluded that human population grow faster than the available resources in their environment.However,no matter how this population increases,selection pressure like famine,natural disasters,always keep the population in check,thus maintaining the population size within moderate levels.
He believed the weakest in the population (with little resistance to the selection pressure) will die,thereby reducing the population, encouraging the survival of the fittest,and stabilizing and preventing expulsion.
Darwin, assumed that the surviving organisms in the population must have inherited certain characteristics/traits from their parents,which make them to resist the selection pressures.He called the surviving ones the survival of the fittest by natural selection.

Which substance's cycle can be disrupted by the addition of fertilizer and can result in eutrophication?
nitrogen
water
oxygen
carbon
Answer:
Oxygen
Explanation:
When excessive minerals(N.P.K) and nutrient are released into the body of water from leaching and other sources,(detergents,fertilizers application,sewage etc )which leads to corresponding increase in the population of algae(algae boom)the condition is called Eutrophication.
This disrupts the oxygen cycle because,the increased algae population(algae boom) makes use of available oxygen in the habitat for respiration.With continue supply of the nutrients,the population continue to rise.The competition for oxygen with other fauna leads to shortage of available oxygen,and therefore death of these fauna,and later of the algae.
The decomposing bacteria,also used the fragment pf oxygen to decompose the algae and other dead fauna,further reducing the oxygen levels of the water,with increase in water pollution.
Answer:
nitrogen because...
Explanation:
When nitrogen and phosphorus from fertilizer are carried in runoff to lakes and oceans, they can cause eutrophication, the overgrowth of algae.
The current taxonomic system that taxonomists use (and that we are using during our Summer session) follows a taxonomic scheme that recognizes _____ (a number) Kingdoms in the Domain Eukarya (also spelled Eucarya).
Answer:
The correct answer is - 4 kingdoms.
Explanation:
According to the current classification or taxonomic system used by many taxonomists is the modern Linnean classification system and according to this, there are four kingdoms Protista, Fungi, Plantae, and Animalia in the domain eukarya. there are two more kingdoms in prokaryotes that are monera and archaebacteria
Thus, the correct answer is - 4 kingdoms.
Assume that the point mutation and deletion mutation are not in overlapping regions of the phage genome. What phage recombinants would you expect if a crossing-over event occurred between the regions of the two mutations?
Answer:
A recombinant phage containing both mutations.
Explanation:
A recombinant organism is produced by recombination, which is a genetic phenomenon associated with the repair of double-strand breaks in DNA. In genetic research, recombinant organisms are used to investigate target gene expression. The process of DNA repair may be associated with two different pathways: homologous recombination (HR) and non-homologous end-joining (NHEJ). In this case, the recombinant phage contains no overlapping mutations (i.e., both deletion and point mutations), thereby carrying the desired genetic combination.

The research done by Soto, Sonnenschein, and Hunt reveals how chemicals could affect the production of gametes, thereby affecting the passage of genetic traits down from one generation to the next. Which of the following mechanisms are responsible for the generation of genetically diverse offspring?
a. independent assortment of chromosomes during meiosis I
b. independent assortment of chromosomes during meiosis II
c. genetic recombination
d. crossing over
Answer:
a,c,d
Explanation:
Crossing over occcur when genetic material is exchanged between homologous chromosome this leads to formation of new genes that creates diversity.
homologous chromosome assort imdependently i.e seperate from each other leading to the formation of an entirely new gene that creates diversity.
Genetic recombination when gene recombines together to produce a unique type. It occurs between different species.

The graphic below shows how photosynthesis and cellular respiration are related.
Answer:
Humans and animals both are depend on the cellular respiration. When o2 is released by plant is inhaled by animals and humans and exhale carbon dioxide.
Explanation:
Oxygen is stored during photosynthesis and produce oxygen in cellular respiration. Carbon dioxide and water are used in photosynthesis released cellular respiration. The energy that is releases during photosynthesis is stored by the process of cellular respiration. Glucose is broken down during the process of photosynthesis, to produce the food in cellular respiration.
The relationship shows that both are reactant to each other. The photosynthesis used sunlight , water and carbon dioxide to produce the glucose. The cellular respiration used that oxygen and water to produce carbon dioxide.

