BEE COLONY COLLAPSE DISORDER
Most migratory birds gather in one area and then migrate in large groups rather than individually. This behavior is a result of evolution. Which of the following is the best scientific explanation for the evolution of this
A)Birds that migrated individually or in small groups were less likely to survive and have offspring.
B)Birds that migrated individually or in small groups were more likely to find adequate food.
C)Flying in large groups allowed other bird species to join the migration.
D)Flying in large groups allowed each bird to have a better chance of finding a nesting site.
A)Birds that migrated individually or in small groups were less likely to survive and have offspring.
what are prey?
Prey animals are animals that are hunted and killed by other animals for food
Is meat a type of energy source? Explain.
Yes, meat is considered a type of energy source because it contains nutrients like protein and fat which the body can break down to generate energy when consumed; it is a key component of a balanced diet and contributes significantly to daily calorie intake.
How does running in hot weather affect the body?
t can cause dehydration, increased heart rate, and higher body temperature, leading to heat exhaustion or heat stroke.
Identify a factor that might make the volunteers' counts of migrating birds inaccurate, and explain how that factor will
One factor that might make volunteers' counts of migrating birds inaccurate is weather conditions. Poor weather, such as heavy rain, strong winds, or fog, can make it difficult for volunteers to spot birds accurately
What are predators?
Predators are organisms that hunt and kill other organisms for food. The organisms that are consumed by the predators are known as the prey. Predators can be carnivores and omnivores. Lions, tigers, sharks, and snakes, all are predators.
Give 3 negative effects of meat.
-Cardiovascular disease
-Cancer risk
-Type 2 diabetes risk
What adaptations help the body cope with running in hot weather?
The body improves sweat efficiency, increases blood volume, and enhances cooling through evaporation with training.
Where can we find a Rufous Hare-Wallaby?
Western Australia
Give 3 positive effects of meat.
-High protein content
-Iron absorption
-Zinc source
How does running in heat impact muscle performance and recovery?
It reduces muscle efficiency, lowers oxygen delivery, and increases recovery time due to heat stress.
what are the importance of bees?
Bees are important pollinators that help plants reproduce, which makes food production possible. They also support biodiversity and the ecosystem, and provide food and other products.
How does habitat disruption affect migratory bird populations and their survival?
Habitat disruption, such as deforestation, urbanization, and climate change, can interfere with the birds' migratory routes, breeding grounds, and food sources
What is the role of predators in controlling the population of prey species?
Predators help control the population of prey species by keeping their numbers in check. By hunting and eating prey, predators prevent any one species from becoming too numerous, which could lead to overgrazing or depletion of resources. This balance helps maintain a healthy ecosystem and supports biodiversity by allowing various species to thrive.
How does protein affect our body?
it helps build and repair tissues, maintain fluid and pH balance, and keep your immune system strong.
What risks does electrolyte imbalance pose while running in heat?
It can cause muscle cramping, impaired nerve function, and reduce performance, increasing the risk of heat-related illnesses.
why do we need bees for our environment to survive?
Bees are essential to the environment because they pollinate plants, which helps maintain biodiversity and food security.
How do migratory birds navigate over long distances using environmental cues?
Migratory birds use a combination of environmental cues to navigate. These include the Earth's magnetic field, the position of the sun during the day, and the stars at night.
What is the ecological role of apex predators in maintaining biodiversity, and how do their removal or decline impact ecosystem dynamics and the species that depend on them?
This question involves understanding the intricate relationships within ecosystems, particularly the top predators' influence on prey populations, and the cascading effects of their absence. It also touches on concepts like trophic cascades and the balance of food webs.
Why is meat important to our daily diet?
it is a readily available, concentrated source of high-quality protein, essential vitamins like B12, and minerals like iron and zinc, which are crucial for various bodily functions including muscle growth, red blood cell production, and immune system health.
A runner runs for an hour on a hot and humid day (air temperature 35°C, air humidity of 60%) without drinking any water. This runner is at risk of both dehydration and heat stroke.
What would be the effect of drinking water during the run on the runner's risk of dehydration and heat stroke?
Drinking water would reduce the risk of dehydration but not heat stroke
