Explanation:
A slow, continuous process is defined as gradualism that occurs at slow rate but at a steady pace.
For example, stripes of a tiger develop slowly and at a steady pace so that they can hide in tall grass represents gradualism.
Whereas punctuated equilibrium is a process in which there is sudden and frequent changes that results in the formation of new species.
For example, species living in a sea for thousand of years breed and die over there and suddenly when there is change in sea level than animals must adapt represents punctuated equilibrium.
Sour receptors occur primarily along the sides of the tongue and are stimulated mainly by acids. Salt receptors are most common in the tip and upper front portion of the tongue. They are stimulated mainly by inorganic salts. Bitter receptors are located toward the back of the tongue
hopefully this helps but i could be really wrong lol
A - Endoplasmic Reticulum.
Answer:
B. Base pairing occurs within an RNA molecule to give RNA the three-dimensional shape needed for specific functions.
Explanation:
Ribonucleic acid, known as RNA, is a type of nucleic acid found in living systems. In opposition to the other type of nucleic acid (DNA), RNA is a short single stranded molecule. Both DNA and RNA are made of nucleotides, composed of a phosphate group, nitrogenous bases and a pentose sugar.
The presence of ribose sugar and Uracil base in RNA instead of deoxyribose sugar and thymine base respectively structurally differentiates the molecule from DNA. However, base pairing occurs within the RNA molecule to form the three-dimensional shape of the RNA, which is key to the specificity of its function.
Answer:
1 - natural selection
2 - uniformitarianism
3- inheritance of acquired characteristics
4 - catastrophism
Explanation:
1. Natural selection refers to the evolution of organism or changes in the characterstics of organism depending on the environmental conditions. Hence, the lizard moved on fantasy island evolved with larger head and stronger bites as per the environmental condition.
2. The concept of Uniformitarianism states that the natural geological processes happening in present have already occured in past with same intesity and rate. Hence, geologist uses the phrase "The present is the key to the past" for formation of mountain, rock formation and water movements.
3. Inheritance of acquired characteristics are the characteristic acquird by the ancestors and transmitted that gradually acquired characteristic to their progeny. Hence, the rats acquire the charactieristics and transfered it to the next generations.
4. Catastrophism means the regular occurrence of meteorological and geological disturbances to explain the existence the fossil record. Hence, teh mass exticiton due to asteroid impact is an example of Catastrophism.
So, the correct options in sequential order is natural selection, uniformitarianism, inheritance of acquired characteristics, and catastrophism.
