Answer:
the light coloured butterfly undergo gene mutation to develop a darker colour
Explanation:
As the time passed,the trunk of the tree due to air pollution and other factors turned dark so the light coloured butterflies were easy visible to predators.they underwent gene mutation and changed their colour so they can survive.

Explain how the process of weathering changes rock to eventually, over a long time, to become soil.
Answers
Answer:
Rocks turn into the soil through the process of weathering. Weathering is when rocks are broken down into smaller pieces. Over time a large rock is broken into smaller and smaller pieces, eventually turning into soil. Chemical weathering occurs when water gets inside of a rock and reacts with some of the mineral components of the rock, chemically changing them and weakening the rock's structure. This causes the rock as a whole to break down, and over time chemical weathering can break a rock into small enough pieces to become soil. Once the rock is in very tiny pieces, it mixes together with organic and other inorganic elements to form the soil we are familiar with.

Explanation:
Is there a connection between a star's size and a star magnitude?The brighter the star, the smaller the magnitude. So, no. There was no connection between the size and magnitude.
Name a different property other than the ones in the chart that can also be used to classify stars.Temperature, mass, color, luminosity, and size.
The magnitude of a star decreases with its brightness. So, no. The size & magnitude had nothing to do with one another.
What is star?All of us are reasonably familiar with stars. On the majority of clear nights, we can see them as minuscule, glittering specks of light throughout the sky. Numerous poems, stories, or nursery rhymes have been written about stars.
The star is supported against gravity by nuclear fusion events in its core, which also yield photons, heat, and trace amounts of metallic elements. The Sun comes the star that is closest to Earth. The magnitude of a star decreases with its brightness. So, no. The size & magnitude had nothing to do with one another. mass, colour, luminosity, size, and temperature. In addition to the ones that are in the chart, these are separate properties.
Therefore, the magnitude of a star decreases with its brightness. So, no. The size & magnitude had nothing to do with one another.

Organs that work together are grouped into organ systems. The organism level is the highest level of organization. An organism is a living being that has a cellular structure and that can independently perform all physiologic functions necessary for life.
The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems.
Life processes of the human body are maintained at several levels of structural organization. The six levels of the structural organization are Chemical, cellular, tissue, organ, system and organism.

explain the difference between dominant and recessive traits or alleles
recognize phenotype as the physical expression of the genotype
recognize genotype as the collective sum of all alleles and their specifying traits
analyze animals to demonstrate evidence of the hereditary information that is passed from one generation to another. Welcome to Hamster Haven!
We are the world's largest pet store and research facility dedicated to studying hamster heredity.
Inside we have a team of geneticists who oversee the breeding and offspring of the hamsters to ensure that we have many varieties for our customers to choose from.
Recently, our team of geneticists has been studying how hamsters inherit fur length.
You are invited to join our team to assist in the process.
Let's take a look at our geneticist notebook to learn more about how traits are inherited.Let's take a closer look at cells. Inside of each cell is a nucleus. The nucleus is like the command center for the cell and houses all of the cell's genetic material, called chromosomes. Tightly wrapped in the chromosomes are individual proteins, called genes, on strands of DNA.raits are determined by the genes the hamsters inherit.
Each hamster can inherit the trait for long fur or the trait for short fur.Let's examine the hamsters that you will be investigating today.
Select each hamster to learn more about its dominant and recessive traits.

In this lab you are studying about how a hamster inherit traits from their parents when you breed short fur and long fur female and male in various orders.
After completion of this experiment in the lab you will have the idea of how every organism requires a set of instructions that decides its traits.You will be able to identify the dominant and recessive traits of a hamster when different fur female and male are made to breed , and how the heredity is passed from one generation to another .Hence by getting the idea of all these things you will be able to breed different type of hamster , and that has helped the pet store to make different offspring with different characteristics for customers with different requirements.
