Answer:
Some particles went through vacant regions of the atom, while others were redirected by concentrated clusters of positive charge within the atoms.
Explanation:
In Rutherford's experiment, particles either passed straight through the gold foil or were deflected by the positively charged nucleus.
This response is accurate because the particles moved through vacant regions of the atom (not just spaces among atoms), with some being deflected by zones of concentrated positive charge (the nucleus).
Answer:
Ethylene. (Ans. D)
Explanation:
Ethylene controls the aging and ripening processes in plants. While many fruits and vegetables generate small amounts of ethylene, climacteric fruits like bananas produce larger quantities. This ethylene release accelerates respiration, triggers more ethylene production, and causes changes in color and flavor.
Therefore, when transporting green bananas over long distances to stores, the ethylene gas should be removed from their surrounding environment.
A body system is fundamentally made up of various organs and tissues that function collaboratively to facilitate a shared bodily process. The body systems consist of the following:
Circulatory system - involved in the blood circulation
Digestive system - responsible for food particle breakdown
Skeletal system - consists of bone structures that form our body's framework
Nervous system - comprises nerve cells that react to various stimuli
Respiratory system - manages the intake of oxygen and the expulsion of carbon dioxide.

Answer: The hormones secretin and cholecystokinin act on the pancreas, stomach, and gallbladder.
Explanation:
The duodenum produces two more hormones. Cholecystokinin (CCK), similar to enterogastrone, is released when fat is present in the chyme. CCK promotes the contraction of the gallbladder, which releases bile into the duodenum to help emulsify and digest fat more effectively. The other hormone from the duodenum is secretin. In response to the acidic chyme entering the duodenum, secretin triggers the pancreas to release bicarbonate, thereby neutralizing some of the acid.
