The finch population's beaks will be modified; on dry islands, they will have larger beaks, while on rainy islands, they will prefer medium or short beaks.
What is natural selection?Natural selection is an evolutionary mechanism. Organisms that are better adapted to their surroundings are more likely to survive and pass on the genes that helped them thrive. Species change and diverge as a result of this process.
Because of the differences in environmental conditions, the finch populations on the dry and wet islands are likely to change differently over time.
Finches with traits that allow them to efficiently extract nutrients from dry seeds would have an advantage on the dry island, where food and water resources are limited.
Natural selection would favour these traits over time, increasing the frequency of these advantageous traits within the dry island finch population.
Thus, this way, the finch populations on these islands change over time.

The production plan for seasonal products is developed from a charted
______ that tracks the best plants to sell at different times of the year.
The production plan for seasonal products is developed from a charted "product demand cycle" that tracks the best plants to sell at different times of the year.
This cycle takes into account the natural growth cycles of different plants, as well as consumer demand for those plants during certain seasons. By following the seasonal cycle, growers can ensure that they are producing the right plants at the right time, maximizing their profits and reducing waste. This approach also helps ensure a steady supply of fresh, high-quality products throughout the year, which is important for maintaining customer satisfaction and building a loyal customer base.
A product demand cycle is a chart that shows the expected demand for a product over the course of the year. The cycle helps businesses to plan their production schedule to ensure that they have enough supply to meet demand during peak seasons. For example, businesses can use the demand cycle to determine when to plant certain types of flowers or plants so that they will be ready for sale during peak seasons.
Overall, the product demand cycle is a crucial tool for businesses to plan their production schedule, manage their inventory levels, and maximize their sales during peak seasons.

Darwin believed that the species with the best variation to their environment had the biggest chance at surviving.
What is Natural selection?
The process by which species adjust to their habitats is known as natural selection. It is the force behind evolution.
The process through which populations of living things adapt and change is known as natural selection. A population's members are naturally varied, which means that they are all distinctive in some ways.
This variety indicates that some people have characteristics that are more environment-appropriate than others. People that possess advantageous qualities, or adapted traits, are more likely to live and procreate.
Therefore, Darwin believed that the species with the best variation to their environment had the biggest chance at surviving.

Explanation:
The term eutrophication refers to the enrichment of surface water with nutrients. This process is related to human pollution activities.
Eutrophication is the biological process that generates in water by an oversupply of nutrients or organic matter. This matter, mainly compounded with nitrogen or phosphorous, favors the phytoplankton multiplication (microscopic plants growing on the water surface) and other aquatic plants. This overgrowth leads to an enhance in primary productivity. Nitrogenated compounds might come from human and animal wastes, while phosphorated compounds might come from fertilizers and other chemicals used in agriculture, that penetrates the soil and reaches water bodies.
Little by little begin sedimentation is caused by the death of some vegetable organisms that sink in the bottom. These sediments rich in organic matter suffer decomposition in the presence of oxygen.
When oxygen disappears, anaerobic bacteria act and produce fermentation.
On the surface, plants and phytoplankton keep growing, creating a mantle that impedes the light reach deeper areas. The phytoplankton overgrowth on the water surface and the fermentation processes in the bottom originate toxic compounds that damage the animals. Animals die, creating more sediments in the bottom where there are anaerobic conditions.
Decomposition and fermentation processes increase, producing a bad smell.
The result of eutrophication is the stratification of the water mass:
• First superficial layer, the overgrowth of blue-green algae, produces toxins and interrupts the pass of light to deeper areas. The surface then becomes warmer.
• The second layer might have oxygen available for the animals.
• In the third layer, there is no oxygen, so life is impossible for animals or plants.
• In the fourth layer, there are animals and plant remains in the process of sedimentation.
• At the bottom, there are organic matter and anaerobic bacteria in charge of decomposition and fermentation, through which they produce toxic gases and smell.

