When you mix red, blue, and green light equally you get white light, because in this case all these colours get added. But exact opposite happens in the case of paint. In paint, these colours gets subtracted to form black colour.
In simple words, when we mix paint, all the light falling on the paint gets absorbed. So, it reflects no light and gives black colour. This is because the light that doesn't get absorbed by one pigment gets absorbed by the other one. So, all the light gets absorbed.
How are sedimentary rocks made. A. Magma or lava is cooled B. Materials are pressed together C. Chemical reactions change minerals. D. Earthquakes causes small pieces to fall
Answer:
B. Materials are pressed together
Explanation:
sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock.
Sedimentary rocks are made up by the pressing down together the materials which are loosened through weathering. Thus, the correct option is B.
What are Sedimentary rocks?Sedimentary rocks are the type of rock which are formed by the accumulation or deposition of mineral particles or organic particles at the Earth's surface, followed by cementation of the particles.
Pieces of rock are loosened by weathering of particles, then these are transported to basin or depression where the sediment is trapped. If the sediment is buried deeply in the basin, it becomes compacted and cemented to form sedimentary rocks. Clastic sedimentary rocks may have particles of rocks ranging in size from microscopic clay to huge boulders.
Therefore, the correct option is B.

Why do earthquakes occur near the San Andreas fault?
A
One plate slowly pushes the other plate up.
B) A trench is created as one plate slides under the other plate.
Portions of the plates get stuck and then suddenly loosen and move.
D
One plate pushes hard enough to reverse the motion of the other plate.
Answer:
C.
Explanation:
Basically a faster explanation is the san andreas fault is a transform boundary. If you have an oreo break one of the top pieces and slide them slowly it will get stuck causing an earthquake.
Earthquakes occur near the San Andreas fault because portions of the plates get stuck and then suddenly loosen and move. Hence option C is correct.
What is earthquake?Earthquake is defined as the abrupt release of energy in the Earth's lithosphere that causes seismic waves and causes shaking of the planet's surface. Earthquakes typically result from subsurface rock breaking unexpectedly and rapid movement along a fault. The seismic waves that cause the ground to tremble are brought on by this quick release of energy.
According to new University of Southern California research that contributes to the understanding of how earthquakes occur, tremors along a notorious section of California's San Andreas Fault seem to be fueled by thermal instability brought on by frictional shear occurring much deeper in the Earth than previously thought.
Thus, earthquakes occur near the San Andreas fault because portions of the plates get stuck and then suddenly loosen and move. Hence option C is correct.

Our understanding of both biology and geology is based on the idea that living things and environments have changed
Group of answer choices.
A. Only since humans appeared.
B. Repeatedly, rapidly and rarely.
C. Slowly, over billions of years.
D. Very little since Earth began.
Answer:
C. Slowly, over billions of years.
Explanation:
Environmental science can be defined as an interdisciplinary field of science that comprises of chemistry, economics, engineering, zoology, geography, geology, biology, ecology, physics, etc., used for the study and understanding of various environmental factors, issues in relation to human life.
Our understanding of both biology and geology is based on the idea that living things and environments have changed slowly, over billions of years.
This understanding is made possible through the study of the relationship between living organisms and their environment, as well with other forms of life found in the ecosystem.
An ecosystem can be defined as the natural living habitats of both living and non-living organisms. Essential services such as plant pollination, water purification, nutrient cycling etc that are being provided by the ecosystem are really very vital, important and useful for the sustenance of life, both for humans and enhances social welfare.
Basically, scientist have been able to study the remains of various living organisms (fossils) from billions of years ago and discovered that the change between the living organisms and the environment occured slowly.
Overtime organisms change sometimes they change so much of the sentence may be completely different for their ancestors what must happen for this process to occur
Answer:
In order to survive in the changing environmental conditions.
Explanation:
Changes occur in the body of an organism which make them different from their ancestors because these organisms evolve with the passage of time due to difference in environmental conditions. If these organisms can't evolve, they can't tolerate that environment and climatic condition and also become extinct so this process occur in the organisms in order to survive that different environmental conditions so we can say that this change is necessary in the organisms to survive.

