Explanation:
MRNA is a short lived form of genetic information that is used in transcribing the genetic information, hence it is not very useful for analysis since it is fragile and wrong transcriptions happen quite often. SNPs (Single Nucleotide Polymorphisms) are a form of genetic mutation; they are more frequent than most other mutations since a single transription error may lead to this. While SNPs are important in genetic analysis and getting information about causes of disease, they are not very helpful in determining your maternal lineage. Similarly, while nuclear DNA contains a large portion of our genetic information, half of it is from our fathers and half from our mothers, so the analysis becomes hazy very soon. Mitochondrial DNA instead is directly passed down from mother to her offspring since the embryo contains only the mitochondria of the ovary. Thus, studying differences between mitochondrial DNA, one can gain information about his maternal lineage and go back to Mitochondrial Eve, the person from which all living persons have gotten their mitochondria from. Thus, the correct answer is c.
The human brain can be divided into three<span> main parts: the forebrain, midbrain, and hindbrain: 1/ The forebrain includes the several lobes of the cerebral cortex that control higher functions.</span>
Answer:
mitochondria
Explanation:
Mitochondria is known as power house of a cell
Answer:
Explanation:
Cell which is the basic unit of life is affected by the interactions with biotic and abiotic factors such as temperature, sunlight. Organisms are made up of cells and they respond differently to temperature changes, sunlight, water availability. Some cell perform better at some certain range of temperature while some cannot.
Organism itself are affected by the interaction of some of this factors this include water and nutrients availability. Distribution of organism in a particular habitat is greatly influenced by availability of water and nutrients it lead to competition for survival among organism. Population density and species diversity also influence community and ecosystem. Population determines how resources is allocated in a community and it affect the activities of the organism in that domain or territory.
