Some plants rely on the wind to reproduce an example is it’s important for plants to use the forces of nature to reproduce because 1. 1a white tuft of dandelion seeds 2a spiked burrs surrounding seeds 3a hard shell on a walnut? 2. 1b require pollination to reproduce 2b reproduce only asexually 3b cannot move about freely?

1a and 3b.

Explanation:

I don't know if I read that right, but dandelion tufts blow away and plant because of the wind, otherwise they cant move freely.

1. 1a White tuft of dandelion seeds

3b cannot move about freely

Explanation:

The White tuft of dandelion seeds refers to the feathery filaments and seeds. It is carried along with moving air away from the parent plant. The wind carries the seeds of dandelion to other places. Once the seeds find suitable substratum and growth conditions, they germinate and form a new plant.

Since plants can not move from one place to another in search of better growth conditions and substratum, they depend on air, water, other animals, etc. for dispersal of their seeds.  

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure

answer: i don't know

explanation:

you need to provide a picture, otherwise i can't tell you.

if you can provide one, i'd be more than happy to you with this!
