Answer:
•The dodder plant is parasitic.
•The dodder plant stays alive because of the potato plant.
Explanation:
A parasite cannot survive or reproduce without its host because it depends on it. The dodder plant is parasitic to the potato plant because it derives its nutrition from the potato plant which is the host. The potato plant is denied its nutrient and therefore grows weakly below its maximum potential. The dodder plant gains while the potato plant is negatively affected- that’s parasitism relationship.
Answer: Chloroplast
Explanation: Pigments give the chloroplast and the plant its color.
The liver receives the oxygen and nutrients it needs in blood that comes from two large blood vessels:
Portal vein.
Hepatic artery.
The liver is connected to two large blood vessels, the hepatic artery and the portal vein. The hepatic artery carries blood from the aorta to the liver, whereas the portal vein carries blood containing the digested nutrients from the entire gastrointestinal tract, and also from the spleen and pancreas to the liver.
Answer:
The correct order is F, E, C, G, H, A, D, and B (look at the image in the attached files)
Explanation:
- <u>Interphase</u><u>:</u> Stages G1, S, and G2. At this point probably, the chromatin duplication has already occurred, but it is still lax or dispersed. It has not condensed yet. Two pairs of centrioles are outside the nucleus (FIGURE F)
- <u>Prophase</u>: Centrioles move forward to the opposite poles of the cell. Chromatin is condensed and individual chromosomes are now visible. The nuclear membrane breaks into many pieces. Spindle apparatus -microtubules- forms. (FIGURE E)
- <u>Metaphase:</u> The polar and the kinetochore fibers drive each individual chromosome to the equatorial plane. This stage ends when all the chromosomes are completely arranged in the medial area. (FIGURE C)
- <u>Anaphase</u>: Sister chromatids separate and move to the opposite poles of the cells, driven by the microtubules. In each pole, there are a pair of centrioles (FIGURE G and H).
- <u>Telophase</u>: The nuclear membrane rearranges. Each sister chromatid becomes now a new chromosome. There is a pair of centrioles outside each of the nuclei. (FIGURE A)
- Cytokinesis occurs at the end of the cell division. The rest of the cell is divided into two new daughter cells. Each daughter cell is an identical copy of the other cell, with the exact same genetic material (FIGURE D).
- Decondensation of the genetic material of each new cell (FIGURE B).

Solution:
The function of a protein is determined by its shape.
The shape of a protein is determined by its primary structure (sequence of amino acids).
The sequence of amino acids in a protein is determined by the sequence of nucleotides in the gene (DNA) encoding it.
