4. The stars at the edges of a galaxy are rotating around the galaxy’s center at the same speed as the stars in the middle of the galaxy. How does this provide evidence of dark matter?
Dark matter absorbs light from outside the galaxy, allowing the light of the stars in the galaxy to show the orbital speeds of the stars.
Dark matter emits the light that astronomers need to see the orbital speeds of the stars.
Dark matter subtracts gravity, which allows the stars to rotate at the same speed.
Dark matter provides the gravity that allows the stars to rotate at the same speed.

Answers

Answer:

Dark matter provides the gravity that allows the stars to rotate at the same speed.

Explanation:

The stars at the edges of a galaxy are rotating around the galaxy’s center at the same speed as the stars in the middle of the galaxy. How does this provide evidence of dark matter?

Dark matter absorbs light from outside the galaxy, allowing the light of the stars in the galaxy to show the orbital speeds of the stars.

Dark matter emits the light that astronomers need to see the orbital speeds of the stars.

Dark matter subtracts gravity, which allows the stars to rotate at the same speed.

Dark matter provides the gravity that allows the stars to rotate at the same speed.

Please don't use these answers to cheat they are for help.

The statement shows that D. Dark matter provides the gravity that allows the stars to rotate at the same speed.

According to the information given in the question, it should be noted that the stars at the edges of a galaxy are rotating around the galaxy’s center at the same speed as the stars that are in the middle of the galaxy.

This implies that dark matter provides the gravity that allows the stars to rotate at the same speed. It should be noted that dark matter doesn't emit the light that astronomers need to see the orbital speeds of the stars.

12.What is an invasive species?

A native species which are added to an area

A keystone species in an environment

A non-native species added to an area

Answers

Answer:

An invasive species is an introduced organism that becomes overpopulated and negatively alters its new environment. Although their spread can have beneficial aspects, invasive species adversely affect the invaded habitats and bioregions, causing ecological, environmental, and/or economic damage.

To be invasive, a species must adapt to the new area easily. It must reproduce quickly. It must harm property, the economy, or the native plants and animals of the region. Many invasive species are introduced into a new region accidentally

A keystone species is an organism that helps define an entire ecosystem. Without its keystone species, the ecosystem would be dramatically different or cease to exist altogether. ... Any organism, from plants to fungi, may be a keystone species; they are not always the largest or most abundant species in an ecosystem

An invasive species is an organism that is not indigenous, or native, to a particular area. Invasive species can cause great economic and environmental harm to the new area.

Mecayla harvests oysters from the shallow waters of the marsh near her home. She eats the shellfish almost every day. Her brother Kendis dislikes oysters but eats local predator fish from the river three times a week. Recent water quality tests show moderate levels of heavy metals in the river and marsh. What is the most likely result of this pollutant on Mecayla and Kendis if they maintain the same diet?
Mecayla will get sick first because she eats oysters every day.
Kendis will get sick first because of less bioaccumulation.
Biomagnification will cause Kendis to become ill first.
Bioaccumulation will cause Mecayla to become ill first.

Answers

Answer: Biomagnification will cause Kendis to become ill first.

Explanation: This answer is correct because Kendis is eating the predator fish and Mecayla is only eating some oysters from the shallow water. Biomagnification causes the concentration of toxins, specifically in the predator fish, therefore Kendis will become ill first.

Mecayla harvests oysters from the shallow waters of the marsh near her home. Biomagnification will cause Kendis to become ill first.
