Answer:
Domains
Explanation:
Living organisms are divided into three domains:
Archaea
Eubacteria
Eukarya
Organisms are divided into these three domains based on genetic similarities or closeness. Archaea and Eubacteria are domains that consist of prokaryotes or prokaryotic cells.
Prokaryotes in the domain Archaea differ from those in Eubacteria because of certain characteristics like their ability to live in extreme environments and the absence of the peptiglycan in their cell walls.
Prokaryotes in the Eubacteria domain have peptidoglycan walls and RNA unique to them.
Organisms uner Eukarya, as the name suggests, have eukaryotic cells meaning the have an enclosed or membrane-bound nucleus.
Answer:
mitochondria and chloroplast
Explanation:
Mitochondria : generates energy
Chloroplast : converts energy from solar energy to chemical energy in form of ATP
Steps of the scientific method:
1. An observation is made.
2. A problem is defined or a question is asked.
3. A hypothesis is proposed.
4. A controlled experiment is set up.
5. Data is collected and analyzed.
6. Conclusions are made.
7. Process is repeated to verify results.
Examples of Scientific Method:
1. Raspberries did not grow well this year.
2. Why did the raspberries not grow well this year?
3. The raspberries did not grow well because we did not get much rain.
4. Raspberry plants are placed in moderately lit areas all receiving the same amount of light each day. Each plant will receive different amount of water. The size of the berries will be recorded daily once the plants begin to produce berries.
5. The raspberry plants receiving 1 cup of water daily grew to 1/2 " in diameter and those receiving two cups of water grew to 3/4 " in diameter.
6. The raspberry plants receiving the most water grew the biggest. Therefore, the hypothesis is supported that this year's raspberries did not get enough rain.
7. Repeat experiment.
Answer:
a) Both DdPp
b) Yes 3.8%
c) In plant A, the dominant allele D and P are coupled (DP, dp), In plant B they are in repulsion (Dp, dP).
