Answer:
Humans must decrease the harmful impact they have on earth or else the human population could go extinct forever. One way to do this is to inform the people on climate change and its effects. Recycling, using metal straws, carpooling, cleaning up beaches, pulling unncessary plugs in your house to reduce electricity usage, and doing so much more can help reduce the risk of climate change and help the world become a much healthier and stable place for humans, plants, animals, and the environment.
Explanation:
Answer: Option A) True
The statement is true
Explanation:
Impulses of motor neurons could inhibit the cells of the effector (e.g skeletal muscles, gland). Hence, the axons cause the release of glycine which inhibits or checks muscular contractions.
Answer:
a. Genetic variation may be lost from the species as a whole
d. The overall adaptive prospects of the species may decline.
Explanation:
Genetic variations are heritable traits possess by the offspring from it progenitors. This makes the offspring to be an hybrid species because it has inherited the traits of both of his/her parents. In a local population setting goes to extinct, it might be as a result of genetic variation because these inherited variations comes in several ways, some might be adaptability to thrive in adverse weather conditions, some production of specific hormones to combat the current state that its not suitable for them etc. so when a population shows a decline in genetic variation, such population is liable to extinction.
Also, when species can't cope with factors attached with adaptation to a particular ecosystem, (such as exhibiting camouflage in time of danger, during dry season when food scarcity has increased etc) there will be decline in population of the species.
