Final answer:

The question is a riddle where 'born in 1995' refers to a hospital room number, rather than a year, while 'died in 1975' refers to the year. This type of question promotes critical thinking.

Explanation:

The question, "A scientist was born in 1995 and died in 1975. How is this possible?" is likely not based on historical fact but rather is a riddle or puzzle. The answer to the riddle is that the scientist was born in a hospital room with the number 1995 and died in the year 1975. This is a common type of brain teaser that uses the ambiguity of the English language to create a seemingly impossible situation. Such questions are generally used to encourage critical thinking and problem-solving among students.

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.

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.

Option-C

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:

Answer

Explanation:

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.

However, plants generally do not increase erosion; in fact, they often prevent erosion by stabilizing the soil with their root systems. Therefore, option B, Increase erosion, is the correct answer as it is not an environmental benefit of plants.

Answer:

Cellular respiration can occur both aerobically (using oxygen) and aerobically (without oxygen).

Explanation:

During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as by-products.

In cellular respiration, glucose and oxygen react to form ATP. As by-products, water and carbon dioxide are released.

In cellular respiration, glucose and oxygen react to form ATP. As by-products, water and carbon dioxide are released.

The three stages of aerobic cellular respiration are glycolysis (an anaerobic process), the Krebs cycle, and oxidative phosphorylation.

Answer:

has spores contained in ascus

Explanation:

Ascospores with honeycomb surface decoration may be seen under a microscope; each sac or ascus frequently contains two of these spherical spores. The correct answer is c) has spores contained in the ascus.

A fruiting fungus that is tasty is the black truffle. They are a favorite food in France and are highly well-liked there. In order to create some of the most beautiful gourmets, they are both grown and harvested from natural sources. They are one of the most valued products for commerce and are often gathered in the autumn.

Fungi, which include yeasts, molds, and mushrooms, are eukaryotic organisms that play a major role in environmental decomposition. Ascomycota is the phylum in which the flavorful edible fungus known as the black truffle resides. They are expensive and are often found in southern Europe. The ascus, a sexual spore-bearing cell containing ascospores, is the primary characteristic of the Ascomycota. Black truffles have a spherical form, a skin color of black-brown, and little cusps that resemble pyramids.

Numerous asci (spore-bearing cells) and tightly woven hyphae (a long filament-like structure) are present. Each ascus includes spores known as ascopores, which are unique to fungi included under the ascomycetes order. The phylum of Basidiomycota includes mushrooms. Additionally made of hyphae, they reproduce sexually by forming special cells called basidia, which produce spores known as basidiospores.

Therefore the correct answer is c).

Explanation:

Important observations for spider identification include a shiny black color, a red spot on the abdomen, eight legs, a plump abdomen, and a hard exoskeleton. A red spot, especially shaped like an hourglass, often indicates a black widow spider.

To identify a spider, certain observations are most helpful. Observations such as a shiny black color, a red spot on the abdomen, the presence of eight legs, a round plump abdomen, and a hard exoskeleton would all contribute significantly to spider identification. Notably, the red spot on the abdomen is distinctive of the black widow spider, which is known for its venom that can be toxic to humans. All spiders, as arachnids, possess certain characteristics such as eight legs, which distinguishes them from insects. Distinguishing features like leg length, hairiness, and relative size of body segments can assist in classifying spiders into groups.

Answer:

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.

The law of reflection applies to both flat and curved mirrors, stating that the angle of incidence equals the angle of reflection. Curved mirrors, such as convex and concave mirrors, reflect light in a way that alters the image size, orientation, and whether it's real or virtual. The size of the object does not change the laws of reflection, which can be confirmed through optical experiments.

The law of reflection states that the angle of incidence is equal to the angle of reflection, with the incident ray, the reflected ray, and the normal (the line perpendicular to the surface) all lying in the same plane. This law applies to both flat and curved surfaces such as mirrors. When considering a flat mirror, the law of reflection leads to virtual images which are the same size as the object. The image appears as far behind the mirror as the object is in front of it.

In the case of a convex or concave mirror, the reflection still obeys this fundamental law, but the curvature of the mirror causes the reflected rays to diverge or converge, which affects the characteristics of the image. The /size, orientation, and type (virtual or real) of the image can vary/ based on the distance of the object from the mirror and the focal point. For example, in a concave mirror, when an object is closer than the focal point, the image is virtual and enlarged; beyond the focal point but closer than twice the focal length, the image is real and inverted. When the object is further away than twice the focal length, the image is smaller and still inverted.

Regarding the question of whether the /size of the object changes the laws of reflection/, it does not. The laws remain constant, but the size of the object can affect the visibility and the extent of the reflected rays across the mirror's surface, particularly for curved mirrors. In optical experiments, using flashlights and mirrors, the law of reflection can be observed and confirmed, either with a plane mirror producing predictable reflection angles or with curved mirrors that focus light in specific ways, like in flashlights or concert shells.
