The Koala (Phascolarctos cinereus) is a native species of Australia that belongs to the marsupial family Phascolarctidae. Koalas are known for their distinctive appearance, including their large ears, round faces, and fluffy, gray-brown fur.

Koalas have a specialized niche in their ecosystem, as they are highly specialized herbivores that feed exclusively on eucalyptus leaves. They have a long, sticky tongue that allows them to extract nutrients from the leaves, and they have a unique digestive system that is able to process the toxic compounds found in eucalyptus leaves.

The Koala's niche has a significant impact on the ecosystem. Eucalyptus leaves are an important food source for many other animals, including birds and insects, so the Koala's feeding habits help to maintain a balance in the ecosystem.

Additionally, Koalas play a role in seed dispersal, as they often defecate the seeds from eucalyptus leaves in their feces, which helps to spread the seeds and promote new growth.

Overall, the Koala's niche as a specialized herbivore that feeds on eucalyptus leaves is important for maintaining the health and balance of their ecosystem, and it helps to support the survival of many other species in the region.

Answer:

n the different regions of the plant body parenchyma cells are involved in different functions. On this basis, following types of parenchyma can be recognised.

Chlorenchyma is the parenchyma in which the cells contain large number of chloroplasts. Chlorenchyma takes part in photosynthesis. It occurs in the leaves and other green parts of the plant body.

Prosenchyma is a type of parenchyma where cells are elongated with tapering ends.

Arenchyma is the parenchyma in which the cells enclose large intercellular spaces that are filled with air. Aerenchyma helps in buoyancy and respiration. It is characteristically found in aquatic floating plants.

Vascular parenchyma is the parenchyma, which is found associated with the vascular tissues xylem and phloem. Accordingly, it is distinguished into xylem parenchyma and phloem parenchyma.

Medullary parenchyma is the parenchyma, which is found radially arranged in between the vascular bundles in the stem. It is meant for storage of reserve food.

Conjunctive parenchyma is the parenchyma, which occurs in the root system. It is specially meant for storage of water.

Armed parenchyma is the parenchyma, which is found in the epidermis of leaves in some gymnosperms. The cells have many spiny projections. It is defensive in function.

The term describes cells in both plant and animal tissues. In plants, parenchyma cells are a distinct type of tissue that can grow and divide and they have a thin cell wall. They make up flowers, leaves, and the inner parts of roots and stems that grow and divide. These cells secrete sap, exchange gases, and conduct photo synthesis. Plant parenchyma is classified into 4 shapes: polyhedral, stellate, elongated, and lobed.

In animals, parenchymal cells are the functional cells within the organism. This does not include those that have structural and/or protective functions like bone cells that make up a skeleton. In the brain, the parenchyma consists of neurons and glial cells. In addition, the cancer cells in tumors that are not involved with blood vessels are called parenchyma.

Answer:

a. Photosynthetic parenchyma: it is commonly found under the epidermis, where light is more intense. It is specialized in photosynthesis thanks to the many chloroplasts present in the cells.

b. Storage parenchyma: They are mostly found in solution, such as lipids, proteins, and others. Their function is to synthesize and store a number of substances.

According to decay theory, forgetting occurs because of the passage of time.

Sigmund Freud's concept of repression reflects the idea of retrieval failure.

Forgetting is a common phenomenon in human memory, and decay theory suggests that it happens due to the natural fading or weakening of memories over time. When information is encoded into our memory, it creates neural connections and pathways in the brain. However, these connections can gradually weaken or decay if they are not reinforced or accessed frequently.

The main idea behind decay theory is that memories that are not regularly reinforced or retrieved may gradually decay, becoming more difficult to retrieve accurately. This decay occurs at the neural level, as the connections between neurons weaken over time, making the memory traces less effective in retrieving the information. As a result, memories that are not actively maintained through rehearsal or retrieval can become less accessible and eventually fade away.

Repression is a concept introduced by Sigmund Freud in psychoanalytic theory, and it refers to the unconscious blocking of traumatic or distressing memories from conscious awareness. According to Freud, individuals may repress memories that are too threatening or painful to consciously remember, pushing them into the unconscious mind.

Repression aligns with the concept of retrieval failure because the memories that have been repressed are not readily accessible to conscious retrieval. While the memories may still exist in the unconscious, they are effectively blocked or "forgotten" from the conscious awareness.

When attempts are made to retrieve repressed memories, they may remain inaccessible due to the psychological defense mechanism of repression. These memories are effectively "hidden" from conscious recall, making retrieval difficult or even impossible without specialized therapeutic techniques.

Answer: Life would cease to exist.

Explanation:

The carbon elements is one of the most important elements in the compound that make up living organisms. It is found: in the remains of living organisms; as fossil fuels such as coal, coke and natural gas; as inorganic salts such as carbonates; in water bodies and as gas carbondioxide which makes up 0.03% of air.

Carbon is continuously being circulated in the atmosphere through a process called the CARBON CYCLE. This involves the removal and addition of carbon to the carbondioxide in the atmosphere.

Life would indeed cease to exist if this carbon cycle stops due to the importance of carbon to functioning of living organisms. Important processes which bring about the recycling of carbon between living ( biotic) and non living (abiotic) components of an ecosystem are:

--> photosynthesis: the process used by green plants to remove carbon through carbondioxide from the atmosphere for manufacturing of their food.

--> respiration: animals respire to break down sugar leading to liberation of carbondioxide and water as wastes

--> and decay: decomposers feeds on remains and waste to bring about decay, thus complex carbon compounds are broken down to set free carbondioxide which returns to the atmosphere.

All the above processes are carried out by living organisms to maintain a functioning ecosystem by enabling a linear flow of energy through it.

The ATPase subunit of chromatin-remodeling complexes is called DNA helicase.

DNA helicases are enzymes responsible for unwinding the double helix structure of DNA by breaking hydrogen bonds between complementary nucleotide bases. In the context of chromatin remodeling, DNA helicases play a crucial role in altering the structure and accessibility of DNA by unwinding the tightly packaged nucleosomes. By utilizing the energy derived from ATP hydrolysis, DNA helicases disrupt the interactions between DNA and histone proteins, allowing other chromatin-remodeling factors to access the DNA.

This process enables the modulation of gene expression and various cellular processes such as DNA replication, repair, and transcription. DNA helicases are highly conserved across different organisms and are essential for maintaining genomic integrity and regulating DNA-based transactions.
