Describe the stages of invasion up to and including the spread stage. Also, include one barrier to could make
an invasion fail and briefly describe it.
Answer:
Introduction, naturalization, colonization, and dispersal or spreading.
Explanation:
There are four main stages of invasion i.e. introduction, naturalization, colonization, and dispersal or spreading. In the first stage, the specie is introduced in the environment, in the second stage the specie adopt the environment, in the third stage the specie started growth and make colonies to increase its population and in the last stage the specie disperse in the environment through different means and spreading of that organism occur. The failing of adaptation to the environmental conditions leads to the failing of invasion of a specie.

What is the difference between rotation and revolution? Which one determines the planets length of day and which one determines the length of the year
Answer:
Rotation is when an item or object (specifically the earth) rotates on it's axis.
Revolution is when an item (the earth) orbits or "revolves" around another one (the sun).
The rotation of the earth determines how long a day lasts while the revolution (or orbit) determines how long a year lasts (with all of the season).
Also you don't have to put the ones in the parentheses ()

Cyanobacteria can cluster together into colonies called _______, with some discovered in Western Australia that are 3.5 billion years old. Cyanobacteria produce oxygen and convert sunlight to energy using _______. Plants and arthropods didn't make the transition to land until near the end of the _______ Period. Diverse multicellular eukaryotes didn't appear until the _______ period. A large multicellular eukaryote requires more _______ to survive than a single-cell eukaryote. Respond to the following based on your reading. Describe the biological chemical processes that were responsible for producing oxygen in Earth's atmosphere, eventually leading to the Cambrian Explosion. Explain the importance of oxygen in the evolution of large multicellular animal life.
Answer:
1.) stromatolites
2.) photosynthesis
3.) Ordovician
4.) Cambrian
5.) oxygen
6.) As Earth cooled, carbon dioxide dissolved in the early ocean. Cyanobacteria consumed carbon dioxide and converted it to oxygen. Methane was removed from the atmosphere as oxygen was produced, eventually leading to the Cambrian Explosion.
7.) Metabolic processes that use oxygen produce more energy than anaerobic metabolism. Simple diffusion of oxygen would limit the size of a multicellular eukaryote, but animals evolved ways to transport oxygen to their tissues, which permitted an increase in size.

Gonorrhea and Antibiotic Resistance
The CDC has categorized several infectious agents based on the seriousness of their antibiotic resistance. Neisseria gonorrhoeae, the causative agent of gonorrhea, is one of several agents in the "Urgent Threat" category. Gonorrhea is also the second most common reportable disease in the United States. This makes gonorrhea a significant public health concern. Please locate this article through an online search engine: Kirkcaldy RD, Harvey A Papp JR. et al. Neisseria gonorrhoeae Antimicrobial Susceptibility Surveillance - The Gonococcal Isolate Surveillance Project, 27 Sites United States. 2014. MMWR Surveill Summ 2016;65/No SS-7):1-19. DOI: http://dx.dol.org/10.15585/mmwr.ss6507at. Read the article thoroughly, and then answer these questions about the agent of gonorrhea and its potential for antibiotic resistance. eBook erences
Select all of the characteristics below that apply to Neisseria gonorrhoeae. (NOTE: Please change all question marks to checkmarks for correct answers or empty boxes for incorrect answers.)
a. It is a virus.
b. It usually affects the urogenital system but may also affect the eyes.
c. It is a gram-positive bacterium.
d. It must be grown on selective and enriched media.
e. It is gram-negative bacterium.
f. It can cause asymptomatic infections.
g. It usually affects the nervous system.
h. It is a yeast.
Answer:
b. It usually affects the urogenital system but may also affect the eyes.
e. It is gram-negative bacterium.
d. It must be grown on selective and enriched media.
g. It usually affects the nervous system.
f. It can cause asymptomatic infections.
Explanation:
Neisseria gonorrhoeae is a gram negative bacteria known to cause the sexually transmitted infection called Gonorrhea. Gonorrhea is easily treated with antibiotics, as long as the patient seeks early care and discovers the disease early on, as it can be asymptomatic, especially in women. When left untreated, Neisseria gonorrhoeae can infect the nervous system, causing many problems and even leading to death.
Despite being known to attack the urogenital system, this bacteria can attack the eyes generating gonococcal conjunctivitis, which is also sexually transmitted.
Neisseria gonorrhoeae is a fastidious bacteria, which means that it only grows in specific, selective and enriched culture media.

