Answer:
B
Explanation:
Because the excessive use of fertilizer can affect the growth of the bean plant
Final answer:
Observations where treated bean plants grew taller than untreated ones support the conclusion that (option B) fertilizer can affect bean plant growth.
Explanation:
Students observed that bean plants treated with fertilizer were taller on average than those not treated with fertilizer. This observation lends support to the conclusion that (option B) fertilizer can affect the growth of bean plants. While it is possible that not all plants respond to fertilizer in the same way, the data provided specifically shows that the treated bean plants were taller. This suggests that fertilizer has a positive effect on growth, at least for this type of bean plant. It does not, however, support the conclusion that survival is dependent on fertilizer or that only fertilizer can increase plant size, as this would require further testing and data.

Which of the following statements describes an example of phenotypic plasticity?
Choose 1 answer:
A.A person has brown hair before applying hair dye, and purple hair afterwards.
B.Dog cell develops a mutation that changes the sequence of a gene, resulting in the growth of
a tumor
C.A cactus grows long spines in both drought and non-drought conditions.
D.An arctic fox is brown in summer and white in winter
Final answer:
The example that best illustrates phenotypic plasticity is the arctic fox changing its fur color from brown in summer to white in winter in response to environmental changes. The correct answer is C. A cactus grows long spines in both drought and non-drought conditions.
Explanation:
The phenotypic plasticity is the ability of an organism to change its phenotype in response to changes in the environment. Looking at the provided options, the example that describes phenotypic plasticity is the arctic fox being brown in summer and white in winter. This is because the arctic fox changes its fur color based on seasonal changes, which is a clear response to a change in its environment and is not due to any genetic mutation or artificial alteration.
Some other examples of phenotypic plasticity include plants changing color with different soil acidity or exposure to light and temperature changes. In animals, examples like the crystalline iceplant adjusting its water needs based on environmental conditions or the multiple alleles determining coat color in rabbits showcase how phenotypes can vary under different environmental influences or genetic contexts.
An environmental factor that causes a population to decrease is called a ____________.
Answer choices:
Limiting factor
Competition
Carrying capacity
Symbiosis relationship
Answer:
It is limiting factor and competition.
Final answer:
An environmental factor that reduces a population size is a 'limiting factor'. These include insufficient resources such as food or space, and also factors like disease and predation that can impede population growth and help maintain the population at its carrying capacity.
Explanation:
An environmental factor that causes a population to decrease is called a limiting factor. Limiting factors are elements in the environment that can lower the population growth rate by reducing resources or introducing challenges that affect survival rates. Common limiting factors include low food supply, lack of space, insufficient water or nutrients, disease, and predation. If more and more individuals are added to an environment without an increase in essential resources, not all can survive, similar to a scenario where 24 people try to share 12 hamburgers and eventually, not everyone can eat. Therefore, when a population faces limiting factors, growth is no longer exponential. Instead, it follows a logistic growth pattern, also known as S-curve, where the population levels off at a carrying capacity, which is the maximum population size that the habitat can sustain.

Explanation:
Which of the peas traits yellow or green, is dominant? Explain your answer
Final answer:
In pea plants, the yellow seed color (Y) is dominant over the green seed color (y); thus, crossing true-breeding yellow and green pea plants will result in F1 offspring all having the dominant yellow phenotype.
Explanation:
Among the traits for pea seed color, the yellow trait (Y) is dominant over the green trait (y). This is evidenced by the cross of true-breeding parents in the P generation, where plants with the yellow phenotype (YY) are crossed with plants that have the green phenotype (yy).
The result of this cross produces F1 offspring that are all heterozygous (Yy) and demonstrate a yellow phenotype, indicating that yellow is dominant as it masks the expression of the green trait.
When you perform this cross, you would expect the F1 offspring to all possess the yellow seed phenotype. This is confirmed in a Punnett square analysis, which predicts the genotypes of the F2 generation, showing a 3:1 ratio of yellow to green phenotypes in the F2 offspring from the F1 heterozygotes.
The F1 offspring receive one allele for yellow seed color (Y) from the yellow parent and one allele for green seed color (y) from the green parent. However, since yellow (Y) is dominant, all F1 offspring display the yellow phenotype despite being heterozygous.
Fundamental differences in the cell, the basic unit of life, allow for the broadest classification of all living organisms into three domains: Bacteria, Archaea, and Eukarya. Which of the following can organisms NOT be classified on?A: Ability to obtain nutrients B:Mode of reproduction C:Physical characteristics D:Lacking a nucleus
Answer:
Physcical characteristics
Explanation:
Since the question has to do with fundemental classification then it cant have anything to do with physical classificaton.
Physical characteristics alone cannot be used to classify organisms. Therefore, option C is correct.

