Answer: The answer is A,
Explanation:
Answer:
C. Autotrophs fix carbon and produce oxygen for heterotrophs, which produce carbon dioxide for autotrophs.
Explanation:
Autotrophs are organisms that conduct photosynthesis. One of the products of photosynthesis is oxygen, which is released into the air. Heterotrophs then take in this oxygen and give out carbon, which then the plants take in and use. This cycle goes endlessly on and on.

What steps are involved when a planarian needs to generate new cells
Answer:
Using this technique, which they termed 'chemical amputation', the team induced lesions in planaria and investigated which genes were activated over the course of the regeneration process. The pharynx lacks neoblasts, but cells near the wound quickly start dividing and regenerate the amputated organ.
The steps which are involved when a planarian needs to generate new cells include the different stages of regeneration.
What is Regeneration?Regeneration in the planarians depends on the presence of stem cells called as neoblasts. These newly formed cells are distributed throughout the body and, when part of the worm has been amputated, these parts are activated to reform the tissues which have been removed.
Planarians also use this extraordinary regenerative ability to reproduce asexually. Through the process of transverse fissions, planarians which anchor their tails and also essentially pull themselves apart from each other, resulting in two fragments which include one head and one tail that will regenerate into two genetically identical worms.

Spontaneous generation, the claim that living things can come from nonliving things, was an integral part of the theory of how life began and evolved for many years. In the 1600s, Francesco Redi was the first scientist to try to disprove spontaneous generation. Louis Pasteur, in 1859, finally disproved this claim with scientific evidence.
Answer:
The answer is Scientific thoeries are a culmination of many scientific investigations drawing together all current evidence.

ChloroplastsCell wallsAutotrophicWhat are protists?Protists are a diverse group of eukaryotic organisms that are not animals, plants, or fungi. They are typically unicellular but can also be multicellular or colonial. Protists can be found in a variety of environments, including freshwater, marine, and soil, and can be free-living or symbiotic. They are an ancient group of organisms, and some of the earliest eukaryotes were likely protists.
The diversity of protists is immense, and they exhibit a wide range of characteristics and behaviors. Some protists are photosynthetic, using pigments like chlorophyll to capture sunlight and convert it into energy. Others are heterotrophic, consuming other organisms or organic matter. Some protists are capable of moving through their environment, using structures like flagella, cilia, or pseudopodia to propel themselves. Because of their diversity and importance in many ecosystems, protists are an important area of study in biology.

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.
Define biodiversity and the importance of diversity in ecosystems. How could humans harm an ecosystem's biodiversity?
Answer:
Biological diversity - or biodiversity - is the term given to the variety of life on Earth and the natural patterns it forms. The biodiversity is the fruit of billions of years of evolution, shaped by natural processes and, increasingly, by the influence of humans.
Explanation:
Biodiversity is important to humans for many reasons. ... Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services. If no changes are made in the ways humans use resources on earth, there will continue to be a degradation of biodiversity until human lives can no longer be sustained. Humans affect biodiversity by their population numbers, use of land, and their lifestyles, causing damage to habitats for species.