Night blindness (n) is a sex-linked recessive trait. A woman who is night blind marries a man who is not night blind. What are the genotypes of both individuals?
Answer:
Genotype of night blind woman - XnXn
Genotype of normal man - XY
Explanation:
Given
Night blindness (n) is a sex-linked recessive trait. Let us say it is X linked recessive
In this case a man with XY genotype having a diseased X allele will be night blind while a woman will have night blindness if both the X allele are diseased . In case if only one X allele is diseased in women then, she will be a carrier of night blindness defect
Genotype of night blind woman - XnXn
Genotype of normal man - XY

Leigh's disease is a mitochondrially inherited disease with symptoms that include seizures, fatigue, impaired reflexes, breathing problems, and ataxia. The pedigree shows the presence of Leigh's disease in three generations. Individual 4 had two daughters and one son, and individual 6 had one daughter and two sons. Which of the individuals indicated are affected by Leigh's disease
About the question:
You will find the pedigree in the attached files
Answer:
individual 4 → Affected woman → Black circleindividual 5 → Affected woman or man → Black circle or squareindividual 7 → Healthy woman → Empty circleindividual 10 → Affected boy → Black SquareExplanation:
Mitochondrial inheritance is the transmission of a disease or a trait from the maternal line.
Most of the DNI is in the nucleus, but there is also DNI in mitochondria. Sperm cells hardly transfer mitochondrial genes to the progeny, so mitochondrial DNI is mostly inherited from the maternal side. If there exists any mutation in this mitochondrial DNI, the whole progeny of the mutated woman will be affected, as they will get the mother genotype carrying the mutation. On the contrary, if an affected man is carrying a mutation in mitochondrial DNI, non of their descendants will get the disease.
Before answering the question, let us remember the pedigree symbols.
Squares represent Males/Men Circles represent Females/WomenEmpty symbols represent healthy/non-affected individualsSolid black symbols represent sick/affected individualsIn the exposed pedigree, we can see that the mother is affected by the disease (individual number 2), so all her children are also affected (individuals 4, 5, and 6) because the disease is mitochondrially inherited.
Individual 3 is a healthy man, so individual 4 must be an affected woman (Black circle). As she is the one affected, then all her children will also be affected. This couple had one boy and two girls. Individuals 8 and 9 are girls (circle), so individual 10 must be the affected boy (black square).
On the other hand, individual 6 is an affected man (black square), son of individuals 1 and 2. This man couples with a woman, and they have all healthy children. So this woman (individual 7) must be healthy. Even though the man is affected, all their children are not because their mother (7) is not. Remember that sperm cells do not transmit the mitochondrial genes to the progeny.
And finally, individual number 5 might be either a man or a woman. In any case, this person is also affected by Leigh's disease.

Which wave interaction is shown by the diagram? o absorption o diffraction o reflection o refraction
Answer:I agree
Explanation:
Diffraction wave interaction is shown by the diagram.
What do you mean by diffraction?Diffraction is defined as the interference or bending of waves around the corners of an obstacle or through an aperture into the region of geometrical shadow of the obstacle/aperture.
The most common example of diffraction occurs with water waves which bend around a fixed object. Light bends similarly around the edge of an object. The animation shows wave fronts passing through two small openings.
Diffraction results from the interference of an infinite number of waves emitted by a continuous distribution of source points. According to Huygens' principle every point on a wave front of light can be considered to be a secondary source of spherical wavelets.
