A poodle and a Labrador retriever can mate and have offspring. This means that these dogs are members of the same species. Because fertile offspring are produced within the same species, option D is the correct answer.
Sexual reproduction takes place in living organisms in order to produce an offspring, and here the genetic similarities are present but some changes are seen in the offspring due to the genetic cross-over and recombination. Animals from the same species can produce fertile offspring, while other species that mate may produce offspring, but they may not be fertile by nature.
When the animal of one species mate with the species of another, many times the offspring are not produced, but when they are, they are sterile in nature. Due to genetic isolation, one genus cannot reproduce with another.
hence A poodle and a Labrador retriever can mate and have offspring. This means that these dogs are members of the same species (D).

Answer:
The first thing to understand is that an HMO, or Health Maintenance Organization, is a very basic level of health insurance that will provide an affiliated person with all healthcare needs but under certain conditions and limitations. Although much less expensive than more buffed insurance plans, like PPO´s, HMO´s have a lot more conditions and limitations for patients, including that their access to physicians, and particularly certain care, and specialists, depends on the network that the HMO has to offer. A person who has an HMO and wishes to attend a specialist, or have a specialized procedure done, outside of the network provided, will require to either pay something that is called out-of-pocket expenses, or, he will be required to receive an exemption by his insurance, depending on the need.
However, what is most common for patients to do, who require to see a specialist, like a podiatrist, like is the case of Harry, and because he evidently needs it, would be to go first to his PCP, or Primary Care Physician, who would then refer him.
In order for Harry to see a podiatrist through his Health Maintenance Organization (HMO) medical insurance, the first step he will likely need to take is to obtain a referral from his primary care physician (PCP).
HMO insurance plans typically require individuals to designate a primary care physician who serves as their main point of contact for healthcare needs.
The PCP is responsible for coordinating and managing the individual's overall healthcare, including referrals to specialists like podiatrists.
To see a podiatrist, Harry will need to schedule an appointment with his primary care physician and discuss his foot pain.
The PCP will evaluate his symptoms and determine whether a referral to a podiatrist is necessary and appropriate. If the PCP agrees that a podiatrist's expertise is needed for Harry's foot pain, they will provide him with a referral.

The system that prepares foodfor absorption into the bloodstream is the digestive system. OIption B is correct.
The digestive system is made up of your digestive system and its supporting organs. The digestive system breaks down food into small molecules that your body’s cells can absorb and use. The food is broken down one by one until it’s small enough to absorb and the waste is eliminated. The digestive tract is also known as an alimentary canal. It’s a long, continuous tube that runs from your mouth to your anus.
The digestive tract is responsible for digestion and absorption. Once nutrients are digested and absorbed, they are accessible to all cells throughout the body and are used by the body’s cells in metabolism.
