Answer: There are four principles at work in evolution—variation, inheritance, selection and time. These are considered the components of the evolutionary mechanism of natural selection. After a while the birds will get old and their beaks will get weaker, eventually they will die, when there is a shortage of food they will start harming each other in order for it, that’s selection.
Birds with short, hard beaks can eat nuts more efficiently than birds with long, pointy beaks.
The following would happen to a population of birds with short and hard beaks over time:
The rivalry( more birds than food)Birds with short beaks are more likely to survive.Birds with short beaks live longer lives and reproduce more.What is evolution?Evolution in biology is the change in a species' characteristics over several generations that is based on natural selection.
What is natural selection?Natural selection theory states that individuals who are less adapted to their environment are eliminated and those who are better adapted are selected by nature.
Principles of natural selection4 principles of natural selection are as follows:
Variation:
Individuals in all species differ in their genetic makeup, resulting in many variations in their physical features.Individuals within a population differ from one another.Inheritance:
Individuals pass on some of their genetic material to their children, and parents pass on their characteristics to their children.Selection:
Some people have inherited traits (genes) that enable them to live longer or have more children. These offspring are more likely to survive and have children of their own. As a result, their genes spread throughout the population; some variants reproduce more than others.Time:
The selection causes changes in species over time. These modifications may take days, decades, or millions of years to take effect; successful variations accumulate over time.Thus, we can conclude that the 4 principles of natural selection are variation, inheritance, selection, and time and birds with short and hard beaks will compete against each other and the most suitable will survive.

Describe the factors that influence an individuals phenotype
Answer:
Physiology, behavior and morphology are considered as phenotype of an individual as these attributes can be observed. Example of phenotypes include wing length, hair color, skin color and height.
There are basically two factors that influence the phenotype:
(1) Genotype or Genetic information of the individual: Some of the phenotypes such as height and skin color are transmitted genetically from generation to generation. Genetic information is the transfer of genes that carry some of the specific genetic information and pass it to another generation which is visible in their phenotype.
(2) Environmental influence: As the phenotype attributes are variable so they are highly influenced by the environment or surrounding they are living. Environmental condition such as temperature, diet, humidity, oxygen levels, and the presence of mutagens affects the phenotype of an individual.
Hence, Genotype and environmental factors influence an individuals phenotype.
What does a completely filled circle represent on a pedigree chart? Group of answer choices A female carrier of a disease A male carrier of a disease A female with a disease A male with a disease
Answer: A female with a disease.
Explanation:
A pedigree chart is a diagrammatic representation of the phenotypes that are associated with the members of the family and with their generations. These phenotypes can be responsible for the development of eye color, facial forms, skin color, a particular disease or disorder.
In a pedigree chart a dark circle or filled circle represent that the female is affected by the disease or disorder, whereas a white or unfilled circle represent a female is unaffected or disease free.
Answer:
A female with a disease.
Explanation:
The map shows the main streams and the rivers near City A and City B, as well as the nearby factories and farmland. The arrows in the diagram show the direction of the water flow. City A gets its water from the sunset River and City B gets its water from the Moth Lake. A liquid herbicide was applied to a farmland. Based on the information in the map shown, which city would most likely have the best water quality and why? Choose the best answer.
Select one:
City A because there are no pollution sources upstream.
City B because it is fed by two rivers instead of just one.
City B because it is next to a lake which would have more clean water available.
City A because it is farther North which means it is colder so the water is cleaner.
Answer:
A. City A because there are no pollution sources upstream.
Explanation:
Water pollution is th contamination of water. There are many means through which water is contaminated such as industrial waste, agricultural waste and domestic waste et-cetra.
City A and City B get water from sunset lake and moth lake which have factories (industrial waste) and farmland (agricultural waste) nearby them, which are responsible for the contamination of river water. due to this cities can recieve contaminated water which can affect their health.
But the quality of water in City A will be best than that of City B because according to the image, City A do not have nay upstream soooooource of pollution, as factories and farmland are located at downstream.
Hence, the correct option is A.

