Answer:
Your heart is a single organ, but it acts as a double pump. The first pump carries oxygen-poor blood to your lungs, where it unloads carbon dioxide and picks up oxygen. ... The second pump delivers oxygen-rich blood to every part of your body. Blood needing more oxygen is sent back to the heart to begin the cycle again.

Answer:
Grass
Explanation:
Biotic means living. There are some obvious abiotic factors here. The only gray area is what "soil" encompasses
grass-Biotic means living, all of the other choices are not living, and would therefore be abiotic factors
This is because it is a living thing (performs photosynthesis and cellular respiration).

Which of the following statements best describes a benefit of sexual reproduction?
It creates many offspring in a short amount of time.
A
B
It prevents mutations from being passed on to offspring.
С
It results in diversity of the species that enhances the probability of survival.
D
It ensures the offspring will receive only the best traits from each of the parents.
Among the listed options, we can conclude that option C which states that "It results in the diversity of the species that enhances the probability of survival." is correct.
Sexual reproduction offers organisms an advantage over those who undergo Asexual reproduction. Though there are benefits and drawbacks to each method, Sexual reproduction is a method that is better adapted to a changing environment and promotes the faster evolution of a species.
The main benefit of sexual reproduction is that it allows for a greater diversity of the species which enhances the probability of survival. This is due to the fact that sexual reproduction leads to varying combinations of alleles for specific traits, which coupled with selective reproduction (the ability of a member of the species to choose a spouse with desirable traits) leads to offspring who over time are increasingly better adapted to life in the given environment, with specific traits tailored for survival.

Answer:
Because there are two rounds of division without duplication in between, the genetic content is cut in half. Each of the 4 daughter cells will only end up with half of the genetic content of the parent cell. Therefore, after meiosis, the daughter cells would have only 12 chromosomes each.

which high grade, foliated metamorphic rock has visible crystals?
Answer:
Gneiss
Explanation:
Gneiss forms at the highest pressures and temperatures and has crystals large enough to see with the unaided eye. Gneiss features minerals that have separated into bands of different colors. The bands of colors are what define foliation within gneiss.
Hope this helps! : )
Gneiss crystals are large enough to be seen without magnification. Gneiss has color-banded minerals. Color bands define gneiss foliation.
What is Gneiss?The metamorphic rock known as gneiss is quite common and can be found all over the world. It is produced when procedures of high temperature and high pressure metamorphism are applied to formations that are made up of rocks that are either igneous or sedimentary in nature.
Gneiss is formed at temperatures and pressures that are higher than those required to make schist. Gneiss almost always has a banded texture that is defined by alternating darker and lighter colored bands and does not have a clear cleavage. Gneiss may also lack a distinct cleavage.
Gneisses are frequently found in the crust of continental shields that formed in the distant past. Gneisses like the Acasta Gneiss are among the oldest rocks on Earth and are classified as Proterozoic.

After first exposure to an antigen, about how long does it take for antibodies to reach a detectable level?
2. What could explain the significant increase in antibodies to non-Lyme disease antigens (blue line)?
3. Lyme disease patients who are treated with antibiotics quickly usually do much better than those who are treated later. Why do you think this is the case?
4. Why doesn’t the Antibodies in Lyme Disease Antigens (orange line) decrease after the first immune response, compared to non-Lyme Disease Antigens (blue line)?
5. Professor Dr. Utpal Pal studied the Borrelia burgdorferi bacterium at the University of Maryland. Dr. Pal found that Lyme disease is caused by your immune system. When the body is infected with Lyme disease, it overreacts causing inflammation in the joints. Although antibiotic resistance has not been observed for B. burgdorferi, create an argument defending the control of antibiotic use to the public. Analyze the data in the graph below by answering the following questions. Be sure to use complete sentences.
After first exposure to an antigen, it can take about three weeks for antibodies to reach a detectable level. The body will react to disease by creating antibodies and testing their effectiveness against the unknown antigen.
Antibodies are the body's way of fighting off foreign threats. Also known as immunoglobulin, they detect and attack pathogenic bacteria and viruses. These antibodies detect a protein that is unique to the surface of the pathogen called the antigen.
At times, we can see an increase in antibodies for one disease, for example, Lyme disease, in the presence of non-Lyme disease antigens. This is often due to antigenic variation, which is a method used by pathogens to mask their respective antigens. There are also general use antibodies that will increase in reaction to any pathogen.
As with any illness, a patient who receives treatment sooner will fare better than those whose treatment is delayed. This is due to the fact that earlier treatment with antibiotics will allow the body to fight off the infection before the bacteria can reproduce further.
After the first immune response, antigen-specific antibodies will remain for some time to provide the body with "immunity" to the pathogen, while general-purpose antibodies will return to a base value.
