Which idea associated with relative dating helped inspire Charles Darwin's work on evolution?
Answer: The idea that the earth is extremely ancient.
Explanation:
Charles Darwin was a British naturalist who worked on the organic evolution of living organisms and in his books outlined how present-day organisms evolved from earlier, different species.
Evolution is an extremely slow process. It is difficult to obtain direct evidence of evolution in action. However, scientist including Charles Darwin, have from many fields gathered a great deal of indirect evidence that supports the theory of evolution. This evidence comes from many sources which include the FOSSIL RECORDS.
The history of life on earth is recorded in fossils (remains of organisms preserved mainly in earth's sedimentary rocks). Scientist can determine the age of rocks in which fossils occurs by using RELATIVE DATING. This method give a geological time scale, showing earth's age ( as measured by dating it's rocks), and tracing the history of life on it.
Therefore the idea that the earth is extremely ancient is associated with relative dating which has helped inspire Charles Darwin's work as an evidence on evolution.

What does the Greek Root "pro" mean?
Answer:
The prefix pro- primarily means “forward” but can also mean “for.” Some words that the prefix pro- gave rise to are promise, pro, and promote. When you, for instance, make progress, you are stepping “forward,” whereas if you give the pros in an argument, you are speaking “for” something by stating its advantages.

Students are asked to make a model that shows each level of structural organization and its function in human beings. Which model should the students use to explain the hierarchy of levels of organization in human beings correctly?
Answer:
The correct answer is option A. muscle cell, muscle tissue, biceps, muscle system, and human being.
Explanation:
In humans and other mammals, there is a specific type of structural organization found in which involves fundamental units to the most exclusive level of organization. The cell is the most basic and fundamental unit of the organism's structure.
Cells joined together to form tissues like muscle cells form muscle tissues, tissues grouped with each other into organs like muscle tissue form biceps, different organs are grouped into organ systems like muscle system form from organs, and many organ systems come together to form complex organisms like human beings.
Heredity is the passage of what from parent to offspring?
a. Genetic material
b. Oxygenated blood
c. Digestive enzymes
d. Connective tissue
Answer:
A
Explanation:
Genetic material is what passes down traits and makes us look similar to our parents
When we talk about heredity, we're talking about the precise ways that genes are used to transmit traits or characteristics from one generation to the next, hence option A is correct.
What is Heredity?The instructions for creating certain proteins, which are in charge of an individual's distinctive qualities, are encoded by genes.
The youthful creation of living creatures, known in biology as progeny, can be created by a single organism or, in the event of sexual reproduction, by two organisms.
DNA (deoxyribonucleic acid), which makes up genes, contains instructions for how cells should function as well as the traits that distinguish each individual.
Therefore, each of your biological parents contributes half of your DNA to you, and you could inherit a gene mutation from one or both of them, hence option A is correct.

Which of the following is a possible path for carbon to cycle through an ecosystem?
1. Atmospheric CO2 -> animals -> factories -> fossil fuels -> plants
2. Atmospheric CO2 -> factories -> fossil fuels -> animals -> plants
3. Atmospheric CO2 -> plants -> animals -> fossil fuels -> factories
4. Atmospheric CO2 -> fossil fuels -> factories -> animals -> plants
Answer: 3. Atmospheric CO2 -> plants -> animals -> fossil fuels -> factories
Explanation:
The carbon cycle is one of the types of biochemical cycles in which carbon is recycled in atmosphere, biosphere, lithosphere, and hydrosphere in various forms. The atmospheric carbon dioxide is absorbed by the plants and they utilize it as reactant for the process of photosynthesis in which they synthesize their own food. These plants are consumed by animals further when these plants and animals die their remains form fossil fuels deep beneath the earth crust. It takes about millions of years for fossil fuels to form in the sedimentary rocks. The fossil fuels are utilized by the factories to run their machines. Again when fossil fuels burn they emit carbon dioxide gas in the atmosphere.
The following passage explains the relationship between tectonic plates and earthquakes. Which sentence states incorrect information?
Tectonic plates can push together, pull apart, or slide past each other at their boundaries. The edges of tectonic plates are not smooth, so they create friction as they move. When friction is too great for the plates to move, they can become stuck and pressure can build up. An earthquake occurs when pressure that has built up between plates suddenly is released. The buildup of pressure that leads to earthquakes only occurs at plate boundaries.
Answer:
earthquakes occur when the edges suddenly become unstuck and slip along a fault

A population of African lions share the same habitat. A small group becomes reproductively isolated
from the rest of the population (mating behaviors no longer match). What type of speciation is this?
a. Allopatric speciation
b. Sympatric speciation
C. Parapatric speciation
d. Peripatric speciation
Answer:
The correct answer is - B. sympatric speciation.
Explanation:
The allopatric speciation occurs in the population that is geographically isolated, parapatric speciation takes place due to reproductive isolation however they occupy distinct nice or habitat.
Peripatric speciation is shows resemblance to allopatric speciation in terms of preventing the exchange of genes however they occur in the small peripheral population.
Sympatric produces a reproductive barrier between the small population that shows change to the parent population.

For a specific cactus plant, cacti homologous for red flowers were crossbred with cacti homologous with white flowers. The next generation was 100% pink, then it is called as incomplete dominance as the offsprings are different from the parents.
What is incomplete dominance?Incomplete dominance is a type of inheritance where the offspring that is produced is neither like the paternal parent nor like the maternal parent but will show the different intermediate type of trait that is pink in this case. Here , the pink trait is the intermediate trait of the red and the white that is present in both of the parents, and this type of the offsprings shows different trait when they have the heterozygous states. When this two pink flowers cross then there are the production of the one red, one white and two pink flowers.
Hence, the next generation was 100% pink, then it is called as incomplete dominance as the offsprings are different from the parents.

Landforms are created through destructive forces such as weathering. Which of these is an example of physical weathering? A acid rain. B abrasion. C hydrolysis. D oxidation
Answer: C. HYDROLYSIS
Explenation: Chemical weathering occurs when water dissolves minerals in a rock, producing new compounds. This reaction is called hydrolysis. Hydrolysis occurs, for example, when water comes in contact with granite.
Landforms are created through destructive forces such as weathering, so abrasion is an example of physical weathering that is in Option B as the physical weathering is a type of weathering that involves mechanical breakdown.
What is the significance of weathering in the environment?Physical weathering is caused by physical forces, such as the expansion and contraction of rock due to changes in temperature and abrasion is a specific type of physical weathering that occurs when rock or soil is rubbed against other rock or soil. In physical weathering, rock fragments or particles are carried by water, wind, or ice, and the repeated collisions and friction caused by abrasion can lead to significant changes in the shape.
Hence, landforms are created through destructive forces such as weathering, so abrasion is an example of physical weathering that is in Option B as the physical weathering is a type of weathering that involves mechanical breakdown.
