List 3 negative impacts does plastic pollution have on the ocean?
Answers
Ingestion
And suffocation
Answer:
Negative physical impact on marine life, chemical impact on the water, and transport of native species.
Explanation:
Negative physical impact on marine life:
Plastic can be dangerous to creatures living in the ocean. Marine animals can fatally swallow plastic, become entangled in it, and even become physically impaired for the rest of their life.
Chemical impact on the water:
Plastics carry chemicals such as PCBs and DDT that can invade the water and cause harm to marine ecosystems.
Transport of native species:
Plastic can carry organisms from one part of the ocean to a relatively remote area. By introducing new organisms to an ecosystem, the flow can be disrupted and result in major consequences.

Look at the diagram of the rock cycle below.
Which part of the cycle is missing?
A.
sedimentation
B.
melting
C.
crystallization
D.
mineral integration
Answers
it’s melting
From the diagram of the rock cycle the missing part is ( B ) ; Melting
Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.
Magma is released to the earth surfaces during volcanoes therefore the missing term in the rock cycle is melting
Hence we can conclude that from the diagram of the rock cycle the missing part is Melting.

Which statement correctly describes measuring with a graduated cylinder?
The liquid in the cylinder usually forms a convex meniscus.
Measurement is taken at the bottom of the meniscus.
Measurement is taken at the top of the meniscus.
The liquid in the cylinder can only be water.
Answers
Answer:
measurement is taken at the bottom of the meniscus.
Explanation:
the first answer is not correct since water forms a convex meniscus while Mercury forms cone meniscus just as indicated in the photographs above.
I agree with the second point since we were taught that the Reading should always be taken at the bottom of the meniscus.not on top of the meniscus.
the liquid in the cylinder cannot only be water. we can either put water, Mercury or any other liquid,but not specifically water.

Star A has an apparent magnitude of –1.5 and is 12.6 light-years from Earth. Star B has an apparent magnitude of 0.4 and is 15.6 light-years from Earth.
Explain why apparent magnitude should not be used to determine which star is brighter. What information should be used instead
NEED HELP ASAP
Answers
Answer:
Absolute magnitude
Explanation:
The apparent magnitude of an object only tells us how bright an object appears from Earth. It does not tell us how bright the object is compared to other objects in the universe. For example, from Earth the planet Venus appears brighter than any star in the sky. However, Venus is really much less bright than stars; it is just very close to us.

What is litmus paper? How is it used to determine if a compound is an acid or base?
Answers
Answer:
Litmus paper is a tool used to test whether a substance is an acid or base. When a substance is dissolved in water, the resulting solution causes the litmus paper to change color. The acidity or alkalinity of a solution is determined by the concentration of hydrogen ions, or power of hydrogen, expressed as a pH value.

A. Male lions and female tigers can produce offspring.
B. Male ligers cannot produce offspring with female ligers.
C. Male and female tigers cannot grow as large as ligers.
D. Female ligers can produce offspring with male lions or tigers.
Answers
Answer:
A.
Explanation:
Because it makes sense that you NEED a Male Lion and a Female Tiger to produce a Liger. That's the only possible way and I'm 100% sure this answer is correct :)
Male lions and female tigers can produce offspring. Thus the correct option is A.
What is liger?The offspring of a lion and a tigress is called a liger.
Although they rarely meet in the wild, lions and tigers are still so closely related that they are able to interbreed, and in captivity they occasionally do. But successful interbreeding is the key, and the hybrid offspring are usually sterile and short-lived.

A. The average distance between the Earth and the Sun, or A.U., is used to measure distances within our solar system.
D. Distances to things outside of our solar system are measured in terms of light-years (ly), which are the maximum distances light can travel in a year in a vacuum.
To calculate the immense distances in the cosmos, astronomers mostly employ two methods. An astronomical unit (A.U.), often known as the average distance between the Earth and the Sun, is used as a standard measurement within our solar system. One A.U. is equivalent to 150 million kilometres or 93 million miles. Within our solar system, it is used to calculate the separations between planets, asteroids, and comets. Second, astronomers use light-years to gauge distances outside of our solar system (ly). The distance that light can cover in one year in a vacuum, or 5.88 trillion miles or 9.46 trillion kilometres, is known as a light-year. We may use this method to calculate the huge separations between stars, galaxies, and other astronomical objects. As a result, astronomers employ A.U.

Encourage students to set up a germination experiment by placing the seeds in
different conditions, such as light vs. dark, or wet vs. dry. Moreover, they need to
pot the same seed in more than one pots.
They should observe and document the changes that occur over time, including the
emergence of roots and shoots.

The seed germination investigation during the students' summer vacation involves selecting various seeds (e.g., beans, peas, sunflower) and setting up an experiment. They will place the seeds in different conditions, like light vs. dark or wet vs. dry, and pot the same seed in multiple pots. Throughout the investigation, the students are expected to carefully observe and document the changes that take place over time, including the growth of roots and shoots. This hands-on approach allows them to gain practical knowledge of seed germination and develop essential scientific skills in observation, data collection, and documentation.
What are some examples of suitable environments for bacteria?
How might bacteria avoid dying if an environment is not suitable?
How are bacterial cells different from plant and animal cells?
Describe how bacteria reproduce. How can bacteria acquire new characteristics?
Answers
Answer:
bacteria are found everywhere even in hot springs. Bacteria are different from other organisms because they don't have membranes bound organelles .they replicates to produce
Explanation:
Bacteria can live in hotter and colder temperatures than humans, but they do best in a warm, moist, protein-rich environment that is pH neutral or slightly acidic. There are exceptions, however some bacteria thrive in extreme heat or cold, while others can survive under highly acidic or extremely salty conditions.
How might bacteria avoid dying if an environment is not suitable?Many types of bacteria, if environmental conditions become unfavourable (lack of water, increase in temperature, etc), will go into a sort of dormant state, called an Endospore.
How are bacterial cells different from plant and animal cells?Because bacteria are prokaryotic, they do not have a nucleus and no membrane-bound organelles. In contrast, plants and animals are made up of eukaryotic cells, which means they have a nucleus and membrane-bound organelles like mitochondria or Golgi apparatus.
Describe how bacteria reproduce. How can bacteria acquire new characteristics?Bacteria reproduce through a process called binary fission. During binary fission, the chromosome copies itself, forming two genetically identical copies. Then, the cell enlarges and divides into two new daughter cells. The two daughter cells are identical to the parent cell.
