6. (a) What two major changes have occurred in the North Fork Toutle River?
A massive landslide Mud flows in the Toutle river.
How changes have occurred in the North Fork Toutle River?There had been many earthquakes in the area prior to eruption but this happen to be a massive land slide because a moving magma have over steepened the mountain slopes.
This geologic process uses gravity to cause rock, soil, artificial fill or a combination of the three to move down a slope. Slow weathering of rocks as well as soil eruption and volcanic activity also causes landslides
Thus, massive landslide Mud flows in the Toutle river.

Explain how cancer cells grow.
Answer:
Gene mutations in cancer cells interfere with the normal activity within a cell.This can cause it to grow out of control and/or not die when it should. Cancerous cells can continue to grow because they behave differently than normal cells do. Cancer cells differ from regular cells in many ways,one of their more apparent traits is that they divide quickly with no control over them.The amino acid glutamine is one of the many key factors to helping the growth of cancer cells. Like all cells, cancer cells need nutrients to grow,sugar is one important fuel for it's development, but is far from the only factor.

DNA from a wolf is compared to DNA from a maple tree. Both will contain the
a. sugar deoxyribose and the base guanine
b. sugar deoxyribose and the base uracil
c. sugar ribose and the base guanine
d. sugar ribose and the base uracil
The DNA of both wolf and a maple tree contains the sugar deoxyribose and the base guanine.
What do you mean by DNA?DNA stands for deoxyribose nucleic acid. It is considered one of the most important genetic materials which are present in most organisms.
DNA possesses the sugar deoxyribose, while RNA contains the sugar ribose. As a wolf and a maple tree both possess genetic material DNA, the sugar found in both is deoxyribose.
DNA contains nitrogenous bases such as Adenine, Thymine, Guanine, and Cytosine, while RNA contains Uracil in place of thymine.
Therefore, the DNA of both wolf and a maple tree contains the sugar deoxyribose and the base guanine.

The Northern and Southern Hemispheres of Earth experience four seasons during the
year. What is the main reason for the change in seasons?
the rotation of the Earth on its axis
Answer:
Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.
This plant structure is responsible for producing leaves, transporting water and nutrients, and support the plant.
A) Roots
B) Seeds
C) Flowers
D) Stems
Answer:
D) Stems
Explanation:
Stems are a part of a plant that are responsible for various things. Their main responsibility is to support the plant, this is through holding up the leaves, flower, and buds. Stems also take nutrients and water from the roots in the ground and transport that up the stem and into the other parts of the plant. Lastly, leaves grow out of the stem, so it is responsible for that as well.

According to the research, birds are uniquely classified from other organisms because they all have feathers.
What are birds?It is an oviparous and vertebrate animal whose body is protected by plumage and which has a pair of wings generally suitable for flight.
Feathers are characteristics of the bird class thanks to these they can camouflage, regulate body temperature and identify and differentiate themselves from other groups of animals since they may have wings, beaks and legs, but none have feathers.
Therefore, we can conclude that according to the context, birds are uniquely classified from other organisms because they all have feathers.

Traits are passed from parents to offspring. These traits are determined by
(1) chromosomes, located on genes, found in the nucleus
(2) genes, located on chromosomes, found in the nucleus
(3) chromosomes, located on genes, found in the ribosomes
(4) genes, located on chromosomes, found in the ribosomes
Answer:
The traits that are transferred from the parents to the offspring during reproduction are determined by genes, located on chromosomes, found in the nucleus.
Explanation:
During reproduction, there is a fusion of;
male gamete
female gamete
This leads to the formation of offspring. There is a transfer of traits from the parents to the offspring.
Hence, the traits that are transferred from the parents to the offspring during reproduction are determined by genes, located on chromosomes, found in the nucleus.
Answer:
(2) genes, located on chromosomes, found in the nucleus
Explanation:
Traits are determined by genes which are located on chromosomes. Chromosomes, on the other hand, are located in the nucleus.
The chickenpox virus can remain latent in host cells by integrating its DNA into the host cell genome. This virus uses the ______ cycle as its main life cycle pathway.
The chickenpox virus can remain latent in host cells by integrating its DNA into the host cell genome. This virus uses the genoma replication cycle as its main life cycle pathway.
How does the virus replication process take place?Viral replication refers to the process by which a virus reproduces within a living organism. This usually involves turning infected cells into virus factories, which make copies of the virus's genetic code and expel them to spread into the host's body.
Upon replication, viruses produce new copies of themselves within infected cells.

Be specific about how invasive species impacts the environment here in Hawaii.
What will happen in the future if this issue is not addressed? Why does this issue need to be addressed?
Answer:
Terrestrially, invasive species are proving to be a major difficulty in Hawaii because the islands lack many natural predators of invasive animals. Invasive predators often move to the top of the food chain and disrupt prey populations, particularly small mammals, birds, insects, and plants. Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats. This can result in huge economic impacts and fundamental disruptions of coastal and Great Lakes ecosystems.

A. Point D
B. Point B
C. Point A
D. Point C
Answer:
Point B
Explanation:
Point B is getting the most light and is closet to the surface
Point B is getting the most light and is closet to the surface.
What is Photic zone?The daily cycle of light and dark in the photic zone of the world's oceans is maybe the most potent environmental signal accessible. Russell's suggestion that zooplankton resided in depths with the best light intensity was one of the early reports to propose that light had a major role in vertical migration.
He went on to say that as animals strayed from this zone of ideal light intensity, physiological responses governed by photochemical systems prompted them to come back.
Subsequent reviewers came to the conclusion that there was a lot of (although speculative) evidence that light had a substantial role in controlling fish's vertical migration.
Therefore, Point B is getting the most light and is closet to the surface.
