Answer:

The answer is A. provides the energy for adding a phosphate to ADP to make ATP.

Explanation:

The ATP synthase is an enzyme located in the inner membrane of the mitochondria. It creates a hydrophilic channel across the inner mitochondrial membrane that allows a flux of protons that moves down an electrochemical gradient. These H+ ions are then used as an energy source during the enzymatic reaction that converts ADP + Pi to ATP. This process is called chemiosmois and it’s not unique to cellular respiration, it is also used in photosynthesis and other processes involved in homeostasis. The proton-motive force, as some people refer to the proton gradient was first proposed by Peter Mitchel in the 1960’s as the chemiosmotic theory.

After learning about several of the body systems, Jon tells the class that the digestive system and respiratory system have one

Valentin [98]

The correct answer is option D, that is, Jon is correct because the respiratory system removes waste from the body by ridding it of carbon dioxide when we exhale, and the digestive system removes waste from the body in the large intestine where the waste is sent and removed through the rectum.

The respiratory system functions to provide adequate oxygen for the proper functioning of the body and at the same time works to remove the waste products like carbon dioxide via the process of exhalation.

On the other hand, the function of the digestive system is digestion and absorption. It digests the food components into smaller pieces, and helps in the absorption of nutrients from the food, the leftover undigested food, or waste is excreted out through the rectum. Hence, both respiratory and digestive system exhibits one common function of excretion of waste materials.

Choose THREE examples that correctly predict the effect of a change on the ecosystem.

topjm [15]

Answer:

The answer is option A "A decrease in the kangaroo rat population will cause a decrease in the coyote population"

Explanation:

Climate is a significant ecological impact on environments. Changing Climate influences biological systems in an variety of ways. For example, warming may constrain species to relocate to higher scopes or higher rises where temperatures are more helpful for their endurance.

Environmental change not just influences biological systems and species straightforwardly, it likewise communicates with other human stressors, for example, advancement. Although a few stressors cause just minor effects when acting alone, their combined effect may prompt emotional natural changes. For example, environmental change may worsen the pressure that land improvement puts on delicate water front zones. Also, as of late logged forested zones may get defenseless against disintegration if environmental change prompts increments in substantial down pour storms.