The layer of the atmosphere with the highest temperature is the blank
Answer:
The Thermosphere.......
The layer of the atmosphere with the highest temperature is the thermosphere.
What is thermosphere?The thermosphere is the outermost layer of the Earth's atmosphere, and it is located above the mesosphere and below the exosphere. This layer is characterized by extremely high temperatures, which can reach up to 2,500°C (4,532°F) due to the absorption of solar radiation.
Despite these high temperatures, the thermosphere is not actually hot in the sense that we normally think of temperature, as the air density is extremely low and there is very little heat transfer to objects within it.
The thermosphere is also the layer of the atmosphere where phenomena such as auroras and meteors occur, as well as where many satellites orbit the Earth.
It is an important part of the Earth's atmosphere, as it helps to protect the planet from harmful solar radiation and provides a habitat for certain types of high-altitude organisms.

the price of a book is thrice that of an exercise book. of a student spend #9600 on book and #8000 on exercise book, he has 56 items altogether:
(a) what is the price of an exercise book?
(b) what is the difference between the price of a book and an exercise book?
Answer:
a) price of an exercise book = #200
b) #400
Explanation:
Let x represent the price of the book
Let y represent the price of the exercise book
- According to this question, the price of the book is thrice that of an exercise book i.e. x = 3y
- Also, the question states that if a student spend #9600 on book and #8000 on exercise book, he has 56 items altogether. This means that to get how many books and exercise books he bought, we divide the price of book and exercise book he bought by the price of each book (x) and exercise book (y) respectively. Mathematically, this means:
- Student bought 9600/x books
- Student bought 8000/y exercise books
So, 9600/x books + 8000/y exercise books = 56 item
9600/x + 8000/y = 56
Since x = 3y
We can say;
9600/3y + 8000/y = 56
Find the L.C.M of 3y and y = 3y and solve using fraction method (see attachment).
9600 + 24000/3y = 56
33600/3y = 56
Cross multiply
33600 = 56 × 3y
33600 = 168y
Divide both sides by 168
33600/168 = 168y/168
200 = y
y = 200
Since, x = 3y
x = 3 × 200
x = 600
Therefore, the price of book (x) and exercise book (y) are #600 and #200 respectively.
b) The difference between the price of a book and an exercise book i.e. x - y
= #600 - #200
= #400
Help! • What do you already know about genetics mutations? • What do you wonder about Genetics Mutations?
Answer: A mutation is a change that occurs in sequence of the DNA.
Explanation:
Mutation is capable of manipulating the genetic information carried by the genes. A mutagen is any agent which brings about changes in the genetic make up of an organism. Those mutations which occur at the somatic cells are called somatic mutations but those that occur at the germline cells are called as genetic mutations. The genetic mutations are heritable that means they are passed on from parents to their progenies.
The genetic mutations are important as they bring about evolution of new traits in the generation of a particular species or in the generation of a particular individual. For example, genetic disorders and diseases caused by the genetic mutations are passed on to the next generation like cystic fibrosis, phenylketonuria, color blindness, and others. Thus identification of a particular genetic mutation is important to determine the cause of genetic diseases and disorders.

1. Describe two pieces of evidence that whales have evolved from land mammals
Explanation:
In addition to the vestigial leg bones and the series of transitional species in the fossil record, there is physiological and genetic evidence.
The physiological evidence is that whales swim with a modified running motion. If they had been specially created in the sea, there is no reason to have this holdover from life on land to let them swim.
Evidence for a horizontal fluke comes from the muscle attachments to move that fluke. Muscles pull on bone when they contract. Therefore bones have little bumps (sometimes not so little) on them as they add bone to handle the mechanical force of the contractions. Flukes can be inferred by the placement and size of the bumps on the vertebrae where the muscles that move the fluke (tail) are attached. Flukes themselves are soft tissue, and thus do not preserve well. But the bumps on the bone show a clear preference for muscle attachments on the top and bottom of the vertebrae, and these bumps get larger as the muscles evolve to be larger to move the fluke. If there is any other explanation and another inference, creationists have not provided it.
There is also the position of the nostrils over the course of evolution.

Although longitudinal waves can travel through all media types, what is the disadvantage of this type of wave transmission? Particles become too close together as they bump into each other making it more likely to hit other particles down the line. The waves travel in all directions which does not ensure that it will come into contact with particles down the line. The efficiency of the wave transmission is greatly diminished as the media becomes less dense. The oscillation of one set of particles has a huge impact on neighboring particles.
Answer:
The efficiency of the wave transmission is greatly diminished as the media becomes less dense.

a prey population consists of individuals with a variety of running speeds. The adaption that allows some of these animals to run fast would be an example of natural selection if it helps them
Answer:
Yes.
Explanation:
Yes, the adaption that allows some of these animals to run fast will be cause of natural selection because this fast running helps them to survive and save itself from predators. The organisms adapt certain features and characteristics in order to survive in that harsh environment that leads to natural selection. Natural selection occurs by selecting the best suited organism that can survive in that specific environment so this fast speed allows the organism to survive in their environment.
