Answer:
Species richness.
Explanation:
A common term, for organism populations.
As plants diverged from a common ancestor, characteristic features evolved that distinguished
the main plant groups from one another. Which statement shows the evolutionary sequence in
which these features developed?
A. vascular tissue, seeds, flowers
B. seeds, vascular tissue, flowers
C. flowers, seeds, vascular tissue
The statement 'vascular tissue, seeds, flowers' shows the evolutionary sequence in which plant features developed (Option A).
What is evolution?Evolution means descendence with modification, which mainly occurs due to natural selection.
In terrestrial plants, the main evolutionary feature that emerged was the appearance of vascular tissues.
Subsequently, terrestrial plants evolved to produce seed plants and then flowers (angiosperm plants).

What is the difference between B-cell lymphocytes and T-cell lymphocytes?
B cells regulate blood pH, and T cells regulate body temperature.
B cells are produced in the thymus, and T cells are produced in the bone marrow.
B cells engulf bacteria, and T cells carry bacteria to the lymph nodes.
B cells produce antibodies, and T cells destroy infected cells.
Answer:
B cells and T cells are the white blood cells of the immune system that are responsible for adaptive immune response in an organism. Both the cells are made in the bone marrow.Explanation:
B cells produce antibodies, and T cells destroy infected cells. So, the correct option is D.
What are B cells and T cells?The two primary categories of lymphocytes are T cells and B cells. Antibody molecules made by B cells can attach to and kill invasive viruses and bacteria. T cells are the immune system's first line of defence against foreign invaders. They also create cytokines, that are biological agents that aid in the activation of other immune system components.
T cells can eliminate malignant or contaminated cells. Moreover, they control overall immune response by assisting B cells in eradicating foreign infections. Antibodies are made by B cells. An antibody is a class of protein produced by B lymphocytes, sometimes known as B cells.
Therefore, the correct option is D.

What is meant by wildlife? How is wildlife important for us?
Answer:
Animals that grow or live in the wild without any human interference are known as wildlife. Importance of wildlife is as follows: Wildlife helps keep the food chain in place and thereby maintain ecological stability.
Explanation:
The term "wildlife" refers to all living organisms that exist in their natural habitat, without any human interference. It includes animals, birds, plants, and other organisms that thrive in forests, oceans, deserts, and other natural environments.
Wildlife is important to us in several ways:
1. Biodiversity: Wildlife plays a crucial role in maintaining biodiversity. Each species contributes to the intricate web of life, and the loss of even one species can have a significant impact on the entire ecosystem. For example, bees play a vital role in pollination, which is essential for the reproduction of many plant species.
2. Environmental balance: Wildlife helps to maintain a balance in ecosystems. Predators, such as lions or wolves, help control the population of herbivores, preventing overgrazing and maintaining the health of vegetation. This balance ensures that resources are distributed appropriately and prevents the dominance of a single species.
3. Ecosystem services: Wildlife provides various ecosystem services that benefit humans. Forests, for instance, serve as a habitat for countless species, help regulate climate, filter air and water, and provide resources like timber and medicinal plants. Wetlands act as natural filters, purifying water and reducing the risk of floods.
4. Cultural and recreational value: Wildlife also holds significant cultural and recreational value. Many communities have strong cultural connections to specific wildlife species, and these species may play important roles in their traditions, rituals, and beliefs. Additionally, observing and interacting with wildlife through activities such as bird-watching or safaris can bring joy and a sense of connection to nature.
5. Scientific and educational purposes: Studying wildlife helps us gain knowledge about different species, their behavior, and their roles within ecosystems. This understanding is crucial for conservation efforts and managing natural resources sustainably. Wildlife education also fosters a sense of environmental awareness and encourages people to become responsible stewards of the planet.
Hence, wildlife encompasses the diverse range of organisms found in their natural habitats. Its importance lies in its contribution to biodiversity, environmental balance, ecosystem services, cultural value, recreational opportunities, and scientific knowledge. Preserving and protecting wildlife is essential for the well-being of both the natural world and human society.

How does photosynthesis contribute to the organism’s energy needs
Answer:
Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy used to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as cellular respiration.

Which organism will most likely become fossilized from being buried in sediment? Insect , snail, jellyfish or a worm
Answer:
When an organism is buried quickly, there is less decay and the better the chance for it to be preserved. The hard parts of organisms, such as bones, shells, and teeth have a better chance of becoming fossils than do softer parts. One reason for this is that scavengers generally do not eat these parts.
