Answer: The phenotype of the genotype (rr) is wrinkled seeds.
Explanation: Dominant allele or gene is one which has the ability to express itself outwardly when it occurs together with a recessive allele. Dominant alleles are usually denoted in upper case for example R, T, A. Recessive allele or gene is one which lacks the ability to express itself in the presence of a dominant gene or allele. It is usually denoted in lower case, for example r, t, a.
Since R is for round seeds and r is for wrinkled seed; R is dominant while r is recessive, r will be able to express itself outwardly only when it occurs in a homozygous state such as in (rr). Therefore rr will manifest outwardly in the plant as wrinkled seed.
Answer:
The producers (or plants) photosynthesize to get their energy from the sun.
The primary consumers eat the plants, which gives them that energy indirectly.
Secondary consumers who prey on the primary consumers get energy from the producers through the primary consumers, and so on.
Explanation:
Plant decomposers would operate above the producer level. Two examples are earthworms and fungi. These would decompose dead plant matter into nutrients that are then re-assimilated by plants. Animal decomposers operate within the consumer levels, and would include species such as maggots, shrimp, clams, crabs, lobsters and flat<span>worms</span>. Nutrients recycled by these decomposers would also be recycled back to the producers.
Answer:
Scientists have been concerned that human activities could cause more plants and animals to become extinct than any point in the past. Along with human-made changes in climate (see above), some of these extinctions could be caused by overhunting, overfishing, invasive species, or habitat loss
