What are three things a scientist may see in a plant cell that would not be in an animal cell?​

If the substances can move across the cell membrane without the cell expending energy, the movement of molecules is called passive transport.

A type of cellular transport known as passive transport involves the movement of molecules and ions along concentration gradients. It indicates that a drug has a propensity to migrate from a region of higher concentration to a region of lower concentration.

Unlike to active transport, another type of cellular transport, which fundamentally requires ATP to move substances against their concentration gradient, the process does not require metabolic energy (e.g. ATP) because the chemicals are moved downhill or along their concentration gradient.

The four main methods of passive transport are osmosis, filtration, simple diffusion, and assisted diffusion.

Therefore, If the substances can move across the cell membrane without the cell expending energy, the movement of molecules is called passive transport.

Answer:

Receptor on the outer cell surface.

Explanation:

Hydrophilic signal molecules are the water soluble molecules, they are polar polar and therefore cannot pass through the non-polar center of the plasma membrane without any mediator. Water-soluble ligands bind to the extracellular domain of cell surface receptors. Signal molecules cannot enter the cell and thus plasma membrane receptor is required. Plasma membrane receptor form an important class of integral membrane proteins that transmit signals from the extracellular space into the cytoplasm. This group of signal molecules is quite diverse and most are based on amino acids. In some cases the unmodified amino acid is the signal molecule, in others the amino acid is modified into a derivative and in still others amino acids are combined into peptides and proteins.

Answer:

During interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.

The pair of ligaments covered by laryngeal epithelium that function in sound production are the vocal cords or vocal folds.

The vocal cords, also known as vocal folds, are a pair of ligaments covered by laryngeal that are located within the larynx, or voice box. They play a critical role in sound production by vibrating when air is passed over them, producing sound waves that can be modified by the muscles of the larynx, mouth, and throat to produce speech and other vocalizations. The vocal cords are composed of layers of muscle, connective tissue, and mucous membrane. They are controlled by several muscles, including the thyroarytenoid muscle, which is responsible for adjusting the tension on the vocal cords to produce different pitches and tones.

The oxidation of 1 molecule of NADH by nitrate (NO3-) would yield approximately 4.3 ATP molecules per NADH molecule due to its reduction potential at 0.54 V.

The standard reduction potential of elemental sulfur (S) is at 0.04 V and therefore in the oxidation of 1 NADH molecule, it would synthesize around 1.2 ATP molecules per NADH molecule. The oxidation of NADH by ½ O2 molecule yields approximately 2.5 ATP molecules per NADH molecule due to the reduction potential of oxygen at 0.82 V.

The amount of ATP molecules generated from each of the terminal electron acceptors in NADH oxidation show the significant influence that the reduction potentials of the different terminal electron acceptors have on the amount of ATP the bacteria can synthesize.

The spreading out of molecules in the air from a center of concentration is caused by diffusion. Diffusion is the movement of molecules from a region of high concentration to a region of low concentration.

This process occurs due to the random motion of particles, and it is driven by the natural tendency of particles to move from an area of high concentration to an area of low concentration.

Diffusion plays a vital role in many natural processes, including gas exchange in the lungs, transport of nutrients and waste products across cell membranes, and the release of odor molecules into the air.

In each of these processes, the molecules move from a region of high concentration to a region of low concentration due to the natural tendency of particles to spread out and become evenly distributed over time.

The rate of diffusion is influenced by several factors, including the concentration gradient, the temperature of the environment, and the size and shape of the molecules involved.

Diffusion can be a slow process, particularly over long distances or in areas where the concentration gradient is small, but it is a fundamental mechanism that underlies many of the processes that allow living organisms to function and survive.

Overall, the spreading out of molecules in the air from a center of concentration is an essential process that is driven by the natural tendency of particles to diffuse and become evenly distributed over time.

Answer:

When a genetic disorder is diagnosed in a family, family members often want to know the likelihood that they or their children will develop the condition. This can be difficult to predict in some cases because many factors influence a person's chances of developing a genetic condition. One important factor is how the condition is inherited. For example:

Autosomal dominant inheritance: A person affected by an autosomal dominant disorder has a 50 percent chance of passing the mutated gene to each child. The chance that a child will not inherit the mutated gene is also 50 percent. However, in some cases an autosomal dominant disorder results from a new (de novo) mutation that occurs during the formation of egg or sperm cells or early in embryonic development. In these cases, the child's parents are unaffected, but the child may pass on the condition to his or her own children.

The correct explanation is: In an experiment such as this, you are only assessing one part (your sample) of a much larger population.

Therefore, a larger sample size helps to increase the chance that results obtained are reflective of the population as a whole because you are gathering data from a larger percentage of the population. By increasing the sample size to at least 100 participants, the student can obtain a more representative sample of the population and reduce the potential for sampling bias. This increases the generalizability of the findings and allows for more accurate conclusions about the relationship between movie genre and popcorn consumption.

\(BrainiacUser1357\)

The model that shows the positions of the Sun, Moon, and Earth that have the greatest effect on ocean tides is the spring tide model.

During spring tides, the Sun, Moon, and Earth are in alignment, which causes the gravitational pull of the Sun and Moon to reinforce each other, leading to higher high tides and lower low tides.

Spring tides occur twice a month, during the new moon phase and the full moon phase.

In contrast, neap tides occur when the Sun, Moon, and Earth form a right angle, which causes the gravitational pull of the Sun and Moon to counteract each other.

This leads to lower high tides and higher low tides. Neap tides also occur twice a month, during the first and third quarter moon phases.

It's important to note that the positions of the Sun, Moon, and Earth aren't the only factors that affect ocean tides. Other factors, such as the shape of the coastline and the depth of the ocean floor, can also influence the height and timing of tides in a particular area.

RNA polymerases are the enzymes involved in transcription. RRNA makes up the majority of a RNA in cells; mRNA makes up about 3-5% of a cell's total RNA.

To create a fresh, complementary RNA molecule, RNA polymerase employs a single Stranded dna (the template to make) as a template. Termination is the procedure that puts a stop to transcribing. The RNA sequences that indicate that the translation is finished rely on termination. Where does the transcription of a gene to mRNA by RNA polymerase start? It begins following a certain nucleotide pattern known as a promoter. What role does RNA polymerase play? The expanding strand of RNA receives nucleotides as the double helix is unwound. RRNA genes are transcribed by RNA polymerase I, mRNA, miRNA, snRNA, or snoRNA genes are transcribed by RNA polymerase II, while tRNA & 5S rRNA genes are transcribed by RNA polymerase III.
