Answers
Answer: 0.5
Explanation:
Number of people with traits = 900
Total number of individuals= 1800
To find the probability with regards to the question, we divide the number of individuals having the traits by the total population of individuals. This will be:
= 900 / 1800
= 0.5

15. Normally, tumor suppressor genes inhibit the cell cycle. How do mutated tumor suppressor genes affect the
cell cycle?
Answers
Answer:
Abnormal growth of cells.
Explanation:
Mutated tumor suppressor genes result in a loss or reduction in cell function, causing the cell to grow abnormally.
Tumor suppressor genes are the genes that regulated the cell cycle and cell division. The mutated tumor suppressor genes lead to abnormal cell growth and cancers.
What are tumor suppressor genes?Tumor suppressor genes are the anti-oncogene that regulates the cell cycle and replication. MADR-2, APC, and p-53 are the tumor suppressor genes that produce proteins that regulate the growth of the cell and cell division.
The mutation in tumor suppressor genes leads to loss of the function of suppressing abnormal cell growth resulting in tumors and cancers. This list is due to an increase in the proliferation of the cells that leads to loss of cell function showing contact inhibition.
Therefore, a mutation in the tumor suppressor genes leads to uncontrolled cell growth.

The arctic fox is uniquely adapted to its environment with white fur for camouflage, a small nose and ears and warm coat to prevent heat loss and strong paws for running and hunting. Which statement best describes how the arctic fox population may have adapted to its environment over time?
Choose the correct answer.
Foxes were bred to meet human needs for white fur.
Foxes developed smaller ears and noses in response to their cold climate. They were able to survive and pass this trait on to their offspring.
Foxes changed their fur to white to hide from predators and disguise themselves from their prey. They were able to survive and pass this trait on to their offspring.
Variation existed in the traits of the fox population. Foxes with smaller ears and noses were able to stay warmer and were more likely to survive and reproduce to pass their genes on to offspring. Over time, the fox population showed a shift to smaller ears and noses.

Sea stars can reproduce sexually and asexually. In sexual reproduction, fertilization
occurs in the water with males and females releasing sperm and eggs into the
environment.
Asexual reproduction is by fragmentation, a part of an arm and part of the central
disk becomes detached from the "parent" and develops into an independent
individual sea star. In the past, many sea stars have been "killed" by chopping them
into pieces but they have been able to regenerate and grow into more sea stars. This

Which theory of development do you prefer: Piaget or Erikson's stages? Why?
Answers
Answer:
Differences between Piaget and Erikson
Alternatively, Piaget examined the thought process of the child and how their brain responded to the environmental factors around them, rather than just crises. While Piaget focused on cognitive development, Erikson's thoughts were more focused on emotional development.
Explanation:
please give me brainlist and follow
Answer:
*This was my answer* the sections are actually really interesting if you read them.
I prefer Erikson's stage of development because Erickson really goes in-depth about each stage of life and how the challenges faced in those stages have a huge impact on human development. I also appreciate that he includes what would happen if those challenges weren't faced and how that could affect that person's future in the long run.

The relationship between the termite and bacteria is called mutualism.
What is mutualism?Mutualism is the kind of relationship between two organisms in which both organisms benefit from one another.
According to this question, termite stomachs contain bacteria that digest the fiber in wood for the termites. In turn, the bacteria are provided with a hospitable environment to carry out their life processes.
This means that both the termite and bacteria are benefitting from the relationship, hence, is a type of mutualism.

The relationship described between termites and the bacteria in their stomachs is an example of mutualism. So, the correct option is B.
What is Mutualism?A symbiotic relationship in which both organisms benefit from the interaction is known as mutualism. In this example, the bacteria give the termites the ability to digest the fiber in wood, which they are unable to digest on their own, in return for the bacteria providing the termites a hospitable environment to live and carry out their life activities.
A specific type of mutualism known as "symbiosis," in which the species involved live in close association with one another for extended periods of time, as illustrated by the termite-bacteria mutualism. These kinds of mutualistic connections are prevalent in nature and can involve a wide range of creatures, including microbes, plants, and insects.
Therefore, the correct option is B.
