Answer:
Soil Layers. Soil is composed of both biotic—living and once-living things, like plants and insects—and abiotic materials—nonliving factors, like minerals, water, and air. Soil contains air, water, and minerals as well as plant and animal matter, both living and dead. These soil components fall into two categories.
humans developed antibiotics to fight bacterial infections however some antibiotics are no longer effective in killing the bacteria than once killed how does the theory of evolution explain this antibiotic mutated the bacteria which allowed resistance develop
Answer:
Changes in genetic makeup occurs with the passage of time.
Explanation:
Antibiotic cause mutation in the bacteria which allowed to develop resistance in the bacteria. This resistance and change in the genetic makeup obeys the theory of evolution which states that all species are changed gradually with the passage of time. The genetic makeup of bacteria also changes with the passage of time and attain resistance due to regular application of antibiotics so due to this resistance, the antibiotic can't work on the bacteria.

What evidence is there that the 15 species of finch all evolved from one common ancestor?
All of them evolved from one rooted species, which colonized the islands only a few million years ago. This process, whereby species evolve rapidly to exploit empty eco-space, is known as adaptive radiation.
What is evidence of common ancestry and how do they explain evolution?Homologous structures provide proof for a common origin, while analogous structures show that similar selective pressures can produce similar adaptations. Alikenesses and differences among biological molecules can be used to determine species' relatedness.
Thus, adaptive radiation is one of the reasons.

In Death Valley, California, there are several ponds that are formed in various areas of the desert. Each pond contains its own species of fish unique to the pond it lives in.
Answer:
Geographical isolation.
Explanation:
Due to Geographical isolation, there are unique species present in each pond because they can't inter-breed with one another due to no way of movement to one another location. These unique fish species are geographical isolated from one another which is also responsible for its uniqueness. If they are not Geographical isolated so these fishes mate with each other and their uniqueness will disappear so we can conclude that geographical isolation is responsible for the uniqueness of fish species in each pond.

◾️they grow quickly.
◾️they make a quick profit for farmers
◾️they are used in a variety of products
Answer:
"They are used in a variety of products" or "They make a quick profit for farmers."
You would say its "They grow quickly" but I took the examine and it was incorrect.
Explanation:
This was pulled straight out of the lesson
Agriculture, or farming, is the largest driver of deforestation in which vast areas of natural forest are burned or cleared to raise cattle or grow crops. Usually forests are burned to quickly make the land available for planting. Sometimes fast growing crops, like palms and soybeans, are planted on lands cleared of their forests; these crops make a quick profit for the farmers. Palm oil and soy are used in a wide array of products ranging from toothpaste, chocolate, animal feed, and cosmetics.
Why do you think these crops are sometimes called "cash crops"?
Cash crops like palm and soy grow quickly and make money fast.
The following are reasons that crops like soybean and palm are called cash crops:
They make a quick profit for farmersThey are used in a variety of products.So, the correct options are C and D.
What are Cash crops?Unlike subsistence crops, which are grown to supply the basic needs of the farmer and his family, cash crops are agricultural products grown with the intention of being sold for profit. Cash crops are often traded on international markets and are generally produced on a large scale, often employing industrial agricultural techniques.
Cereals, fruits, vegetables, and industrial crops such as cotton, tobacco, and rubber can all be considered cash crops. Soybeans, coffee, cocoa, tea, palm oil and sugarcane are some of the most popular cash crops.

PLEASE HELP!!!! You discover a new protist species. It has chloro-
plasts and vacuoles and moves using a flagellum.
How would you classify the way that it gets energy?
Is it an autotroph, heterotroph, or both? Explain
your answer.
Answer:
Autotroph
Explanation:
An autotrophic organism is any organism that is capable of synthesizing its own food either by using sunlight (photosynthesis) as an energy source or chemicals (chemosynthesis). An organism capable of photosynthesis must possess CHLOROPLAST (CHLOROPHYLL), which is responsible for capturing sunlight in the cell and also harbors the photosynthetic process.
According to this question, a newly discovered protist is said to have chloroplasts and vacuoles and moves using a flagellum. Due to the fact that this protist possess CHLOROPLAST organelle, it means it can perform photosynthesis, which is one of the ways an autotrophic organism synthesizes it's food. Hence, the organism is AUTOTROPHIC.

Which of these energy transformations is taking place in the chimpmunk when its cells use the plants sugars to carry out cell processes?
Answer:
This question lacks options, the options are:
A. chemical energy -> kinetic energy
B. kinetic energy -> solar energy
C. solar energy -> chemical energy
D. kinetic energy -> nuclear energy
The correct answer is A.
Explanation:
All living organisms need energy to carry out certain processes in their body. This energy is obtained in form of ATP (chemical energy) when their food molecules is broken down via a process called CELLULAR RESPIRATION.
This chemical energy (ATP) is needed to perform cellular processes in the body. According to this question, a chipmunk (animal) will utilize the energy it derives (ATP) from breaking down plant sugars to carry out its cell processes. This means that it will transform CHEMICAL ENERGY → KINETIC ENERGY.
Note that, kinetic energy is the energy due to motion in the Chipmunk.
