Answer:
Cis–trans isomerism, also known as geometric isomerism or configurational isomerism, is a term used in organic chemistry. The prefixes "cis" and "trans" are from Latin: "this side of" and "the other side of", respectively.
Fern spore germinates into prothallus.
Explanation:
Ferns are members of phylum pteridophyta, the vascular cryptogams.
These are first land plants which are known to have a distinct conducting system of xylem and phloem.
They reproduce by forming spores that germinates into a heart shaped gametophyte.
The gametophyte of the fern is called prothallus.
The heart shaped gametophyte has root like structure called rhizoids.
These rhizoids anchor the gametophyte to the substratum.
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.
The process cells use to grow and replace old cells is mitosis.
Objects/people have the same MASS at all times, but if the acceleration of gravity on the object changes, i.e. you go to another planet, the objects WEIGHT changes.
