Answer:
Evolution means change in the physical features of an organism.
Explanation:
Evolution means change in the physical features of an organism. Evolution occurs in the population of an organisms due to various factors such as mutation, non-random mating and natural selection. Nonrandom mating occurs when an organism prefer mating with particular superior organisms or with the similar organism. Mutation in the genetic makeup of an organism is also responsible evolution. this mutation occurs when an organism experience ultraviolet radiation from the sun, or also occur if an error in DNA during cell division. Gene flow is also known as gene migration is the transfer of genetic material or traits from one population to another when the organism is migrated to another environment. Some organisms are selected naturally because they have the potential to survive in that environment so they survive and that doesn't adopt itself to the environment, it will extinct from the environment.

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.

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
Answers
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.
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
Answers
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.

How to write 778,000,000 in scientific notation
Answers
To answer the question what is 77800000 in scientific notation let’s recall how to convert 77800000 to scientific notation as detailed on our home page.
When you split the number 77800000 into a coefficient and a power of 10 you do get 77800000 in exponential form, but there is an indefinite number of possibilities.
As you probably want 77800000 in normalized scientific notation, the coefficient or significand of 77800000 in scientific notation must be in the interval [1,10[.
As there are many ways to express 77800000 in scientific notation, in this post we mean 77800000 in normalized scientific notation, unless stated otherwise. Therefore:
77800000 in scientific notation = 7.78 × 107.

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
Answers
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.
