The organelles that scientists believed that it originated by symbiotic relationships between primitive eukaryotes and certain prokaryotes is known as chloroplast. Chloroplast contain chlorophyll which capture energy from sunlight that is used in photosynthesis .This energy is converted to ATP and NADPH
Answer:
Identical shape and structure.
Explanation:
Those organisms that reproduce sexually have high variations and differences between the parent and its offspring. They are not identical to each other because the offspring gains half characteristics from male parent and half from the female parent making it different from its parent. Identical feature is present in the organisms that reproduce through asexually means from only one parent so the identical shape and structure is not the cost of sexual reproduction.
The correct answer is option C, that is, it prevents the formation of ATP and NADPH, which are needed by the light-independent reactions to make sugars.
The herbicide atrazine combines with the D1 protein and inhibits the binding of plastoquinone. By obstructing the binding of plastoquinone, the procedure of photosynthetic transfer of electron is disturbed, and thus, the production of ATP and NADPH in the chloroplast gets compromised.
This leads to an incapacity to fix carbon dioxide and generate the nutrients required for the plant to live. The block in the transfer of electrons also results in an oxidative stress and the production of radicals that lead to brisk cellular destruction.
Crossing over does not prevent homologous chromosomes from separating during meiosis, hence, the statement is false.
CROSSING OVER:
- Crossing over is the process whereby non-sister chromatids of homologous chromosomes exchange their genetic materials.
- Crossing over occurs specifically during the prophase I stage of meiosis I. Via this process, genetic diversity is likely to occur in the daughter cells.
- Crossing over only assures that genes of homologous chromosomes are recombined, it does not stop them from separating in the Anaphase stage.
- Therefore, crossing over does not prevent homologous chromosomes from separating during meiosis, hence, the statement is false.
