B) ecosystem
C) habitat
D) pure culture
Answer:
B) Ecosystem
Explanation:
I took the quiz.
The chromosomal mutation is C. Nondisjunction .Therefore , C. Nondisjunction is correct .
There are a number of factors that can increase the risk of nondisjunction, including:
Age: The risk of nondisjunction increases with age, especially in women.
Genetic factors: People with certain genetic conditions are at increased risk of nondisjunction.
Environmental factors: Exposure to certain environmental toxins, such as radiation, can also increase the risk of nondisjunction.
There is no cure for nondisjunction, but there are a number of things that can be done to manage the symptoms and improve the quality of life of people with nondisjunction-related birth defects.
Here are some additional details about nondisjunction:
Nondisjunction can affect any chromosome, but it is most common on chromosomes 21, 13, and 18.
Nondisjunction is estimated to be the cause of 50-60% of all miscarriages.
Nondisjunction is also the cause of some stillbirths and birth defects.

Identification of mutation type, such as point mutation, silent mutation, insertion, deletion, transversion, or transition, depends on the specific changes in DNA or RNA sequences. For example, a change in a single base pair signifies a point mutation.
A thorough identification of the type of mutation seen on Chromosome 20 goes beyond merely looking at the question diagram. It depends on the specific alteration of the DNA or RNA sequences. Several types of mutations exist including point mutations, silent mutations, insertions, deletions, transversions and transitions, among others.
As an illustration, suppose the mutation involved a single base pair alteration, this would be a point mutation where one nucleotide is substituted with another. Transversions involve switching a purine with a pyrimidine or vice versa. If the mutation led to an addition or removal of a base pair, this would be termed an insertion or deletion respectively. Occasionally, a fraction of DNA from one chromosome may get transported to another chromosome or a different part of the same chromosome, a scenario known as translocation.

Deforestation, pollution and loss of natural resources all are possible due to human involvement in devastating the environment i.e. urban sprawl. Thus, correct answer is option D.
Further Explanation:
Urban sprawl is another word used for urbanization. This refers to the migration of the population from the populated towns as well as cities to the reduced density of residential development. This shift generally leads to reduction of natural resources and supplies. The final result is the spreading of a city over more and more rural land. This refers to the expansion of poorly planned and low-density development. This spreads over large amounts of land and puts long distances between storage home and work, and thus, creates high segregation between commercial and residential uses having harmful impacts on the individuals living in such regions. The wildlife and ecosystems are displaced.
Some argue that this has its benefits like making local economic growth. However, it has many uninvited consequences for the environment as well as residents like higher water and air pollution, elevated jams and fatalities in traffic, and loss of agricultural capacity. There is also an increased car dependency.

B.)No cell nucleus
C.) Cannot live in extrememe enviorments
D.)Multicellular
Answer: The correct answer is B) No cell nucleus.
Archaea is a domain that comprises of single celled microorganisms, which are prokaryotes. These organisms can survive in extremely harsh conditions like hot springs and salt water.
Example- Methanogens.
Archea was first classified as a separate group of prokaryotes under the three domain classification system of Carl Woese in 1977 that included Archaea, Bacteria, and Eukarya.
Since they are a group of prokaryotic organisms, therefore, they are devoid of nucleus and membrane bound cell organelles.
Thus, option B) is the right answer.
A. reduced water or food intake
B. infectious organisms
C. elevated or depressed blood pH
D. extreme temperatures.
Homeostasis, the body's ability to maintain internal balance, can be challenged by reduced food or water intake, infectious organisms, changes in blood pH, and extreme temperatures. These challenges can disrupt the body's normal functions and cause varying health impacts.
The body's ability to maintain a relatively constant internal environment, called homeostasis, can indeed be challenged by various factors. Reduced water or food intake can alter the balance of nutrients and hydration in the body, potentially leading to dehydration or malnutrition. Similarly, infectious organisms such as bacteria, viruses, or parasites can disrupt homeostasis by causing disease.
Elevated or depressed blood pH, which refers to the acidity or alkalinity of the blood, can disrupt bodily functions if it falls outside of a certain range. Finally, extreme temperatures can challenge body's ability to regulate its own temperature, potentially leading to conditions like hypothermia or heat stroke.
