1. True. Establishing more sites for the protection of biodiversity across the world can go a long way and would have a chain reaction in the ecosystem. Thus, it will save a lot of our planet's biodiversity. 2. a. -Philiab. -trophicc. eco-d. eu-3. A habitat is where certain species, animals, or organisms naturally live, feed, reproduce, etc. Examples: ocean, rainforest, deserts. An ecosystem has two components: living and non-living organisms which interact with each other to maintain homeostasis. The primary difference between the two is the presence of interaction between the things in the environment.4. Energy5. Producers6. Sun7. (No choices provided) One of the top factors that threaten the survival of species is caused by humans, man-made phenomena. 8. Answer: Polar bears. Polar bears are endangered species and there are only approximately 20,000-30,000 polar bears left in the world. Their population had been decreasing due to habitat loss because of climate change. 9. Scientists based the background extinction rate on the number of known species that went extinct over a period of time in the past. They also based it on archaeological evidence of species that existed and went extinct years ago.
<span>The body is constantly changing, no matter what age. It has to maintain homeostasis, or balance at all times or illness/death occurs. If your body is weakened, it then becomes harder to maintain this state. If one component goes out of balance; ie, water content, it affects the whole body. Swelling(edema) CHF(serious heart problem) kidneys may be overtaxed/unable to release the extra fluid. As the body ages organs naturally become less efficient, therefore making homeostasis more challenging.</span>
Answer: Different eukaryotic cells contain different numbers and types of organelles depending on the specific tasks they must perform
Explanation:
Since living organisms with eukaryotic cells live in different environments and have diverse metabolic needs; each eukaryotic cell has organelles that have specific functions.
For instance:
Though, both fishes and humans have eukaryotic cells, they do not share all cellular organelles in common.
Thus, it is true that different eukaryotic cells contain different numbers and types of organelles depending on the specific tasks they must perform
Answer:
23, haploid
Explanation:
there are 23 chomrosomes in both a egg and sperm cell
this makes them haploid as they have a single set of unpaired chromosomes
hope this helped
