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.
Why do you think it would be important to know that both sides of the heart receive blood at the same time? Giving Brainliest

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. The economy, environment and social welfare of a place can be affected by cash crops in both positive and negative ways.
So, the correct options are C and D.

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.
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.

Which statement describes a forest ecosystem that has not experienced any natural disasters in the past 100 years?
A.
The types of plants that grow in the forest are changing from year to year.
B.
Faster growing conifers are replacing slower growing deciduous trees.
C.
The types of plants and animals that live in the forest are reasonably stable.
D.
The number of types of animals that live in the forest is rapidly increasing.
Answer:
C) The types of plants and animals that live in the forest are reasonably stable.
The statement that describes a forest ecosystem that has not experienced any natural disasters in the past 100 years is, "The types of plants and animals that live in the forest are reasonably stable," hence option C is correct.
What is a forest ecosystem?Along with nonliving (abiotic) elements like soil, water, air, and landforms, forests also contain living (biotic) elements like trees, animals, plants, and other life things. A forest ecosystem is made up of all of these elements.
The numerous plant and animal species residing in a forest ecosystem are generally stable if it has not recently been subjected to any disturbances or natural disasters.
Therefore, plants and animals that live in the forest are reasonably stable, so this ecosystem not experienced any natural disasters.
