Why is meiosis important for organisms? It allows for genetic variation among organisms. It determines which genes are dominant and which are recessive. It produces genetically identical cells. It provides a means of asexual reproduction.

Genetic variation. Meiosis is the combination of 2 haploid cells so it's not asexual reproduction. Meiosis doesn't produce identical cells-mitosis does. And it doesn't determine which genes are dominant or recessive - there are equal chance of inheriting dominant/recessive genes, but the dominant one is expressed as phenotype

Which of the following statements about agricultural societies is true? a. Agricultural societies did not pollute the environment. b. Agricultural societies impacted the environment less than hunter-gatherer societies. c. Agricultural societies had a higher population than hunter-gatherer societies. d. Agricultural societies impacted the environment more than industrial societies.

The correct answer is option C. Agricultural societies had a higher population than hunter-gatherer societies.

The hunting is not a very popular profession now-a-days, but the agriculture is very common and there are many people, who are involved in the profession of the agricultural production. So, the agricultural societies have a much higher population as compared to the that of the hunter-gather societies. Also, the hunting is banned for many animals and cannot produce enough money to support the basic livelihood.

QUESTION POSTED AT 18/01/2020 - 12:31 PM

Scientific consensus supports the idea that living organisms require oxygen. Then, a scientist discovers a type of bacteria that metabolizes sulfur instead of oxygen, and thus survives in environments without oxygen. The scientist concludes that a diverse group of many different organisms could live in an oxygen-free environment. Why should are some scientists skeptical of the scientist’s results and conclusion?

The answer is that the conclusion needs to be supported by more evidence.

It is not enough to find some type of bacteria that can live in an oxygen-free environment to conclude there are many different organisms that also can. It is necessary to know what mechanisms of the organisms are responsible for such characteristics that help them  survive in environments without oxygen. There must be more evidence from different group of organisms that will confirm the conclusion.

Scientists group organisms into kingdoms by looking at specific characteristics. The characteristic of the carrot plant is eukaryotic. Organisms with eukaryotic cells are whose cells contain a nucleus and other organelles enclosed within membranes.

Explanation:

Eukaryotes are organisms whose cells have a nucleus surrounded by membranes, unlike prokaryotes. Eukaryotic cells are larger than prokaryotic cells and have a “true” nucleus, membrane-bound organelles, and rod-shaped chromosomes. The nucleus houses the cell's DNA and regulates the structure of proteins and ribosomes.

Producers are the most important biotic factor in an ecosystem. a. True b. False

Answer;

The above statement is True.

Explanation;

-Biotic factors are the living components of an ecosystem and are sorted into three groups: producers or autotrophs, consumers or heterotrophs, and decomposers or detritivores.

-Producers are living things within an ecosystem that make life possible for all other organisms. This is because they produce something very important. They are important parts of an ecosystem. Producers are the green plants. They make their own food. Consumers on the other hand are animals and they get their energy from the producers or from organisms that eat producers.
