The stages of bee development are egg, larva, pupa, and adult. Eggs hatch into larvae, which then transform into pupae. Finally, adult bees emerge and undergo further maturation.

The stages of bee development are:

1. Egg: The bee life cycle begins when the queen bee lays an egg in a honeycomb cell.

2. Larva: The egg hatches into a larva, which is a legless, grub-like creature. The larva is fed a special diet called royal jelly, which stimulates its growth.

3. Pupa: The larva undergoes metamorphosis and transforms into a pupa. Inside the sealed cell, the pupa undergoes various changes, developing into an adult bee.

4. Adult Bee: After completing the pupal stage, the fully developed adult bee emerges from the cell. The bee then undergoes further maturation, such as its exoskeleton hardening, wings expanding, and adult coloration appearing.

It's important to note that there are three castes of bees: queen, worker, and drone. The development process for each caste is similar, but the diet and size of the cells they are raised in differ, leading to their distinct roles within the colony.

The correct option from the given question is option A) Freshwater is expected to decrease due to climate change.

Explanation:

Climate change refers to the long-term changes in the average weather patterns that have come to define Earth’s local, regional, and global climates. Climate change is primarily due to the increase in atmospheric concentrations of greenhouse gases (GHGs) produced by human activities, such as burning fossil fuels and deforestation.

Climate change has numerous consequences on the planet, including rising temperatures, sea level rise, increased frequency, and severity of extreme weather events, and changes in precipitation patterns, all of which have significant impacts on human societies and ecosystems.

Among the given options, freshwater is expected to decrease due to climate change. Climate change alters precipitation patterns, resulting in more frequent and severe droughts in some regions and increased flooding in others, resulting in water shortages. Higher temperatures and evaporation rates result in drier soils, which reduces water availability. These factors can reduce the amount of freshwater available for human consumption, agriculture, and other purposes.

Answer :the answer is D

Explanation:

Substance P is a neuropeptide that plays a significant role in the transmission and modulation of pain signals in the nervous system. It acts as a pain enhancer rather than a pain detractor.

When tissue damage or inflammation occurs, substance P is released by sensory neurons in the peripheral nervous system. It acts as a neurotransmitter and binds to specific receptors called neurokinin-1 receptors (NK-1 receptors) in the central nervous system and peripheral tissues. This binding triggers a cascade of events that amplify the pain signal and contribute to the perception of pain.

Substance P is involved in several processes related to pain:

1. Sensitization of pain receptors: Substance P increases the sensitivity of pain receptors, known as nociceptors, making them more responsive to painful stimuli. This sensitization can lead to an increased perception of pain.

2. Inflammation and immune response: Substance P promotes inflammation by inducing the release of histamine, cytokines, and other inflammatory mediators. It also attracts immune cells to the site of injury or inflammation, further contributing to the pain response.

3. Transmission of pain signals: Substance P is involved in transmitting pain signals from the peripheral nerves to the spinal cord and brain. It helps relay pain information to higher brain regions, contributing to the conscious experience of pain.

While substance P is primarily associated with pain, it also has other functions in the body. It is involved in regulating blood flow, neurogenic inflammation, mood regulation, stress responses, and gastrointestinal functions. However, its role as a pain enhancer is well-established and has been a focus of research in the field of pain management and pharmacology.

Explanation:

The effect of different coloured light waves on the growth of pea plants was to be observed by a botanist. The same number of seeds were put in three plants with the same type of pots and the same type of soil and every day, they were given the same amount of water. If one pot is placed in a dark windowless closet, the second is placed on the windowsill and the third is placed under a lamp with a green bulb. The variable factor, in this case, will be the colour of light.

Plants require light for the process of photosynthesis. In the process of photosynthesis, the light is trapped by the chlorophyll pigment present in the mesophyll cells of the leaves of the plants.

The light energy is trapped and converted into chemical energy. This is then used for the hydrolysis of water and the reduction of carbon dioxide. These processes then result in the formation of glucose.

Therefore, the plant that gets abundant sunlight on the windowsill will grow better than the plant placed under a lamp and the plant placed under the lamp will grow better than the pot placed in a dark closet.
