AP BIO HELP! EMERGENCY QUESTION!!?
Hypotheses derived from laboratory experiments and field observations have been advanced to explain the origin of life on Earth. Starting with a probable prelife environment, describe the formation and evolution of the various trophic forms (nutrition types) up to and including unicellular organisms. Describe at least one experiment whose results support one of these scientific hypotheses.
Bio Help pleaseeeeee?
14: Large deposits of these algae are used in special kinds of porcelain and glass. pleurococcus diatoms jellyfish none of the above 15: The common green algae that has a spiral, ribbon-like chlorophyll body is Euglena spirogyra kelp ************** desmid 16: The reproductive bodies found on the underside of fern fronds are called Yeast Fungi *************** Bryophytes Sporangia 17: Mosses and liverworts are brown green ************** yellow red 18: Mosses and liverworts have true leaves stems both 1 and 2 neither 1 nor 2 ************** 19: Mosses and liverworts reproduce sexually asexually ************** both 1 and 2 neither 1 nor 2 20: Modern ferns show advance over mosses in greater specialization of tissues and purpose function both 1 and 2 ************** neither 1 nor 2 Can you check my anwsers pleasee
Bio Question Please Help?
We just did botany in AP too 1. Conifers have cones, shallow roots (water=surface area spread out), and needle like leaves...all of these can cut evaporation and the stem can hold water...it can undergo photosynthesis it different times if it holds the water 2. flowers and fruits 3. in gymnos and angios it is reduced to cells...it is merely the parasite on the plant (which is sporophyte)...in bryophytes....it is the actual plants (i.e. moss) and the sporophyte is the parasitic growth on it....it also needs no water for gymnos and angios to reproduce, but water needed for bryophytes. 4). seeds are a definite for the second i might put flower/fruits for angio only and cones for gymno/conifers only ... i would put no water to reproduce
Bio lab help? Evolution? 10 POINTS?!?
I've been have a lot of difficulty answering this today. I'm an eighth grader in advanced bio classes for the regents. This is from the Amino Acid sequences: indicators of evolution lab (you can google the pdf online to see the figure) Question: More than 100 locations were not listed in Figure 1 because the amino acid was the same in all eight species. One possible explanation is that no mutations occurred in the codons for those locations. Suggest another possible explanation. Hint: Think about why some mutations are harmful. Try your best, & Thank you so much xo ❤✌
Biology Help concerning photosynthesis please?
Why do artificial plant growth lights have a light spectrum that favors the blue and red portions of the spectrum? Why are the leaves of trees green in summer? In the order of visibility, arrange the colors in chlorophyll. Photosynthesis increases at a steady rate with light intensity, but eventually plateaus. Why is this?
Help! Free response Biology question and I haven't the clue!!!!?
Intraspecific competition is something that affects reproductive success in a population. It is defined as when males compete with one another for the attention of a female. If it is a fight, the stronger of the two males wins, affected the natural selection in a population. Basically, the stronger individuals are favored, and therefore more likely to survive and reproduce. This changes the gene pool of a population, allowing more space for alleles that are strong over weak. Hope this helps!
