The distance used to determine the work is less.

When an external force drives an object a specific distance, it transfers a certain amount of energy to the object, which is known as work. The amount of work performed on an object is a measure of the energy transmitted to it. Work is defined as the sum of the force component acting in the displacement direction and the displacement magnitude (d).

A measurement of the energy that is transferred when an object is moved over a distance by an external force, at least some of which is applied in the direction of the displacement.

The output of a force is calculated by multiplying its component acting in the displacement's direction by its magnitude.

Answer:

glycolysis

Explanation:

glycolysis is the first way involved in cellular respiration.

The correct option is B. Fatty acids that are broken down for energy production are utilized for which aspect of cellular respiration is glycolysis.

Through a sequence of processes known as glycolysis, glucose is divided into two pyruvate molecules, each of which has three carbons. Since the majority of species alive today still use glycolysis, it is an old metabolic route that developed long ago.

Glycolysis is the initial step in the process of cellular respiration in organisms. However, many anaerobic organisms—organisms that do not use oxygen—also contain this route since glycolysis does not require oxygen.

Therefore, The correct option is B. Fatty acids that are broken down for energy production are utilized for which aspect of cellular respiration is glycolysis.

Materials move down a concentration gradient  is called a concentration gradient and the methods cells use to materials with out expanding energy is called Passive transport.

Passive transport tells  more about the shifting of substances down a concentration gradient and does not need any issue of energy consumption.

A concentration gradient is simply a stretch of space across which a substance's concentration alters. Substances will naturally travel down concentration gradients, from a higher concentration point  to a place or area that is known to be lower concentration area.

Therefore, substance diffuses over a membrane through passive transport as it diffuses along its concentration gradient without requiring any energy from the cell.

Fungi, actinomycetes, lichens, earthworms and plants are the bioindicators of body of water or an ecosystem.

Use of ecosystem or water bioindicators yields the following image.

Bioindicators are used to evaluate the state of the environment and how it changes over time. They include biological processes, species, or communities.

Lichens are one type of bioindicator. These plants are extremely vulnerable to airborne since they grow on surfaces like dirt, rocks, and trees. This is so that they may get the majority of their nutrition from the air.

The quantity and variety of lichens on the trees in our forests are indicators of how clean the air is. Because different lichen species are more or less susceptible to air pollution, knowing which species are present can also give us an idea of the pollution level.

Answer:

a is the correct answer Human uses of wetlands, such as drainage for agriculture and filling for industrial or residential development, can impose irreversible impacts to wetlands.

The human activity that would decrease the biodiversity of a wetland is adding a drainage system. The correct option is 1.

Biodiversity refers to the diversity of life on Earth, which includes species diversity, genetic diversity, and ecosystem diversity.

It is critical for ecosystem health and function, as well as the services they provide, such as air and water purification, nutrient cycling, and climate regulation. Biodiversity has cultural, recreational, and economic significance.

The extinction of species, the loss of genetic resources, and disruptions to ecosystem services are all examples of how biodiversity loss can harm ecosystems and human well-being.

Adding a drainage system would reduce a wetland's biodiversity by altering the natural water flow and affecting the habitat of various species, resulting in a decrease in their population and diversity.

Thus, the correct option is 1.
