Explanation:
The unit of evolution is the population. A population consists of organisms of the same species that live in the same area. In terms of evolution, the population is assumed to be a relatively closed group. This means that most mating takes place within the population.
Answer:
Population change is 15
Explanation:
To calculate the change in populations, we add up the immigrants and births and the subtract the deaths and emigrant from it
Change in pop = (birth + immigrants) - (death + emigrants).
Where birth is 25, immigrants is 5, death is 10 and emigrants is 5.
Change in pop = (25+5) - (10+5)
= 30-15
Change in population is 15.
Answer:
a neurotransmitter binds to its receptor on a receiving cell
Explanation:
Answer: English
A eukaryote contains a well-defined nucleus, whereas in prokaryotes, the chromosome lies in the cytoplasm in an area called the nucleoid. In eukaryotic cells, DNA and RNA synthesis occur in a separate compartment from protein synthesis. In prokaryotic cells, both processes occur together.
Explanation: Espanol (Spanish)
Un eucariota contiene un núcleo bien definido, mientras que en los procariotas, el cromosoma se encuentra en el citoplasma en un área llamada nucleoide. En las células eucariotas, la síntesis de ADN y ARN se produce en un compartimento separado de la síntesis de proteínas. En las células procariotas, ambos procesos ocurren juntos.
Answer:
a. Viral infections may lead to inflammation between the ribs (i.e., costochondritis)
b. Viral infection
c. Viral infection may lead to the influx of chemical mediators (cytokines), increased blood flow, and movement of plasma and white blood cells (leukocytes) from the blood into the injured site
Explanation:
Costochondritis is a painful condition caused by the inflammation of the cartilage that joins the ribs to the breastbone (this joint is known as the “costochondral joint”). Costochondritis is caused by inflammation of the costochondral joint, which may be triggered by multiple causes including, among others, viral/bacterial/fungal infections, exercise or strenuous activity, chest trauma, osteoarthritis, presence of tumors, etc. Acute inflammation is the immediate immune response of the body to harmful stimuli (e.g., viral infections), which is characterized by the increased movement of white blood cells (such as neutrophils and macrophages) that rapidly travel from the blood into the injured area. This plasma contains chemical mediators like pro-inflammatory cytokines which are secreted from immune cells (e.g., Th1 cells, CD4+ cells, macrophages) in order to promote inflammation.