ANSWER
we understand ourselves and our motivations. we may not u sweat and others and their motivations as easily.
hope this helps :)
Answer:
Responses may vary but should include some or all of the following information:
The actor-observer bias is a form of attribution bias in which a person is more likely to make an external attribution for behavior when acting and more likely to make an internal attribution for behavior when observing another. The actor-observer bias likely occurs because individuals are more likely to understand the constraints under which they act but are less likely to understand what constrains others.

List three environmental benefits of golf courses?
Answer: They provide a wildlife habitat, also protect topsoil from water and wind erosion, and third, they improves air quality
Explanation:
Final answer:
The environmental benefits of golf courses include preservation of biodiversity, carbon sequestration, and water management.
Explanation:
1. Preservation of biodiversity: Golf courses can provide habitats for various wildlife species, including birds, insects, and small mammals. These habitats can contribute to the preservation of biodiversity in the surrounding areas.
2. Carbon sequestration: Golf courses with their well-maintained grass and trees can absorb carbon dioxide from the atmosphere through the process of photosynthesis. This helps in reducing the greenhouse gas emissions and mitigating climate change.
3. Water management: Many golf courses implement efficient irrigation systems and water conservation practices. This reduces the demand for fresh water and helps in the preservation of water resources.

The green color of the caterpillar is an example of a
itself from the insect's attack is a
adaptation
adaptation to avoid predators, while the release of bioactive chemicals by the plant to protect
The green color of a caterpillar often functions as a part of aposematic coloration— a biological adaptation warning predators of toxicity or distastefulness. Examples include the monarch butterfly caterpillar's bright colors and fire-bellied toads' red or orange bellies, both of which serve to deter predators using visual cues.
The green color of the caterpillar is an example of aposematic coloration, which is a type of adaptation used by some species to warn predators of their distastefulness or poisonous nature. This warning coloration involves bright and conspicuous colors that advertise to potential predators the unsuitability of the organism as prey. For instance, the monarch butterfly caterpillar sequesters poisons from its diet of plants and milkweeds, making it poisonous or distasteful. This is visually communicated through its bright yellow and black coloration, which serves as a deterrent to predators.
Similarly, fire-bellied toads have toxins that make them distasteful, and they display bright red or orange colors on their bellies to discourage predators from attacking. This strategy is effective only if the predator uses vision to locate prey and can learn from the negative experience of eating the poisonous or distasteful organism.

am was sitting at his desk in front of a window doing his homework. Sunlight shined through the window and a glass of water on the desk and created a rainbow across Sam's paper. Where did the colors in the rainbow come from?
Since the glass was curved, it made the sunlight change colors.
The white sunlight was separated into all the colors that make up white light.
The only way the rainbow could appear is because of a picture on the glass.
Answer:
The white sunlight was separated into all the colors that make up white light.
Explanation:
The sunlight shines into the water droplets in the air, bending as it moves from the air into the water, reflecting off the sides the drops, and bending again as it exits the drops. As a result, all of the colors in the white light of the sun separate into the individual bands of color characteristic of a rainbow.

Believe me , biology is another thing.
Consider two ecosystems that scientists have labelled as ecosystem A and ecosystem B. The scientists have found that both ecosystems are
home to a roughly equal number of species. However, ecosystem A is dominated by a small number of species that are very abundant.
Ecosystem B, by contrast, has a more even abundance of organisms across Its species.
From this description, ecosystem B is considered
ecosystem A.
A.
less biodiverse than
B.
equally biodiverse as
C. more biodiverse than
D. more valuable than
Ecosystem B is more biodiverse than Ecosystem A due to the more even abundance of different species in it, indicating a higher level of biodiversity.
Explanation:From the descriptions, we can infer that Ecosystem B is more biodiverse than Ecosystem A. This is because, in ecosystem A, there is an apparent dominance of a small number of species, while ecosystem B shows a more even abundance of organisms across its species, which signifies a higher level of biodiversity. Biodiversity is a measure of the variety of organisms present in different ecosystems. This can refer to genetic variation, species variation, or ecological variation within an area, biome, or planet. Greater biodiversity implies greater health for the ecosystem.
