During A Storm, Several Butterfly Eating During A Birds Were Blown To A Distant Island. The Island, Which

Answers

Answer 1
The answer is D. A genetic mutation led to punctuated equilibrium
Answer 2

The most likely reason for the change in the butterfly population to darker colors is natural selection due to bird predation. Dark-colored butterflies had a survival advantage and became more common over time.

The most likely explanation for the change in the butterfly population is natural selection. When birds introduced to the island began preying on butterflies, those with darker colors, such as dark green and brown, had a survival advantage because they were better camouflaged against predators. Over time, this led to an increase in the population of darker-colored butterflies, similar to how the peppered moths in England changed color due to soot from the Industrial Revolution.

Steps of Natural Selection:

Variation: Initially, the butterfly population had a range of colors.Selective Pressure: The introduction of bird predators created a new threat.Survival Advantage: Darker butterflies were less visible to predators and more likely to survive and reproduce.Shift in Population: Over generations, darker butterflies became more common as they were selectively favored.

This scenario illustrates how environmental pressures can lead to changes in the traits of a population over time through the process of natural selection.

Answers

''If oxygen is NOT present, glycolysis is followed by fermentation.''
Final answer:

In the absence of oxygen, the process that follows glycolysis is fermentation. It is an anaerobic process with two types: lactic acid fermentation and alcoholic fermentation.

Explanation:

If oxygen is not present, the process that follows glycolysis is known as fermentation. Fermentation is an anaerobic process, which means it occurs in the absence of oxygen. Fermentation allows glycolysis to continue by producing the NAD+ needed for this pathway. There are two types of fermentation: lactic acid fermentation and alcoholic fermentation. Muscle cells in the human body, when lacking sufficient oxygen during exercise, will perform lactic acid fermentation while yeast cells perform alcoholic fermentation.

Which of the following is critical in developing a science question?

Answers

Developing a science question requires prioritizing testability and reliance on observable phenomena, ensuring meaningful contributions to scientific inquiry and knowledge generation. The correct answer is C. Ensuring it is testable and based on observable phenomena.

In developing a science question, the critical aspect lies in its ability to contribute to scientific inquiry and understanding. It should not merely conform to popular trends or aim for complexity to impress.

Instead, the question should prioritize testability and reliance on observable phenomena.

Firstly, a scientifically rigorous question must be testable. This means that it should be possible to design experiments or gather data that can provide evidence to support or refute hypotheses related to the question.

Testability ensures that the question leads to empirical investigation, which is fundamental to the scientific method.

Without the ability to test a question, it remains speculative and cannot contribute meaningfully to scientific knowledge.

Moreover, a science question should be based on observable phenomena.

This means that it should be grounded in real-world observations or measurable phenomena that can be studied systematically. By focusing on observable phenomena, scientists can gather empirical evidence to support their hypotheses and conclusions.

Observable phenomena provide the basis for constructing scientific models and theories that accurately describe and predict natural phenomena.

Contrary to the options presented, aligning with current popular trends or emphasizing complexity and technical jargon may detract from the scientific validity of a question.

Popular trends may be fleeting and not necessarily grounded in scientific inquiry, while complexity for the sake of impressiveness may obscure the clarity and coherence of the question.

Additionally, inundating a question with technical terms can alienate audiences and obscure the underlying concepts.

In summary, the critical aspect in developing a science question is ensuring it is testable and based on observable phenomena. This ensures that the question contributes meaningfully to scientific inquiry and facilitates the generation of reliable knowledge.

The correct answer is C. Ensuring it is testable and based on observable phenomena.

Complete Question

Which of the following is critical in developing a science question?

a) Ensuring it aligns with current popular trends

b) Making sure it is overly complex to impress others

c) Ensuring it is testable and based on observable phenomena

Which geographic features are associated with a divergent boundary?

Answers

In plate tectonics, a divergent boundary or divergent plate boundary as known  a constructive boundary or an extensional boundary is a linear feature that exists between two tectonic plates that are moving away from each other. 

Answer:

Tectonic plates.

Explanation:

At the divergent boundaries, two plates move away from each other and the space produced by this spacing is filled by a new magmatic crust material. Thus, the divergent limit is constructive, since it allows the expansion of the ocean floor and the consequent formation of a new lithosphere.

According to this concept, we can say that the geographical features that are associated with a divergent boundary are the tectonic plates.

Answers

This thing does back to their pedigree which mostly comes from their parents so one of the parents has a bent thumb and the other has a straight thumb

Answer: Due to different alleles.

