Answer:A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal.

<h3><u>Answer;</u></h3>
Vestigial Structure
<h3><u>Explanation;</u></h3>
- <em><u>Vestigial Structure are structures that have no apparent function and appear to be residual parts from a past ancestor.</u></em>
- Vestigial structures are normally homologous to structures that are functioning normally in other species and therefore may be considered evidence for evolution.
- Other examples of vestigial structures include; the human appendix, the pelvic bone of a snake, and the wings of flightless birds.
Answer:
(1) actively transport molecules in an organism
Explanation:
ATP (adenosine triphosphate) is a nucleotide made of the nitrogenous base(adenine), the sugar(ribose) and three phosphate groups which are covalently linked togther and attached to ribose.
ATP fuels cellular activities by transferring a phosphate group as seen in the attached image to a different molecule (this process is refereed to as phosphorylation).
California is home to the largest, tallest, and oldest trees on earth, all of which are gymnosperms.
Gymnosperms are plants that have seeds and are usually coniferous trees. Given that those largest, tallest, and oldest trees are sequoias, this seems to be the correct answer.
Nonvascular plants are quite small. Seedless vascular plants is also incorrect, because sequoias have seeds. Angiosperms are flowers.
