Explanation:
As illustrated in this question, Gregor Mendel used the color trait of pea plant to discover his law of dominance.
The results Mendel obtained during his experiments. It showed that if you cross two plants that were true breeding for different colors (purple and white), the offspring or first generation (F1) would be HETEROZYGOUS (Pp) instead of true-breeds, and all were PURPLE in color.
Interestingly, when he crossed two of these F1 plants (Pp × Pp), their offspring did not all come out PURPLE, instead he obtain a ratio of 3 purple-flowered plant for every 1 white-flowered plant. He concluded that the “heritable factor” for the RECESSIVE trait (white flowers) was not destroyed in the F1 generation. Instead it had been MASKED by the “heritable factor” of the DOMINANT trait (purple flowers).
Answer:
C, E, B, D, A
Explanation:
Mitosis is the process by which a cell divides to form two cells. This involves the duplication of the genetic material. Therefore, mitosis begins with one diploid cell (diploid = 2 copies of the genome), and ends with two diploid cells (C).
Mitosis is a widespread process, occurring in all eukaryotic cells. This includes humans, animals, and single cell species (E)
Mitosis generates new daughter cells with the same genetic information as the parent cells, therefore it results in cellular reproduction, and regeneration of the individual organism through faithfully copying the genetic material (B)
Mitosis is a type of cell division. In mammals, a specialized type of cell division called meiosis is the process that is important for sexual reproduction. In some single celled organisms, mitosis can lead to a process of asexual reproduction in which the cell divides in two, producing a replica with an equal number of chromosomes (D)
Mitosis involves the passing on the genetic information, and increasing the number of cells (proliferation). Therefore, it is involved in development and growth of an organism, replacing old cells, and in asexual reproduction (some organisms can perform "budding" to reproduce using mitosis) (A)
Answer:
Plankton and Algae
Explanation:
Adult zebra mussels feed by filtering large amounts of plankton and detritus from the water. Each mussel can filter one liter of water per day! Zebra mussels thrive in nutrient-rich water which supports healthy populations of plankton.
Answer:
The answer is option C.
Explanation:
The question is not complete, here is the complete question:
A person picks up a heavy suitcase in order to estimate its weight and reflexively drops it. Which of the following receptors has initiated this reflex?
A) Free Nerve Ending
B) Lamellae Corpuscle
C) Tendon Organ
D) Bulbous Corpuscle
The answer is option C, the tendon organ. Tendon organ, located in the skeletal muscles, takes on the role of sensing the tension in the muscle so that it can be adjusted appropriately. In this case, the weight of the suitcase was not estimated correctly so the tension of the skeletal muscle was not enough to hold the suitcase.
I hope this answer helps.
