The correct option is A.
What is biological marker?A biomarker is an objective measure of what is going on in a cell or organism at any given time. Biomarkers can serve as health-related early warning systems.
To create knockout mice, researchers insert artificial DNA into the chromosomes contained in the nuclei of ES cells using one of two methods.
Both methods are performed in vitro, that is, on cultured cells grown in a laboratory setting.
After introducing a DNA construct into ES cells that mutagenizes a specific gene by inserting a drug resistance marker, the cells that have incorporated the transgene via homologous recombination grow in the presence of the drug and are injected into a host blastocyst.

a mass extinctions is
Answer:
Mass extinction is when biodiversity or species in a living habitat decreases to about three-fourths of its original number or to none. Such an event is identified by a sharp change in the diversity and abundance of multicellular organisms. It occurs when the rate of extinction increases with respect to the rate of speciation. Mass extinctions are usually associated with organisms that are macroscopic rather than microscopic. Examples of mass extinctions are Permian extinction of marine species, and Cretaceous extinction of various species, including dinosaurs.
There are almost 10,000 known bird species on the planet. How did they evolve into so many unique forms?
Answer:
Natural selection.
Explanation:
Imagine in the beginning there was a single species of bird. Naturally, this bird had to expand to the rest of the world, and was distanced as the continents drifted off. But this bird had to cope with various climates and environments. So the bird would gradually mutate over time. The bird in the jungles of central america would develop different colors and a shaped beak, and would better help it survive. This led to being the new normal for birds of this area. It would evolve to cover all the surviving birds in the region, until it is so drastically changed then it is a new species. There are so many different environments, each with its own challenges to overcome, so so many different bird evolve to survive them.

The fossil presence of anatomically modern humans in ________ demonstrates that our ancestors were capable of substantial water crossings by 40,000 years ago.
Answer:
The correct answer is - Africa.
Explanation:
Scientists found the fossils of modern humans called Mota an ancient man who lived around 40000 to 45000 years ago in Ethiopia. It was the first DNA isolated from Africa.
This DNA sample says that the Europeans have 6% of the DNA of this modern human, which suggests that there was substantial migration of people into Africa from Europe and the middle east by water crossings.
Cystic fibrosis is an autosomal recessive disorder where a chloride ion membrane channel protein doesn't function properly. People with cystic fibrosis suffer from chronic lung infections that make breathing very difficult. They also suffer from other issues such as an inability to produce enough digestive enzymes due to problems with pancreas cells. Suppose that Chris and Shannon are both carrier of cystic fibrosis (carriers have the allele but do not exhibit the disorder). What is Chris' genotype for the cystic fibrosis gene
Answer: Typically, the genotype in those patients consists of at least one very mild mutation uncharacteristic for CF patients. These are predominantly missense or splice variants, belonging to classes IV or V producing variable amounts of functional CFTR protein at the apical membrane.

What happens to a population when its size is equal to the carrying capacity?
a. Its size fluctuates wildly.
b. It increases in size.
c. Its size stays steady.
d. It decreases in size.
Answer:
C
Explanation:
When a population reachs its carrying capacity it will slow down and become steady due to the population reaching its limit on food, water, etc. and they can only feed so many.
When population size is equal to the carrying capacity then "Its size stays steady".
What is population ?A population means the total number of individuals who cohabit in a certain area.
What is steady-state?A biofilm that exhibits no net growth or degradation over time is usually referred to as a steady-state biofilm.
A population might slow down and stabilize once it reaches it's own carrying capacity since it will no longer be able to consume as much food, water, and other resources.
Therefore, the correct answer will be option (c)

gained today:
Ms. AB was traveling and caught a nasty flu on the plane. But because she had work and school she could not take any
time off to rest during her flu. 2 weeks after she contracted the flu, she no longer had the fever and sore throat, but her
nose was still stuffy, and she was suffering from sinus headaches. She went to her doctor, who diagnosed her with a
sinus infection and prescribed her a course of antibiotics. Ms. ABC took the 7 days of antibiotic therapy, but she is now
back at her doctor's office with a yeast infection and diarrhea. Explain, why Ms. ABC developed the sinus infection. Then
explain why she developed a yeast infection and diarrhea after the course of antibiotics
Answer:
Antibiotics killed the bacteria that cause infection but they can also kill beneficial bacteria . thus Ms ABC developed a yeast infection and diarrhea after course of antibiotics because antibiotics distrub natural balance of beneficial bacteria in her intestine.
Ms. ABC developed a yeast infection and diarrhea after the course of antibiotics because the exposure to antibiotics may kill beneficial bacteria which prevent other diseases to occurs in the body.
What is an Antibiotic?Antibiotics may be defined as a type of medicine that significantly inhibit the growth of microorganisms especially bacteria inside the body of living organisms. Such type of antimicrobial substance may either kill or inhibit the growth of bacteria.
It is the most prevalent kind of antibacterial agent for conflicting bacterial infections, and antibiotic medications are tremendously utilized in the treatment and prevention of such infections.
With the effect of antibiotics, beneficial bacterial species that are living in the intestine may also be killed. Due to this, Ms. ABC becomes susceptible to other types of infections like yeast and diarrhea.
Therefore, exposure to antibiotics may significantly kill beneficial bacteria which prevent other diseases to occurs in the body.