Explanation:

Every trait is encoded by a particular gene and each gene has various alternative forms. These alternative forms of a given gene are known as alleles.The alleles that encode the shape of the thumb are of two types - one is the S allele which encodes a straight thumb and is dominant in nature whereas the second allele is the h allele which encodes for the bent thumb and is recessive in nature.Thus, the two children have different thumbs as they have received different alleles from their parents.

During photosynthesis, chloroplasts capture energy from the sunlight and use it to produce food in plant cells.

What is photosynthesis?

It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy  through the process of cellular respiration.

Some of the energy which is converted  is stored in molecules of carbohydrates like sugar and starches  which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis  are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.

which of the following might show evidence of a year with low rainfall

Answers

Final answer:

Evidence of low rainfall in a specific year can be identified through decreased agricultural outputs, thin tree rings indicating stressful growing conditions, and historical climate events associated with dry conditions such as the Little Ice Age.

Explanation:

Evidence of a year with low rainfall can be seen in several aspects of our environment. Some of the clearest indicators may be observed in agricultural output, tree ring records and historical climate events.

First, significant droughts can impact agricultural production sharply. For instance, in 2014, the Manchuria Plain in China experienced its intense drought in 50 years, resulting in a dramatic decrease in wheat, corn, and soybeans supplies. Thus, in years with low rainfall, we may expect to see a decline in the amount of agricultural products supplied at any given price.

Secondly, nature provides its own historical record through annual tree rings. These rings can reveal prevailing climatic conditions during each growing season. A thin ring usually suggests low rainfall or high temperature stress which impaired growth.

Lastly, major historical climate events, like the Little Ice Age in Europe in the fourteenth century is characterized by cold weather and, in some areas, droughts which reduced available food supplies due to low rainfall.

A plant dying after being exposed to poison represents a physical change true or false???

Answers

Final answer:

The statement is false because a plant dying from exposure to poison is an example of a chemical change, as it involves a change in the plant's chemical composition, not just a physical alteration.

Explanation:

The question: A plant dying after being exposed to poison represents a physical change, true or false?. False. This statement is false because a plant dying from poison represents a chemical change, not a physical one. This is due to the alteration of the chemical structure within the plant as a result of the poison, which causes damage or death to the plant. For instance, when a toxic agent like poison interacts with a plant's biological systems, it can lead to a series of biochemical reactions that ultimately cause the plant cells to die, a process that involves a change in the chemical composition of the plant.

Additionally, the terms chlorotic (yellowing of leaves due to lack of chlorophyll) and necrotic (dead tissue) refer to conditions that are symptomatic of underlying chemical changes within the plant tissues. Therefore, exposure to poison and the resulting damage is a clear example of a chemical change.

If you were to examine the profile of a typical stream, you would probably find that the gradient is _____.

Answers

It's steepest near the head

If you were to examine the profile of a typical stream, you would probably find that the gradient is steeper at the headwaters (the upper part of the stream).

What is the gradient of a stream?

The gradient of a stream refers to the rate at which the stream bed slopes or descends over a given distance, usually measured in feet per mile or meters per kilometer. It represents the change in elevation of the stream over a horizontal distance and is an important factor that influences the flow and behavior of the stream.

If you were to examine the profile of a typical stream, you would probably find that the gradient is steeper at the headwaters (upper part of the stream) and gradually decreases as the stream approaches its mouth (lower part of the stream).

This is because the water at the headwaters has a higher potential energy due to gravity and is able to flow more quickly downhill, while the water at the mouth has a lower potential energy and flows more slowly.

Answers

Answer:

The cell can be identify by looking at their shape.

Explanation:

Plant cells have cell walls outside the cell membrane. Animals cells doesn't have any cell wall.

The shape of plant cells are generally square or rectangle. The slide contains cells with square shape cells, that means the cells are plant cells. If the slide has oval or round shape cells , the cells are animal cells. Large vacuoles are visible only under the slides of plant cells.

Thus, the difference on the basis of cell shape and vacuoles can be used to identify plant and animal cells.

Cells are the living entities, which are the structural, basic, and functional units of all living beings. The eukaryotic cell can be divided into plant cells and animal cells.

The difference between the plant cell and animal cell are:

An animal cell is a eukaryotic cell, with membrane-bound organelles and an eccentric nucleus. The animal cell consists of the cell organelles centrosomes, lysosomes, ribosomes, Golgi apparatus, mitochondria, cytoplasm, and cell membrane.

The plant cell is a eukaryotic cell with an eccentric nucleus and comprising the organelles like cell walls, chloroplasts, vacuoles, and other membrane-bound organelles.
