<h3><u>Answer;</u></h3>
D) frequently, and sometimes rapidly
<h3><u>Explanation;</u></h3>
- The hypothesis that the Grants have been testing was about the natural selection shaping the beaks of different bird populations.
- <em><u>The Grants documented that natural selection takes place in the wild finch population frequently, and sometimes rapidly.
</u></em>
- The Grants' work showed that variation within a species increases the likelihood of the species' adapting to and surviving environmental change.
<span>As the pollen tube penetrates the ovule, it releases two sperm cells. As in gymnosperms, the ovule becomes a seed, encasing the embryo and endosperm in a seed coat. But unlike gymnosperms, in angiosperms the ovary containing the ovules develops into a fruit after fertilization.</span>
Answer:
C) The pea plant would be shorter with more branches compared to wild-type plants.
Explanation:
Gibberellic acid stimulates the stem growth by promoting elongation and cell division, so having this compound's gene underexpressed will make the plant shorter. On the other hand, cytokinins are located in young cells, particularly the buds, and stimulates its lateral growth. Having a plant with a overexpressed cytokinins gene will make the plant have more branches compared to wild-type plants.
Limestone contains calcium carbonate which comes from animals that have shells, it already has carbon. Other sources are ocean animals which create shells that combine both carbon and calcium. Their dead bodies also release carbon to the ocean. Limestone is also known as a sedimentary rock that has carbon. Outside the ocean, limestone emits the carbon and becomes part of the carbon cycle. In addition to this, limestones are widely used by people becomes a part of the carbon cycle. Its component is present on asphalt, animal feed.
