As blood pressure increases and the hearts is working harder the most vulnerable arteries area are those <u>Located near the heart, because they are absorbing the most shock.</u>
<u></u>
Explanation:
When the heart pumps blood, the highest pressure is felt close to the heart. This is why the aorta, the artery that carries blood away from the heart is made up of thick walls to withstand this pressure, otherwise, these vessels would rupture. Away from the heart, this pressure lessens, and the blood vessels are not so thick-walled.

Answer:
1.The group of organisms with cells which contain of nucleus and other membrane bound organelles are called Eukaryotes. These organisms have their DNA arranged in the chromosomes, bounded by histones proteins. They have diversity of forms, thus they can be colonial, unicellular or multicellular in forms. Their cells reproduced by mitosis and meiosis for gamete formation.
Reproduction can be sexual and asexual. Their ribosomes are found in the cytosol, and they are larger than that in prokaryotes, but ribosomes in chloroplast and mitochondria are similar as that in the Prokaryotes (70s). Plants and complex animal cells are examples.
Group of unicellular organisms which lack membrane bound nucleus, and other organelles, are called Prokaryotes. Their two domains are the bacteria and archaea. They reproduce asexually only, by fusion of gametes. Due to lack of membrane bound organelles, their water soluble components and cellular inclusions (metabolites and DNA) are found in the cytoplasm bounded by the cell membrane.
<u>When viewed under microscope. Prokaryotes are similar to Eukaryotes as follows. </u>

D) Ecological systems often remain in balance if only one factor is altered.
Ecological system can affect one another regardless of how small or great the factor that was altered. This can have gradual and insidious effects on the ecosystem. <span>Ecosystem is
encompassing all the life on earth in the physical environment that
supports it. An ecosystem involves both the biological (plants, animals,
human beings) and non-biological (land, water, soil, and atmosphere)
community which interacts as a system. More importantly, the living
things are very dependent on the abiotic community since it cannot
survive by itself.</span>
