Cat (Australia); lots of cats became feral and they reproduce very fast. They became the apex predator and the native species have no defense system for them, so the cats brought tens of species on the verge of extinction (mainly placental mammals).
Fox (Australia); became an apex predator in the lack of competition, and damages the populations of native small placental mammals.
Hair (Australia); reproduces much quicker than the native species of mammals, increased significantly in numbers, and out competes the native species for the food sources.
African bee (the Americas); much more aggressive and stronger than the native bees and systematically kills their populations.
Grey squirrel (Britain); reproduces quicker than the red squirrel, is bigger, and out competes for food, brought it on the verge of extinction.
Answer:
Lack of food sources, the lack of habitat, competition and evolving ways to compete.
Explanation:
Lack of food sources, the lack of habitat, competition and evolving ways to compete are the ecological conditions that is responsible for the rapid diversity of some lineages. With the passage of time, changes occurs in the lineages due to climate change which causes some species to extinct and some to evolve which attains adaptability to the environment. Due to climate change food is unavailable to the organisms which is the main cause of its extinction.
Answer:
55 degrees as an acute angle
Explanation:
There is the kelvin scale (unit is degree kelvin) the celsius scale(unit is degree celsius) and the farenheit scale (unit is degrees farenheit)
Answer:
The description regarding the central nervous system(CNS) control of the Autonomic nervous system (ANS) is correctly matched below.
Explanation:
The central nervous system(CNS) is composed of the brain (which consists of the hypothalamus, brainstem and cerebral cortex) and the spinal cord. The rest of the nervous tissues that is found throughout the body make up the peripheral nervous system which is further divided into somatic nervous system and autonomic nervous system (ANS).
Below is parts of the Central Nervous System(CNS) with the correct description of how it controls the autonomic nervous system (ANS):
1. Cerebral Cortex: This is the part of
--> Emotions can invoke autonomic responses
--> sexual thoughts or images can increase blood flow to the genitals.
2. Hypothalamus:
--> It activates the fight-or-flight response
--> it's the major control center of the ANS. it's the integrating center for thermoregulation
3. Brainstem:
--> it's the integrating centers for reflexes controlling heart rate and blood pressure
--> it's the integrating center for the pupillary reflex.
4. Spinal Cord:
--> it's the integrating center for urination, defecation, erection, and ejaculation reflexes.
