Small nonpolar molecules, consisting of O2 and CO2, are soluble in the lipid bilayer and consequently can effectively cross cell membranes. Small uncharged polar molecules, which include H2O, can also diffuse thru membranes, however large uncharged polar molecules, inclusive of glucose, cannot.

Explanation: Molecules pass throughout the plasma/mobile membrane through diffusion. If they're not small sufficient, they need to break down by means of other substances, which include enzymes, which can be biological catalysts. If they are small enough, usually, the easiest way for them to move is through diffusion.

According to the given information, a farmer grows red, white, and pink carnations for a local flower shop. He can obtain the standard Mendelian ratio of 1:2:1 of white: pink: red flowers by letting the flowers self-cross.

The flower color phenotype exhibits incomplete dominance, and all heterozygous flowers are pink. Homozygous flowers are either red or white. The farmer wants the plants to produce enough of each color flower to meet customer demand, which is conveniently the standard Mendelian ratio of 1:2:1 of white: pink: red flowers.

He hypothesizes that this ratio can be obtained by letting the flowers self-cross. He plants 1000 total seed of 250 white flowers, 250 red flowers, and 500 pink flowers and lets the plants self-fertilize and perpetuate over three growing seasons.

He predicts the ratio will remain the same each generation.Analysis of collected data: The farmer predicts that by letting the flowers self-cross, the ratio will remain the same in each generation. The ratio of white: pink: red flowers in the first generation is 1:2:1, which is exactly what the farmer wanted. If the same ratio is maintained, then the second and third generations should also have the same ratio of white: pink: red flowers. Conclusion:The farmer's results confirm that his hypothesis was correct.

The results of his self-crossing experiment showed that the ratio of white: pink: red flowers remained the same in each generation, exactly what he had predicted. Thus, he can obtain the standard Mendelian ratio of 1:2:1 of white: pink: red flowers by letting the flowers self-cross.

The main barrier that limits the diffusion of polar molecules across a plasma membrane is the hydrophobic core of the membrane of the membrane.

Polar molecules can't diffuse via the bilayer. Polar molecules want polar protein channels to diffuse via the membrane. This is "facilitated diffusion". Small nonpolar molecules can effortlessly diffuse throughout the mobileular membrane. However, because of the hydrophobic nature of the lipids that make up mobileular membranes, polar molecules (consisting of water) and ions can't do so. Instead, they diffuse throughout the membrane via delivery proteins. Polar molecules are much less loose to diffuse throughout membranes. In order for a polar molecule to move a membrane, it need to ruin its interactions with water because it enters the hydrophobic indoors of the bilayer.

Because one of the roses is purebred dominant, all recessive genes will be overshadowed.

One evolutionary advantage of sexual reproduction is that it creates more genetic variation in a population than asexual reproduction. This increased genetic variation is an advantage because it enables populations to better adapt to changing environments.

In sexual reproduction, offspring inherit a combination of genes from both parents, resulting in unique genetic combinations that increase the population's diversity. This diversity helps to ensure that some individuals will possess traits that improve their chances of survival and reproduction in various environmental conditions.

As a result, a population with greater genetic variation is more likely to withstand selective pressures, such as diseases or predators, and thrive over time.

Overall, the genetic variation provided by sexual reproduction contributes to a population's adaptability and long-term survival.

Answer:  The arrangement of these nitrogen bases contains the code for

genetic traits. These bases are arranged in a particular

sequence, such as TGCATTCA. The sequences of DNA can vary

from several hundred bases to a million or more bases.

Explanation: put this and my teacher said amazing  

The complementary side’s bases if one side of a DNA molecule has the following sequence of nitrogen bases GGTACTTACGCA are: CCTGAAATGCGT.

Thus, the complementary nitrogen base sequence of GGTACTTACGCA is CCTGAAATGCGT. It is because the complementary nitrogen bases pair up: A always pairs with T, and C always pairs with G.

The sequence codes for 4 amino acids. Every three nitrogen bases code for one amino acid. So, since there are 12 nitrogen bases, the sequence codes for 12/3 = 4 amino acids.

To determine the number of amino acids coded by this sequence, first note that a codon consists of three nucleotide bases, and each codon corresponds to one amino acid. The sequence has 12 bases, so there are 4 codons: GGT, ACT, TAC, and GCA. Since each codon codes for one amino acid, this sequence would code for 4 amino acids.

The system that rids the body of nitrogen-containing wastes is the excretory system. This system plays a crucial role in maintaining homeostasis by eliminating harmful substances, such as nitrogen-containing wastes, from the body. The primary organs involved in this process are the kidneys, which filter the blood and produce urine, containing the nitrogenous waste products. Urine is then transported through the ureters, stored in the urinary bladder, and eventually expelled from the body through the urethra.

The renal system, specifically the kidneys, are responsible for ridding the body of nitrogen-containing wastes. This process occurs through the formation of urine, which is made up of excess water, salts, and nitrogenous wastes such as urea and creatinine. The kidneys filter the blood and remove these waste products, which are then excreted through the urinary tract. The body produces nitrogen-containing wastes as a result of protein metabolism, and it is essential to eliminate them from the body to prevent the buildup of toxic substances. Therefore, the renal system plays a vital role in maintaining the body's balance of nitrogen-containing wastes within the bloodstream. In summary, the excretory system efficiently removes nitrogen-containing wastes, ensuring overall health and proper bodily functions.

The properties of the plasma membrane that contribute to its selective permeability are the Phospholipid bilayer, Membrane proteins, and Cholesterol.

The plasma membrane is selectively permeable, which means it allows some substances to pass through while preventing others from entering or leaving the cell. The following properties of the plasma membrane contribute to its selective permeability:

(1) Phospholipid bilayer: The plasma membrane is composed of a double layer of phospholipids, with hydrophilic (water-loving) heads facing outward and hydrophobic (water-fearing) tails facing inward. This structure creates a barrier that prevents the movement of hydrophilic molecules, such as ions and polar molecules, through the membrane.

(2) Membrane proteins: The plasma membrane contains a variety of proteins that are embedded within the phospholipid bilayer. These proteins have different functions, including the transport of specific molecules, enzymatic activity, signal transduction, and cell-cell recognition. The presence of specific transport proteins, such as channels and carriers, allows the membrane to regulate the movement of certain molecules in and out of the cell.

(3) Cholesterol: Cholesterol molecules are interspersed within the phospholipid bilayer, which helps to maintain membrane fluidity and stability. This property allows the plasma membrane to selectively adjust its permeability depending on the needs of the cell.

Together, these properties allow the plasma membrane to selectively permit the passage of certain molecules while blocking others. This process helps to maintain the internal environment of the cell and to regulate the movement of substances in and out of the cell.
