Answer:
Directional selection
Explanation:
Directional selection is a type of natural selection that favors one extreme phenotype of a genetic trait due to its survival and reproductive advantage to the individuals over another extreme phenotype and the intermediate phenotype.
In the given example, the thick-leaved plants are better adapted to a drier climate due to reduced water loss. Directional selection favored the plants with thick leaves which in turn produced more progeny. Over the generations, the population evolved into the one having more number of thick-leaved plants.
D. A plant using sunlight to make good
Answer:
A) rRNA makes up the ribosome.
B) tRNA carries amino acids to ribosome.
E) mRNA code is read to determine the sequence of amino acids in the protein.
Explanation:
The F Ring, the Cassini Division, and the C Ring are bright ring features. They are bright due to the low concentration of materials within them, which allows sunlight to shine through.
Answer: A. Research into a phytochemical from a plant which might inhibit cancer development.
Explanation:
The chemoprevention is a process of utilization of chemical formulations such as medication, supplements and vitamins to the stop the growth of cancer cells. This is necessary and important for people which are at high risk of developing cancer.
The research for the phytochemical derived from the plants can be an example of chemoprevention as this will help in inhibiting the cancer development.
