Answer:
1. The gametophyte generation is haploid.
2. The embryo is diploid.
3. The megaspore is haploid.
4. The sporophyte generation is diploid.
Explanation:
1. Gametophyte- The gametophytic generation is the structure which produces gametes in the plant. Since the gametes are haploid, therefore, the gametophyte us considered the haploid.
2. Embryo- The embryo is formed after the fusion of fertilization when zygote develops, therefore, is considered diploid.
3. Megaspore- the big size spore which is formed from by the meiotic division of the megasporocyte, therefore, is considered haploid.
4. Sporophyte- the sporophyte generation develops from the embryo which is diploid therefore is considered diploid.
Answer:
Scientists use creativity to determine which smaller questions are likely to yield results, imagine possible answers to their questions, and devise ways to test those answers.
Explanation:
<u>Answer:</u>
Greenhouse gas refers to any gaseous compound in the atmosphere that can absorb infrared radiation, thereby trapping heat and keeping it in the atmosphere. By increasing the heat in the atmosphere, greenhouse gases are responsible for the greenhouse effect, which ultimately leads to global warming.
<u>Examples why greenhouse gases in the atmosphere:</u>
- farming cattle releases methane
- farming rice in paddy fields releases methane
- burning fossil fuels in vehicles and power stations releases carbon dioxide
- deforestation releases carbon dioxide and reduces the absorption of carbon dioxide through photosynthesis

The answer to your question is...
Explanation:
Robert Hooke and Anton van Leeuwenhoek.
1/4. There is a 1/2 chance for each plant to pass on a gene for wrinkled seeds, and both must pass the gene, so we have 1/2*1/2=1/4.
