Answer:

Yes! I think modern whales are different from whales of the past.

the first cells likely to encounter a pathogen, such as phagocytes, are professional antigen presenting cells (apcs). this means
Zepler [3.9K]

Professional antigen-presenting cells, such as phagocytes, are the first cells to encounter a pathogen (apcs). This means they have the ability to activate cells of the adaptive immune system.

<h3>What is meant by Pathogen?</h3>
  • A pathogen is an organism that infects its host with disease, and the severity of the disease symptoms is referred to as virulence.
  • Pathogens include viruses, bacteria, unicellular and multicellular eukaryotes, and a wide range of other organisms.
  • The bone marrow of an average healthy adult generates 100 billion new neutrophils per day. Because there are so many neutrophils in the body at any given time, they are often the first cells to reach the site of an infection.
  • Long thought to be a component of the innate immune system, complement has recently emerged as an important regulator of the adaptive immune response.

Therefore the correct option is D)  can activate cells of the adaptive immune system.

Could producers survive without consumers? explain why or why not
arlik [135]
Producers could not survive without consumers. Produces rely on consumers to purchase their product, if no one buy their product, then the producer has no money to even produce anything. This like a car, the car is the producer, and the gas is the consumer, the car will not work unless there is gas. So a producer will not survive without the consumer.

dexar [7]
 Vision is the least developed of a newborn baby's senses. <span>The visual capacity of the baby develops progressively in the first 8 months. From then on, the baby's vision will be as good as that of the adult. Although at birth, the eyes of the newborn have the physical ability to see without problems, your brain is not yet ready to process all that information; that's why he sees everything blurred. With the development of the brain, your visual ability improves.</span>
