Describe how an organism is classified currently hy Biologist
Answers
Answer: All living organisms are classified into groups based on very basic, shared characteristics. Organisms within each group are then further divided into smaller groups. The classification of living things includes 7 levels: kingdom, phylum, classes, order, families, genus, and species.
Explanation:
Answer:
Organisms are classified by how similar they are to another organism.
They also find similarities with the DNA and examining physical features.
Explanation:
Modern biologists use DNA for this. Testing an organisms DNA can greatly help in classifying organisms.

primary
Explanation:
Primary succession occurs when new land is formed or bare rock is exposed, providing a habitat that can be colonized for the first time. For example, primary succession may take place following the eruption of volcanoes, such as those on the Big Island of Hawaii. As lava flows into the ocean, new rock is formed.

What is the difference between Original Remains, and Trace Fossils? Give 3 examples of each
Answers
Answer:
Please find the difference below and their respective examples
Explanation:
Previously existing organisms leave behind evidences of their existence in form of remains that has been collected and mineralized called FOSSILS. However, the fossils of an organism (plant or animal) can either be a trace fossil or an original remain/body fossil. The difference between the two are as follows:
- An original remain is the fossilized body or body part of an organism that once existed. For example, bones, shells and fossilized leaf are examples of original remains.
- On the other hand, trace fossils refers to any form of evidence, apart from the organism's body, that suggests the presence of that organism in that particular place at a particular time. Trace fossils are said to be illustrate presence of life but indirectly (via their activities). Examples of trace fossils are burrows, tracks, marks etc.

Do you believe that environmental factors have shaped human characteristics. If so in what ways?
Answers
Answer:
Yes
Explanation:
Environmental factors caused many different traits in people, for instance the different skin pigments of people depend on where their ancestors came from. European descendents tend to absorb more sunlight and get sunburned easily, whereas African descendents have skin that is suitable for their environment. Other characteristics include immunity to malaria or the speed at which one's blood can carry oxygen. These traits came slowly through natural selection as people evolved to become suited for their environment.

Sara is watching television when the power goes out. When she walks to the kitchen to get a candle, she knocks over a chair. She lights a match and holds it to the wick of the candle. She uses the light from the candle to find her way to the chair, which she picks up and sits in. Which of the events was a chemical change? *
Answers
Answer:
She lights a match and holds it to the wick of the candle.
Explanation:
Chemical change produces the required products of reactants by an irreversible reaction. For there to be a chemical change, a chemical reaction between reactants must occur.
Lighting of a match is a chemical change in which the friction between the match box and the gun powder on the stick produces a flame. This reaction produces a product by an irreversible process. After the flame burns out the wick of the candle, it can not be reversed.

Which reactant of photosynthesis is also involved in climate change?
A oxygen
B carbon dioxide
C water
D sugar
Answers
Answer:
B. Carbon dioxide
Explanation:
First of all, let’s write out the photosynthesis equation to identify the products and reactants.
6CO2 + 6H2O + energy —> C6H12O6 + 6H2O
In a chemical equation with the arrow pointing right, the reactants are on the left and the products on the right.
In photosynthesis, the reactants, carbon dioxide, water, and energy, react to form the products of glucose (sugar) and oxygen.
Now, let’s look at the answer choices. We can automatically eliminate choices A (oxygen) and D (sugar) because they are products.
We are left with B (carbon dioxide) and C (water). Water isn’t really considered a major contributor to climate change. Carbon dioxide is a greenhouse gas that traps heat in the atmosphere, causing climate change.
Therefore, the best answer choice is B. Carbon dioxide

Explain the similarities between prokaryotic and eukaryotic cells. Explain the difference between prokaryotic and eukaryotic cells.
Answers
Answer:
Prokaryotes do not contain membrane-bound organelles or genetic information within nuclei, while eukaryotes contain membrane-bound organelles and do store their DNA in nuclei. Both types of organisms may be producers and consumers
Explanation:
Cells are the basic microscopic elements of all organisms. There are two cell types: Prokaryotes and Eukaryotes.
Prokaryotic describes single-celled microorganisms that do not have a cell nucleus or other organelles surrounded by membranes. Eukaryotes are either single-celled or form complex multicellular bodies. They contain many membrane bound organelles, and their genetic information is stored within a nucleus.
Both groups may contain structures like cell walls, and carry out heterotrophic or autotrophic nutrition.