Wheat varieties are usually purelines because Group of answer choices there is little available genetic variation in wheat germplasm breeders do not want farmers to save their own seed the potential for exploiting hybrid vigor in wheat is limited wheat is predominantly outcrossing
Answer:
little available genetic variation
Potential for exploiting hybrid vigor in wheat is limited wheat is predominantly outcrossing
Explanation:
Pure lines are varieties with little genetic variation. Pure lines are generated from crops that have undergone selection to the point of uniformity this is done to reduce variation that may occur genetically and to get varieties that are the same genetically.
Pure lines are they are the same genetically with no segregating genes. variation or changes in pure lines is mostly associated with the environment. wheat is an outcrossing crop generating a pure line will help have good vigour as selection would have been done to generate varieties that are strong and high yielding.
In four to eight sentences, trace the flow of carbohydrate macromolecules through a rain forest ecosystem. State how the marcomolecules are produced, how they are passed along, and what they are eventually used for. In your answer, give specific examples of macromolecules.
Answer:
Carbohydrate is a big source of energy for all living organism on this planet.
Explanation:
The carbohydrate which is a macro-molecule is produced by the producer such as trees and shrubs etc in the process of photosynthesis. These carbohydrates transfer to the primary consumer such as monkey who eat these plants. When the secondary consumer such as jaguar eat these primary consumer, this carbohydrate again transfer from one organism to another organism. This carbohydrate is a source of energy which is broken down in the stomach into glucose and this glucose is absorbed by the cells and releases energy by mitochondria in the form of ATP. This energy is used in various activities such as walking, running and breathing etc. Carbohydrate, proteins and fats are the examples of macro-molecules.
Answer:
hi

A discrete, locally folded unit of protein tertiary structure usually having a specific function best describes __________. A discrete, locally folded unit of protein tertiary structure usually having a specific function best describes __________. a domain a motif a complex quaternary structure
Answer:
a domain
Explanation:
The domains are the basic units of the proteins, they are polypeptide segments (about 30 -200 amino acids) that have a defined tertiary structure and play specific biological functions including, for example, enzymatic and structural activities. Protein domains are evolutionary conserved, it means that these polypeptide segments can be found in phylogenetically related species and share sequence homology. Examples of protein domains include the zinc finger and the helix-turn-helix domains which are involved in protein-DNA interactions of transcription factors.
Which of the following wavelengths of light are able to penetrate the Earth’s atmosphere and best viewed through a reflecting telescope?a. Radio Waves b. Infrared Waves c. Visible Light Wave d. Ultraviolet Light Waves Clear my choice
Answer:
c. Visible Light Wave
Explanation:
The electromagnetic radiation spectrum can be divided into seven types of wavelengths of light, which are classified according to the decrease in wavelength and the increase in energy and frequency: 1-radio waves, 2-microwaves, 3-infrared light, 4-visible light, 5-ultraviolet, 6-X rays and 7-gamma rays. The atmosphere is not permissible to all types of wavelengths of light, thereby acting as a natural barrier that protects against harmful radiation waves. All the range of visible light can penetrate the Earth's atmosphere, while most radio waves can penetrate through this barrier. Finally, only some wavelengths of infrared and ultraviolet radiation can pass through the atmosphere.
Answer:
yall stoopid its radio waves :D

Mention five similarities between art and philosophy.
Please this is URGENT!! I'll thank u so much if u help me.
Answer:
The five major similarities between the given instances are described below.
Explanation:
Art seems to be about men's job of making things or even just meanings. Philosophy should be about what life, reality, and wisdom represent.Philosophy couldn't be incorrect, just as art can't be that bad. That is an incoherent term. The argument that theory goes around through communities or never comes to a satisfactory conclusion has always been the main topic including its argument. That's only because philosophy becomes interpreted as if it were science rather than art.Art and Philosophy will say, I'm making this. Those would be the ideal illustration of the intelligence of man.Art seems to be an undertaking that aims at creating something aesthetically intriguing and that would be valued for its attractiveness or expressive strength. Philosophy approaches art from such a situational-perspective, i.e., attempting to ascertain whatever was rather than concentrating on a single piece of art or observing general trends.Why does the Cenozoic Era have epochs, but the Mesozoic and Paleozoic Eras do
not?
\The common use of epochs during the Cenozoic helps paleontologists better organize and group the many significant events that occurred during this comparatively short interval of time. Knowledge of this era is more detailed than any other era because of the relatively young, well-preserved rocks associated with it.
