Answer:
The parent's genotypes are:
Ddpp - tall, white parent
ddPp - dwarf, purple parent.
Explanation:
This question involves two different genes coding for height and flower color in pea plants. The alleles for tallness (D) and purple color (P) are dominant over the alleles for dwarfness (d) and white color (p) respectively.
According to this question, a tall plant with white flowers is crossed with a dwarf plant with purple flowers to produce the following proportion of offsprings: 1/4 tall purple, 1/4 tall white, 1/4 dwarf purple, and 1/4 dwarf white.
Since some of the offsprings contain recessive alleles for both or either genes, the dominant traits of the parent is controlled by an heterozygous genotype. This means that the tall plant with white flowers has a genotype: Ddpp while the dwarf plant with purple flowers has the genotype: ddPp. In a cross between Ddpp × ddPp, 1/4 of each combination of alleles is produced in the offsprings (see punnet square in the attachment).
B. Protists more closely resemble members of other eukaryotic kingdoms than they do other protists.
Explanation:
It is difficult for scientists to classify protists into one kingdom because they closely resemble member of other eukaryotic kingdoms than they do other protists.
The protists have a wide variations among themselves that makes them very difficult to classify.
- Protists have a wide-range of diversity within them and they flaunt every rule used to classify them.
- Protists have also shown characteristics of different kingdoms between them.

Answer:
Root hair cells are alive and therefore need energy, which is why root hair cells contain many mitochondria in them. Root hair cells don't contain chloroplasts. Chloroplasts are used by the plant to make food using light energy. Since the roots aren't exposed to any form of light, they have no need for chloroplasts.
C. A new source of freshwater
Explanation:
The situation that would most likely increase the carrying capacity for humans in a certain region is the availability of new sources of freshwater.
In ecological terms, the carrying capacity of a place is the the number of people, animals, or crops which a region can support without environmental degradation.
- A new source of freshwater provides new resources for the ecosystem.
- In the freshwater, more fishes are available, more plants can grow around and a lot of biological activities can progress.
- Water is essential for life.
- Fresh water sources are incentives for choosing to live in a place or not.
- A fresh water source increases the carrying capacity for humans in a certain region.
