Arose plant inherited two alleles for white flower petals.
which conclusion is best supported by the given information?
each parent had at least one allele for white petals.
each parent must have had more than one allele for white petals.
only one parent had one allele for white petals.
only one parent had two alleles for white petals.

Each parent had at least one allele for white petals.

Explanation:

According to the law of inheritance, it is necessary that each offspring must inherit one allele from each of its parents for a given gene.

Since in the given question, a rose plant inherits a white flower petal allele, it is necessary that the plant must have an inherited one allele from each parent, therefore, the two parents must have had at least one allele for white petal.

The cross is shown below ,

W---> red petal

w > white petal

Atleast one allele => Ww X Ww ---> WW Ww Ww ww

More than one allele => ww X ww > ww  

Here ww is the offpsring with white petals.

The correct answer is A. Each parent had at least one allele for white petals.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.  

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
