9. In pea plants purple flowers are dominant to white flowers.
If two white flowered plants are cross, what percentage of their
offspring will be white flowered?
10. A white flowered plant is crossed with a plant that is
heterozygous for the trait. What percentage of the
offspring will have purple flowers?
11. Two plants, both heterozygous for the gene that controls
flower color are crossed. What percentage of their offspring
will have purple flowers?
What percentage will have white flowers?
Answers
#10 would be 50% purple flowers and 50% white.
#11 would be 75% purple and 25%white.
A white flowered plant is crossed with a plant that is heterozygous for the trait. The percentage of the offspring will have purple flowers is 100%.
What do you mean by heterozygous?The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).
If the two versions are different, you have a heterozygous genotype for that gene. For example, being heterozygous for hair color could mean you have one allele for red hair and one allele for brown hair.
An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB. An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype.

Explanation:
The introduced species is also called as an exotic species. The exotic species is a species which is not native to a particular location or area but is introduced by humans either accidentally or with the desired species. Such species can be invasive means, it can compete with the native species for resources and can reduce the population of native species.
The given situation is an example of introduction of new species. The weeds are introduced exotic species which could have come along with the desired variety of wheat required for farming in the prairies.

Why is energy transformed from one form to others?
Answers
Answer:
Energy transformation is when energy changes from one form to another – like in a hydroelectric dam that transforms the kinetic energy of water into electrical energy. While energy can be transferred or transformed, the total amount of energy does not change – this is called energy conservation.

A lake has very deep water at the bottom, in the benthic zone. Why is it more difficult for plants to live in the benthic zone of this lake than in the limnetic zone
Answers
Answer:
See the answer below
Explanation:
It is quite difficult for plants to survive in the benthic zone due to the limited penetration of light in the zone when compared to the limnetic zone. The limnetic zone is a well-lit area of a lake or pond while the benthic zone represents an area around the bottom of any water body - marine or freshwater.
Light is an important factor for plants because the light is necessary for photosynthesis - a process through which plants get their foods. Hence, due to limited light in the benthic zone as opposed to the limnetic zone, plants would find it easier to survive in the latter compared to the former.

define thigmotropism, phototropism, and gravitropism and give an example of each
Answers
Answer:
a) Thigmotropism
b) Phototropism
c) Gravitropism
Explanation:
A) the turning or bending of a plant or other organism in response to a touch stimulus. example: the folding movement of the Mimosa pudica leaflets, can be considered as an example of thigmonastism.
B) the orientation of a plant or other organism in response to light, either towards the source of light ( positive phototropism ) or away from it ( negative phototropism ).example: Sunflower is a highly phototropic plant. They grow towards the sun and are also seen tracking the movement of the sun throughout the day. That is, the flower keeps changing its direction with the movement of the sun. Sunflower requires more light for its growth and survival.
C) The gravity-directed growth process, called gravitropism, dictates upward shoot growth to ensure a proper positioning of the leaves for efficient photosynthesis and gas exchange. example: tree has fallen over and due to gravitropism exhibits this arched growth.

In fission, how does the DNA of the daughter cells compare to the DNA of the parent cells?
It is exactly the same
It is different due to meiosis
It it mostly the same with slight changes
It is better than the parent DNA
Answers
Answer: It is exactly the same!
In fission, the DNA of the daughter cells compared to the DNA of the parent cells will be exactly the same. The correct option is A.
What do you mean by a parent cell and a daughter cell?The cell that divides to produce two daughter cells is known as the mother or parent cell in the process of cell division. Mitosis produces two offspring cells that are genetically identical to the mother cell. We are all alive now due to a process known as mitosis.
Mitosis is the process through which a single cell divides into two new, identical cells. The initial cell is known as the parent cell, while the newly created cells are known as the daughter cells.
The daughter cell is exactly identical to the mother cell, that's why the DNA will also be the same in both cells.
Therefore, the correct option is A. It is exactly the same.

Facial dimples and free earlobes are both considered dominant human traits. What are the expected phenotypes of the offspring of a female with dimples and free earlobes (DDFf) and a male with no dimples and attached earlobes (ddff)? Group of answer choices
Answers
Answer: 50% with dimples and free earlobes and 50% with dimples and attached earlobes
Explanation:
Since both the facial dimples and free earlobes are considered to be dominant human traits, this implies that the expected phenotypes of the offspring with regards to the scenario given in the question would be 50% with dimples and free earlobes and also there will be 50% with dimples and a attached earlobes.
50% with dimples and free earlobes and 50% with dimples and attached earlobes.
Dominant and recessive traits exist when a trait has two different forms at the gene level. The trait that first appears or is visibly expressed in the organism is called the dominant trait. The trait that is present at the gene level but is masked and does not show itself in the organism is called the recessive trait.Since both the facial dimples and free earlobes are considered to be dominant human traits, this implies that the expected phenotypes of the offspring with regards to the scenario given in the question would be 50% with dimples and free earlobes and also there will be 50% with dimples and an attached earlobes.
