Answer:
<u>d. Skeletal muscle</u>
Explanation:
There are two components of efferent nervous system.
- <u>Somatic nervous system</u>
- <u>Autonomic nervous system</u>
<u>SOMATIC NERVOUS SYSTEM:</u>
Somatic nervous is one of the components of efferent/motor nervous system.
It controls <u>voluntary activities</u>. It involves the <u>control of skeletal muscles</u>.
It is composed of <u>the motor neuron and the innervating muscle</u>.
<u>AUTONOMIC NERVOUS SYSTEM:</u>
Autonomic nervous system is the other efferent/motor system of the body. It controls the <u>involuntary activities</u>. It involves the control of <u>cardiac muscle, glands and smooth muscles</u> of the body.
It is composed of<u> 2 neurons; preganglionic and postganglionic neurons.</u>
Autonomic nervous system is further divided into:
- Sympathetic nervous system (it is responsible for flight and fight responses)
- Parasympathetic Nervous system (it is responsible for rest and digestion)
- Enteric division ( controls Gastrointestinal system)
<u>QUESTION:</u>
<u>d. skeletal muscle</u>
This is the correct answer choice as skeletal muscles are not controlled by autonomic nervous system. They are controlled by somatic nervous system and are under voluntary control.
Answer:
The correct answer is desert.
Explanation:
If an entomologist wants to look for a good example of an organism that prevents water loss, he must look for organisms in the desert.
A desert is one of the ecosystems that <u>receives less water</u>, the rainwater that falls is<u> less than 150 mm per year.
</u>
Despite the heat and lack of water, there is a wide variety of living beings that inhabit this type of ecosystem. But for that <u>they must save water</u>, and they do this through adaptations that they developed when they were living in this place.
They can have two types of adaptations: physical or behavioral adaptations.
In behavioral adaptations, desert animals simply avoid the sun to generate greater water retention. Depending on the species, <u>some choose to go out only during the night</u>, and others <u>prefer to be under the shadow of a cactus.
</u>
Some species also get the water they need through the food they eat, which prevents them from having to go in search of water.
One type of physical adaptation is the one that occurs in those animals who accumulate fatty tissue in their body which allows them to <u>stay fresh and thus prevent water from evaporating.</u>
Answer: When DNA is being copied for the Daughter cells
Explanation: There is a mistake when the DNA is being copied for the new daughter cells. When a cell divides, it must divide its DNA into 2 exact copies of the orginal DNA for the 2 new daughter cells. Sometimes the copy isn't correct and the cells mutates.
hi i need a definition of adaptation, camouflage, habitat, hibernation, migration, mimicry, niche, predator, prey, reproduction,
gladu [14]
Answer:
species is a group of organisms of common ancestry able to reproduce only among. reproduction is Formation of new cells or a new individual. adaptation is A changing to fit new conditions. niche is ecology) the status of an organism within its environment and community (affecting its survival as a species). camouflage is camouflage. mimicry is Gaining protection by looking and acting like a different species. migration is Form of relocation diffusion involving permanent move to a new location. hibernation is A state of extremely low metabolism and respiration, accompanied by lower-than-normal body temperatures. predator is An animal that hunts other animals for food. prey is Animal hunted or caught for food. habitat is Place where an organism lives. organism is any living thing made up of one or more cells. invasive species is plants and animals that have migrated to places where they are not native. last non native species is not from an area, usually harmful.
