The images delivered last week show the beautiful display of lights in the southern hemisphere. These lights are the result of the solar activity known as solar wind. Traces of solar wind reach well beyond Earth and have been detected as far as Saturn.

QUESTION 4 5
4. What would most likely be the result of an invasive species entering an ecosystem?

5. Why are humans responsible for many invasive species?

Answers

#4: An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts

#5: It is not surprising that human population density is a leading cause of species invasions. Species are easily moved by human and animal (particularly domestic animal) vectors, and increasing populations residing next to protected areas simply means increasing the odds of species introduction

Write a paragraph (5-8 complete sentences) answering the prompt"How does the availability of resources in ecosystems impact ecosystems?"

Answers

5-8 Sentences on: "How Does The Availability Of Resources In Ecosystems Impact Ecosystems?"

Changing out natural resources in our environment can affect the whole entire ecosystem.  Ecosystems can change throughout time but the change may or may not affect the ecosystems.  But according to research, if the change is too fast the whole ecosystem can be destroyed.  An imbalanced or damaged ecosystem can lead to problems.  Certain resources play an important role such as sunlight and water, we need resources to survive and can also help living creatures.  These resources impact animals, plants, and insects/bugs.

P.S If you need more sentences I will edit my answer!

Answer the following questions with a picture only PLEASEEEEE.

1. What is the main source of energy for ecosystems?

2. What are some natural things that can disturb ecosystems?

Answers

Answer:

1.Photosynthesis is the process of converting light into energy

2.Natural events, such as wind, drought, flood, fire, or disease.

Explanation:

1.Since photosynthesis converts light into C-H bonds in organic material, photosynthesis is the most common source of energy in most habitats, and therefore carbon flow and destiny are inextricably related to energy flow.

2.Natural disasters such as wind, drought, storm, burning, or disease may cause disruption. These "natural occurrences" are often linked to human activities. Air and water emissions, as well as climate change effects such as temperature, rainfall, and ocean chemistry, are also examples of human disruptions.

A scientist is investigating which type of medicine would dissolve faster, a solid pill or a scoop of powder. Which hypothesis should the scientist develop given prior knowledge about surface area?
A.
Powders have more surface area and will dissolve faster.

B.
Solid pills have less surface area and will not dissolve.

C.
Solid pills have more surface area and will take longer to dissolve.

D.
Powders have less surface area and will dissolve faster.

Answers

Answer:

A.

Powders have more surface area and will dissolve faster.

Explanation:

please mark this answer as brainlest

The solute-like solids can dissolve in the solvent through the dissolution process. Powders have more surface area that permits more dissolution.

What is surface area?

The surface area is the amount of space covered or occupied by an object. It is directly dependent on the solubility and increases with an increase in the solubility.

The surface area of the powder is more compared to the solid pill and hence, the solubility of the scoop of powder is more than the pill.

Therefore, powder dissolves faster because option A. has more surface area.

Answers

Answer:

Threatened Species: A threatened species is a species at risk but not yet endangered. California sea otters were classififed as a threatened species. Laws were passed to protect the otters and now they have increased their population size.

Invasive Species: One of the main causes of extinction and endangered species is the introduction of an exotic species. New exotic species are called invasive species. Invasive species can disrupt food chains, carry disease, prey on native species directly, and out-compete native species for limited resources, like food.

Extinction: If a population decreases too much in numbers, they disappear. Extinct species mean that the species has died out and no individuals left. An example of extinction: New Zealand was once home to a bird called the Giant Moa. Humans settled as their population increased the Moa population decreased. The species is now extinct.
