Answer: d. a species is in stable and favorable environments.
Explanation:
Asexual reproduction is a mode of reproduction which can be seen in the simple organisms. A single organism give birth to many offsprings. This process does not requires mates and gamete formation. The sexual mode of reproduction involves two parents of opposite sex. This process requires gamete formation. When the gametes of opposite sex fuse together they form a zygote which is a precursor of new offspring.
Asexual reproduction results in greater reproductive success than sexual reproduction as this process does not require mates to give birth to the offsprings. But the asexually reproducing organisms requires stable and favorable environments for production of large number of offsprings. If the external environmental conditions are unfavorable the organism will not survive and reproduce. Thus the reproductive success will decline.
Explanation:
The factors that affects the rate of chemical reactions are;
- Nature of reactants
- Concentration of reactants or pressure
- Temperature
- Presence of catalyst
- Sunlight
In our body, the nature of reactants is very important. A food substance in solid form undergoes slow digestive process because it has little surface area exposure for the action of digestive chemicals. Most solid food are usually chewed in the mouth before digesting them to increase their surface area.
The increasing order of food digestion is;
lumps to granules to powder and to liquids.
Rotation is the motion that causes us to see phases
Answer: Active transport powered by adenosine triphosphate.
