Wow! this si a huge question but analyzing all the datils from ths option you give me I have to say that C option: <span>Heat energy became trapped in the atmosphere by greenhouse gases and was used as an energy source in the building of macromolecules, is the one that gets closer to what the scientists have said recently. Take into account for example, the examinations of Dr. Stanley Millers. I think this can help you</span>

A heterozygous round seeded plant (Rr) is crossed with a homozygous round seeded plant (RR).
igomit [66]
So I don’t see answer choices here, but your answer is 50% of the offspring will be homozygous dominant with RR, and 100% of them will carry a homozygous dominant gene of Rr

If you take the two sets and put them into a punnett square, it would look like this (image attached):

When the two sets of alleles are crossed, you would end up with half of your pairs being fully dominant (RR), and the other half being dominant while containing a recessive gene (Rr). Since there’s only one recessive gene in these pairs, it gets overridden and the pair itself is dominant.

So your answer is 50% will be homozygous dominant with RR!

C

The "Nucleus" contains the genetic information of the cell in the form of deoxyribonucleic acid (DNA) or chromosomes and thus, controls cell growth and multiplication. It is also the site of DNA replication (formation of an identical copy of DNA).

While the "Golgi apparatus", or Golgi complex, functions as a factory in which proteins received from the ER are further processed and sorted for transport to their eventual destinations: lysosomes, the plasma membrane, or secretion.

Plant cells do not perform respiration, so A,C, and D couldn't be correct but they don't digest either. so gain energy plants go through a light dependent reaction and the Calvin cycle which makes up photosynthesis.

You will develop a brief portfolio detailing the history of tsunamis in a modern society that could be used to teach others.
Maru [420]

The 2004 Sumatra Earthquake and Indian Ocean Tsunami gave us a vivid description of menace of major tsunamis. It also suggested that tsunami science and engineering were inevitable to save human society, industries, and natural environment.

An answer can be found in Japan. Japan is the country the most frequently hit by tsunamis in the world. The experiences are well documented and are continued as the local legends. In 1896, the tsunami science started when the Meiji Great Sanriku Tsunami claimed 22,000 lives. An idea of comprehensive countermeasures was officially introduced after the 1933 Showa Great Sanriku Tsunami. The major works taken after this tsunami, however, were the relocation of dwelling houses to high ground and tsunami forecasting that started in 1941. The 1960 Chilean Tsunami opened the way to the tsunami engineering by elaborating coastal structures for tsunami defense. The 1983 Japan Sea Earthquake Tsunami that occurred during a fine daytime cleared the veil of actual tsunamis. The 1993 Hokkaido Nansei-Oki Earthquake Tsunami led to the practical comprehensive tsunami disaster prevention used at present, in which three components, defense structures, tsunami-resistant town development and evacuation based on warning are combined.

The present paper briefs the history of tsunami research in Japan that supports countermeasures.
