Answer is a. therapeutic communities.
Therapeutic communities are a common form of long-term residential treatment for substance use disorders. These communities provide drug-free environments in which people with addictive problems live together in an organized and structured manner to promote change toward recovery and re-socialization. Some such groups evolved into self-supporting and democratically run residences to support abstinence and recovery from drug use.
Answer:
Both C and E are reasonable answers.
Explanation:
Homeostasis describes the body's ability to maintain a stable equilibirum. In other words, if the body experiences a stress, it will generate a response that works to counteract that stress and restore itself to how it was prior to the stress.
A. This describes a cause and effect (BP down --> venous return down). It does not describe an active physiological response to counteract the BP drop such as an increase in heart rate. Not homeostasis.
B. Again, a cause and effect is described. Blood vessel walls becoming thinner is not a response to counteract increased BP. Not homeostasis.
C. Here a response to a stress is described. Men are drinking more water. The body responds by getting rid of that water, restoring the body to its former state. This describes homeostasis.
D. This sounds like homeostasis, but it's actually the opposite of what happens. Dilation of peripheral blood vessels is a way for the body to get rid of heat. This is the opposite of what you would want if the body got colder - it would make the stress worse, which is the opposite of homeostasis. In actuality the response to cold temperature is constriction of blood vessels to preserve heat.
E. This deescribes homeostasis. The stress is increased glucose. The body's response to manage it is to release insulin, which helps remove the glucose from circulation.
The appropriate response is cilia. Cilia are little hair-like structures on the surface of the cell. The hairs clear hair, bodily fluid, caught tidy and microscopic organisms up to the back of the throat where it can be gulped.
Cilia are found in the coating of the trachea (windpipe), where they clear bodily fluid and earth out of the lungs. In female well evolved creatures, the beating of cilia in the Fallopian tubes moves the ovum from the ovary to the uterus.
Answer:
Explanation:
Active transport is the movement of molecules or substance from a region of lower concentration to a region of higher concentration across a cell membrane against the concentration gradient.
Active transport requires cellular energy and are of two types:
primary active transport that uses adenosine triphosphate (ATP), and secondary active transport that uses an electrochemical gradient.
Active transport helps in the uptake of glucose in the intestines.
Cotransport or secondary active transport is the movement of molecules across a membrane it uses electrochemical potential difference that is created by pumping ions in or out of the cell.
Cotransport helps in the transport of glucose across the cell membrane.
I think B. Fruits develop from ovary walls... I think this because it does not accurately describe fruits.
Hope this helps!
