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.

Which of the following would provide the most energy in an ecosystem?
A. Omnivore
B. Carnivore
C. Producers
D. Herbivores
Answer:
The one that would provide the most energy in an ecosystem are producers!
Explanation: On the food chain and in the ecosystem they contain the most energy. About 90% is lost through heat and and movement of the animals. Lets say you have 10,000 kelo calories, then you have the producer and then your 3 animals, this means the last one only gets 10 kelo calories!
The following would provide the most energy in an ecosystem: producers, which are in Option c, as the producers are organisms such as algae and green plants that can synthesize their own food using the energy of the sun.
What is the significance of the producers in energy production?Producers include plants, algae, and some bacteria that serve as the primary source of energy, converting light or chemical energy into a form of food such as glucose, and in every ecosystem, the producers have many important roles. Herbivores and carnivores all depend on them, both directly and indirectly.
Hence, the following would provide the most energy in an ecosystem: producers, which are in Option c, as the producers are organisms such as algae and green plants that can synthesize their own food using the energy of the sun.

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 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.
