Explanation:

Answer: The correct option is A (Segmentation waves; food to move backward and forward; peristalsis; food to move along the tract distally).

Explanation:

Gastrointestinal motility is defined as the different activities carried out by the smooth muscles of the tract which Involves it's contraction and relaxation to bring about the movement of ingested food through the gut for absorbing nutrients, water,electrolytes and eliminating waste products. These movements can be divided into two namely:

--> Mixing Contractions: These contractions are also called the SEGMENTATION WAVES. When a portion of the small intestine becomes distended with chyme, stretching of the intestinal wall elicits localised concentric contraction spaced at interval along the intestine causing segmentation of the small intestine. These contraction causes the movement of chyme BACKWARD and FORWARD which allows greater mixing with the secretions of the intestines.

--> Propulsive Contractions: These contractions are also called peristaltic waves. Bands of muscles in the walls of the gastrointestinal tract contract and relax alternately to push each bolus of food downwards slowly. This process is known as PERISTALSIS. This occurs in all regions of the tract causing the movement of food towards the anus (distal direction).

Therefore, gastrointestinal motility includes Segmentation waves which causes food to move backward and forward, and peristalsis; which causes food to move along the tract distally.

1. Convention on Biological Diversity

2. Convention on International Trade in Endangered Species of Wild Fauna and Flora

3. Convention on Migratory Species

4. Ramsar Convention on Wetlands

5. Convention on the Conservation of Antarctic Marine Living Resources

The Convention on Biological Diversity is the most embracing of these conventions, as it provides the most comprehensive coverage of conservation related issues. Its focus is on the conservation of biodiversity, sustainable use of resources, and the fair and equitable sharing of benefits arising from the use of genetic resources. Additionally, it provides strategies and commitments to ensure that exploitation of living resources is done with sustainability and responsibility, bringing it into line with the principles and goals of ecological conservation.

Here the physical changes are seen in the burning candle, cooling candle, tearing paper, wet paper, salt, and water in the test tube, while the chemical reactions are involved in the burning of the paper and the mixing of the vinegar with soda.

The physical change is the change in form, such as when the candle is burned or cooled down, then the wax that is formed has the same properties as the candle, or the paper pieces after being torn have the same properties. Chemical changes involve the formation of new things, such as when paper is burnt, this produces ash with a different chemical nature, and when the vinegar and soda is mixed, it produces a different product.

Explanation: decomposers break down things

Answer:

Biodiversity or Biological diversity is a term that describes the variety of living beings on earth. It is described as degree of variation of life. Biological diversity encompasses microorganism, plants, animals and ecosystems such as coral reefs, forests, rainforests, deserts etc.

-In biodiversity, each species, no matter how big or small has an important role to play in ecosystem. It represents the wealth of biological resources available to us. It’s all about the sustaining the natural area made up of community of plants, animals, and other living things that is begin reduced at a steady rate as we plan human activities that is being reduced by habitat destruction.

Explanation:

A) The three levels of biodiversity are genetic diversity, species diversity, and ecosystem diversity.

B) Ecosystem services provided by biodiversity include pollination, pest control, and nutrient cycling.

A) The three levels of biodiversity are genetic diversity, species diversity, and ecosystem diversity. Genetic diversity refers to the variation in genes within a species, which allows populations to adapt and survive in changing environments. Concerns associated with the loss of genetic diversity include reduced adaptability to environmental changes and increased vulnerability to diseases.

Species diversity refers to the variety of different species within an ecosystem. Loss of species diversity can disrupt ecological balance, impact food webs, and lead to the extinction of keystone species. It can also result in the loss of potential sources for medicines, agricultural crops, and other valuable resources.

Ecosystem diversity refers to the variety of different ecosystems in a region. Loss of ecosystem diversity can result in habitat loss, fragmentation, and degradation, leading to the decline or loss of specialized species adapted to specific habitats. It can also impact the provision of ecosystem services, such as water purification, climate regulation, and nutrient cycling.

B) Species and genetic diversity provide several ecosystem services to humans. One example is pollination, where diverse species of pollinators, such as bees, butterflies, and birds, ensure the reproduction of flowering plants and agricultural crops. Another ecosystem service is pest control, where diverse predator species help regulate populations of agricultural pests.

Ecosystems also provide the service of nutrient cycling, where diverse decomposers, such as fungi and bacteria, break down organic matter and recycle nutrients back into the soil. This process is crucial for maintaining soil fertility and supporting plant growth. Lastly, diverse ecosystems contribute to climate regulation by absorbing and storing carbon dioxide, a greenhouse gas that contributes to climate change.

Overall, species and genetic diversity support the functioning and resilience of ecosystems, benefiting human well-being by providing essential services like pollination, pest control, nutrient cycling, and climate regulation. Protecting and conserving biodiversity is essential for maintaining these services and ensuring a sustainable future.

Explanation:

Your digestive system absorbs water and nutrients from the food you eat. Your circulatory system carries oxygen, water, and nutrients to cells throughout your body. Wastes from the cells are eliminated by your respiratory system, your excretory system, and your skin.

Water. Water is responsible for the formation of landforms like rivers, valleys, canyons, and deltas.

What are Landforms?

Landforms are natural features of the Earth's surface, such as valleys, mountains, plains, plateaus, hills, and coasts. They are formed by geological processes, such as erosion, volcanic activity, tectonic movements, and deposition. Landforms can vary in size from tiny ripples in the sand to large mountain ranges.

Wind can carry sediment and erode existing landforms, but it is water that is mainly responsible for the formation of landforms. Plants and animals can influence the formation of landforms, but not to the same extent as water.

Epithelial cells are tightly packed, and this lets them act as barriers to the movement of fluids and potentially harmful microbes. Often, the cells are joined by specialized junctions that hold them tightly together to reduce leaks.

Explanation:

Answer:

D. The allele frequencies will remain the same as they were in the parent population.

Explanation:

In population genetics, the Hardy-Weinberg equilibrium predicts that genotype and allele frequencies will remain constant from one generation to the next. The Hardy-Weinberg principle has five major assumptions: random mating, no mutation, no gene flow, infinite population size, and no selection. In a population, genetic change can be measured as a change in genotype frequencies or allele frequencies, but a type of change does not necessarily imply a change in the other. In this case, the frequency of alleles in the pool of male and female gametes (sperm and eggs, respectively) that meet to make the next generation will be the same, but genotype frequencies change from one generation to the next.
