Answer: The correct option is B (self-replicating molecules, such as RNA and DNA)
Explanation:
The current theory of the process of evolution makes use of present day knowledge of genes and chromosomes to explain the source of genetic variation upon which natural selection works. These genes are discrete units of inheritance which determine hereditary characteristics. All the information for the inheritable characteristics of an individual are contained in these genes.
When a cell divides, the genes duplicate themselves so that each daughter cell has an identical set of genes as the original parent cell. These genes are passed from parents to offspring in the gametes of the parents.
Gene are found in the DNA( Deoxyribonucleic acid) molecules or RNA (Ribonucleic acid) molecules. These molecules are capable of self replication due to a process called mutation. Mutations are random changes in DNA that alter genetic information and sin introduce new characteristics. They may occur
--> in body cells or
--> during gamete formation.
Thus, evolution from vesicles to true cells is through self replicating molecules through the process of mutation which is the raw material for evolution
Answer:
Please find the answer to the blank spaces in each statement of the attached image in CAPS.
1. All energy comes from the SUN
2. Plants, algae and some bacteria capture energy by PHOTOSYNTHESIS in their CHLOROPLAST.
3. Plants, animals, fungi, protists, and most bacteria release energy by RESPIRATION in their MITOCHONDRIA.
Note:
- Photosynthesis requires CARBON DIOXIDE (CO2) and WATER (H20) to make GLUCOSE (C6H12O6) and OXYGEN (02)
- Respiration requires GLUCOSE (C6H12O6) and OXYGEN (02) to make CARBON DIOXIDE (CO2) and WATER
Explanation:
The image in this diagram is depicting how energy flows from the ultimate source, which is the SUN to other living organisms. Plants, algae and some bacteria have the ability to capture energy from the SUN using pigments in their CHLOROPLAST in a process called PHOTOSYNTHESIS, which they use to synthesize their food. The process of photosynthesis requires CARBON DIOXIDE (CO2) and WATER (H20) to make GLUCOSE (C6H12O6) and OXYGEN (02) gas.
However, on the contrary, virtually all living organisms including: Plants, animals, fungi, protists, and most bacteria etc. release energy via an organelle called MITOCHONDRIA in a process called RESPIRATION. The process of respiration requires GLUCOSE (C6H12O6) and OXYGEN (02) to make CARBON DIOXIDE (CO2) and WATER.
Cellular respiration is the process of oxidizing food molecules, like glucose, to carbon dioxide and water.
hope this helped ^^
