Answer:
Spores are produced by bacteria, fungi, algae, and plants. Bacterial spores serve largely as a resting, or dormant, stage in the bacterial life cycle, helping to preserve the bacterium through periods of unfavourable conditions.
Answer:
Base pairing occurs via hydrogen bonds between bases in complementary strands of DNA.
Explanation:
I think it’s A. The plasma membrane
15 degrees Celsius is colder than 20 degrees Celsius. It gets colder as the temperature decreases.
Gregor Mendel chose pea plants for his experiments because they are easy to raise, have many offspring per mating, can fertilize themselves and have varieties in genotype and phenotype that are easily observable.<span> These characteristics make pea plants ideal in the study of genetics and heredity.
</span><span>Mendel observed that his pea plants had several distinguishing physical features, such as plant size and pea color, that were governed by basically two alleles, or forms of genes. In general, pea plants grow well with minimal supervision and care. They can self-fertilize, so Mendel could pollinate the plants himself. The large number of offspring produced per mating gave Mendel a good number of plants to observe and work out the ratios of dominant and recessive alleles.</span>
