Jenny wants to determine if a new brand name washing detergent is better than her old detergent. She washes ten dirty t-shirts with the new washing detergent. After washing, she thinks they are cleaner using the new detergent. What can she do to be sure the new washing detergent works better than the old detergent?
Answer:
The independent varible is old and new and the dependent variable is 20 T-shirts.
Explanation:
An independent variable is a variable whose value does not depend on any other factor. Whereas a dependent variable is a variable whose value depends on another factor.
Hence, in the given situation old and new detergent are independent variables as they do not depend on any other factor.
On the other hand, 20 dirty T-shirts are dependent variable because they get clean only if the detergent is strong enough.

Give an example of how the environment can influence the way genes are expressed in a plant.
Genes are the hereditary unit, which transmits the genetic information from the parent to the offspring. Human-made and environmental factors can influence the expression of genes.
How are genes influenced by environmental factors?The environment factors such as temperature, sunlight, oxygen levels, precipitation, and diet can influence the genetic expression in plants. For instance, sunlight is necessary for plants to carry out photosynthesis. The chloroplasts are the site, where light energy is converted into chemical energy. The presence of green color pigment is synthesized when the sunlight hits the chloroplasts, thus, the absence or intensity of light will control the expression of chlorophyll.Thus, environmental factors such as sunlight, water, temperature, and oxygen level influence the genetic expression in organisms.

Explanation:
Had it on my quiz
What do the colors indicate about the change in average temperature over time from 1884 to 2012
Final answer:
The colors in the temperature anomalies figure illustrate the shift in global average temperatures from 1880 to 2012, transitioning from cooler to warmer periods, indicating a notable warming trend. The visualization supports the consensus that recent decades have seen significant temperature increases, largely attributed to human activities.
Explanation:
The colors on the temperature anomalies figure indicate changes in the global average temperature over time, from 1880 to 2012. The transition from cooler colors such as blue to warmer colors like yellow, orange, and red, reflects a general trend of rising temperatures. The blue colors represent cooler-than-average temperatures, while the warmer colors indicate temperatures that are warmer than average. The black line represents a smoothed plot of these mean temperature anomalies, highlighting a clear trend towards warming over the specified period. This visualization effectively demonstrates how temperatures have shifted globally, with significant warming observed, particularly in the latter half of the 20th century and into the 21st century.
The inclusion of data from indirect indicators like tree rings, ice cores, and corals, alongside thermometer measurements, provides a comprehensive view of global temperature changes over the last two millennia. The analysis of this data shows a stark increase in temperatures in recent decades, attributed largely to human activities as evidenced by the overlapping of the black line (observed temperatures) and the brown band (climate change due to both human and natural factors) in the scientific visualization. This correlation underscores the significant impact of greenhouse gases on the planet's climate.
. Which of the following supports the theory of endosymbiosis? a. Mitochondria and chloroplasts contain their own set of DNA b. Prokaryotes are bigger than eukaryotes c,Mitochondria and chloroplasts do not contain their own set of DNA d.Prokaryotes and eukaryotes are often found living away from each other
Answer: a. Mitochondria and chloroplasts contain their own set of DNA.
Explanation:
The theory of endosymbiosis suggests that origin of mitochondria and chloroplast in eukaryotes were the individual primitive prokaryotic organisms. The mitochondrial and chloroplast DNA and protein synthesis was found similar to the bacteria. This provided the evidence for endosymbiotic hypothesis. It was determined that chloroplast as well as mitochondria divide independently in the cell where they live just like individual bacterial cell.

what is the tarsals function?
The tarsals are seven bones in the ankle that transmit body weight from the tibia and fibula to the foot. They play a crucial role in balance, shock absorption, and efficient movement. Key tarsal bones include the talus, calcaneus, navicular, cuboid, and three cuneiforms.
Function of the Tarsals
The tarsals are the seven bones that make up the ankle. The ankle's primary function is to transmit the weight of the body from the tibia and fibula to the foot. The seven tarsal bones include the talus, calcaneus, navicular, cuboid, and three cuneiform bones.
The talus articulates with the tibia and fibula superiorly, forming a joint that allows for the up-and-down motion of the foot. The calcaneus, or heel bone, is the largest of the tarsals and supports much of the body's weight when standing or walking.
The other tarsal bones (navicular, cuboid, and three cuneiforms) help to form and support the arch of the foot, which provides additional shock absorption and aids in the ability to move efficiently and maintain balance. This arch is crucial for activities like walking, running, and jumping.

