Widder can identify different species by observing the differences in:
ColorShapeSizeAmong others.What is a specie?The word specie is used in biology to refer to a group of organisms that can reproduce consistently as they share the same taxonomy.
How can Widder identify different species?Identifying species is possible through multiple techniques that include:
Analyzing the genes of the organism.Identifying species based on observation.In the case of observation, which is a common technique. The best is to observe the physical characteristics of the organism that can make it different from other species. This includes observing:
Shape ColorSizeBehaviorAmong others.Note: This question is incomplete because there is no information about the species Widder is observing. Due to this, I answered it based on general knowledge.

Answer: Edith Widder uses the bioluminescence (light) produced by the different sea creatures to identify their various species. For example, during her talk, she mentions a fish with a headlight behind its eye that retracted like a Lamborghini’s headlight. She also describes a Christmas tree fish where everything lights up, including the jewel-like organs in its body.
Explanation: This question comes from the TED talk "Glowing life in an underwater world" by Edith Widder. During her talk, she vividly describes her experience seeing sea organisms that display bioluminescence in the ocean.
Alligator
A- Producer Primary Consumer
B-Secondary Consumer
C-Tertiary Consumer
D-Decomposer
Answer:
C-Tertiary Consumer
Explanation:
The diets of tertiary consumers may include animals from both the primary and secondary trophic levels. Like secondary consumers, their diet may also include some plants. Examples of tertiary consumers include Hawks, Alligators and Coyotes. Hawks feed on small mammals, lizards and snakes.
Many freshwater plants have adapted to low carbon and light levels by adapting what feature?
Group of answer choices
Carnivorous plants
No need for carbon dioxide
Camouflage
Floating leaves
Answer:
The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floating leaves and finely dissected leaves are also common. Aquatic plants can only grow in water or in soil that is frequently saturated with water. They are therefore a common component of wetlands.
How does low turgor pressure affect a plant?
Plant cells have some organelles that animal cells do not. Check all organelles that ONLY plant cells have.

nucleus
C
cell membrane
D

F
mitochondria
Answer: Plant cells only have chloroplast and a cell wall. Which is A and E.
How could an asteroid impact have led to the extinction of dinosaurs?
Answer:
The asteroid crashed into the earth and made some water bodies violent
it is said that the asteroid was super huge and was capable of causing volcanoes, tsunamis, etc which took place all over the earth and extincted dinosours. But it is a little surprising that crocodiles who were also found at that time survived all this
Answer:
Probably the asteroid caused natural calamities
In the experimental set up above there are bubbles being
produced. What gas would be inside the bubbles?
Answer:
carbon dioxide
Explanation:
The two birds shown in Figure A and B are found on one island. The bird species in figure A is moved to a new island, where food size and shape are different from the food found in their current island. The birds left behind (Figure B) on the original island continue to grow and reproduce.
What changes might a scientist expect to see in the species?
A.
The birds on the old island would not change over time and evolve.
B.
The birds on the new island would evolve over time and die out.
C.
The birds on the old island would evolve over time and develop adaptations in their beaks to allow them to eat new types of food.
D.
The birds on the new island would evolve over time and develop adaptations in their beaks to allow them to eat new types of food.
Answer:
D.
Explanation:
because if the birds in figure A move to the new island with new food size and shape they will adapt to the food
Which of the following statements are true regarding cellular reproduction? Select all that apply.
When an organism grows, cellular reproduction creates new cells.
Organisms reproduce, so new cells are needed.
If cells become damaged, cellular reproduction can repair damaged cells.
Cellular reproduction helps organisms acquire water better, as there are more cells present.
Cellular reproduction is the exchange of homologous chromosome segments.
Answer: Replacing dead cells

Which best describes the relationship between population size carrying capacity and limiting factors
Does the distance from earth to sun determine the seasons? please explain
Answer:
nope
Explanation:
Contrary to popular belief, the seasons are not determined by the earth's distance from the sun. The seasons are actually caused by the earth's tilted axis. Because the axis is tilted, when the Northern Hemisphere is tilted towards the sun, it's warm.

True or False: Competition occurs between plants that use the
same resources.
Answer:
True
Explanation:
What type of evolutionary mechanism did this story show?
Allele frequencies in a population may change due to four fundamental forces of evolution: Natural Selection, Genetic Drift, Mutations and Gene Flow. Mutations are the ultimate source of new alleles in a gene pool. Two of the most relevant mechanisms of evolutionary change are: Natural Selection and Genetic Drift.
This story showed an example of convergent evolution. Convergent evolution is the process whereby organisms that are not closely related independently evolve similar traits as a result of having to adapt to similar environments or ecological niches.
What is in the story ?In this story, the two species of birds, the crows and the jays, evolved to look similar as a result of living in the same environment and competing for the same resources.
The two species evolved to look similar in order to blend in with their environment, making it difficult for predators to distinguish them from one another. This allowed them to survive and thrive in the same environment.
Therefore, This example of convergent evolution is a perfect example of how species can evolve to look similar in order to survive in the same environment. It also shows how competition for resources can drive species to evolve similar traits in order to survive.

At which latitudes do we find Earth's major deserts?
Answer: Around 30-50 degrees of latitude. This is roughly right above and below the equator.
Explain the difference between homology and analogy using a wolf, a whale, and a shark:
Answer:
Explanation:
Analogy refers to traits or structures like body shapes, fins which evolved independently that are similar in organisms that are not related by the same common ancestor. For example dolphins and shark have similar body structures like fins but they are unrelated. Whale and shark too. Whales are mammals, sharks are fish.
Homology refers to traits or structures
posses by organisms that are related by common ancestors. Example wolf and whales.....they are both mammals.

Is Earth always the same distance from the
Sun? Explain.
Answer:
No

The earth travels in an ellipse, an ellipse is a flattened circle, and the sun is closer to one end of that ellipse and far in another end. That said the Earth is not the same distance as the sun
Phillip Gingrich finds an S-shaped bone in this partial skull, a sigmoid process, which is unique to
one particular order of animals in the water today... which one?
Answer:
A primitive whale which he named Pakicetus.
Explanation:
Philip Gingrich is a vertebrate paleontologist at the University of Michigan. He has performed extensive research on whales at the Egyptian desert of Wadi Hitan. His research team member discovered a skull whose braincase was bigger than that of a walnut. Gingerich was able to link the small-brained animal, to an early whale.
The auditory bulla had an s-shaped bony crest known as the sigmoid process and these two features helped whales to hear in water. The case, however lacked other features that helped whales hear beneath the waves. This led Gingrich to the conclusion that the unknown animal was semi-aquatic. This finding also lent credence to the possibility of whales evolving from terrestrial animals.
A cell that is placed in distilled (plain) water will swell up because it fills
with water. Which process causes the cell to swell?
Answer:
If a cell is placed in a hypotonic solution, water will move into the cell. This causes the cell to swell, and it may even burst. A hypertonic solution means the environment outside of the cell has more dissolved material than inside of the cell. If a cell is placed in a hypertonic solution, water will leave the cell.
