Answer:
D. People who live in wealthier countries tend to consume more energy per person.
Explanation:
People in wealthy countries have access to many technologies such as phones, televisions, and house appliances like coffee makers. All of these use energy. Wealthy people also tend to have larger houses that require more electricity to light and heat/cool. People in developing countries do not have access to these technologies or large houses that consume large amounts of energy. Additionally, people in poverty are unable to afford the levels of energy that wealthy citizens can. For these reasons, wealthier countries consume more energy per person.
Answer:
Invasive species are among the leading threats to native wildlife. Approximately 42 percent of threatened or endangered species are at risk due to invasive species.
Answer:
The correct answer yo get a degree in veterinary medicine.
Explanation:
In U. S. a veterinarian needs to have the proper training and degree to practice at any place like zoo or clinics. Michael needs a Doctor of Veterinary Medicine degree known as D.V.M. or V.M.D. from an accredited veterinary medicine college. It is a four years program that includes classroom studies, laboratory experience, and clinical work.
Answer:
Living organisms are adapted to their environment. This means that the way they look, the way they behave, how they are built, or their way of life makes them suited to survive and reproduce in their habitats. For example, giraffes have very long necks so that they can eat tall vegetation, which other animals cannot reach. The eyes of cats are like slits. That makes it possible for the cat's eyes to adjust to both bright light, when the slits are narrow, and to very dim light, when the slits are wide open.
Behavior is also an important adaptation. Animals inherit many kinds of adaptive behavior. In southern Africa there are small animals called meerkats, which live in large colonies. The meerkats take turns standing on their hind legs, looking up at the sky to spot birds of prey. Meanwhile, the meerkats in the rest of the colony go about their lives. You can probably think of many other features of body or behavior that help animals to lead a successful life.
In biology, an ecological niche refers to the overall role of a species in its environment. Most environments have many niches. If a niche is "empty" (no organisms are occupying it), new species are likely to evolve to occupy it. This happens by the process of natural selection.
Many fossils of different kinds of horses have been discovered, and paleontologists think that the earliest ancestor of the modern horse lived in North America more than 50 million years ago. This animal was a small padded-foot forest animal about the size of a dog. If you saw one next to a modern horse, you might not even think the two were related! As time passed, the climate of North America became drier, and the vast forests started to shrink. Grasses were evolving, and the amount grassland was increasing. Horses adapted to fill this new grassland niche. They grew taller, and their legs and feet became better adapted to sprinting in the open grasslands. Their eyes also adapted to be further back on their heads to help them to see more of the area around them. Each of these adaptations helped the evolving grassland horses to avoid predators. Their teeth also changed to be better adapted to grinding tough grassland vegetation.
