What effects can an invasive species have on an ecosystem?Choose all that apply
A - Overpopulation due to no natural predators.
B - Reduced resources for native organisms.
C - Introducing new organisms ALWAYS benefits the native organisms in an ecosystem.
D - Reduced survival rates of native organisms.
Answer:
It should be D.
Explanation:
The invasive species will negatively effect the ecosystem and the natural predator in the area. Like the Blue Lobster problem in Maine.
A and B are effects that invasive species can have on an ecosystem.
What is an invasive species?An invasive species is a species that is introduced to an ecosystem where it is not native and has a harmful impact on the environment, the economy, or human health.
These species are often highly adaptable and can outcompete native species for resources, leading to reduced survival rates and changes in the balance of the ecosystem. Invasive species can also cause indirect harm by disrupting food webs and changing the abundance of other species. Human activities, such as trade and travel, are the primary causes of the spread of invasive species. In order to prevent further harm, efforts are made to control and manage populations of invasive species and to prevent their spread to new areas.

A tree frog population lives in the canopy of a tropical rainforest.A mutation occurs in the species that causes stripes on their legs. Which of the following factors has the greatest effect on whether leg stripes will become more common in the tree frog population?
A.If the reproduction rate of the tree frog population remains constant.
B.If the new phenotype is present in more females than males.
C.If the new phenotype increases the survival of the tree frogs in their environment. D.If enough food and water are available in the rainforest canopy to support the tree frog population.
choose a,b,c,or d please actally answer
Answer:
C
Explanation:
if the phenotype increases the survival, then they are better adapted and will survive until reproductive age, when they reproduce, their genes are passed on and their offspring will have the same phenotype. this continues for many generations and the new phenotype will be common. ( this whole process is known as natural selection).

Which description properly describes a step involved in cellular respiration?
Select one:
a. Glucose is created, then the energy gained is transferred to the energy molecule.
b. Carbon dioxide and water are released after the energy molecule is charged.
c. Water is divided into carbon dioxide and glucose.
d. Oxygen is combined with ATP to energize it.
Answer:
A. Glucose is created, then the energy gained is transferred to the energy molecule.
Explanation:
Respiration could be a metabolism that happens altogether to living organisms. In humans, the energy is made within the body by respiration once one molecule of aldohexose is weakened into six greenhouse gas and 6 water molecules in the presence of oxygen.

Which statement describes one of Wegener’s ideas that contributed to the theory of continental drift?
A. The continents drifted apart due to repeated meteor impacts.
B. The continents were once connected as one landmass.
C. The continents have moved apart very quickly due to earthquakes.
D. The continents are magnetically pulled toward or pushed away from one another.
Answer:
Option B
The continents were once connected as one landmass.
Explanation:
The theory of continental drift suggests that all the continents on the planet were once connected, forming a supercontinent. However, over time they drifted apart as a result of some internal forces of the earth.
The most appropriate option that shows this is option B: The continents were once connected as one landmass.
This statement describes one of Alfred Wegener's ideas that suggests that a very long time ago, the continents were once connected in a landlocked mass. The fact that the continents are separated now shows that the continents are continuously shifting position on the earth's surface
The statement that describes one of Wegener’s ideas that contributed to the theory of continental drift is the continents were once connected as one landmass. The correct option is B.
What is continental drift?Continental drift theory states that the motion of the earth results from the movement of tectonic plates. The theory tells that the different continents were fitting together.
According to the theory of continental drift, the world's continents were once joined together to form a supercontinent. However, because to some underlying earth factors, they gradually drifted apart over time.
According to one of Alfred Wegener's theories, the continents were previously linked together as a landlocked mass a very long time ago. The separation of the continents indicates that their positions on the surface of the globe are constantly altering.
Thus, the correct option is B. The continents were once connected as one landmass.

why is the skin Cancer rates in Australia so high?
Answer: There's a lot of sun all year round
Explanation:
Australia is close to the equator which means it is hotter as the sun is closer. The heat from the sun damages our skin and causes skin cancer. In Australia the rates would be high because people are exposed to the sun more.
How does the formation of coal relate to the rock cycle
Answer:

Explanation:
How does light intensity and distance affect the rate of photosynthesis? How do you know?
Answer:
Explanation:
Light provides the energy needed for photosynthesis. Increasing the light intensity increases the rate of photosynthesis, provided plenty of carbon dioxide and water are available. ... This states that the intensity of light is inversely proportional to the square of the distance from the source.
The factors affecting the rate of photosynthesis are:
1. Light:
Light provides the energy needed for photosynthesis. Light intensity. Without enough light, a plant cannot photosynthesize very quickly - even if there is plenty of water and carbon dioxide.Increasing the light intensity increases the rate of photosynthesis, provided plenty of carbon dioxide and water are available.2. Distance:
There is an inverse relationship between distance and light intensity - as the distance increases, light intensity decreases. This is because as the distance away from a light source increases, photons of light become spread over a wider area.Learn more:
