Read the following passage from the Biology Department at University of California, Berkeley.Northern elephant seals have reduced genetic variation because hunting by humans reduced their population size to as few as 20 individuals at the end of the 19th century. Their population has since rebounded to over 30,000, but their genes still carry the marks of this near extinction: they have much less genetic variation than a population of southern elephant seals that was not hunted as intensely.Which of the following best describes how the population has evolved?
A population of zebras experienced ten births, six deaths to predation, three deaths to disease, three individuals joining the population, and zero individuals leaving. What is happening to the population growth?

What term includes all the biotic and abiotic factors in an area?

Kaya had an organ transplant. She went to the doctor a week later, and the doctor did a blood test. Her lymphocyte count had increased. She went to the doctor a month later for the same test, and her lymphocyte count was higher. What is the best explanation as to why her lymphocyte levels were increasing?
The fossil record shows that the average size of black bears was large during cold glacial periods and got smaller during warmer time periods. What is this an example of?
What do sclerenchyma and collenchyma have in common?
Read this passage about global fishing.Global consumption of large fish has led to an exploitation of fish populations. Overfishing has led to a decline in the populations of many species of large fish including North East Arctic Cod. The graph below shows the decline in the cod population.As the human population grows and countries continue to develop, the demand for large fish has been steadily increasing. Unfortunately, the average size of the cod has decreased because the fishing nets were designed to catch the large fish and the smaller individuals could escape more easily.What is most likely happening to the genetic variation of the population of North East Arctic Cod?
Consider the cladogram.According to the cladogram, which characteristic was used to separate bony fish from amphibians?
