Reply:urinate on them , works every time!

Anyone know where I can find info on indiginous plants of the Yukatan?

Need info on plants that have their origins in that area. Especially any broadleafs and canes.

If you speak Spanish, a good resource in the UNAM, Universidad Nacional Autonoma de Mexico, that has various botanical texts that are authorative and up-to-date. If it is a particular plant, you are looking for you will probaly have better luck doing an internet search with a botanical encyclopedia online. Good luck!


What to spray my yard with?

I re-seeded Kyentucky Fescue last fall and have a fair stand, however, mouse ear chick weed and other broadleafs are really thick. I wanted to spray for the chickweed and the broadleafs. I read on the lable that 24d was a poor choice to kill chickweed and also that I couldnt overseed for a yr following treatment. I fear large areas will need to be seeded when the bradleafs die. So what can I spray with to get these weeds and still overseed in 2 weeks?

What to spray my yard with?
I've read all the answers that other people have given you, some are fair. Here's my advice, take it or leave it. Granular weed and feed (preferably Scots) will be your best bet. Weed and feed contains atrazine which will work if applied and watered in properly. Atrazine can only be applied when afternoon temps are no higher than 80-85 degrees. You must water the application in with no less than equal to 1/4 inch of rain. Water it in for 2 days in a row(twice daily). If you put it down without watering it in, your lawn itself could be damaged. Atrazine kills and will prevent weeds (for 4-6 weeks) from growing in your lawn. I'm very big on promoting the old school method of pulling weeds. The more you pull the less you have! Take a knife a get them from the roots up.
Reply:You shouldn't spray anything! It is very bad for the enviroment! It goes into the rivers and the fish die and then it comes around back to you when you eat the fish or drink water.
Reply:you can get a fertilizer called weed and feed it works pretty good
Reply:Roundup may be your answer. Check it out
Reply:Your garden store can recommend the correct "weed and feed" product for your area. If you have a really bad spot it might be worth using Round-up which kills most everything. Then reseed that area.
Reply:When we moved here 2 years ago all we had was weeds for a lawn. (This used to be a field) I did some grass seed last year which took off pretty well. Then I got some stuff at Lowes called Weed and Feed. It is supposed to kill many different types of weeds and feed your grass so that it can choke out future weeds from growing. Now my yard is almost all grass and very little weeds. Good luck. Oh, and it's not a spray it is granules.

How does fertilization of the lawn cooperate with appication of herbicide for weeds?

I understand that you dont want to overseed the lawn when you are trying to control weeds through herbicides , so since there isnt much of a window for doing this (in between pre-emergen in early Spring and Post Emergent in late Spring) , is it a good idea to apply fertilizer to the lawn?

and if so, how does this help or not help in killing the weeds (broadleaf or grassy) ???

How does fertilization of the lawn cooperate with appication of herbicide for weeds?
Feeding the lawn whilst trying to kill off broadleaf weeds will not help or hinder with killing them.

A 13.13.13. is simply a balanced feed, you could also use one with a higher nitrogen content.

The only minor benefit you would get is that the grass would grow quicker to colonise the spaces left by the dead weeds.

I am assuming that you talking about an established lawn where you are reseeding patches.

Ughhh i hate bio?

You are in an area with large trees that loose their leaves in the winter, this is mostly likely?

A. Temperate broadleaf forest

B. Taiga

C. Tundra

D. Either A or C

E. None of the above

Ughhh i hate bio?
It is a temperate broadleaf forest. Taiga is mostly evergreen, and the tundra doesn't have any trees.
Reply:Go to and look up what the words mean, and see which sounds like large trees that loose their leaves in winter. If you don't listen during the lesson, you will have to do extra work to understand later. Why don't you look through your text book?

I need Betta advice on plants, snails, and cycling....?

I set up a 2.5 gallon tank 4-5 days ago with dechlorinated tap water %26amp; put in some fish food to start the cycle. Yesterday I picked out my betta. I took him home, rinsed the gravel, %26amp; put it in with a small decoration %26amp; 2 small potted plants (one is a broadleaf anubias, the other didn't have a label). I floated his cup for about 10 minutes then put him in. He seems happy but no bubbles; he stays at the surface of the water (no gasping though). I fed him a few dried bloodworms this morning which he gobbled up. The water is still a little cloudy from cycling.

1. Is the setup OK? Why does he stay at the top? There's no filter or heater but the temp is 74 and I plan to do partial water changes.

3. If I get a tiny snail will my fish eat it in this small tank? Will the snail eat my plants?

4. Can I leave the plants potted?

5. Is it bad to only feed bloodworms?

6. Did I wait long enough before putting him in?

7. I'm nervous that when I change the water he will try to jump out.

I need Betta advice on plants, snails, and cycling....?
Bettas are air-breathers, and don't need deep water. They do just fine in a large vase (about 1 1/2 gallons).

Bettas are carnivores. and don't eat plants. Plants do not clean the water. Aside from appearance, they only provide cover for the fish. Since bettas spend most of their time at the top of the tank, plants at the bottom do nothing. I prefer pothos plants, a type of ivy that roots easily in water. I either clip long segments from existing plants, or purchase new ones, and remove/rinse all of the dirt off of the roots. Betta's love hanging out in the roots. The plants hang easily, and get their food from the water.

I had many bettas, all in huge vases, with colored glass "rocks". Once every week I set up new vases, added clorine eliminator, and allowed the water to reach room temp before switching the fish.

I found that using a fish net and big collander (spaghetti strainer), worked best. After removing the plants, I slowly pour the water out of the tank, through the net and into the collander. After the fish is in the net - I put him in the new vase.

