1. Binary fission is observed in (a) Hydra (b) yeast (c) Amoeba (d) human being

Answers

Answer:

Amoeba

Explanation:

Binary fission is a type of asexual reproduction in which a cell divides to form two cells. It occurs in organisms that are protozoans. This means that two new daughter cells are formed in the process.

During the process of binary fission, the cell Is divided into two, this means that the DNA is replicated in both parts so that each of these cells becomes an independent organism, this means that they would be able to survive and function on their own.

Hence from the options listed, binary fission is observed in Amoeba

compare and contrast the rock cycle and the carbon cycle

Answers

Answer:

The rock cycle and water cycle overlap with erosion, transporting, and deposition.carbon atoms are used repeatedly on Earth and cycled between the atmosphere, hydrosphere, biosphere, and lithosphere through processes

Explanation:

The rock cycle and the carbon cycle are two different types of natural cycles that occur on earth. The difference include components, processes, time scale, human impact, and environmental implications.

What is the difference between rock cycle and carbon cycle?

The rock cycle is a continuous process that occurs over millions of years, during which rocks are transformed from one type to another. There are three major types of rocks: igneous, sedimentary, and metamorphic. Each type of rock is formed through a different process.

The carbon cycle is the process by which carbon is cycled between the atmosphere, oceans, and living organisms. Carbon is essential for life, and is found in all living organisms. The carbon cycle is driven by photosynthesis, respiration, and decomposition.

During photosynthesis, plants absorb carbon dioxide from the atmosphere and use it to build organic molecules. These organic molecules are then consumed by other organisms, and carbon is transferred up the food chain.

When organisms die, their bodies are decomposed by bacteria and fungi, which release carbon dioxide back into the atmosphere.

In addition, carbon is stored in fossil fuels such as coal, oil, and natural gas, which are formed from the remains of ancient plants and animals. When these fuels are burned, carbon is released into the atmosphere, contributing to global warming.
