Answer:
Explanation:
As plants because they are autotrophic in their mode of nutrition.,They have photosynthetic organelle which can be used to synthesise their food by themselves.Thus they contain membrane bound chloroplast,the photosynthetic organelle peculiar to plants .They also contain mitochondria and nucleus which are all present in green plants.
In addition some algae undergo asexual reproduction which is peculiar to green plants.They are different due to lack of complexity of tissues e.g xylem,phloem present in plants etc.
They are similar to animals because they contain membrane bound organelles of mitochondrial,nucleus .These are the characteristic feature of Eukaryotas They are also capable of sexual reproduction ,and locomotion with the aid of flagella.(Chlamydomonas)
Explanation:
It is produced industrially by fermentation using yeast or bacteria. Marmite's defining ingredient is made from brewer's yeast heated to create glutamic acid, which is used by farmers to increase plant growth and boost crop yields.
Answer:
It seems arachnids are the only animals with 8 legs. Octopuses may appear to have 8 legs, but 6 of them are actually arms and therefore do not count.

Arthropods include such animals as insects, spiders, ticks, centipedes,millipedes, crayfish, lobsters, mites, and scorpions. One class of arthropodsis the arachnids which include spiders, scorpions, and mites. Spiders have two main body parts and eight legs. Insects make up another class of arthropods.
Answer: Option (C)
Explanation: Wegener's theory of Continental drift was replaced by a modern theory called the 'plate tectonic theory'. This theory was able to prove what wegener could not and so was universally accepted.
The new evidences supporting this theory were-
- The coastlines of east America and west Africa are similar in shape suggesting that they might have existed together once upon a time
- Similar fossils were found at different continents such as the glossopteris fauna
- Similar rock sequences found at different places determined by the correlation method
Hence the correct option that satisfies the above question is option (C)