Most animals can survive without food and water for a longer time than they can survive without water. Why is water so important to animals? Why can an animal survive without food for longer?
Final answer:
Water is crucial for animals due to its role in metabolic processes and temperature regulation, and unlike food, there are no reserves for water in the body. Dehydration can lead to serious health issues and death, which is why animals can survive longer without food than without water. Desert animals have adaptations for water conservation, further underscoring the importance of water for survival.
Explanation:
Importance of Water to Animal Survival
Water is so important to animals because it is essential for all metabolic processes, chemical reactions, and temperature regulation within the body. Unlike food, which can be stored as fat and utilized slowly over time, water is constantly being lost from the body through processes like urination, defecation, and perspiration, and must be replenished regularly to maintain physiological balance and prevent dehydration. Dehydration can lead to a loss of electrolytes, increase in body temperature, and even death if severe enough.
Animals are often able to survive longer without food than without water because their bodies can utilize stored energy reserves such as fat, protein, and carbohydrates to sustain basic metabolic functions. However, there are no reserves for water, and it is also needed to process these energy reserves. Additionally, some desert-dwelling animals have developed specialized adaptations to conserve water, like obtaining water from their prey or internal storage mechanisms.
Hydration is crucial in maintaining life and health for animals, and the lack of water intake is more immediately life-threatening than the lack of food. The survival rule often cited by survivalists, stating that one can survive without food for weeks but only days without water, illustrates the critical role water plays in survival.
What is a solar eclipse? (4 points)
A. A solar eclipse is when the moon and the sun are on opposite sides of the Earth.
B. solar eclipse is when the moon is on the far side of the sun.
C. solar eclipse is when the moon blocks the sun's rays from reaching the Earth.
D. A solar eclipse is when anything blocks the sun's rays from reaching the Earth.
A solar eclipse is when the Moon blocks the Sun's rays from reaching the Earth. The Moon must be precisely aligned with the Sun and Earth. There are total and partial solar eclipses, depending on whether the Moon's shadow completely or only partially blocks the Sun.
A solar eclipse occurs when the Moon moves between the Sun and Earth, casting a shadow on Earth, and temporarily blocking the Sun's rays from reaching Earth. The correct answer to the student's question is (C). A solar eclipse is when the moon blocks the sun's rays from reaching the Earth. During a total solar eclipse, the Moon's umbra (the darkest part of its shadow) intersects with Earth's surface and completely obscures the Sun's light from view in a small area, allowing observers to see the Sun's corona. If only part of the Sun is covered, resulting in some sunlight still reaching Earth, it is called a partial solar eclipse. Solar eclipses are relatively rare because they require the Sun, Moon, and Earth to be precisely aligned in the same plane, known as the ecliptic.

Predict how unfavorable abiotic and biotic factors affect a species
Unfavorable abiotic and biotic factors can severely impact species by altering habitats, limiting resources, and affecting net primary productivity, which can threaten survival and reproduction of plants and animals.
Explanation:Impact of Unfavorable Abiotic and Biotic Factors on a SpeciesUnfavorable abiotic factors, such as extreme temperatures, low rainfall, high salinity, and insufficient sunlight, can drastically affect a species by altering its habitat, reducing its food resources, limiting its water supply, and challenging its survival and reproduction. Biotic factors like competition, predation, and disease also play a critical role in shaping a species' ability to thrive. For example, in aquatic environments, high salinity and low light levels due to algal blooms can hinder the survival of freshwater species. In contrast, on land, poor soil quality and extreme climate conditions can affect plant growth, which in turn influences the animal populations that depend on those plants for sustenance.
Net primary productivity is also influenced by abiotic factors. It represents the rate at which plants convert atmospheric carbon dioxide into biomass through photosynthesis minus the rate at which they use this biomass for respiration. When conditions like sunlight and water availability are unfavorable, net primary productivity declines, leading to a decrease in available energy and resources within an ecosystem.

If a star is considered medium sized it is
about the size of our sun
about half of the size of our sun
about twice the size of our sun
at least five times the size of our sun
Final answer:
A medium-sized star is about the size of our Sun, which is approximately 1.4 million kilometers in diameter. Most nearby stars are of similar size, and the Sun is brighter and more massive than about 80% of the stars in the Galaxy.
Explanation:
When considering the size of a medium-sized star, one can generally refer to a star that is about the size of our Sun. The Sun itself has a diameter of approximately 1.4 million kilometers. Most nearby stars have typical diameters around this scale, fitting the definition of a medium-sized star. However, there is a diverse range of star sizes, with some much smaller and others much larger than our Sun.
Various measurements and observations indicate that while there are exceptions, a significant number of stars fall within the spectrum of being medium-sized, implying sizes that are quite similar to our Sun. Stars significantly more massive than the Sun are quite rare within our local cosmic neighborhood; within 30 light-years of the Sun, none exceeds four times the mass of the Sun.
The Sun is also more massive than most of the stars in our vicinity, being brighter than about 80% of the stars in the Galaxy, further underscoring its qualification as a medium-sized star. Therefore, when referencing a medium-sized star, the size of our Sun serves as an apt comparison.

What is most likely to result immediately after a rainforest in Brazil is clear-cut?
A secondary succession
B primary succession
C a climax community
D increased biodiversity
Answer: A. secondary succession
An ecological succession is a phenomena which involves gradual series of events which brings changes in the biotic community of the ecosystem with respect to changes in the non- living factors such as soil, water, natural calamity like (forest fire, drought, flood) and time until the ecosystem attains stability. Secondary succession occurs in an area which was previously colonized by floral and faunal species but was disturbed by natural or man-made calamity like forest fire, clear-cut, drought, flooding.The ecosystem again attain colonization due remains of biological species and suitable abiotic factors such as soil, water, weather. Secondary succession is most likely to occur immediately after a rainforest in Brazil is clear-cut as secondary succession facilitates quicker compensation for damage and loss in an ecosystem.
Which type of limiting factor affects a large population more than it affects a small population?
density dependent
density independent
population dependent
population independent
Answer: density dependent
Limiting factor is a resource or environmental condition which limits the growth, abundance or distribution of population of species in an ecosystem. A limiting factor can be living or non-living affecting the size of the population of species in an ecosystem. Density dependent limiting factor causes decline in population per capita growth with increasing population density. Density dependent limiting factors are mostly biotic (living) rather abiotic (non-living).
Density dependent limiting factor will affect a large population more than it affects a small population because of the following reasons:
1. Competition: When a population attains high density, the members of the population compete for available resources like food, shelter, water, mates and other resources required for survival and reproduction. The competition for resources will limit the members in the population.
2. Predation: Larger population may attract more number of predators. Therefore, density in this case will result in limitation in population size.
3. Disease: When more number of individuals living in the same locality, there are chances of transmittance of diseases, hence, will result in decrease in population.
4. Accumulation of waste: High population density can lead to accumulation of biological wastes, which can contaminate the living environment, hence can limit population size.
