Which of these statements is correct about plastic and concrete?
A)Both plastic and concrete are minerals because they are natural, solid materials.
B)Both plastic and concrete are not minerals because they are made by humans.
C)Plastic is a mineral because it has a definite crystal structure but concrete is not a mineral because it is organic.
D)Plastic is not a mineral because it is not formed under the ground but concrete is a mineral because it has a definite composition.
Neither of these are minerals, B.
Its not A because, they are not natural materials but instead made up of natural materials, like a rubber tree.

Its structure is considered to be like a large dirty snowball
a) Comet
b) Meteor
c) Asteroid
pls i rly dont know
it's a comet i hope it helps
Its structure is considered to be like a large dirty snowball is Comet. Thus, option A is correct.
What is commet?Objects that are generally smaller than planet as the Asteroids, meteors, and stars have one thing in common which is they all smaller object that a planet which in turn means that the planet is bigger that them.
Asteroids are smaller in nature than planet and meteors are smaller in nature than planet and the Stars are smaller in nature than planet. Asteroids- are made from minerals and rock. Meteors- is made from space debris and rocks Comets- are made from Frozen gasses,ice, and rocks.
Asteroids, comets and meteors are small objects present in the galaxy which orbits the planets such as earth. They are very small when compared to the planets.
Some stars are bigger than certain planets therefore the group of objects comprising of stars do not explicitly represent the group of objects smaller than planets.
Therefore, Its structure is considered to be like a large dirty snowball is Comet. Thus, option A is correct.

This macromolecule forms pumps and channels within the cell membrane. They act like to let molecules in and out of the cell.
- Carbohydrates
- Lipids
- Nucleic acids
- Proteins
Answer:
The macromolecules that forms pumps and channels in the cell membrane, allowing the entry and exit of molecules to the cell are protein.
Explanation:
Membrane integral proteins are a type of macromolecule attached to the structure of the membrane and have ends in contact with the cytoplasm and the extracellular medium.
These protein molecules can act as channels and transporters or pumps, to facilitate the passage of substances through the membrane. An example of transmembrane channels are ion channels, while a protein transporter is the sodium potassium ATP-ase pump.
Membrane proteins can also act as surface receptors and enzymes linked to the cell membrane.
The other options are not correct because :
Carbohydrates can be found on the membrane bound to other molecules, such as glycoproteins and glycolipids, but they do not act as pumps or channels. Lipids have the function of being the main component of the cell membranes. Nucleic acids are found in the nucleus, and are not part of the cell membrane.Justify your choice by writing a hypothesis to explain how it has stopped the algae from making ATP, NADPH and sugars. You will be able to revise your hypothesis as you do more experiments
Answer:
Light energy.
Explanation:
Light energy cannot reach the chloroplasts, preventing ATP, NADPH and sugars because light energy is responsible for photosynthesis in algae. if light energy is not available to algae, then no photosynthesis happens and as a result no energy produced in the form of ATP, NADPH and sugars in the body of algae. so we can conclude that light energy is responsible for the preventing of production of ATP, NADPH and sugars.
GBR or Great Barrier Reef is the largest coral reef, which includes many marine organisms and corals. The GBR water is inhibiting the growth of algae mostly due to Diuron.
Diuron is an unmanageable pesticide found in the GBR. Diuron is highly toxic, persistent, and can travel long paths. Diuron interferes with photosystem II by blocking the electron transfer. PSII is an important membrane protein complex, which plays a crucial role in oxygenic photosynthesis. Thus, any interference in PSII will interfere with the production of NADPH and ATP.
However, the high temperature and paraquat can affect algae in the following ways:
Paraquat is also a herbicide, which has toxic effects on the organisms. Exposure to Paraquat has shown significant damage to the cell and inhibited cell growth. High Temperature is one of the major concerns worldwide. Due to global warming, all the organisms, terrestrial or marine are in danger.To know more about GBR, refer to the following link:

Could someone please help me with this? Sophia was fascinated while studying the role of oceans in the hydrosphere. She decided to illustrate the features of the ocean floor on a poster for her part in a group project. Identify and describe the kinds of features found on the ocean floor.
The continental shelf, slope, and rise are ocean features. The abyssal plain is the ocean floor. There are a few small deeper areas called ocean trenches beneath the ocean floor.
What is hydrosphere?A hydrosphere is a planet's total amount of water. The hydrosphere includes water on the planet's surface, underground, and in the atmosphere.
The ocean floor has a variety of features, including:
Abyssal plains are broad, flat areas of the ocean floor found at depths ranging from 4,000 to 6,000 metres.Mid-ocean ridges are long, mountainous chains that run through the ocean basins' centres.Oceanic trenches are long, narrow depressions in the ocean floor that can reach depths of 10,000 metres or more.Underwater mountains that rise steeply from the ocean floor but do not reach the surface are known as seamounts.Guyots are flat-topped seamounts that have been eroded over time by wave action.Thus, these are just a few examples of the many features found on the ocean floor.

What happens in Gilded age?The American Gilded Age was a period of immense economic change, great conflict between the old ways and brand new systems, and huge fortunes were made and lost.
The Gilded Age was a period of economic growth as the United States jumped to the lead in industrialization ahead of Britain. The nation was rapidly expanding its economy into new areas, especially heavy industry like factories, railroads, and coal mining.
As daunting as the political challenges were at the time, the Gilded Age came to an end with the reforms of the Progressive era and the New Deal. Those years saw countless changes in the rules of economic life as well as new taxes and social spending.

What is Photosynthesis?Photosynthesis is the process through which plants make their food. This process takes place in the chloroplast of plant cell. The chloroplast contains Photosystems- PSI and PSII which are responsible for photosynthesis. The hydrogen ions required by the plants are obtained by the Photolysis (splitting of water molecules) to release oxygen and hydrogen. This occurs in photosynthesis. i.e., photosystem-II.
To replace an electron in the reaction center in PSII, a molecule of water is split. This releases an electron and results in the formation of oxygen (O2) and hydrogen ions (H+) in the thylakoid space.
The hydrogen ions are pumped actively through ATP synthase. This uses up ATP energy and causes the production of ADP and phosphate. The Ubiquitin protein present in the membrane is the carrier for hydrogen ions.
Therefore, the correct options are 2 and 3.
