Polychaeta are more numerous than oligochaeta
Example of polychaeta is sand worm
While oligochaeta is earth worm
Both are free living organisms
Answer:
1 .photosynthesis is the process by which green plants and certain other organisms transform light energy into chemical energy during photosynthesis in green plants light energy is captured and used to convert water, carbon dioxide, and materials into oxygen and energy which organic compounds
ANSWER -.which means we need photosynthesis to have light, energy, and carbon dioxide.
2. the products of photosynthesis are glucose and oxygen photosynthesis takes in carbon dioxide and water and combined them into presence of energy from the Sun to make food for the organism photosynthesis occurs in membrane-bound structures called chloroplasts
ANSWER- glucose and oxygen
3. plants synthesize their own food from simple substances like carbon dioxide and water in presence of light during photosynthesis. The plants need energy for the synthesis of food that is obtained by sunlight the solar energy is in trapped by green pigment chlorophyll, present in chloroplasts
ANSWER- carbon dioxide, water, sunlight
The given question is incomplete as it lacks the group of statements require to answer from, however, the correct group of statements is as follows:
A. She should use scientific investigation because she will need to analyze the results.
B. She should use technological design because she will need to design an experiment.
C. She should use scientific investigation because she will need to communicate her findings.
D. She should use technological design because she will need to build a prototype.
Answer:
The correct answer would be - option D. She should use technological design because she will need to build a prototype.
Explanation:
Rachel wants to develop a remote-operated lamp that can work by controlling by remote for that she needs to make a prototype to understand the technology and technical aspect of the product she wanted to develop.
Prototypes are technical designs or pictures that help in understanding the problems earlier about the product and can be solved by avoiding such issues in early models or protoptypes.
Answer B. Comets have very elliptical orbits that usually take them far beyond the orbit of Pluto, but also take them closer to the Sun than Earth.
