Seeds grow with the help of various natural resources like water, oxygen, and sunlight, which help them to sprout and grow roots and develop into new plants. Some seeds grow as soon as they land in the ground, while others need a specific time period to grow.

The life of a plant begins with a seed that contains the necessary resources required for the plant's growth, which includes the embryo, endosperm, and protective seed coat.

The process through which plants grow, reproduce, and die is called their life cycle. It includes different stages like germination, growth, flowering, pollination, fertilization, seed production, and dispersal.

Seeds need water, food, and a little heat to grow into new plants. Water helps seeds to soften and expand, and food helps them to provide the necessary nutrients required for growth. The heat helps seeds to break dormancy and activate enzymes that speed up the germination process.

A new plant has the same life cycle as its parent plant. Plants have a unique life cycle, and every stage of the life cycle is essential for their growth and development. New plants inherit their genetic traits from their parent plants, and their life cycle is the same as that of their parent plant.

New plants that grow from seeds inherit their genetic traits from their parent plants and have the same life cycle as their parent plants. The life cycle of a plant includes the stages of germination, growth, flowering, pollination, fertilization, seed production, and dispersal. Thus, new plants that grow from seeds are like their parent plants.

The correct order of steps for a broth to agar plate transfer is:

Sterilize the inoculating loop prior to replacing it in the loop holder.

Sterilize the loop again, remove the cap of the culture tube, and pass the mouth of the culture tube through the Bunsen burner flame.

Remove a loopful of bacterial culture from the broth tube, pass the mouth of the tube through the Bunsen burner flame, and replace the cap.

Lift the lid of the agar plate slightly and streak the loop across the surface of the agar plate.

Replace the lid.

Sterilize the loop, transfer culture, and streak agar.

To transfer bacterial culture from a liquid broth to an agar plate, it is important to maintain aseptic technique to prevent contamination. The process involves sterilizing the inoculating loop prior to use by passing it through a flame. The culture tube's cap is removed, and the mouth of the tube is passed through the Bunsen burner flame to eliminate potential contaminants.

A loopful of the bacterial culture is then taken from the broth tube and the tube is promptly recapped. The lid of the agar plate is lifted slightly, and the loop is streaked across the surface of the agar to evenly distribute the culture. Finally, the plate's lid is replaced to maintain sterility.

This method allows for the growth of individual bacterial colonies on the agar plate, facilitating further analysis and experimentation.

Answer:

the water is solid at 5c and liquid at 45 c

Explanation:

One of the most common adaptations is the ability to conserve water.

What adaptations do hot deserts have?

Hot deserts have a range of adaptations that help organisms survive in the harsh, arid environment.

Water conservation: Hot deserts have little water, so organisms have developed ways to conserve water.

Heat tolerance: Hot deserts have extreme temperatures, so many organisms have adaptations that allow them to tolerate high temperatures.

Nocturnal behavior: Many animals in hot deserts are nocturnal, meaning they are active at night and rest during the day when temperatures are highest. This helps them conserve energy and avoid heat stress.

There are several adaptations that organisms may develop in response to high temperatures found in the desert.  Since water is scarce in the desert, organisms that live there must be able to retain as much water as possible. For example, some desert animals have developed the ability to excrete concentrated urine, and some desert plants have developed the ability to store water in their tissues.

Therefore, ability to conserve water is the most common adaptations.

Biodiversity includes genetic, species, and ecosystem diversity, and is vital for ecosystem functioning, economic value, and cultural significance. Threats include habitat loss, climate change, pollution, overexploitation, and invasive species, necessitating conservation efforts.

1. Biodiversity refers to the variety of life on Earth, encompassing the diversity of species, ecosystems, and genetic variation within species. The three components of biodiversity are:

1. Genetic Biodiversity: It represents the diversity of genes within a species, including variations and traits that allow populations to adapt to changing environments.

2. Species Biodiversity: It refers to the variety of species in a particular area or globally. It includes the diversity of plants, animals, microorganisms, and other organisms, each playing a unique role in ecosystems.

3. Ecosystem Biodiversity: It encompasses the diversity of ecosystems and habitats on Earth. This component includes terrestrial, aquatic, and marine ecosystems, such as forests, grasslands, coral reefs, and wetlands, with their distinct biological communities.

2. Biodiversity is important for several reasons:

1. Ecosystem Functioning: Biodiversity is essential for the functioning of ecosystems. It supports ecological processes like nutrient cycling, pollination, soil formation, water purification, and pest control, which are vital for maintaining healthy and productive environments.

2. Stability and Resilience: Biodiversity enhances the stability and resilience of ecosystems. Diverse ecosystems are better able to withstand and recover from disturbances like climate change, natural disasters, and the spread of diseases.

3. Economic Value: Biodiversity contributes to economic prosperity through ecosystem services like food production, timber, medicines, tourism, and recreational activities. Many industries rely on biodiversity for resources and economic opportunities.

4. Climate Regulation: Biodiversity plays a crucial role in regulating the climate. Forests, for example, sequester carbon dioxide, a greenhouse gas, helping to mitigate climate change. Healthy ecosystems can also buffer against extreme weather events and contribute to local climate regulation.

5. Cultural and Aesthetic Importance: Biodiversity has significant cultural and aesthetic value. It is intertwined with cultural practices, traditions, and spiritual beliefs of diverse communities. Additionally, diverse natural landscapes and wildlife contribute to the beauty of our planet, inspiring art, recreation, and spiritual connections.

3. Common threats to biodiversity include:

1. Habitat Loss and Fragmentation: Destruction, degradation, and fragmentation of natural habitats due to activities like deforestation, urbanization, and conversion of land for agriculture, leading to the loss of species and disruption of ecosystems.

2. Climate Change: Alterations in global and regional climate patterns, resulting from human-induced greenhouse gas emissions, impact ecosystems and species' distributions. Climate change can lead to habitat shifts, altered species interactions, and increased extinction risks.

3. Pollution: Pollution from various sources, including industrial activities, agriculture, mining, and improper waste disposal, contaminates ecosystems, air, water, and soil, affecting the health and survival of species.

4. Overexploitation of Resources: Unsustainable hunting, fishing, logging, and harvesting of species and resources can deplete populations, disrupt ecosystems, and cause species declines or extinctions.

5. Invasive Species: The introduction of non-native species into ecosystems can outcompete native species, disrupt food chains, alter habitats, and drive native species to extinction.

Addressing these threats and conserving biodiversity requires collective efforts, sustainable practices, protected areas, conservation initiatives, and policy interventions to ensure the long-term survival of species and the functioning of ecosystems.

The correct option is (c)New inorganic and organic substances are created from energy in the process that occurs in the cells of both self-feeders and other-feeders.

Autotrophs (self-feeders) are organisms that synthesize the biological molecules necessary for life support and digest inorganic substances from their environment using an external energy source. This kind of nutrition is found in plants that prepare their food through photosynthesis.

An organism that consumes other species in a food chain is known as a heterotroph (other-feeders). Heterotrophs cannot transform inorganic materials into organic ones, in contrast to autotrophs. They have to rely on a source of organic carbon that was once a part of a living thing. Heterotrophs depend on autotrophs either directly or indirectly for nutrients and food energy. This kind of nourishment is present in parasites, bacteria, fungi, yeast, humans, and other animals.
