Which effect does deforestation have on the carbon cycle?

Answers

Answer:

Deforestation facilitates one part of the carbon cycle, increasing the CO2 in the atmosphere. It also prevents forests from absorbing any further carbon by destroying the trees. It, therefore, inhibits this aspect of the cycle and leads to increased levels of this greenhouse gas in the atmosphere.

What is meant by wildlife? How is wildlife important for us?​

Answers

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.

What is the relationship between the curve seen in the graph and the environmental health of the oceans?
An increased population will result in the improved environmental health of the oceans due to more scientists inventing better technologies.
An increased human population size means that the ocean's resources will be used more efficiently.
As the population goes up, the oceans are more likely to be used as a habitat for humans.
As the population increases, more demands are put on the ocean to support human life.

Answers

Answer:

As the population increases, more demands are put on the ocean to support human life.

Explanation:

Many countries rely on the ocean for transport and as food sources. Over fishing has continuously been a growing problem as more and more fish are required to sustain populations as well as support more gourmet markets. A higher population will also lead to higher trade rates as more materials that aren't available in one country will need to be imported from others.

environment.

Answers

Answer:

For example, in the food chain, plants move carbon from the atmosphere into the biosphere through photosynthesis. They use energy from the sun to chemically combine carbon dioxide with hydrogen and oxygen from water to create sugar molecules.

Describe: Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants get rid of carbon dioxide gas through a process called respiration. Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement. Organisms play an important role in the carbon cycle in the following ways: Plants absorb carbon from the environment in photosynthesis and return it in respiration. Animals obtain their carbon by eating plants; they release carbon in respiration.

·Why does it make sense that blood flow varies throughout different organs

Answers

It is important that blood flow varies throughout different organs because of differences in the metabolic activities of the different organs.

What is the circulatory system?

The circulatory system refers to the system of organs and tissues which are involved in the circulation of blood around the body.

The circulatory system performs the essential function of delivering nutrients to tissues and cells as well as removing metabolic waste from them.

Since the different organs in the body perform specialized functions, some organs are actively involved in metabolic activities, therefore need greater blood flow.

Therefore, blood flow varies throughout different organs because of differences in their metabolic activities.

Which of the following results when homologous chromosomes cross over in meiosis?
Two sister chromatids get tangled, resulting in one re-sequencing its DNA.
DNA repair machinery alters maternal alleles so they match paternal ones
Two sister chromatids exchange identical pieces of DNA.
Corresponding segments of non-sister chromatids are exchanged.

Answers

When homologous chromosomes cross over in the process of meiosis, the corresponding segments of the non-sister chromatids are exchanged. Thus, the correct option is D.

What is Crossing over?

Meiosis is the process of cell division in which the chromosomal content of the cell reduces to half. This division is also known as reductional division. Meiosis is divided into two parts: Meiosis I and Meiosis II.

Meiosis I is divided into four phases which are Prophase I, Metaphase I, Anaphase I, and Telophase I. Prophase I is further divided into five stages which are Leptotene, Zygotene, Pachytene, Diplotene, and Diakinesis. Crossing over of chromosomes takes place during pachytene stage.

Crossing over or the chromosomal crossover is the exchange of the genetic material during the process of sexual reproduction between the two homologous chromosomes' non-sister chromatids which results into the formation of recombinant chromosomes.

Therefore, the correct option is D.
