The right answer is D) 9 groups of 3 microtubules
Centrioles are the constituents of a so-called centrosome structure: every animal cell has a centrosome, which is made of two centrioles and which together form a functional unit. A centriole consists of nine triplets inclined microtubules, surrounded by a number of proteins.
It results from the composition of the cell membrane. The cell membrane consists of a phospholipid bilayer, which have hydrophilic heads and hydrophobic tails. Hope this helps! :)
Answer:
Green leaves have water wich makes them hard to burn
Explanation:
Dry leaves have no relaining water in them, whick makes them very succeptible to fire, whereas the green leaves are green and therefore still have water in them. This presence of water makes them more resistant to fire.
Photosynthesis: the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.
Answer:
20
Explanation:
Haploid cells contain a single copy of each chromosome. Diploid cells contain two copies of each chromosome. So if a haploid cell in an organism contains 10 chromosomes - the diploid cell will contain 20 chromosomes.
In humans, nearly all of our cells are diploid, and contain 46 chromosomes. Our haploid cells - the gametes (egg and sperm cells) - contain 23 chromosomes (one copy of each chromosome). When these fuse during sexual reproduction to form a zygote - the diploid state is restored and the zygote has 46 chromosomes.
