Answer:

No-till farming

B. No-till farming is associated with sustainable farming.

No-till farming is a farming method where the soil is not disturbed or tilled, but rather the crop residues are left on the surface of the soil. This helps to reduce soil erosion and improve soil health, and also helps to sequester carbon in the soil, which can help to mitigate climate change.

Other sustainable farming practices include crop rotation, agroforestry, and integrated pest management, all of which prioritize the long-term health of the soil, the ecosystem, and the community over short-term profits.

In contrast, intensive farming involves high-input and high-output agricultural practices that prioritize maximizing production and yield, often at the expense of environmental and social sustainability.

This type of farming may use excessive amounts of synthetic fertilizers and pesticides, which can harm the environment and potentially pose health risks to humans and animals.

Monoculture, or the practice of growing a single crop in a large area of land, is another unsustainable farming practice. This practice can lead to soil depletion, increased pest and disease pressure, and reduced biodiversity, which can ultimately lead to decreased productivity and long-term negative impacts on the environment.

Answer:

In these cases, genetic drift can result in the loss of rare alleles and decrease the gene pool. Genetic drift can cause a new population to be generally distinct from it's original population, which has led to the hypothesis that genetic drift plays a role in the evolution of new species.

a) Variation: Darwin - Random mutations; Lamarck - Acquired traits.

b) Individual Variation: Darwin - Natural variation; Lamarck - Acquired traits.

c) Change and Evolution: Darwin - Populations change; Lamarck - Individuals change.

d) Evolutionary Progress: Darwin - Adaptation, not perfection; Lamarck - Progressive improvement.

a) Darwin's theory of natural selection explains that variation within a population arises from random mutations and genetic recombination. Lamarck's hypothesis, in contrast, suggests that variation comes from acquired traits influenced by the environment and an organism's needs.

b) According to Darwin, individuals within a population exhibit natural variation, meaning they differ from each other in their traits. Lamarck's hypothesis implies that individuals are not inherently variable but can acquire and pass on acquired traits during their lifetime.

c) Darwin's theory states that individuals themselves do not change or evolve within their lifetime. Instead, populations change over time through natural selection, with individuals possessing different traits. Lamarck's hypothesis suggests that individuals can change and acquire new traits during their lifetime, which can then be inherited by their offspring.

d) Darwin's theory rejects the idea of evolutionary progress towards perfection. It emphasizes that evolution is driven by adaptation to the environment, with populations evolving in response to changing conditions. In contrast, Lamarck's hypothesis implies that evolution is progressive, with organisms becoming more complex and better adapted over time.

Answer:

Lipids are large molecules made from smaller units of fatty acids and glycerol.

The gas exchange that occurs in the alveoli capillary membrane is referred to as pulmonary respiration.

Pulmonary respiration is a process that involves the exchange of gases in the lungs. The process of pulmonary respiration can be broken down into three main stages: ventilation, gas exchange, and cellular respiration.

Pulmonary respiration involves the lungs, where oxygen is taken in and carbon dioxide is removed from the body. This type of respiration occurs in the alveoli capillary membrane, where gas exchange takes place.

During the gas exchange, oxygen moves from the air in the alveoli into the capillaries surrounding the alveoli, while carbon dioxide moves from the capillaries into the alveoli.

After the oxygen is transported into the capillaries, it binds with hemoglobin in red blood cells and is transported throughout the body to be used in cellular respiration.

During cellular respiration, glucose is broken down in the presence of oxygen to produce energy in the form of ATP. The carbon dioxide produced during cellular respiration is then transported back to the lungs to be exhaled.

In conclusion, the gas exchange that occurs in the alveoli capillary membrane is referred to as pulmonary respiration, which is an important process for breathing and providing oxygen to the body.

The graph is showing how primary production decreases as deep increases. It is due to the amount of available light in the water.

The primary production in the ocean is performed by microorganisms known as phytoplankton.

Phytoplankton populations are primary producers that include bacteria and algae, which use photosynthesis to produce biomass and release oxygen.

In a similar manner to plants, phytoplankton communities also contain chlorophyll in order to convert sunlight into biomass.

Preserving the DNA of the Tasmanian devils that show partial resistance to the devil facial tumor disease would fall under the level of genetic diversity.                                                                                                                                                  

Genetic diversity refers to the variation of genes within a population or species. By breeding these resistant individuals and preserving their DNA, researchers can increase the genetic diversity of the population and potentially develop a population of Tasmanian devils that are resistant to the disease. This is important because the devil population has decreased by 70% since 1996 due to the disease, and preserving genetic diversity can help ensure the survival of the species.

"Elimination of breeding places" is the most effective measure for mosquito control.

Option (a) is correct.

Mosquitoes require standing water to lay their eggs and for the larvae to develop. By removing or treating sources of standing water, such as stagnant ponds, gutters, or containers that hold water, mosquito populations can be greatly reduced.

Trapping of adult insects and the use of insecticides and repellents can also be effective measures for mosquito control, but they are not as effective as eliminating breeding places. Traps and insecticides can kill adult mosquitoes, but they do not prevent new mosquitoes from hatching and breeding. Repellents can help keep mosquitoes away from people, but they do not eliminate mosquitoes from an area.

Therefore, the most effective and sustainable approach to mosquito control is to eliminate or treat standing water to prevent mosquito breeding.