Which is the greatest threat to survival of large predator species, like mountain lions and tigers
A) loss of other predator species
B) Global climate changes
C) loss of large wilderness areas
D) animal diseases
Answer:
B) Global climate changes
Explanation:
The greatest threat to the survival of large predator animals such as mountain lions and tigers is the change occurs in climate. Due to climate change, the temperature of the whole world increases. On mountains, the temperature is very low which is favorable for the growth of mountain lions and tiger. But increase occurs in the temperature of these mountain areas due to global warming, these animals die.
B) Global climate changes
Climate change has produced a number of threats to wildlife throughout our parks. Rising temperatures, lower many species survival rates due to changes that lead to less food, less successful reproduction, and interfering with the environment for native wildlife.For example, as temperatures get warmer, many plants are starting to grow and bloom earlier in the spring and survive longer into the fall. Some animals are waking from hibernation sooner or migrating at different times, too.Therefore, correct option is B.

Which seasons are shown in model B for the Northern and Southern Hemispheres? Explain your answer.
Answer:
The Northern Hemisphere is pointing toward the Sun, so it is summer in the Northern Hemisphere. The Southern Hemisphere is pointed away from the Sun, so it is winter in the Southern Hemisphere.
Explanation:
The seasons in the Northern and Southern Hemispheres are determined by Earth's tilt. In June, it's summer in the Northern Hemisphere due to more direct sunlight and longer days, while it's winter in the Southern Hemisphere. This pattern is reversed in December. Spring and autumn represent more equal sunlight distribution. But, latitudinal location also affects the intensity of seasons.
Explanation:The seasons in the Northern and Southern Hemispheres are determined by the tilt of Earth's axis of rotation. In June, when the Northern Hemisphere 'leans into' the Sun, it is summer in the Northern Hemisphere due to longer days and more direct sunlight, whereas it is winter in the Southern Hemisphere. In December, this pattern is reversed: the Southern Hemisphere receives more direct sunlight and experiences summer, while it is winter in the Northern Hemisphere.
During the spring and autumn equinoxes, both hemispheres receive equal shares of sunlight. Specific dates like June 21 and December 21 represent the summer and winter solstices, respectively, and March 21 and September 21 represent the spring and autumn equinoxes. However, the effects of seasons vary at different latitudes. Near the equator, there's less variation in seasons, whereas in the polar regions, the differences are more pronounced.

Would you expect an anima with the scientific name Rania onca to look similar to a Jaguar?
Jaguar
The jaguar (Panthera onca) is a large felid species and the only extant member of the genus Panthera native to the Americas. The jaguar's present range extends from Southwestern United States and Mexico in North America, across much of Central America, and south to Paraguay and northern Argentina in South America. Though there are single cats now living within the Western United States, the species has largely been extirpated from the United States since the early 20th century. It is listed as Near Threatened on the IUCN Red List; and its numbers are declining. Threats include loss and fragmentation of habitat.
Overall, the jaguar is the largest native cat species of the New World and the third largest in the world. This spotted cat closely resembles the leopard, but is usually larger and sturdier. It ranges across a variety of forested and open terrains, but its preferred habitat is tropical and subtropical moist broadleaf forest, swamps and wooded regions. The jaguar enjoys swimming and is largely a solitary, opportunistic, stalk-and-ambush predator at the top of the food chain. As a keystone species it plays an important role in stabilizing ecosystems and regulating prey populations.
While international trade in jaguars or their body parts is prohibited, the cat is still frequently killed, particularly in conflicts with ranchers and farmers in South America. Although reduced, its range remains large. Given its historical distribution, the jaguar has featured prominently in the mythology of numerous indigenous American cultures, including those of the Maya and Aztec.

