WE HAVE STEM BRAINS :}
Yes. For photosynthesis to occur a chemical reaction has to take place using chloroplasts and sunlight and water, to result in the production of glucose,water and oxygen. If any of the reactants or products are removed, the reaction does not occur. Thus, yes we require chloroplasts to allow an organism to undergo photosynthesis.
Answer: f. only b. and c. are examples of homozygotes
Explanation:
Diploid cells (all non-reproductive cells) have two copies of each gene, called <em>alleles</em>, one obtained from the father and one from the mother. In genetics, an organism is a homozygote for a gene if both alleles are the same. In contrast, heterozygotes have different alleles for the same gen.
Genes are represented with a letter, and you can differentiate between <em>alleles </em>if the letter is uppercase or lowercase.
For example, if you wanted to represent the gene that encodes a flower color, you could call A the 'red' version of it and a the 'blue' version of it. A plant would be homozygote for that gen if it had the same version for both alleles, AA or aa.
Answer:
motions of the planets in the solar system. They were derived by the German astronomer Johannes Kepler, whose analysis of the observations of the 16th-century Danish astronomer Tycho Brahe enabled him to announce his first two laws in the year 1609 and a third law nearly a decade later, in 1618. Kepler himself never numbered these laws or specially distinguished them from his other discoveries.
