To determine:
The reason behind making so many acorns by the oak tree.
Introduction:
The acorns are the fruit of the oak tree. It is an oval nut, and its outer part is shaped like a cup. The fruit is formed from the ovary which consists of one or more seeds. If the fruit develops from a flower with one ovary and contains only one seed, it is called simple fruit. If the fruit develops from one flower containing many carpels, it is called an aggregate fruit.
To determine:
The reason behind having better reproductive success in dispersing the seeds far from the parent as compared to the one whose seeds fall at the base of the parent plant.
Introduction:
The seed dispersal is considered as the important function of fruits. The seeds are dispersed by animals, wind, and water. The wind dispersed fruits have wings or other structures that catch the air currents. The water dispersed fruits may drift across the water bodies before colonizing distant lands. The animal dispersed fruits are vibrant colored and they also have spines which help them to get attached to animals.

- How many milligrams of zinc did you consume on average per day over the 3 days? (See the Actual Intakes vs. Recommended Intakes Report with all days checked.) Enter the number of milligrams of zinc rounded to the first decimal place in the box below. ______ mg ?arrow_forwardthe direct output from molecular replacement is a coordinate file showing the orientation of the unknown target protein in the unit cell. true or false?arrow_forwardthe direct output from molecular replacement is a coordinate file showing the orientation of the unknown target protein in the unit cell. true or false?arrow_forward
- Did your intake of vitamin C meet or come very close to the recommended amount? yes noarrow_forwardWhich of the following statements about hydration is true? Absence of thirst is a reliable indication that an individual is adequately hydrated. All of these statements are true. Although a popular way to monitor hydration status, weighing yourself before and after intensive physical activity is not a reliable method to monitor hydration. Urine that is the color of apple juice indicates dehydration. I don't know yetarrow_forwardThree of the many recessive mutations in Drosophila melanogaster that affect body color, wing shape, or bristle morphology are black (b) body versus grey in wild type, dumpy (dp), obliquely truncated wings versus long wings in the male, and hooked (hk) bristles versus not hooked in the wild type. From a cross of a dumpy female with a black and hooked male, all of the F1 were wild type for all three of the characters. The testcross of an F1 female with a dumpy, black, hooked male gave the following results: Trait Number of individuals Wild type 169 Black 19 Black, hooked 301 Dumpy, hooked 21 Hooked, dumpy, black 172 Dumpy, black 6 Dumpy 305 Hooked 8 Determine the order of the genes and the mapping distance between genes. Determine the coefficient of confidence for the portion of the chromosome involved in the cross. How much interference takes place in the cross?arrow_forward
- What happens to a microbes membrane at colder temperature?arrow_forwardGenes at loci f, m, and w are linked, but their order is unknown. The F1 heterozygotes from a cross of FFMMWW x ffmmww are test crossed. The most frequent phenotypes in the test cross progeny will be FMW and fmw regardless of what the gene order turns out to be. What classes of testcross progeny (phenotypes) would be least frequent if locus m is in the middle? What classes would be least frequent if locus f is in the middle? What classes would be least frequent if locus w is in the middle?arrow_forward1. In the following illustration of a phospholipid... (Chemistry Primer and Video 2-2, 2-3 and 2-5) a.
