Answer:
C. Three
Explanation:
Which molecule would most likely require a transport protein to cross the plasma membrane of a red blood cell?.
Glucose (C₆H₁₂O₆) is a large molecule which cannot cross the plasma membrane on its own therefore, it requires transport proteins (GLUT channels) through which they diffuse through membrane. Thus, the correct option is A.
How does materials transport through membrane?Materials transport through the plasma membrane through different ways which include active transport and passive transport. Active transport requires energy (ATP) for the transport of materials against the concentration gradient.
In passive transport, energy is not required as material moves in the direction of concentration gradient. The molecules can diffuse on their own through the plasma membrane and require transport proteins if the molecules are large in size or polar in nature. Facilitated diffusion has channel proteins and carrier proteins which helps in the transport of molecules across the membrane.
GLUT is a channel protein specific for the transport of glucose across the plasma membrane. Glucose is a large molecule hence requires a transport protein for diffusion across membrane.
Therefore, the correct option is A.

Answer:
The solubility of gases such as oxygen and nitrogen depends upon the ocean water's temperature and salinity. As the temperature of the ocean water increases, the solubility of these gases decreases. The solubility of carbon dioxide is greater than the other gases because of its ability to react with ocean water.

If trypsin were to be placed in an acidic environment, how would it function? How do you know?
Answer:
If trypsin is in an acidic environment, it will decrease its function, since its optimum pH is 8.
Explanation:
Trypsin is an enzyme responsible for break peptide bonds, thus hydrolyzing proteins into peptides and amino acids. This enzyme is secreted by the pancreas and poured into the duodenum —an alkaline environment— where it acts.
Since the optimal pH for trypsin to fulfill its function is 8, if the enzyme were placed in an acidic environment it would decrease its function. This is because enzymes work under specific pH and temperature conditions, and changes in these conditions affect enzymatic activity.

Diploid plants have two sets of chromosomes. Polyploid plants have more than two sets of chromosomes, are often targer, and have more desirable characteristics. To create polyploid plants, plant breeders can
treat diploid plants with a chemical that prevents the separation of sister chromatids during mitosis. Resulting cells that have any partial chromosome sets, even if in addition to one or more complete chromosome
sets typically do not survive this process
It a diploid plant ce treated with such a chemical goes through a single round of mitosis, what is the MOST LIKELY genetic composition of the resulting cells that survive?
А
These cells will be haploid, each having one complete set of chromosomes.
B
These cells will be triploid, each having three complete sets of chromosomes.
С
These cells will be tetraploid, each having four complete sets of chromosomes
These cells will be octaploid, each having eight complete sets of chromosomes.
To produce a tetraploid plant, the alkaloid colchicine is applied to the terminal bud of a branch. All the cells in the developing branch will be tetraploid (4n) with four sets of chromosomes. This includes cells of the stem, leaves, flowers and fruit. Gametes (egg and sperm) produced by a flower on this tetraploid branch will be diploid (2n) with two sets of chromosomes. A flower on the normal diploid (2n) branch will produce haploid (n) gametes containing one set of chromosomes.
Stages of mitosis in the formation of tetraploid cells. The original mother cell is diploid (2n). During anaphase the chromatids separate and move to opposite ends of the cell. Colchicine causes the dissolution (depolymerization) of protein microtubules which make up the mitotic spindle in dividing cells. This leaves the cell with twice as many single chromosomes (four sets rather than two). When this cell divides, each of the two daughter cells will have fours sets of chromosomes, a total of eight chomosomes per cell. [Note: Spindle poisons such as colchicine are used to prevent tumor cells from dividing in certain chemotherapy treatments.]
The botanical term parthenocarpy refers to the development of the ovary of a flower into a fruit without fertilization. [The biological term parthenogenesis refers to the development of an egg without fertilization.] Fruits that develop parthenocarpically are typically seedless. Some seedless fruits come from sterile triploid plants, with three sets of chromosomes rather than two. The triploid seeds are obtained by crossing a fertile tetraploid (4n) plant with a diploid (2n) plant. When you buy seedless watermelon seeds, you get two kinds of seeds, one for the fertile diploid plant and one for the sterile triploid. The triploid seeds are larger, and both types of seeds are planted in the same vicinity. Male flowers of the diploid plant provide the pollen which pollinates (but does not fertilize) the sterile triploid plant. The act of pollination induces fruit development without fertilization, thus the triploid watermelon fruits develop parthenocarpically and are seedless. Most bananas purchased at your local supermarket came from sterile triploid hybrids. The fruits developed parthenocarpically and are seedless.
