What is reason for binomial nomenclature?

Answers

Answer:

allow people throughout the world to communicate unambiguously about animal species.

Explanation:

Every recognized species on earth (at least in theory) is given a two-part scientific name. This system is called "binomial nomenclature." These names are important because they allow people throughout the world to communicate unambiguously about animal species.

In 1998, paleoanthropologist Rick Potts published an article in The Yearbook of Physical Anthropology, a peer-reviewed journal. The article was titled “Environmental Hypotheses of Hominin Evolution.” In his paper, Potts claimed that great variations in environmental conditions over time were responsible for the adaptability of humans and the success of our species. Which would most likely be found in his paper? a review of modern human anatomical structure
evidence of changing environmental conditions, with references
the reasons competing hypotheses are wrong
his opinion of what will happen to the survival of the human race

Answers

All of the options could reasonably be a part of the paper, and all of them would make the paper better. But one of the options is actually absolutely necessary: evidence of changing environmental conditions, with references- this is the correct answer.

This is because his argumentation is based on the assumption of "great variations in environmental conditions over time "- so he has to proove that there were those variations.

Answer:

The most appropriate answer would be "evidence of changing environmental conditions, with references".

As Mr. Potts claimed that great variations in environmental conditions over time were responsible for the adaptability of humans and the success of our species in his paper, he must have mentioned evidence of changing environmental conditions with references.

In addition, he must have shown the effects of changing environmental conditions on the adaptations made by human species due to those changes.

Fill in the blank below with the vocabulary word that best completes the sentence. ___is the science of naming and classifying organisms based on structural comparisons and genetic evidence

Answers

TAXONOMY is the science of naming and classifying organisms based on structural comparisons and genetic evidence.

Taxonomy is the field of study aimed at naming, describing and classifying all forms of life.

Characters used for descriptive purposes are called taxonomic characters. A character can be defined as any phenotypic trait of an organism, which can be measured and/or weighed.

Molecular taxonomy uses the genetic information contained in the DNA molecule to establish relationships between species.

In conclusion, TAXONOMY is the field of study used to name and classify organisms based on structural comparisons and genetic evidence.

Which of the following describes natural selection? A. A population of mammals lives near the water, water levels rise and the habitat becomes swampy, the animals have trouble moving in the water, the population changes to a shorter-legged type so they can move more easily in the water B. A population of mammals lives near the water, water levels rise and the habitat becomes swampy, the act of swimming shortens the legs of the mammals, the offspring of the mammals have shorter legs C. Water levels rise and a habitat becomes swampy, a population on high ground observes the change, individuals with shorter legs migrate to the area D. A population of mammals varies in the length of their legs, water levels rise and the habitat becomes swampy, the individuals with shorter legs are better able to swim to food, the population evolves to become shorter-legged 1 points

Answers

the answer is D. it shows how the population changed because the shorter legged animals survived and continued the population while the long legged animals died away.

Final answer:

Natural selection occurs when there is variation within a species, inheritance of the variations, and a limit on resources. This leads to individuals with advantageous traits having a higher chance of survival and reproduction. The best example given was a population of mammals that evolved to have shorter legs due to a change in their habitat.

Explanation:

Natural selection is a crucial mechanism of evolution and it occurs when three conditions are present: variation within a species, inheritance of those variations, and a population limitation on resources consumed. This leads to a survival competition, where advantageous traits increase an individual's chances of survival and reproduction, thus passing these traits onto the offspring.

In the given options, the description that fits most closely with natural selection is: 'D. A population of mammals varies in the length of their legs, water levels rise and the habitat becomes swampy, the individuals with shorter legs are better able to swim to food, the population evolves to become shorter-legged'. This example demonstrates genetic variation (the different leg lengths), selection pressure (the change in habitat), and selection advantage (shorter legs being more suitable for the new conditions).

Explain how humans add carbon dioxide to the atmosphere and how they can reduce the amount of carbon dioxide in the atmosphere

Answers

Humans add carbon to the atmosphere in many ways. For example:
- Car emissions
- Factories
- Electric powerplants
- Fires
- Etc.

We as humans can reduce our carbon footprint by using more efficient ways of powering our lives by:
- Using renewable energy sources
- Turning off devices when not in use
- Not keeping cars on idle
- Etc.

Answer:

If you drive your car less and don't carpool, you will reduce the amount of carbon dioxide in the atmosphere. Another thing is to stop the factories from producing as much carbon dioxide released into the atmosphere.

Hope this helps.
