According to the World Resource Institute, biodiversity is the variety of the world's organisms, including their genetic diversi

ty. In a world of genetically modified (GM) crops, agriculture is greatly reducing the genetic diversity of the plants on Earth. If we ignore genetic diversity while we develop GM products, we risk a disease or pest emerging that will wipe those types out. One answer to this problem is seed banks. Storage of material in the form of seeds is one of the most widespread and valuable ex-situ approaches to conservation. All BUT ONE is an advantage of seed banking over other ex-situ methods of biodiversity conservation. That is
A) seed banks take up little space.

B) seeds are viable for a very long time.

C) seed banks are expensive to maintain.

Given what you know about the endosymbiotic theory, which region of the chloroplast below would you expect to be derived from th
san4es73 [151]

Answer:

Photosynthetic lamellae

Explanation:

The cyanobacteria were the first successful photosynthetic cells present on the Earth which were able to convert the light energy into the chemical energy.

The endosymbiosis theory suggested that these cyanobacteria were engulfed by the eukaryotes and the cyanobacteria get transformed into the chloroplast.  

The region of the chloroplast that was formed in the cyanobacteria before the endosymbiosis happened was the photosynthetic lamellae which contained the chlorophyll molecule and thus is the correct answer.

Thus, Photosynthetic lamellae are the correct answer.

How did the Rf values differ between pigments and solvents?
lara31 [8.8K]

Answer:

The Rf values indicate how soluble the particular pigment is in the solvent by how high the pigment moves on the paper.

Explanation:

The Rf values indicate how soluble the particular pigment is in the solvent by how high the pigment moves on the paper. Small Rf values tend to indicate larger, less soluble pigments while the highly soluble pigments have an Rf value near to one.

What can you do to ensure that you will continue to be motivated for the duration of your fitness program?
avanturin [10]
1. Make a goal for yourself. When you finish your fitness program(achieve your goal) you can reward yourself with like icecream or a small treat.

2. Make working out fun so that you will keep wanting to do it. For example, work-out or go to the fitness program with a friend, listen to music while doing it, etc.

3. You can make yourself motivated by watching fitness videos and basically watching things to get inspiration(trust me this works).After you watch the vids, your gonna want to keep going to the fitness program cause of all the benefits and things like that. 

4. Ask a friend or someone to push you to keep going(if all else fails and you wanna quit) They will annoy you so much that it would just be better to go to the fitness program than hear them annoy you.

5. Think why your going to regret not going. This is gonna make you want to go to the fitness program.

6. Honestly if the others don't work, do it for the pictures and so that you can brag to people that you work out and stuff.

That's all I got for now. Hope it helped motivate you to keep going to that fitness program <span />

What is a transformer?!?!
Vladimir79 [104]
The transformer is a static electric machine (because it contains no moving parts) belonging to the broader category of converters. In particular the transformer to convert the parameters of voltage (V symbol unit [V] volts) and current (symbols The unit [A] amperes) input than output, while maintaining constant the amount of power electrical (less the losses due to hysteresis and eddy currents). The transformer is a machine able to operate only in alternating current, because it exploits the principles of electromagnetism linked to variable flows. <span>The transformer has paramount importance in today's world: without it, the electricity transmission grids that connect power plants to millions of homes and industries could not function</span>