What anatomy is the study of similarities and differences in organisms structures
Answer:
Comparative anatomy.
Explanation:
Comparative anatomy is a branch of science in which we study about similarities and differences present in different organisms. This type of study is very important for the classification of living organisms. Comparative anatomy tells us about the evolution of an organism. Scientists study DNA, embronic structure and the internal structure of species to see the evolution of different organisms.
Final answer:
Comparative anatomy is a field of biology that investigates the structural similarities and differences among various species to deduce their evolutionary relationships, using homologous and analogous structures as evidence for common ancestry and evolution.
Explanation:
Comparative anatomy is the branch of biology that studies the similarities and differences in the structures of different species. Researchers examine the structures within various organisms to determine if their features are homologous, inherited from a common ancestor, or analogous, serving similar functions but not derived from a common ancestor. Such studies provide substantial evidence for the theory of evolution, revealing how closely related different organisms might be through their shared ancestral traits. These homologous structures, like the bone patterns in the limbs of mammals, suggest a common lineage, even if the limbs now serve different functions.
To clarify, the bones in the human arm, the wing of a bird, the fin of a whale, and the forelimb of a lizard, despite their different current uses, all originated from the same ancestral structure. Thus, comparative anatomy not only highlights the diversity of life but also underscores the underlying connections between species, offering insights into their evolutionary history.
how does the photosynthesis equation and the cellular respiration equation explain why the total amount of O2 and CO2 remains the same?
Explanation:
If you look at the photosynthesis equation, it goes: [tex]6CO_{2} + 6H_{2}O + sunlight -> C_{6} H_{12} O_{6} + 6O_{2}[/tex]
Now the cellular respiration equation goes: [tex]C_{6} H_{12} O_{6} + 6O_{2} -> 6CO_{2} + 6H_{2}O + ATP[/tex]
Do you see the similarity? The only difference in these two is that sunlight is replaced with ATP in the cellular respiration equation, and we can safely assume that the energy used and released in both are the same as the rest of the equations are identical.
The balance of oxygen and carbon dioxide in the atmosphere is maintained through the cyclical relationship between photosynthesis and cellular respiration. The equations for these processes reflect their inverse nature, ensuring that the total amounts of these gases remain the same through a process of recycling and changing forms.
The equations for photosynthesis and cellular respiration are essentially the reverse of each other, maintaining a balance of oxygen (O₂) and carbon dioxide (CO₂) in the atmosphere. During photosynthesis, plants and other autotrophs take in CO₂ and water (H₂O) to produce glucose (C6H12O6) and release O₂ as a byproduct, as per the photosynthesis equation: 6CO₂ + 6H₂O → C6H12O6 + 6O2. Conversely, cellular respiration, carried out by plants, animals, and fungi, utilizes O₂ and glucose to produce energy, releasing CO₂ and H₂O in the process, with the cellular respiration equation being: 6O₂ + C₆H₁₂O₆ → 6CO₂ + 6H₂O.
This cyclical relationship ensures that the total amount of O₂ and CO₂ remains the same, as the substances are recycled indefinitely, changing form but never disappearing. The exchange of CO₂ and O₂ through these processes contributes to the stable levels of these gases in the Earth's atmosphere. This balance is crucial for the functioning of ecosystems, as it enables organisms to access energy either directly from the sun, in the case of photosynthesis, or from the stored energy in carbohydrates, in the case of cellular respiration.

Answer: polymerase
Explanation:
RNA polymerase is the enzyme that is responsible for the formation of new RNA. This enzyme catalyzes the linkage between the nucleotides of RNA Thus the correct option for this question would be option B.
What is RNA polymerase?RNA polymerase is the enzyme that is responsible for the formation of new nucleotides which are transcribed into RNA. These are the enzymes that are responsible for copying DNA sequences into RNA during the process of transcription.
This enzyme catalyzes the reaction and instructs them to form the nucleotide sequences for the new RNA molecule. These enzymes play a very important role during the process of transcription and bind with the template DNA strand to make nucleotides for a new RNA molecule.
Transcription is the process of making an RNA molecule from DNA. It is divided into three stages. First is an initiation where the process of transcription starts. The second one is elongation in which the formation of new nucleotides and amino acids takes place and the last one is termination in which the RNA polymerase gives instructions to stop the process.
During this, the nucleotides are transcribed and this is catalyzed by the RNA polymerase enzyme. Thus the correct option for this question is option B.
