Answer:
(A) Protein-coding genes make up far less of the human genome than noncoding DNA.
Explanation:
The human genome contains both protein-coding and non-coding sequences. However, the non-coding sequences make most of the human genome as they account for as much as 98.5% of the total human genome. The non-coding part of the human genome serves other important functions such as promoter, enhancers, silencers for gene expression.
An only small part of the human genome serves as protein-coding genes and make exons.
The solutions, which have both hydrogen and hydroxide ions in equal number are neutral solution.
In a solution, if the hydrogen and the hydroxide ion are in equal number, they will mask each other's effect. So, all over, the effect of the hydrogen ion or hydroxide ion would be absent. So, the solution would indicate a pH of value 7.
Hence, the given blank can be filled with neutral.
Answer;
-Core
-Radiative zone
-Conventive zone
Explanation;
-There are three main parts to the Sun's interior: the core, the radiative zone, and the convective zone. The core is at the center. It the hottest region, where the nuclear fusion reactions that power the Sun occur.
-The radiative or radiation zone; Its name is derived from the way energy is carried outward through this layer, carried by photons as thermal radiation.
-The third and final region of the solar interior is named the convective (or convection) zone. It is also named after the dominant mode of energy flow in this layer; heat moves upward via roiling convection, much like the bubbling motion in a pot of boiling oatmeal.
b. Allele change and microevolution
c. Slow adaptation, stasis, and expansion
Answer:
A. Migration, genetic drift, speciation and natural selection.
Explanation:
Migration, genetic drift, speciation and natural selection factors are common to both .Gradualism and punctuated equilibrium are two ways of the evolution. Gradualism is selection and variation that happens. Small variations are fit an organism. In punctuated equilibrium, change comes in spurts. There is a period of very little change, and only few huge changes occur, often through mutations in the genes of a few individuals. Mutations are random changes in the DNA. That are not inherited from the previous generation, but passed in next generation. Though mutations are often harmful, the mutations that result in punctuated equilibrium are very helpful to the individuals in their environments.
Answer;
-Transcription;
Explanation;
-Gene expression involves the process of transcription and that of translation.
-Transcription, which takes place in the nucleus of a cell, involves the synthesis of a messenger RNA (mRNA) from a DNA template. The process is catalyzed by the enyzme RNA polymerase.
-The mRNA synthesiszed from transcription then undergoes the process of translation outside the nucleus (cytoplasm) to form proteins, that may be used for various cellular functions such as regulating cellular reactions.
