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.

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.

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.

describe how the abiotic factors faced in the desert differ from those in the rainforest
Answer:
Deserts and rainforests have vastly different climates and rainfall. There is more water and sunlight in a rainforest than in a desert. etc.
Explanation:
Abiotic elements in a marine ecosystem would be salinity and ocean currents. Examples could be light, water, and temperature in a terrestrial habitat.
What are the different abiotic factorsThe animals are suited to live in the circumstances of the environment in both deserts and tropical rainforests.
Because of the heavy rain in the tropical rainforests and the severe heat in the deserts, neither tropical rainforests nor deserts are habitable for people.
The desert has low biodiversity since there are so few living things there. There may be no living things and hence no biodiversity in some desert regions.
The rainforest, on the other hand, contains the most diversity of any biome on Earth.
Therefore, the abiotic factors faced in the desert differ from those in the rainforest.
