Chemicals produced by a plant that control its growth and development are called hormones. → True

A plant's roots grow away from a rock they hit in the soil. This is an example of positive thigmotropism.→ False

Chlorophyll speeds up the rate at which a plant's cells grow and controls a plant's response to light. → False

The critical night length for a certain plant is 10 hours. This plant will flower only when nights are shorter than 10 hours. → False, the plant will flower if the night length is longer than 10 hours.

A plant's adaptation that helps it survive freezing temperatures and lack liquid water is dormancy. → True

The blooming of poinsettias in winter and irises in spring is an example of phototropism. → False, the blooming of poinsettias in winter is as a result of photoperiodism

What are Plant hormones?

Plant hormones are chemicals produced by the plant for the control of plant growth and development.

Positive thigmotropism is a response towards a touch stimuli while negative thigmotropism is a response away from a touch stimuli.Chlorophyll is the green pigment in plants that allows photosynthetic activities to take place in green plants.Seed dormancy is the ability of the seed to be dormant when conditions are not favorable for its survival.Phototropism is the response of plants to the source of light.

True is the answer. hthhth

There really doesn't seem to be anything remotely advanced about this question, especially for high school.that being said, the actual correct answer may depend on the lesson you received.but i'll use common knowledge to you out here.  an atlas is a map, a flat map which depicts the world, all the continents and large bodies of water and etc.  an almanac is basically a yearly calendar. this depicts all the stuff that happened during the year it was released after, such as important events, sporting stuff, astronomical data, etc. it really depends on what type of almanac you go for.encyclopedias contain vast knowledge about just about everything important around the globe. each encyclopedia is generally focused on a topic and it's relating topics, ordered by each book alphabetically.  information resource can be anything. internet, newspaper, talking dog of pure wisdom (joking), the bible (or the religious book for whatever religion is in question), etc. all of these are considered information resources, as they all provide information on their respective topics (the internet is pretty much all topics)now, once again, your true answer will be based on whatever it is you learned, which i would not know. my answer will simply be using common knowledge.but your answers that line up with weather, sports, and business would be an almanac, information resources, and encyclopedia.  unfortunately, in today's world, they have books for everything. they have almanacs for weather, sports, and business, and they also have encyclopedia's for those as well. and of course, you can find all of that using information resources as well.  the only truly incorrect answer here is atlases.  ~hope this !