As for food, get Betta pellets - available at any pet store or discounter that sells fish. Blood worms are fine for a treat, but not for long-term maintenance

Not all bettas will make bubble nests, especially if there are no females, or other males within sight. They tend to be more active if they have other bettas nearby.

Bettas don't live in lakes or ponds. They live in muddy rice patties, often subjected to drought. They can survive in a tiny puddle of mud. They really do not need, or enjoy regular fish tanks.

And yes, bettas can jump out of tanks. Just make sure the water level is at least 2" below the top of the tank.

If you should ever find your fish out of the tank - do not throw him away. Even after being completely dried out, they can still be alive, and recover. I had one who lived for years after his suicide attempt.

Good luck to you!
Reply:Your betta is stressed. It takes a little bit for bettas to get used to their new environment. keep his tank clean and feed him regularly. remove any uneaten food after 5 minutes. You did not cycle the tank in less than a week, since the tank is not cycled you will need to make sure you have a good liquid (dont get the strips, they are useless) test kit and keep an eye on ammonia (should be zero), nitrite (should be zero), and nitrate (try to keep under 20) levels. You can do that with frequent water changes. Keep his temp at 78 degrees. A snail will add extra waste to the tank that isn't needed. Snails can eat plants (depends on the type of snail). Some bettas will eat snails, some don't..just depends on the betta. Freeze dried bloodworms are fine fed as a snack, but should not be used as the staple food in your betta's diet.

Hope that answers all your questions, if not you can check out the website in my profile for more betta info.

1) in my opinion, i think he stays at the top waiting for food. my betta swims up to the top every time it sees me! you should put something in the tank to occupy him. A little hiding place, maybe?

2) I think it will be best not to get a snail because betta are independant, proud creatures and a snail may cause him to get stressed since he may think the snail is stealing his habitat.

3)as long as the plants arent in soil (because soil will cause the water to get dirtier.)

4)Bloodworms should be an occasional treat only, not the regular food. Buy regular betta food (the most simple ones are spherical brown grains) and give bloodworms as an additional treat.

5)Yes. I put mine in after about three minutes. You have to wait for the water to settle into room temperature or the betta will get a shock but what you did sounds fine.

6)That is possible although mine has never jumped out. But if you dont want to risk it, prop up a mirror against to pot you're going to keep him in while you change the water and your betta will be too busy just staring at the mirror thinking its another betta. (and dont worry when it looks like his face poofs up. he's just trying to frighten the betta in the mirror away.

Good Luck!
Reply:You should get him some Betta pellets just for some variation. Depending on the type of snail, it may be fine, and it may be a horrible idea. Mystery Snails are fairly large, won't eat plants, and will not breed like Guppies. All the snails that you find on live plants are no good. Before you know it, you'll have hundreds of them crawling through your tank. The Betta will not eat snails. The reason he stays at the top is because Bettas breath air (they don't use their gills to extract oxygen from the water). You will soon see him "gasping" for air, but that is just breathing. If you want, you can leave the plants potted (I don't but it really doesn't matter). As long as the temperature in the cup was similar to the temperature in the tank, it is fine. Email me if you have any questions...

Reply:1.) You have too many decorations in your 2.5 gallon tank. Keep only a minimum of one or two live plants. I would recommend two Micro Swords. Another suggestion would be one or two silk plants. Never get platic plants. They can tear the Betta's fins. Your Betta stays at the top because it perfers mid-top tank levels when inside an aquarium.

2.) Your 2.5 gallon tank should already have a built-in filtration unit already. As for a heater, I would recommend a Mini Heater.

3.) Get a Mystery Snail. You do not have to worry about the Betta bothering it. If you get live plants, chances are the snail will eat your plants. Go with artificial silk plants to keep this from happening.

4.) That is an option. Your plants will continue to grow either way.

5.) Bettas eat pellets that are made for them. Feed it between 6 to 8 pellets twice a day. The bloodworms are actually a treat for the Betta.

6.) Actually you were supposed to wait 15 minutes but he did turn out fine obviously.

7.) Get a small net so that next time you have to do a water change, you won't have to worry about him jumping out.

Hope all this helps.

I need some help answering a couple of questions.?
1) B one individual is homozygous recessive

This allows you to see, for example, if some recessive show up. The test cross determines if a phenotypically dominant organism has a heterzygous or homozygous genotype. If it is a homozygous genotype, all offspring are going to be phenotypically dominant. If it is heterzygous, some dominant and some recessive phentoypes appear.

2) A. Marine

Diatoms (Greek: διά (dia) = "through" + τέμνειν (temnein) = "to cut", i.e., "cut in half") are a major group of eukaryotic algae, and are one of the most common types of phytoplankton. Most diatoms are unicellular, although some form chains or simple colonies. A characteristic feature of diatom cells is that they are encased within a unique cell wall made of silica (hydrated silicon dioxide). These walls show a wide diversity in form, some quite beautiful and ornate, but usually consist of two asymmetrical sides with a split between them, hence the group name. Fossil evidence suggests that they originated during, or before, the early Jurassic Period. (

The fact that they are a type of plankton shows that they are in marine ecosystems

3) D. endergonic

end·er·gon·ic (ndr-gnk) KEY


Requiring energy: an endergonic chemical reaction

It takes energy for it to occur

I am 100% on all three answers
Reply:B. A test cross is when you cross the unknown with a homozygous recessive individual. Since the known is homozygous recessive, the genotype of the unknown will show up.

A. Marine. Diatoms are unicellular algae.

D. That's the definition of endergonic reactions.
