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.

What cross will result in all heterozygous offspring?arrow_forward1.Steroids like testosterone and estrogen are nonpolar and large (~18 carbons). Steroids diffuse through membranes without transporters. Compare and contrast the remaining substances and circle the three substances that can diffuse through a membrane the fastest, without a transporter. Put a square around the other substance that can also diffuse through a membrane (1000x slower but also without a transporter).

- what are the answer from the bookarrow_forwardwhat is lung cancer why plants removes liquid water intead water vapoursarrow_forward*Example 2: Tracing the path of an autosomal dominant trait Trait: Neurofibromatosis Forms of the trait: The dominant form is neurofibromatosis, caused by the production of an abnormal form of the protein neurofibromin. Affected individuals show spots of abnormal skin pigmentation and non-cancerous tumors that can interfere with the nervous system and cause blindness. Some tumors can convert to a cancerous form. i The recessive form is a normal protein - in other words, no neurofibromatosis.moovi A typical pedigree for a family that carries neurofibromatosis is shown below. Note that carriers are not indicated with half-colored shapes in this chart. Use the letter "N" to indicate the dominant neurofibromatosis allele, and the letter "n" for the normal allele.
