Explanation:

Desertification refers to the formation of barren land from the arid land due to many factors which could be climatic or anthropogenic. The climate factors include no rainfall, arid conditions, less water and water bodies, overgrazing by animals and many others.

As a result of these factors, the plants die or are unable to hold the soil. This leads to loosening of soil which causes soil erosion. This converts the fertile land into infertile land and the land becomes barren.

Thus, desertification is the correct answer.

Answer:

Explanation:

Cellular respiration is the metabolic process where cells convert glucose and oxygen into ATP, carbon dioxide, and water. ATP is the energy currency that cells use for their functions. This process is essential for transforming the energy stored in food into a usable form for cellular activities.

When you consume carbohydrates, they are broken down into simple sugars like glucose through digestion. This glucose enters your cells and undergoes a metabolic process known as cellular respiration. This process is crucial for converting the chemical energy stored in the glucose into a form that the cell can use, primarily in the form of adenosine triphosphate (ATP).

Cellular respiration occurs in three main stages: glycolysis, the citric acid cycle, and the electron transport chain. In glycolysis, glucose is split to form pyruvate, releasing a small amount of ATP. During the citric acid cycle, these pyruvate molecules are further broken down, releasing electrons, which are then used by the electron transport chain to generate a large amount of ATP. Overall, cellular respiration transforms glucose and oxygen into carbon dioxide and water, releasing energy captured in ATP molecules for cellular activities.

The products of cellular respiration are carbon dioxide, water, and ATP. The carbon dioxide produced is exhaled through the lungs, and the water may be used within the cell or excreted. The ATP generated provides energy for various functions within the cell, enabling life processes to continue.

Answer:

A

Explanation:

Answer:

Through transpiration and use of carbon dioxide (green house gas)

Explanation:

Plants help in making the climate stable in following two ways –  

a) Temperature offsetting – Plants take in carbon dioxide from atmosphere and thereby reduces atmospheric carbon. Due to reduction in greenhouse gases, the temperature reduces.  

b) Moisture regulation – Plants transpire through their leaves. Through transpiration, they release water as vapor and cool down the air. The higher the vegetation , the more is the transpiration.

Answer:

I think that the elevation of the bird will not change because the bird is flying and has not landed yet so it will not affect the elevation of the bird and it wont   affect the box's weight

Explanation:

The elevation of the hummingbird inside the closed box will not change when the box's elevation jolts slightly. This is due to the concept of inertia.

In this scenario, the elevation of the hummingbird inside the closed box will not change when the box's elevation jolts slightly. This is because of the concept of inertia, which states that an object at rest will stay at rest unless acted upon by an external force. Since the hummingbird is already hovering inside the closed box, it is not in direct contact with the walls of the box or any external force, so its elevation remains the same.

The air molecules inside the box might be affected by the jolt, they will exert pressure on the walls of the box which in turn will affect the box's movement. However, the hummingbird, being a separate entity, will not experience any change in its elevation.

It is important to note that when objects are contained within closed systems, their motion is independent of the motion of the container.

Symbiotic Mutualistic relationship

Explanation:

The bees get honey, and the flowers get to reproduce through their pollen being spread by the bees. Both parties benefit.

Answer:

Animal-like protists and plant-like protists are both eukaryotic and live in moist environments. All animal-like protists are heterotrophic and eat other organisms. Most plant-like protists are autotrophic. Some can be both autotrophic and heterotrophic, while a few are completely heterotrophic. All animal-like protists are unicellular, while plant-like protists can be unicellular, multicellular, or live in colonies. Most animal-like protists can move, while only some plant-like protists can move.

Explanation:

Plant-like protists and plants are both autotrophic, using photosynthesis, with examples such as algae. Protists differ from plants in their simpler structures and more variable life cycles. Protists play vital ecological roles as primary producers, decomposers, and sources of nutrition in food webs.

Plant-like protists and plants share the characteristic of being autotrophic, meaning they both use photosynthesis to convert sunlight into energy. An example of multicellular plant-like protists are algae, which also contain chloroplasts like plants. However, plant-like protists are different from true plants in that they do not have a complex structure of roots, stems, and leaves, and their life cycles can be more variable. Many of them are unicellular or form simple colonies.

Ecological Importance of Plant-like Protists

Plant-like protists play a critical role in their ecosystems, serving as primary producers and thus forming the base of the food web in aquatic environments. They are responsible for producing a significant portion of the world's oxygen, and they can also impact the carbon cycle through their photosynthetic activities.

Diversity among Protists

Protists are a diverse group of organisms that can be plant-like, fungus-like, or animal-like in nature. Fungus-like protists such as slime molds absorb nutrients from decaying matter, while animal-like protists may actively hunt or ingest their prey. Protists can also reproduce in a variety of ways and can include pathogenic species that cause diseases in humans and plants. Additionally, protists serve as an important food source and some are known as saprophytes, playing a role in the decomposition process.

Based on structural components, plant cells have a cell wall, chloroplasts, and a large central vacuole, making them distinct from animal cells, which lack these but contain centrioles and lysosomes. These differences are key in identifying the cell type.

Identifying whether cells are plant or animal cells involves comparing their structural components. From the given descriptions, we can differentiate these cells based on key features. Plant cells are characterized by the presence of a cell wall, chloroplasts for photosynthesis, plasmodesmata for cell communication, and a large central vacuole that maintains cell turgidity. Conversely, animal cells are notable for their lack of a cell wall, absence of chloroplasts, and instead contain centrioles and lysosomes.

Plant cells have distinct features that set them apart from animal cells. Plant cells possess organelles like chloroplasts for photosynthesis, a large central vacuole for storage, and a cell wall for structural support. On the other hand, animal cells lack these structures and have centrioles, lysosomes, and centrosomes.

The presence of a cell wall, chloroplasts, and a large central vacuole are characteristic features of plant cells, not found in animal cells. Such structures enable plants to perform photosynthesis, provide structural support and store nutrients, respectively. In contrast, animal cells have unique components like lysosomes for waste disposal and centrioles that play a role in cell division. These differences are critical for their distinct biological functions. Therefore, identifying these components is essential in distinguishing between plant and animal cells.

There are many factors that affect the respiratory rate: age, gender, size and weight, exercise, anxiety, pain, the effect of some medicines, smoking habits and excitement level are among them.

Explanation:

Breathing is a necessary function for human beings.  It supplies oxygen for a process called cellular respiration, which is how cells manufacture the energy they need for their life functions.  There are lots of things that can affect the rate of breathing in humans.  Exercise is one of those things, particularly aerobic exercise.  Aerobic exercise is any exercise that causes the person to breathe more, such as running, jogging, playing basketball, football, running track, or playing soccer.  Another factor that can influence breathing rate is allergic reactions to stimuli from the environment, such as pollen.  This can inflame the passageways leading to the lungs, making them smaller, requiring more air.  Smoking is a habit that can influence the development of lung cancer, which in turn influences the rate a person breathes.  Nervous conditions and reactions to stimuli also influence the breathing rate, such as the famed "fight or flight" syndrome.

Five factor that affect the rate of breathing are injuries, exercise, emotion, mood, and Lung elasticity.
