A student draws this model to show how humans evolved from ancestral primates. What are the pros and cons of
this model in regard to the theory of evolution? Explain how you'd make it more accurate. To create a scientifically
credible answer, use a credible website to research human evolution.
Answer and explanation:
The model designed by the student is useful to explain in a simple way the question of the evolution of the homo gender (our gender), mainly in basic education, but it may seem inconsistent at higher educational levels.
Humans and chimpanzees, according to the theory of evolution, descend from a relatively recent (about 7 million years) common ancestor.
These same species, as well as lemurs, baboons and all other primate species, share an ancestor who lived longer. Likewise, there is an even older ancestor that originated primates, bats, whales and all other groups of mammals .
The fact that chimpanzees have a DNA very similar to ours (about 98.5% similarity between code sequences) is because the successive evolutions from this common ancestor were not very drastic, besides the fact that they are in a branch more close to ours from the moment of separation of evolutionary lineages.
Exotoxins are Question 8 options: only released after a cell is damaged or lysed. proteins. lipopolysaccharides. secretions that always target nervous tissue. antiphagocytic factors.
Answer:
The correct answer is proteins.
Explanation:
The exotoxins are proteinaceous in nature, they are the toxins, which are discharged from a living bacterium and are also discharged at the time of bacterial lysis. The exotoxins harm humans, however, not all exotoxins generated harm human beings.
Some are even created to perform an essential function in bacteria physiology like regulating functions of the cell, resisting bacteriophages, or quorum sensing. The three prime kinds of exotoxins are type I exotoxins or superantigens, type II toxins or exotoxins that damage host cell membranes, and type III toxins or A-B toxins that interfere with the function of the host cell.

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.What is the cause of humanity?

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
Explanation:
Using your answers from Part 2, trace the path that energy flows in the ecosystem. What evidence does this give you about where energy in an ecosystem comes from?
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 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.

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.
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.

25 points hurry plz thank you “What is the effect of the type of food available on the frequency of different types of bird beaks?” Hypothesis: If the type of food available changes, then…____________ …because…___________
Answer:
Explanation:
...then the bird beak changes because the bird beaks are the most vital physical feature that allows birds to catch and devous its prey.
Answer:
then... the frequency of different types of bird beaks will change, because... birds with beaks that are more suited to the available food are more adapted and will be more successful over time.
Explanation:
This is linked with natural selection.
If the type of the food available changes, then the frequency of different types of bird beaks will change, because birds with beaks that are more suited to the available food are more adapted and will be more successful over time.
Evolution of beak types will be a result of the birds adapting and changing their food habits. Natural selection is the process where organisms adapt and change.

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.
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.

Asthma is a respiratory disorder that can cause the airways to temporarily constrict, or get narrower. Which function of the respiratory system is most affected by the narrowing of the airways? A. water balance B. air filtration C. heat balance D. gas exchange
Answer:
Answer is D.
Explanation:
Asthma is a chronic inflammation that affects the airways, directly affecting the gas exchange of oxygen and carbon dioxide with the blood.
What is asthma?It is a chronic disease of the lungs that inflames and narrows the airways.
Since this disease causes the airways to become inflamed and swollen, it reduces the amount of air that can move in and out of the lungs (gas exchange).
Therefore, we can conclude that asthma is a chronic inflammation that affects the airways, directly affecting the gas exchange of oxygen and carbon dioxide with the blood.