The cellular mechanism that determines the independent assortment of maternal and paternal chromosomes is: Please choose the correct answer from the following choices, and then select the submit answer button. determined by their dominant or recessive inheritance pattern. separation of sister chromatids at anaphase II of meiosis. separation of sister chromatids at anaphase I of meiosis. separation of homologous pairs at anaphase II of meiosis. separation of homologous pairs at anaphase I of meiosis.
Answer:
separation of homologous pairs at anaphase I of meiosis.
Explanation:
Independent assortment law establishes that the alleles from two or more different genes distribute in gametes independently from each other. In other words, a gamete receives an allele from a gene that does not depend or influence the allele of another gene in the same gamete. This random distribution can only be applied to independent genes. These genes segregate independently after crossing over because they are located far away from each other.
When cell division is going on by meiosis, it involves the random and independent segregation of the alleles. During anaphase I (meiosis), the pairs of homologous chromosomes separate independently of each other. Each integrant of the homologous pair migrates to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. The process is as follows.
During metaphase I, homologous pairs together migrate to the equatorial plane, where they randomly aline with their kinetochores facing opposite poles. The random arrangement of tetrads is different in every cell going through the meiosis process. There is no equal alinement between two cells. When tetrads aline in the equatorial plane, there is no predetermined order for each of the homologous chromosomes of each tetrad to face one of the poles and then migrate to it while separating. Any chromosome of the homologous pair might face any of the poles and then migrate to it. Each of the chromosomes has two possibilities for orientation at the plane. During anaphase I, each of the homologous chromosomes migrate to the corresponding pole. When the new haploid cells are formed, the number of variations in each cell is also different and depends on the chromosomes that form that cell. This random order in the equatorial plane is what introduces variation into the gametes. It is almost impossible that two gametes resulting from meiosis will get the same genetic charge.

2. What is the change (mutation) in DNA?
Answer:
A mutation is a change in a genetic sequence. Mutations include changes as small as the substitution of a single DNA building block, or nucleotide base, with another nucleotide base. Meanwhile, larger mutations can affect many genes on a chromosome. Along with substitutions, mutations can also be caused by insertions, deletions, or duplications of DNA sequences.
Explanation:
Some mutations are hereditary because they are passed down to an offspring from a parent carrying a mutation through the germ line, meaning through an egg or sperm cell carrying the mutation. There are also nonhereditary mutations that occur in cells outside of the germ line, which are called somatic mutations. Mutations can be introduced due to mistakes made during DNA replication or due to exposure to mutagens, which are chemical and environmental agents that can introduce mutations in the DNA sequence, such as ultraviolet light. Some mutations do not result in changes in the amino acid sequence of the encoded protein and can be described as silent mutations. Other mutations result in abnormal protein products. Mutations can introduce new alleles into a population of organisms and increase the population's genetic variation.

4. The peppered moth lives on the trunks of trees in England. There are two colorations of this moth, light and dark, and both
are eaten by birds. A study found that prior to the Industrial Revolution, the number of light-colored moths found on the
trunks of trees was far greater than the number of dark colored moths. However, after the industrial Revolution, the numbers
were reversed
How would the genetic variation of the moths account for the change in the population sizes of each color? 50.7L152
A. The dark moths were able to kill off many of the light-colored moths, so their numbers increased a lot.
B. Natural selection caused the light species of moth to change into the dark species, allowing them to be better
hidden
C. After the industrial Revolution started, the light colored moths left the area to go live in another, less populated
environment
D. Natural selection favored the dark-colored moths because the factories were producing soot that landed on the
trunks of the trees.
Answer:
D.
I remember doing a question like this in class while learning about natural selection. The 2 colorations of moth live in a habitat that originally supported the lighter variant due to the light-colored trees. When the industrial revolution began, the soot levels reversed this because the black moths were more camouflaged that the lighter ones. A way we could prove this was the amount of black dresses and dark colored clothing during the time, often due to the fact that lighter colored clothing would turn black by the time the wearer arrived home. The lighter colored moths simply died off a bit because of this.

Errors that occur during meiosis are present in all cells of the body, whereas errors that occur during mitosis may occur in only a small number of cells.
Answer:
Due to difference in their presence in the body.
Explanation:
Errors that occur during meiosis are present in all cells of the body because meiosis cell division occurs in the sex cells of an organisms so that the errors are effects all the cells of that organism, while on the other hand, errors that occur during mitosis may occur in only a small number of cells because mitosis cell division occurs in the somatic cells so the errors are present in some body cells so we can conclude this errors in meiosis affect all cells whereas errors in mitosis affect less number of cells.
